A method of receiving a physical downlink control channel (PDCCH) according to an embodiment of the present disclosure may include receiving, from a base station, configuration information related to one or more search space sets for the PDCCH; and based on overlapping of one or more monitoring occasions in a plurality of control resource sets (CORESETs) with different QCL (quasi co-location) configurations for a spatial reception parameter, receiving, from the base station, the PDCCH in a first CORESET with a first QCL configuration for the spatial reception parameter and a second CORESET with a second QCL configuration for the spatial reception parameter among the plurality of CORESET. The first CORESET may be determined based on a predetermined priority rule, and the second CORESET may be determined as a CORESET associated with a second search space set linked to a first search space set associated with the first CORESET for transmission of the PDCCH, and the configuration information may include information on the link between the first search space set and the second search space set.
