Abstract
Disclosed is a method for transmitting a discovery signal in device-to-device communication. In phase 1, for devices at a long range, a discovery signal is transmitted by dividing a band like in OFDMA, and in phase 2, for devices at a short range, the discovery signal is transmitted by using a full band.
