Abstract

L'invention concerne un procédé et un appareil d'attribution d'une ressource de canal de commande de liaison montante physique, et un système de communication. Le procédé comprend les étapes suivantes : un équipement utilisateur détermine une ressource d'un canal de commande de liaison montante physique conformément au numéro de série d'un élément de canal de commande du canal de commande de liaison descendante physique, et/ou au nombre d'éléments de canal de commande entre un premier intervalle temporel de transmission correspondant au canal de commande de liaison descendante physique et un second intervalle temporel de transmission correspondant au canal de commande de liaison montante physique. Ainsi, le problème de collision entre des ressources PUCCH peut être efficacement réduit ou empêché.
