Abstract

Dispositivos y métodos que facilitan la programacion por intermedio de un algoritmo para el control de la potencia que de manera dinámica actualiza una mérita de programacion (por ejemplo, mediante el ajuste de la potencia de transmision para subportadores) sobre la base de una funcion de prediccion y/o modelo de interferencia de los requisitos de potencia previstos. En un aspecto, el componente para la prediccion de la potencia puede incluir dos componentes adicionales, a saber: el componente canal de datos y el componente canal de control, en el que se está transmitiendo una informacion de la relacion entre portador e interferencia (C/I, carrier/ interference) sobre dicho canal de control, y se ajusta la potencia para obtener los requisitos en cuanto a rendimiento. Por lo tanto, es posible proveer una programacion eficiente de los usuarios en un enlace inverso de manera ortogonal, a efectos de utilizar de manera optima los recursos del sistema, manteniendose simultáneamente una métrica predeterminada y/o arbitraria de equidad, manteniendose la calidad del servicio y maximizándose el caudal.
