Abstract

L'invention concerne un procédé et un appareil de transmission d'informations de liaison montante, ledit procédé comprenant les étapes suivantes : un dispositif terminal détermine un premier canal et un second canal, la priorité du premier canal étant supérieure à la priorité du second canal, les ressources de domaine temporel du premier canal chevauchant les premières ressources de domaine temporel dans le premier canal du second canal, le premier canal étant utilisé pour transporter des premières informations de liaison montante, les premières informations de liaison montante étant des informations de rétroaction correspondant à des premières données de liaison descendante, et le second canal étant utilisé pour transporter des secondes informations de liaison montante ; d'après les informations de rétroaction correspondant aux premières données de liaison descendante, le dispositif terminal envoie des premières informations de liaison montante sur le premier canal ou envoie des secondes informations de liaison montante sur le second canal. La présente solution technique est utilisée pour résoudre le problème d'un dispositif terminal transmettant des informations de liaison montante lorsque le dispositif terminal doit renvoyer des informations de rétroaction des données de planification semi-persistantes et doit envoyer d'autres informations de liaison montante sur les mêmes ressources de domaine temporel.
