Abstract

Les modes de réalisation de la présente invention concernent un procédé et un dispositif de communication pour un spectre de fréquence non autorisé, lesquels sont susceptibles de transmettre des informations de retour d'un canal de liaison descendante en cas d'une transmission de multiplexage des informations de retour. Le procédé comprend les étapes suivantes : la détermination par un équipement terminal, en fonction d'une première unité temporelle dans un premier ensemble d'unités temporelles et une deuxième unité temporelle dans le premier ensemble d'unités temporelles, une première position de bit des informations de retour correspondant à un premier canal de liaison descendante, dans une séquence d'informations de retour, le premier ensemble d'unités temporelles comprenant au moins une unité temporelle continue, la première unité temporelle est la dernière unité temporelle ou la dernière unité temporelle de liaison descendante du premier ensemble d'unités temporelles, ou la première unité temporelle est déterminée en fonction de la dernière unité temporelle ou de la dernière unité temporelle de liaison descendante du premier ensemble d'unités temporelles, et la deuxième unité temporelle étant une unité temporelle occupée par le premier canal de liaison descendante ; et la génération par l'équipement terminal, en fonction de la première position de bit, de la séquence d'informations de retour.
