HARQ-ACK码本，信息的确定方法及装置

摘要

Provided in the present application are an HARQ-ACK codebook, and an information determination method and apparatus. An HARQ-ACK codebook determination method comprises: providing multiple physical downlink shared channel (PDSCH) candidate resources having overlapping time domains in a downlink slot into one candidate resource group, and determining HARQ-ACK information corresponding to the candidate resource group; and determining a corresponding downlink subslot for the HARQ-ACK information according to a preset rule, and determining a semi-static HARQ-ACK codebook. By means of the present application, the problem that a semi-static HARQ-ACK codebook cannot be determined when a PDSCH candidate resource is cross-subslot can be solved, thereby yielding the effect of meeting the HARQ-ACK requirement in the case that the PDSCH candidate resource is cross-subslot.
