Patent ID: 7548758

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; a transmitter for transmitting PMP communications and P2P communications on the uplink PMP band; a first receiver for receiving PMP communications on the downlink PMP band; a second receiver for receiving P2P communications on the uplink PMP band, adapted to listen to PMP communications from the network on the downlink PMP band with the first receiver for maintenance purposes while transmitting P2P communications and while receiving P2P communications with the second receiver.
