The present specification provides a method and an apparatus for transmitting a discovery signal for direct communications between terminals in a wireless communications system. The method includes the steps of: allocating time-frequency resources for transmitting a D2D detection signal; generating the D2D detection signal based on the allocated resources; and transmitting the D2D detection signal to a D2D reception terminal. A cyclic shift (CS) value for DM-RS included in the D2D detection signal is generated at random for each periodic transmission of the detection signal based on multiple parameters including parameters which may have different values for each periodic transmission of the detection signal. |
