The present invention provides a method for determining a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook, a terminal and a network device. The method comprises: when an HARQ-ACK is transmitted in a first timeslot, determining an HARQ-ACK codebook in the first timeslot according to a target offset set. The HARQ-ACK is an HARQ-ACK of a PDSCH or SPS PDSCH release transmitted in a second timeslot, the target offset set W=K1+TA_offset, K1 is a set of timeslot timing values of intervals between a transmission timeslot of the PDSCH or SPS PDSCH release and a transmission timeslot of the corresponding HARQ-ACK, TA_offset is a signaling configuration or a value related to TA obtained in a predetermined mode, n_U=n+k+TA_offset, k is a value in the set K1, n_U is the serial number of the first timeslot, and n is the serial number of the second timeslot.
