receiving configuration information related to a search space;

determining PDCCH candidates to be monitored within a plurality of search spaces,

wherein the plurality of search spaces include UE-specific search spaces (USSs) and are configured for a plurality of control resource sets (CORESETs) based on the configuration information, and each search space includes one or more physical downlink control channel (PDCCH) candidates;

monitoring the PDCCH candidates to be monitored; and

receiving the DCI based on the monitoring,

wherein a first limit and a second limit related to the number of the PDCCH candidates to be monitored are predefined, the first limit is a value configured for a serving cell, the second limit is a value configured for a CORESET group related to a CORESET in which each space is configured, and the number of PDCCH candidates to be monitored is smaller than or equal to the first limit and the second limit, and

wherein the USSs are determined sequentially as the PDCCH candidates to be monitored in ascending order of index within a range that a cumulative number of PDCCH candidates included in each USS from the USS with the lowest index does not exceed the first limit and the second limit.
