Patent ID: 8493874

Claim:
A method for providing channel quality feedback in an Orthogonal Frequency Division Multiplexing communication system wherein a frequency bandwidth is divided into a plurality of sub-bands, the method comprising: measuring, by a mobile station, a channel quality metric associated with each sub-band of a plurality of sub-bands of the frequency bandwidth; determining a mean channel quality metric value based on the measured channel quality metrics; determining a channel quality metric second order statistic value based on the measured channel quality metrics, wherein the channel quality metric second order statistic value comprises one or more of a channel quality metric standard deviation and a channel quality metric variance; maintaining a mapping of a plurality of channel quality values, wherein each channel quality value of the plurality of channel quality values is mapped to a range of mean channel quality metric values and a range of channel quality metric second order statistic values; determining a channel quality value of the plurality of channel quality values based on the determined mean channel quality metric value, the determined channel quality metric second order statistic value, and the mapping of the plurality of channel quality values; and reporting the determined channel quality value to a radio access network.
