Abstract
Se describen los sistemas y métodos para estimar una o más propiedades de canal de un enlace descendente de una red de comunicaciones celular con base en puertos de antena cuasi co-localizados con respecto a la una o más propiedades del canal. En una modalidad, un dispositivo inalámbrico recibe una subtrama de enlace descendente que incluye un canal de control de enlace descendente de la red de comunicaciones celular. El dispositivo inalámbrico estima una o más propiedades de canal en gran escala para un puerto de antena que interese en el canal de control de enlace descendente con base en una subserie de señales de referencia que corresponde a los puertos de antena de la red de comunicaciones celular que están cuasi co-localizados con el puerto de antena que interesa, con respecto a la una o más propiedades del canal en gran escala. Como resultado de utilizar puertos de antena cuasi co-localizados, se mejora considerablemente la estimación de la una o más propiedades de canal en gran escala.
