Abstract

Dans un système de radiocommunication, chacun des terminaux d'utilisateur, ensemble avec la transmission de signaux de données à une station de base au moyen de différentes bandes de fréquences de transmission de données assignées par une station de base, effectuent un multiplexage par temps d'ondes pilotes avec le signal de données et transmettent le signal qui en résulte à la station de base. Une unité de gestion des ressources de la station de base décide des bandes de transmission des ondes pilotes pour chaque terminal d'utilisateur, de sorte que la bande de transmission des ondes pilotes couvre les bandes de transmission de données pour chaque terminal d'utilisateur par décalage de fréquence, et indique au terminal d'utilisateur de transmettre les ondes pilotes au moyen des bandes de fréquence de transmission des ondes pilotes déterminées. La station de base peut ainsi estimer le canal pour chaque fréquence de bande de transmission de données au moyen des ondes pilotes.
