Abstract

L'invention concerne un procédé de transmission d'informations de commande en liaison montante, un équipement d'utilisateur, et un dispositif côté réseau. Le procédé de transmission d'informations de commande en liaison montante de la présente invention consiste à : déterminer un canal de code de destination parmi une pluralité de canaux de code prédéfinis ; et envoyer des informations en liaison montante à un dispositif côté réseau via le canal de code de destination, les informations en liaison montante comprenant des premières informations et des secondes informations, un bit d'informations transmis via le canal de code de destination transportant les premières informations et un code de découpage en canaux du canal de code de destination transportant les secondes données. Les modes de réalisation de la présente invention améliorent le débit en liaison montante d'un UE.
