Scheduling method between terminals for search resource allocation in direct device to device communication and device thereof
First Claim
1. A method of allocating discovery resources of a terminal configured to perform device-to-device (D2D) communication comprising:
- transmitting a request signal including a contention index of the terminal on a wireless resource;
if a response signal is received on the wireless resource in response to the request signal, selecting a discovery resource corresponding to the contention index of the terminal based on the response signal; and
performing discovery for the D2D communication using the selected discovery resource.

Abstract
The present invention relates to a scheduling method between terminals for a search resource allocation in direct device to device communication and a device thereof. The present invention relates to, as a search resource allocation method of a terminal which performs device to device (D2D) communication, a proximity searching method and a device thereof, and the method comprises the steps of: transmitting and receiving a signal through a wireless resource determined so as to explicitly or implicitly transmit and receive a contention index of the terminal; selecting a search resource on the basis of a response signal when the response signal is received through the wireless resource; and performing a search for the D2D communication by using the selected search resource.
