Abstract

L'invention concerne un procédé et un appareil de configuration de séquence temporelle de sous-trame, un dispositif côté réseau et un dispositif côté terminal, qui peuvent garantir l'utilisation normale de la transmission de données entre le dispositif côté réseau et le dispositif côté terminal lorsqu'une bande de fréquence d'une norme de duplexage par répartition dans le temps (TDD) est comprise dans la colocalisation de bande de fréquence. Le procédé comprend les étapes suivantes : dans une ou plusieurs plages de fréquences de liaison montante et une ou plusieurs plages de fréquences de liaison descendante de bandes de fréquence de travail prises en charge par un dispositif côté réseau, déterminer une plage de fréquences de liaison montante et une plage de fréquences de liaison descendante qui sont appariées, de façon à obtenir des bandes de fréquences appariées ; configurer une séquence temporelle de sous-trames de liaison montante et de liaison descendante d'une porteuse sur les bandes de fréquence appariées, de façon à obtenir des informations de configuration de la séquence temporelle de sous-trames de liaison montante et de liaison descendante ; et diffuser les informations de configuration de la séquence temporelle de sous-trame de liaison montante et de liaison descendante à un dispositif côté terminal.
