Abstract

La présente demande, qui relève du domaine technique des communications, concerne un procédé de traitement de transmission de liaison montante, et un terminal. Le procédé est appliqué à un terminal, et le terminal réalise les opérations suivantes dans le procédé : lorsqu'au moins deux canaux de transmission de liaison montante satisfont une condition de multiplexage dans le temps, un terminal transmet les deux canaux de transmission de liaison montante ou plus dans un mode de transmission par multiplexage ; lorsque les deux canaux de transmission de liaison montante ou plus satisfont une condition d'annulation dans le temps, le terminal transmet les deux canaux de transmission de liaison montante ou plus à l'aide d'un mode de transmission par annulation des transmissions de faible priorité. Le terminal prend en charge le mode de transmission par multiplexage et le mode de transmission par annulation des transmissions de faible priorité, et des ressources de domaine temporel des deux canaux de transmission de liaison montante ou plus se chevauchent.
