Abstract

Técnicas para llevar a cabo el control de la potencia de multiples canales enviados mediante la utilizacion de multiples tecnologías de radio. La potencia de transmision de un canal de referencia, enviado mediante la utilizacion de una primera tecnología de radio (por ejemplo, el CDMA), se ajusta para lograr un nivel objeto de rendimiento (por ejemplo, una velocidad de borrado objeto) para e canal de referencia. La potencia de transmision de un canal de datos, enviado mediante la utilizacion de una segunda tecnología de radio, (por ejemplo, el OFDMA), se ajusta sobre la base de la potencia de transmision del canal de referencia. En un esquema para el control de la potencia, se determina un nivel de referencia para la densidad espectral de la potencia (PSD) sobre la base de la potencia de transmision del canal de referencia. Se ajusta un delta de PSD de transmision para el canal de datos sobre la base de estimaciones de la interferencia. Se determina un PSD de transmision del canal de datos sobre la base del nivel de referencia para la PSD y del delta de PSD de la transmision. A continuacion se configura la potencia de transmision del canal de datos para lograr el PSD de transmision para el canal de datos.
