Abstract:
A method for determining a forward data rate and a forward transmission power level in an access terminal of a mobile communication system, comprising the steps of:measuring a received carrier-to-interference ratio (C/I) of a forward pilot channel and selecting a largest one of C/I thresholds that is smaller than the measured C/I, stored in a C/I table, as a reference C/I; determining a data rate associated with the selected reference C/I; determining margin information for determining a forward transmission power level by calculating a difference between the measured C/I and the reference C/I if the measured C/I is not identical to the reference C/I; and transmitting the determined forward data rate and margin information over a reverse transmission channel; wherein the step of transmitting the determined forward data rate and margin information comprises the step of transmitting the determined forward data rate for one slot and the margin information for a next one slot over the reverse transmission channel.
