Abstract

L'invention concerne un appareil et un procédé d'affectation d'une ressource radio à l'aide d'un système de transmission localisée et d'un système de transmission distribuée combinés dans un système d'accès multiple par répartition orthogonale de la fréquence. La présente invention concerne un système d'affectation de ressources radio au moyen du système de transmission localisée et du système de transmission distribuée dans un système OFDM. De plus, la présente invention permet d'affecter des ressource radio à chaque terminal selon le système de transmission distribuée en fonction du type de trafic et de l'état de canal du terminal. La présente invention met en correspondance et affecte de multiples blocs de ressources virtuels distribués à des blocs de ressources physiques d'une dimension prédéterminée de façon dispersée, permettant ainsi à un terminal correspondant de maximiser le gain de diversité de fréquence pour les données transmises.
