Title (EN) SYSTEMS AND METHODS FOR FORWARDING A MULTI-USER RF SIGNAL
(FR) SYSTÈMES ET PROCÉDÉS DE TRANSMISSION D'UN SIGNAL RF MULTI-UTILISATEURS
Abstract:
(EN) A dynamic frequency translating repeater operating in a mobile communications system is operable to receive a multi-user signal and perform time-varying and user- specific frequency shifting in the repeater signal. The dynamic frequency translating repeater may further perform user subcarrier specific dynamic frequency translation. Different mobile stations may be allocated different frequency shift amounts based on the interference environments, resource allocations, and scheduling constraints particular to each mobile station.
(FR) Un répéteur à transposition de fréquence dynamique fonctionnant dans un système de communications mobiles sert à recevoir un signal multi-utilisateurs et à réaliser dans le signal de répéteur un déplacement de fréquence qui varie avec le temps et qui est spécifique à un utilisateur. Ce répéteur à transposition de fréquence dynamique peut réaliser en outre une transposition de fréquence dynamique spécifique à la sous-porteuse d'un utilisateur. Différentes stations mobiles peuvent se voir affecter différentes quantités de déplacement de fréquence en fonction des environnements comportant des brouillages, des affectations de ressources et des contraintes de planification propres à chaque station mobile.
