    • The present invention relates to a method of performing direct communication between terminals, a method of supporting same, and an apparatus for same. A method for a base station to support device-to-device (D2D) communication in a wireless communication system supporting the D2D communication includes the steps of: receiving D2D link information including at least one piece of information on a reception signal strength or a signal to noise ratio (SNR) for a link between D2D terminals and information on a degree of interference by at least one other D2D terminal transmitting a transmission request signal from at least one D2D terminal receiving the transmission request signal which is a signal for requesting the D2D communication; and setting at least one D2D link between the receiving D2D terminals on the basis of the at least one piece of information on the reception signal strength or the signal to noise ratio (SNR) for the link between the D2D terminals and the information on the degree of interference, wherein the set D2D link information can include information on a D2D terminal pair for performing the D2D communication.
    • 本发明涉及一种在终端之间进行直接通信的方法,一种支持终端的方法及其装置。 一种用于在支持D2D通信的无线通信系统中支持设备到设备(D2D)通信的基站的方法包括以下步骤:接收包括至少一条关于接收信号强度或信号的信息的D2D链路信息 D2D终端之间的链路的信噪比(SNR)和由至少一个其它D2D终端的信息的信息的信息,所述至少一个D2D终端从接收作为请求D2D的信号的至少一个D2D终端发送发送请求信号 通讯; 并且根据关于D2D终端之间的链路的接收信号强度或信噪比(SNR)的信息和关于程度的信息的至少一条信息,在接收D2D终端之间设置至少一个D2D链路 的干扰,其中所述D2D链路信息可以包括关于用于执行D2D通信的D2D终端对的信息。

    • Disclosed are a method for simultaneously handing over devices which perform device-to-device communication to another cell in a wireless access system that supports device-to-device communication, and an apparatus for supporting the method. The method for simultaneously handing over devices in a wireless access system that supports direct device-to-device communication according to one embodiment of the present invention may comprise the following steps: detecting an occurrence of a handover condition in a first device that performs direct device-to-device communication; transmitting, to a second device that performs direct device-to-device communication, a cell state check request message for requesting information on a channel state with respect to a base station; searching for a target cell for handover by the first device; receiving, from the second device, a cell state check response message containing information on the channel state; searching for a common cell in which the target cell searched for by the first device and the target cell contained in the information on the channel state coincide with each other; and transmitting, to the second device, a common cell indication message for indicating the simultaneous handover of devices. Here, the common cell indication message may contain information on the common cell.
