Abstract

L'invention concerne un contrôle de processus de requête de répétition automatique hybride (HARQ) et un procédé et un appareil d'étalonnage, et une station de base. Un état d'activation cible, envoyé par une station de base à un terminal, d'un processus HARQ cible est acquis, et un état d'activation réel actuel d'un processus HARQ cible sur un côté terminal est acquis ; l'état d'activation cible est comparé avec l'état d'activation réel, on détermine si l'état d'activation cible est cohérent avec l'état d'activation réel, et de cette manière, il est possible de savoir si le processus HARQ activé ou désactivé du terminal est cohérent avec un processus HARQ planifié par un Nœud B ; et en cas d'incohérence, une notification d'anomalie est générée, et l'état d'activation du processus HARQ sur le côté terminal est étalonné selon la notification d'anomalie.
