A method and apparatus for controlling signal power in a communication system provides improved power control when changing the rate at which data is sent between a transmitter (2) and a receiver (4). When data arrives at the transmitter (2) for transmission at a high rate, power control feedback is changed from a slow mode (with a low bandwidth feedback channel) to a fast mode (with a high bandwidth feedback channel). This control changes even before the data is transmitted at the high rate. Once the power level is accurately estimated for data transmission at the high rate, the data transmission begins at the high rate. |
