Abstract

La présente divulgation appartient au domaine technique des communications. Un procédé et un appareil de sélection de ressources à créneaux multiples consécutifs sont décrits, ainsi qu'un dispositif et un support de stockage. Le procédé comprend les étapes suivantes : un dispositif terminal détermine m blocs de transport (TB) qui atteignent une couche physique du dispositif terminal, m étant un entier positif supérieur à 1 ; et sélectionne, pour les m TB, des ressources qui sont consécutives dans le domaine temporel, et envoie respectivement les m TB sur les ressources sélectionnées qui sont consécutives dans le domaine temporel. Au moment de sélectionner des ressources pour n'importe quel TB parmi les m TB, un résultat de sélection de ressources d'un autre TB pour lequel une sélection de ressources a été exécutée avant le TB est pris en considération, le résultat de sélection de ressources étant une ressource qui a été sélectionnée et non utilisée pour une transmission réelle. Au moyen du procédé, des ressources qui sont consécutives dans le domaine temporel peuvent être déterminées pour M TB, ce qui permet de mettre en œuvre une sélection de ressources à créneaux multiples consécutifs, de réduire l'impact d'une défaillance LBT, et d'améliorer l'efficacité d'accès au canal.
