The method includes, transmitting, by UE (101), transition request message to network apparatus for state change from RRC-inactive state to RRC-connected state. Further, method includes, receiving signaling message from network apparatus in response to transition request message indicating to transit. Further, method includes, invoking protocol layer reset operation at MAC layer when UE (101) is configured to receive MBS multicast in the RRC-inactive state. Further, method includes, determining whether RRC setup message and RRC resume message is received and protocol layer reset operation at MAC layer is invoked. Further, method includes, performing protocol layer reset operation at MAC layer during transition from RRC-inactive state to RRC-connected state, when RRC setup message and RRC resume message is received and protocol layer reset operation at MAC layer is invoked thereby enhancing the reliability and continuity for MBS reception."
