Abstract

Selon cette invention, les effets du brouillage de la liaison descendante à la liaison montante sont atténués dans les systèmes TDD par adaptation de la temporisation des informations de commande de liaison montante et de la retransmission HARQ UL. Dans certains modes de réalisation, les informations de commande de liaison montante peuvent être déplacées jusqu'à des secteurs de trame qui subissent un brouillage de liaison descendante plus faible provenant d'autres cellules. Dans certains modes de réalisation, la temporisation HARQ UL est modifiée de sorte que les transmissions et retransmissions UL aient des profils de brouillage similaires. Selon des modes de réalisation, la HARQ UL non synchronisée peut servir à ordonnancer les retransmissions dans des secteurs de trame UL avec des profils de brouillage similaires à la transmission d'origine (par exemple un brouillage UL-UL, un brouillage DL-UL, etc.). Dans d'autres modes de réalisation, la temporisation HARQ UL synchrone modifiée adapte la retransmission afin qu'elle ait lieu sur des secteurs de trame UL ayant des profils de brouillage similaires à la transmission, sur la base de la configuration UL-DL TDD de la cellule de desserte et/ou des cellules provoquant le brouillage.
