1. A method performed by a user equipment (UE), the method comprising:
transmitting a random access preamble to a base station (BS);
receiving a random access response from the BS; and
performing a scheduled uplink (UL) transmission in shared spectrum based on the random access response,
wherein the scheduled UL transmission is indicated as being associated with channel occupancy initiated by the BS, and the UE is indicated to perform the scheduled UL transmission based on sensing,
wherein, based on the random access response and the scheduled UL transmission being configured within different periods, the UE:
performs a specific procedure for detecting a downlink (DL) transmission from the BS, and
performs the scheduled UL transmission based on that the DL transmission from the BS has been detected through the specific procedure, and
wherein, based on the random access response and the scheduled UL transmission are being configured within a same period, the UE:
performs the scheduled UL transmission without performing the specific procedure for detecting the DL transmission from the BS.
