Abstract

Se describe un dispositivo de estación móvil que incluye: una unidad de estimación de calidad de canal que calcula la calidad de canal de un enlace de enlace descendente de acuerdo con una señal de referencia de una estación de base y que da salida al resultado de la estimación como la información de estimación de canal; una unidad de determinación de confirmación de la transmisión que establece si la recepción del canal de datos de enlace descendente de la estación de base es con buenos resultados y da salida al resultado de la determinación como la información de confirmación de transmisión; y una unidad de prioridad de información de confirmación de entrega que decide el regreso de la información de confirmación de entrega con una prioridad más alta cuando la información de estimación de canal y la información de confirmación de entrega vayan a ser regresadas, de manera simultánea, a la estación de base.
