Abstract
A communication control device including an acquisition unit configured to acquire radio resource information indicating a radio resource, the radio resource being a unit time of cellular communication, for transmitting a discovery signal enabling another device to discover a device conducting device-to-device communication, and a control unit configured to control transmission of the radio resource information to a terminal device. The control device makes it possible to moderate load for a device conducting device-to-device communication (D2D communication).
Claims10
A terminal device comprising:
- a radio transceiver;
- and
- circuitry configured to:
- detect, via the radio transceiver, a discovery signal at periodic detection times separated by a first period of time in a case where the terminal device is in coverage, the discovery signal being used for Device-to-Device (D2D) discovery;
- and
- detect, via the radio transceiver, the discovery signal at periodic detection times separated by a second period of time longer than the first period of time in a case where the terminal device is out of coverage.
A method for a terminal device, the method comprising:
- detecting, via a radio transceiver equipped with the terminal device, a discovery signal at periodic detection times separated by a first period of time in a case where the terminal device is in coverage, the discovery signal being used for Device-to-Device (D2D) discovery;
- and
- detecting, via the radio transceiver, the discovery signal at periodic detection times separated by a second period of time longer than the first period of time in a case where the terminal device is out of coverage.
