Abstract: One embodiment of the present invention relates to a method and a device for transmitting and receiving a signal in a wireless communication system, the method comprising the steps of: performing a random access procedure; monitoring a physical downlink control channel (PDCCH) for an ON duration on the basis of a configured discontinuous reception (DRX) operation after performing the random access procedure; and operating an inactivity timer on the basis of the successfully received PDCCH for the ON duration. During the random access procedure, a random access preamble is transmitted in one or two physical random access channel (PRACH) slots. The one or two PRACH slots are determined from among N slots corresponding to a reference slot. A subcarrier spacing (SCS) setting value for the reference slot may be 2 on the basis of the SCS setting value applied to the N slots being 5 or 6.

Abstract: 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.
