Abstract

Embodiments of the present application provide an HARQ feedback method, a terminal, a base station and a storage medium. The method includes: adding, in an HARQ-ACK codebook which is determined according to a time offset K1 set and is transmitted in a time unit, A bits HARQ-ACK feedback corresponding to SPS PDSCHs to obtain an HARQ-ACK codebook to be transmitted; and transmitting the HARQ-ACK codebook. In the embodiments of the present application, in case that the SPS PDSCH is deferred, or is determined to feed back HARQ-ACK in a time unit based on a K1 value that does not belong to the K1 set, the HARQ-ACK of the SPS PDSCH needs to be added in the HARQ-ACK codebook determined based on the K1 set and corresponding to the time unit, so that correct HARQ-ACK transmission is ensured, and the HARQ-ACK of the SPS PDSCH is prevented from being discarded.
