Abstract

Se divulga un método y sistema para coordinar el uso de formación de haz entre dos entidades en comunicación en un sistema de comunicación inalámbrica. Las dos entidades pueden comunicar información de control referida su uso respectivo de formación de haz. Se provee un factor de corrección para al menos una entidad donde dicha entidad puede reducir o retener su ajuste de haz para corregir cualquier error medido en la alineación de su haz con respecto al haz de otra entidad con la que está en comunicación. Se seleccionan parámetros de ajuste para ajustar los haces en base a condiciones que rodean la comunicación.
