1. A user equipment (UE) for use in a wireless communication system, the UE comprising:
a communication module; and
a processor configured to control the communication module,
wherein the processor is configured to
receive configuration information related to a base station (BS) fixed frame period (FFP) including a first idle duration, transmission of an uplink channel;
receive configuration information related to a UE FFP including a second idle duration, and
perform an uplink (UL) transmission based on whether the UL transmission is associated with either BS-initiated channel occupancy (CO) or UE-initiated CO,
wherein, when the UL transmission is scheduled by a configured grant (CG),
if a previously-initiated UE-initiated CO is in the UE FFP, the UL transmission is determined as being associated with the previously-initiated UE-initiated CO, and
if no previously-initiated UE-initiated CO is in the UE FFP, whether the UL transmission is determined as being associated with the BS-initiated CO is based on a downlink (DL) channel detection result of the UE.
