1. A method performed by a User Equipment (UE) for management of Multicast-Broadcast Service (MBS) data reception, the method comprising:
receiving a first Discontinuous Reception (DRX) configuration mapped to an MBS, the first DRX configuration including a first timer for controlling activity of the UE for monitoring a Physical Downlink Control Channel (PDCCH) associated with a Group Radio Network Temporary Identifier (G-RNTI) of the MBS;
receiving a first Downlink (DL) assignment associated with the G-RNTI on the PDCCH;
identifying an unsuccessful reception of a Physical Downlink Shared Channel (PDSCH) that is scheduled by the first DL assignment and used for receiving data of the MBS;
starting the first timer after identifying the unsuccessful reception of the PDSCH;
enabling use of a Cell Radio Network Temporary Identifier (C-RNTI) to decode a second DL assignment while the first timer is running;
receiving a second DRX configuration that does not map to any MBS, the second DRX configuration including a second timer;
starting the second timer after identifying the unsuccessful reception of the PDSCH; and
enabling use of the C-RNTI to decode the second DL assignment while the second timer is running.
