    Abstract: Embodiments herein disclose a method for performing a handover in a wireless communication network. The method includes performing, by a network, a Packet Data Convergence Protocol (PDCP) version change for one or more radio bearers to switch from a first PDCP entity to a second PDCP entity. Further, the method includes receiving, by a User Equipment (UE), at least one of a PDCP version change indication and security key change indication from the network. Furthermore, the method includes performing, by the UE, a PDCP version change to switch from the first PDCP entity to the second PDCP entity for a configured radio bearer in response to receiving the PDCP version change indication.

    Abstract: Embodiments herein provide a method for handling a user plane by a UE configured for dual connectivity operation. The method includes receiving a RRC reconfiguration message including one or more Layer 2 indications and a Layer 2 configuration corresponding to one or more radio bearers from one of a MN and a SN involved in a dual connectivity operation of the UE. Further, the method includes performing, by the UE, one of: reestablishing of a RLC entity and a data recovery procedure for a PDCP entity corresponding to the radio bearer based on the one or more Layer 2 indications and the Layer 2 configuration received in the RRC reconfiguration message, and reestablishing of a RLC entity and reestablishing of a PDCP entity corresponding to the radio bearer based on the one or more Layer 2 indications and the Layer 2 configuration received in the RRC reconfiguration message.

    Abstract: An example security processing method includes receiving data packets at a packet data convergence protocol (PDCP) layer from an upper layer and parsing header information of each of the data packets to determine a length of each of the plurality of headers within the corresponding header information and whether a security header is present or absent in the corresponding data packets. The method further includes identifying corresponding header information of the data packets in which the security header is present based on the determination. The method further includes encrypting, based on the determined header lengths, only each of the plurality of headers of the identified corresponding header information in which the security header is present, and thereafter transmitting the one or more data packets to a lower layer after adding information regarding each of the encrypted headers along with their encryption length into a PDCP header.

    Abstract: A method for managing a wireless communication between user equipment (UE) by a UE in a communication system, the method comprising: receiving, from a base station (BS), a first signalling message to configure a report of assistance information for the wireless communication related to a vehicular service; transmitting, to the BS, the assistance information based on the first signalling message, wherein the assistance information comprises at least one of a period and timing offset of a data arrival and a data size; receiving, from the BS, a second signalling message comprising at least two semi-persistent scheduling (SPS) configurations for the wireless communication based on the assistance information; and performing the wireless communication with radio resources corresponding to the at least two semi-persistent SPS.
