Abstract

Des modes de réalisation de la présente divulgation divulguent un procédé et un appareil d'attribution de ressources de domaine temporel, un dispositif et un support d'enregistrement, qui peuvent être appliqués à un système de communication. Lorsqu'il est exécuté par un dispositif de réseau, le procédé consiste à : acquérir une première table d'attribution de ressources de domaine temporel par défaut définie pour un dispositif terminal de premier type; et envoyer un canal de données de liaison descendante au dispositif terminal de premier type sur la base de la première table d'attribution de ressources de domaine temporel par défaut, la première table d'attribution de ressources de domaine temporel par défaut étant utilisée pour attribuer une ressource de domaine temporel au canal de données de liaison descendante associé au dispositif terminal de premier type, la première table d'attribution de ressources de domaine temporel par défaut et une seconde table d'attribution de ressources de domaine temporel par défaut étant différentes, et la seconde table d'attribution de ressources de domaine temporel par défaut étant utilisée pour attribuer une ressource de domaine temporel à un canal de données de liaison descendante associé à un dispositif terminal de second type. Au moyen de la mise en œuvre du procédé de la présente divulgation, un effet d'attribution de ressources de domaine temporel peut être efficacement amélioré sur la base d'une première table d'attribution de ressources de domaine temporel par défaut, ce qui permet d'améliorer efficacement la capacité de couverture d'un canal de données de liaison descendante.
