摘要：The present invention provides a method of estimating a channel quality of awireless data transmission channel on the basis of channel quality indicators. By means ofestimating the channel quality an accurate and momentary channel quality of a data
transmission channel can be obtained on the basis of non-momentary CQIs that may besubject to measurement inaccuracies, delay or that may feature unacceptable quality dueto e.g. high velocity movement of a mobile station. The invention provides determinationof the quality and reliability of an obtained channel quality indicator and to select and tosuccessively apply one or a plurality of various estimation procedures in order todetermine an accurate and momentary channel quality indicator. Moreover, by makinguse of an iterative calibration procedure a CQI is determined such that a systematic offsetbetween a defined transmission quality measure and an actually measured transmissionquality can be effectively eliminated.
