| 1. A method for communicating between at least one base station and at least one mobile device, comprising:
transmitting, from the base station, a pilot signal having at least one transmitted characteristic over a forward link channel;
receiving, at the base station, a data rate control signal transmitted by the mobile device, the data rate control signal
indicating a data rate in a first range of data transmission rates, the data rate control signal being based on a characteristic
of the forward link channel within a second preselected bandwidth;
scaling, at the base station, the received data rate control signal by a scale factor so that the scaled received data control
signal indicates a data rate in a second range of data transmission rates, wherein scaling the received data rate control
signal comprises expanding the data rates indicated in the scaled received data rate control signal based on a coefficient
related to a ratio of a first preselected bandwidth and the second preselected bandwidth; and
determining a transmission rate in the second range of data transmission rates based on the scaled data rate control signal.
