Abstract

A power transmission control apparatus for a CDMA system is disclosed which determines, with each of signals received from a plurality of mobile terminals, a difference between a power ratio to a total interference power to a requested power ratio, and controls the transmission power of the individual terminal on the basis of the above difference. The difference is weighted in accordance with communication quality required of the individual received signal so as to produce an evaluation value. The transmission power requested of the individual mobile terminal is updated such that the evaluation value decreases. Even when the number of calls increases and aggravates the difference of the signal weighted little, the evaluation value associated with such a signal varies little. At the same time, the signal weighted much can maintain the existing communication quality. When the difference of the signal weighted much increases, the evaluation value varies noticeably and allows the transmission power to be varied accordingly. It follows that the transmission power associated with the signal weighted much can be controlled adequately and rapidly.
