<p>The present specification relates to a method and an apparatus for transmitting a synchronization signal for device to device communications in a wireless communication system. According to the present specification, the method for transmitting the synchronization signal in a synchronizing source of device to device (D2D) comprises the steps of: creating a sequence for a primary device to device synchronization signal (PD2DSS); mapping the created sequence in a time-frequency resource space; and transmitting a device to device synchronization signal (D2DSS) including the mapped sequence to a terminal, wherein the sequence is created based on any one among six root indexes, and a remainder obtained by dividing each root index into seven for the six root indexes is four, one, six, two, three, and five, respectively.</p> |
