Abstract

Se describe un método y aparato de configuración de matriz de precodificación basados en reciprocidad del canal. El método incluye: en la transmisión de enlace descendente, un lado de la red envía por separado, en cada puerto de antena asociado con cada capa de transmisión, CSI-RS sujeto a formación de haces a un terminal mediante el uso de haces calculados de acuerdo con la información de ángulo y la información de retardo determinada con base en información de estado del canal de enlace ascendente, y determina una matriz de precodificación para la transmisión de enlace descendente del terminal de acuerdo con los haces enviados en los puertos de antena K0 seleccionados por el terminal con base en CSI-RS, y un conjunto de coeficientes de combinación de haces.
