Abstract: A method for performing evolved multimedia broadcast and multicast service (eMBMS) counting efficiently in wireless systems is provided. The method includes receiving by a radio link control (RLC) layer of a User Equipment (UE), a Multicast Control Channel (MCCH) packet containing an MBMS counting request from a network. The RLC layer then transfers the MCCH packet to a Radio Resource Control (RRC) layer of the UE. The RRC layer processes the MBMS counting request and generating an MBMS counting response by and transmits an indication for successful reception of the MBMS counting request to the RLC layer. The RLC layer verifies if a subsequent MCCH modification boundary indication is received in a selected MCCH modification period and discards one or more subsequent MCCH packets received in a selected MCCH modification period if the MCCH modification boundary indication is not received from a physical layer.

Abstract: Systems and/or methods for handling Radio Frequency (RF) resources between a Multimedia Broadcast Multicast Services (MBMS) stack and a non-MBMS stack in a Dual SIM Dual Standby (DSDS) device. The method includes operations of receiving, by an arbitrator module, an MBMS configuration from the MBMS stack, calculating, by the arbitrator module, one or more available RF occasions and a duration of each of the one or more RF occasions based on MBMS configuration, updating the non-MBMS stack information on the availability of the one or more RF occasions along with the corresponding durations in absolute time, and receiving information from the non-MBMS stack on completion of operations utilizing the one or more available RF occasions.

Abstract: Embodiments herein disclose a method for MBS switching and continuity in a 5G wireless network. The method includes establishing, by a gNodeB, a MBS session with a UE. Further, the method includes providing, by the gNodeB, MBS to the UE during the MBS session. Further, the method includes detecting, by the gNodeB, that the at least one MBS is going to get suspended or deactivated. Further, the method includes sending, by the gNodeB, an indication to the UE indicating the at least one MBS going to get suspended or deactivated prior to suspension or deactivation of the at least one MBS at the UE.

Abstract: Embodiments herein disclose a method for operating a UE (100) comprising a plurality of SIMs (150). Further, the method includes sending a request message to obtain a time gap configuration from one of: a first network entity (200a) when the UE (100) is registered and connected with the first network entity (200a) through the first SIM (150a) and to the second network entity (200b) when the UE (100) is registered and connected to the second network entity (200b) through the second SIM (150b). Further, the method includes receiving a response message comprising the time gap configuration from one of: the first network entity (200a) and the second network entity (200b). Further, the method includes activating the time gap configuration when the UE (100) is connected to one of: the first network entity (200a) and the second network entity (200b).
