Abstract

Dans ses modes de réalisation, la présente invention se rapporte à un procédé de transmission de signaux, à un équipement d'utilisateur (UE) et à un dispositif sur le côté réseau. Le procédé selon l'invention comprend l'étape suivante : dans le cas où un UE transmet une pluralité de types de signaux sur la liaison montante à un dispositif sur le côté réseau au moyen de deux avances temporelles, ou plus, l'UE envoie des informations en superposition, d'au moins deux types de signaux sur la liaison montante parmi la pluralité de types de signaux sur la liaison montante, au dispositif sur le côté réseau. Selon les modes de réalisation de la présente invention, l'UE peut transmettre des informations en superposition, d'une pluralité de types de signaux sur la liaison montante, au dispositif sur le côté réseau. De cette manière, le dispositif sur le côté réseau peut savoir si la pluralité de types de signaux sur la liaison montante se superposent, ou non. Le dispositif sur le côté réseau peut alors exécuter le traitement correspondant, résolvant ainsi le problème lié au fait que le rapport de la puissance de crête à la puissance moyenne des signaux sur la liaison montante est élevé.
