1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) based on a first subcarrier spacing;
receiving, from the base station, 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;
identifying, based on the first information included in the MIB, the second subcarrier spacing for the PDCCH from one of a first subcarrier spacing set or a second subcarrier spacing set, wherein the first subcarrier spacing set corresponds to a lower frequency band and the second subcarrier spacing set corresponds to a higher frequency band; and
receiving, from the base station, the PDCCH based on the second subcarrier spacing and the second information.
