Abstract

La présente invention concerne un procédé et un dispositif de planification de liaison montante. Le procédé de planification de liaison montante selon la présente invention consiste à : déterminer des ressources de canal physique de liaison montante réservées respectivement à trois équipements d'utilisateur (UE) dans une période actuelle de réglage de ressources, les trois UE comprenant un premier UE comportant un retard de traitement de quatre sTTI, un deuxième UE comportant un retard de traitement de six sTTI et un troisième UE comportant un retard de traitement de huit sTTI ; obtenir la quantité de données mises en mémoire tampon d'un UE à planifier, ledit UE étant le premier UE, le deuxième UE ou le troisième UE ; et attribuer audit UE des ressources de canal physique de liaison montante à partir des ressources de canal physique de liaison montante réservées, selon la quantité de données mises en mémoire tampon. La présente invention permet d'améliorer l'utilisation des ressources de canal physique de liaison montante et d'assurer la QoS de l'UE.
