COMMUNICATION SCHEME FOR CHANNEL QUALITY INFORMATION
First Claim
1. A transmitter for transmitting a periodic report of channel quality information to a receiving entity within a communication system, the transmitter comprising:
- a transmitting unit configured to transmit first channel quality information reports reporting an average of channel qualities for resource blocks at a first reporting frequency, and to transmit a second channel quality information report for a preferred subset of resource blocks,wherein the transmitter is configured to transmit the second channel quality information report between the first channel quality information reports.

Abstract
The invention relates to a method for transmitting and a method for reconstructing channel quality information in a communication system. Further, the invention also provides a transmitter and receiver performing these methods, respectively. The invention suggests a scheme for communicating channel quality measures that on the one hand allows for an accurate reconstruction of the channel quality measures at the receiver and on the other hand requires an acceptable transmission overhead. This is achieved by partitioning channel quality measures into at least two partitions and to compress the values partition-wise, for example, by means of a discrete cosine transform and the transmission of only a subset of the resulting coefficients.
