1. A user equipment (UE), comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive, from a base station, one or multiple downlink transmissions within a channel occupancy time initiated by the base station;
determine a downlink association set for a hybrid automatic repeat request (HARQ) acknowledgement (ACK) codebook, wherein the downlink association set comprises a set of slots, excludes one or more downlink slots from the downlink association set based on a predefined rule, and generates the HARQ ACK codebook corresponding to the downlink association set, wherein the HARQ ACK codebook comprises HARQ ACK information bits for the one or multiple downlink transmissions; and
transmit the HARQ ACK codebook to the base station, wherein the predefined rule comprises excluding the one or more downlink slots from the downlink associate set for downlink transmissions that cannot be acknowledged or non-acknowledged in a slot where the HARQ ACK codebook is to be transmitted.
