Method and apparatus for transreceiving signal in wireless communication system
One embodiment of the present invention relates to a method for device-to-device transreceiving a signal by a first device in a wireless communication system, wherein the method for transreceiving a signal comprises the steps of: receiving from a second device a discovery signal; determining the number of antenna ports associated with the transmission of the discovery signal; and decoding the discovery signal based on the number of antenna ports, wherein an initial value of a sequence constituting the DMRS is determined by a parameter related to a cell ID, and the value of the parameter related to the cell ID is selected from a range of values differing from values available to a physical cell ID and a virtual cell ID.
