Claim 5:
6. A method for performing hybrid automatic repeat request feedback, comprising:
determining, by a network side device, that hybrid automatic repeat request acknowledge (HARQ-ACK) of a semi-persistent scheduling physical downlink shared channel (SPS PDSCH) is added by a terminal in an HARQ-ACK codebook transmitted on a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH); and
receiving, by the network side device, a processed HARQ-ACK codebook sent by the terminal according to a determined result;
wherein the determining, by the network side device, that the HARQ-ACK of the SPS PDSCH is added by the terminal in the HARQ-ACK codebook transmitted on the PUCCH or the PUSCH comprises a scheme 1 or 2:
the scheme 1: determining, by the network side device, according to the HARQ-ACK timing of the SPS PDSCH, that the HARQ-ACK of the SPS PDSCH is added by the terminal in the HARQ-ACK codebook; the determining, by the network side device, according to the HARQ-ACK timing of the SPS PDSCH, that the HARQ-ACK of the SPS PDSCH is added by the terminal in the HARQ-ACK codebook comprises: determining, by the network side device, that the HARQ-ACK of the SPS PDSCH is added by the terminal in the HARQ-ACK codebook, in the condition that the network side device determines, 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 determining, by the network side device, that the HARQ-ACK of the SPS PDSCH is added by the terminal in the HARQ-ACK codebook, in the condition that the network side device determines, 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:
determining, by the network side device, that the HARQ-ACK of the SPS PDSCH is added by the terminal 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
determining, by the network side device, that the HARQ-ACK of the SPS PDSCH is added by the terminal 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, by the network side device, 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 by the terminal in the HARQ-ACK codebook transmitted on the PUCCH or the PUSCH, wherein the downlink transmission is a PDSCH or a PDCCH indicating downlink SPS release;
the determining, by the network side device, according to whether 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, whether the HARQ-ACK of the SPS PDSCH is added by the terminal in the HARQ-ACK codebook transmitted on the PUCCH or the PUSCH comprises:
determining, by the network side device, 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, that the HARQ-ACK of the SPS PDSCH is added by the terminal in the HARQ-ACK codebook.
