    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.

    Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method is provided. The method includes receiving, by a Next Generation Radio Access Network (NG-RAN) node, a multicast group paging message from an Access and Mobility Management Function (AMF) node, determining, by the NG-RAN node, one or more User Equipment (UE) that has to be page (e.g., multicast group paging) for the MBS multicast session activation notification based on the received multicast group paging message, performing, by the NG-RAN node, the multicast group paging for one or more determined UE, wherein the NG-RAN node pages the MBS multicast session activation notification to one or more determined UE.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods for managing a paging operation in a wireless network (1000) by a UE (100). The method includes receiving a paging message from a network device (200), where the UE (100) is in a Radio Resource Control (RRC) inactive state. Further, the method includes determining whether the UE (100) has received at least one of a core network (CN) paging and a group paging in the paging message. Further, the method includes sending at least one of a UE identity, an access type and a Temporary Mobile Group Identity (TMGI) to an upper layer upon determining that the UE (100) simultaneously receives the CN paging and the group paging in the paging message. Further, the method includes transiting the UE (100) into a Radio Resource Control (RRC) idle state from the RRC inactive state.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein are to provide a method and system for handling lower triggered mobility (LTM) of a base station. The method includes determining whether to configure lower layer triggered mobility (LTM) for a master cell group (MCG); determining whether to configure the LTM for a secondary cell group (SCG); transmitting, to a user equipment (UE), a configuration message including at least one of first LTM configuration information for the MCG and second LTM configuration information for the SCG, wherein the configuration message includes information about at least one channel state information (CSI) resource for configuring at least one candidate cell for the LTM.

    Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method for handling network energy saving (NES) in a wireless network is provided. The method includes receiving, by a user equipment (UE) a radio resource control (RRC) reconfiguration message from a network entity, wherein the RRC reconfiguration message includes at least one of a cell discontinuous reception (Cell-DRX) configuration and a cell discontinuous transmission (Cell-DTX) configuration for at least one serving cell, performing at least one of an activation and deactivation for at least one of the Cell-DRX configuration and the Cell-DTX configuration by at least one of the RRC reconfiguration message and a downlink control information (DCI) termed as DCI X, and handling the NES in the wireless network upon performing at least one of the activation and deactivation for at least one of the Cell-DRX configuration and the Cell-DTX configuration.
