1. A method performed by a user equipment (UE), the method comprising:
receiving, via higher layer signaling, control resource sets (CORESET) configuration information including frequency resource allocation information and offset information on a frequency domain, wherein the frequency resource allocation information includes a bitmap of a plurality of resource block (RB) groups and the offset information indicates a frequency offset in a unit of an RB;
identifying the CORESET, based on the bitmap of the plurality of RB groups and the frequency offset in the unit of the RB; and
monitoring downlink control information based on the identified CORESET,
wherein a location of a first RB in the CORESET is identified based on a summation of an index of a start RB among a plurality of RBs included in a bandwidth part configured for the UE and the frequency offset, and
wherein the CORESET is identified based on the bitmap, from the identified location of the first RB.
