Patent ID: 8150328

Claim:
A method for spectrum sensing management and control in a cognitive radio (CR) system with a CR base station and CR subscribers having sensors, comprising: obtaining a list of spectrum opportunities and predetermined operating parameters from a geo-location policy database; sending sensor control data to the sensors of the CR subscribers, the sensor control data including the list of spectrum opportunities and sensor configuration; sensing one or more spectrum opportunities from the list of spectrum opportunities at the CR subscribers based on the sensor control data received from the CR base station, the CR subscriber generating sensing feedback information in response thereto; sending the sensing feedback information back to the CR base station; combining the sensing results received in various sensing feedback information and comparing to the predetermined operating parameters obtained from the geo-location policy database; ranking the spectrum opportunities by the CR base station based on a multistage ranking technique thereby generating a ranked channel list and updated sensor control data; and transmitting the ranked channel list and updated sensor control data to the CR subscribers thereby providing sensor control and management.
