Claim 10:
11. A terminal for performing hybrid automatic repeat request feedback, comprising: a processor and a memory;
wherein the processor is configured to read a program in the memory to perform the following process:
determining a hybrid automatic repeat request acknowledge (HARQ-ACK) codebook transmitted on a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH);
adding HARQ-ACK of a semi-persistent scheduling physical downlink shared channel (SPS PDSCH) in the HARQ-ACK codebook;
wherein the adding the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook comprises a scheme 1 or 2:
the scheme 1: adding the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook according to HARQ-ACK timing of the SPS PDSCH; wherein the adding the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook according to the HARQ-ACK timing of the SPS PDSCH comprises: adding, the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook, in the condition that it is determined, according to the HARQ-ACK timing of the SPS PDSCH, that the HARQ-ACK of the SPS PDSCH and the HARQ-ACK codebook are transmitted at the same time;
the adding, the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook, in the condition that it is determined, according to the HARQ-ACK timing of the SPS PDSCH, that the HARQ-ACK of the SPS PDSCH and the HARQ-ACK codebook are transmitted at the same time comprises:
adding the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook, in the condition that the HARQ-ACK codebook is transmitted at time n and time n-k is time at which the terminal receives the SPS PDSCH; wherein k is the HARQ-ACK timing of the SPS PDSCH; or
adding the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook transmitted at transmission time n+k, in the condition that transmission time of the SPS PDSCH is n; wherein k is the HARQ-ACK timing of the SPS PDSCH,
the scheme 2: determining, according to whether a set of downlink transmission corresponding to time at which the HARQ-ACK codebook is transmitted comprises a transmission occasion of the SPS PDSCH, whether the HARQ-ACK of the SPS PDSCH is added in the HARQ-ACK codebook, wherein the downlink transmission is a PDSCH or a PDCCH indicating downlink SPS release;
the determining, according to whether a set of downlink transmission corresponding to time at which the HARQ-ACK codebook is transmitted comprises a transmission occasion of the SPS PDSCH, whether the HARQ-ACK of the SPS PDSCH is added in the HARQ-ACK codebook comprises:
adding, in the condition that the set of downlink transmission corresponding to the time at which the HARQ-ACK codebook is transmitted comprises the transmission occasion of the SPS PDSCH, the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook.
