Channel quality indicator for time, frequency and spatial channel in terrestrial radio access network
First Claim
1. A method in a wireless communication device capable of communicating on a channel comprising a plurality of sub-carriers divided into a plurality of frequency bands, wherein each frequency band includes at least one sub-carrier, the method comprising:
- measuring a channel quality indicator for a plurality of frequency bands;
identifying a subset of frequency bands for which the channel quality indicator has been measured based on a subset criterion;
sending information identifying at least one of the subset of frequency bands for which the channel quality indicator has been measured or frequency bands not in the subset of frequency bands for which the channel quality indicator has been measured, and sending a subset channel quality indicator value associated with at least the subset of frequency bands.

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 (310) a channel quality indicator (CQI) for a plurality of frequency bands, identifies (320) a subset of frequency bands for which the channel quality indicator has been measured based on a subset criterion, and transmits (330) 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.
