Le procédé comprend les étapes suivantes : un équipement utilisateur reçoit un bloc d'informations maître (MIB) diffusé par un dispositif de réseau, le MIB comprenant des premières informations d'indication servant à indiquer des ressources temps-fréquence occupées par un ensemble de ressources de commande publiques ; l'équipement utilisateur décode l'ensemble de ressources de commande publiques sur les ressources temps-fréquence indiquées par les premières informations d'indication pour obtenir des secondes informations d'indication, les secondes informations d'indication étant utilisées pour indiquer des ressources temps-fréquence occupées par un ensemble de ressources de commande de niveau utilisateur ; l'équipement utilisateur reçoit des données de service sur des ressources temps-fréquence autres que l'ensemble de ressources de commande publiques et les ressources temps-fréquence occupées par l'ensemble de ressources de commande de niveau utilisateur dans des ressources temps-fréquence attribuées à l'équipement utilisateur. En utilisant les modes de réalisation de la présente invention, un multiplexage dynamique de ressources temps-fréquence peut être mis en œuvre.
