Abstract

Dans un équipement utilisateur (420), procédé et agencement (800) permettant de communiquer des informations sur l'état d'un canal (CSI), et procédé et agencement (1000) dans une station de base (410) pour l'obtention d'informations sur l'état d'un canal (CSI). L'équipement utilisateur (420) est connecté à la station de base (410) au sein d'un réseau de communication cellulaire (400). Après réception (702) d'une autorisation dans une sous-trame n devant être utilisée pour la communication des informations sur l'état d'un canal (CSI) et transmise par la station de base, l'équipement utilisateur détermine (703) le type de sous-trame d'une sous-trame n+p. Ensuite, l'équipement utilisateur communique (704) à la station de base les informations sur l'état d'un canal (CSI) qui reflètent les conditions du canal dans le type de sous-trame d'une sous-trame n+p, p étant une valeur variable.
