Method and device for transmitting and receiving D2D signal by relay terminal in wireless access system supporting device-to-device communication
Provided are methods for, in a wireless access system supporting device-to-device (D2D) communication, configuring a relay terminal and selecting a link through which the relay terminal can efficiently transmit a D2D signal, and devices for supporting same. A method for effectively transmitting a D2D signal by a relay terminal in a wireless access system supporting D2D communication, according to an embodiment of the present invention, comprises the steps of: receiving relay mode configuration information from a base station; receiving scheduling information about a first resource pool and a second resource pool from the base station; relaying a D2D signal through an access link in the first resource pool; and transmitting the D2D signal through a one-hop D2D link in the second resource pool. The relay terminal is connected to both of the access link and the one-hop D2D link, wherein the access link can be configured for D2D relay communication with the base station, and the one-hop D2D link can be configured for D2D direct communication with another terminal.
