Abstract

La presente invención se refiere un dispositivo de terminal móvil (401), una estación base (400) y un método que hacen posible usar un formato de reporte de indicador de calidad de canal, CQl, para reporte de CQI desde el dispositivo de terminal móvil a la estación base, el cual formato de reporte de CQI depende de una donde dicha configuración de antena de transmisión seleccionada. El dispositivo de terminal móvil (400) está dispuesto para recibir una señal (404) desde un número de antenas de transmisión, la cual señal incluye un número de subportadoras (412), y para determinar el formato de reporte de CQl para una colección de las subportadoras con base en la donde dicha configuración de antena de transmisión seleccionada. El dispositivo de terminal móvil está dispuesto además para determinar un número de valores de CQI (409) con respecto a dichas subportadoras de conformidad con el formato de reporte de CQl y para transmitir los valores de CQI a la estación base en una señal de retroalimentación (408). El formato de reporte de CQV se adapta a la donde dicha configuración de antena de transmisión seleccionada de modo que la granularidad del reporte de CQI depende de la donde dicha configuración de antena de transmisión seleccionada.
