METHOD FOR TRANSMISSION OF FIRST CHANNEL AND SECOND CHANNEL IN TRANSMISSION SCHEME OF MOBILE COMMUNICATION SYSTEM MODE AND METHOD FOR TRANSMISSION OF CONTROL CHANNEL

Technical Field

The present invention relates to a mobile communication system, and more particularly to a method for transmitting a control channel in a mobile communication system.

Basis of the Technique

In uplink transmission, that is, in the case where a user device acts as a transmitter, several methods for controlling power such as the capacity of a battery is increased or the power consumption of the user device is decreased to increase the duration of the user equipment have been suggested. Examples of methods for controlling power may include a discontinuous transmission scheme.

The transmission scheme batching can be, for example, a method to instantly reduce a data transmission output or adjust a silent state when a voice signal is not transmitted on a mobile phone or a portable cordless phone. When two people talk on the phone, the talk time for each of the two people is equal to or less than half of the total talk time. Thus, if the connection to a transmitter is established only during a voice input time, a transmission time can be reduced to 50% or less. In this way, the advantages including conserving battery power, reducing a load from a transmitter amplifier, and sharing the channel with another signal due to time division multiplexing (TDM) can be obtained.

Best Way to Carry Out the Invention

In the following, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention will be more fully understood from the detailed description provided below and accompanying drawings which are given by way of illustration only, and do not limit the present invention. The following detailed description includes details in order to provide a complete understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be incorporated without the details. For example, in the following description, specific terms are used, but the present invention is not limited to these terms.

In some cases, known structures and devices are omitted in order to avoid ambiguity in the concept of the present invention or the main functions of the structures and devices are shown in a block diagram and / or a flow chart. The same reference numbers will be used in all drawings to refer to the same or similar parts.

FIG. 1 is a drawing illustrating a compressed mode transmission scheme.

FIG. 1 shows a schematic frame structure according to with the compressed mode transmission scheme. According to the compressed mode transmission scheme, either one frame or two continuous frames is used as a compressed frame including the compressed mode (CM) gap in one frame or between two continuous frames. That is, some cracks in a frame that are determined to be used as the compressed frame, that is, cracks included in the CM gap, are not used in data transmission. These slots are used to perform an operation to interrupt the transmission / reception of data in the CM gap and the search for a neighboring cell and a neighboring network.

In order to reduce the influence of a reduced processing gain due to the existence of the CM gap and to maintain the quality of the communication, data can be transmitted in a state of transmission power

5/14 increasing with respect to some cracks in the compressed frame. As shown in FIG. 1, the slots for the transmission Data transmission with increased transmission power is found preferably before the CM gap is started and after the CM gap is closed. The amount of increased power in some cracks in the compressed frame can be determined by reducing the transmission time. Examples of a factor for measuring communication quality may include a bit error rate (BER) and a frame error rate (FER).

In a network, it can be determined which frame is used as the compressed frame. The compressed frame can be generated periodically in the compressed mode and can be generated by an order if necessary. The rate and type of the compressed frame can be determined by the requirements due to the various environments and measures of the channel.

Then, a uplink discontinuous transmission (DTX) scheme will be described as another method for controlling power. In a communication system, to reduce the energy consumption of a battery of a user equipment and to increase the capacity of the uplink channel, a batch transmission operation is designed on the uplink transmission. That is, the user equipment discontinuously transmits the data. By virtue of user equipment, a method for differently controlling power according to an interval in which data is transmitted and an interval in which data is not transmitted, that is, the DTX interval, is used.

For example, if the DTX interval is used, data is not always transmitted. In this way, when data is transmitted, the user equipment is in a state of use or in a state ON and, when data is not transmitted, the user equipment is in a state of minimization of energy consumption, such as a STANDBY state or an OFF state.

If the uplink discontinuous transmission scheme and the compressed mode transmission scheme are operated simultaneously once, a precise operation of the user equipment is examined instead. Next, the operation of the user equipment according to the modalities of the present invention when the uplink compressed mode transmission scheme and the uplink discontinuous transmission scheme are applied simultaneously will be described in detail.

First, the operation of the user equipment associated with the channel

6/14 expanded dedicated (E-DCH), according to an embodiment of the present invention will be described.

FIG. 2 is a drawing to illustrate a discontinuous transmission operation of the E-DCH.

Referring to FIG. 2, the E-DCH is a channel for transmitting uplink data packets and is mapped to a physical channel, such as an expanded dedicated physical data channel (E-DPDCH) and an expanded dedicated physical control channel (E- DPCCH). The E-DPDCH is the physical channel that is used to transmit data from the E-DCH and the E-DPCCH is the physical channel that is used to transmit control information associated with the E-DCH. In general, E-DPDCH and E-DPCCH are transmitted simultaneously.

When E-DCH is transmitted via E-DPDCH and E-DPCCH, to allow for a receiving side, for example, a B-node, to easily perform demodulation of the E-DCH using E-DCH detection or estimation channel, a dedicated physical control channel (DPCCH) is also transmitted. More specifically, the control information generated in a first layer is transmitted through the DPCCH. For example, at least one feedback information (FBI), transmitted power control command (TPC) and transport format combination indicator (TFCI), including an uplink pilot to support channel estimation can be transmitted.

However, control information that is not transmitted via the DPCCH, that is, the control information that is characteristic on the E-DCH, can be transmitted through through the E-DPCCH as the control information used in the demodulation of the E-DCH. For example, TFCI, HARQ information and schedule request information can be transmitted via EDPCCH. At this time, E-DPDCH, E-DPCCH and DPCCH can be transmitted simultaneously and are multiplexed using different codes or different orthogonal phase components.

As shown in FIG. 2, the user equipment starts transmitting the DPCCH before transmitting the E-DPDCH and E-DPCCH. In other words, transmission of the E-DPDCH and E-DPCCH is started at a predetermined time after the DPCCH transmission is initiated, or after a predetermined number of slots are transmitted. The DPCCH signal that is transmitted before the E-DPDCH and E-DPCCH are transmitted is called a DPCCH preamble. FIG. 3 shows a case where two slits are used as the preamble of the DPCCH. Next, the number of slots used as

7/14 preamble to the DPCCH is denoted by N.

The user equipment transmits the DPCCH at a predetermined time, after the transmission of the E-DPDCH and E-DPCCH is completed or after a predetermined number of slots is transmitted and then completes the transmission process of the E-DCH. The DPCCH signal that is transmitted after the transmission of the E-DPDCH and E-DPCCH is completed is called a DPCCH preamble. FIG. 2 shows a case where a slit is used as the post of the DPCCH. Next, the number of slots used as the DPCCH postambulo is denoted by M.

As described above, the preamble of the DPCCH and the preamble of the DPCCH are transmitted, respectively, before and after the E-DPDCH and E-DPCCH are transmitted such that the receiving side, for example, the B-node detects the EDCH, most likely to succeed.

In the preamble of the DPCCH, the number of slots used as the preamble of the DPCCH can be determined according to the data transmission status of the equipment. the user. For example, if the user does not transmit the data for a longer time than a predetermined time interval before transmitting the E-DCH, more slits can be used as the preamble of the DPCCH, compared to a case where the user does not transmit the data during the predetermined time interval, or less.

If the user does not transmit the data during the predetermined time interval or less, the number of slots Ni used as the preamble of DPCCH can be 2. In contrast, if the user does not transmit the data for a longer time than the interval of predetermined time, the number of slots N2 used as the preamble of the DPCCH can be 15. This is because, if the data is not transmitted for a longer time, it is preferable that the control information necessary for the uplink synchronization is transmitted and more control information necessary to perform the power control is transmitted.

As shown in FIG. 2, in the transmission of the DPCCH, as described above, the preamble of the DPCCH is transmitted by a predetermined number N of slots, for example, two slots, before transmitting the E-DPDCH and EDPCCH, and the DPCCH preamble is transmitted by a predetermined number of slits M, for example a slit, after transmission of EDPDCH and E-DPCCH. A process for transmitting the preamble of the DPCCH, transmitting the E-DPDCH and E-DPCCH, and transmitting the DPCCH preamble

8/14 is considered to be a transmission unit. A transmission unit shown on the left side of FIG. 2 is referred to as a first transmission unit and a transmission unit shown to the right of FIG. 2 is referred to as a second transmission unit.

In this case, a predetermined DTX interval can be adjusted between the first transmission unit and the second transmission unit. Data is not transmitted in the DTX range. If the DTX interval finished, the preamble of the DPCCH is transmitted again, the E-DCH, that is, the E-DPDCH and EDPCCH, is transmitted, and the DPCCH preamble is transmitted, thus concluding the data transmission from a transmission unit.

Now, a method for the transmission of the E-DCH by the user's equipment when the discontinuous transmission scheme and the compressed mode transmission scheme of the E-DCH are applied simultaneously will be described.

FIG. 3 is a drawing to illustrate the operation of the user equipment according to an embodiment of the present invention, when the compressed mode transmission scheme and the batch transmission scheme are applied simultaneously in the transmission of the E-DCH.

As described above, for E-DCH transmission, E-DPDCH and EDPCCH are transmitted and DPCCH is transmitted together with E-DPDCH and E-DPCCH. The DTX interval, according to the discontinuous transmission scheme, exists between the first unit of t transmission that is transmitted first and the second unit, which is the next transmitted.

That is, the transmission of data corresponding to the first transmission unit is completed and, after the DTX interval, the transmission of data corresponding to the second transmission unit is initiated, transmitting the preamble of the DPCCH.

At this point, as shown in FIG. 3, if a portion of the DPCCH preamble of the second transmission unit is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, the DPCCH preamble is not transmitted in one portion or all cracks overlapping the CM gap, but the E-DPDCH and E-DPCCH as well as the preamble of the remaining DPCCH, the DPCCH signal and the DPCCH preamble are transmitted in accordance with the embodiment of the present invention. If the DPCCH post is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, post d The

9/14

DPCCH is not transmitted from a portion or all cracks overlapping the CM, but the E-DPDCH and E-DPCCH as well as the preamble of the DPCCH, the DPCCH signal and the remaining DPCCH preamble are transmitted.

This is because an error check sum (ECS), for error verification can be used in the E-DCH data, a HARQ operation is performed, and the deterioration of the reception capacity due to the lack of the DPCCH preamble and DPCCH preamble in the receiving side can be easily recovered, although at least one of the DPCCH preamble and DPCCH preamble is determined to be transmitted in the CM gap and cannot be transmitted.

FIG. 4 is a drawing to illustrate the operation of the user equipment according to another embodiment of the present invention, when the compressed mode transmission scheme and the batch transmission scheme are applied simultaneously in the transmission of the E-DCH.

If the user equipment is not o transmitting data over a period of time longer than the predetermined time interval, as shown in FIG. 4, the number of slots N2 used as the preamble of the DPCCH can be adjusted to 15. This is because, as described, if the data is not transmitted for the longest time, it is preferable that the control information necessary for the uplink synchronization is transmitted and more control information necessary for carrying out power control is transmitted.

In the present embodiment, similar to the embodiment of FIG. 3, if a portion of the preamble of the long length DPCCH is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, the preamble of the long length DPCCH is not transmitted in one portion or all overlapping slits the CM gap, but the E-DPDCH and E-DPCCH as well as the preamble of the remaining DPCCH, the DPCCH signal and the DPCCH preamble are transmitted, according to the embodiment of the present invention.

Likewise, if the DPCCH post is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, the DPCCH post is not transmitted in one portion or all cracks overlapping the CM gap, but the E-DPDCH and E-DPCCH as well as the preamble of the DPCCH, the DPCCH signal and the remaining DPCCH preamble are transmitted.

10/14

FIG. 5 is a drawing to illustrate the operation of the user equipment according to another embodiment of the present invention, when the compressed mode transmission scheme and the batch transmission scheme are applied simultaneously in the transmission of the E-DCH.

In the present embodiment, unlike the modalities shown in Figs. 3 and 4, if a portion of the preamble of the long-length DPCCH is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, the DPCCH and the si remaining channel signals of the total transmission unit associated with the preamble of the long-length DPCCH, as well as the cracks overlapping the gaps in the CM are not transmitted according to the embodiment of the present invention. That is, all the remaining DPCCH preambles, the DPCCH signal, the DPCCH preamble, the E-DPDCH and E-DPCCH are not transmitted.

Likewise, if the DPCCH preamble is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, the DPCCH and the remaining channel signals of the total transmission unit associated with the DPCCH preamble, as well as the cracks overlapping the CM gap are not transmitted according to the embodiment of the present invention. That is, all DPCCH preambles, DPCCH signal, remaining DPCCH preamble, E-DPDCH and E-DPCCH are not transmitted.

The control information for uplink synchronization and the control information required for power control are transmitted via the preamble of the long-length DPCCH transmitted after the data is not transmitted during the predetermined time interval. Thus, if the preamble of the long-length DPCCH is not normally received, it is difficult to establish the uplink synchronization. In this case, a fatal error can occur in the transmission / reception of data.

Then, the operation of the user equipment associated with the discontinuous transmission of a dedicated high-speed physical control channel (HS-DPCCH) will be described as an embodiment of the present invention.

FIG. 6 is a drawing to illustrate a discontinuous transmission operation of the HS-DPCCH.

The HS-DPCCH sends an uplink return signal associated with the transmission of the shared high-speed downlink channel (HS-DSCH). The return signal associated with the HS-DSCH includes HARQ recognition (ACK / NACK) and

11/14 an indication of channel quality.

Wed n HS-DPCCH is transmitted, similar to EDCH, in order to allow the receiving side, for example, the B-node, to easily perform E-DCH demodulation using E-DCH detection or channel estimation, DPCCH is also transmitted. That is, the control information for the power control and the necessary control information, including a pilot for the channel estimation can be transmitted via the DPCCH. At this time, HSDPCCH and DPCCH can be transmitted simultaneously and are multiplexed using different codes or different orthogonal phase components.

As shown in FIG. 6, the user equipment starts transmitting the DPCCH before transmitting the HS-DPCCH. That is, the HSDPCCH transmission starts at a predetermined time, after the DPCCH transmission is initiated or a predetermined number of slots are transmitted. The DPCCH signal that is transmitted before the HS-DPCCH is transmitted is called a preamble DPCCH. FIG. 6 shows a case where two slits are used as the preamble of the DPCCH. Next, the number of slits used as the preamble of the DPCCH is denoted by N.

The user equipment transmits the DPCCH at a predetermined time, after the transmission of the HS-DPCCH is completed or after a predetermined number of slots are transmitted and then completes the transmission process of the HS-DPCCH. The DPCCH signal that is transmitted after the HS-DPCCH transmission is completed is called the DPCCH preamble. FIG. 6 shows a case where a slit is used as a post for the DPCCH. Next, the number of slots used as the DPCCH preamble is denoted by M.

As described above, the DPCCH preamble and the DPCCH preamble are transmitted, respectively, before and after the HS-DPCCH is transmitted so that the receiving side, for example, the B-node detects the HS-DPCCH most likely. Of success.

As shown in FIG. 6, in the transmission of the DPCCH, as described above, the preamble of the DPCCH is transmitted by the predetermined number N of slots, for example, two slots, before the transmission of the HS-DPCCH and the post of the DPCCH is transmitted by the predetermined number of slots , for example, a slit, after the transmission of the HS-DPCCH.

A process of transmitting the preamble to the DPCCH, transmitting the

12/14

HS-DPCCH, and DPCCH transmission is considered as a transmission unit. A transmission unit shown on the left side of FIG. 6 is referred to as a first transmission unit and a transmission unit shown to the right of FIG. 6 is referred to as a second transmission unit.

In this case, a predetermined DTX interval can be adjusted between the first transmission unit and the second transmission unit and the data is not transmitted in the DTX interval. If the DTX interval is ended, the DPCCH preamble is transmitted again. te, the DPCCH and HS-DPCCH are transmitted, and the DPCCH preamble is transmitted, thus terminating the data transmission from a transmission unit.

At this time, compared to the E-DCH discontinuous transmission scheme, while the E-DPDCH and E-DPCCH are transmitted from a slot immediately next to two slots, in which the preamble of the DPCCH is transmitted, in the transmission scheme discontinuous of the E-DCH, the HSDPCCH is transmitted from a middle portion of a slot immediately next to the slot, in which the preamble of the DPCCH is transmitted, in the discontinuous transmission scheme of the HS-DPCCH as shown in FIG. 6.

Even when transmitting the DPCCH post, while the E-DPDCH and E-DPCCH are transmitted to a slot immediately before a slot, in which the DPCCH post is transmitted, in the E-DCH discontinuous transmission scheme, the HS -DPCCH is transmitted to a middle portion of a crack immediately before a crack, in which the DPCCH preamble is transmitted, in the HS-DPCCH discontinuous transmission scheme as shown in FIG. 6.

Now, a method for the transmission of the HS-DPCCH by the user equipment when the discontinuous transmission scheme and the compressed mode transmission scheme of the HS-DPCCH are applied simultaneously will be described.

FIG. 7 is a drawing to illustrate the operation of user equipment according to one embodiment of the present invention, when the compressed mode transmission scheme and the discontinuous transmission scheme are applied simultaneously in the transmission of the HS-DPCCH.

As described above, for the transmission of the HS-DPCCH, the HS-DPCCH is transmitted and the DPCCH is transmitted together with the HS-DPCCH. The DTX interval according to the discontinuous transmission scheme exists between the

13/14 first transmission unit that is transmitted first and the second transmission unit that is the next transm itida.

That is, the transmission of data corresponding to the first transmission unit is completed and, after the DTX interval, the transmission of data corresponding to the second transmission unit is initiated by the transmission of the preamble of the DPCCH.

At that time, if a portion of the DPCCH preamble of the second transmission unit is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, the DPCCH preamble is not transmitted in one portion or all cracks overlapping the gap CM gap, but the HS-DPCCH as well as the preamble of the remaining DPCCH, the DPCCH signal and the DPCCH preamble are transmitted, according to the embodiment of the present invention.

If the DPCCH post is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, the DPCCH post is not transmitted in one portion or all cracks overlapping the CM gap, but the HS-DPCCH well c As the preamble of the DPCCH, the signal of the DPCCH and the preamble of the remaining DPCCH are transmitted.

FIG. 8 is a drawing to illustrate the operation of user equipment according to another embodiment of the present invention, when the compressed mode transmission scheme and the discontinuous transmission scheme are applied simultaneously in the transmission of the HS-DPCCH.

In the present embodiment, unlike the embodiment shown in FIG. 7, if a portion of the DPCCH preamble is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, the DPCCH and the remaining channel signals of the total transmission unit associated with the DPCCH preamble, as well as the cracks overlapping the CM gap are not transmitted according to the embodiment of the present invention.

Likewise, if the DPCCH postamble is determined to be transmitted in the CM gap according to the compressed mode transmission scheme, the DPCCH and the remaining channel signals from the total transmission unit associated with the preamble of the DPCCH, as well as the cracks overlapping the CM gap are not transmitted according to the embodiment of the present invention. That is, all DPCCH preambles, DPPCCH signal, remaining DPCCH preamble and HS-DPCCH are not transmitted.

This is because the ECS to check the error cannot be applied to the data of the

14/14

HS-DPCCH and the HARQ operation cannot be performed. Thus, if at least one DPCCH preamble and DPCCH preamble is transmitted in the CM gap and therefore cannot be transmitted, a likelihood of deterioration of the reception capacity, due to the lack of the DPCCH preamble and DPCCH pram on the side reception is high.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention encompasses the changes and variations of the present invention, provided they are within the scope of the appended claims and their equivalents. Although the examples that are applied when E-DPDCH / E-DPCCH and HS-DPCCH are transmitted together with DPCCH are described in the modalities described above, it will be apparent to those skilled in the art that a method equal to or similar to the transmission method described in the present specification it can be used with respect to several other channel signals.

The present invention is not limited to the modalities described herein and includes a wide range, including the principles and characteristics described herein.
