1. A wireless communication device operable to participate in wireless PMP (point-to-multi-point) communications by communicating directly with a cellular base station using cellular communications signals transmitted on a cellular spectral resource, the wireless communication device being further operable to participate in wireless P2P (peer-to-peer) communications by communicating directly with another wireless communication device using signals similar in form to the cellular communications signals and using said cellular spectral resource;

  • wherein said cellular spectral resource comprises a downlink PMP band, and an uplink PMP band, wherein the wireless communication device is operable to participate in the wireless PMP communications using the downlink PMP band for receiving and using the uplink PMP band for transmitting, the wireless communication device being further operable to participate in the wireless P2P communications using the uplink PMP band for both transmitting and receiving the wireless P2P communications.
