Abstract

L'invention concerne une technologie applicable à un appareil d'une station source configurée pour un espacement de sous-porteuse variable (SCS). La station source peut coder une demande de livraison, à une station de destination, d'une pluralité de valeurs de SCS prises en charge, la pluralité de valeurs de SCS prises en charge étant prise en charge par la station de destination. La station source peut décoder la pluralité de valeurs de SCS prises en charge, reçues de la station de destination. La station source peut initier une communication par ondes millimétriques (mmWave) avec la station de destination à l'aide d'une valeur de SCS sélectionnée sur la base de la pluralité de valeurs de SCS prises en charge de la station de destination et d'une pluralité de valeurs de SCS prises en charge de la station de source. Une interface mémoire peut être configurée pour envoyer à une mémoire la pluralité de valeurs de SCS prises en charge de la station de destination.
