1. A method by which a terminal performs communication in a wireless communication system, the method comprising:
receiving physical downlink control channel (PDCCH) configuration information and rate matching configuration information from a base station;
based on the PDCCH configuration information and the rate matching configuration information, identifying resource elements (REs) overlapping a rate matching resource from among REs included in PDCCH candidates; and
based on whether a number of ports of signals transmitted via the rate matching resource exceeds a preset value, monitoring a PDCCH candidate comprising the identified REs from among the PDCCH candidates.
