Abstract

Se describen métodos para controlar los niveles de potencia de senales trasmitidas en sistemas de telecomunicaciones. Por ejemplo, una terminal remotamide la calidad de una senal recibida, ya sea determinando el índice de error de trama o el índice de errores de bitio e informa la medicion de su calidad auna red enviando un mensaje de calidad. La red hace que los transmisores de senal ajusten sus niveles de potencia de transmision adecuadamente. Los métodosde control de potencia más veloces pueden combinarse con métodos de control de potencia más lentos para las transmisiones downlink (red a terminal remota) endistintos escenarios de comunicacion, como por ejemplo transferencias suaves.
