The present specification relates to: a method for efficiently indicating, by a base station, a resource region in which control information and data are to be transmitted to a transmission terminal, in a wireless communication system supporting device to device (D2D) communication; and an apparatus therefor. To this end, the transmission terminal receives resource allocation information relating to D2D communication from the base station, and transmits, to the receiving terminal, control information (SA) for D2D communication and data corresponding to the control information on the basis of the resource allocation information received from the base station, wherein the resource allocation information includes information indicating a plurality of frequency resource points, and the transmission terminal defines the SA transmission resource region and the data transmission resource region according to a predetermined rule by using the plurality of frequency resource points.
