Abstract

Des modes de réalisation de la présente invention concernent un procédé de configuration et un dispositif de communication. Le dispositif de communication sert de premier dispositif de communication et comprend : une unité d'envoi, pour envoyer des premières informations d'instruction à un second dispositif de communication, les premières informations d'instruction envoyées par l'unité d'envoi étant utilisées pour ordonner l'utilisation d'une première configuration de communication, et la première configuration est une configuration réalisée pour la première fois ou une configuration réalisée après la reconfiguration entre le premier dispositif de communication et le second dispositif de communication ; et une unité de traitement, pour communiquer avec le second dispositif de communication en fonction des premières informations d'instruction envoyées par l'unité d'envoi. De cette manière, le premier dispositif de communication et le second dispositif de communication utilisent de manière synchrone la première configuration pour une communication déclenchée par les premières informations d'instruction.
