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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for allocating priorities to a logical channel group implicitly in a D2D communication system, the method comprising: receiving information including N numbers of priority lists in order of increasing logical channel group identity from an eNB, associating each of the N numbers of priority lists with each of the N numbers of logical channel groups in an order corresponding to a sequential order of the information, when a sidelink logical channel with a first priority is configured, allocating the sidelink logical channel with the first priority to a logical channel group associated with the first priority.
