Claim 0:
1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
detecting a synchronization signal/physical broadcast channel (SS/PBCH) block including 15 kHz subcarrier spacing-based offset information;
determining a control resource set (CORESET) for Type0-physical downlink control channel (PDCCH) common search space (CSS) set based on the SS/PBCH block,
wherein a subcarrier offset between the CORESET for Type0-PDCCH CSS set and the SS/PBCH block is determined based on the 15 kHz subcarrier spacing-based offset information;
monitoring the CORESET for Type0-PDCCH CSS set,
wherein, based on the SS/PBCH block detected in a shared spectrum, a frequency of the SS/PBCH block is separated from a synchronization raster by k*30 kHz, where k is an integer greater than or equal to zero, and one least significant bit (LSB) of the subcarrier offset is ‘0’.
