Abstract

Un sistema de comunicación por radio que tiene un canal (122) de comunicación entre una estación (100) primaria y una estación (110) secundaria, en el que la estación primaria comprende medios para emplear uno de una pluralidad de esquemas de transmisión para las transmisiones a la estación secundaria y en el que la estación secundaria comprende medios para determinar un parámetro (112) de calidad en relación con un canal (122) de comunicación de enlace descendente y medios que responden al parámetro de calidad determinado para enviar un informe de medición que indica una potencia de transmisión recomendada usando una tabla de informes de medición correspondiente a un esquema de transmisión a la estación primaria que es el esquema de transmisión más robusto de la pluralidad de esquemas de transmisión, en el que la estación primaria comprende medios (102) para determinar, a partir del informe de medición, unas potencias de transmisión respectivas para una pluralidad de esquemas de transmisión en función de una pluralidad de desplazamientos de potencia entre los esquemas de transmisión.
