Abstract

La présente invention concerne un procédé et un dispositif de transmission d'informations de commande de liaison montante. Le procédé comprend les étapes suivantes : recevoir, par un terminal, des informations de commande communes de liaison descendante envoyées par un appareil de réseau, les informations de commande communes de liaison descendante étant utilisées pour indiquer une ressource de transmission utilisée par chaque terminal dans un groupe de terminaux pour transmettre des informations de commande de liaison montante, et le terminal est un terminal quelconque dans le groupe de terminaux ; et envoyer, par le terminal, sur la ressource de transmission, les informations de commande de liaison montante à l'appareil de réseau. Grâce à des informations de commande communes de liaison descendante indiquant simultanément à un groupe de terminaux une ressource de transmission pour transmettre des informations de commande de liaison montante, le problème dans l'état de la technique selon lequel un appareil de réseau doit envoyer respectivement, à chaque terminal, des informations d'indication pour indiquer une ressource de transmission pour que le terminal transmette des informations de commande de liaison montante est évité, ce qui réduit le temps système nécessaire pour envoyer de la signalisation lorsque l'appareil de réseau configure, pour le terminal, la ressource de transmission pour les informations de commande de liaison montante.
