1. A cellular-telephone base station comprising:

  • A) a base-station receiver for monitoring reverse-channel signals in a plurality of reverse radio channels respectively associated with different forward radio channels;

    B) a forward-power circuit responsive to the base-station receiver for determining, for each of the forward radio channels, a forward power level as a function of the power of the reverse-channel signals that the base-station receiver monitors in the reverse radio channel associated with that forward radio channel and as a function of an average of a plurality of attenuation values of the plurality of reverse radio channels; and

    C) a base-station transmitter including a common power amplifier that generates a plurality of forward-channel signals by amplifying a composite signal comprising composite-signal components whose amplification by the common amplifier results in respective ones of the plurality of forward-channel signals, said base station transmitter responsive to the forward-power circuit, for simultaneously transmitting said plurality of respective forward-channel signals in the forward radio channels at the forward power levels respectively determined therefor by the forward-power circuit.
