Abstract

L'invention concerne des techniques pour signaler les capacités d'une station mobile, qui font intervenir un index de capacités ainsi qu'un mécanisme de traitement de secours en cas de panne du système. L'index de capacités peut représenter de multiples capacités de la station mobile. Une station mobile peut signaler à la station de base les capacités de la station mobile au moyen de l'index de capacités. Une station de base peut interpréter l'index de capacités de la station mobile pour connaître ses capacités. La station de base peut signaler à la station mobile les capacités qu'elle prend en charge au moyen d'un index de capacités. Les capacités utilisées entre la station de base et la station mobile sont définies en fonction des capacités signalées par la station de base.
