Abstract: The present invention relates to methods for efficiently relaying device to device (D2D) data utilizing a relay terminal (rUE) in a wireless access system supporting D2D communication, and apparatuses for supporting the methods. As one example of the present invention, a method for relaying D2D data by a relay terminal in a wireless access system supporting D2D communication may comprise the steps of: receiving a scheduling allocation (SA) signal for allocating a resource area where the D2D data are transmitted; receiving at least one D2D data; and relaying, from among the at least one D2D data, only the first D2D data received from a terminal out of coverage. The first D2D data among the at least one D2D data can be detected on the basis of a SA signal and a medium access control header relating to the at least one D2D data.
