Abstract: A communications device and method of communicating using a communications device via a wireless access interface. The method includes transmitting signals representing data in accordance with a device-to-device communication protocol via a shared communication channel of the wireless access interface. The transmitting the signals includes: selecting an identifier which identifies a party and identifies a discovery communication type; transmitting a scheduling assignment message in an scheduling assignment portion of the shared communications channel, wherein the scheduling assignment message includes the selected identifier for discovery by one or more other communications devices; and transmitting the signals representing the data in a data portion of the shared communications channel in accordance with the scheduling assignment message. The method can facilitate use of discovery in device-to-device environments.
