Abstract: The provided is a method for transmtting HARQ-ACK in a LTE system, which is applicable to a situation that an upink subframe is occupied in an FDD or TDD sytem. The method is implemented as follows. A UE receives information from an eNB, and determines the assignment of uplink subframes in a cell. The UE determines the transmission of HARQ-ACK according to the assignment of uplink subframes in the cell. By the provided method, the transmission of HARQ-ACK of PDSCH is less influenced when an uplink subframe in the FDD or TDD system is occupied.
