Abstract

La présente invention concerne un procédé et un appareil de commande de puissance et un dispositif. Le procédé comprend : la détermination d'informations de période indiquant qu'une intensité de signal reçu d'un dispositif de terminal est supérieure ou égale à une première valeur de seuil ; selon les informations de période, le fait de déterminer qu'une intensité de signal reçu du dispositif de terminal sur au moins un symbole dans le prochain créneau temporel est supérieure ou égale à la première valeur de seuil ; et le réglage de la puissance reçue du dispositif de terminal selon l'intensité de signal reçu maximale du dispositif de terminal dans le créneau temporel actuel et selon la première valeur de seuil. La précision de la commande de puissance est améliorée.
