    Abstract: A communications device includes a transmitter configured to transmit signals to one or more other communications devices via a wireless access interface, the one or more communications devices configured to perform device-to-device communications. A receiver is configured to receive signals from the one of the other communications devices via the wireless access interface, and a controller controls the transmitter and receiver to transmit or to receive the signals via the wireless access interface to transmit or to receive data represented by the signals. The wireless access interface provides a scheduling region including plural predetermined sections of communications resources, and plural sections of shared communications resources. Transmission of a scheduling assignment message in a section of the scheduling region informs other devices of a group that a communications device will transmit signals representing data in a corresponding section of the shared communications channel.

    Abstract: A communications system for device-to-device communications includes a group of plural communications devices, each configured to perform device-to-device communications via a wireless access interface with one or more other communications devices of the group. One of the communications devices is configured to detect interference in communications resources of the wireless access interface caused by signals transmitted by another communications device, and to provide, in response to detecting the interference, an indication of the interference to one or more of the communications device. By the communications device of the first group of communications devices detecting the interference and communicating an indication of the interference to the other members of the group, then members of the group can adapt the transmission and reception of data via the wireless access interface to avoid resources of the wireless access interface which is subject to interference.

    Abstract: A communications device acting as a relay device is configured to communicate with communications devices operating with a mobile communications network and infrastructure equipment. The relay device comprises transmitter circuitry, receiver circuitry and controller circuitry. The controller circuitry is configured to determine whether predetermined conditions relating to the setting of an indication bit have been met, wherein the indication bit indicates whether the relay device is able to form new connections with one or more of the communications devices, to set the indication bit dependent on the determination of whether the predetermined conditions have been met. The relay device is not able to form new connections with one or more of the communications devices when the predetermined conditions are met, and to broadcast the indication bit.

    Abstract: A communications device can identify one or more sections of plural predetermined sections, divided into time-units, of shared communications resources of a wireless access interface for transmitting data signals to one or more other communications device. The communications device detects whether another of the one or more communications devices are transmitting signals in one or more of the identified sections of the shared communications resources in at least one time divided unit, and if signals transmitted by another of the communications devices are not detected, the device transmits signals in the identified one or more predetermined sections of the shared communications resources for at least one of the time divided units, and then, after a collision avoidance time, detects for at least one subsequent time unit whether another of the one or more communications devices transmits signals in one or more of the identified sections of the shared communications resources.
