Classification: CPC nan | IPC H

Claim 0:
1. A base station in a wireless communication system, the base station comprising:
a processor configured to:
transmit a synchronization signal and PBCH (physical broadcast channel) block (SSB) in SSB transmission candidate locations in a discovery reference signal (DRS) transmission window in an unlicensed band,
terminate a transmission of the SSB before at least one orthogonal frequency division multiplexing (OFDM) symbol from a boundary between a slot in which the transmission of SSB is performed and a slot subsequent to the slot in which the transmission of the SSB is performed,
wherein the DRS transmission window is a time interval in which the base station is able to transmit the SSB,
wherein each of the SSB transmission candidate locations indicates a time point at which the base station is able to start transmitting the SSB within the DRS transmission window,
wherein the maximum number of SSBs capable of being transmitted by the base station in a first DRS transmission window is limited, and
wherein a subcarrier spacing used for the transmission of the SSB is 15 kHz or 30 kHz.
