Based upon the use of the frequency band during the sensing block, a probability of non-interfering is calculated during a plurality of time periods in a subsequent inter-sensing block. The probability of non-interfering is used by the transceiver to determine a transmit power level such that the possibility of interference with licensed use on the frequency band is reduced.
