ABSTRACT:
In a cellular-communications base station (10), an attenuation circuit 22 sets different power levels for different ones of the forward communications channels by which the base station transmits to the mobile units (12) that it services. From the reverse-channel transmit power that a reverse-channel-power circuit 52 derives from the associated reverse-channel power that the base station receives, a forward power circuit (58) infers the level of forward-channel transmit power that will result in the mobile unit's receipt of the requisite forward-channel power. In this way, the base station (10) avoids the need to transmit full power into all of the forward channels even if it is operating in accordance with a protocol that does not explicitly inform it of the forward-channel power that the mobile unit (12) is receiving.
