Abstract

L'invention concerne un procédé d'envoi d'informations comprenant les étapes consistant à : déterminer une première ressource de domaine temporel occupée par un premier canal de commande de liaison montante dans une sous-trame de liaison montante, la première ressource de domaine temporel étant utilisée pour prendre en charge des premières informations de commande; déterminer une seconde ressource de domaine temporel occupée par un canal de service de liaison montante dans la sous-trame de liaison montante, la seconde ressource de domaine temporel comprenant la première ressource de domaine temporel, et la longueur de la première ressource de domaine temporel étant inférieure à la longueur de la seconde ressource de domaine temporel; déterminer le premier canal de commande de liaison montante ou le canal de service de liaison montante en tant que canal cible en fonction de la position de la première ressource de domaine temporel dans la sous-trame de liaison montante; et envoyer les premières informations de commande sur le canal cible. Au moyen des modes de réalisation de la présente invention, selon la position d'un canal sur lequel se produit un conflit dans une sous-trame de liaison montante, un canal cible destiné à envoyer des informations de commande de courant peut être déterminé, résolvant ainsi le problème selon lequel un conflit de ressources se produit pendant le processus de transmission de signal.
