Abstract

La présente invention concerne un procédé de transmission de données, une station de base et un équipement utilisateur. Le procédé comprend les étapes suivantes : si une sous-trame de planification satisfaisant à une relation de cadencement de demande de répétition automatique hybride (HARQ, Hybrid Automatic Repeat Request) avec une première sous-trame est une sous-trame spéciale, déterminer alors qu'il est nécessaire d'envoyer des informations de commande de liaison descendante (DCI, Downlink Control Information) à l'équipement utilisateur (UE, User Equipment) dans une seconde sous-trame commune avant de planifier la sous-trame, les DCI étant utilisées pour planifier la transmission de données de liaison montante dans la première sous-trame commune ; envoyer les DCI à l'UE dans la seconde sous-trame commune ; et recevoir les données de liaison montante que l'UE envoie dans la première sous-trame commune sur la base des DCI. Conformément au procédé de transmission de données d'un mode de réalisation de la présente invention, la station de base effectue une planification de l'UE et un retour d'informations vers ce dernier dans la sous-trame commune dans le cas où la sous-trame spéciale existe, de manière à résoudre le problème d'impossibilité de l'exécution d'une transmission normale de données entre l'UE et la station de base du fait de l'existence de la sous-trame spéciale, cela améliorant les performances du système et l'expérience utilisateur.
