Abstract

Varias modalidades de la presente invención proporcionan un método para la operación de HARQ optimizada. El método comprende transmitir una transmisión de datos de enlace ascendente en el recurso de enlace ascendente compartido a un nodo de red y recibir un mensaje de retroalimentación desde el nodo de red, en donde el mensaje de retroalimentación comprende una indicación de retroalimentación que indica un estado de recepción de la transmisión de datos de enlace ascendente desde el dispositivo terminal. De acuerdo con las modalidades de la presente invención, la retroalimentación de HARQ explícita se puede proporcionar para la transmisión de datos de enlace ascendente en una red de comunicación inalámbrica tal como una red NR.
