Abstract

Se provee un control de potencia eficiente y efectivo en un sistema de comunicaciones moviles que se adapta a las condiciones de transmision de radiorápidamente cambiantes en situaciones variables y a menudo impredecibles. El valor de un parámetrode senal detactado a partir de una senal recibida por untransceptor de radio se compara con un valor de parámetro de senal deseada, y se determina una diferencia. Un comando de control de potencia de transmision seenvía al transceptor de radio ypuede instruir por ejemplo, un aumento disminucion en el nivel de potencia transmitida de radio. Incluido con el comando decontrol de potencia transmitida está un indicador de control de potencia que indica si debe usarse un primer o segundo tipo deajuste de control de potenciapor parte del transceptor de radio que depende de la diferencia determinada. En una realizacion ejemplo, el indicador de potencia es un bit de marca unico. Unprimer valor indica que debe usarse el primer tipo de ajustede contr ol de potencia; el segundo valor indica que debe usarse el segundo tipo de ajuste decontrol de potencia. En cualquier caso, el indicador de control de potencia en sí mismo no incluye detalles específicos del primer o segundo tipo de ajustedecontrol de potencia. Debido a que solo se envía el indicador (y no los detalles), la sobrecarga de senalizacion y el consumo de ancho de banda relacionado conlos comandos de control de potencia enviados frecuentemente se mantienen al mínimo. Losdetalles esp ecíficos de los ajustes de control de potencia primero ysegundo se guardan inicialmente en el transceptor de radio. Dichos detalles se pueden actualizar cuando se desee, pero la frecuencia de dicha actualizacion esprobable que seainfrecuente. Altern ativamente, un indicador de control de potencia puede ser comunicado utilizando técnicas diferentes de la adicion de uno omás bits de marca a un mensaje de control de potencia transmitida rápida para efectuar un cambio en el tipode control de potenc ia en tanto y en cuanto lasobrecarga de senalizacion no esté significativamente aumentada.
