Patent Images
1. A method of performing device-to-device communication by a terminal, the method comprising the steps of:
- receiving, at the terminal, information relating to the device-to-device communication from a base station, the information relating to the device-to-device communication including information relating to discovery signal resource configuration information and information for allocating a resource on discovery signal resource configuration information;
transmitting the discovery signal resource configuration information, from the terminal, to another terminal, which does not receive the information relating to the device-to-device communication from the base station, based on the information relating to the device-to-device communication; and
after the discovery signal resource configuration information is transmitted, transmitting, at the terminal, a discovery signal associated with information on the terminal to the another terminal, using at least one resource identified based on the discovery signal resource configuration information.

Abstract
Methods and apparatuses are provided for indicating a discovery signal resource by a User Equipment (UE) performing device-to-device communication. The UE receives information relating to the device-to-device communication from a base station. A synchronization signal including discovery signal-related information, is transmitted from the UE to a nearby UE, based on the information relating to the device-to-device communication. A discovery is performed based on the discovery signal-related information.
