Classification: CPC H | IPC H

Claim 4:
5. A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a terminal, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) based on a first subcarrier spacing;
transmitting, to the terminal, a master information block (MIB) based on the first subcarrier spacing, wherein the MIB includes first information associated with a second subcarrier spacing for a physical downlink control channel (PDCCH) and second information associated with a resource for the PDCCH; and
transmitting, to the terminal, the PDCCH based on the second subcarrier spacing and the second information,
wherein the second subcarrier spacing is identified from one of a first subcarrier spacing set or a second subcarrier spacing set, based on the first information included in the MIB, and
wherein the first subcarrier spacing set corresponds to a lower frequency band and the second subcarrier spacing set corresponds to a higher frequency band.
