1. A hybrid automatic repeat request (HARQ) feedback method for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) with shorter periodicity, comprising:
adding, in an HARQ-acknowledgement (ACK) codebook which is determined according to a time offset K1 set and is transmitted in a first time unit, A bits HARQ-ACK feedback corresponding to SPS PDSCHs to obtain another HARQ-ACK codebook to be transmitted, wherein the A satisfies preset conditions that the A is a number of SPS PDSCHs in time units that do not belong to a time unit set determined based on the K1 set and corresponding to the first time unit, and the SPS PDSCH is an SPS PDSCH that is deferred to feed back HARQ-ACK in the first time unit or is determined to feed back HARQ-ACK in the first time unit based on a K1 value that does not belong to the K1 set; and
transmitting the another HARQ-ACK codebook to be transmitted.
