Abstract: Methods and systems for handling power saving signals to improve power saving performance of UE. A method disclosed herein includes enabling, a User Equipment (UE), to monitor a Physical Downlink Control Channel (PDCCH) for downlink control information based on a reception of power saving signals from a Base Station with respect to a discontinuous-reception (DRX) cycle. The power saving signals include a Wake Up Signal (WUS), Go To Sleep (GTS) signal and PDCCH adaptation signal. The method further includes enabling the UE to monitor the PDCCH, if the WUS indicates presence of the PDCCH and enables the UE to skip the monitoring of the PDCCH during an On-duration of the DRX cycle, if the WUS indicates absence of the PDCCH. The method further includes enabling the UE to skip the monitoring of the PDCCH in an active time of the DRX cycle, on receiving the GTS signal.

Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method and a system for manage state transitions of a multicast broadcast service (MBS) user equipment (UE), manage a service continuity of the multicast UE, and manage packet data convergence protocol (PDCP) synchronizations of the multicast UE in a wireless network are provided. A radio resource control (RRC) connection resume procedure is initiated when point-to-multipoint (PTM) configurations are not available in a cell after cell selection and/or cell reselection, and the UE has at least one activated session in the RRC_INACTIVE state. The RRC connection resume procedure is also initiated when the cell after cell selection and/or cell reselection is an MBS control channel (MCCH)-less cell and the UE has at least one activated session (for example, indicated to monitor G-RNTI) in the RRC_INACTIVE state. Further, multicast MRBs are handled during motility by providing a mechanism for multicast reception across cells in the radio access network (RAN) notification area (RNA), where PDCP synchronizations are indicated or not indicated in the multicast session.
