According to one embodiment of the present invention, a method of transmitting a D2D (device-to-device) signal, which is transmitted by a user equipment in a wireless communication system, comprising the steps of determining a sequence group, determining a base sequence in the sequence group, generating a reference signal sequence by applying cyclic shift to the base sequence, generating a demodulation reference signal sequence from the reference signal sequence and transmitting a subframe to which the demodulation reference signal sequence is mapped, wherein ID information, which is used for at least one selected from the group consisting of determination of the sequence group, determination of the base sequence and application of the cyclic shift, corresponds to one of an SSID (synchronization ID) and an L1 ID (layer 1 ID) changing according to time. |
