Abstract
Una estación de transmisión recibe un comando de potencia de transmisión y una senal de referencia. El comando de potencia de transmisión indica un aumento o una disminución en potencia de transmisión para la estación de transmisión. Se mide un nivel de potencia recibida de la al de referencia y se compara el nivel de potencia recibida de la senal de referencia medida con un nivel de potencia de transmisión de la senal de referencia para producir un estimado de pérdida de trayectoria de la senal de referencia. Una magnitud de un cambio en nivel de potencia de transmisión es determinada utilizando elestimado de pérdida de trayectoria. Se ajusta un nivel de potencia de transmisión de la estación de transmisión como respuesta al comando de potencia de transmisión en una cantidad del cambio determinado en magnitud. Se transmite una comunicación en el nivel de potencia de transmisión ajustada.
