Abstract
The embodiments of the present application relate to a method for performing hybrid automatic repeat request feedback, and a terminal, for solving the problem existing in the prior art that there is no clear solution regarding how to perform feedback on HARQ-ACK of an SPS PDSCH. In the embodiments of the present application, the terminal adds or removes HARQ-ACK of an SPS PDSCH in an HARQ-ACK codebook transmitted over a PUCCH or a PUSCH, and transmits a processed HARQ-ACK codebook. Since the terminal can add or remove the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook transmitted over the PUCCH or the PUSCH, a solution to perform feedback on the HARQ-ACK of the SPS PDSCH is given, improving system performance.
