Abstract: When a specific case occurs, user equipment can initiate a tracking area update (TAU) step by transmitting a TAU request. If the user equipment is using a control plane connection for the transport of user data when a radio resource control (RRC) connection failure occurs and there is no pending signaling or uplink user data, the specific case can be applied to a case in which it is indicated, to a network, that downlink data reception subsequent to the uplink data transmission is predicted.

Abstract: Provided are a method for a terminal applying an offset to a measurement report triggering condition in a wireless communication system, and a device supporting same. A terminal may measure the quality of a serving cell, measure the quality of a neighboring cell, compare the measurement type of the serving cell with the measurement type of the neighboring cell, and if the measurement type of the serving cell is different from the measurement type of the neighboring cell, apply an offset to a measurement report triggering condition. The measurement type may be any one of a broadband RS-SINR measurement or a narrowband RS-SINR measurement.

Abstract: A method by which a terminal performs frequency measurement in a wireless communication system, and a device for supporting the same are provided. The terminal receives an intra-frequency measurement threshold value and an inter-frequency measurement threshold value for a reduced performance measurement group, measures a signal level of a serving cell, and performs frequency measurement on the basis of the measured signal level of the serving cell and the received threshold values, wherein the intra-frequency measurement threshold value can be larger than the inter-frequency measurement threshold value for the reduced performance measurement group.

Abstract: According to one embodiment of the present disclosure, there is provided a method in which a terminal transmits position measurement information in a radio communication system. The method that is performed by the terminal includes triggering a beam positioning mechanism, receiving a beam positioning-related signal from a base station, measuring the beam positioning-related signal, acquiring position measurement information based on the measured beam positioning-related signal, and transmitting the acquired position measurement information to the base station. The position measurement information is acquired based on beamforming configuration.

Abstract: Provided are a method for a terminal controlling uplink power in a rando access channel-less (RACH-less) handover, and an apparatus for supporting same. The method may comprise the steps of: receiving, from a source base station, an RRC connection reconfiguration message including an uplink grant; transmitting, to a target base station using a first transmission power, an RRC connection reconfiguration complete message, on the basis of the uplink grant; receiving, from the target base station, a NACK corresponding to the RRC connection reconfiguration complete message; ramping the first transmission power to a second transmission power; and transmitting the RRC connection reconfiguration complete message using the ramped second transmission power.

Abstract: A method handling a link failure by a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of suspending at least one data radio bearer (DRB) upon detecting an occurrence of the link failure; transmitting, to a specific cell, a radio resource control message indicating the occurrence of the link failure; receiving a response message as a response of the radio resource control message from the specific cell; and resuming the at least one suspended DRB.
