Abstract

Se proporcionan sistemas y métodos para la confirmación ACK/NACK de elemento de control (CE) de control de acceso a medio (MAC) confiable. En algunas modalidades, un método llevado a cabo por un dispositivo inalámbrico incluye: estar configurado con al menos un proceso de solicitud de repetición automática híbrida (HARQ) de retroalimentación habilitada mientras los procesos HARQ restantes del dispositivo inalámbrico tienen retroalimentación deshabilitada; recibir un comando de activación/desactivación que requiera retroalimentación, en donde la recepción usa al menos un proceso HARQ de retroalimentación habilitada; y/o transmitir retroalimentación con respecto al comando de activación/desactivac ión. De esta manera, el dispositivo inalámbrico está habilitado para enviar retroalimentación ACK/NACK de HARQ relacionada con comandos de CE de MAC de activación/desactivación críticos en una red no terrestre (NTN). Además, en presencia de un gran retraso unidireccional, esto asegura que no haya discrepancias entre la estación base y el dispositivo inalámbrico en cuanto a cuándo el dispositivo inalámbrico puede asumir que la información de activación/desactivación en el comando de CE de MAC puede tener efecto en el dispositivo inalámbrico.
