Abstract

La présente invention concerne un procédé et un dispositif destinés à des stations de base et des unités d'abonnés, permettant un transfert cohérent d'un lien inverse AMCR à structure de canaux orthogonale. Des unités d'abonnés émettent un signal à codage orthogonal destiné aux stations de base, par un lien inverse. Une station de base donnée réalise la commande temporelle du décalage temporel du signal de lien inverse. En se basant sur au moins un critère, un dispositif d'alignement détermine si la station de base donnée doit transférer le commande temporelle à une autre station de base, et il en résulte un processus de transfert cohérent. En réponse à une commande ou à un message de transfert cohérent de l'unité d'abonné, de la station de base donnée à une autre station de base, l'unité d'abonné réalise un réglage temporel grossier sur le signal codé. L'unité d'abonné peut réaliser des réglages temporels précis en se basant sur des informations de rétroaction issues de la station de base responsable de la commande temporelle. De multiples stations de base peuvent fournir à l'unité d'abonné des informations de rétroaction de commande de puissance.
