Abstract

Las modalidades de este documento se refieren al desplazamiento de avance de sincronización para la conmutación de enlace ascendente/enlace descendente en Nueva Radio (NR). En una modalidad, propone un método en un dispositivo de comunicación inalámbrica, que comprende: determinar un desplazamiento de avance de sincronización (TA) para la conmutación de enlace ascendente/enlace descendente, en donde el desplazamiento de TA se basa al menos en el requisito de desplazamiento de tiempo para la conmutación de enlace ascendente/enlace descendente en diferentes escenarios usados en la comunicación entre el dispositivo de comunicación inalámbrica y un nodo de red; aplicar el desplazamiento de TA determinado en la comunicación de enlace ascendente del dispositivo de comunicación inalámbrica al nodo de red. Con modalidades en el presente documento, se define el tiempo de conmutación de enlace ascendente/enlace descendente para NR.
