System and method for peer-to-peer communication in cellular systems
First Claim
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.

Abstract
Systems and methods are provided for delivering both PMP communications, for example standard cellular communications via a base station, and also delivering P2P communications, for example, communications between two mobile stations, using the same spectral resources for both types of communication.

16. A network element for a wireless communications network, comprising:
-
a receiver operable to receive signals from the wireless communications network; a controller operable to determine from the received signals when a pair of wireless communication devices which are communicating with each other via a cellular spectral resource of the wireless communications network are sufficiently close for P2P (peer-to-peer) communications; and a transmitter, responsive to such determination, operable to send at least one signal to said pair of wireless communication devices to direct said pair of wireless communication devices to start communicating directly with one another using P2P communications; wherein said cellular spectral resource comprises a downlink PMP (point to multi-point) band, and an uplink PMP band, wherein the pair of wireless communication devices are operable to participate in wireless PMP communications using the downlink PMP band for receiving and using the uplink PMP band for transmitting, the pair of wireless communication devices being further operable to participate in wireless P2P communications using the uplink PMP band for both transmitting and receiving the wireless P2P communications. - View Dependent Claims (17, 18, 19)
