Abstract

La présente invention concerne un procédé et un dispositif de transmission d'informations, ainsi qu'un terminal. Le procédé consiste : à déterminer qu'il existe une période de chevauchement entre un temps convenu de transmission d'informations de commande de liaison montante (UCI) correspondant à un premier intervalle de temps de transmission et un temps convenu de transmission d'un canal correspondant à un second intervalle de temps de transmission, le premier intervalle de temps de transmission étant plus court que le second intervalle de temps de transmission ; à envoyer un signal cible pendant la période de chevauchement.
