Calibration factor determining device, calibration factor determining method, device and method for CQI feedback using the same

摘要

A method in which a terminal interlocked with a calibration factor determination device feeds back CQI for a channel to a base station.It receives a calibration factor for a channel used by the terminal from the calibration factor determination device, and the current CQI for the channel based on the received calibration factor. After confirming, the current CQI for the current channel is fed back to the base station. The next CQI for the next channel after the current channel is predicted, the difference between the predicted CQI and the current CQI is calculated, and the calculated difference value is fed back to the base station as a CQI for the next channel.
