Summary:A method for transmitting a discovery message in a wireless communication system supporting device-to-device (D2D) direct communication, the method performed by the device, includes: discovering a D2D synchronization signal; classifying one or more macros by using the strength of the discovered D2D synchronization signal; receiving macro resource allocation information from a base station of the classified macro; sensing a macro resource of the classified macro based on the received macro resource allocation information; determining a macro resource for selecting a discovery resource through the sensing result; determining a discovery resource for transmitting a discovery message in the determined macro resource; and transmitting the discovery message through the determined discovery resource.
