HARQ method and apparatus for communication system

摘要

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.

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.
