1. A device to device (D2D) communication method comprising:
- generating a connection identification (CID) for D2D communication using an identification (ID) of a specific terminal;
selecting a sequence corresponding to the CID; and
transmitting the selected sequence using a paging request resource including a plurality of subcarriers.

Abstract
Disclosed is a device to device (D2D) communication method. The D2D communication method includes generating a connection identification (CID) for D2D communication using an identification (ID) of a specific terminal, selecting a sequence corresponding to the CID, and transmitting the selected sequence using a paging request resource including a plurality of subcarriers. Accordingly, even in a channel selective wireless environment, a performance of a wireless link may be improved, and usage efficiency of wireless resources may be improved.

7. A D2D communication method which is performed in a transmission terminal requesting D2D communication connection, the D2D communication method comprising:
-
transmitting a request to send (RTS) signal by mapping a sequence corresponding to a generated CID in an RTS resource including a plurality of subcarriers; determining whether a transmission abandonment condition is satisfied based on a clear to send (CTS) signal received from a reception terminal; and transmitting a pilot signal when the transmission abandonment condition is satisfied. - View Dependent Claims (8, 9, 10)
