Abstract

Método para controlar la potencia de transmisión de estaciones base en un sistema de telecomunicaciones que comprende estaciones móviles y estaciones base, en el que una estación móvil recibe simultáneamente señales de información desde múltiples estaciones base, caracterizado porque la diferencia en la potencia utilizada o en la energía por bit utilizada entre cada una de dichas múltiples estaciones móviles que transmiten hacia dicha estación móvil se reduce: determinando, con vistas a la ejecución de un algoritmo de corrección de la potencia, comprendiendo los parámetros de corrección de la potencia por lo menos un intervalo de corrección de la potencia, unos límites de la magnitud de los pasos de corrección y un(os) nivel(es) de potencia objetivo o un(os) nivel(es) de energía objetivo para cada una de dichas múltiples estaciones base; y ejecutando dicho algoritmo de corrección de la potencia en cada una de dichas múltiples estaciones base.
