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.
La présente invention concerne un procédé d'introduction d'un biais dans le rapport signal-brouillage (SIR) visant à générer un indicateur de qualité de voie (CQI). Ledit procédé consiste à mesurer le taux d'erreurs de paquets (PER) d'un signal reçu et à comparer le PER à un PER cible afin de générer un terme de correction. Le terme de correction est combiné à l'estimation du SIR d'une voie de référence aux fins de la génération d'un CQI. Le CQI est transmis à un émetteur aux fins de l'ajustement des configurations du signal, du type vitesse de codage, type de modulation, nombre de codes, décalage de puissance.
