A periodic report of channel quality information is transmitted to a receiving entity within a communication system. A UE transmits first channel quality information reports reporting an average of channel qualities for resource blocks at a first reporting frequency and a second channel quality information report for a preferred subset of resource blocks. The second channel quality information report is transmitted between the first channel quality information reports. A plurality of second channel quality information reports for the preferred subset of resource blocks are transmitted at a second reporting frequency. The first reporting frequency is different from the second reporting frequency.
