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: Embodiments disclosed herein relate to methods and systems for shared processing for simultaneous MBS and unicast reception. The methods disclose enhanced interest indication signaling for simultaneous MBS and unicast reception from one or more networks. The methods include receiving, from a primary cell (PCell) of a serving base station, a system information block (SIB) including information on a transmission of a MBS interest indication (MII) message for a MBS broadcast reception on a non-serving cell; in case a MII message setting condition associated with the non-serving cell is satisfied, setting a content of the MII message; and based on the information, transmitting, to the serving base station, the MII message.

Abstract: A method for handling a Discontinuous reception (DRX) operation by a user equipment (UE) in a wireless network is provided. The method includes detecting an event. The event includes at least one of a hybrid automatic repeat request (HARQ) feedback being disabled, a HARQ feedback not being configured, or an unsuccessful multicast transport block (TB) decoding. Further, the method includes performing an action based on the detected event. In an example, the action includes adding an additional timing duration to at least one preconfigured DRX timer value and staying awake by the UE while the preconfigured timer is running. The action includes staying awake by the UE in spite of a multicast DRX active time being over and continuing to monitor for potential HARQ retransmission.
