Abstract

La présente invention concerne un procédé, un procédé et un appareil de communication pour une utilisation dans le domaine des communications mobiles. Le procédé comprend les étapes suivantes : des DCI et des informations de configuration en provenance d'un dispositif de réseau sont reçues, et si une valeur obtenue d'un premier champ dans les DCI est identique à un indice d'une autorisation configurée de type 2, et une valeur d'un champ FDRA au sein des DCI satisfait des conditions préétablies, il est déterminé que les DCI n'ont pas besoin de libérer une autorisation configurée de type 2, les conditions prédéfinies comprenant : un type d'attribution de ressources de l'autorisation configurée de type 2 est de type 0 et tous les chiffres de la valeur du champ FDRA ne sont pas à zéro, ou le type d'attribution de ressources de l'autorisation configurée de type 2 est de type 1 et tous les chiffres de la valeur du champ FDRA ne sont pas à un. Dans un scénario de libération combiné, la présente solution peut garantir que lorsqu'une valeur d'un champ FDRA Indique qu'une DCI d'activation n'est pas en vigueur, il est indiqué qu'une DCI de libération est en vigueur, c'est-à-dire que des fonctions DCI peuvent être distinguées, ce qui améliore les performances des DCI de libération en validation.
