Abstract

Un procédé et un appareil de commande de puissance rayonnée isotrope efficace, et un support d'enregistrement sont divulgués. Le procédé comprend les étapes suivantes : une station de base envoie une demande de mesure à un équipement utilisateur ; la station de base reçoit respectivement un identifiant de faisceau, une valeur de niveau de faisceau et des informations de position, qui correspondent à l'équipement utilisateur et qui sont envoyés par l'équipement utilisateur, et détermine un angle d'inclinaison vers le bas de la station de base en fonction d'informations de position de la station de base, et de l'ID de faisceau, de la valeur de niveau de faisceau et des informations de position correspondant à l'équipement utilisateur ; la station de base détermine un ensemble de faisceaux d'air dans une plage prédéfinie ; et pour tout faisceau A dans l'ensemble de faisceaux d'air, si la puissance rayonnée isotrope efficace initiale du faisceau A est supérieure à un seuil prédéfini, la station de base règle la puissance rayonnée isotrope efficace initiale du faisceau A, de manière à obtenir une puissance de rayonnement isotrope efficace cible du faisceau A. Au moyen des moyens ci-dessus, le but du réglage adaptatif de la puissance rayonnée isotrope efficace (EIRP) d'un faisceau peut être obtenu.
