Abstract

Divers aspects de la présente divulgation concernent un UE, une station de base et des procédés pour éviter une collision d'ID temporaires d'AS pour des dispositifs AIoT. Selon un aspect, un UE reçoit, en provenance d'une station de base, une gamme d'ID temporaires d'AS associées à l'UE. L'UE sélectionne une ID temporaire d'AS pour un dispositif AIoT dans la gamme d'ID temporaires d'AS. Ensuite, l'UE transmet l'ID temporaire d'AS sélectionnée au dispositif AIoT. L'ID temporaire d'AS indique que la transmission de données ou l'attribution de ressources radio est ciblée vers le dispositif AIoT.
