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.
