1. A method performed by a terminal in a wireless communication system, the method comprising:
obtaining a synchronization signal block (SSB) transmitted by a base station;
obtaining a master information block (MIB) from the SSB;
identifying a control resource set (CORESET) and a search space based on the MIB:
obtaining downlink control information (DCI) by monitoring a physical downlink control channel (PDCCH) based on the CORESET and the search space;
obtaining information on resources of a physical downlink shared channel (PDSCH) carrying a system information block (SIB) related to machine type communication (MTC) based on the DCI; and
obtaining the SIB related to MTC on the PDSCH, based on the information,
wherein in case that the CORESET and the search space are commonly configured for both a PDCCH scheduling an SIB related to a legacy fifth generation (5G) service and the PDCCH scheduling the SIB related to MTC, cyclic redundancy check (CRC) of the DCI is scrambled by a machine type communication-radio network temporary identifier (MTC-RNTI).
