Patent ID: 10880051

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.
