Abstract
A method to adapt channel quality indicator (CQI) reports from user equipment (UE) is provided. This involves first determining the presence of a high-speed shared control channel (HS-SCCH) signal. An estimated signal to noise ratio (SNR) is also determined. Next an SNR correction based on the presence or lack thereof of the HS-SCCH signal and the CRC checks for HS-SCCH and HS-DSCH signals are determined and applied to the estimated SNR. The CQI report is then generated based on the corrected estimated SNR. This CQI report which takes into account a corrected estimated SNR may then be used to adjust the HS-SCCH signal in an HSDPA telephony system.
