Abstract

Se Proporciona la formación de haces utilizando una disposición de antenas configurada para transmitir a través de un sector angular. Un primer conjunto de puertos de antena virtual se determina por un mapeo de puertos de antena física de la disposición de antenas, el primer conjunto de puertos de antena virtual define un patrón de haces. Un primer conjunto de señales de referencia para adquirir información de estado de canal se transmite sobre el primer conjunto de puertos de antena virtual. Se adquiere la información angular sobre un dispositivo transceptor inalámbrico que recibe el primer conjunto de señales de referencia. El patrón de haces se adapta con base en una precisión de la información angular y/o la información angular en sí misma.
