Abstract

L'invention concerne un procédé de transmission d'un canal de commande partagé à liaison descendante comprenant un signal de commande nécessaire pour restaurer un signal de données de transmission dans un système de communication mobile qui transmet un signal de données à l'aide de multiples anntennes. On détermine si le signal de données de transmission est codé avec deux ou plusieurs autres mots de codage avant d'être transmis. Un premier index d'éléments d'un sous-livre de codes configuré seulement avec un précodage spécifique à un mot de codage dans un livre de codes de précodage ou un second index d'éléments d'un sous-livre de codage configuré seulement avec un précodage spécifique à plus de deux mots de codage est sélectionné en fonction du résultat déterminé. Un canal de commande est généré grâce à l'index d'éléments sélectionné dans les informations de précodage. Le canal de commande généré est mappé par rapport à un bloc de ressources particulier et le canal de commande mappé est transmis à un appareil de réception particulier.
