Abstract
A plurality of base station transceiver subsystems determine whether to scale the forward link transmission power level and, if so, by what amount to control forward link transmission power level mismatch. The plurality of base stations transmit reverse link signal-to-noise ratio information and forward link transmission power levels for a specified transmission to the base station controller. The base station controller compares the reverse link signal-to-noise ratio readings received from each of the plurality of base stations to determine and select a dominant base station. The base station controller then transmits the dominant base station's forward link transmission power level for the specified transmission to each of the plurality of base stations that is communicating with the mobile station that is in hand-off. Each base station, accordingly, determines whether to scale its forward link transmission power level.
