Abstract

Se divulgan sistemas y métodos de señalización eficaz de reconocimiento de solicitud de repetición automática híbrida (HARQ-ACK, Hybrid Automatic Repeat Request Acknowledgement) para una transmisión de datos de enlace ascendente. En algunas formas de realización, un método para señalizar realimentación HARQ-ACK en una transmisión de datos de enlace ascendente de un dispositivo inalámbrico a un nodo de red radioeléctrico comprende obtener la realimentación HARQ-ACK para la transmisión de datos de enlace ascendente; codificar la realimentación HARQ-ACK obtenida en una combinación de bits no utilizada de un campo en un canal de control de enlace descendente; y transmitir el canal de control de enlace descendente al dispositivo inalámbrico. Las formas de realización de la presente divulgación posibilitan el ahorro de energía en el dispositivo inalámbrico usando realimentación HARQ-ACK positiva sin aumentar la tara de señalización de control de enlace descendente estática y sin reducir la cobertura de la información de control de enlace descendente.
