Patent ID: 8452317

Claim:
A method of operating a wireless communications device supporting peer to peer communications in a base station uplink frequency band, the method comprising: receiving a first signal from a base station in a downlink frequency band; performing an evaluation on the received signal to obtain information through both measuring a signal power of the first received signal and extracting encoded information conveyed in the first received signal wherein the transmission level of the first signal or the encoded information is varied by the base station to dynamically regulate interference to the base station uplink frequency band generated by a plurality of peer to peer wireless terminals; and controlling peer to peer transmission power for at least some peer to peer signal transmissions in said uplink frequency band as a function of the result of the evaluation of said first received signal, wherein controlling peer to peer transmission power includes using a first function that limits peer to peer transmission power to a lower level for a first received signal power level than for a second received signal power level which is higher than said first received signal power level.
