Abstract

Se describen sistemas y métodos para la señalización eficiente de acuse de recibo de solicitud de repetición automática híbrida (HARQ-ACK) para una transmisión de datos de enlace ascendente. En algunas modalidades, un método de señalización de retroalimentación de HARQ-ACK para una transmisión de datos de enlace ascendente enviada de un dispositivo inalámbrico a un nodo de red de radio comprende obtener retroalimentación de HARQ-ACK para la transmisión de datos de enlace ascendente, codificar la retroalimentación de HARQ-ACK obtenida hacia una combinación de bits no usados de un campo en un canal de control de enlace descendente, y transmitir el canal de control de enlace descendente al dispositivo inalámbrico. Las modalidades de la presente invención permiten el ahorro de energía del dispositivo inalámbrico usando retroalimentación de HARQ-ACK positivo sin aumentar la sobrecarga de señalización de control de enlace descendente estático y sin reducir la cobertura para información de control de enlace descendente.
