Abstract: The present disclosure discloses a method for performing a hybrid automatic repeat request (HARQ) feedback, method comprises: receiving data units; performing group bundling on the data units, wherein at least one data unit is bundled into more than one groups; determining, according to decoding results of the data units in each of the groups, ACK/NACK information of corresponding groups; feeding back ACK/NACK information of different bundled groups to the transmitter. Compared with the prior art, according to the present disclosure, a receiver performs grouping on data units in a way of overlapping bundling, group is used as a unit for feedback of ACK/NACK information, thus feedback overhead of HARQ feedback is reduced, data amount of HARQ-transmitter error retransmission is significantly reduced and efficiency of error retransmission is improved. In addition, the present disclosure further provides an HARQ retransmission method.

Abstract: An apparatus and method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information are provided. The apparatus and method include user equipment (UE) that first receives a downlink grant (DL-GRANT) which schedules downlink HARQ transmission in a time-frequency bundling window corresponding to an uplink subframe used for feeding back HARQ-ACK, obtains a DL downlink assignment index (DL DAI) in the DL-GRANT, and determines a mapping value of each DL DAI. Then, according to the mapping value of the corresponding DL DAI, the HARQ-ACK bit of each HARQ feedback unit is mapped to a corresponding bit of a feedback bit sequence. According to the method and apparatus provided by the present disclosure, useless HARQ-ACK bits may be effectively removed, and efficiency for feeding back HARQ-ACK may be increased. As such, a downlink peak rate of a UE is ensured.
