In the present invention, a method for performing a handover during a device-to-device communication in a wireless access system, and a device for same are disclosed. More particularly, the method comprises the steps of: a first device sensing a handover state by considering a link quality with a second device while performing device-to-device communication with the second device; the first device measuring channel quality with respect to neighboring devices by using a reference signal that is transmitted from the neighboring devices; the first device transmitting a handover request message to a relay device, which is selected from the neighboring devices by means of a measurement result with respect to the channel quality, for starting the handover to the relay device that is selected; the first device receiving from the relay device a handover completion message indicating the completion of resource allocation; and the first device performing the device-to-device communication with the second device by using a resource that is allocated by the relay device. |
