Claim 0:
1. A method of performing a channel access procedure on a shared spectrum by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, in a first period for a base station (BS)-initiated channel occupancy, downlink control information (DCI) for a scheduled uplink (UL) transmission, and
performing a channel access procedure for the scheduled UL transmission associated with a UE-initiated channel occupancy,
wherein i) the scheduled UL transmission is entirely confined in the first period for the BS-initiated channel occupancy and ii) the scheduled UL transmission is not time-aligned with a beginning of a second period for the UE-initiated channel occupancy, and
wherein:
the UE performs the scheduled UL transmission based on that the UE has already initiated a channel occupancy in the second period, and
the UE drops the scheduled UL transmission based on that the UE has not initiated the channel occupancy in the second period.
