Abstract
In a mobile communication system comprising at least two base stations coupled to a common base station controller, each base station with which a particular mobile station is communicating sends its received frame quality message to the common base station controller. The base station controller combines the received messages to provide an improved estimate of the correct message and thus a correct power level for the forward link signal. Each base station preferably responds independently to error messages it receives from the mobile station and also sends the error message to the base station controller. After receiving power control commands from the base station controller, the base station then determines whether it responded properly at the time when it received the error message from the mobile station.
