Abstract:
1. An uplink feedback channel reporting method, comprising: periodically reporting regular information to a base station using a feedback channel, wherein the regular information comprises channel quality indicator (CQI) information, rank indicator information, or both CQI and rank indicator information, the CQI information further comprising average CQI comprising a single average CQI measure across selected multiple sub-bands, wherein obtaining the average CQI involves calculating a differential CQI between a previous frame and a current frame and between the current frame and a next frame; wherein if, during the periodic reporting of the CQI information to the base station, the average CQI is reported together with the differential CQI, then the reporting is done in the frequency domain; and if, during the periodic reporting of the CQI information to the base station, the average CQI is reported in a different time period than the differential CQI, then the reporting of a first differential CQI, reported right after the average CQI, comprises a frequency domain measurement, while the reporting of a subsequent differential CQI comprises a time domain measurement.
