<p>Provided are a method and an apparatus for transmitting a discovery signal for device-to-device (D2D) communications in a wireless communications system. The method includes: a step of allocating a time-frequency resource for the transmission of a D2D discovery signal; a step of generating the D2D discovery signal based on the allocated resource; and a step of transmitting the D2D discovery signal to a D2D receiving terminal. A random sequence used for allocating the time-frequency resource for the transmission of the D2D discovery signal is generated by using one of the UE identity of the D2D transmission terminal, a system frame number (SFN), an index (n_(D2D_DS)) for the D2D discovery index as an initial value.</p> |
