<p>Provided are a method and an apparatus for transmitting a discovery signal for direct D2D communication in a wireless communication system. A method for transmitting a discovery signal, according to the present description, comprises the steps of: allocating time-frequency resources for D2D discovery signal transmission; generating a D2D discovery signal on the basis of the allocated resources; and transmitting the D2D discovery signal to a D2D receiving device, wherein a cyclic shift value, for DM-RS, comprised in the D2D discovery signal is randomly generated at every periodic transmission of the discovery signal on the basis of a plurality of parameters comprising a parameter which can have a different value at every periodic transmission of the discovery signal.</p> |
