    Abstract: Embodiments herein provide methods and systems for managing and optimizing reception of SCPTM services. The services can be prioritized based on the attributes of the services. Based on the priorities the services can be received if there is a conflict in scheduling the reception of the services. The services can be scheduled in multiple RF carriers, if a single RF carrier cannot support receiving all the services to be received. The number of services that can be supported for reception can be informed to a network, which can optimize the scheduling of the services. The network can multiplex plurality of services in a single G-RNTI. The variations in SC-MCCH duration of a service can be known by monitoring DCI at modification period boundaries of a service.

    Abstract: Methods and apparatus are provided for HFN synchronization in a wireless communication system. If re-establishment of an RLC entity occurs during a pending RLC reset procedure, the pending RLC reset procedure is aborted and the re-establishment of the RLC entity is performed. A first RC variable included in a RESET PDU is incremented. The pending RLC reset procedure is restarted. The RESET PDU including the incremented first RC variable is transmitted. A RESET ACKnowledgement (ACK) PDU for the RESET PDU including a second RC variable is received. The second RC variable included in the received RESET ACK PDU is checked and the received RESET ACK PDU is accepted based on the checking result.

    Abstract: Methods and systems for handling power saving signals to improve power saving performance of UE. A method disclosed herein includes enabling, a User Equipment (UE), to monitor a Physical Downlink Control Channel (PDCCH) for downlink control information based on a reception of power saving signals from a Base Station with respect to a discontinuous-reception (DRX) cycle. The power saving signals include a Wake Up Signal (WUS), Go To Sleep (GTS) signal and PDCCH adaptation signal. The method further includes enabling the UE to monitor the PDCCH, if the WUS indicates presence of the PDCCH and enables the UE to skip the monitoring of the PDCCH during an On-duration of the DRX cycle, if the WUS indicates absence of the PDCCH. The method further includes enabling the UE to skip the monitoring of the PDCCH in an active time of the DRX cycle, on receiving the GTS signal.

    Abstract: The present disclosure describes methods of operating user equipment in 5G NR communications system. In accordance with some of the embodiments, the method comprises detecting a condition related to the user equipment (UE) while in one of a radio frequency (RF) inactive state and a cell handover, the condition indicating one of (a) the UE is not in reception of signaling information from a serving base station during the RF inactive state and (b) the UE is out of synchronization with the serving base station; determining an event related to one of transmission of data by the UE, reception of data by the UE, and radio resource management (RRM) measurement by the UE in conjunction with the detected condition; and applying one or more of (a) a blind downlink control information (DCI) decoding, (b) a static DCI configuration and (c) a dynamic DCI configuration based on the determination to enable the UE to at least one of (a) receive the signaling information, (b) receive the data, and (c) perform radio resource management (RRM) measurement.

    Abstract: A communication method and a system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT) are provided. The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments allow sending interest indication, by a user equipment (UE), to a 5G network, to indicate whether the UE is interested in receiving multicast and broadcast services (MBS) and/or MBS that are being currently received by the UE. Embodiments provide a mechanism to send interest indication.
