Abstract

En un aspecto, uno o más nodos de red configurados controlan el uso de la duplicación de datos (DD) para un UE servido simultáneamente por dos o más unidades de transmisión distribuidas (DUs) que reciben información de retroalimentación de una o más de las DUs. El uno o más nodos de red determinan, en función de la información de retroalimentación, si activar DD para las transmisiones al UE.
