1. A Wide-band Code Division Multiple Access (“

  • WCDMA”

    ) system comprising a base station and a mobile station;

    a channel including a baseband signal having a variable transmission rate and including a pilot channel coupling the base station and the mobile station;

    means responsive to the baseband signal for predicting future power attenuation on the channels based on computing a long range power prediction of each finger of a rake receiver; and

    means responsive to the channel prediction means to signal both the transmitter and receiver over the pilot channel to reconfigure the transmission rate according to the predicted power attenuation.
