1. A relay node in a mobile telecommunications system including a base station and the relay node, the relay node comprising:
a transceiver; and
control circuitry configured to:
receive a relay request from a first terminal without receiving another relay request from a second terminal, the relay request requesting to relay communications between the first terminal and the second terminal;
identify a resource pool for terminal-to-terminal relaying;
forward the relay request received from the first terminal to the base station;
allocate, after forwarding the relay request and without receiving the another relay request, first resources from the resource pool for the first terminal to communicate via the relay node for device-to-device (D2D) communication with the second terminal;
allocate, after forwarding the relay request and without receiving the another relay request, second resources from the resource pool for the second terminal to communicate via the relay node for the D2D communication with the first terminal;
notify the first terminal of the allocated first resources;
notify the second terminal of the allocated second resources; and
relay messages, over the first and second resources, between the first terminal and the second terminal for the D2D communication.
