Abstract

Se describe un metodo y un aparato novedosos y mejorados para realizar el control de potencia de enlace directo de bucle cerrado utilizando una senal de enlace directo seleccionada, dedicada y controlada segun la potencia. Se estima una "Proporcion de Errores en Bitios de Senal Seleccionados" (SSBER) en donde cada "bitio" de la senal seleccionada consta de varios chips de senal seleccionados, distribuidos sobre una trama. Ademas, el metodo estima la variacion normalizada de la energia de senal (o C/I) para cada paquete. El numero promedio de indicadores en sincronia tambien se utiliza para determinar el punto de referencia para control de potencia.
