Abstract
Des aspects de la présente invention peuvent comprendre, par exemple, la réception, par un élément réseau d'un système d'antennes distribué, d'un signal de référence, d'un canal de commande et d'un premier signal modulé à une première fréquence porteuse, le premier signal modulé contenant de premières données de communication fournies par une station de base et adressées à un dispositif de communication mobile. Les instructions dans le canal de commande commandent à l'élément réseau du système d'antennes distribué de convertir le premier signal modulé à la première fréquence porteuse en premier signal modulé dans un premier segment spectral. Le signal de référence est reçu à une fréquence hors bande par rapport au canal de commande. L'invention concerne également d'autres modes de réalisation.
