Abstract

La présente invention concerne des procédés d'envoi et de réception de sous-trames, une station de base et un UE. Une sous-trame complète est formée par l'épissage d'une sous-trame incomplète, qui se situe entre un moment de départ après qu'une station de base a occupé une porteuse sans licence et une position de départ d'une sous-trame suivante, avec d'autres sous-trames, et des données efficaces peuvent être envoyées à l'aide de la sous-trame incomplète, et en conséquence l'efficacité d'utilisation de porteuses sans licence est améliorée ; lorsque des données sont envoyées à partir de n'importe quel symbole, la station de base a seulement besoin de pré-coder des données d'une sous-trame complète à l'avance, un prétraitement est effectué sans qu'il soit nécessaire de traverser toutes les sous-trames complètes, et en conséquence les ressources de traitement sont économisées. Le procédé d'envoi de sous-trames comprend : une station de base alloue une porteuse sans licence à un UE ; la station de base détermine une première sous-trame incomplète après que la porteuse sans licence a été occupée, et détermine une sous-trame épissée qui a été épissée avec la première sous-trame incomplète ; la station de base code des données dans un TTI ; et la station de base envoie les données codées à l'UE au moyen de la première sous-trame incomplète de la porteuse sans licence et de la sous-trame épissée de celle-ci.
