Abstract

Les modes de réalisation de la présente invention concernent un procédé, un dispositif et un système d'émission de signal, destinés à accélérer l'émission de signaux de liaison montante d'un appareil terminal à un appareil de réseau. Le procédé comporte les étapes suivantes: un appareil terminal détermine une première puissance d'émission d'un premier signal de liaison montante à envoyer à un premier appareil de réseau au cours de premières unités temporelles, et l'appareil terminal détermine une deuxième puissance d'émission d'un second signal de liaison montante à envoyer à un second appareil de réseau au cours de secondes unités temporelles, les premières unités temporelles et les secondes unités temporelles comprenant une partie de temps de chevauchement; et si la somme de la première puissance d'émission et de la deuxième puissance d'émission est supérieure à une puissance maximale d'émission de l'appareil terminal, l'appareil terminal détermine des niveaux de priorité du premier signal de liaison montante et du second signal de liaison montante selon le nombre de répétitions du premier signal de liaison montante et le nombre de répétitions du second signal de liaison montante, et réduit une puissance d'émission d'un signal de liaison montante doté d'un bas niveau de priorité, priorisant et garantissant ainsi une puissance d'émission d'un signal de liaison montante doté d'un haut niveau de priorité.
