Communication scheme for channel quality information
A user equipment (UE) includes a processor to determine channel quality information and a transmitter, coupled to the processor, that transmits first channel quality information reports reporting channel quality information determined for resource blocks at a first reporting frequency. The transmitter also transmits second channel quality information reports reporting channel quality information determined for a subset of resource blocks between transmission of the first channel quality information reports. A plurality of second channel quality information reports for the subset of resource blocks are transmitted at a second reporting frequency different from the second reporting frequency.
