Abstract

Sont présentés des systèmes et des procédés pour un nœud de réseau commandé par un équipement utilisateur (UE). Un nœud de réseau qui prend en charge un transfert contrôlable de signaux sans fil peut recevoir des premières informations de commande en provenance d'un dispositif de communication sans fil. Le nœud de réseau peut déterminer un comportement de transfert du nœud de réseau d'après les premières informations de commande.
