A method and system for controlling the transmission power of at least one downlink (DL) enhanced uplink (EU) signaling channel such that enhanced dedicated channel (E-DCH) DL signaling is delivered efficiently and reliably. The system includes at least one wireless transmit/receive unit (WTRU), at least one Node-B and a radio network controller (RNC). At least one of the WTRU and the Node-B compute EU transmission failure statistics on the DL EU signaling channel and report the EU transmission failure statistics to the RNC. The RNC then adjusts a transmission power offset of the DL EU signaling channel to be used in determining transmission power level of the DL EU signaling channel at the Node-B based on the EU transmission failure statistics.
La présente invention concerne un procédé et un système de commande de la puissance de transmission d'au moins un canal de signalisation de voie descendante (DL) voie montante avancée (EU) de sorte que la signalisation DL de canal spécialisé avancé (E-DCH) soit apportée de manière efficace et fiable. Le système comprend au moins une unité d'émission/réception sans fil (WTRU), au moins un Noeud B et un contrôleur de réseau de radiocommunication (RNC). Au moins une des entités telles que la WTRU et le Noeud B calculent des statistiques d'échecs de transmission sur le canal de signalisation DL EU et envoient au RNC un rapport portant sur les statistiques d'échecs de transmission EU. Le RNC ajuste ensuite un décalage de puissance de transmission du canal de signalisation DL EU devant être utilisé pour déterminer le niveau de puissance de transmission du canal de signalisation DL EU au niveau du Noeud B sur la base des statiques d'échecs de transmission EU.
