Abstract

Un método llevado a cabo por un nodo de red que opera como una unidad distribuida (DU) incluye configurar una pluralidad de puntos de transmisión/recepción (TRPs) en un grupo de TRPs para transmitir una pluralidad de señales en una secuencia multiplexada a por lo menos un dispositivo inalámbrico. Cada TRP en el grupo de TRPs está asociado con una célula compartida. El nodo de red recibe, desde al menos un dispositivo inalámbrico, una señal de respuesta. Con base en la señal de respuesta, el nodo de red determina al menos un TRP del grupo de TRPs para usarse en la transmisión de al menos una señal adicional al por lo menos un dispositivo inalámbrico.
