Abstract: La présente invention divulgue des procédés et des appareils permettant de réaliser une commutation de faisceau rapide dans un environnement de communication sans fil à haute fréquence. Des fréquences supérieures réduisent la longueur d'onde de transmission, ce qui permet un nombre accru d'antennes et un nombre accru de faisceaux. Par conséquent, les faisceaux deviennent plus étroits et sont plus sujets à des défaillances. L'UE doit être capable d'identifier rapidement la défaillance de faisceau et de basculer vers un nouveau faisceau. Par conséquent, l'UE est capable de recevoir de multiples faisceaux en provenance de la station de base et se configure à la fois pour les essais et pour l'utilisation immédiate. Dans certains cas, l'UE peut recevoir de multiples faisceaux pour les essais et choisit un faisceau par défaut tout en renvoyant à la station de base un faisceau préféré. Pour prendre en charge le plus grand nombre de faisceaux disponibles, le MAC-CE et les DCI sont modifiés pour identifier ce nombre accru d'états. Alternativement, deux MAC-CE contenant chacun un groupe différent d'états sont envoyés et les DCI identifient à la fois le groupe et l'état sélectionné.
