摘要： A method and an apparatus for monitoring a signal in a wireless communication system, disclosed in the present disclosure, perform PDCCH monitoring based on a configuration regarding a search space set. The PDCCH monitoring may be performed in units of slot-groups and performed only in a certain number of consecutive slots in a period given by a periodicity and an offset. When a duration related parameter indicating the number of consecutive slots in which the search space may exist is absent in the configuration, the certain number is determined based on the size of a slot-group configured for the search space set.
