Abstract

Un método de control de potencia en una disposición de comunicaciones de radio y un nodo de control de red de radio. Se controlan las potencias de transmisión de enlace descendente de las estaciones de base comprendidas en una comunicación de transferencia en diversidad con una estación móvil para minimizar el ''deslizamiento'' de potencia de la estación de base. Se determina un nivel de volumen de referencia de enlace descendente basado en los niveles de potencia de transmisión corriente de las estaciones de base en diversidad. Se determina una o más desviaciones para una o más de las estaciones de base basadas en las mediciones de calidad de senal hechas por la estación móvil. El nivel del volumen de referencia y la desviación (es) de potencia se utilizan para regular un ajuste a los niveles de potencia de transmisión de las estaciones de base de transferencia en diversidad. Se transmite el volumen de referencia general en una frecuencia primera relativamente alta a las estaciones de base de transferencia en diversidad mediante el empotrado en un marco de datos del usuario. De esa manera, se mantiene la carga del proceso de senal en un mínimo a pesar de la frecuencia superior de transmisión. Las desviaciones de potencia individual se envían a las estaciones de base individuales asociadas en un canal de senalización de control identificando una estación de base en una segunda frecuencia inferior a la de la primera frecuencia. La senalización de canal de control permite las desviaciones de potencia de estación individual, pero la frecuencia inferior en la cual se transmiten las desviaciones reduce la carga de senalización asociada.
