Abstract

La présente invention concerne diverses solutions de commande de puissance en boucle fermée (CLPC) par rapport à un équipement d'utilisateur et à un nœud de réseau. Un appareil peut recevoir une première configuration d'un nœud de réseau. La première configuration indique un premier état de réglage de commande CLPC et un second état de réglage de commande CLPC pour un signal de référence de sondage (SRS). L'appareil peut recevoir une seconde configuration du nœud de réseau pour une transmission d'un signal SRS. L'appareil peut déterminer l'application du premier état de réglage de commande CLPC ou du second état de réglage de commande CLPC pour la transmission du signal SRS selon la seconde configuration.
