Abstract
Operating a user equipment in a mobile communication system includes generating a measure of reliability of a predicted channel estimate and of impairment stability, wherein the predicted channel estimate is a predicted estimate of a channel between the user equipment and a node of the mobile communications system. Transmission of a channel quality report to the node of the mobile communication system is controlled as a function of the generated measure of reliability of the predicted channel estimate and of impairment stability. Transmission control includes inhibiting transmission of the channel quality report to the node of the mobile communication system for a duration of time corresponding to the measure of reliability of the predicted channel estimate and of impairment stability.
