Abstract: According to an embodiment of the present disclosure, a user equipment (UE) may receive downlink control information (DCI) in a first fixed frame period (FFP) for frame based equipment (FBE) from a base station (BS), and perform a channel access procedure for a scheduled uplink (UL) transmission based on the DCI. In a first state in which it is indicated that the scheduled UL transmission is related to channel occupancy initiated by the BS, and the UE should perform channel sensing for the scheduled UL transmission, the UE may perform the channel access procedure for the scheduled UL transmission based on whether a resource for the scheduled UL transmission allocated by the DCI is confined within the first FFP in which the DCI is received.
