Abstract: A Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) codebook construction method and transmission method, and a device, are provided. The HARQ-ACK codebook construction method includes: obtaining a time domain feedback record set, where each time domain feedback record in the time domain feedback record set includes a time domain resource assignment record and an equivalent feedback time offset corresponding to the time domain resource assignment record, and the equivalent feedback time offset is a feedback time offset value actually applied when a HARQ-ACK for the time domain resource assignment record corresponding to the equivalent feedback time offset is fed back in an uplink slot; dividing the time domain feedback record set into subsets based on equivalent feedback time offset(s), where each equivalent feedback time offset corresponds to one subset; and constructing a HARQ-ACK codebook based on the subsets obtained through division, to perform feedback in the uplink slot.
