Abstract:
Provided is a power control method, etc., in cognitive radio communication, by which power control can be effectively performed without a large indirect cost. In the power control method, a target value of SNR is estimated on the basis of the control information relating to interference. Subsequently, communication power used for the cognitive radio communication is adjusted on the basis of the estimated target value of SNR. Thereby, power control can be effectively performed without a large indirect cost.
