Patent ID: 7477658

Claim:
A method, comprising: estimating a change in a required signal-to-interference with respect to a change from a first data rate to a second data rate, wherein the first data rate is applied to a dedicated channel during a first transmission time interval transmitted prior to a second transmission time interval; adjusting a target signal-to-interference to match the second data rate applied during the second transmission time interval of the dedicated channel, wherein the target signal-to-interference is configured to provide a reference signal-to-interference value for closed-loop power control; adjusting the target signal-to-interference by using the change in the required signal-to-interference and a target signal-to-interference that matches the first data rate; and performing a comparison between a signal-to-interference measured from the dedicated channel transmitted at the second data rate and the target signal-to-interference, wherein a transmit power control command is provided to a transmitter according to the comparison.
