Abstract

L'invention concerne un procédé d'attribution d'une ressource dans un équipement utilisateur (100), consistant à : recevoir un message de mode (603 703) à partir d'une station de base (200), le message de mode (603, 703) comprenant des informations d'une qualité pour prendre en compte une configuration de la ressource pour attribuer la ressource, recevoir un message d'attribution souhaité (604 704) à partir de la station de base (200), le message d'attribution souhaité comprenant des informations concernant l'attribution souhaitée de la ressource et déterminer l'attribution finale (601''', 701''') de la ressource sur la base des informations concernant l'attribution souhaitée de la ressource et de la configuration de la ressource (602, 702) combinée à la qualité pour prendre en compte la configuration de la ressource pour attribuer la nouvelle ressource.
