Abstract: The present disclosure provides a method for receiving a downlink signal on the basis of a random-access channel procedure (RACH procedure) by a terminal in an unlicensed band. Specifically, the method may comprise: on the basis of a power ramping counter, configuring transmission power for message A including a first physical random-access channel (PRACH) and a first physical uplink shared channel (PUSCH); on the basis of the transmission power, transmitting message A to a base station; and receiving contention resolution-related message B from the base station in response to message A, wherein an increase is made on the basis that a transmission spatial beam for transmission of message A is configured to be identical to a transmission spatial beam related to transmission of a PRACH preceding message A.

Abstract: A method and apparatus for monitoring a signal in a wireless communication system disclosed herein may perform multi-slot physical downlink control channel (PDCCH) monitoring for a subcarrier spacing (SCS) of 480 kHz or 960 kHz. The multi-slot PDCCH monitoring refers to PDCCH monitoring configured to include a slot interval between PDCCH monitoring occasions in consideration of an increase in a user equipment (UE) burden when monitoring a PDCCH in consecutive slots.

Abstract: A UE performs PDCCH monitoring for at least one serving cell by switching a search space set of a first SSSG to a search space of a second SSSG at a search space set group (SSSG) switching time. When PDCCH monitoring is performed in a unit of a slot-group for the at least one serving cell, the UE determines the SSSG switching time based on a largest Xs value among Xs values for the at least one serving cell.
