A method of allocating resources for communications in a mobile telecommunication system wherein the mobile telecommunication system provides a wireless interface for a base station to communicate with communications devices and wherein a communications device is operable to transmit signals to another communications device using resources of the wireless interface and in accordance with a device-to-device communication protocol. A first pool of the resources is allocated to device-to-device communications of the broadcast type and a second pool of the resources is allocated to a device-to-device communications of the unicast type, the second pool of resources being separate from the first pool. The method comprises a first communications device transmitting broadcast messages using resources of the first resources pool and a second communications device transmitting unicast messages using resources of the second resources pool.
