Abstract

La présente invention concerne un procédé de transmission d'informations, un dispositif terminal, et une station de base. Le procédé de transmission d'informations comprend les étapes suivantes : un dispositif terminal reçoit des informations de commande de liaison descendante de groupe en provenance d'une station de base ; et le dispositif terminal exécute une opération correspondant aux informations de commande de liaison descendante de groupe lorsqu'il est déterminé qu'un identifiant temporaire de réseau radio (RNTI) de groupe du groupe où le dispositif terminal se trouve est identique à un identifiant temporaire de réseau radio (RNTI) de groupe porté dans les informations de commande de liaison descendante de groupe, le RNTI de groupe du groupe dans lequel se trouve le dispositif terminal étant attribué par la station de base sur la base du type du dispositif terminal. L'invention concerne également un dispositif terminal et une station de base. Au moyen du procédé de transmission d'informations fourni dans les modes de réalisation de la présente invention, un dispositif terminal peut utiliser un RNTI de groupe pour recevoir des informations de commande de liaison descendante de groupe envoyées par une station de base à chaque dispositif terminal dans le groupe où se trouve le dispositif terminal, c'est-à-dire que la station de base envoie un élément d'informations de commande de liaison descendante à chaque dispositif terminal dans le même groupe, de telle sorte que le nombre de messages est réduit, ce qui améliore l'efficacité d'un réseau.
