1. A method comprising:
performing, by a user equipment (UE), an initial access with a base station;
receiving, by the UE from the base station, at least one CORESET configuration information; and
monitoring, by the UE, a set of physical control channel (PDCCH) on a candidates in a CORESET configured based on the at least one CORESET configuration information,
wherein a duration of the CORESET on a time axis is 4 or more symbols,
wherein the CORESET comprises at least 2 sub-CORESETs, a duration of each of the at least 2 sub-CORESETs being smaller than the duration of the CORESET and a sum of durations of the at least 2 sub-CORESETs being same as the duration of the CORESET, and
wherein indexing of each of a plurality of control channel elements (CCEs) mapped to the CORESET is performed by alternating a first sub-CORESET and a second sub-CORESET of the at least 2 sub-CORESETs.
