Abstract:
A method for controlling the power in a wireless communication system, the method comprising the steps of:determining a target value of a signal quality parameter to achieve a required signal quality for a full information rate frame of data of a received signal; determining a target value of the signal quality parameter for a fractional information rate frame of the received signal as a proportional adjustment to the full-rate target value, the proportional adjustment being a function of a fraction the fractional information rate frame bears to the full information rate; adjusting the fractional-rate target value by a variable power control scaling factor, wherein the variable power control scaling factor represents a fraction by which the fractional-rate target value can be reduced while maintaining the required signal quality for the frame; and evaluating a received value of the signal quality parameter for ones of power control groups in frames transmitted at the fractional information rate against the adjusted fractional-rate target value.
