Claim 0:
1. A method of performing a channel access procedure in a shared spectrum by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, in a first period, downlink control information (DCI) from a base station (BS); and
performing, based on the DCI, a channel access procedure for a scheduled uplink (UL) transmission,
wherein the scheduled UL transmission is associated with a channel occupancy that is initiated by the BS, and the UE is configured to perform the scheduled UL transmission after sensing,
wherein, for the scheduled UL transmission, the UE performs a first procedure related to a cross-period scheduling or a second procedure related to an intra-period scheduling based on whether the scheduled UL transmission is confined within the first period where the DCI is received, and
wherein a first carrier for the DCI reception and a second carrier for the scheduled UL transmission are different from each other, and the UE performs the second procedure related to the intra-period scheduling based on that the scheduled UL transmission is confined within the first period.
