Method for electricity measurement for V2V communications in wireless communication system, and device for same

A device communicating for vehicle-to-everything (V2X) communication, the device comprising:

• a transceiver;
• and
• a processor configured to:
• map a synchronization signal to a subframe and a demodulation reference signal (DMRS) associated with a physical sidelink broadcast channel (PSBCH) to the subframe for the V2X communication;
• and
• control the transceiver to transmit the synchronization signal and the DMRS to a receiving end,
• wherein the DMRS is mapped to three symbols in the subframe,
• wherein a sequence of the DMRS uses a first orthogonal cover code (OCC) corresponding to [1 1 1] when an identifier of the synchronization signal is even,
• wherein the sequence of the DMRS uses a second OCC corresponding to a phase shifted code of the first OCC when the identifier of the synchronization signal is odd, and
• wherein a cyclic shift parameter of the DMRS uses the identifier of the synchronization signal divided by 2.
