Dans le procédé selon la présente invention, un dispositif de réseau : envoie une trame de diffusion contenant des premières informations de durée et des secondes informations de durée relatives à un A-BFT ; et reçoit une trame envoyée dans un intervalle de temps sélectionné aléatoirement par un premier équipement d'utilisateur dans une première plage de temps, et reçoit une trame envoyée dans un intervalle de temps sélectionné aléatoirement par un second équipement d'utilisateur dans une seconde plage de temps. Les modes de réalisation de la présente invention peuvent améliorer l'efficacité d'un apprentissage de formation de faisceau.
