Abstract: Example embodiments herein provide methods and Dual SIM Dual Standby (DSDS) devices including a first Subscriber Identity Module (SIM) and a second SIM for managing data communication. The methods include establishing, by the DSDS device, a Radio Resource Control (RRC) connection over the first SIM and performing data communication with a network entity. Further, the methods include detecting, by the DSDS device, an activity upcoming over the second SIM. Further, the methods include transmitting, by the DSDS device, a connection suspend indication to the network entity to suspend the data communication over the first SIM, wherein the connection suspend indication is transmitted on one of a Layer-1 control signaling channel, a Layer-2 control signaling channel, and a Layer-3 control signaling channel.

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: A method for MCCH acquisition in a 5G wireless network (1000) by a UE (100) includes: receiving, by the UE, a MCCH change notification from the gNodeB over a PDCCH. Further, the method includes detecting whether at least one of the UE is interested to receive a new MBS and the UE is already receiving an MBS. Further, the method includes determining the start of the new MBS session for the new MBS by reading the first bit of the MCCH change notification in response to detecting that the UE is interested to receive the new MBS, or determining the modification to the MBS session configuration of the ongoing MBS session by reading the second bit of the MCCH change notification in response to detecting that the UE is already receiving the MBS.

Abstract: The present subject matter refers targeting paging reduction to improve upon power consumption performance for the user equipment in wireless networks. The methods and systems are disclosed where indication signal is applied for idle/inactive mode UEs. In one embodiment of the present disclosure, an indication signal is introduced for idle/inactive mode UEs for paging reception. In another embodiment, the group of UEs may be divided into plurality of paging sub-groups of UEs having common paging occasion and each paging sub-group be assigned a paging sub-group ID. This paging sub-group ID may be incorporated in the indicating signal to reduce paging reception.
