Abstract: A method for performing positioning for estimating position in a wireless communication system according to the present invention comprises transmitting, by a first UE, a positioning request message for performing the positioning to an eNB; transmitting, by the eNB, an anchor request message to neighboring UEs within a cell to find UEs which may become a second UE; receiving, the eNB, an anchor response message corresponding to a response to the anchor request message from at least one UE from among neighboring UEs within the cell; and determining, by the eNB, the second UE based on the received anchor response message.

Abstract: An embodiment of the present invention relates to a method in which a first terminal transmits/receives a message including platoon information in a wireless communication system. The method include: a step for receiving, by a first terminal, resource information from a second terminal in a terminal group forming a platoon; a step of transmitting, by the first terminal, a Cooperative Awareness Message (CAM) including the platoon information after receiving the resource information, wherein when the platoon information is for a terminal not belonging to the terminal group, the first terminal transmits the CAM message through a resource instructed in the resource information.

Abstract: Disclosed are a method for controlling power and an apparatus therefor in a wireless communication system supporting device-to-device (D2D) communication. Specifically, a method for a terminal for controlling the transmission power of a physical sidelink discovery channel (PSDCH) in a wireless communication system supporting D2D communication comprises the steps of: calculating the sum of reception strengths of the total number of PSDCHs received from a set PSDCH reception period; and transmitting the PSDCH, wherein if the sum of reception strengths of the total number of PSDCHs is greater than a previously set threshold value, then the PSDCH to be transmitted is transmitted under the transmission power controlled by the terminal, and if the sum of reception strengths of the total number of PSDCHs is less than a previously set threshold value, then the PSDCH to be transmitted can be transmitted under the maximum transmission power.

Abstract: The present invention discloses a method for reducing interference in a wireless communication system supporting D2D communication and an apparatus for the method. More specifically, in a wireless communication system supporting Device-to-Device (D2D) communication, a method for reducing interference in D2D communication comprises receiving, by a user equipment (UE), a D2D signal; determining, by the UE, whether interference is generated from resources in which the D2D signal has been transmitted; and in case it is determined that interference is generated from the resources in which the D2D signal has been transmitted, transmitting, by the UE, interference resource information for indicating that interference has been generated from the resources in which the D2D signal has been transmitted.
