Abstract

L'invention concerne un procédé, un dispositif et un système de transmission d'informations de commande de liaison montante, ainsi qu'un support de stockage. Le procédé comprend les opérations suivantes : un terminal obtient un bloc de données envoyé par un premier dispositif côté réseau au moyen d'une première liaison, la première liaison comprenant une liaison reliant le terminal et le premier dispositif côté réseau ; le terminal envoie, selon le bloc de données et des informations configurées, des informations de commande de liaison montante (UCI) d'une couche physique au premier dispositif côté réseau au moyen d'un canal de commande de liaison montante physique (PUCCH) indiqué par les informations configurées. La situation dans laquelle des UCI ne peuvent pas être envoyées à un premier dispositif côté réseau normalement et à temps en raison du fait d'un accès multiple avec écoute de porteuse (LBT) est effectué sur une porteuse non autorisée, est évitée, de telle sorte que les UCI peuvent être envoyées au premier dispositif côté réseau correctement et à temps, permettant ainsi d'améliorer l'efficacité de transmission de données de liaison descendante d'un système.
