Abstract

Des valeurs de seuil sont fournies pour gérer un débit HSUPA (High Speed Uplink Packet Access). Les valeurs de seuil sont déterminées à partir de critères particuliers. Après avoir reçu une commande d'augmenter une puissance de transmission, un UE ignore la commande quand le niveau de puissance minimum désigné d'un réseau dépasse la valeur de seuil.
