QUALITY OF SERVICE BASED RESOURCE DETERMINATION AND ALLOCATION APPARATUS AND PROCEDURE IN HIGH SPEED PACKET ACCESS EVOLUTION AND LONG TERM EVOLUTION SYSTEMS

FIELD OF THE INVENTION The present invention relates to medium access control (MAC) designs for high speed packet access evolution (HSPA+) and long term evolution (LTE) systems. More specifically, the present invention relates to a method and apparatus for allocating physical resources and transport format attributes to a plurality of parallel data streams according to quality of service (QoS) requirements of data transmitted in a common transmission period (TTI).

Wireless communication systems are well known in the art. Communication standards have been developed to provide global connectivity for wireless systems and to achieve performance targets, for example in terms of throughput, latency and coverage. One standard, called Universal Mobile Telecommunications System (UMTS), which is widely used today, was developed as part of Third Generation (3G) wireless systems and is maintained by the Third Generation Partnership Project (3GPP).

1 shows a typical UMTS system structure according to the current 3GPP standard. The UMTS network structure includes a core network (CN) interconnected with a UMTS Terrestrial Radio Access Network (UTRAN) via an Iu interface. The UTRAN is configured to provide wireless telecommunication services to users via a wireless transmit/receive unit (WTRU) referred to as a user equipment (UE) within the 3GPP standard over a Uu air interface. A commonly used air interface specified in the UMTS standard is Wideband Code Division Multiple Access (W-CDMA). The UTRAN has one or more radio network controllers (RNCs) and base stations referred to as Node Bs by 3GPP, which jointly provide geographic coverage for radio communications with the UE. One or more Node Bs are connected to each RNC via an Iub interface; RNCs in UTRAN communicate via the Iur interface.

The Uu air interface of the 3GPP system uses a transport channel (TrCH) for the transmission and signaling of user data between the UE and the Node B. In 3GPP communication, TrCH data is carried by one or more physical channels defined by a mutually exclusive physical resource or, in the case of a shared channel, defined by a shared physical resource. TrCH data is transmitted in sequential groups of transport blocks (TB) defined as transport block sets (TBS). Each TBS is transmitted in a given transmission period (TTI), which may span a plurality of consecutive system time frames. For example, according to the 3GPP UMTS Release '99 (R99) specification, a typical system time frame is 10 microseconds, and the TTI is specified as spanning 1, 2, 4 or 8 such time frames. In enhancements to the UMTS standard part of the Release 5 specification according to High-Speed Downlink Packet Access (HSDPA), and in the enhancements to the Release 6 specification part according to High-Speed Uplink Packet Access (HSUPA), the TTI is generally 2 ms, so This is only part of the system time frame.

With respect to time division duplex (TDD) communication in 3GPP TS 25.222, for example, processing a TrCH into a Code Composite TrCH (CCTrCH) followed by one or more physical channel data streams is described. Starting with the TBS data, a cyclic redundancy check (CDC) bit is appended, and transport block combining and code block segmentation are performed. Convolutional coding or turbo coding is then performed, but in some examples no coding is specified. The steps after coding include radio frame equalization, first interleaving, radio frame fractionation and rate matching. Radio frame fractionation divides data beyond the number of frames in a designated TTI. The rate matching function operates by bit repetition or puncturing and defines the number of bits for each processed TrCH that are subsequently multiplexed to form a CCTrCH data stream.

In a typical 3GPP system, a Node B can communicate with other UEs simultaneously using each different CCTrCH data stream, but communication between the UE and the Node B is performed using a single CCTrCH data stream.

Processing of the CCTrCH data stream includes bit scrambling, physical channel segmentation, second interleaving, and mapping onto one or more physical channels. The number of physical channels corresponds to a physical channel fraction. For uplink transmission from UE to Node B, the maximum number of physical channels for CCTrCH transmission is currently specified as two. For downlink transmission from Node B to UE, the maximum number of physical channels for CCTrCH transmission is currently specified as sixteen. Each physical channel data stream is then spread with a channelization code and modulated for wireless transmission using the assigned frequency.

In the reception/decoding of TrCH data, the processing is essentially reversed by the receiving station. Therefore, the physical reception of the UE and the Node B of the TrCH requires information of the TrCH processing parameters in order to reconstruct the TBS data. For each TrCH, a transport format set (TFS) is designated to include a predetermined number of transport formats (TF). Each TF specifies various dynamic parameters including TB and TBS size, and various quasi-static parameters including TTI, coding type, coding rate, rate matching parameters and CRC length. A predefined set of TFS for TrCH of CCTrCH for a specific frame is denoted as a Transport Format Combination (TFC). One TFC is selected per TTI for each UE so that one TFC is processed per TTI per UE.

Receive station processing is facilitated by transmission of a Transport Format Combination Indicator (TFCI) for the CCTrCH. For each TrCH of a particular CCTrCH, the transmitting station determines a particular TF of the TFS of the TrCH that will be valid during the TTI, and identifies that TF by a Transport Format Indicator (TFI). TFIs of all TrCHs of CCTrCH are combined to form TFCI. For example, if two TrCHs, TrCH1 and TrCH2, are multiplexed to form CCTrCH1, then TrCH1 has two possible TFs in its TFS, namely TF10 and TF11, and TrCH2 has four possible TFs in its TFS. With TFs, namely TF20, TF21, TF22 and TF23, valid TFCIs for CCTrCHl may include (0,0), (0,1), (1,2) and (1,3), but not necessarily It is not possible to include all possible combinations. Reception of (0,0) as TFCI for CCTrCH1 informs the receiving station that TrCH1 has been formatted as TF10 and TrCH2 has been formatted with TF20 for the TTI of the received CCTrCH1, and that of (1,2) as TFCI for CCTrCH1 The reception notifies the receiving station that TrCH1 is formatted as TF11 and TrCH2 is formatted as TF22 for the TTI of the received CCTrCH1.

In UMTS Specification Releases 5 and 6, which belong to HSDPA and HSUPA, respectively, high-speed retransmission is achieved according to hybrid automatic repeat request (HARQ). Currently, it is specified that only one Hybrid Automatic Repeat Request (HARQ) process be used per TTI.

High-Speed Packet Access Evolution (HSPA+) and Universal Terrestrial Radio Access (UTRA) and UTRAN Long-Term Evolution (LTE) are the current It's part of the effort. In this regard, both HSPA+ and LTE are being designed with significant changes to the conventional 3GPP air interface and radio network architecture. For example, in LTE, Code Division Multiple Access (CDMA) channel access currently used in UMTS is compared to Orthogonal Frequency Division Multiple Access (OFDMA) and Frequency Division Multiple Access (OFDMA) as air interface technologies for downlink and uplink transmission, respectively. FDMA) has been proposed. The air interface technology proposed by HSPA+ is based on code division multiple access (CDMA) but has a more efficient physical (PHY) layer structure that can contain independent channelization codes that are distinct with respect to channel quality. Both HSPA+ and LTE are designed to support multiple input multiple output (MIMO) communications physical layer. In this new system, multiple input streams can be used for communication between the UE and the Node B.

The inventor of the present invention has recognized that conventional 3GPP medium access control (MAC) layer procedures are not designed to address the new PHY layer structures and features of the proposed system. TFC selection in the current UMTS standard includes, by way of non-limiting example, time and frequency distribution in LTE and number of subcarriers, channelization code in HSPA+, and different antenna beams in the case of MIMO, HSPA+ and LTE It does not take into account some of the new transport format (TF) attributes introduced by .

According to the MAC procedure specified in the current UMTS standard, only one Transport Format Combination (TFC) selection process is required to determine the necessary attributes for transmission over a physical channel starting at a common transmission period (TTI) boundary. , data multiplexed into transport blocks are mapped to one data stream at a time. Thus, only one Hybrid Automatic Repeat Request (HARQ) process controlling data retransmission for error correction is allocated for communication between any given UE and Node B. According to the PHY layer changes proposed with respect to HSPA+ and UMTS described above, for a given UE and Node B communication, multiple physical resource groups can be made available simultaneously for data transmission, resulting in potentially multiple data Streams are transmitted for communication.

The inventors of the present invention propose that multiple input streams start at a common TTI boundary, each with common or different quality of service (QoS) requirements requiring specific transmission properties such as modulation and coding, and different hybrid automatic repeat request (HARQ) processes. I knew I could have it. As an example, in the case of multiple input multiple output (MIMO) communication, independent data streams may be transmitted simultaneously because of spatial diversity; Each spatially diverse data stream requires its own transmission properties and HARQ process to satisfy its own desired QoS requirements due to different channel characteristics. Currently, there is no MAC method and procedure that simultaneously assigns attributes to multiple data streams and efficiently provides the same or unequal QoS to parallel data streams.

The inventors of the present invention have developed a method for selecting multiple transport formats in parallel according to channel quality metrics and QoS requirements using new PHY layer properties and features of HSPA+ and LTE systems.

The present invention provides a medium for addressing changes proposed by high-speed packet access evolution (HSPA+) and long-term evolution (LTE) systems, including physical layer structure and properties, dynamic resource allocation, transmission schemes such as MIMO, and multiple QoS requirements. A method and apparatus are provided for transport format combination (TPC) selection at an access control (MAC) layer. A method of driving a multiple TFC selection procedure is provided to simultaneously assign transmission attributes to parallel data streams that satisfy quality of service (QoS) requirements of data according to physical channel characteristics. The present invention supports the transmission of multiple data streams over a common transmission period (TTI) boundary with standardized QoS or differentiated QoS via parallel TFC selection functions. Significant changes are introduced to the existing 3GPP TFC selection procedure defined in the High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) protocols that address the new features in the HSPA+ and LTE systems described above. The present invention readily provides for dynamic HARQ process assignment where different hybrid automatic repeat requests (HARQs) are applicable to the data stream.

In a preferred embodiment, a wireless transmit/receive unit (WTRU) comprises a receiver and a transmitter, and a method is provided for processing communication data in processing layers including a physical (PHY) layer, a medium access control (MAC) layer and higher layers. do. The MAC layer transmission format selection device defines the allocation of upper layer transmission data to the parallel data stream based on the data characteristics received from the upper layer and the physical resource information received from the PHY layer. The transport format selection device also generates a transport format parameter for each data stream. The multiplexer component multiplexes the transmission data into a parallel data stream in units of transport blocks according to each transport format parameter generated by the data stream assignment and transport format selection device, and selectively converts the multiplexed transmission data into one or more for wireless signal transmission. output to the PHY layer for transmission through each physical resource partition via the antennas. Preferably, the transport format selection device also generates physical transmission properties such as modulation and coding rate (MCR), number of subframes per transmission period (TTI), TTI length, transmission power and hybrid automatic repeat request (HARQ) parameters. .

The present invention may be used in both uplink (UL) and downlink (DL) communications, and thus may be used in a wireless transmit/receive unit (WTRU), also referred to as a user equipment (UE), or a Node B, also referred to as a base station.

In general, a wireless transmit/receive unit (WTRU) is a user equipment, mobile station, fixed or mobile subscriber unit, pager, cellular phone, personal assistant (PDA), computer, or other type of other capable of operating in a wireless environment. device, but are not limited to these examples. A base station is any type of WTRU that is generally designed to provide network services to multiple WTRUs, including a Node B, a site controller, an access point, or any type of interfacing device in a wireless environment, but these examples include is not limited to

Channelization code for HSPA+, number and distribution of subcarriers in frequency and time domain for LTE, different antenna beams in multiple input multiple output (MIMO) scheme for HSPA+ and LTE, MIMO scheme for HSPA+ and LTE A modified MAC protocol is provided to account for the new properties and resources introduced by the high-speed packet access evolution (HSPA+) system and the long-term evolution (LTE) system, including but not limited to a subset of the antennas of For HSPA+ systems and LTE systems using MIMO, the present invention provides different link adaptation parameters, eg different modulation and coding schemes, for each of a plurality of parallel data streams. Preferably, a plurality of parallel data streams are assigned to different physical resource groups in different spatial channels based on the channel quality of the channel and the quality of service (QoS) requirements of the data being transmitted. Specifically, a method is provided for standardizing QoS across parallel data streams if the same QoS is desired, and different QoS requirements for parallel data streams if the data streams are derived, for example, from different radio bearers with different QoS requirements. A method for realizing a condition is provided.

A preferred embodiment of selected components included in the receiver is shown. TFC selection is a process that occurs for each active data stream prior to each transmission period (TTI) and involves determining how to transmit the data.

The medium access (MAC) layer processing arrangement 200 provides one or more radio bearers 204 via the Radio Link Control Protocol (RLC) layer for a given communication link between the UE and the Node B provided by the upper layers.<sb>1</sb> to 204<sb>M</sb>) to receive data from The higher layers, including, by way of non-limiting examples, the RLC layer, the radio resource control (RRC) layer and the layer 3 are represented by the higher layer configuration 203 that resides above the MAC layer processing configuration 200 . radio bearer (204<sb>1</sb> to 204<sb>M</sb>. It is buffered in a buffer 219 in the layer.

The MAC layer processing component 200 also provides quality of service (QoS) requirements and other data characteristics 202 for each radio bearer.<sb>1</sb> to 202<sb>M</sb>) is configured to receive QoS requirements provided by higher layers (i.e., layer 3 or higher) include number of hybrid automatic repeat request (H-ARQ) retransmissions, block error rate, priority, allowed data combinations and/or power offset can, but is not limited thereto. Other data characteristics may include items such as buffer characteristics for each data channel of the radio bearer.

From the physical (PHY) layer represented by the physical layer configuration unit 201, the MAC layer processing component 200 is configured for each available physical resource group, such as channel quality metrics and dynamic scheduling parameters that are subject to fluctuating for each TTI. Channel Characteristics for (206)<sb>1</sb> to 206<sb>N</sb>) is received. A transport format combination (TFC) selection device 208 is provided as part of the MAC layer processing component 200 . The TFC selection device 208 transmits information 202 from upper layers.<sb>1</sb> to 202<sb>M </sb>and 207) and information 206 carried from the PHY layer.<sb>1</sb> to 206<sb>N</sb>) based on the radio bearer data 204<sb>1</sb> to 204<sb>M</sb>) and available physical resource partitions.

The channel characteristics of the available physical resources signaled from the PHY layer to the MAC layer for each TTI for the purpose of TFC selection may take the form of, for example, a Channel Quality Indicator (CQI) for Channel Quality. A subchannel may be provided as a subcarrier in LTE and as a channelization code in HSPA+. The present invention considers new dynamic transport format (TF) parameters that are easy to change for each TTI as introduced by LTE and HSPA+, and these TF parameters include an allowable transport block (TB) or TB set size, the number of subframes, Modulation rate, coding rate, time and frequency distribution of subcarriers (for LTE), number of subchannels (ie subcarriers or channelization codes), maximum allowable transmit power, antenna beam in MIMO, antenna sub in MIMO set, TTI length and H-ARQ parameters are included, but are not limited thereto. These dynamic TF parameters are preferably based on the PHY layer data 206<sb>1</sb> to 206<sb>N</sb>A decision is made in the TFC selection unit 208 prior to each TTI based on the corresponding constraint provided by .

Some TF parameters are considered semi-static because they take one or more TTIs to change, and thus are updated after multiple TTIs rather than dynamically for each TTI. Examples of quasi-static TF parameters are the type of channel coding and the size of the cyclic redundancy check (CRC). Preferably, the quasi-static parameter is determined by signaling the information 207 to the transport format combination (TFC) selection device 208 from a higher layer, eg a radio resource control (RRC) layer.

TFC selection device 208 transmits radio bearer data 204<sb>1</sb> to 204<sb>M</sb>) and parallel TFC selection functions 210 corresponding to available physical resource partitions<sb>1</sb> to 210<sb>N</sb>), which is configured to assign to these parallel TFC selection functions 210<sb>1</sb> to 210<sb>N</sb>) is the radio bearer data 204<sb>1</sb> to 204<sb>M</sb>) to each data stream 209<sb>1</sb> to 209<sb>N</sb>), and each HARQ process 230 for the PHY layer.<sb>1</sb> to 230<sb>N</sb>), and then the PHY layer for each HARQ process 240<sb>1</sb> to 240<sb>N</sb>) is applied to each data stream. data stream (209<sb>1</sb> to 209<sb>N</sb>) may consist of data from one or more logical channels, and each data stream may be obtained from a single radio bearer or multiple radio bearers. The data of a single radio bearer may be split and assigned to different data streams as determined by the TFC selection unit 208 . For example, if only one radio bearer carries data, in order to efficiently use all available physical resource partitions, especially in UL transmission, the data of this radio bearer is preferably divided into streams.

In general, the available physical resource partitions are the PHY layer 206<sb>1</sb> to 206<sb>N</sb>) will be specified in the information received from For uplink (UL) transmission, the TFC selection device may receive an explicit partition command from RRC layer signaling 207 indicating a physical resource partition and transmission parameters for each physical resource in each partition. Similarly, the signaling 207 from the RRC layer may indicate regarding a partition that is data flow or radio bearer specific. To the extent allowed, PHY layer information 206<sb>1</sb> to 206<sb>N</sb>) may include an alternative selection in grouping physical resources for a physical partition. In this case, the TFC selection device 208 also includes the PHY layer 206<sb>1</sb> to 206<sb>N</sb>) and/or the allowable partitioning criteria signaled from the RRC layer 207 .

The TFC selection device 208 is preferably a data stream 209<sb>1</sb> to 209<sb>N</sb>) in defining the radio bearer 204<sb>1</sb> to 204<sb>M</sb>) match the data QoS requirements of the channel data of the physical channel quality with respect to the available physical resource partitions. TFC selector 208 passes through assignment data 214 to data stream 209<sb>1</sb> to 209<sb>N</sb>) for the radio bearer (204)<sb>1</sb> to 204<sb>M</sb>) to the multiplexer component 220 , thereby providing a radio bearer 204<sb>1</sb> to 204<sb>M</sb>) of the channel data of each assigned data stream 209<sb>1</sb> to 209<sb>N</sb>) is sent appropriately. data stream (209<sb>1</sb> to 209<sb>N</sb>) represents the selected segmentation of the radio bearer's data for communication between the UE and the Node B, which is somewhat similar to the prior art single CCTrCH or single TrCH data stream, respectively, but followed by independent processing/transmission tracks.

TFC selection function (210<sb>1</sb> to 210<sb>N</sb>) is the parallel data stream 209<sb>1</sb> to 209<sb>N</sb>), generate a transmission format (TF) or TF set based on the channel quality parameter of the corresponding physical resource partition to provide the desired QoS for . TF selection for each selected physical resource partition is signal 230<sb>1</sb> to 230<sb>N</sb>) is provided in the PHY layer as indicated by TFC selection function (210<sb>1</sb> to 210<sb>N</sb>) is also preferably the number of subframes, modulation rate, coding rate, time and frequency distribution of subcarriers (for LTE), number of subchannels (ie subcarriers or channelization codes), maximum allowable transmit power, Allows selection of available parameters for the physical resource of the physical resource partition, such as antenna beam in MIMO, antenna subset in MIMO, TTI length and H-ARQ parameters. These choices are in most cases limited by the PHY layer. However, the TFC selection function (210<sb>1</sb> to 210<sb>N</sb>) this data stream (209<sb>1</sb> to 209<sb>N</sb>) signal HARQ process for 230<sb>1</sb> to 230<sb>N</sb>), the total amount of HARQ resources available to allocate to the PHY layer may be signaled to the MAC configuration unit 200 . The HARQ partition assignment is affected by the values of other related parameters, in particular the values of modulation and coding scheme (MCS) and TB size. Each data stream 209<sb>1</sb> to 209<sb>N</sb>) when determining the HARQ partition assignment for the TFC selection function 210<sb>1</sb> to 210<sb>N</sb>) considers the value of the physical layer parameter of each physical resource partition, preferably the value of MCS and TB size. In the more limited case, where the PHY layer dictates HARQ resource partitioning, the MAC component 200 is the data stream 209<sb>1</sb> to 209<sb>N</sb>) does not select the HARQ process assigned to it.

Each data stream (209<sb>1</sb> to 209<sb>N</sb>), TF selection including TB size for 215<sb>1</sb> to 215<sb>N</sb>is provided to the data multiplexer configuration unit 220 through The data multiplexer component 220 is configured for each upper layer data stream 209<sb>1</sb> to 209<sb>N</sb>) in association with the designated transport block (TB) or TB set 250 for each allocated physical resource partition determined by the TFC selection device 208.<sb>1</sb> to 250<sb>N</sb>) to use this information for fractionation. Preferably, TB (250<sb>1</sb> to 250<sb>N</sb>) is provided to the PHY layer for transmission over a physical channel resigning on a common transmission period (TTI) boundary. Preferably, the PHY layer includes one or more antennas for TB transmission over wireless signals.

Preferably, signal 230<sb>1</sb> to 230<sb>N</sb>) and TB(250<sb>1</sb> to 250<sb>N</sb>) may be coordinated in the MAC layer processing component 200 , combined and signaled together to the PHY layer processor prior to each TTI boundary.

In one embodiment, the TFC selection function 210<sb>1</sb> to 210<sb>N</sb>) is two or more data streams (209<sb>1</sb> to 209<sb>N</sb>) to create a transport format (TF) to standardize the expected QoS provided for This embodiment is preferred when data is derived from a radio bearer or radio bearer set with common QoS requirements transmitted in a common TTI.

In another embodiment, the TFC selection function 210<sb>1</sb> to 210<sb>N</sb>) is two or more data streams (209<sb>1</sb> to 209<sb>N</sb>) to create a transport format (TF) for differentiating the expected QoS provided to . This alternative embodiment provides data with different QoS for each data stream, when two or more radio bearer sets providing data have different QoS requirements, or when a single radio bearer, e.g., a voice stream, provides data with different QoS including priority. It is preferable to include

As shown in Figure 3, the exemplary basic processing steps 300 taken prior to each TTI boundary in relation to the MAC layer in accordance with the present invention include: buffer analysis 305, physical resource partitioning and data flow. Allocation (310), transmission attribute determination (315) and data multiplexing (320) are included. As already mentioned, the present invention provides that different HARQ data streams 209<sb>1</sb> to 209<sb>N</sb>), it easily provides HARQ process assignment by the MAC component when applicable.

In step 305, data meeting the quality of service (QoS) requirements and potential other characteristics including the physical resource partition requirements for the data are transferred to higher layers, such as a radio resource control (RRC) layer and a radio link control (RLC) layer. received from the floor. Parameters such as channel quality indicator (CQI) and dynamic scheduling information are preferably received from the physical (PHY) layer prior to the transmission period (TTI) during which the data is transmitted. In order to determine the QoS requirements of the available higher-layer data and available physical resource partitions with the relevant CQI level and dynamic scheduling information, the higher-level data information is analyzed through comparison with the PHY layer partition information. In step 310, there is an allocation of parallel data streams obtained from available physical resource partitions and upper layer channel data, for example by matching QoS requirements to CQI and dynamic scheduling information. In step 315, a transmission format (TF) or set of TFs associated with each data stream and the assigned physical resource partition is generated to wish for parallel data streams based on the dynamic scheduling information and channel quality parameters of the corresponding physical resource partition. to provide QoS. In connection with this step, parameters for physical resources allowed by the PHY layer are determined. For example, allocation of HARQ resources is preferably made. In step 320, a transport block (TB) according to the associated TF for each data stream provided to the PHY layer for communication over a physical channel, preferably starting at a common transmission period (TTI) boundary, and activated at the current TTI boundary. ) or TB sets, the upper layer data is multiplexed (eg, concatenated and partitioned) according to the data stream assignment. A detailed description of each step is provided below.

In general, QoS requirements are provided by higher layers so that the TFC selection function can determine the allowed data combinations for the data multiplexing step during the current TTI(s). Multiple logical channels or upper layer data flow<sb>1</sb> to 204<sb>M</sb>), QoS requirements include buffer occupancy information for each logical channel, an indication of the priority or highest priority data flow for each logical channel or data flow, packet size for each data flow, and allowed data.

The amount of data available for each allowed multiplexing combination, the number of corresponding HARQ retransmissions, the power offset, and/or other QoS related parameters associated with each data multiplexing combination are also preferably determined.

<b>Partitioning physical resources and allocating data flows</b>

Channel quality metrics and dynamic scheduling information (206)<sb>1</sb> to 206<sb>N</sb>The available physical resources provided by the physical layer along with It is partitioned into subchannel partitions based on the QoS and partitioning requirements of data and channel parameters. Determine the available subchannel partitions such that an available subchannel partition can be assigned to the data stream for each transmission of a multiplexed data combination belonging to the data stream.

According to a preferred embodiment, a CQI notification is generated for each available subchannel (subcarrier in time and frequency domain or channelization code in code domain) measured based on the pilot channel in the physical layer. In downlink (DL) communication, not all available subchannels are necessarily used for data transmission per each TTI. A threshold representing a desired limit of acceptable transmission performance is defined, such that only subchannels with corresponding CQI values above this threshold are used for transmission. Accordingly, the TFC selection function 210 ensures that only subchannels that meet the requirements are included in the assigned partition.<sb>1</sb> to 210<sb>N</sb>) is selected by This is preferably achieved by CQI based scheduling at Node B.

For UL communications, the Node B scheduler is, by way of non-limiting example, for each of the available subchannels, antenna beams, maximum allowed uplink (UL) power, and modulation and coding scheme (MCS) limits and/or allocated subchannels. information about the allocated physical (PHY) resources including the channel quality indicator (CQI) of the user equipment (UE). Advantageously, said information is provided for each physical channel available in connection with UL transmission. The PHY resource allocation may be changed or left unchanged during subsequent scheduling grants. This can be determined by identifying relative differences in subsequent scheduling grants. Sufficient physical resources may not be provided to the UE to selectively choose a subset set of available subchannels based on a threshold. In this case, the TFC selection device 208 may preferably use all available subchannels regardless of the CQI. A UL channel providing a CQI greater than a threshold may be identified in the scheduling grant. However, if the scheduling grant is valid across multiple TTIs, the CQI of each granted subchannel may change over time. TFC selection function (210<sb>1</sb> to 210<sb>N</sb>) is preferably a modulation and coding set (MCS), TB size, transmit power and/or HARQ retransmission for each subchannel or set of subchannels assigned to a particular physical resource partition in the transmit attribute determination step described below. Adjust accordingly. TFC selection function (210<sb>1</sb> to 210<sb>N</sb>) is preferably a data flow 209 mapped to a physical resource partition<sb>1</sb> to 209<sb>N</sb>) separates the data flow between subchannels or sets of subchannels assigned to specific physical resource partitions providing a CQI level that better meets the QoS requirements of

upper layer data (204<sb>1</sb> to 204<sb>M</sb>), the parallel data stream obtained from the TFC selection function 210 with respect to each available physical resource partition<sb>1</sb> to 210<sb>N</sb>) is assigned to Data stream allocation is preferably higher layer data 204<sb>1</sb> to 204<sb>M</sb>) are created according to the common QoS attributes of the various channels between TFC selection function (210<sb>1</sb> to 210<sb>N</sb>) preferably allocates data streams to available physical resource partitions by matching CQI levels and dynamic scheduling information to QoS requirements as best possible for each data flow set and associated physical resource partition.

Parallel data streams may be obtained from one or more radio bearers with common or different QoS requirements, and thus two or more data streams 209<sb>1</sb> to 209<sb>N</sb>) may have compatible QoS requirements. For example, Internet Protocol Voice over IP (VoIP) and Internet browsing data that require incompatible QoS may have different data streams 209<sb>1</sb> to 209<sb>N</sb>) or data stream sets, and mapped to separate physical resource partitions to best match different priority and delay requirements.

<b>Determining Send Attributes</b>

TFC selection function (210<sb>1</sb> to 210<sb>N</sb>) is preferably the corresponding data stream 209<sb>1</sb> to 209<sb>N</sb>) is driven in parallel to determine the TF and physical transmission attributes applied to each physical resource partition to optimally satisfy the QoS requirements of . This determination is preferably based on the CQI and dynamic scheduling information of each subchannel partition and the corresponding data stream 209<sb>1</sb> to 209<sb>N</sb>) based on the QoS requirements. Physical properties include modulation and coding rate, number of subframes per TTI, transmit power and HARQ retransmission that can be adjusted to meet the QoS requirements of each data flow and possibly adjusted along the CQI of a specific subchannel. . The HARQ process is preferably dynamically allocated to the physical resource partition, which will be described in more detail later.

One or more physical resource partitions may be associated with data streams with common QoS requirements. In this case, if the CQI is changed across each physical resource partition, the transmission format parameters including modulation and coding set (MCS), TB size, TTI length, transmit power and HARQ parameters determine QoS across subchannel partitions. adjusted to standardize. In other words, the data stream 209<sb>1</sb> to 209<sb>N</sb>), different parameters may be assigned for each physical resource partition to standardize the QoS on the corresponding data stream, which may be any subset of . For example, in the case where both MCS and transmit power affect the expected block error rate, if some TF attributes affect the same QoS attribute, some TF attributes may be adjusted relative to each other.

Once the coding, modulation and TTI lengths are associated with the physical resource partitions, transport blocks (TBs) (or, equivalently, sets of TBs) are allocated. In particular, the number of data bits that can be multiplexed into each TB for each subchannel partition is preferably determined based on different TF parameters. There may be multiple TBs with uniquely defined sizes in association with different physical resource partitions and HARQ processes. In the case where dynamic HARQ resource partitioning is allowed, the sum of the subchannel set transmission capabilities may not exceed the total available HARQ resources. If dynamic HARQ resource partitioning is not allowed, the selected TF may not exceed the resources available for each associated HARQ process.

For transmission over a physical channel, associated TF attributes 230<sb>1</sb> to 230<sb>N</sb>) with TB(250<sb>1</sb> to 250<sb>N</sb>) is provided in the physical layer.

<b>HARQ assignment</b>

According to a preferred embodiment, HARQ resources are dynamically distributed across physical resource partitions and their associated TBs (or equivalently, a set of TBs) so that multiple HARQ processes can be allocated before each TTI. This is preferable for the statically configured HARQ process resource proposed by the prior art, because when the static HARQ process resource is applied, the physical resource partition is limited to match the HARQ resource associated with it.

Since the entire HARQ resource can be dynamically divided as needed among the data multiplexed onto each physical resource partition, the dynamic distribution of HARQ resources can be much more flexible than during physical resource partitioning. Therefore, the partitioning of physical resources is not limited by the static resources of the associated HARQ process. Additionally, when the data of one upper layer radio bearer is distributed across multiple physical resource partitions providing different channel qualities, it is necessary to select the size of each TB and the MCS associated with the physical resource partition to supply the desired QoS. is much more flexible than in

Each TB associated with one or more sets of subchannels is assigned to an available HARQ process. If dynamic HARQ resource partitioning is allowed, the TB size and MCS allocated to the TB are preferably used to determine the soft memory requirements, and then used by the transmitter and receiver to identify the HARQ resources needed. For example, the information of the Transport Format Combination Indicator (TFCI) or Transport Format and Resource Indicator (TFRI) and the selected MCS at the receiver is generally sufficient for the receiver to dynamically reserve HARQ memory resources per TTI. In synchronous operation, the retransmission is known. In asynchronous operation, the HARQ process identifier is used to indicate retransmission. Preferably, when a retransmission occurs, the HARQ resource is not dynamically adjusted for retransmission because the resource requirements do not change from the initial transmission.

HARQ process (240<sb>1</sb> to 240<sb>N</sb>) is assigned to each TB and its associated physical resource partition. As a non-limiting example, information 230 including MCS, subframe, TTI, subcarrier or channelization code, antenna (in MIMO), antenna power, and maximum number of transmissions.<sb>1</sb> to 230<sb>N</sb>) is then given to the HARQ process for transmission. Then the HARQ process (240<sb>1</sb> to 240<sb>N</sb>) will indicate its availability upon receipt of a successful transmission acknowledgment, or upon exceeding its maximum number of retransmissions.

<b>data multiplexing</b>

Data multiplexer 220 provides TFC selection function 210<sb>1</sb> to 210<sb>N</sb>) provided by the TF attribute (215<sb>1</sb> to 215<sb>N</sb>) and data flow allocation information 214 , multiplex the upper layer data 204 . The data blocks in each data flow are multiplexed to the previously determined associated TB size. data flow (209<sb>1</sb> to 209<sb>N</sb>), the information of the physical support partition delivered after this is not required in multiplexing; Only TB size and data flow (209<sb>1</sb> to 209<sb>N</sb>) for logical channel 204<sb>1</sb> to 204<sb>M</sb>) is required. Preferably, the data flow 209<sb>1</sb> to 209<sb>N</sb>) logical channel 204 to the TB assigned to<sb>1</sb> to 204<sb>M</sb>) of the logical channel 204<sb>1</sb> to 204<sb>M</sb>) in order of priority.

If there is available data smaller than the TB size or multiplexing block size that does not fit exactly, the TB may be padded accordingly. However, the TFC selection process (210<sb>1</sb> to 210<sb>N</sb>) preferably eliminates the need for padding in most cases. If the available data for transmission exceeds the TB size and more than one TB has been determined for the set of associated data flows, then blocks from the associated data flow are distributed across the TBs. Within each TB, MAC header information specifies how data flows are multiplexed within each TB. This information uniquely identifies how data from different flows is multiplexed into a common TB, and how data from flows is distributed across the TB.
