Abstract

La présente invention concerne un procédé de commande d'une transmission en liaison montante et un appareil associé. Selon un premier mode de réalisation de l'invention, le procédé permettant à un point de transmission de commander la transmission en liaison montante dans un réseau de communication mobile comprend les étapes consistant : à générer des premières informations de configuration destinées à indiquer un saut de fréquence à appliquer à la transmission en liaison montante d'un terminal ; et à transmettre, au terminal, un premier signal comprenant les premières informations de configuration, un point de réception, différent du point de transmission, recevant un second signal auquel les premières informations de configuration sont appliquées à partir du terminal.
