1. An apparatus for direct device-to-device communication using an uplink carrier frequency and a downlink carrier frequency, the apparatus comprising:

  • a frequency synthesizer configured to provide the uplink carrier frequency and the downlink carrier frequency to both an up-converter and a down-converter;

    a transmission circuit comprising the up-converter and configured to generate a cellular uplink signal when the up-converter receives the uplink carrier frequency, and configured to generate a first device-to-device signal when the up-converter receives the downlink carrier frequency; and

    a reception circuit comprising the down-converter and configured to receive a second device-to-device signal when the down-converter receives the uplink carrier frequency, and configured to receive a cellular downlink signal when the down-converter receives the downlink carrier frequency.
