Abstract

Se proporciona un aparato (10) y metodo (100) para el control de la potencia de rango dinamico de una senal de comunicacion (85) de enlace descendente inalambrica, tales ajustes de la calidad de la senal objetivo se mantienen temporalmente (102) cuando es aparente que los comando del control de la potencia de transmision no produciran la respuesta deseada en la estacion transmisora. Las comparaciones de la senales recibidas medidas con los umbrales se llevan a cabo (111, 113, 117, 120) para determinar si la estacion transmisora ha alcanzado ya sea la potencia de transmision maxima o minima, en cuyo caso el ajuste de la calidad de la senal objetivo se controla en consecuencia (112, 114). Cuando se detecta (118, 121) la potencia de transmision normal, los ajustes de la calidad de la senal objetivo se autorizan para reiniciar de acuerdo a lo usual.
