Abstract

Disclosed in the present application is a hybrid automatic repeat request feedback method, which comprises the steps that: an HARQ-ACK codebook includes HARQ-ACK information of M PDSCHs, the M PDSCHs are all scheduled by first-type PDCCHs, and the first-type PDCCHs are used for activating an SPS configuration; the order of the HARQ-ACK information of the M PDSCHs in the HARQ-ACK codebook is arranged according to at least one parameter value among cell indexes, BWP indexes, SPS configuration indexes and PDSCH transmission moments of the M PDSCHs. The embodiments of the present application also provide a hybrid automatic repeat request feedback method with the participation of second-type PDCCHs for releasing SPS and dynamically configured third-type PDCCHs. The present application also provides a terminal device and a network device to which the method is applied. The present application solves the problem of how to generate an HARQ-ACK codebook when there are multiple PDSCHs in an SPS configuration condition.
