Abstract: Provided are: a method by which a terminal transmits a system information request in a wireless communication system; and a device for supporting the same. The method comprises the steps of: receiving, from a first cell, a list of a frequency and a cell to which a system information request can be transmitted; and determining whether to transmit, to the first cell, the system information request on the basis of the list, wherein the system information request can be transmitted only to a cell included in the list or to a cell using a frequency included in the list.

Abstract: Provided are a device-to-device (D2D) operation method and device which are performed by a terminal in a wireless communication system. The method comprises: receiving D2D configuration information indicating a plurality of resources which can be used for a D2D operation from a network; selecting a specific resource from among the plurality of resources; and performing the D2D operation with another terminal using the selected specific resource, wherein the specific resource is selected on the basis of a reference signal received power (RSRP) which the terminal has received from the network.

Abstract: Provided are a method for keeping, by a user equipment (UE), a secondary cell group (SCG) configuration in a wireless communication system, and an apparatus supporting the same. The method may include: receiving radio access network (RAN) paging message from a base station; determining whether or not to keep a SCG configuration stored in the UE, based on the RAN paging message; and if the RAN paging message includes information related to a secondary base station, keeping the SCG configuration in an RRC resume procedure.

Abstract: An eNodeB (eNB) receives a first paging message including a first user equipment (UE) identity (ID) from a mobility management entity (MME). The eNB checks whether a UE context mapped to the first UE ID is present or not. If it is checked that the UE context mapped to the first UE ID is present, the eNB transmits a second paging message including a second UE ID, which replaces the first UE ID, to a UE.

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: An in-vehicle terminal engaged in vehicle-to-everything (V2X) communication, especially vehicle-to-vehicle (V2V) communication, establishes a reporting cycle on the basis of the speed of the in-vehicle terminal, and transmits geographic information of the in-vehicle terminal to a network cyclically on the basis of the reporting cycle. That is, the reporting cycle may be shortened as the in-vehicle terminal speed increases, or may be lengthened as the in-vehicle terminal speed decreases.

Abstract: Provided are a method for transmitting, by a base station in a wireless communication system, a vehicle to everything (V2X) message, and an apparatus for supporting the same. The base station may receive broadcast area information indicative of areas to which the V2X message will be broadcast, from a multi-cell coordination entity (MCE), receive the V2X message from a terminal, and transmit the received V2X message to a neighboring base station. Provided are a method for transmitting, by a V2X server in a wireless communication system, a vehicle to everything (V2X) message, and an apparatus for supporting the same. The V2X server may receive the V2X message transmitted by a base station from a serving/packet-gateway (S/P-GW), determine a broadcast of the received V2X message, and transmit the V2X message to a base station that belongs to the same multimedia broadcast single frequency network (MBSFN) area as the base station.

Abstract: A method and apparatus for deactivating a cell of an unlicensed carrier in a wireless communication system is provided. A user equipment (UE) deactivates a second cell when one of events occurs, and reports information on the second cell to a first cell. The first cell is a first serving cell on a licensed carrier, and the second cell is a second serving cell on the unlicensed carrier.

Abstract: Provided are a measurement reporting method of a terminal in which a primary cell is set and a terminal apparatus using the measurement reporting method. The method comprises: a step for adding a secondary cell; a step for determining whether the secondary cell is applicable to related measurement; and a step for determining whether the secondary cell is included in a cellsTriggeredList, wherein when the secondary cell is not applicable to the related measurement and the secondary cell is included in the cellsTriggeredList, the secondary cell is removed from the cellsTriggeredList.
