Patent ID: 7877106

Claim:
A mobile station adapted 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 mobile station being further adapted to participate in wireless P2P (peer-to-peer) communications by communicating directly with another mobile station using signals in form similar to the cellular communications signals and using said cellular spectral resource, wherein the cellular communications signals are CDMA (code division multiple access) signals or OFDM (orthogonal frequency division multiplexing) signals; wherein said cellular spectral resource comprises a downlink PMP band, and an uplink PMP band, wherein the mobile station is adapted to participate in wireless PMP (point to multi-point) communications using the downlink PMP band for receiving and using the uplink PMP band for transmitting, the mobile station being further adapted to participate in wireless P2P (peer-to-peer) communications using the PMP uplink band for both transmitting and receiving in a TDD (time division duplex) manner.
