Abstract
Las realizaciones proporcionan una conformación de haces en tierra con pasarelas espacialmente multiplexadas, mutuamente sincronizadas en un sistema de comunicaciones inalámbricas. Algunas realizaciones operan en el contexto de un satélite que tiene una antena de conexión de haz enfocado que se comunica con múltiples terminales de pasarela distribuidos geográficamente (p. ej., una pasarela única por haz) y una antena de usuario que proporciona comunicaciones con los terminales de usuario a través de haces de usuario conformados. Los terminales de pasarela pueden comunicar señales de conexión que son de haz ponderado y están mutuamente sincronizadas en fase (p. ej., de acuerdo con satélites y/o balizas de bucle de retorno). Por ejemplo, La sincronización puede permitir que las señales del enlace ascendente directo se reciban sincronizadas en fase por el satélite, y la ponderación de haz puede permitir que las señales del enlace descendente directo se combinen espacialmente para conformar haces de usuario directos. Las realizaciones pueden lograr una reutilización extensa del ancho de banda mediante la multiplexación espacial mutuamente sincronizada de las comunicaciones del enlace de conexión.
