| 摘要 |
<p>The present invention relates to a device-to-device (D2D) discovery method to provide a D2D proximity service through a device-to-device communications in a 3GPP LTE/LTE-A system and, more specifically, to a method for a terminal to transmit a discovery signal which comprises: a step of receiving channel allocation information to transmit a discovery signal from a base station; a step of generating a discovery signal based on the channel allocation information, wherein the discovery signal is to be transmitted to a D2D terminal adjacent to the terminal; and a step of transmitting the generated discovery signal based on the channel allocation information.</p> |
