Abstract

Se proporcionan mecanismos para la administración de haces. Un método lo lleva a cabo un nodo de red. El método comprende llevar a cabo un procedimiento de administración de haces para dispositivos terminales servidos por el nodo de red. El método comprende transmitir, durante una primera parte del procedimiento de administración de haces, una señal de referencia para permitir que cada uno de los dispositivos terminales que participe en el procedimiento de administración de haces identifique en qué haz de un primer conjunto de haces, en el que la señal de referencia se transmite desde el nodo de red, la señal de referencia se recibe con la más alta potencia recibida. El método comprende transmitir, durante una segunda parte del procedimiento de administración de haces, la señal de referencia para permitir que cada uno de los dispositivos terminales identifique en qué haz de un segundo conjunto de haces, en el que se recibe la señal de referencia desde el nodo de red por los dispositivos terminales, la señal de referencia se recibe con la más alta potencia recibida. El método comprende transmitir, durante una tercera parte del procedimiento de administración de haces, la señal de referencia para permitir a cada uno de los dispositivos terminales que participe en el procedimiento de administración de haces identificar para qué haz en un tercer conjunto de haces, en el que la señal de referencia se transmite desde el nodo de red, la señal de referencia se recibe con la más alta potencia recibida. Hay un tercer conjunto respectivo de haces para cada haz respectivo en el primer conjunto de haces. La tercera parte del procedimiento de administración de haces se lleva a cabo para cada respectivo tercer conjunto de haces. La segunda parte se lleva a cabo antes que la tercera parte al menos para uno de los respectivos terceros conjuntos de haces.
