Full description

Background of the invention

Embodiments of the present invention relate generally to a wireless mobile communication system, and more specifically to a method for performing a Hybrid Automatic Repeat reQuest (HARQ) process in a mobile wireless communication system.

Wireless mobile communication systems have been developed to provide a variety of services including broadcasting service, multimedia video service, multimedia messages service, etc. In particular, the future generation of wireless mobile communications systems being developed aims to provide data service at 100 Mbps or more to fast moving users and at 1 Gbps or more to slow moving users. In a wireless mobile communication system, it requires a low control cost and a short latency period for high-speed reliable transmission and reception of data between a Base Station (BS) and a Mobile Station (MS). To reduce the control cost and a short latency period, a technology is used. Hybrid Automatic Repeat reQuest (HARQ).

When a sender sends a signal carrying data to a receiver, the receiver responds with an ACKknowledgment (ACK) signal indicating that the signal was received successfully or a negative ack (NACK) signal indicating that the signal was not received The sender in a wireless mobile communication system performs a repeated request Hybrid Automatic Repeat reQuest (HARQ). After receiving an ACKnowledgment (ACK) or negative ack (NACK) signal, the sender first sends new data or sends sent data to the receiver according to the Hybrid Automatic Repeat reQuest (HARQ) scheme. There are two major halogenated redundancy schemes: Chase Combining (CC) and Incremental Redundancy (IR).

Transmission and reception are performed on a frame basis during a hybrid automatic redundant dialing process, which does not reduce the latency period. Accordingly, a new frame structure that shortens the latency of signal transmission and reception, and a timing structure for the hybrid automatic redundant request process are needed to implement the new frame structure.

Accordingly, it should be apparent to those skilled in the art that the following description of representative examples of the present invention is provided for illustrative purposes only and not for the purpose of limiting the invention as defined by the following claims and their equivalents.

The singular form "a", "an" and "the" are understood to refer to the plural unless the context clearly states otherwise. Thus, for example, when a reference is made to a “component surface,” the reference includes one or more of those surfaces.

Representative embodiments of the present invention relate to a method for performing a Hybrid Automatic Repeat reQuest (HARQ) operation using a specified Hybrid Automatic Repeat reQuest (HARQ) retransmission latency in a wireless mobile communication system operating in Frequency Division Duplex (FDD), Time Division Duplex, Half Duplex-FDD (H-FDD) or both frame frequency division duplex and time division duplex. In time division duplex or half duplex, a frame can be formed at different DownLink (DL) to UpLink (UL) ratios. Thus, the duration of the downlink and the duration of the uplink may be the same or asymmetric in a frame.

Below, the transmission and reception of a signal between a Base Station (BS) and a Mobile Station (MS) will be described based on a hyperframe structure according to the Hybrid Automatic Repeat reQuest (HARQ) scheme. Each superframe has one or more frames, and each frame has one or more subframes. The term "subframe" can be used interchangeably with "time gap." Each time slot or subframe includes one or more Orthogonal Frequency Division Multiple Access (OFDMA) codes.

In an embodiment, the Base Station (BS) and Mobile Station (MS) may each include a control unit to generate and analyze data batch allocation information to determine the transmission time of a Hybrid Automatic Repeat reQuest (HARQ) according to a described frame structure. Subsequently and timing of the hybrid automated recurring request process, at least one hybrid automated recurring request processor for generating and analyzing a data batch, a data batch, and a hybrid automated recurring request response at specified times under the control of the controller and a transceiver for sending and receiving data batch allocation information, and a batch Data,hybrid automated recursive request. For example, the data burst assignment information can be communicated as an Information Element (IE) and an Advanced MAP (A-MAP) specifying the source assignment, and the transmission of the data burst can be sent as a subpacket generated by a hybrid automated recurring request. According to a hybrid automated recurring request process.

Figure (1) shows a Frequency Division Duplex (FDD) superframe structure according to a representative embodiment of the present invention.

Referring to Figure (1), the superframe (100) includes four frames (110), each of which has eight subframes. In a Frequency Division Duplex (FDD) frame, the DownLink (DL) subframes (120) going from the Base Station (BS) to the Mobile Station (MS) and the Uplink subframes (120) going from the MS are occupied Portable to base station different frequency bands.

Figure (2) shows the structure of a Time Division Duplex superframe according to a representative embodiment of the present invention.

Referring to Figure (2), the superframe (200) includes four frames (210), each of which has eight subframes (220). In a Time Division Duplex frame, a specified number of subframes out of the total subframes are used as Downlink (DL) subframes and the remaining subframes are used as Uplink subframes in each frame. In the case shown in Figure (2), the ratio of downlink to uplink is set as 5:3, which includes five downlink subframes being defined during its time period and three uplink subframes being defined during the uplink time period, and is interpolated. Receive/transmit Transition Gap (RTG) gap (240) between an uplink subframe and the next downlink subframe.

While in Figures (1, 2) each superframe has four frames each with eight subframes, F may vary depending on the bandwidth and subcarrier separation of the wireless mobile communications system in vertical frequency division duplex/ Multiplexing/Orthogonal Frequency Division Multiple access for a wireless mobile communication system having channel bandwidths of 5, 10, and 20 MHz, with each frame having eight subframes, where The number of subframes per frame is 7 in a VFD multiple access mobile/wireless communications system and has a channel bandwidth of 8.75 MHz. In addition, a 7 MHz VFD multiple access wireless mobile communication system can have six subframes per frame. Additionally, for a given bandwidth, the number of subframes per frame may vary depending on the specified Cyclic Prefix (CP) length.

In a Hybrid Automatic Repeat reQuest (HARQ), the timing of an initial transmission and the timing of a retransmission can be placed in a particular transition relationship. This transition relationship is referred to as the timing structure of a hybrid or interlocking automated repetitive request process. The timing structure of a hybrid automated redundant request or interleaving process refers to the relationship between a subframe carrying a MAP message containing source assignment information (i.e., control information) and a subframe carrying a signal associated with a subframe carrying the MAP message, and the relationship between a subframe carrying the signal and a subframe The response to the signal carries, and the relationship between a reply subframe and a subframe carrying first transmission data or retransmission data depending on the response. Below is a more detailed description of the timing structure of the Hybrid Automatic Repeat reQuest (HARQ) process.

Information Element (IE) Data batch assignment: between a downlink data batch or an uplink data batch in a downlink subframe.

Data Batch: A sender sends a data batch in custom sources using the Information Element (IE) Customize Data Batch.

Hybrid Automatic Repeat reQuest (HARQ) to a received data batch: A receiver that sends an ACKknowledgment (ACK) signal or negative ack (NACK) signal according to an error in the received data batch.

Initial transmission of the data burst according to Hybrid Automatic Repeat reQuest (HARQ): The sender sends the data burst after receiving a negative ack (NACK) signal. The sender can also provide source allocation information for retransmission. On the other hand, after receiving the ACKnowledgment (ACK) signal, the sender can first send a new data burst.

Hybrid Automatic Repeat reQuest (HARQ) schemes can be classified into asynchronous HARQ and synchronous HARQ. The timing structure of the hybrid automated recurring request process defined in (1), (2), and (3) needs to be defined as an asynchronous hybrid automated recurring request process, while the timing structure of the hybrid automated recurring request process defined in (1-4) needs to be defined As a hybrid synchronous automated recurring request process. To define these hybrid auto redundant timing structures, at least one DownLink (DL) subframe in a downlink period must be in a specified transition relationship with at least one uplink subframe in an uplink period.

Hybrid automatic redundant operation timings for Frequency Division Duplex (FDD) and Time Division Duplex (FDD) modes will now be described.

Figure (3) is a diagram showing the timing structure of a hybrid automatic repeat dialing process for sending a downlink data batch) in a Frequency Division Duplex (FDD) frame according to a representative embodiment of the present invention. As shown in Figure (3), the timing structure of the hybrid automatic repeat dialing process is designed to send the downlink data batch in frequency division duplex, based on the structure of the frequency division duplex frame shown in Figure (1). It is assumed that the number of frames per superframe, N = 4, that the number of subframes per frame F = 8, that the Transmission/Reception (Tx/Rx) processing time of a data batch is three subframes and that the skew of an automatic redundant request reply The downlink hybrid is labeled z = zero and the automatic redundant transmission deviation of the downlink hybrid is labeled u = zero. The processing time for Transmission/Reception (Tx/Rx) is defined as the time required to send the following data after receiving a hybrid automatic redundant request response from the sender, and the processing time for Transmission/Reception (Tx/Rx) is defined as the time required to send a redundant request response Hybrid automatic after receiving data at the receiver.

Referring to Figure (3), the sender sends data batch assignment information and a DownLink (DL) data batch in downlink subframe 1 (i.e., downlink subframe No. l 300 of frame i in the downlink frequency band). The receiver then sends Hybrid Automatic Repeat reQuest (HARQ) response to a downlink data burst in an uplink subframe 5 310 of frame i in an uplink frequency band. The sender transmits the data burst in the downlink subframe 1 320 of frame (1+i) in the downlink frequency band next if the HARQ is a negative ack (NACK) signal. For the transmitted data batch, the receiver sends a Hybrid Automatic Repeat reQuest (HARQ) in uplink subframe 5 330 of frame (i+1) in the uplink frequency band.

To describe the previous Hybrid Automated Recurring Request process with reference to Table 1 below, the index of a subframe carrying the HARQ is n=5 and is determined by calculating {ceil(1+4) mod 8}, The coefficient of the frame carrying a Hybrid Automated Recurring Request (HARQ) j = i is determined by calculating {i+floor(ceil(1+4)/8)+0}, and the coefficient of the frame carrying a HARQ data batch ( HARQ), i+1=K is determined by the calculation {j+floor((5+4)/8)+0}. "ceil" is a function that rounds the variable down to the nearest integer, and "floor" is a function that rounds the variable down to the nearest integer.

Table 1 contains the timing structure of a Hybrid Automatic Repeat reQuest (HARQ) downlink-frequency division duplex process according to a representative embodiment of the present invention. Table 1 may be used to determine the transmission time for at least one advanced information element assignment using data batch assignment information, an ACK subpacket carrying the data batch, an ACKnowledgment (ACK), or a negative ack signal. (NACK) signal), and a subpacket response to retransmit the HARD. However, it is understood that Table 1 should not be considered a limitation of the present invention.

In Table 1, N denotes the number of frames per superframe. If each superframe has four subframes, then N = 4. F stands for the number of subframes per physical frame. For example, N = 4 and F = 8 for bandwidths of 5, 10, and 20 MHz. i, j, and k stand for DownLink (DL) frame indexes or uplink frame indexes. l stands for the index of a subframe of a downlink carrying the data batch assignment information, m stands for the index of a subframe of a downlink carrying an initial transmission data batch, and n stands for the index of a subframe for the uplink Holder for a Hybrid Automatic Repeat reQuest (HARQ) response to a received data batch.

In addition, z denotes the deviation of the downlink hybrid automatic repeating request response. We symbolize the downlink deviation of the downlink hybrid automatic repeating request with time processing.

Both z and as a number of frames are represented. Thus,,,,,,.

NA-MAP is the transmission period of data batch allocation information expressed as the number of subframes. Data batch allocation information is communicated in a typical MAP or Advanced Information Object message. If data batch assignment information is sent in every other Downlink (DL) subframe then NA-MAP = 1. If data batch assignment information is sent in every other Downlink subframe then NA-MAP = 2. in this case.

For transmitting and receiving a hybrid automatic downlink repeat request with frequency division duplex shown in Figure (34), F = 8, N = 4, z = zero, and u = zero. The downlink data burst assignment information sent in the first downlink subframe 300 of frame i indicates that the subframe is downlink number m of frame i. When the transmitted data burst assignment information is transmitted in each downlink subframe (i.e. NA-MHP = 1), the data burst assignment information shows that the transmission of the data burst started in the downlink subframe, that is, m = 1 On the other hand, when data burst assignment information is sent in every other downlink subframe, this indicates that the transmission of the data burst begins in DownLink (DL) subframe number l or (1+ l), That is, m = l or (1 + l). Pertinent information indicating l or (1+ l) is included in the data batch assignment information.

The data batch indicated by the data batch assignment information may occupy one or more downlink subframes. The Transmission Time Interval (TTI) of a data burst starting in downlink subframe number m is denoted by NTT1. That is, NTT1 is the number of subframes over which a data burst extends. For example, NTT1 can be pre-determined or signaled by data batch allocation information.

If the data burst spans one subframe then NTT1 = 1, and if the data burst spans four subframes then NTT1 = 4.

A Hybrid Automatic Repeat reQuest (HARQ) is sent to a data batch initiated in DownLink (DL) subframe m of frame i in Uplink subframe n of frame j. According to the index of a subframe carrying the data batch, m and n are given as follows:

n = ceil(m+F/2) mod F. . . . . (1)

For the frame indexes of the uplink carrying a hybrid automatic redundant request, j is determined according to the index of a subframe m and the frame index i of the data batch. Frame drift is created by the time gap between the transmission of the data burst and the time a hybrid automated redundant request response is sent. The time gap, symbolized by Cap1, is calculated by:

. . . . . (2)

where NTT1 is a data burst interval transmission in a downlink hybrid automatic redundant process expressed as a number of subframes, and F denotes the number of subframes per frame.

Because the conduction periods are staggered in a Frequency Division Duplex (FDD) system, Gap1 is frame-selected, regardless of the subframe parameters.

In a downlink hybrid automatic repeat request, the deviation of the downlink hybrid automatic repeat request response is determined so that Gap1 mentioned in equation (2) is the processing time RX. For example, if Gap1 is the processing time RX, then z = zero, while if Gap1 is the processing time RX, then z = 1. The value of z is set so that a Hybrid Automatic Repeat reQuest (HARQ) response is sent in its subframe. The same factor as frame indexes is delayed. In fact, z is a deviation expressed as the number of frames, which does not mean that the index of a subframe carrying the HARQ has changed.

After determining z in this way, j is

. . . . . (3)

When a Downlink (DL) data batch is retransmitted in an asynchronous Hybrid Automatic Recurring Request (HARQ), the retransmission time of the downlink data batch is indicated by a retransmission indicator located in the data batch assignment information. At the same time, if a downlink data batch is retransmitted in a synchronous hybrid automatic repeat request, the retransmission occurs in subframe m of frame k. Referring to Table (1), the frame coefficient k is determined. Referring to Table (1), the frame factor k is determined based on the factor j of the frame carrying a hybrid automatic repeat request reply, and the index of a subframe carrying the retransmission data batch is the same as the index of a subframe of the previous transmission of the transmission data batch. Frame drift is generated by the time gap between the transmission time of a hybrid automatic redundant request and the transmission of the data burst. The data gap symbolized by Gap2 is given by:

. . . . . (4)

Where NCTRL, TT1 denotes a hybrid automated repeat request (HARQ) interval transition in a hybrid automated repeat request (HARQ) process, and F denotes the number of subframes per frame. Because the delivery periods are staggered in a Frequency Division Duplex (FDD) system, Gap2 is determined using the uplink transmission interval, and the number of subframes per frame, regardless of the subframe coefficients. A hybrid automated recursive request response usually crosses a single subframe.

In a downlink hybrid auto-repeater, the downlink hybrid auto-repeat deviation called u is determined so that the Gap2 mentioned in Equation (4) is the processing time TX. For example, if Gap2 is the processing time TX, then u = 0, while if Gap2 is the processing time Tx, then u = 1. The value of u is adjusted so that the next hybrid automated redundant request data is sent in a delayed frame. In fact, u is a deviation expressed as a number of frames, which does not mean that the index of a subframe carrying the Hybrid Automatic Repeat reQuest (HARQ) data has changed.

After u is defined in this way, k is

. . . . . (5)

As mentioned before, if the time required to process a transmission signal is not secured, the retransmission time (HARQ) can be delayed by one frame (i.e. u = 1). “Sufficient time” indicates that the time required to process the transmission of a signal (processing time Tx) and the time required to process the reception of a signal (processing time Rx) exceed a known reference value. The reference value is first set or broadcast by the system.

If the frame coefficients j and k are the number of frames per superframe, and N is the superframe coefficient, then s is increased by 1 and the frame coefficients j and k are the values obtained by calculating the equations inside the parentheses in equations (3) and ( 4). Referring to Figures (1, 2), it can be considered that N =4.

Referring to equations (2, 4), it is possible to determine the deviation of the response of a downlink hybrid automatic repeat request, called z, and the deviation of a downlink hybrid automatic repeat request with a time processing of a downlink, called u, using the Transmission Time Interval (TTI). reQuest (HARQ) (Transmission Time Interval (TTI) of a data batch or reply) and the signal processing capability of the system (sender and receiver) in a Frequency Division Duplex (FDD) frame. Information about the ability to process or broadcast the signal can be pre-determined by the system. It can also be projected as another representational model in which z and u are broadcast in system body information according to the system process diagram.

Figure (4) is a diagram showing the timing structure of a downlink hybrid automatic repeat dialing process for sending an uplink data batch in Frequency Division Duplex (FDD) according to a representative embodiment of the present invention. Assuming that the number of frames per superframe, N = 4, the number of subframes per frame F = 8, the processing time RX/RX = 3 subframes, the skew of the downlink hybrid automatic redundant request called w = zero and the uplink skew of the downlink request A hybrid iterative automata with a time processing labeled v = zero.

Referring to Figure (4), after receiving the data batch assignment information in a DownLink (DL) subframe 1 400 of frame i in the downlink frequency band, the sender sends an uplink data batch in an uplink subframe 5 410 of frame i in Uplink frequency range. The receiver sends a Hybrid Automatic Repeat reQuest (HARQ) in the 1 420 downlink subframe of the (1 + i) frame in the downlink frequency band, depending on whether the received data batch contains an error or not. If the hybrid auto redundant reply is a negative ack (Nack) signal, the sender retransmits the transmission of the data burst in the uplink subframe 5 430 of frame (1 + i) in the uplink frequency range. If the downlink subframe 420 carries data burst assignment information indicating an uplink burst retransmission, then an uplink data burst retransmission is performed in accordance with the data burst assignment information.

To describe the previous hybrid automatic redundant process with reference to Table 2 below, the parameter of the frame carrying an uplink data burst called j is i and is determined by calculating {i+floor(ceil(1+4)/8)+0} mod 4 The index of a subframe carrying an uplink data burst, m = 5, is determined by calculating {ceil(1+4) mod 8}, and the index of the frame carrying a hybrid automatic redundant request response, K, is i(j=1). )+1 and is determined by the calculation {j+floor((5+4)/8)+0} mod 4. The index of a subframe carrying the HARQ is 1. If the HARQ response is a NEGATIVE ACK (NACK) SIGNAL, the index of the frame carrying the retransmission of the HARQ data batch is +1. i is determined by the calculation ((k+floor(ceil(1+4)/8)+0) mod 4), and the subframe parameter carrying the retransmission of a Hybrid Automatic Repeat reQuest (HARQ) data batch, called m = 5.

Table 2 contains the timing structure of a hybrid frequency division duplex uplink automatic redundant process according to a representative embodiment of the present invention. Table 2 may be used to determine the transmission time of at least one A-MAR assignment using data batch assignment information, a subpacket (HARQ) carrying the data batch, a Hybrid Automatic Repeat reQuest (HARQ) for ACKnowledgment (ACK), or negative ack signal (NACK) signal), and a subpacket for retransmitting a hybrid automated repeat request. However, it is understood that Table 2 should not be considered a limitation of the present invention.

In Table 2, N refers to the number of frames per superframe. If each superframe contains four subframes, then N = 4. F denotes the number of subframes per frame, and i, j, k, and p denote the uplink frame indexes or DownLink (DL) frame indexes. l denotes the downlink subframe parameter of a data batch assignment information bearer, m denotes the uplink subframe parameter at which a data batch transmission begins, w denotes the downlink hybrid automatic redundant reply deviation, and v denotes the uplink deviation of a request Hybrid automated iterative with temporal processing. Both w and v are represented as a number of frames. Thus, , , , , , , and .

NA-MAP indicates the allocation information period of a data batch, expressed as a number of subframes. If data batch assignment information is sent in every other downlink subframe, then NA-MAP = 1. If data batch assignment information is sent in every other downlink subframe, then NA-MAP = 2. In this case ( ).

In frequency division duplex uplink hybrid automatic repeat request transmission and reception, the uplink data burst assignment information in downlink subframe number l of frame i shows that the transmission of the data burst begins in uplink subframe number m of frame j. When the data burst assignment information is transmitted in each downlink subframe (i.e., NA-MAP=1), the data burst assignment information shows that the data burst transmission begins in uplink subframe n, i.e., n=m. On the other hand, when the data allocation information is transmitted in every other downlink subframe (i.e., NA-MAP =2), the data batch assignment information in downlink subframe No. n or (1+n), that is, n=m or (1n+). Pertinent information shows that n or (1n+) is included in the data batch allocation information. In this application, N is given according to the relationship:

n=ceil(l+F/2) mod F.

The data batch described by the data batch assignment information can occupy one or more uplink subframes. Data batch interval transmission is signaled by NTT1 NTT1 is signaled by data batch allocation information.

A Hybrid Automatic Repeat reQuest (HARQ) for a data batch that begins transmission in uplink subframe m of frame i is sent in downlink (DL) subframe l of frame k. That is, data batch allocation information and a hybrid automatic redundant request reply are sent in subframes with the same parameter. According to the subframe and frame coefficients m and j, the frame coefficient k is determined as mentioned in Table (2).

The deviation of the uplink hybrid automatic repeat request can be calculated with a time processing called v and the deviation of the downlink hybrid automatic repeat request response called w mentioned in Table (2) by equations (2 and 4). The time-processed HARQ uplink deviation named v can be taken into account for batch transmission and retransmission when receiving data batch allocation information or a Hybrid Automatic Repeat reQuest (HARQ) response.

When an uplink data batch is retransmitted in an asynchronous hybrid automatic repeat request, the uplink data batch retransmission time is given by the position of the data batch allocation information and the retransmission indicator in the data batch allocation information at the same time, if a batch is retransmitted Uplink data In a synchronous hybrid automatic repeat request, retransmission occurs in the m subframe of the p frame. Referring to Table (2), the frame coefficient p is determined according to the subframe and frame coefficients L and K.

The time-processing uplink deviation of a hybrid auto-repeater called v refers to the time period between the transmission time of a downlink data batch allocation information or a downlink hybrid auto-repeat response and the transmission time of an uplink data batch, expressed as a number of frames. The uplink deviation of the Hybrid Automatic Repeat reQuest (HARQ) with a time processing named v is determined by taking into account that Gap1 is calculated by substituting the Transmission Time Interval (TTI) for data batch allocation information or Hybrid Automatic Repeat reQuest (HARQ) ) in a DownLink (DL) data burst transmission, NTT1 in Equation (2). The allocation information of a data batch or hybrid automated recursive request generally spans a single subframe.

In a downlink hybrid auto-repeater, the uplink deviation of a time-processing hybrid auto-repeater called v is determined so that Gap1' is the processing time Tx. For example, if Gap1' is the processing time Tx, then v = zero, while if Gap1' < the processing time Tx, then v = 1.

The deviation of the downlink hybrid automatic redundant called w refers to the time period between the completion of the transmission of an uplink data batch and the time for sending a downlink hybrid automatic redundant callback on an uplink data batch, expressed as a number of frames. The deviation of the downlink HDR response called w is determined by considering that Gap2' is calculated by substituting the uplink data burst transmission time interval (TTI) into the Transmission Time Interval (TTI) of the HHRD for the downlink HMR operation. The drop in equation (4).

In a downlink hybrid automated redundant, w is defined such that Gap2' is the processing time Tx. For example, if Gap2' is processing time Tx, then w = 0, while if Gap2' < processing time Tx, then w = 1.

As mentioned before, the skew of the uplink RAM with time processing, called v, and the skew of the downlink RAM reply, called w, are determined using the time-slot transition of the hybrid ARM process (interval transition of data batch or reply) and the signal processing capability of the system. (transmitter and receiver) in a Frequency Division Duplex (FDD) frame. Information regarding the signal processing capability can be predetermined or broadcast by the system. It can also be expected as another representational model in which predetermined values of w and v are performed in the system body information according to the system process diagram.

If the frame coefficients j, k, and p are N in Table No. (2), then the superframe coefficient S is increased by 1, and the frame coefficients j, k, and p are the values obtained by calculating the positive values of the equations mentioned in Table No. ( 2).

In Time Division Duplex mode, each frame includes Downlink (DL) subframes and Uplink subframes. According to an exemplary embodiment of the present invention, a link with more subframes is partitioned by a link with fewer subframes thereby transferring downlink subframes to uplink subframes at a given base. Each of the areas resulting from the link division includes one or more subframes and is transferred to one subframe of the link with fewer subframes.

That is, M subframes are divided into N space (N<M), and each subframe is in a vector relationship defined in accordance with the present invention. The carrier relationship will be described later.

Figure (5) is a diagram showing the timing structure of a downlink hybrid automatic repeat dialing process for Time Division Duplex 5:3 according to a representative embodiment of the present invention. The timing structure of the downlink hybrid automatic repeat dialing process is formed based on the time division dual frame structure shown in Figure (2).

Referring to Figure (5), a sender sends data batch assignment information and a downlink data batch in downlink subframe number l 500 of frame i. The receiver then sends a Hybrid Automatic Repeat reQuest (HARQ) on a downlink data burst in uplink subframe zero 510 of frame i. The sender retransmits the transmission of the data burst in the first downlink subframe 520 of frame (1+i), if the hybrid automatic redundant request response is a negative ack (NACK) signal. In DownLink (DL) subframe No. l 520, data batch assignment information indicating the transmission of a downlink data batch can also be transmitted. For the retransmitted data batch, the receiver sends a hybrid automatic redundant request reply in uplink subframe zero 530 of frame (1 +i).

While downlink subframes and uplink subframes have previously been described as having separate coefficients in the DL and uplink periods, respectively, it is possible to perform subframe coefficients sequentially within a frame. In this case, the parameter X of an uplink subframe is replaced by the parameter D+X of a subframe in a frame. D indicates the length of the DL period.

The preceding Hybrid Automatic Repeat reQuest (HARQ) process will be described more specifically by reference in Table 3 below. Table (3) shows the timing structure of a hybrid downlink automatic repeat dialing process for the downlink:uplink mode according to a representative embodiment of the present invention. D denotes the downlink slot length (i.e. the number of downlink subframes) and u denotes the uplink slot length (i.e. the number of uplink subframes).

Table 3 may be used to determine the transmission time for at least one assignment from an Information Element (IE) and an Advanced MAP (A-MAP) using data batch assignment information and a Hybrid Automatic Repeat reQuest (HARQ) subpacket. ) carries a data burst, an ACK (negative ack (Nack) signal), and a subpacket for retransmitting an ACK. However, it is understood that Table 3 should not be considered a limitation of the present invention.

In Table 3, D refers to the number of Downlink (DL) subframes per D frame, U refers to the number of Uplink subframes per uplink frame, and N refers to the number of frames per Superframe. If each superframe contains four subframes, then N = 4. F denotes the number of subframes per frame, so F=D+U, and i, j, and k denote the frame coefficients. l refers to the index of a DL subframe carrying the data batch allocation information, m refers to the index of a subframe in which a DL data batch begins to be transmitted, and n refers to the subframe parameter carrying the Hybrid Automated Recurring Request reply Automatic Repeat reQuest (HARQ) on DL data batch. In addition, z denotes the deflection of the downlink hybrid autorecurring request and uplink denotes the downlink deflection of the downlink hybrid autorepeater with time processing thus:

( , , , , , , and ).

NA-MAP indicates the transmission period of data batch allocation information. If data burst assignment information is transmitted in each DownLink (DL) subframe, then NA-MAP = 1 and l ranges from zero to D-1. If data batch allocation information is sent in every other DL subframe, then NA-MAP = 2. In this case ( ).

The parameter K is defined according to the relationship between D and U. For example, K is defined as Equation (7) or Equation (8) Depending on the system bandwidth, processing period and NA-MAP transmission period of data batch allocation information, Kc=k or Kf. Kc means a value calculated using the ceil() function, and Kf means a value calculated using the floor() function. How K is decided depends on the body of the system. Although k is generally Kf, Kc can be used under the conditions that F is an odd number and D<U/ NA-MAP.

. . . . . (6)

. . . . . (7)

If UD, then Kc and Kf are zeros or positive values, otherwise they are negative values. When F is an even number, the ceil() and floor() functions work in the same way, so Kc and Kf are identical. According to another embodiment, K can be determined as follows. If D<U then K=-ceil{(UD)/2} and if DU then K=floor{(DU)/2}.

In hybrid automatic downlink time-division duplexing, the assignment information of a DL data burst sent in a downlink branch frame number l of frame i shows that the transmission of the data burst begins in a DownLink (DL) subframe number m For frame i. When the data burst assignment information is transmitted in each downlink subframe (i.e. NA-MAP=1), the data burst assignment information shows that the transmission of the data burst begins in the downlink subframe, i.e. l=m. On the other hand, when the data assignment information is transmitted in every other downlink subframe (i.e. NA-MAP=2), the data batch assignment information in downlink subframe No. l or (1+l), that is, l=m or (1 + l). The relevant information shows that l or (1+l) is included in the data batch allocation information.

The data batch indicated by the data allocation information can occupy one or more downlink subframes.

A Hybrid Automatic Repeat reQuest (HARQ) is sent to a data batch that begins transmission in downlink subframe m of frame i in uplink subframe n of frame j. According to the downlink:uplink ratio (D:U), n can be transferred to the index of a subframe of one or more downlinks. If DU, each uplink subframe is transferred to one downlink subframe. On the other hand, if D>U, each uplink subframe is transferred to one or more downlink subframes. As defined in Table (3), the index of a subframe n is determined using K and m, and the index of frame j is determined using i and z. That is, Table (3) specifies a specific transmission relationship between the downlink subframe coefficients and the uplink subframe coefficients in one frame according to the uplink:downlink ratio. Table (1) shows that the D=U case is included in the DU case in addition to the DU case. Because K = zero if D = U. This document explains that the timing of a Hybrid Automatic Repeat reQuest (HARQ) in the D=U case is included in the DU case.

As mentioned before with reference to the downlink hybrid auto-repeat timing structure with frequency division duplex in Table (1), z denotes the downlink hybrid auto-repeat deviation. To provide sufficient Rx processing time, z is used to set the frame indexes of a Hybrid Automatic Repeat reQuest (HARQ). Because a Downlink (DL) subframe alternates with an uplink subframe in a frame along the time axis, the Gap3 drawn by Equation (8) is used to determine the downlink hybrid auto redundant deviation called z.

. . . . . (8)

Where MDATA refers to the number of subframes carrying data bursts, a refers to the index of a subframe a at which the transmission of the data burst begins, NTT1 refers to the transmission of the data burst interval, and b refers to the frame index The subcarrying a hybrid automated recursive request response to a data batch. Accordingly, MDATA=D, a=m and b=n, referring to Table (3).

In a dual downlink hybrid automatic redundant time division, the downlink hybrid automatic redundant deviation called z is set so that the Gap3 mentioned in Equation (8) is the processing time Rx. For example, if Gap3 is the processing time Rx, then z=0, while if Gap3 is the processing time Rx, then z=1.

When downlink data is retransmitted in an asynchronous hybrid automated repeat request, the retransmission of a downlink data batch is indicated by a retransmission indicator located in the data batch assignment information. At the same time, if a downlink data batch is retransmitted in a synchronous Hybrid Automatic Repeat reQuest (HARQ), the retransmission occurs in subframe m of frame k. Referring to Table (3), the frame coefficient k is determined by the frame coefficient carrying the Hybrid Automatic Repeat reQuest (HARQ) and the downlink deviation of the HARQ with a time processing called u. If the data batch assignment information shown is sent to retransmit a DownLink (DL) data batch, the retransmission is performed based on the data batch assignment information.

As mentioned before with reference to the frequency division duplex downlink hybrid auto-repeater timing structure in Table (1), u is the time-processed downlink hybrid auto-repeater deviation, determined using Gap4 calculated by equation (10). Gap4 is the time gap between the transmission time of a Hybrid Automatic Repeat reQuest (HARQ) and the start of data retransmission in Time Division Duplex mode.

. . . . . (9)

where MCRTL refers to the number of subframes carrying Hybrid Automatic Repeat reQuest (HARQ) responses, b refers to the subframe parameter carrying the Hybrid Automatic Repeat reQuest (HARQ), and a refers to the subframe index of a subframe in which transmission of the data burst begins after a Hybrid Automatic Repeat reQuest (HARQ). Hence, MCRTL=u, b=n, and a=m in Table 3.

In the dual downlink hybrid automatic redundant time division, the deviation of the hybrid automatic downlink downlink label is adjusted by processing time so that the Gap4 calculated by Equation (9) is the processing time Tx. For example, if Gap4 is processing time Tx, then u = zero. On the other hand, if Gap4 < processing time Tx=, then u = 1. If 1=u, this means that there is not enough time to process the transmission signal and thus the retransmission time of Hybrid Automatic Repeat reQuest is delayed by one frame. In Table 3, the frame coefficients j and k are from the total number N of frames for each superframe, the superframe coefficient is increased by 1, and the frame coefficients j and k are the values obtained by calculating the positive value of the operations shown in Table No. (3).

It may also be contemplated as another representative embodiment of the present invention that the downlink hybrid auto-repeater deviation named z and the time-processed hybrid auto-repeater downlink deflection designated u are determined according to the downlink: uplink subframe transfer relationship, and/or the transmission time period. Time Interval (TTI) of a Hybrid Automatic Repeat reQuest (HARQ) process, and/or the ability of the system to process the signal.

Figure (6) is a diagram showing the timing structure of a hybrid automatic repeat request process for sending a data batch to the uplink in a Time Division Duplex frame according to a representative embodiment of the invention.

Referring to Figure (6), after receiving data batch assignment information in downlink subframe number li, a sender sends an uplink data batch in uplink subframe number zero 610 of frame i. A receiver sends an automatic hybrid redundant request on an uplink data batch in a first downlink subframe 620 of a (1+i) frame in the event of an error in the received data batch.

If the Hybrid Automatic Repeat reQuest (HARQ) is a negative ack (NACK) signal, the sender sends a data burst in uplink subframe zero 630 of the (1+i) frame.

If the downlink subframe 620 carrying the data burst assignment information indicates an uplink retransmission of the data burst, then the uplink transmission of the data burst is performed in accordance with the data burst assignment information.

While it was previously described that DownLink (DL) subframes and uplink subframes have separate transactions in periods, DownLink (DL) and uplink subframes respectively, downlink and uplink subframes have separate transactions in periods. A frame. In this case, the parameter of an uplink subframe called x is replaced by the index of a subframe D+x in a frame. D indicates the downlink period length.

Table (4) shows the timing structure of a downlink hybrid automatic repeat dialing process in Time Division Duplex mode according to a representative embodiment of the present invention. Table (4) may be used to determine the time for assigning an advanced information element to at least one transmission using data batch assignment information, a hybrid automatic repeating request subpacket carrying a data batch, a hybrid automatic repeating request response or a negative ack (NACK) signal, and a packet. Sub to retransmit a hybrid automatic recursive request. However, it is understood that Table 4 should not be considered a limitation of the present invention.

In Table No. (4), D refers to the number of Downlink (DL) subframes per downlink frame, U refers to the number of uplink subframes per uplink frame, and K is a parameter defined in equations (6,7). ), according to the relationship between D and u and N denotes the number of frames per superframe. If each superframe has four subframes, then N = 4, and i, j, k, and p denote the frame coefficients. L denotes the index of a downlink subframe carrying data burst assignment information, m denotes the index of a subframe at which a data burst begins to be transmitted, w denotes downlink hybrid automatic redundant response deviation, and v denotes To deviate the uplink of a hybrid automatic repetitive request with time processing, thus:

( , , , , , , and ).

NA-MAP is the transmission period of data batch allocation information. If data batch assignment information is transmitted in each downlink subframe, then NA-MAP = 1 and l varies between zero and D-1. If data batch assignment information is sent in every other DownLink (DL) subframe, NA-MAP = 2. In this case ( ).

In time-splitting duplexing of hybrid downlink automatic redundancy, the assignment information for an uplink data batch sent in DownLink (DL) subframe number l of frame i indicates that the transmission of the batch begins in uplink subframe number m of frame j. Depending on the downlink:uplink (D:U) ratio and NA-MAP allocation information period, m can be transferred to one or more DownLink (DL) subframes. If ( ) i.e. if the number of downlink subframes carrying downlink control information (data batch allocation information or Hybrid Automatic Repeat reQuest (HARQ) responses) is the number of uplink subframes, then each uplink subframe is transmitted To one or more downlink subframes. On the other hand, if (ceil(D/NA-MAP)<U), that is, if the number of downlink subframes carrying downlink control information (data batch allocation information or Hybrid Automatic Repeat reQuest (HARQ)) < The number of uplink subframes, each downlink subframe is transferred to one or more uplink subframes.

If the number of downlink subframes carrying data burst assignment information is the number of uplink subframes ceil(D/NA-MAP)≥U, then a data burst transmission in an uplink subframe can be represented by one or more downlink subframes. That is, if l < k, the data burst assignment information in downlink subframe number l shows that the transmission of the data burst begins in subframe number zero. If kl and u+k, the data burst assignment information is in the downlink subframe number l, and it turns out that the transmission of the data burst begins in the uplink subframe number (lk). If u+kl, the data burst assignment information in the DownLink (DL) subframe l shows that the transmission of the data burst begins in the uplink (Ul) subframe.

On the other hand, if the number of downlink subframes carrying data burst assignment information < the number of uplink subframes (ceil(D/NA-MAP) < U), the data burst assignment information in a downlink subframe can show burst transmissions Data in one or more uplink subframes. For example, data batch assignment information in downlink subframe number zero shows data batch transmissions in uplink subframe numbers zero through (l-K+NA-MAP-1). Pertinent information related to clarification is sent in the data batch customization information.

If data batch assignment information is transmitted in only one downlink subframe (ceil(D/NA-MAP)=1), the downlink subframe shows data batch transmissions in all uplink subframes. The Transmission Time Interval (TTI) of a data batch can be indicated by the data batch assignment information and the frame parameter j is specified using i and v.

As mentioned by referring to the frequency-division duplex uplink HRD timing structure in Table (2), v refers to the uplink deviation of the HRD uplink with time processing, and w refers to the downlink HMRD response deviation. The uplink deviation Hybrid Automatic Repeat reQuest (HARQ) Tx named v is used for the transmission of the data burst after receiving the HARQ allocation information. . As mentioned before, the uplink bias of a hybrid automated redundant request with time processing named v is used to adjust the frame parameter carrying the data batch to ensure sufficient Tx processing time.

In time-division duplex downlink auto-repeat, the uplink deflection of the downlink auto-repeat is determined by a time processing called v using Gap4' which is calculated by exposing a number of D downlink (DL) subframes carrying control information such as assignment information A batch or Hybrid Automatic Repeat reQuest (HARQ) for MCTCM, and exposure by parameter l of the subframe carrying data batch assignment information or a Hybrid Automatic Repeat reQuest (HARQ) for, And the exposure by factor m of the subframe carrying the first transmission or retransmission data batch of a, in equation (9).

If > Gap4' is the processing time Tx required to send a transmission of the data burst after receiving a Hybrid Automatic Repeat reQuest (HARQ), then l = v, otherwise v = zero.

In downlink Hybrid Automatic Repeat reQuest (HARQ), to set the transmission time of Hybrid Automatic Repeat reQuest (HARQ) after receiving a data batch, the downlink HARQ deviation named w is determined using Gap3' which is defined by the MDAT definition. As the number U of subframes carrying data bursts in Equation (8).

If Gap3' is the processing time Rx required to send a hybrid automatic redundant request after an uplink data burst is received, then w = 1 otherwise w = 0.

A hybrid automatic redundant request reply to a data burst sent in an uplink subframe m of frame j is transmitted in a downlink subframe l of frame k. That is, data batch allocation information and a hybrid automatic redundant request are sent in subframes with the same parameter. In this order k is defined by j.

When an uplink data batch is retransmitted in an asynchronous Hybrid Automatic Repeat reQuest (HARQ), the uplink data batch retransmission time is indicated by a retransmission indicator in the data batch assignment information. At the same time, if an uplink data batch is retransmitted in a synchronous hybrid automatic repeat request, the retransmission occurs in subframe m of frame p. Referring to Table (4), the frame parameter P is determined by the uplink deflection of the hybrid automatic repeating request with a time processing called v and the factor k of the frame carrying the hybrid automatic repeating request. If the coefficients j, k, and p are the total number N of frames for each superframe, then the superframe coefficient S is increased by 1 and the frame coefficients j, k, and p are the values obtained by calculating the typical operations shown in Table (4).

While it has previously been described that the timing of a hybrid autorecurring request is determined using Table Equations (1-4), the timing of a hybrid autorecurring request can be determined by storing a table with result values according to Table Equations (1-4) corresponding to all possible input values. (i.e. the number of uplink/downlink subframes, index of a subframe, processing time, and so on) to a sender or receiver and read the required result values from the table.

Calculating hybrid automated redundant callback and Tx deviations

Representative models for calculating HDR response deviations called w and z and time-processing HDR deviations called v and u will be described hereafter.

Hybrid auto-repeat reply deviations called w and z and time-processing hybrid auto-repeat deviations called v and u can be determined according to the transmission relationship between DownLink (DL) subframes and uplink subframes, and the transmission time interval of the hybrid auto-repeat process ( transmission interval of a data burst or reply), and/or the ability of the system to process the signal (sender and/or receiver). In another representative embodiment of the present invention, Hybrid Automatic Repeat reQuest (HARQ) deviations can be predetermined and broadcast by the system, rather than being calculated using prior information. HARQ process related deviations are defined as follows.

At least one HARQ deviation labeled z and a Tx deviation labeled u for a frequency division duplex downlink hybrid auto-repeated dialing operation are calculated by

. . . . . (10

Where Rx_Time1 Rx denotes the processing time Rx of a data batch, determined by the processing power of the receiver, and Tx_Time1 denotes the processing time Tx of a data batch, determined by the processing power of the sender. Rx_Time1 and Tx_Time1 can collectively be referred to as the time of a data batch.

Rx processing of a data batch includes, for example, demodulation processing, Multiple Input Multiple Output (MIMO) Rx decoding. The Tx processing of a data batch includes, for example, decoding, embedding, and multi-input and multi-output MIMO Tx processing. In a downlink hybrid automatic repeat request the receiver is generally a Mobile Station (MS) and the sender is a Base Station (BS). In this application, the hybrid autorepeat interval is assumed to be a single subframe and the transmission of the data burst transmission time interval is represented as NTT1.

At least one of the hybrid auto redundant callback deviations designated w and a time-processed hybrid autoredundling deviation designated v are calculated on a frequency division duplex uplink hybrid autoredialing process by:

. . . . . (11)

Where Rx-Time2 refers to the processing time Rx of the data batch, determined by the processing capacity of the receiver, and Tx-Time2 refers to the processing time Tx of the uplink data batch, determined by the processing power of the sender. Rx-Time2 and Tx-Time2 can collectively be referred to as data burst time. In a downlink hybrid automatic repeat request, the receiver is generally a Base Station (BS) and the sender is an MS.

At least one of the hybrid redundant callback deviations labeled z and a time-processed hybrid redundant deviation labeled u on the downlink hybrid redundant time-splitting duplex process are calculated by:

. . . . . (12)

Where Tx-Time3 and Tx-Time3 denote the Rx and Tx processing times of a data batch, respectively. Rx-Time3 and Tx-Time3 can be collectively referred to as data batch processing time.

At least one of the hybrid auto-repeat callback deviation named W and the time-processing hybrid auto-repeater deviation named v on the downlink hybrid auto-repeat duplex process can be calculated by:

. . . . . (13)

Where Rx-Time4 and Tx-Time4 refer to the Rx and Tx processing times of an uplink data batch, respectively. Rx-Time4 and Tx-Time4 can be collectively referred to as data batch processing time.

In a synchronous hybrid auto-repeat, the processing time Tx for the downlink hybrid auto-repeat operation differs for the first transmission and retransmission. That is, Tx-Time2 in Equation (12) and Tx-Time4 in Equation (14) can be replaced by Tx-Time-New Tx and Tx-Time Re Tx according to whether the data batch was sent first or Tx-Time was retransmitted. -New Tx represents the processing time Tx for the first transmission of a data batch, and Tx-Time-Re Tx represents the processing time Rx for re-sending a data batch. As mentioned before, although the first transmission of the data batch is encoded according to the data batch assignment information, the data batch that is initiated to be retransmitted can be encoded by a negative ack (NACK) signal based on the first transmission of the encoded data batch. Thus, a deviation is set for a hybrid automated recurring request with time processing, taking into account different Tx processing times for the first transmission and retransmission.

Depending on when retransmission is initiated, the processing time Tx for transmission of the data burst may be Tx_Time Re Tx1 or Tx_Time Re Tx2.

Retransmission can be initiated in two ways: in the first method only a negative ack (Nack) signal is sent, and in the second method both a negative receive signal and assignment information are sent for retransmission. Tx_Time Re Tx 1 is used in the former case and Tx_Time Re Tx2 is used in the later case.

Likewise, the UpLink (UL) deviations for a hybrid automatic repeat request can be set with time processing mentioned in Tables (2, 4) and Equations (11, 13) separately as Vnew and VRxTx according to the processing time Tx of the first transmission or retransmission Vnew. vRxTx is the uplink deviation of a hybrid automated repeat request with a time processing for the first transmission of a data batch, taking into account the processing time Tx, and Tx_Time New Tx, and vRxTx is the uplink deviation of a hybrid automatic recurring request with a time processing for the retransmission of a data batch, taking into account Processing Time Tx, and Tx_Time Re Tx.

Mode support technology inherited from prior art

A wireless mobile communication system using the Institute of Electrical and Electronics Engineers (IEEE) advanced 802.16m air interface can be co-existed with an underlying wireless mobile communication system (IEEC 802.16e), by using Specific frame deflection in a superior frame structure. Specifically, each 16m frame includes a frame diffraction along with DownLink (DL) subframes and UpLink (UL) subframes in order to equalize the contrast from the 16e frame. In this case, the timing structures of the downlink hybrid automatic repeating process are formed based on the timing structures of the hybrid automatic repeating request process mentioned in Tables (3 and 4) according to the downlink:uplink response ratio for a period in which a network node and a mobile station operate ( MS) in IEEE 802.16m mode.

The downlink subframe to uplink subframe transfer relationship is determined according to the downlink:uplink ratio for a period during which a network node and a Mobile Station (MS) operate in IEEE802.16m mode. In other words, the parameters and numbers of subframes in the transmission periods of a hybrid automatic repeat request process are determined according to the uplink:downlink ratio. However, due to the co-existence of IEEE 802.16e and 802.16m mode in a single frame, the frame coefficients are not entered according to the downlink:uplink ratio for the 16m mode period but according to the total downlink:uplink ratio for a Time Division Duplex frame system. .

Let us denote the number of downlink subframes and the number of UpLink (UL) subframes in a Time Division Duplex frame system by D' and U' respectively. The subframe parameters are numbered l, m' and n' according to the downlink ratio. : The uplink of a Time Division Duplex system, i.e. D:U. Let us also denote the number of downlink subframes and the number of UpLink (UL) subframes in a 16m mode period by D and U respectively. The subframe parameters l, m and n are then numbered according to the downlink:uplink ratio for the 16m mode period, D:U.

For the 16m mode period other than the 16e mode latency period, the timings for the hybrid automatic redundant request process follow the schedule (3, 4). However, the parameters of frames i, j, and k are determined according to the skew of the hybrid autorequest response labeled Z or W, and the skew of the hybrid autorequest with time processing is numbered u or v using subframe parameters l', m', and n' according to D': U'.

Figure (7) shows the timing structure of a hybrid automatic redundant dialing process for sending a DownLink (DL) data batch in 5:3 Time Division Duplex mode in the case of the co-existence of two different systems according to a representative embodiment of the present invention.

Referring to Figure (7), two downlink subframes and a frequency division mixing (FDM) zone are stacked for the prior art system support mode (i.e. legacy technology support mode) and the parameters of the subframes in the remaining connection slots are renumbered except for those allocated To place a reinforcing technique inherited from the prior art. With a larger definition, there are downlink subframes from zero to fourth. In a full time division duplex frame system. Therefore, the second, third and fourth downlink subframes are renumbered as 0, 1 and 2, respectively in the 16m mode period. The UpLink (UL) period is shared with the FDM downlink period, and the 16m mode period occupies a full uplink period. Thus the mode 16m frame actually contains three downlink subframes and three uplink subframes.

Referring to Figure (7), since D = 3, U = 3, and K = zero, D' = 5 and U' = 3. In sending a data batch, time-division duplex, automatic hybrid downlink repeating request, information is sent Allocate a data batch and a data batch in downlink subframe number zero of frame i. A hybrid automatic redundant request reply is sent to the data burst in uplink subframe number zero of frame i. A hybrid auto redundant retransmission occurs in the DownLink (DL) subframe of frame (1+ i) and a hybrid auto redundancy reply to the transmission of the data burst is sent in the zero uplink subframe of frame (i). 1+i). In the case shown in Figure (7), both the processing times Tx and Rx are considered in two subframes.

Figure (8) shows the timing structure of a Hybrid Automatic Repeat reQuest (HARQ) process for sending an UpLink (UL) data batch in 5:3 Time Division Duplex mode in the case of the co-existence of two different systems according to a representative embodiment of the invention. Present.

Referring to Figure (8), since D = 3 and U = 3 according to the frame structure in Figure (7), K = zero. In a hybrid downlink automatic redundant time-division duplex data burst transmission, the data burst assignment information is sent in the zero downlink subframe of frame i, and an UpLink (UL) data burst is sent in the zero uplink subframe of frame i according to For data batch customization information. A hybrid automatic redundant is sent on an uplink data burst in the zero downlink subframe of frame (1+i) and a retransmission of an uplink data burst occurs in the zero downlink subframe of frame (1+i). In downlink subframe number zero, data batch assignment information indicating the transmission of a link data batch can be transmitted. In the case shown in Figure (8), both the processing times Tx and Rx are considered two frames.

The sources used in the IEEE 802.136e wireless communication system are allocated a period corresponding to a frame deviation in Figures (7, 8).

The timing structures for the hybrid automatic repeating request process proposed in Tables (1-4) are determined according to the index of a subframe carrying the data burst allocation information or to the parameter of the subframe in which the transmission of the data burst begins, regardless of the transmission of the data burst. Transmission Time Interval (TTI) Data batch. Hence, by transmitting a hybrid automatic redundant periodically in a specific subframe in a synchronous hybrid redundant, the receiver saves energy that would otherwise be consumed monitoring the reception of a hybrid automatic redundant, effectively enhancing co-locality/co-presence (CLC). .

Long Transmission Time Interval (TTI):

In another example embodiment of the present invention, when a data burst occupies two or more subframes, i.e. when a long-interval transmission is used, the timing of a hybrid automatic repeat request response can be determined according to the index of a subframe in which the transmission of the data burst ends. data burst, instead of the index of a subframe in which the transmission of the data burst begins, in order to carry the early ACKnowledgment (ACK) timing for the hybrid automatic redundant request timing structures mentioned in Tables (1-4). This timing decision can be used as an early ACKnowledgment (ACK) in a typically asynchronous hybrid automated redundant request.

The timing of the Hybrid Automatic Repeat reQuest (HARQ) response defined in Table (1) is set as follows. The parameters of the subframe and the frame carrying the hybrid automatic redundant request are determined based on the parameter m'(=m+NTT1-1) of the last subframe of the data burst interval transition instead of the parameter m of the first subframe of the data burst interval transition.

Figure (9) shows the timing structure of a hybrid automatic redundant dialing process for transmitting a DownLink (DL) data batch in Frequency Division Duplex (FDD) frame mode according to another representative embodiment of the present invention. In this application it is assumed that NTT1 = 4 and F = 8, the Tx and Rx processing times are each three subframes or less, the downlink auto redundant response deviation labeled z = zero, and the hybrid auto redundant downlink skew With a time processing labeled u = zero.

Referring to Figure (9), the data batch assignment information sent in the first DownLink (DL) subframe of frame i shows that a downlink data batch is sent in the TT1900 first to fourth D subframes in frame i. An automatic hybrid redundant request is sent on a downlink data burst in link subframe number zero (910) of frame (1+i) transferred to the fourth downlink subframe of frame i, where transmission of the data burst downlink ends. That is, n=0 (=ceil(1+4-1+4) mod 8) and j=i+1 (=(i+floor(ceil(1+4-1+4)/8) mod 4)) ). In a synchronous hybrid automatic repeat request, the transmission of the data burst 920 begins at the same subframe location as the previous transmission of the data burst, i.e., in the first downlink subframe of frame (i+2).

As mentioned before, the response timings for a hybrid automatic redundant request can be determined according to the parameter m' of one or more last subframes carrying the data batch, instead of the parameter m of the first subframe in Tables (1 and 2). Similarly, in the timing structure of a hybrid auto-repeat operation in Time Division Duplex mode, the timing of the hybrid auto-repeat reply can be determined by setting the parameter m (=m+NTTI-1) of the last subframe carrying the data burst, instead of Parameter m for the first subframe of the data batch, in Table 3, in order to obtain an early ACKnowledgment (ACK) timing.

Figure (10) shows the timing structure of a Hybrid Automatic Repeat reQuest (HARQ) process for sending a downlink data batch in time division duplex mode according to another representative embodiment of the present invention. This application assumes that NT11 = 4, D = 4, and u = 4 and that the Tx and Rx processing times are each three subframes or less, and

k = zero and z = zero.

Referring to Figure (10), the assignment information for the data batch sent in the first DownLink (DL) subframe of frame i shows that sending a downlink data batch in a 1000 time interval transmission of the zero to third downlink subframe in frame i. A hybrid automatic redundant request reply is sent to the downlink data burst in the third link subframe 1010 of frame i transmitted to the third downlink subframe of frame i in accordance with Table (3). That is, n=0 (=3-0) and j=i (=(i+0) mod 4). In a synchronous hybrid automatic repeat request, the transmission of the data burst 1020 begins at the same subframe location as the previous transmission of the data burst, i.e., from the subframe and downlink number zero (i+2).

However, the HDR reply is timed differently depending on the downlink:uplink ratio and processing time Tx/Rx in a dual process timing structure for the Transmission Time Interval (TTI). . A hybrid auto redundant response timing description will be made for a long interval transmission (five subframes) in a 5:3 duplex downlink hybrid auto redundant operation, if the processing time Tx/Rx is Three subframes and a time slot transmission covering the entire downlink period, for example.

If the hybrid auto redundant is timed according to the start of the transmission of the data burst, the hybrid auto redundant is sent to the data burst that began transmission in the subframe. Downlink zero in the subframe and uplink zero to the next frame. . On the other hand, if the timing of the hybrid automatic redundant callback is determined according to the completion of the transmission of the data burst, then the hybrid automatic redundant callback is sent to the data burst that has finished transmitting in the fourth downlink subframe in the third uplink subframe of the frame. the next. Thus, if a long-interval transmission is used in 5:3 duplex downlink hybrid auto-repeat time division, the hybrid auto-repeat response timing for the long-interval transmission is provided based on the beginning of the transmission of the data burst, rather than From relying on the end of transmission of the data burst

Hybrid Automatic Repeat reQuest (HARQ) timing for a long-slot transmission of four subframes in a 4:4 duplex downlink HARQ will be described as another example.

If the hybrid auto redundant is timed according to the start of the transmission of the data burst, the hybrid auto redundant is sent to the data burst that begins transmission in the DownLink (DL) subframe, number zero in the uplink subframe. Zero for the next frame. On the other hand, if the hybrid autorepeat is timed according to the end of the transmission of the data burst, then the hybrid autorepeat is sent to the data burst that ends its transmission in the fourth DownLink (DL) subframe in the subframe. The third uplink of the next frame, other than 5:3 duplex automatic hybrid downlink time division redundant, is 4: 4 Duplex time-division downlink hybrid auto-repeat provides early hybrid auto-repeat timing for long-interval transmission based on the end of the transmission of the data burst, instead of relying on the start of the transmission of the data burst.

Accordingly, a suitable hybrid auto-repeat timing structure is selected according to the downlink:uplink ratio and processing time Tx/Rx in the representative embodiment of the present invention. More specifically, when a decision is made about when to respond to a hybrid auto-recurring request in Table (1-4), the decision is made based on the parameter m (=m+NTTI-1) of one or more last subframes carrying a data batch rather than the parameter m for the first one or more subframes. Information regarding the timing structure of the selected hybrid automated repeat request process may be signaled, for example as system information on a common control channel.

Hybrid Automatic Repeat reQuest (HARQ) change response and Tx deviations Other representative examples of timing structures for the downlink Hybrid Automatic Repeat reQuest and downlink Hybrid Automatic Repeat reQuest in Time Division Duplex mode will be described later. . More specifically, varying the skew of a hybrid automatic redundant request and a skew of a hybrid automatic redundant request with time processing according to the location of the subframe carrying a downlink data batch or an uplink data batch will be described.

Figures (11a, 11b) show the timing structures of a hybrid automated recurring request process when NA-MAP=1 and D+U=8.

Figure (11a) shows the timing structure of a hybrid automatic recurring request process in the case that D:U = 5:3 and the batch interval transmission is one frame. Referring to Figure (11a), when the processing time Tx/Rx is two subframes, the deviation of Tx/hybrid automatic redundant request is zero. That is, since each DownLink (DL) subframe transmission can be processed completely within two subframes (because Gap3 and Gap4 are transitive 2), the relevant uplink transmission occurs in the next uplink slot without time delay. Likewise, the transmission of each uplink subframe can be processed exactly within two subframes (because Gap3 and Gap4 are transitive 2) so that the relevant downlink transmission occurs in the next downlink slot without time delay.

However, if the processing time Tx/Rx is three subframes, the processing time for the uplink automatic hybrid repeat request related to the fourth downlink subframe is delayed by one frame. This is because although it takes three subframes to process the transmission of the fourth downlink subframe, it is difficult to perform an uplink transmission within two subframes (=5-4-1+2) as the period of the corresponding second subframe. Accordingly, the transmission of an uplink in the second uplink subframe corresponding to the fourth downlink subframe is delayed by one frame and thus occurs in the next (1+i) frame.

Figure (11b) shows the timing structure of a Hybrid Automatic Repeat reQuest (HARQ) process when D:U = 5:3 and the batch interval transition is a single subframe. Referring to Figure (11b), when the processing time Tx/Rx is two subframes, the deviation of Tx/Hybrid Automatic Recurring Request is zero. However, if the processing time Tx/Rx is three subframes, the Gap =3-0-1-0=2.

Therefore, the processing time of a hybrid automated uplink repeat request in uplink subframe zero related to DownLink (DL) subframe zero is delayed by one frame. Since Gap=5-4-1+2=2, the downlink transmission timing in the second DL subframe relative to the fourth uplink subframe is delayed by one frame. This is because each gap has processing time Tx or processing time Rx.

Figures (12a, 12b) show the timing structures of a hybrid automated recurring request process when D+U=7.

Figure (12a) shows the timing structure of a hybrid automated repeat request process in a situation where D:U = 4:3, NA-MAP = 1 and the batch interval transition is one subframe. Referring to Figure (12a), when the Tx/Rx processing lift is two subframes, the deviation of Tx/hybrid automatic redundant request is zero. If the Tx/Rx processing time is three subframes, the processing time for the uplink automatic repeat request is delayed for subframe #2 corresponding to the third downlink subframe with a frame rate of now Gap=4-3-1+2=2 .

Figure (12b) shows the timing structure of a hybrid automatic redundant request process in a situation where D:U = 3:4, NA-MAP = 1 and the Transmission Time Interval (TTI) is one subframe. When D+U is an odd number and U>D, Kc(=-1) is used based on ceil(). Referring to Figure (12b), because NA-MAP = 2, DownLink (DL) control information is sent in the zero and second downlink subframes. When the processing time Tx/Rx is two subframes, the deviation of Tx/hybrid redundant request is zero. However, if the Tx/Rx processing time is three subframes, the processing time for a hybrid automatic repetitive request for the uplink of subframe uplink number zero related to downlink subframe number 3 is delayed by one frame.

Figures (13a, 13b) show the timing structures of a hybrid automatic recurring request process when:

NA-MAP=1 and D+U=6.

Figure (13a) shows the timing structure of a hybrid automatic recurring request process in the case that D: U= 4 : 2 and the batch interval transition is one subframe. Referring to Figure (13a), when the processing time Tx/Rx is two subframes, the processing time for an uplink automatic hybrid repetitive request related to a third DL subframe is delayed by one frame. If the processing time Tx/Rx is three subframes, the HARQ DL Tx associated with uplink subframe number zero is delayed by one frame, and the processing time timings for an uplink hybrid auto-repeated request and the related HARQ DL Tx are delayed With two downlink subframes, the first and second, at a single frame rate.

In addition, the processing time for an automatic hybrid uplink repeat request related to downlink frame 3 is delayed by one frame.

Figure (13b) shows the timing structure of a hybrid automated recurring request process in a situation where D:U=3:3 and the Transmission Time Interval (TTI) batch is one subframe. Referring to Figure (13b), when the processing time Tx/Rx is two subframes, the deviation of Tx/Hybrid Automatic Recurring Request is zero. However, if the processing time Tx/Rx is three subframes The Tx deviation/hybrid redundant is 1, which means it is delayed by a frame rate.

Relay structure:

The timing architectures for a Hybrid Automatic Repeat reQuest (HARQ) process in a wireless mobile communication system that supports a relay architecture will now be described.

When supporting a relay structure, the Base Station (BS) and Mobile Station (MS) communicate with each other directly or via at least one transmit zone relay station. Transmitter relay stations are divided between a base station and a portable station into single-hop transmit zone relay stations and double-hop transmit zone relay stations. Each relay station includes a controller for timing a hybrid automatic repeating request with time processing according to the frame structure and timing of the hybrid automatic repeating request process, which will be described later, and at least one sender/receiver to send and receive data batch allocation information, data batch, and repeating request response timings. Hybrid automatic controlled by console. Data transmission represents data transmission between a Base Station (BS) and transmit zone Relay Stations or data transmission between transmit zone relay stations and a Mobile Station (MS).

In an exemplary embodiment of the present invention, the timing architecture of a hybrid automated redundant dialing process for a 16m relay station and a Mobile Station (MS) mode will be described.

Figure (14) shows a frame structure for a wireless mobile communication system that supports a relay structure according to a representative embodiment of the present invention.

Referring to Figure 14, the Base Station (BS) frame 1410 includes at least one downlink access zone 1412 transmitted from a direct base station to a Mobile Station (MS) and a downlink transmission zone 1414 transmitted From a base station to a portable station or relay stations transmit zone, a receive zone network coding receive zone 1416, an uplink access zone 1418 received from a portable station, and an uplink receive zone 1420 received from a mobile station Or relay stations. A gap 1422 is inserted between Tx regions 1412 and 1414 and Rx regions 1416, 1418 and 1420 to send it to the reception transitioning. The frame of single-hop relay stations includes a DownLink (DL) access zone 1432 transmitted to a portable station, a DL transmit zone 1434 transmitted to a portable station or pair-hop relay stations, and a receive zone downlink 1444 received from transmit zone pair-hop relay stations. or a Base Station (BS), a netcode transmit zone 1438, an uplink receive zone 1440 received from a Mobile Station (MS) or transmit zone = pair hopping, and an uplink transmit zone 1442 sent to Single hop relay stations or base station. Gaps 1444, 1446, and 1448 are intercalated between Tx region 1434 and Rx region 1436, between Rx region 1436 and Tx region 1438, and between Rx region 1440 and Tx region 1442 for transmission and reception. The frame of even-hop relay stations 1450 includes a downlink access zone 1452 sent to a Mobile Station (MS), a receive zone downlink 1454 received from odd-hop relay stations, and a DL transmit zone 1456 sent to a Mobile Station (MS). MS) or single hop relay stations, a network coding receive zone receive zone 1458, an uplink transmit zone 1460 sent to single hop relay stations, and an uplink receive zone 1462 received from a mobile station or relay stations Individual jump. Gaps 1464, 1466, 1468, and 1470 are inserted between the Tx region 1452 and the Rx region 1454 and between the Tx region 1456, and between the Tx region 1456 and the Rx region 1458, and between the Tx region 1460 and the Rx region 1462, for transmission and reception.

As mentioned before, in the Hybrid Automatic Repeat reQuest (HARQ) timing structure for areas where at least one transmit zone is connected to a Mobile Station (MS), a downlink subframe transfer relationship is defined: Uplink according to subframe parameters according to downlink ratio: Uplink for areas where at least one transmit zone relay station communicates with a Mobile Station (MS) within a corresponding relay station frame and the frame parameters are determined according to the sub-frame parameters, as in the hybrid automatic redundant dialing process referred to before for technology support mode Inherited from previous art.

Figures 15a and 15b show transmit zone relay station frame structures according to representative embodiments of the present invention. In Figures (15a, 15b) a Time Division Duplex frame has a downlink:uplink ratio = 4:4 (D':U'=4:4) and the network coding Tx/Rx regions are not shown.

Referring to Figure (15a) in the I-frame used for single-hop relay stations, single-hop Relay Stations (RSs) send DownLink (DL) subframes zero, first, and second to a Mobile Station (MS) or relay stations transmit zone is lower layer, receiving another downlink subframe from the Base Station (BS).

Single hop transmit zone relay stations receive the zero and first uplink subframes from a mobile station and transmit the other two uplink subframes to higher layer transmit zone relay stations or a base station.

Referring to Figure (15b), in the i-frame used for single-hop transmit zone relay stations, even-hop relay stations send downlink subframe number zero at the beginning and downlink subframe number one at the end of a downlink period to a mobile station. Station (MS) and receives the middle two downlink frames from single-hop relay stations at a higher layer. Even-hop relay stations receive two uplink frames zero and first at the end of an uplink period from a portable station and send the other two uplink subframes at the beginning of Uplink period to higher layer non-hopping relay stations.

Figures (16a, 16b) show timing structures for a Hybrid Automatic Repeat reQuest (HARQ) process for single hop transmit zone relay stations according to representative embodiments of the present invention. In Figures (16a, 16b), D: U =3:2.

Figure (16a) shows the timing structure of a hybrid automatic recurring request process that takes Kf into account. Referring to Figure (16a), the processing time of a hybrid automatic uplink repeat request corresponding to the second DownLink (DL) subframe is delayed by one frame.

Figure (16b) shows the timing structure of a hybrid automatic recurring request process that takes Kf into account. Referring to Figure (16b), each uplink HAR processing time timing corresponding to the first and second HAR subframes is delayed by one frame.

Figure (17) shows the timing structure of a hybrid automatic repeat request process for transmit zone pair-hopping relay stations according to a representative embodiment of the present invention. In Figure (17) it is D: U = 2: 2. As can be seen from Figure (17), the HARQ DL Tx timing corresponding to uplink subframe number zero is delayed by one frame.

As mentioned before, the value of K may need to be chosen according to the downlink:uplink ratio and Tx/Rx processing time in order to provide early hybrid auto-repeat timing.

The system operator selects an appropriate HRD timing structure and k value according to system configuration information such as downlink:uplink ratio and Tx/Rx processing time, and the system configuration information is transmitted on a common downlink control channel.

Hybrid Automatic Repeat reQuest (HARQ) timing structures for long interval transition.

Hybrid automatic redundant dial timing structures based on long Transmission Time Interval (TTI) assignment information will be described later with reference to Tables 3 and 4.

In a downlink Hybrid Automatic Repeat reQuest (HARQ), if a data batch assignment information is transmitted that shows a long-slot transmission is being transmitted in a specified downlink subframe and the long-slot transmission is being transmitted in a DownLink subframe (DL) Zero for the next frame. A hybrid automatic redundant request response is sent on a long Transmission Time Interval (TTI) transmission in the transmitted uplink subframe of the downlink subframe (i.e., the carrier of the data batch allocation information) of the next frame. In a downlink auto-repeat request, if a long time interval (TTI) transmission indicated by data batch assignment information transmitted in a specific downlink subframe is not available in the same frame, a long TTI transmission is transmitted. For an uplink data batch in an uplink subframe, there is uplink number zero for the next frame, and an automatic hybrid redundant request reply is sent to the uplink data batch in the downlink subframes that have the same parameter in the downlink subframe (i.e., the carrier of the batch assignment information data) for the next frame. The frame parameters are determined using the time-division double deviation of the previous hybrid automatic repeating request and the deviation of the hybrid automatic repeating request response. For example, when the assignment information of a data burst transmitted in subframe l (l is not equal to zero) shows that transmission of the data burst = long TTI downlink takes the entire downlink period (D=NTT1 ), and the batch transmission begins at zero downlink subframe. However, if the data burst assignment information on a downlink subframe number l, and l is zero, shows a long TTI transmission, then the transmission of the data burst is not sent downlink in the same frame, and the assignment information A data batch that shows a long interval transmission being sent in the next frame.

Referring to Table (3), the information for assigning a data burst of hybrid automatic redundancy to the downlink transmitted in subframe downlink number l of frame i shows the transmission of the data burst in subframe downlink number m using NA-MAP. However, in the case of a long TTI transmission, the data burst transmission is determined according to the index of a downlink subframe named m and the data burst interval transmission, NTT1. Then the transmission of a long-interval transition begins in the Downlink (DL) subframe number K of frame a, and a hybrid automatic redundant request is sent on the transmission of the long-interval transition in the uplink subframe number F of frame b. If the downlink hybrid automatic redundant reply is a negative ack (NACK) signal, the transmission of the data burst is retransmitted in the h or next subframe of frame C. The coefficients of frames a, b, and c and the coefficients of subframes h and f are determined according to the coefficients i, l, and m acquired from the data batch allocation information, and the index of a subframe uplink named n corresponds to coefficients i, l, and m, and NTT1 as follows.

If D-mNTT1, the transmission of the long-interval transition indicated by the data burst allocation information begins in subframe m of frame i hence i=a and m=h. On the other hand, if Dm<NTT1, the remaining downlink frame period is smaller than NTT1, so the transmission of the data burst cannot be transmitted in frame i. Hence the transmission of a long interval transmission starts at subframe zero of frame (1+i), a=1+i and h=zero.

To avoid concentrating downlink hybrid auto redundant replies in a specific uplink subframe, the parameter f of the uplink subframe carrying the downlink hybrid auto redundant on the data batch is determined according to the parameter l of the downlink subframe carrying the data batch assignment information. The relationship between l and f follows the relationship between m and n defined in Table (3). Accordingly, a downlink hybrid automatic redundant reply is sent in the next frame, so b=a+1(=i+2).

For example, if NTT1 = 5, NA-MAP = 1, and processing time Tx/Rx = 3 in a 5:3 TTD architecture, the transmission of a long interval transmission described by the data batch assignment information sent in a downlink subframe is no. 2 (=l 2) for frame i starts in the DownLink (DL) subframe number zero (h=zero) for frame (1+i) (a=(i+1)) because Dm(5-2)<NTTi( =5), and a downlink automatic hybrid redundant request reply is sent on the data burst in the uplink subframe number (n=l) of frame i+2)) b=(i+2)).

In another example, if the Transmission Time Interval (TTI) takes up an entire downlink period in downlink time division duplex, the transmission of a data burst always begins in downlink subframe number zero. In this system, when data allocation batch information is detected in downlink subframe number l downlink transmission long time interval transmission, and if l=0, the coefficients of subframes m and n and frame coefficient j for hybrid auto redundant operation are calculated by Table No. (3). In contrast, if l is zero, the data burst assignment information shows that the transmission of the data burst begins at subframe zero of the (1+i) next frame i. A hybrid automated redundant request reply is sent to the data burst in subframe n of frame j. In this application, n and j are calculated using equation (15) and not using table (3). That is, the location at which a hybrid automated redundant request response, n and j, is sent, is determined based on the index of a subframe l of the data batch allocation information and the frame parameter (1+j) of the data batch

. . . . . (14)

Where m=zero and D=TTT1. Therefore z is calculated by equation (15) by substituting zero and D for m and NTT1, respectively in equation (13). In this equation, n is determined based on the parameter l of the subframe carrying the data batch allocation information.

. . . . . (15)

Referring to Table (4) for a downlink hybrid automatic redundant, the data burst assignment information sent in the DownLink (DL) subframe (l) of frame (i) shows that the transmission of the data burst begins in the subframe. Uplink number m for frame j using NA-MAP and the index of a subframe for a DownLink (DL) named l. In the case of a long-interval transmission, the start of the transmission of the data burst is determined according to the index of a subframe uplink called m and the transmission of the data burst called NTT1. Thus, the transmission of a long-interval transmission begins in downlink subframe number h of frame a, and a hybrid automatic redundant request is transmitted for the transmission of a long-interval transmission in downlink subframe number f of frame b. If the downlink hybrid automated redundant reply is a negative ack (Nack) signal, transmission of the data burst occurs in uplink subframe number h of frame c. The frame parameters a, b, c and the sub-frame parameters h and f are determined according to the parameters i and l carrying the data batch allocation information, and the frame parameters are uplink and the uplink subframe named j and m corresponds to the parameters i and l, and NTT1 is as follows.

When i=j, and if U-mNTT1, the transmission of the long-interval transmission indicated by the data burst allocation information starts at subframe m of frame j, so i=a and m=h. On the other hand, if Um<NTT1 becomes j=i+1, the remaining uplink frame period is smaller than NTT1 so the transmission of the data burst cannot be transmitted in frame i. Hence, the transmission of a long interval transmission begins in uplink subframe number zero of frame (1+i), so i+1=a and h=zero. Since a hybrid automatic downlink redundant is sent in downlink subframe number l, f=1. Referring to Equation (14), if uh-NTT1+1Rx-Time4, a downlink hybrid automatic redundant is sent in frame b(b=(a+1)). If Uh-NTTI+l<Rx_Time4, a downlink hybrid auto redundant is sent in frame bth (b=(a+2)). If the downlink hybrid automated redundant reply is a Negative Ack (Nack) Signal, retransmission begins in uplink subframe number h of frame c. Likewise, as calculating the frame coefficient a, if i=a then c=b, and if i+1=a then c=b+1.

For example, if NTT1 = 3, NA-MAP = 1, and processing time =Tx/Rx 3 in architecture 5: 3 Time Division Duplex The transmission of the data burst uplink shown by the data burst assignment information in DownLink (DL) subframe 2 of frame i begins in uplink subframe zero (h = zero). For the (i+1)th frame (a=(i+1)) because Um (3-1)<NTTI(=3) and a downlink automatic hybrid redundant request reply is sent on the data burst in uplink subframe No. 2 (f =2) for the (i+2)th frame (b=(i+2)).

If the downlink hybrid automatic repeat request response is a NEGATIVE ACK (NACK) SIGNAL, retransmission occurs in the zero uplink subframe of frame (i+3), i.e. (b+1 = i+3), Likewise, the calculation of a=i+1 based on the deviation of a hybrid automated recurring request with time processing is 1.

In another example, if a Transmission Time Interval (TTI) transmission takes a long time to fully uplink in uplink time division duplex, the transmission of a data burst always begins in uplink subframe number zero. In this system, when the data burst assignment information in a DownLink (DL) subframe shows a long Transmission Time Interval (TTI) transmission of the data burst corresponding to the subframe parameter index of a subframe number l starts at subframe zero of the frame =m)j zero). A hybrid automatic redundant request reply is sent to the data burst in downlink subframe number l of subframe k.

If the hybrid redundant response is a NEGATIVE ACK SIGNAL, the hybrid redundant retransmission begins in uplink subframe zero of the P frame.

The frame coefficients j, k, and p are calculated using the equations defined in Table (4) using the deviation of the hybrid automated recurring request with time processing, called v, and the deviation of the hybrid automated recurring request called w, which are determined by taking m = zero.

In a Frequency Division Duplex (FDD) frame, the Downlink (DL) subframes and Uplink subframes are consecutively in their different frequency bands. This can initiate a long Transmission Time Interval (TTI) transmission in any subframe. However, if the start of a long-interval transmission transmission is limited to a specific subframe due to implementation complexity or other factor, control information (such as resource allocation information and Hybrid Automatic Repeat reQuest (HARQ) information) can be concentrated ) in a specific subframe, such as in a Time Division Duplex frame. Accordingly, the timing of a hybrid automatic redundant request in FDD, such as (Time Division Duplex), must be reset.

If the start of a long-slot transmission transmission is limited to a specific downlink subframe, downlink subframe number A long time slot transmission transmission includes at least one downlink subframe (x1, x2, .. ., xmax). In this case NA-MAP = 1. That is, when the assignment information of a data batch transmitted in downlink subframe number l (lx) indicates the transmission of a long-slot transition, the transmission of a long-slot transition begins in a downlink subframe after subframe number l.

In the previous case, if the allocation information of the data batch sent in the downlink subframe shows the number l transmitted. For downlink long interval transmission and x=l, the coefficients of subframes m and n and the frame coefficient j of hybrid automatic redundant operation are calculated by Table (1). Otherwise, if xl, the transmission of the data burst begins in frame m. A hybrid automated redundant request reply is sent to the data burst in subframe n of frame j. In this case, the parameters m, n, and j are determined by equation (17) and not by table (1). That is, the location of a hybrid automated redundant request, (n, j) is determined based on the DownLink (DL) subframe parameter called l for the data batch allocation information, the index of a subframe x, and the frame parameter Batch data indexes.

. . . . . (16)

where denotes the ith subframe of frame i and .

For example, if the beginning of an interval transition transmission coincides with DownLink (DL) subframes 0 and 4, then F = 8, NTT1 = 4, and processing time Tx/Rx = 3 subframes, then the transmission of an interval transition ( The long TTI described by the data burst assignment information in the first, second, and third downlink subframes (i.e., Long time interval (TTI) in the subframe Uplink number n of frame (1+i). In this case, n ranges between 5 and 7. In this case (ceil(8/2)-4+3) is 3 and so Z=0. Likewise, the transmission of the long-interval transmission described in the data burst assignment information in the fifth to seventh DownLink (DL) subframes of subframe i begins in downlink subframe zero of frame (1+i) (m=zero), and is transmitted Hybrid automatic redundant request response to a long interval transmission transmission in uplink subframe number n of frame (i+2). In this case, n ranges between 1 and 3. In this case, (ceil(8/2)-4-5) < 3, so z = 1.

In a hybrid uplink automatic redundant with frequency division duplex, if the beginning of the transmission of a long time interval transmission is restricted to a specific uplink subframe. The index of an uplink subframe is y For a downlink HARQ operation in a Frequency Division Duplex (FDD) system, the following Hybrid Automatic Repeat reQuest (HARQ) timing may be taken into Consideration. The transmission of a long time slot transmission includes at least one uplink subframe (y1, y2, . . .). , ymax).

In the previous case, if the allocation information of the data batch transmitted in the downlink subframe number l shows that an uplink is being transmitted for a long time slot transmission and that y=n , the index of a subframe m and the index of frame j are calculated for a hybrid auto-repeat operation According to Table (2). Otherwise, if yn, the transmission of the data burst begins in uplink subframe number m. That is, the data burst assignment information shows that a transmission of the data burst was sent in the downlink subframe number l of frame k. If the hybrid redundant reply is a negative ack signal (NACK) signal or buffer and a source assignment for retransmission is indicated, then the hybrid redundant retransmission begins in the m subframe of the P frame. In this case, the parameters m are determined And j, K, and p are determined by equation (18) and not by table (2). That is, the location of a hybrid automated redundant request, (m,j), is determined based on the downlink subframe parameter index of a subframe named l of the data batch allocation information, the index of a subframe y and the index of frame i of the data batch.

The frame coefficients j, k, and p are calculated by the equations defined in Table (2) using the deflections (HARQ) Tx and Hybrid Automated Recurring Request (HARQ) called v and w, which are determined by taking m = zero.

For example, if the start of a Transmission Time Interval (TTI) transmission matches uplink subframes 0 through 4 (i.e., y1 = 0, y1 = 4), F = 8, NTT1 = 4, and processing time time Tx/Rx = 3 subframes, the transmission of a long-interval transmission that shows data batch allocation information in the first, second, and third downlink subframes (i.e., where and ) of frame i begins in uplink subframe number zero of frame (i+1). ) and that an automatic hybrid recurring request response is sent to Send Long time interval transmission in the first, second and third downlink subframes of the (i+2)th frame. In this case (ceil(8/2)-1+0-n) < 3 so V = 1. Since (floor(8/2)-4+n-0) 3, W = zero. Likewise, the transmission of a long interval transmission whose data batch allocation information is indicated in the fifth, sixth, and seventh downlink subframes (i.e., where , ) of frame i begins in the fourth uplink subframe of frame (i+1) (m=4), and a response is sent. Automated hybrid redundant request to transmit a long interval transmission in the l subframe (l one of 5, 6, and 7) of frame (i+2). If the hybrid redundant reply is a negative ack (NACK) signal, and a source assignment is indicated for retransmission, then the hybrid redundant retransmission begins in the fourth uplink subframe of frame (i+3). Since (ceil(8/2)-1+4-n) 3 then v = zero. Since (floor(8/2)-4+n-4) < 3, w= 1.

In another representative embodiment of the present invention, if data batch allocation information is transmitted in each downlink subframe, NA-MAP = 1. Then tables (1-4) are modified to tables (5-8) respectively. The following tables may be used to determine the transmission time Allocating at least one of the advanced informatics elements using the data batch allocation information, a subpacket state of the data batch, and a Hybrid Automatic Repeat reQuest (HARQ) (ACK or negative receive signal) NEGATIVE ACK (NACK) SIGNAL, and a subpacket for retransmitting a hybrid automatic recursive request. However, it is understood that the tables should not be considered a limitation of the present invention.

For example, when each superframe includes four frames as shown in Figure (1), then N = 4 in Tables (5-8). If DU is in a hybrid auto redundant callback in an uplink table (7) or a Tx subpacket in an uplink hybrid auto redundant subpacket in table (8), then N will be equal to it regardless of the previous equations. That is, n=mk. According to a modified embodiment, a sender and a receiver possess at least one table with result values corresponding to all possible input values according to Table Equations (4-8) or (9-12) and can read all results corresponding to the current input values to determine the timing of a hybrid automated recurring request. In one example the input values represent the index of a subframe and the frame indexes for an A-MAP IE Tx assignment in a DownLink (DL).

As a further representative embodiment of the present invention it may be envisaged that the timings of the aforementioned downlink hybrid automatic redundant operation can be applied to channels in which a source assignment has been placed in a particular relationship with an uplink transmission. For example, in the case of an uplink fast reply channel, the Base Station (BS) sends source assignment information for an uplink fast reply in subframe l of frame i. The timing of transmission of fast uplink reply information, i.e. frame and subframe parameters, is determined by i and l. More specifically, the frame parameter j and the index of a subframe m of fast uplink reply information are determined by one of the tables (2, 4, 6 and 8).

Whereas herein it has been described with respect to a Time Division Duplex frame system that DownLink (DL) subframes and u subframes have their transactions entered separately within a downlink and an uplink, the downlink subframes and u subframes are An uplink whose transactions can be entered sequentially within a frame that includes a downlink and an uplink. Then the parameter

Figures 18 and 19 are diagrams illustrating process signal flows between a Base Station (BS) and a Mobile Station (MS) according to downlink hybrid auto redundant timing architectures and downlink hybrid auto redundant timing architectures according to representative embodiments of the present invention.

Referring to Figure 18, the Base Station (BS) sends the system configuration information to the Mobile Station (MS) in step 1802. The system configuration information is broadcast by the base station or acquired by navigation between the BS and the BS. Portable Allows the portable station to access the system. System configuration information is required to implement hybrid auto redundant timing structures, including bandwidth (total number of subframes), number of subframes per link (downlink and uplink), processing time for a base station's Tx/Rx, and Tx processing time /Rx for portable station.

After the Mobile Station (MS) acquires system information from the system configuration information and communicates with the Base Station (BS), the BS and MS are able to perform a data communication between each other in step 1804. In a modified embodiment, the Step 1804 When a portable station already knows the system configuration information.

In step 1806, the Base Station (BS) transmits assignment information including or describing a frame indexes, index of a subframe, long time interval transmission, and relevant MAP information to the Mobile Station (MS). In a DownLink (DL) subframe, the number l of frame i. A portable terminal extracts the information necessary to decode the personalization information. A portable terminal specifically determines the frame and subframe parameters of each HARQ process based on the frame and subframe parameters of the preceding Hybrid Automatic Repeat reQuest (HARQ) process according to at least one representative embodiment of the present invention.

In step 1808, the Base Station (BS) transmits a downlink auto-repeat burst code in the h subframe of frame a according to the assignment information and the Mobile Station (MS) decodes a downlink auto-repeat burst code based on the assignment information. A portable station transmits a hybrid auto-redial reply to a downlink hybrid auto-redial batch according to the decoding result to a base station in subframe f of frame b in step 1810.

In step 1812, the following assignment information can be transmitted in subframe h of frame c according to the specified assignment information transmission period. If the hybrid autorepeat reply is a Negative Ack (NACK) Signal, the downlink hybrid autorepeat batch can be retransmitted in step 1814.

Referring to Figure 19, the Base Station (BS) sends system configuration information to the Mobile Station (MS) in step 1902. After the mobile station acquires the system information from the system assignment information and reaches the Base Station ( BS), the base station and the mobile station are capable of performing a data communication with each other in step 1904.

In step 1906 a base station transmits assignment information including or describing a frame indexes, a subframe parameter, a long interval transmission, and relevant MAP information to a mobile station (MS) in downlink subframe number l of frame i. A portable terminal extracts the information necessary to decode the personalization information. A portable terminal specifically determines the frame and subframe parameters of each hybrid automated repeating process based on the subframe parameters of the preceding hybrid automated repeating process in accordance with at least one representative embodiment of the present invention.

In step 1908, a mobile station transmits a downlink hybrid auto-repeat burst code in the h subframe of frame a according to the assignment information and the Base Station (BS) decodes the downlink hybrid auto-repeat burst code based on the assignment information. A base station transmits a hybrid auto-repeat reply on a downlink hybrid auto-repeat batch according to the decoding result, or the following assignment information, to a Mobile Station (MS) in subframe f of frame b in step 1910. If the hybrid auto redial reply is a negative ack (Nack) signal, an uplink hybrid auto redundant batch can be retransmitted in subframe h of frame 2 according to a transmission period specified in step 1912.

In order to implement at least one of the prior representative embodiments of the present invention, each Base Station (BS) and Mobile Station (MS) includes a control unit having a processor, a memory for storing program codes and related parameters necessary for operations and the control unit, and a transmitter and a receiver for exchanging signaling messages or data traffic with the other party under the control of the controller. The controller controls the timings of a hybrid automated repeating request to perform sender and receiver operations in accordance with at least one of said representative embodiments of the present invention.

As can be seen from the foregoing description, representative embodiments of the present invention enable flexible hybrid automatic redundant transmissions according to different frame modulation for different system bandwidth, downlink:uplink ratio, and system support scheme (inherited from the prior art). Because timings for a hybrid automatic recurring request with time processing are determined flexibly in a wireless mobile communication system.

The prior synchronous relationship reduces the number of subframes that a receiver must monitor, thus saving energy. A Mobile Station (MS) can also communicate with another system more freely using specific process timings.

While the present invention is illustrated and described by reference to certain representative examples, it is understood by those skilled in the art that various changes may be made therein without departing from the substance and scope of the invention as set forth in the attached claims and equivalents.
