One embodiment of the present invention discloses a method by which a terminal receives a device-to-device (D2D) signal in a wireless communication system, the D2D signal receiving method comprising the steps of: receiving a subframe; receiving a first reference signal in a preset symbol of the subframe; and receiving reference signal pattern information in a symbol neighboring the preset symbol on the basis of the received reference signal, wherein if the reference signal pattern information indicates the transmission of a second reference signal, the terminal performs a linear interpolation during a channel estimation for a D2D signal demodulation in the subframe.
