Claim 12:
13. A base station in a wireless communication system, the base station comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
transmit, to a terminal, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) based on a first subcarrier spacing,
transmit, 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
transmit, 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.
