Abstract
Methods and apparatuses are provided for data transmission of a User Equipment (UE) in a communication system supporting HARQ. A Physical Downlink Control Channel (PDCCH) corresponding to a second cell is received in a first cell. An Uplink/Downlink (UL/DL) configuration of the first cell is identified as an Uplink (UL) reference UL/DL configuration if the UE is configured with at least two cells including the first cell and the second cell a PDCCH corresponding to the second cell is monitored on the first cell and a pair of the UL/DL configuration of the first cell and a UL/DL configuration of the second cell is a predetermined set. A Physical Uplink Shared Channel (PUSCH) transmission is adjusted based on the identified UL reference UL/DL configuration.

Claim
1. A method for data transmission in a communication system, the method comprising:
receiving, by a terminal, a physical downlink control channel (PDCCH) corresponding to a second cell on a first cell; and
transmitting, by the terminal, a physical uplink shared channel (PUSCH) corresponding to the PDCCH based on a time division duplex (TDD) uplink/downlink (UL/DL) configuration of the first cell,
wherein the TDD UL/DL configuration of the first cell and a TDD UL/DL configuration of the second cell are different, the TDD UL/DL configuration of the first cell is a first TDD UL/DL configuration and the TDD UL/DL configuration of the second cell is a second TDD UL/DL configuration.
2. The method of claim 1, further comprising:
receiving, by the terminal, a response corresponding to the PUSCH on a physical hybrid automatic repeat request indicator channel (PHICH) in a subframe identified based on the TDD UL/DL configuration of the first cell.
3. The method of claim 1, wherein any subframe of the first TDD UL/DL configuration corresponding to an uplink subframe of the second TDD UL/DL configuration is an UL sub-frame.
4. The method of claim 1, wherein control information corresponding to the PDCCH comprises one carrier indicator corresponding to the second cell.
5. The method of claim 1, wherein the first TDD UL/DL configuration is TDD UL/DL configuration 1 and the second TDD UL/DL configuration is TDD UL/DL configuration 2.
6. A method of data reception in a communication system, the method comprising:
transmitting, by a base station, a physical downlink control channel (PDCCH) corresponding to a second cell on a first cell;
receiving, by the base station, a physical uplink shared channel (PUSCH) based on a time division duplex (TDD) uplink/downlink (UL/DL) configuration of the first cell,
wherein the TDD UL/DL configuration of the first cell and a TDD UL/DL configuration of the second cell are different, the TDD UL/DL configuration of the first cell is a first TDD UL/DL configuration and the TDD UL/DL configuration of the second cell is a second TDD UL/DL configuration.
7. The method of claim 6, further comprising:
transmitting, by the base station, a response corresponding to the PUSCH on a physical hybrid automatic repeat request indicator channel (PHICH) in a subframe identified based on the TDD UL/DL configuration of the first cell.
8. The method of claim 6, wherein any subframe of the first TDD UL/DL configuration corresponding to an uplink subframe of the second TDD UL/DL configuration is an UL sub-frame.
9. The method of claim 6, wherein control information corresponding to the PDCCH comprises one carrier indicator corresponding to the second cell.
10. The method of claim 6, wherein the first TDD UL/DL configuration is TDD UL/DL configuration 1 and the second TDD UL/DL configuration is TDD UL/DL configuration 2.
11. An information transmission apparatus of a terminal in a communication system, the apparatus comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to control:

transmitting a physical uplink shared channel (PUSCH) corresponding to the PDCCH based on a time division duplex (TDD) uplink/downlink (UL/DL) configuration of the first cell,
wherein the TDD UL/DL configuration of the first cell and a TDD UL/DL configuration of the second cell are different, the TDD UL/DL configuration of the first cell is a first TDD UL/DL configuration and the TDD UL/DL configuration of the second cell is a second TDD UL/DL configuration.
12. The apparatus of claim 11, wherein the controller is further configured to control receiving a response corresponding to the PUSCH on a physical hybrid automatic repeat request indicator channel (PHICH) in a subframe identified based on the TDD UL/DL configuration of the first cell.
13. The apparatus of claim 11, wherein any subframe of the first TDD UL/DL configuration corresponding to an uplink subframe of the second TDD UL/DL configuration is an uplink subframe.
14. The apparatus of claim 11, wherein control information corresponding to the PDCCH comprises at least one carrier indicator corresponding to the second cell.
15. The apparatus of claim 11, wherein the first TDD UL/DL configuration is TDD UL/DL configuration 1 and the second TDD UL/DL configuration is TDD UL/DL configuration 2.
16. An information reception apparatus of a base station in a communication system, the apparatus comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to control:
transmitting a physical downlink control channel (PDCCH) corresponding to a second cell on a first cell; and
receiving a physical uplink shared channel (PUSCH) corresponding to the PDCCH based on a time division duplex (TDD) uplink/downlink (UL/DL) configuration of the first cell,
wherein the TDD UL/DL configuration of the first cell and a TDD UL/DL configuration of the second cell are different, the TDD UL/DL configuration of the first cell is a first TDD UL/DL configuration, and the TDD UL/DL configuration of the second cell is a second TDD UL/DL configuration.
17. The apparatus of claim 16, wherein the controller is configured to control:
transmitting a response corresponding to the PUSCH on a physical hybrid automatic repeat request indicator channel (PHICH) in a subframe identified based on the TDD UL/DL configuration of the first cell.
