1. A user equipment configured to operate in a wireless communication system, the user equipment comprising:
a processor configured to attempt to receive a synchronization signal and physical broadcast channel (PBCH) block (SSB) in SSB transmission candidate locations in a discovery reference signal (DRS) transmission window in an unlicensed band, wherein each of the SSB transmission candidate locations indicates a time point within the DRS transmission window, at which the user equipment is able to start to receive the SSB, wherein the DRS transmission window is a time interval in which a base station is able to transmit the SSB,
when the user equipment fails to receive a first SSB in a first SSB transmission candidate location in the DRS transmission window, the processor is configured to attempt to receive a second SSB in a second SSB transmission candidate location in the first DRS transmission window, which is located after the first SSB transmission candidate location in the DRS transmission window, wherein the first SSB is identified by a first index, the second SSB is identified by a second index, and the first index and second index have a same value, and
when the user equipment succeeds to receive the first SSB in the first SSB transmission candidate location, the processor is further configured not to attempt to receive the second SSB in the DRS transmission window, and
wherein a subcarrier spacing used for transmitting the SSB is 15 kHz or 30 kHz.
