Abstract
A wireless communication terminal that communicates on a plurality of sub-carriers divided into a plurality of frequency bands, wherein each frequency band includes at least one sub-carrier. The terminal measures a channel quality indicator (CQI) for a plurality of frequency bands, identifies a subset of frequency bands for which the channel quality indicator has been measured based on a subset criterion, and transmits a report identifying a subset of frequency bands for which a channel quality indicator has been measured or frequency bands not in the subset. In some embodiments, the report also includes a subset CQI value associated with at least the subset of frequency bands identified.
