1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a synchronization signal/physical broadcast channel (SS/PBCH) block in a candidate resource region among a plurality of candidate resource regions for the SS/PBCH block;
obtaining a PBCH based on the SS/PBCH block; and
monitoring a physical downlink control channel (PDCCH) based on at least one control resource set (CORESET), wherein the at least one CORESET is determined based on the PBCH,
wherein two candidate resource regions among the plurality of candidate resource regions are pre-defined within a time interval, wherein the time interval has a duration of 14 consecutive orthogonal frequency division multiplexing (OFDM) symbols indexed by OFDM symbol indices n=0, 1, 2, . . . , 13,
wherein a first candidate resource region among the two candidate resource regions has an initial OFDM symbol at OFDM symbol index n=2 in the time interval, and a duration of the first candidate resource region is 4 symbols,
wherein a second candidate resource region among the two candidate resource regions has an initial OFDM symbol at OFDM symbol index n=9 in the time interval, and a duration of the second candidate resource region is 4 symbols,
wherein a first CORESET for the PDCCH has an initial OFDM symbol at OFDM symbol index n=0 in the time interval, and a duration of the first CORESET is 2 symbols, and
wherein a second CORESET for the PDCCH has an initial OFDM symbol at OFDM symbol index n=7 in the time interval, and a duration of the second CORESET is 2 symbols.
