Abstract: The present disclosure provides a method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information. In the method provided by the present disclosure, an evolved Node B (eNB) transmits Downlink Assignment (DL-GRANT) within a time-frequency bundling window, which corresponds to an uplink subframe feeding back HARQ-ACK. A UE receives DL-GRANT scheduling downlink HARQ transmission in the time-frequency bundling window corresponding to respective uplink subframe for feeding back HARQ-ACK in turn, obtains a DL DAI in the DL-GRANT, and determines a mapping value of each DL DAI; then, maps HARQ-ACK bits of the time-frequency bundling window corresponding to respective uplink subframe for feeding back the HARQ-ACK to corresponding bits of a feedback bit sequence according to the mapping value of the DL DAI; and transmits the HARQ-ACK on an available uplink carrier. The present disclosure also provides a method for feeding back HARQ-ACK information. The UE transmits HARQ-ACK on an indicated carrier according to indication information of a base station. According to the method and apparatus provided by the present disclosure, efficiency for feeding back the HARQ-ACK can be increased and downlink peak rate of the UE can be ensured.
