1. A base station (BS) in a wireless communication system, the BS comprising:
a processor configured to:
identify a set of discovery signals and channels (DSCH) including a set of synchronization signals and physical broadcast channel (SS/PBCH) blocks;
identify a DSCH transmission timing configuration (DTTC) including a periodicity of a transmission window and a duration of the transmission window, wherein the DTTC is identified for a transmission of the set of DSCH;
identify a type of a channel access procedure based on a duration of the set of DSCH; and
perform the type of channel access procedure based on a channel sensing for the set of DSCH based on the identified DTTC; and
a transceiver operably coupled to the processor, the transceiver configured to transmit, to a user equipment (UE), the set of DSCH in an unlicensed band based on a result of the channel sensing.
