PROBLEM TO BE SOLVED: To provide a transmission power control method capable of attaining a desired reception quality while preventing increase in average transmission power even if a propagation path gain fluctuation in relatively short cycle occurs. SOLUTION: A transmission power is so controlled that a propagation path gain increases a communication path capacity as the transmission power for fluctuation. In other words, the transmission power is determined so that the sum of a noise power reduced to a transmission end (= reception noise power/propagation path gain) and a transmission power is constant. As a result, contrary to a conventional manner, the transmission power is so controlled that it is reduced when the propagation path gain drops while it is increased when the propagation path gain increases.
