1. A method of receiving, by a user equipment (UE), a physical downlink control channel (PDCCH) including one or more control channel elements (CCEs) in a wireless communication system, the method comprising:
receiving configurations for a plurality of search space (SS) sets including one or more common search space (CSS) sets and one or more UE-specific search space (USS) sets;
determining at least one monitoring SS set to be monitored by the UE in a specific slot configured with two or more of the plurality of SS sets, based on a first threshold related to a PDCCH candidate limit of the UE and a second threshold related to a CCE limit of the UE; and
receiving at least one PDCCH signal in the specific slot based on PDCCH candidates included in the determined at least one monitoring SS set,
wherein in determining the at least one monitoring SS set, based on that the one or more CSS sets include a CSS set for a multicast broadcast service (MBS) and that the CSS set for the MBS is configured in the specific slot, the UE:
determines, from among first CSS sets configured in the specific slot, to monitor all remaining first CSS sets except for the CSS set for the MBS; and
selects, until the UE reaches either the first threshold or the second threshold, second SS sets to be additionally monitored by the UE from among the CSS set for the MBS and USS sets configured in the specific slot, based on each SS set index.
