Title (EN) METHOD AND SYSTEM FOR WIRELESS COMMUNICATION NETWORKS USING COOPERATIVE RELAYING
(FR) PROCEDE ET SYSTEME POUR DES RESEAUX DE COMMUNICATION SANS FIL UTILISANT LES RELAIS DE COOPERATION
Abstract: front page image
(EN)The present invention relates to relay supported wireless communication to enhance communication performance. In the wireless communication system according to the invention neighboring relay stations are arranged with substantially overlapping coverage. In the method according to the invention mobile stations makes soft association to relay stations. The mobile stations feed back the selection of relay stations and channel quality measures to the base station. The base station adapts the transmission to the relay stations based on each mobile stations reported soft associations and channel quality measures. In this way the control signaling to and from the relay stations can be very limited.
(FR)La présente invention concerne les communications sans fil supportées par des relais pour améliorer les performances de communication. Dans le système de communication sans fil selon la présente invention, des stations relais voisines sont disposées de manière à présenter une couverture considérablement chevauchante. Dans le procédé selon la présente invention, des stations mobiles font une association provisoire avec des stations relais. Les stations mobiles renvoient la sélection de stations relais et les mesures de qualité de voie à la station de base. La station de base adapte la transmission aux stations relais sur la base des associations provisoires et mesures de qualité de voie rapportées pour chaque station mobile. De cette manière, la signalisation de commande vers les stations de relais et en provenance desdites stations peut être très limitée.
