Abstract
Des aspects de la présente invention peuvent comprendre, par exemple, la réception, par un élément de réseau d'un système d'antenne réparti, 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 des première données de communication fournies par une station de base et adressées à un dispositif de communication mobile. Les instructions dans le canal de commande amène l'élément de réseau du système d'antenne réparti à 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 intra-bande relativement au canal de commande. D'autres modes de réalisation sont divulgués.
