1. A method of transmitting, by a base station, a plurality of physical downlink control channels (PDCCHs) in a wireless communication system, the method comprising:
receiving, from a user equipment (UE), UE capability information representing a number of simultaneously supportable beams;
transmitting, to the UE, independent layer joint transmission (ILJT)-related configuration information; and
transmitting, to the UE, the plurality of PDCCHs based on the ILJT-related configuration information,
wherein the ILJT-related configuration information includes information for the plurality of PDCCHs scheduling a plurality of physical downlink shared channels (PDSCHs) that are overlapped, a scheduling offset threshold value separately configured for the plurality of PDCCHs scheduling the plurality of overlapping PDSCHs, and information for a control resource set (CORESET) which is configured based on at least one index representing a group of CORESETs, and
wherein a number of the at least one index is determined based on the UE capability information.
