Title:
METHOD FOR GENERATING A CHANNEL QUALITY INDICATOR BY BIASING SIGNAL-TO-INTERFERENCE RATIO
Document Type and Number:
WIPO Patent Application WO2005006568
Kind Code:
A3
Abstract:
A method for biasing signal-to-interference ratio (SIR) to generate channel quality indicator (CQI) includes measuring the packet error rate (PER) of a received signal and comparing the PER to a to the target PER to generate a correction term. The correction term is combined with the SIR estimation of a reference channel to generate a CQI. The CQI is reported to a transmitter to adjust signal configurations, such as code rate, modulation type, number of codes, power offset.
