Abstract

Se proveen mecanismos para la selección de haz. Un primer dispositivo transceptor de radio realiza un método donde el método comprende obtener estimaciones de calidad de enlace de una señal de radio comunicada al primer dispositivo transceptor de radio desde un segundo dispositivo transceptor de radio por medio de al menos un primer haz tomado de un primer conjunto de haces y un segundo haz. El segundo haz es más ancho que el primer haz. El método comprende seleccionar cuál del primer haz y del segundo haz se utiliza para las comunicaciones continuas de señales de radio con el segundo dispositivo transceptor de radio de acuerdo con una comparación entre las estimaciones de calidad de enlace del primer haz y las estimaciones de calidad de enlace compensadas del segundo haz.
