Abstract
Las modalidades incluyen métodos para la transmisión de enlace descendente (DL) por un nodo de red en una red de retroceso de acceso integrado (IAB). Dichos métodos incluyen recibir, desde un nodo ascendente en la red, primera información de desplazamiento de sincronización relacionada con las comunicaciones entre el nodo de red y el nodo ascendente. Dichos métodos incluyen transmitir una señal o canal de DL, a uno o más nodos descendentes, con base en una sincronización de transmisión de DL para el nodo de red. La sincronización de transmisión de DL se determina a partir de la sincronización de recepción de DL del nodo de red de señales o canales transmitidos por el nodo ascendente y una segunda función de la primera información de desplazamiento de sincronización, que se determina con base en una primera función de la primera información de desplazamiento de sincronización (cuando la primera función es mayor que un umbral) o en un desplazamiento de sincronización alternativo (cuando la primera función no es mayor que el umbral). Las modalidades también incluyen nodos de red configurados para llevar a cabo tales métodos.
