The operation method may include identifying whether an active bandwidth part (BWP) is the same as a BWP for a multicast and broadcast service (MBS) selected by the UE, transmitting, to a base station, a message including information about the MBS when the active BWP is different from the BWP for the MBS, receiving, from the base station, based on the message, information for providing a service based on the MBS, and receiving the MBS, based on the information for providing the service based on the MBS.

The present invention relates to a method of performing data transmission in a wireless communication system. Especially, the method includes the steps of transmitting data on a first bandwidth part (BWP) among a plurality of BWPs configured for data transmission in a radio resource control (RRC) inactive state (RRC_INACTIVE); switching from the first BWP to a second BWP among the plurality of BWPs, when a positive response message of the data is not received from the network within a pre-defined period; and transmitting the data on the second BWP.

A wireless device receives configuration parameters indicating duration values for skipping physical downlink control channel (PDCCH) monitoring on a bandwidth part (BWP). The duration values are from: first values in response to the BWP having a first subcarrier spacing (SCS) and second values in response to the BWP having a second SCS, with each value of the second values being equal to multiplication of a respective value, of the first values, and a same granularity value. The wireless device may receive a downlink control information (DCI) indicating skipping PDCCH monitoring on the BWP for a time duration based on a duration value of the duration values. The wireless device may skip monitoring the PDCCH on the BWP for the time duration, based on the DCI.
