1. A signal transmission/reception method of a device in a mobile communication system, the method comprising:
transmitting, by the device, a device to device (D2D) request signal to a base station, wherein the D2D request signal includes at least one of device information, paired neighbor device information, pairing connection information, pairing resource information, and device buffer size; receiving, by the device, information associated with a discovery signal and information associated with a pairing signal from the base station, wherein the information associated with the discovery signal and the information associated with the pairing signal includes an identification of a resource region to use when transmitting or receiving the discovery signal and the pairing signal based on the D2D request; determining, by the device, a resource to receive the pairing signal for the device; transmitting, by the device, the discovery signal including information related to the determined resource to receive the pairing signal for the device within a first period; receiving, by the device, from a neighbor device that received the discovery signal, the pairing signal within a second period using a resource determined based on the information related to the determined resource to receive the pairing signal for the device; and communicating a data signal with the paired neighbor device during a third period, wherein the resource for transmitting the pairing signal for the device is selected based on at least one signal received by the neighbor device during the first period. |
