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 method and apparatus for transmitting a physical random access channel (PRACH) in a wireless communication system is provided. A user equipment (UE) receives multiple PRACH configurations which include a first PRACH configuration for new radio access technology (NR) downlink/uplink (DL/UL) carrier in a NR band and a second PRACH configuration for a supplemental UL carrier in a long-term evolution (LTE) band, and transmits at least one of a first PRACH for accessing the NR DL/UL carrier in the NL band by using a first PRACH power based on the first PRACH configuration, or a second PRACH for accessing the supplemental UL carrier in the LTE band by using a second PRACH power based on the second PRACH configuration. The first PRACH configuration and the second PRACH configuration include different PRACH power configurations.

Abstract: The present specification provides an error detection method performed by a terminal in a wireless communication system, the method comprising: determining whether a minimum slot offset from a base station has been detected, wherein the minimum slot offset is a slot offset associated with an expectation that the terminal should receive a physical downlink shared channel (PDSCH) on the basis of at least one slot offset having a value equal to or greater than that of the minimum slot offset; detecting an error relating to detection of the minimum slot offset; and performing a fallback operation on the basis of the error detection.

Abstract: According to an embodiment of the present invention a user equipment (UE) may receive, in a first common frequency resource (CFR) associated with a first bandwidth part (BWP) which is an active BWP of the UE, first multicast/broadcast service (MBS) data; receive, in the first BWP, a physical downlink control channel (PDCCH) carrying downlink control information (DCI) including information regarding BWP switching; activate a second BWP based on the DCI; and receive second MBS data, wherein, based on that the active BWP has been changed from the first BWP to the second BWP and a second CFR different from the first CFR is associated with the second BWP, the UE activates the second CFR and receives the second MBS data in the second CFR.

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.
