Abstract: A method and apparatus to support XR services is provided. Method for supporting XR services includes triggering a delay status report (DSR) for a one or more logical channels, triggering a scheduling request (SR) in case that uplink resource available for new transmission is not enough to accommodate the DSR medium access control (MAC) control element (CE) and its subheader as a result of logical channel prioritization, transmitting the SR based on SR configuration, starting a prohibit timer for the SR, and stopping the prohibit timer for the SR in case that a specific delay-critical data is transmitted. The specific delay-critical data is a delay-critical data that has not been transmitted. The delay-critical data comprises packet data convergence protocol (PDCP) Service Data Units (SDUs) that belongs to a Protocol Data Unit (PDU) set of which at least one PDCP SDU has the remaining time till expiry of a discard timer less than a remaining time threshold. The discard timer starts for a PDCP SDU when the PDCP SDU arrives at PDCP entity. The remaining time threshold is configured based on a radio resource control message.

Abstract: The present invention provides a method and system for implementing handover in NR networks, addressing the challenges associated with mobility management and ensuring efficient and reliable communication. The proposed solution leverages advanced algorithms and protocols to enhance the handover procedure, minimizing latency and reducing the likelihood of connection drops. By employing both network-controlled and UE-controlled handover mechanisms, the invention ensures robust and adaptive mobility management, catering to various network scenarios and user requirements. The proposed solution enables the terminal and the base station to perform appropriate type of synchronous reconfiguration in a given situation.

Abstract: A technique for managing TCI states in conjunction with LTM operations is provided. The technique comprises first updating of activated TCI states for a cell based on a first type TCI state activation/deactivation MAC CE, final updating of TCI states for the cell based on a LTM cell switch command MAC CE and subsequent updating of TCI states for the cell based on a second type TCI state activation/deactivation MAC CE.

Abstract: A method and apparatus for data transfer in RRC_INACTIVE state is provided. Method for data transfer in RRC_INACTIVE state includes initiating the second resume procedure, starting a first timer, receiving a RRCResume and stopping the first timer. Buffer status reporting is performed based on a first BSR configuration and a first LCG if the first timer is running and performed based on a second BSR configuration and the first LCG if the first timer is not running.

Abstract: Aspects of the present disclosure are to address the problems of performing time-based reconfiguration in mobile network. The method of the terminal includes receiving a first system information, receiving a second system information, receiving a RRC reconfiguration message, triggering a TAR before the first time point based on the first NTN configuration in the second scheduling information, and triggering the TAR after the first time point based on the second NTN configuration in the second scheduling information. The TAR comprises a timing advance field indicating a timing advance value applied by the terminal. The second system information comprises the first NTN configuration and the second NTN configuration.
