Abstract
Se divulga un método de un primer punto de acceso y un punto de acceso dispuesto para proporcionar acceso de comunicación inalámbrica para un sistema de comunicación inalámbrica. El método comprende determinar que una primera estación debe transmitir datos de enlace ascendente en una transmisión de enlace ascendente en una primera banda de frecuencia en el espectro sin licencia, asignar un segundo punto de acceso para recibir la transmisión de enlace ascendente, en donde el segundo punto de acceso cubre al menos un área superpuesta con un área de cobertura del primer punto de acceso, determinar una segunda estación destinada a la transmisión de enlace descendente, en donde la transmisión de enlace descendente está programada para transmisión al menos parcialmente simultánea con la transmisión de enlace ascendente desde la primera estación y al menos parcialmente superpuesta a la primera banda de frecuencia, en donde una selección de la segunda estación destinada a la transmisión de enlace descendente se basa en una relación espacial entre la primera y la segunda estación, asignando ponderaciones de antena para un arreglo de antenas del primer punto de acceso para proporcionar transmisión de formación de haces de la transmisión de enlace descendente hacia la segunda estación y un nulo hacia el segundo punto de acceso, y transmitir la transmisión de enlace descendente utilizando las ponderaciones de antena. El punto de acceso está dispuesto para realizar el método.
