CA 2447572

In a wireless digital communication system which may employ CDMA technology, a method (50) and system for obtaining channel quality (CQ) measurements for downlink resource allocation wherein a User Equipment (UE) (12) continuously measures RSCP (step) based on a communication on a reference channel provided by the network. The UE (12) measures timeslot ISCP (step 56) either continuously, by configuration or by rotation and reports downlink CQ (step 58). The UE (12) may report the RSCP once and the ISCP per timeslot, or may report some function of the RSCP/ISCP ratio such as modulation parameters or combined coding of all timeslots.

Dans un système de communication numérique hertzienne qui peut faire intervenir la technologie AMCR, un procédé et un système servent à obtenir des mesures de qualité de canal (CQ) pour une attribution de ressources de liaison descendante, un équipement utilisateur (UE) mesurant en continu la RSCP (puissance de code de signal reçu) en se basant sur une communication sur un canal de référence du réseau. L'UE mesure l'ISCP (puissance de code de signal d'interférence) par intervalle de temps, soit en continu par configuration, soit par rotation et reporte la CQ de liaison descendante. L'UE peut reporter la RSCP une fois et l'ISCP par intervalle de temps, ou peut reporter certaines fonctions du rapport RSCP/ISCP telles que des paramètres de modulation ou le codage combiné de tous les intervalles de temps.
