Abstract

Teniendo en cuenta el consumo de energía y el PH de un aparato de estación móvil en un enlace ascendente, mientras que la calidad de la comunicación se mantiene, la eficacia del consumo de energía se mejora. Se proporcionan una sección de recepción de PUSCH 14 para recibir una señal de PUSCH (Canal Compartido de Enlace Ascendente Físico) del aparato de estación móvil; una sección de detección de PH 15 para detectar el PH (Margen de maniobra de Energía) de la señal de PUSCH recibida; una sección de determinación de número de antena de transmisión 16 para determinar, desde el PH detectado, el número de antenas de transmisión que el aparato de estación móvil usa; una sección de generación de DCI 10 para generar DCI (Información de Control de Enlace Descendente) basada en información de asignación de frecuencia del aparato de estación móvil en el enlace ascendente; y una sección de transmisión de PDCCH 11 para convertir el DCI generado y la información de número de antena de transmisión determinado en una señal de PDCCH (Canal de Control de Enlace Descendente Físico) para transmitir la señal de PDCCH al aparato de estación móvil.
