Abstract

Selon l'invention, une configuration est reçue indiquant qu'un UE doit fonctionner dans un mode à latence réduite. L'UE détermine des informations de commande de liaison montante à signaler en utilisant un canal de commande de liaison montante physique courte. L'UE détermine une ressource de canal de commande de liaison montante physique courte pour transmettre les informations de commande de liaison montante. La ressource de canal de commande de liaison montante physique courte déterminée est une ressource de canal de commande de liaison montante physique à mode de latence réduite. La ressource de canal de commande de liaison montante physique courte comprend une première et une deuxième instance de séquence DMRS de liaison montante de longueur 12 LTE Rel-8 transmise dans un ou plusieurs symboles DFT-S-OFDM sur un premier bloc de ressource physique, suivis par une troisième et une quatrième instance de la séquence DMRS de liaison montante de longueur 12 LTE Rel-8 transmise dans un ou plusieurs symboles DFT-S-OFDM sur un deuxième bloc de ressources physiques. L'UE transmet les informations de commande de liaison montante sur la ressource de canal de commande de liaison montante physique à mode de latence réduite déterminé.
