Efficient relay transmission method and device in wireless access system supporting device to device communication
The present invention relates to a method for efficiently transmitting and receiving a device to device (D2D) signal by utilizing relay user equipment (rUE) in a wireless access system supporting D2D communication. As one embodiment of the present invention, a method by which rUE efficiently relays a D2D signal in a wireless access system supporting D2D communication can comprises the steps of: receiving, from a base station, an upper layer signal including a reference value for measuring signal quality; measuring signal quality for at least one access link; selecting an access link to be relayed on the basis of the reference value; and relaying a D2D signal for the selected access link.
