1. A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver configured to receive, from a base station, via a system information signaling or a dedicated signaling, information indicating a channel access procedure to apply for operation with shared spectrum channel access including period information; and
a processor operably coupled to the transceiver, the processor configured to identify a period for the channel access procedure, a channel occupancy time, and an idle duration based on the period information included in the information indicating the channel access procedure to apply for operation with shared spectrum channel access,
wherein the transceiver is further configured to:
perform a first downlink (DL) reception within the channel occupancy time, and
perform a first uplink (UL) transmission on a channel after the first DL reception within the channel occupancy time without sensing the channel in case a gap between the first DL reception and the first UL transmission is at most a certain duration, and
wherein there is no transmission by the UE in the idle duration before a start of a next period for the channel access procedure.
