Abstract: Provided is a method for a terminal performing an RRC connection reestablishment process in a wireless communication system. The method comprises the steps of: the terminal moving from a first base station to a second base station; transmitting, to the second base station, an RRC connection reestablishment request message; receiving, from the second base station, an RRC connection reestablishment message, wherein the RRC connection reestablishment message includes a state conversion indicator indicating an RRC state into which the terminal should enter; and entering the RRC state corresponding to the state conversion indicator.

Abstract: Provided are a method for requesting, by a user equipment (UE), system information in a wireless communication system and a device supporting the same. The method may include: initiating a random access procedure; requesting system information from a base station (BS) in the initiated random access procedure; receiving, from the BS, a broadcast indication indicating that the requested system information is broadcast in the initiated random access procedure after requesting the system information from the BS; and stopping the initiated random access procedure.

Abstract: A method performed by a wireless device in a wireless communication system is discussed. The method includes receiving, by the wireless device, broadcast signaling from a network, wherein the broadcast signaling informs that the network supports a device-to-device (D2D) related information; after receiving the broadcast signaling, transmitting, by the wireless device, a message including the D2D related information based on a change of the D2D related information to the network; receiving, by the wireless device, D2D radio resources from the network via a dedicated signaling; and performing, by the wireless device, a D2D operation based on the D2D radio resources.

Abstract: A method for restarting a prohibit timer in a wireless communication system, the method performed by a user equipment (UE) includes starting the prohibit timer related to a transmission of power preference information; receiving, from a network, a handover message including a timer value; performing a handover procedure based on the received handover message; restarting the prohibit timer based on applying the received timer value included in the handover message; and stopping the prohibit timer based on whether the UE initiates radio resource control (RRC) re-establishment procedure while the prohibit timer is running. Further, upon initiating the RRC re-establishment procedure, the UE disables the transmission of the power preference information and stops the prohibit timer.

Abstract: Provided are a method of selecting configuration based on UE speed and a device supporting the method. According to one embodiment of the present invention, a method for selecting configuration based on UE speed in a wireless communication system includes: receiving a first configuration and a second configuration from a network; if the UE is able to measure a speed of the UE by using a global positioning system (GPS), selecting the first configuration, and scaling values in the first configuration based on the speed of the UE; and if the UE is not able to measure the speed of the UE by using the GPS, selecting the second configuration.

Abstract: As a channel busy ratio (CBR) is defined to measure the congestion of a PC5 interface in order to support an effective vehicle-to-everything (V2X) communication, an eNodeB (eNB) transmits CBR information of a sidelink channel to a user equipment (UE) for each resource pool used for V2X communication. The user equipment which has received the CBR information determines if there is a usable CBR and, if it is determined that there is no usable CBR, can use the received CBR information.
