Abstract

La présente invention porte sur un système de duplexage par répartition temporelle (TDD), et sur une structure de trame dynamique et un procédé de configuration qui sont basés sur le système TDD. Une sous-trame est sélectionnée dans une trame radio à titre de sous-trame dynamique, et la sous-trame dynamique peut avoir divers états, les états comprenant : un état de sous-trame de liaison montante, un état de sous-trame de liaison descendante et un état de sous-trame vide. Dans le système TDD, au niveau de la frontière entre des zones adjacentes ayant des configurations liaison montante/liaison descendante (UL/DL) différentes ou lorsque la configuration UL/DL est changée au niveau d'une sous-zone dans une zone ayant une certaine configuration UL/DL, le chevauchement entre la sous-trame de liaison montante et la sous-trame de liaison descendante au niveau des cellules adjacentes ayant des configurations UL/DL différentes peut être évité par ajustement de l'état de sous-trame dynamique, ce qui permet d'éliminer le brouillage entre la sous-trame de liaison montante et la sous-trame de liaison descendante; et lorsque le style de service d'une certain cellule change, elle peut disposer d'une certaine souplesse pour basculer vers d'autres configurations UL/DL.
