Patent ID: 7526255

Claim:
A method for coordinating radio resource usage by a plurality of wireless devices in an unlicensed frequency band, the method comprising: providing a set of operating parameters, the operating parameters comprising a transmission power (P), a spectrum occupation time (T), and a spectrum access probability (R) for restricting the access of the spectrum by the plurality of radio frequency devices, the set of operating parameters including values assigned to the operating parameters and used to determine transmission decisions to access the unlicensed frequency band for a transmitter; providing a receiver transmitter feedback mechanism for governing the operating parameters; determining feedback information from a receiver receiving a transmission from the transmitter; and calculating a feedback value based on the feedback information, the feedback value used to alter values for the set of operating parameters, wherein the altered values for the set of operating parameters are used to determine transmission decisions for the transmitter to access the unlicensed frequency band based on the transmission power (P), the spectrum occupation time (T), and the spectrum access probability (R).
