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: Methods and systems for RRC state maintenance for receiving multicast and broadcast services. Embodiments detect, by a UE, MBS transmission and/or reception from MAC entities associated with the UE, when the UE is operating in RRC_CONNECTED state. If expiry of a data inactivity timer, which is started on determining the MBS transmission and/or MBS reception, is detected, upper layer in the UE can be informed about the expiry of the data inactivity timer. Thereafter, the UE transitions to RRC_IDLE or RRC_INACTIVE states. A MBS specific data inactivity timer can be configured on determining the MBS transmission and/or MBS reception; and if the MBS specific data inactivity timer expires, the upper layers facilitate transition to the RRC_IDLE or RRC_INACTIVE states. The UE can receive MBS configuration or commands, from a network, to remain in RRC_CONNECTED state, transition to RRC_CONNECTED state, or transition to RRC_IDLE or RRC_INACTIVE states.

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.
