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: Embodiments herein provide method for multicast session notification signalling and procedure in wireless network (1000) by UE (100). In an embodiment, the method includes receiving a signal related with a multicast and broadcast service (MBS) session in a radio resource control (RRC) connected state; in case that the UE (100) transits from the RRC connected state to one of a RRC idle state or a RRC inactive state and determines to join in at least one MBS session, monitoring a message for a group notification related with the at least one MBS session on a physical downlink control channel (PDCCH); based on a detection of the paging message, identifying a temporary mobile group identity (TMGI) indicating one of the at least one MBS session included in the paging message; and forwarding the identified TMGI to an upper layer.
