Description

TECHNICAL FIELD [0001] The present invention relates to a method and an apparatus for transferring control information in a carrier integration system,

The present invention relates to a cellular wireless communication system, and more particularly, to a method and apparatus for transmitting a control channel in a carrier aggregation system.

Generally, a mobile communication system has been developed to provide voice service while ensuring the user's activity. However, the mobile communication system is gradually expanding not only to voice but also to data service, and now it has developed to the extent of providing high-speed data service. However, in a mobile communication system in which services are currently being provided, there is a demand for a more advanced mobile communication system due to a shortage of resources and a high-speed service demand of users.

A Long Term Evolution-Advanced (LTE-A) system based on the Long Term Evolution (LTE) system in the 3GPP (Third Generation Partnership Project) Communication. LTE-A supports a carrier aggregation system that can communicate with a base station by using a number of carriers by expanding the number of cells to which the terminal connects, and all cells extended to the terminal are duplexed, Structure. Therefore, all the cells may have a frequency division duplex (FDD) structure or a time division duplex (TDD) structure. The TDD may be a static TDD structure in which the UL-DL configuration is maintained, and may be a dynamic TDD structure in which the UL-DL setting is changed by system information or an upper signal or a downlink common control channel.

If one cell controlled by the base station has an FDD structure and one frequency band is added, the one frequency band is easy to apply the TDD structure. This is because two different frequency bands are required for the downlink (DL) and the uplink (UL) to operate the FDD. Therefore, if the duplex structure is different between cells due to the addition of a limited frequency band or other reasons as described above, a scheme for transmitting a control channel for data transmitted from a plurality of cells is needed.

In addition, LTE-A adopts a method of extending the number of cells to which a UE connects and transmitting feedback generated in each cell only in a primary cell or a Pcell. In addition, when a terminal capable of supporting only one carrier in the uplink and a terminal capable of supporting a plurality of carriers in the uplink coexist, only a single uplink carrier can be used for a terminal capable of supporting only one uplink carrier And transmit the uplink control channel. Therefore, there is not a large number of terminals capable of supporting a plurality of carriers in a base station, and a method of transmitting only the feedback generated in the downlink of each cell in the P cell in terms of defining a standard for supporting all terminals is adopted. When the uplink control channel transmission and the uplink data channel transmission occur in the same subframe in the LTE-A, the uplink control information transmitted in the uplink control channel is embedded in the uplink data channel and transmitted.

However, when the number of UEs supporting a plurality of uplink carriers increases, it is necessary to support uplink control channel transmission in a plurality of uplink carriers. Also, since a plurality of uplink control channel transmissions occur, There is a need for a technique for inserting uplink control information transmitted in a plurality of uplink control channels into an uplink data channel and transmitting the same.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-mentioned problems, and one embodiment of the present invention is to provide a method and apparatus for transmitting uplink control channel transmission in a case where a plurality of uplink carriers support uplink control channel transmission in a carrier aggregation system, It is another object of the present invention to provide a method and apparatus for transmitting uplink control information in an uplink data channel when data channel transmission occurs in the same subframe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and these may be changed according to the intention of the user, the operator, or the like. Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, embodiments of the present invention will be described by taking LTE system and LTE-A system as an example, but the present invention can be applied to other communication systems to which base station scheduling is applied without adding or subtracting it.

An OFDM (Orthogonal Frequency Division Multiplexing) transmission scheme is a scheme for transmitting data using a multi-carrier, in which symbol streams input in series are parallelized, and each of them is mutually orthogonal Carrier modulation scheme in which a plurality of subcarriers are modulated with a plurality of subcarriers, that is, a plurality of subcarrier channels.

In the OFDM scheme, a modulated signal is located in a two-dimensional resource composed of time and frequency. The resources on the time axis are distinguished by different OFDM symbols and they are orthogonal to each other. The resources on the frequency axis are distinguished by different subcarriers and they are also orthogonal to each other. That is, in the OFDM scheme, when a specific OFDM symbol is designated on the time axis and a specific subcarrier is designated on the frequency axis, it can be referred to as a resource element (RE). Different REs have characteristics that are orthogonal to each other even though they pass through a frequency selective channel, so that signals transmitted through different REs can be received at the receiving side without mutual interference.

A physical channel is a channel of a physical layer for transmitting a modulation symbol modulating one or more encoded bit streams. In an Orthogonal Frequency Division Multiple Access (OFDMA) system, a plurality of physical channels are configured and transmitted according to the use of an information sequence to be transmitted or a receiver. A transmitter and a receiver have to promise in advance which RE to place a physical channel to transmit, and the rule is called mapping.

In the OFDM communication system, a downlink bandwidth consists of a plurality of resource blocks (RBs), and each physical resource block (PRB) 12 subcarriers arranged along the time axis and 14 or 12 OFDM symbols arranged along the time axis. Here, the PRB is a basic unit of resource allocation.

A reference signal (RS) is a signal transmitted from a base station. The terminal estimates the channel using the RS. The LTE communication system includes a common reference signal (CRS) and a demodulation reference signal (DMRS). The DMRS is a kind of dedicated reference signal.

CRS is a reference signal transmitted over the entire downlink band. All terminals can receive CRS. The CRS is used for channel estimation, feedback information configuration of the UE, or demodulation of control channels and data channels. The DMRS is also a reference signal transmitted over the entire downlink band. The DMRS is used for data channel demodulation and channel estimation of a specific terminal and unlike the CRS, it is not used for feedback information configuration. Therefore, the DMRS is transmitted through the PRB resource to be scheduled by the UE.

A subframe on the time axis is composed of two slots having a length of 0.5 msec, that is, a first slot and a second slot. A physical downlink control channel (PDCCH) region, which is a control channel region, and an enhanced PDCCH (ePDCCH) region, which is a data channel region, are divided and transmitted on a time axis. This is for quickly receiving and demodulating control channel signals. In addition, the PDCCH region is located over the entire downlink band, and one control channel is divided into a small number of control channels and distributed in the entire downlink band.

The uplink is divided into a physical uplink control channel (PUCCH) and a physical uplink data channel (PUSCH). When the uplink data channel is not scheduled, a response to the downlink data channel (HARQ-ACK feedback) and other feedback information such as channel information are transmitted through the control channel. When the uplink data channel is scheduled, other feedback information such as a response to the downlink data channel (HARQ-ACK feedback) and channel information is transmitted through the data channel.

1A and 1B illustrate a communication system to which some embodiments of the present invention are applied. Referring to FIG. 1A, a cell 1 102 and a cell 2 103 coexist in one base station 101 in a network. The cell 1 may be a TDD cell or an FDD cell. Cell 2 may be a TDD cell or an FDD cell. The terminal 104 transmits data to and receives data from the base station via the cell 1 102 and the cell 2 103. The UE 104 may transmit the uplink control channel through a plurality of uplink carriers or the uplink control channel through one uplink carrier according to the capability of the corresponding terminal. When the UE 104 has the capability of transmitting an uplink control channel through a plurality of uplink carriers, the UE performs uplink transmission through the cell 1 102 and the cell 2 103. When the UE 104 has the capability of transmitting the uplink control channel through one uplink carrier, the UE 104 performs the uplink transmission only through the P-cell. When the cell # 1 102 is a P cell, the UE 104 performs uplink transmission only through the cell # 1 102. Also, when the cell # 2 103 is a P cell, the UE 104 performs uplink transmission only through the cell # 2 103.

Referring to FIG. 1B, a macro base station 111 for wide coverage and a Pico base station 112 for increasing data transmission amount coexist in the network. 1B, the macro base station 111 can use the FDD scheme in the second cell 116 and the pico base station 112 can perform communication with the MS 114 in the first cell 115 using the TDD scheme . Alternatively, the macro base station 111 may use the TDD scheme in the second cell 116, and the pico base station 112 may communicate with the MS 114 in the first cell 115 using the FDD scheme. The UE 114, which can transmit the uplink control channel through a plurality of uplink carriers, can transmit the uplink control channel through a plurality of uplink carriers and the uplink control channel through one uplink carrier have. When the UE 114 transmits the uplink control channel through a plurality of uplink carriers, the UE performs uplink transmission through the pico base station 112, which is a TDD scheme, and the macro base station 111, which is an FDD scheme. When the UE 114 transmits the uplink control channel through one uplink carrier, if the macro base station is a P cell, the UE performs uplink transmission only through the macro base station 111. If the pico base station is a P-cell, the terminal performs uplink transmission only through the pico base station 112. [ In this case, it is assumed that the macro base station 111 and the pico base station 112 have an ideal backhaul network. Therefore, even if the uplink signal of the terminal 114 is transmitted only to the macro base station 111 or the pico base station 112, it is possible to perform the X2 communication 113 between the base station 111 and the terminal 114 through the X2 communication 113, It is possible to receive the control information associated with the P-cell base station from the P-cell base station in real time.

Although the method proposed by some embodiments of the present invention is applicable to both the system of FIG. 1A and the system of FIG. 1B, the present invention will mainly be described on the assumption of the system of FIG.

Next, referring to FIG. 2, the present invention will be described with respect to cells capable of performing HARQ-ACK feedback and channel information reporting in an uplink control channel.

FIG. 2A illustrates an example of cells mapped to a conventional uplink control channel. Conventionally, carrier aggregation in LTE-A is possible up to five cells. One cell capable of transmitting uplink control information is referred to as a P cell, and the remaining cells are referred to as a secondary cell or a scell (S cell) The S-cell has an S-cell index (SCellIndex). The HARQ-ACK feedback and channel information for each of the five cells are always transmitted only through the PUCCH in the P-cell. In FIG. 2A, a cell (P cell) indicated by hatching means a cell transmitting a PUCCH. For example, the HARQ-ACK feedback for the downlink data transmitted in the S-cell 1 is transmitted through the PUCCH of the P-cell, and the channel information measured in the S-cell 1 is transmitted through the PUCCH of the P-cell according to the reporting period set in the S- . Therefore, the mapped cells are allocated to five cells (P cell, S cell 1, S cell 2, S cell 3, and S cell 5) including the P cell so as to perform HARQ-ACK feedback and channel information reporting on the PUCCH in the P cell. 4, S-cell 5).

 FIG. 2B shows a first embodiment of cells mapped to a plurality of uplink control channels proposed in the present invention. The first embodiment shown in FIG. 2B can accumulate carriers up to 5 cells as in carrier integration in the conventional LTE-A, but it is possible to group cell groups capable of transmitting HARQ-ACK feedback and channel information through PUCCH, . Cells (P-cell, S-cell 1) indicated by hatching in FIG. 2B mean cells transmitting PUCCH. Cell group 1 (201) is a set of cells to be mapped so that HARQ-ACK feedback and channel information reporting can be performed through PUCCH in P-cell. In the first embodiment of FIG. 2B, the cell group 1 (201) includes three cells of P cell, S cell 2, and S cell 3 in total. The cell group 2 202 is a set of cells to be mapped so as to perform HARQ-ACK feedback and channel information reporting on the PUCCH in the S-cell 1. In the first embodiment shown in FIG. 2B, the cell group 2 202 includes two cells of S cell 1 and S cell 4 in total. Therefore, it can be seen that the mapped cells for the HARQ-ACK feedback and the channel information reporting through the PUCCH in the P cell are the P cell, the S cell 2, and the S cell 3 included in the cell group 1 201, and S It can be seen that the cells mapped to enable HARQ-ACK feedback and channel information reporting through the PUCCH in cell 1 are S cell 1 and S cell 4 included in cell group 2 202. [

FIG. 2C illustrates a second embodiment of cells mapped to a plurality of uplink control channels proposed in the present invention. The second embodiment shown in FIG. 2C can accumulate carriers up to five cells as in the conventional carrier aggregation in LTE-A, but it is possible to group cell groups capable of transmitting HARQ-ACK feedback and channel information through PUCCH, . Cells (P cell, S cell 4) indicated by hatching in FIG. 2C indicate cells transmitting PUCCH. The cell group 1 (211) is a set of cells to be mapped so as to perform HARQ-ACK feedback and channel information reporting on the PUCCH in the P-cell. In the second embodiment of FIG. 2C, a total of four cells of P cell, S cell 1, S cell 2, and S cell 3 are included in cell group 211. The second cell group 212 is a set of cells to be mapped so as to perform HARQ-ACK feedback and channel information reporting on the PUCCH in the S-cell 4. [ In the second embodiment of FIG. 2C, only the S cell 4 is included in the cell group 212 (212). Accordingly, it can be seen that the mapped cells for the HARQ-ACK feedback and the channel information reporting through the PUCCH in the P cell are the P cell, the S cell 1, the S cell 2, and the S cell 3 included in the cell group 1 211 And the mapped cells for the HARQ-ACK feedback and the channel information reporting through the PUCCH in the S-cell 4 are only the S-cell 4 included in the cell group 2 212. [

FIG. 2D shows a third embodiment of cells mapped to a plurality of uplink control channels proposed in the present invention. The third embodiment of FIG. 2D can accumulate carriers up to five cells as in carrier integration in the conventional LTE-A. However, it is possible to group cell groups capable of transmitting HARQ-ACK feedback and channel information through a PUCCH into separate groups . Cells (P cell, S cell 2) indicated by hatching in FIG. 2D refer to cells transmitting PUCCH. The cell group # 1 221 is a set of cells to be mapped so as to perform HARQ-ACK feedback and channel information reporting through the PUCCH in the P-cell. In the third embodiment of FIG. 2D, only the P cell is included in the cell group 221 (221). Cell group 2 222 is a set of cells to be mapped so as to perform HARQ-ACK feedback and channel information reporting on the PUCCH in S-cell 2. In the third embodiment of FIG. 2D, the cell group 2 222 includes four cells of S cell 1, S cell 2, S cell 3, and S cell 4 in total. Therefore, it can be seen that the mapped cells for performing HARQ-ACK feedback and channel information reporting through the PUCCH in the P-cell are only the P-cells included in the cell group 221, and the HARQ- It can be seen that the mapped cells for the -ACK feedback and the channel information reporting are the S cell 1, the S cell 2, the S cell 3, and the S cell 4 included in the cell group 2 (222).

For the sake of convenience, a P cell in which PUCCH is transmitted in cell group 1, and a cell in which PUCCH is transmitted in cell group 2 are referred to as pS cells.

Next, when a PUCCH transmission and a PUSCH transmission based on a cell group mapped to a plurality of PUCCHs in FIGS. 2B, 2C and 2D occur in the same subframe, the uplink control information of the PUCCH is transmitted to the PUSCH And then transmitting the data. 3, 4, and 5, a method of transmitting uplink control information by inserting the uplink control information into the PUSCH independently for each cell group is proposed. That is, when a plurality of cell groups are set in the UE for carrier integration, even if the PUSCH is transmitted in the cells of the cell group 1, the PUSCH is not transmitted in the cells of the cell group 2, and only the PUCCH is transmitted in the pS cell, The control information of the PUCCH of the pS cell of 2 is inserted into the PUSCH transmitted in the cells of the cell group 1 and is not transmitted.

The PUCCH transmission and the PUSCH transmission can be performed for each cell group. Therefore, when the UE uplink power control is performed, the power scaling order can be interlocked with the uplink control information type of the PUCCH transmission and the PUSCH transmission. For example, when HARQ-ACK feedback is inserted in the PUSCH of the cell group 1 and channel information is transmitted to the PUCCH of the cell group 2, the PUCCH transmission power of the cell group 2 may be scaled first when the power of the UE is limited have. As another example, when channel information is inserted in the PUSCH of the cell group 1 and HARQ-ACK feedback is transmitted to the PUCCH of the cell group 2, when the power of the UE is limited, the transmission power of the PUSCH of the cell group 1 is scaled .

The method proposed by the present invention will be specifically described as follows.

If simultaneous transmission of PUCCH and PUSCH is not set to the UE in the cell in which the PUCCH is transmitted, and simultaneous transmission of PUCCH and PUSCH in the cell in which the PUCCH is transmitted is set to the UE, then only P- PUSCH simultaneous transmission is set to the UE. Hereinafter, simultaneous transmission of PUCCH and PUSCH means that PUCCH and PUSCH are transmitted using the same cell in the same subframe. When PUCCH and PUSCH are overlapped, PUCCH and PUSCH are transmitted using the same or different cells in the same subframe. .

Whether the terminal supports the cell group operation is determined by the UE capability for performing the PUCCH transmission operation in a plurality of cells. When the terminal accesses the network, the terminal reports its terminal capability to the network do. The cell group operation refers to an operation of setting cells included in a plurality of cell groups and cell groups in the carrier aggregation system and inserting and transmitting uplink control information of the PUCCH in the PUSCH according to the cell group. When the terminal capability supports the cell group operation, the network can inform the terminal of cell group configuration information such as the number of cell groups and which cell belongs to the cell group through higher layer signaling.

In addition, a terminal capable of simultaneously transmitting PUCCH and PUSCH may be set or not to enable simultaneous transmission through upper layer signaling.

First, the operation of inserting and transmitting uplink control information will be described when the PUCCH and the PUSCH are not simultaneously transmitted to the UE in the PUCCH-transmitted cell. That is, when PUCCH and PUSCH simultaneous transmission are not set in P cell or pS cell, when PUCCH transmission and PUSCH transmission occur in the same subframe, a method of inserting PUCCH uplink control information into PUSCH and transmitting is described. If the PUCCH and PUSCH are not simultaneously transmitted to the UE, the PUCCH and the PUSCH can be simultaneously transmitted to the UE that can not simultaneously transmit the PUCCH and the PUSCH. However, the PUCCH and the PUSCH may not be simultaneously transmitted to the UE .

First, if the cell group 1 includes more than one cell, if the P-cell transmits the PUCCH, the uplink control information insertion is determined based on the PUSCH transmission in the cell group 1 and the type of the UL control information. For example, when a PUSCH transmission occurs in the cell due to a request for transmission of aperiodic channel information for a cell belonging to cell group 1, the uplink control information of the PUCCH transmitted in the P-cell is transmitted as non-periodic channel information or HARQ- The uplink control information is inserted in the PUSCH due to the aperiodic channel information request of the cell and transmitted. As another example, if a PUSCH transmission occurs in a P-cell, if the uplink control information of the PUCCH transmitted in the P-cell is periodic channel information or HARQ-ACK feedback, the uplink control information is inserted into the PUSCH of the P- And transmitted. As another example, when a PUSCH transmission occurs in an S cell of a cell group 1 other than a P cell, if the uplink control information of the PUCCH transmitted in the P cell is periodic channel information or HARQ-ACK feedback, Is inserted in the PUSCH of the S cell having the smallest S cell index among the S cells of the cell group 1 transmitting the PUSCH and is transmitted. The above insertion and transmission operations are applied in the same manner even when the cell group 2 includes one or more cells, and when the pS cell transmits the PUCCH, insertion of the uplink control information is determined based on the PUSCH transmission in the cell group 2 do.

Next, if the cell group 1 includes only one cell (i.e., the P cell), if the P cell transmits the PUCCH, then if the PUSCH transmission occurs in the cell group 1, unconditional uplink control information insertion is determined. For example, when a PUSCH transmission in a cell belonging to cell group 1 occurs in the same subframe, uplink control information of a PUCCH transmitted in the P cell is inserted in the PUSCH and transmitted. The above insertion and transmission operations are applied in the same manner even when the cell group 2 includes only one cell (i.e., pS cell), and if the pS cell transmits a PUCCH, the uplink control Information insertion is determined.

3, when the uplink control channel and the uplink data channel are not simultaneously transmitted in the cell where the uplink control channel is transmitted and the uplink control channel overlaps with the uplink data channel, The operation of the base station and the terminal for the insertion will be described.

FIG. 3A is a flowchart showing a base station operation. FIG. First, in step 301, the base station does not set the simultaneous PUCCH and PUSCH transmission in the PUCCH transmission cell of the cell group (P cell in cell group 1, pS cell in cell group 2). If the simultaneous transmission of the PUCCH and the PUSCH is not performed in the UE, the PUCCH and the PUSCH can be simultaneously transmitted to the UEs that can not simultaneously transmit the PUCCH and PUSCH. However, . If it is determined in step 302 that the PUCCH reception and the PUSCH reception conflict in the subframe n, that is, the subframe in which the PUCCH is to be received from the terminal and the subframe in which the PUSCH is to be received from the terminal coincide with each other, (I.e., cell group 1 if the PUCCH transmission cell is a P-cell and cell group 2 if the PUCCH transmission cell is a pSCH) includes one or more cells or only one cell. If the cell group transmitting the PUCCH includes more than one cell in step 303, the uplink control information is transmitted to the PUSCH based on the situation of the PUSCH transmission in the cell group proposed in the present invention and the type of the UL control information, The uplink control information is extracted from the received PUSCH. If the PUCCH transmission in the cell group proposed by the present invention occurs in step 305, if the cell group transmitting the PUCCH includes only one cell in step 303, the method of inserting the uplink control information into the PUSCH unconditionally includes the uplink control information And extracts it from the received PUSCH.

3B is a flowchart showing a terminal operation. First, in step 311, the UE does not set up the simultaneous PUCCH and PUSCH transmission in the PUCCH transmission cell of the cell group (P cell in cell group 1, pS cell in cell group 2). If the simultaneous transmission of the PUCCH and the PUSCH is not performed in the UE, the PUCCH and the PUSCH can be simultaneously transmitted to the UEs that can not simultaneously transmit the PUCCH and PUSCH. However, . If it is determined in step 312 that the PUCCH transmission and the PUSCH transmission conflict in the subframe n, that is, the subframe in which the UE transmits the PUCCH matches the subframe in which the UE transmits the PUSCH, the UE determines in step 313 that the cell group The cell group 1 if the PUCCH transmission cell is a P cell, and the cell group 2 if the PUCCH transmission cell is a pS cell) includes one or more cells or only one cell. If the cell group transmitting the PUCCH includes more than one cell in step 313, the uplink control information is transmitted to the PUSCH based on the situation of the PUSCH transmission in the cell group proposed in the present invention and the type of the uplink control information, And inserts the uplink control information into the PUSCH and transmits the same. If the cell group transmitting the PUCCH includes only one cell in step 313, if the PUSCH transmission in the cell group proposed in the present invention occurs in step 315, the method of inserting the uplink control information into the PUSCH unconditionally includes the uplink control information PUSCH for transmission.

Second, the operation of inserting and transmitting uplink control information when the PUCCH and the PUSCH are concurrently transmitted to the UE in a cell in which the PUCCH is transmitted will be described. That is, when simultaneous transmission of PUCCH and PUSCH is set in P cell or pS cell, when PUCCH transmission and PUSCH transmission occur in the same subframe, a method of inserting PUCCH uplink control information into PUSCH and transmitting is described. In the above case, when PUCCH and PUSCH are simultaneously transmitted to the UE, the PUCCH and the PUSCH can be simultaneously transmitted and the PUCCH and PUSCH are simultaneously transmitted as the upper signal.

First, if the cell group 1 includes more than one cell, if the P-cell transmits the PUCCH, the uplink control information insertion is determined based on the PUSCH transmission in the cell group 1 and the type of the UL control information. For example, when the PUSCH transmission occurs in the P-cell, if the uplink control information of the uplink control channel transmitted in the P-th cell is periodic channel information and HARQ-ACK feedback, the HARQ- Is transmitted in the PUCCH of the P cell, and the periodic channel information is inserted in the PUSCH of the P cell and transmitted. As another example, if a PUSCH transmission occurs in an S-cell of a cell group 1 other than a P-cell, if the uplink control information of the PUCCH transmitted in the P-cell is periodic channel information and HARQ-ACK feedback, Of the information, HARQ-ACK feedback is transmitted in the PUCCH of the P-th cell, and the periodic channel information is inserted in the PUSCH of the S-cell having the smallest S-cell index among the S-cells of the cell group 1 transmitting the PUSCH. As another example, if a PUSCH transmission occurs in the cell due to a request for transmission of aperiodic channel information for a cell belonging to cell group 1, the uplink control information of the PUCCH transmitted in the P-cell is transmitted as non- The HARQ-ACK feedback / scheduling request information of the uplink control information is transmitted in the PUCCH of the P-cell, and the aperiodic channel information is transmitted to the non-periodic channel of the cell Inserted into the PUSCH due to the information request and transmitted. In general, since the power of the PUCCH is higher than the PUSCH, the feedback of the HARQ-ACK, which directly affects the throughput of the UE, is reliably transmitted using the PUCCH and the channel information that does not significantly affect the throughput of the UE is limited And inserts it in the PUSCH to save resources of the PUCCH. The above insertion and transmission operations are applied in the same manner even when the cell group 2 includes one or more cells, and when the pS cell transmits the PUCCH, insertion of the uplink control information is determined based on the PUSCH transmission in the cell group 2 do.

Next, when the cell group 1 includes only one cell (i.e., P cell), if the P cell transmits the PUCCH and the PUSCH transmission occurs in the cell group 1, the uplink control information insertion . For example, when a PUSCH transmission occurs in a cell belonging to cell group 1 in the same subframe, HARQ-ACK feedback / scheduling request information of uplink control information of a PUCCH transmitted in the P cell is transmitted in a PUCCH, / Non-periodic channel information is inserted into the PUSCH and transmitted. The above insertion and transmission operations are applied in the same manner even when the cell group 2 includes only one cell (i.e., pS cell), and if the pS cell transmits a PUCCH, the uplink control Information insertion is determined.

4, when the uplink control channel and the uplink data channel are simultaneously transmitted to the UE and the uplink control channel overlaps with the uplink data channel in the cell in which the uplink control channel is transmitted, The operation of the base station and the terminal will be described.

4A is a flow chart illustrating the operation of the base station. First, in step 401, the base station sets up a simultaneous PUCCH and PUSCH transmission to the UE as an upper signal in the PUCCH transmission cell of the cell group (P cell in the case of the cell group 1 and pS cell in the case of the cell group 2). The concurrent transmission of the PUCCH and the PUSCH corresponds to the PUCCH and PUSCH simultaneous transmission, and the simultaneous transmission of the PUCCH and the PUSCH are set as the upper signal. If it is determined in step 402 that the PUCCH reception and the PUSCH reception conflict in the subframe n, that is, the subframe in which the PUCCH is to be received from the terminal and the subframe in which the PUSCH is to be received from the terminal coincide with each other, in step 403, (I.e., cell group 1 if the PUCCH transmission cell is a P-cell and cell group 2 if the PUCCH transmission cell is a pSCH) includes one or more cells or only one cell. If the cell group that transmits the PUCCH includes one or more cells in step 403, the uplink control information is transmitted to the PUSCH based on the status of the PUSCH transmission in the cell group proposed in the present invention and the type of the uplink control information, The uplink control information is extracted from the received PUSCH. If the cell group transmitting the PUCCH includes only one cell in step 403, if the PUSCH transmission in the cell group proposed in the present invention occurs in step 405, the uplink control information is inserted into the PUSCH according to the type of the uplink control information The uplink control information is extracted from the received PUSCH.

4B is a flowchart showing the operation of the terminal. First, in step 411, a UE is set to transmit a PUCCH and a PUSCH as upper signals in a PUCCH transmission cell of a cell group (P cell in case of cell group 1 and pS cell in case of cell group 2). When simultaneous transmission of the PUCCH and PUSCH is set in the UE, it is possible to simultaneously transmit PUCCH and PUSCH, and corresponds to a UE in which simultaneous transmission of PUCCH and PUSCH is set as a higher signal. If it is determined in step 412 that the PUCCH transmission and the PUSCH transmission conflict in the subframe n, that is, the subframe in which the UE transmits the PUCCH matches the subframe in which the UE transmits the PUSCH, the UE determines in step 413 that the cell group The cell group 1 if the PUCCH transmission cell is a P cell, and the cell group 2 if the PUCCH transmission cell is a pS cell) includes one or more cells or only one cell. If the cell group that transmits the PUCCH includes one or more cells in step 413, the uplink control information is transmitted based on the status of the PUSCH transmission in the cell group proposed in the present invention and the type of the UL control information in step 414 PUSCH, the uplink control information is inserted into the PUSCH and transmitted. If the PUSCH transmission in the cell group proposed in the present invention occurs in step 415, if the cell group transmitting the PUCCH includes only one cell in step 413, unconditional uplink control information is transmitted to the PUSCH according to the type of the uplink control information And inserts the uplink control information into the PUSCH and transmits the same.

Thirdly, the insertion and transmission operations in the cell group 1 in the case where PUCCH and PUSCH simultaneous transmission are set in the mobile station only in the P-cell will be described. That is, when simultaneous transmission of PUCCH and PUSCH is set in P cell, a method of inserting PUCCH uplink control information into a PUSCH and transmitting the same when PUCCH transmission and PUSCH transmission occur in the same subframe will be described. In the above case, when PUCCH and PUSCH simultaneous transmission are set in the P-cell only, the PUCCH and PUSCH can be simultaneously transmitted only in the P-cell, and the PUCCH and PUSCH can be simultaneously transmitted. Cell is set as the upper signal only.

First, if the cell group 1 includes more than one cell, if the P-cell transmits the PUCCH, the uplink control information insertion is determined based on the PUSCH transmission in the cell group 1 and the type of the UL control information. For example, if PUSCH transmission occurs in a P-cell, if uplink control information of an uplink control channel transmitted in the P-cell is periodic channel information and HARQ-ACK feedback, HARQ-ACK feedback Is transmitted in the PUCCH of the P cell, and the periodic channel information is inserted in the PUSCH of the P cell and transmitted. As another example, if a PUSCH transmission occurs in an S cell of a cell group 1 other than a P cell, if the uplink control information of the PUCCH transmitted in the P cell is periodic channel information and HARQ-ACK feedback, Of the control information, HARQ-ACK feedback is transmitted in the PUCCH of the P cell, and the periodic channel information is inserted in the PUSCH of the S cell having the smallest S cell index among the S cells of the cell group 1 transmitting the PUSCH. As another example, if a PUSCH transmission occurs in the cell due to a request for transmission of aperiodic channel information for a cell belonging to cell group 1, the uplink control information of the PUCCH transmitted in the P-cell is transmitted as non- The HARQ-ACK feedback / scheduling request information of the uplink control information is transmitted in the PUCCH of the P-cell and the aperiodic channel information is inserted in the PUSCH due to the non-periodic channel information request of the cell And transmitted.

Next, when the cell group 1 includes only one cell (i.e., P cell), if the P cell transmits PUCCH, if the PUSCH transmission occurs in the cell group 1, the uplink control information insertion is performed according to the type of the uplink control information . For example, when a PUSCH transmission occurs in a cell belonging to cell group 1 in the same subframe, HARQ-ACK feedback / scheduling request information of the uplink control information of the PUCCH transmitted in the P-cell is transmitted in the PUCCH, The periodic channel information is inserted in the PUSCH and transmitted.

5, simultaneous transmission of an uplink control channel and an uplink data channel simultaneously in a P cell can be set to the UE, and when the setting is indicated as an upper signal and the uplink control channel overlaps with the uplink data channel in the cell group 1 , And the operation of the base station and the terminal for inserting control information into the uplink data channel in the cell group 1 will be described.

5A is a flowchart showing the operation of the base station. First, in step 501, the base station sets up a simultaneous PUCCH and PUSCH transmission as an upper signal for a P cell, which is a PUCCH transmission cell of the cell group 1, to the UE. The concurrent transmission of the PUCCH and the PUSCH corresponds to the PUCCH and PUSCH simultaneous transmission, and the simultaneous transmission of the PUCCH and the PUSCH are set as the upper signal. If it is determined in step 502 that the PUCCH reception and the PUSCH reception conflict in the subframe n, that is, the subframe in which the PUCCH is to be received from the terminal and the subframe in which the PUSCH is to be received from the terminal coincide with each other, then in step 503, It is judged whether the cell includes only one cell or not. If the cell group 1 includes one or more cells in step 503, the uplink control information is transmitted to the PUSCH based on the situation of the PUSCH transmission in the cell group 1 proposed by the present invention and the type of the uplink control information, The uplink control information is extracted from the received PUSCH. If the cell group 1 includes only one cell in step 503, if the PUSCH transmission in the cell group 1 proposed by the present invention occurs in step 505, the method of inserting the uplink control information into the PUSCH according to the type of the uplink control information And extracts the uplink control information from the received PUSCH.

Next, FIG. 5B is a flowchart showing the operation of the terminal. First, in step 511, the UE sets a simultaneous PUCCH and PUSCH transmission as an upper signal in a P-cell, which is a PUCCH transmission cell of the cell group 1. When simultaneous transmission of the PUCCH and PUSCH is set in the UE, it is possible to simultaneously transmit PUCCH and PUSCH, and corresponds to a UE in which simultaneous transmission of PUCCH and PUSCH is set as a higher signal. If it is determined in step 512 that the PUCCH transmission and the PUSCH transmission conflict in the subframe n, that is, the subframe in which the UE transmits the PUCCH matches the subframe in which the UE transmits the PUSCH, the UE determines in step 513 that the cell group 1 includes one or more cells Or only one cell is included. If the cell group 1 includes more than one cell in step 513, the uplink control information is transmitted to the PUSCH based on the situation of the PUSCH transmission in the cell group 1 proposed in the present invention and the type of the uplink control information, And inserts the uplink control information into the PUSCH and transmits the same. If the cell group 1 includes only one cell in step 513, if the PUSCH transmission in the cell group 1 proposed by the present invention occurs in step 515, the method of inserting the uplink control information into the PUSCH according to the type of the uplink control information The uplink control information is inserted into the PUSCH and transmitted.

Next, referring to FIG. 6, when the PUCCH transmission and the PUSCH transmission based on the multiple cell groups of FIGS. 2B, 2C and 2D occur in the same subframe, the uplink control information of the PUCCH is inserted into the PUSCH And then transmits the data to the transmitter. That is, when a plurality of cell groups are set in the UE for carrier integration, even if the PUSCH is transmitted in the cells of the cell group 1 and the PUSCH is not transmitted in the cells of the cell group 2 but only the PUCCH is transmitted in the pS cell, the control information of the PUCCH of the pS cell may be inserted into the PUSCH transmitted in the cells of the cell group 1 and transmitted. Even in this case, since the PUCCH transmission and the PUSCH transmission can be performed for each cell group, the power scaling order can be interlocked with the uplink control information type of PUCCH transmission and PUSCH transmission when UE uplink power control is performed. have. For example, when HARQ-ACK feedback is inserted in the PUSCH of the cell group 1 and channel information is transmitted to the PUCCH of the cell group 2, when the power of the UE is limited, the PUCCH transmission power of the cell group 2 is scaled . As another example, when channel information is inserted in the PUSCH of the cell group 1 and HARQ-ACK feedback is transmitted to the PUCCH of the cell group 2, when the power of the UE is limited, the transmission power of the PUSCH of the cell group 1 is scaled .

The operation of inserting and transmitting uplink control information in the cell group 2 in the case where simultaneous transmission of PUCCH and PUSCH is set in the UE will be described. That is, when simultaneous transmission of PUCCH and PUSCH is set in P cell, when PUCCH transmission in pS cell and PUSCH transmission in cell group occur in the same subframe, PUCCH uplink control information is inserted into PUSCH for transmission Explain the method. In the above case, when simultaneous transmission of PUCCH and PUSCH is set in the P-cell, PUCCH and PUSCH can be simultaneously transmitted only in P-cell, and simultaneously PUCCH and PUSCH can be simultaneously transmitted. Only the terminal set as the upper signal.

When a pS cell transmits a PUCCH in a cell group 2, since a PUSCH can not be transmitted originally in a pS cell, a PUSCH transmission occurs in all cells regardless of a cell group, and an uplink control Information insertion is determined. Therefore, this case does not distinguish whether cell group 2 includes one or more cells or only one cell. For example, if PUSCH transmission occurs in P cell of cell group 1, if uplink control information of the uplink control channel transmitted in the pS cell is periodic channel information and HARQ-ACK feedback, HARQ- ACK feedback is transmitted in the PUCCH of the pS cell, and periodic channel information is inserted in the PUSCH of the P cell of the cell group 1 and transmitted. As another example, when a PUSCH transmission occurs in an S-cell of a cell group 1 and a cell group 2 other than a P-cell, the uplink control information of the PUCCH transmitted in the pS cell is periodic channel information and HARQ- , The HARQ-ACK feedback of the uplink control information is transmitted in the PUCCH of the pS cell, and the periodic channel information is transmitted to the S-cell having the S-cell index having the smallest S-cell among the S-cells of the cell group 1 and the cell group 2 transmitting the PUSCH And then transmitted. As another example, if a PUSCH transmission occurs in the cell due to a request for transmission of aperiodic channel information for a cell belonging to cell group 1 and cell group 2, the uplink control information of the PUCCH transmitted in the pS cell becomes non- The HARQ-ACK feedback / scheduling request information of the uplink control information is transmitted in the PUCCH of the pS cell, and the aperiodic channel information is information of the non-periodic channel information of the cell Inserted into the PUSCH due to the request and transmitted.

The above embodiment can be applied regardless of whether PUCCH and PUSCH simultaneous transmission are set in P cell or pS cell from the viewpoint of transmitting uplink control information through one PUSCH regardless of cell group . If the PUCCH and the PUSCH are simultaneously transmitted in the P-cell and the pS-cell and the PUCCH including the HARQ-ACK feedback is transmitted in the P-cell and the pS-cell respectively and the periodic or aperiodic channel information is transmitted through the PUSCH, And one PUSCH may be simultaneously transmitted. Therefore, in this case, power scaling when performing uplink power control of the terminal can be performed as follows. The PUSCH transmit power is scaled first and the PUCCH with a small number of HARQ-ACK feedback currently being actually transmitted during the two PUCCH transmissions can be scaled first. For example, if the HARQ-ACK feedback transmitted for the actual data transmission in the P cell is 6 bits and the HARQ-ACK feedback transmitted for the actual data transmission in the pS cell is 4 bits, the PUCCH transmitted in the pS cell is scaled first. As another example, a PUCCH with a small number of cells included in a cell group can be scaled first. For example, if the number of cells included in cell group 1 is 2 including P cell, and the number of cells included in cell group 2 is 3 including pS cell, the PUCCH transmitted from P cell is scaled first. As another example, the PUCCH with a small number of HARQ-ACK feedback considering the number of cells and the transmission mode included in the cell group can be scaled first. For example, if the transmission mode of the P cell in each transmission mode of the P cell and the S cell 1 included in the cell group 1 is a transmission mode in which two codewords are transmitted, and the transmission mode of the S cell 1 is two codewords A total of four HARQ-ACK feedback numbers are expected as a transmission mode for transmitting pS cells in the cell group 2. In a transmission mode of each of the pS cell, the S cell 3 and the S cell 4 included in the cell group 2, When the transmission mode of the S-cell 3 is a transmission mode for transmitting one codeword and the transmission mode of the S-cell 4 is a transmission mode for transmitting one codeword, a total of three HARQ-ACK feedback numbers It is expected. Therefore, in this case, the PUCCH of the pS cell can be scaled first. As another example, considering that it is important for the system operation that HARQ-ACK feedback for the control information is transmitted in time, control information at the upper level can be transmitted in the P-cell. Therefore, the PUCCH of the p- Carling may be considered.

6, simultaneous transmission of an uplink control channel and an uplink data channel simultaneously in a P-cell can be set to the UE, and when the setting is indicated as an upper signal and the uplink control channel overlaps with the uplink data channel regardless of the cell group The operation of the base station and the terminal for inserting control information into the uplink data channel will be described.

First, in step 601, the base station sets up a simultaneous PUCCH and PUSCH transmission as an upper signal for a P cell that is a PUCCH transmission cell of the cell group 1. The concurrent transmission of the PUCCH and the PUSCH corresponds to the PUCCH and PUSCH simultaneous transmission, and the simultaneous transmission of the PUCCH and the PUSCH are set as the upper signal. In step 602, the PUCCH reception of the pS cell and the reception of the PUSCH in a certain cell regardless of the cell group collide in the subframe n, that is, the subframe in which the PUCCH is to be received from the terminal and the subframe A method of inserting the uplink control information in the PUCCH of the pS cell into the PUSCH based on the situation of the PUSCH transmission regardless of the cell group proposed in the present invention and the type of the uplink control information in step 603, Information is extracted from the received PUSCH.

6B is a flowchart showing a terminal operation. First, in step 611, the UE sets a simultaneous PUCCH and PUSCH transmission as an upper signal in a P-cell, which is a PUCCH transmission cell of the cell group 1. When simultaneous transmission of the PUCCH and PUSCH is set in the UE, it is possible to simultaneously transmit PUCCH and PUSCH, and corresponds to a UE in which simultaneous transmission of PUCCH and PUSCH is set as a higher signal. In step 612, regardless of the PUCCH transmission of the pS cell and the PUSCH transmission in any cell regardless of the cell group, a collision occurs in the subframe n, that is, when the subframe in which the UE must transmit the PUCCH matches the subframe in which the UE transmits the PUSCH In step 613, uplink control information is inserted into the PUSCH based on a situation in which the PUSCH transmission occurs regardless of the cell group proposed in the present invention and the type of uplink control information in the pUCCH of the pS cell, PUSCH for transmission.
