Abstract
A method (400) and apparatus (501) provide for rapid power control based on a quality related value, e.g. channel quality indicator (CQI) value. A transmit power level can be derived from a CQI value received according to a time period, e.g. corresponding to 500 Hz. A first predicted value can be predicted based on the CQI value, at a first time within the time period and a power adjustment value can be determined based on the CQI value as well as the first predicted value at a rate that exceeds the rate of receiving the CQI values. Note that other predicted values for or corresponding to the CQI value can be predicted at other times within the time period and that power adjustment values can be determined through interpolation between predicted values for any time within the period.
