Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method for handling segmentation in a converged layer 2 (L2) communication network is provided. The method includes assigning, by a converged L2 of a transmitter, a L2 sequence number (SN) to a protocol data unit (PDU). The L2 SN includes at least one of a last segment indication (LSI) indicating a presence of a last service data units (SDU) of the complete PDU, a length indicator exist (LIE) indicating a presence of a length indicator (LI) after a L2 header, or a SI indicating a segmentation status or stage of the complete PDU, receiving, by a medium access control (MAC) layer of the transmitter, a grant opportunity or a transmission opportunity for transferring the PDU available at the converged L2, and sending the PDU to a lower layer of the transmitter for transmission to a receiver with or without segmentation based on the grant or a transmission opportunity.

Abstract: Embodiments herein provide a method and apparatus for handling bearer type change and user plane in a wireless communication supporting multi radio multi connectivity (MR-MC). A new bearer type is introduced to benefit from the increased radio resources of an additional network node. There is a method added to handle bearer type change that is applicable to both existing bearer types and new bearer type. The method includes suspending and resuming the bearer configuration at all layers, defining actions that take place at each layer during the bearer type change. With this mechanism, signaling overhead and latency is bearer establishment is reduced.

Abstract: The various embodiments herein disclose methods and systems for uplink scheduling schemes for low-earth orbit (LEO) satellite based Non-Terrestrial Network (NTN). According to an embodiment, a zone-based scheduling (ZBS) scheme is described where the coverage area may be divided into a plurality of zones and independent scheduling-offsets may be allocated for each of the zones. The ZBS scheme improves upon the overall user latency by reducing the K2 and cell offset delay for low-propagation delay users within the NTN cells. At the same time, the impact of differential doppler may also be mitigated with such a zone-based allocation strategy.

Abstract: Embodiment herein provides a method for handling packet duplication and resumption of Radio Bearers (RBs) in a wireless communication system. The method includes receiving, by a base station, a Radio Resource Control (RRC) connection reestablishment request message from a User Equipment (UE). Further, the method includes sending, by the base station, a RRC connection reestablishment message on a default Signaling Radio Bearer (SRB) to the UE. The RRC connection reestablishment message is sent on the default SRB for allowing a re-establishment of Dedicated Radio Bearers (DRBs), a first SRB, and a second SRB without waiting for reception of a RRC reestablishment complete message from the UE. Further, the method includes receiving, by the base station, the RRC reestablishment complete message from the UE.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The embodiments herein relate to wireless communication system and more particularly relates to a method for coordination of Radio Resource Control (RRC) configurations between interworking nodes in dual connectivity in wireless communication system. The method includes determining, by a secondary node, whether a signaling radio bearer (SRB) of a secondary node is pre-configured in a secondary cell group (SCG), deciding, by the secondary node, to perform secondary node modification to a user equipment (UE) in response to determining that the SRB of the secondary node is pre-configured, transmitting, by the secondary node, a RRC connection reconfiguration message to the UE without coordinating with a master node and receiving, by the secondary node, a RRC connection reconfiguration complete message from the UE.
