Abstract

Les modes de réalisation de la présente invention concernent un procédé de communication, un dispositif terminal et un dispositif de réseau. Au cours dudit procédé, un dispositif terminal reçoit une signalisation de commande de liaison descendante envoyée par un dispositif de réseau. La signalisation de commande de liaison descendante contient un premier domaine d'informations et un second domaine d'informations. Lorsque la valeur du premier domaine d'informations est une première valeur numérique, le second domaine d'informations est utilisé pour indiquer un premier paramètre. Le premier paramètre sert à transmettre des premières informations de rétroaction sur une unité de temps correspondant à la première valeur numérique. Lorsque la valeur du premier domaine d'informations est une seconde valeur numérique, le second domaine d'informations est utilisé pour indiquer un second paramètre différent du premier. Le procédé de communication, le dispositif terminal et le dispositif de réseau d'après les modes de réalisation de la présente invention peuvent accroître la flexibilité d'une signalisation de commande de liaison descendante.
