Abstract

L'invention concerne une couche d'adaptation de protocole définie dans une couche de commande d'accès au support d'un réseau de communication radio, et plus spécifiquement, sur une structure de supertrame et sur un procédé de synchronisation des périodes d'activation des différents dispositifs du réseau de communication radio. La supertrame transmise/reçue dans un réseau personnel comprend : une période de supertrame d'activation locale comprenant des informations relatives à la période d'une supertrame lorsqu'un dispositif est activé, et une zone de compte à rebours de la supertrame d'activation locale comprenant des informations concernant un nombre de supertrames restant à envoyer jusqu'à la transmission de la supertrame lorsque le dispositif est activé.
