Abstract:
A method and device for retransmitting data is provided. A receiving end receives a data unit, and checks whether a Negative Acknowledgement NACK->Acknowledgement, ACK, error occurs. If the NACK->ACK error occurs, the receiving end transmits an Automatic Repeat Request ARQ request message to a transmitting end, for requesting the transmitting end to perform an ARQ retransmission. Therefore, by adopting the technical solutions of the embodiment of the invention, Hybrid Automatic Repeat Request HARQ NACK->ACK errors are avoided from being missed, the complexity of ARQ operation is lowered, and the ARQ retransmission feedback time is reduced.
