Abstract

Dans un système de communication radio, chacun des terminaux utilisateur, tout en transmettant un signal de données à une station de base en utilisant différentes fréquences de bande de transmission de données qui sont affectées par une station de base, exécute un multiplexage temporel dun signal pilote avec le signal de données et transmet le signal résultant à la station de base. Une unité de gestion des ressources de la station de base détermine des bandes de transmission pilotes pour chaque terminal utilisateur de manière que la bande de transmission pilote couvre la bande de transmission de données pour chaque terminal utilisateur par le décalage de la fréquence, et indique au terminal utilisateur de transmettre des signaux pilotes au moyen des fréquences de bande de transmission déterminées. Ainsi, la station de base peut estimer un canal pour chaque fréquence de la bande de transmission de données à laide du signal pilote.
