Abstract

La présente demande se rapporte au domaine technique des communications. L'invention concerne un procédé et un appareil de mise à jour d'état de tableau de score, et un dispositif et un support de stockage. Le procédé est exécuté par un dispositif multiliaison de station, dans lequel le dispositif multiliaison de station correspond à une première liaison à une nième liaison, n étant un nombre entier positif supérieur à 1. Le procédé comprend : en réponse à un premier tableau de scores MAC de couche basse sur une première liaison ayant reçu une trame de données, la détermination d'une manière de mise à jour d'état pour le premier tableau de scores MAC de couche basse sur la base des états d'un deuxième tableau de scores MAC de couche basse à un nième tableau de scores MAC de couche basse sur les n-1 autres liaisons, dans lequel le premier tableau de scores MAC de couche basse au nième tableau de scores MAC de couche basse correspond au même accord d'accusé de réception de bloc. Au moyen de la solution technique fournie dans les modes de réalisation de la présente invention, une manière de mise à jour d'état pour un tableau de scores MAC de couche basse qui a reçu une trame de données peut être déterminée rationnellement, améliorant ainsi le taux d'utilisation des ressources d'interface aérienne.
