Abstract

La présente invention se rapporte au domaine technique des communications sans fil, et concerne en particulier un terminal, un dispositif de réseau et un procédé de transmission pour des informations de commande en liaison montante, qui sont utilisés pour résoudre le problème lié au fait que le déclenchement d'un mode de compte rendu d'informations de commande en liaison montante contrôlé par les bits occupe une importante surcharge de signalisation de commande d'un canal de commande en liaison descendante. Dans le terminal décrits dans les modes de réalisation de la présente invention, un module de traitement détermine la programmation d'un premier élément correspondant à des premières informations de programmation émises par un premier canal de données en liaison montante à partir d'un ensemble d'informations de programmation, différents éléments représentant différents fragments d'informations de programmation; d'après une corrélation entre un élément de l'ensemble d'informations de programmation et un élément d'un ensemble de modes d'émission d'informations de commande en liaison montante, un second élément, correspondant au premier élément, de l'ensemble de modes d'émission d'informations de commande en liaison montante est déterminé, et différents éléments représentent différents modes d'émission d'informations de commande en liaison montante; et un module d'émission émet des informations de commande en liaison montante selon un mode d'émission d'informations de commande en liaison montante représenté par le deuxième élément. Un mode d'émission d'informations de commande en liaison montante est déterminé implicitement au moyen d'informations de programmation, de façon à économiser des surcharges de signalisation de commande dans un canal de commande en liaison descendante.
