Abstract
El canal de retorno en un sistema de comunicación de múltiple entrada y múltiple salida (MIMO) se utiliza para proporcionar información de señal sobre una base de canal individual. En una modalidad, en un ambiente de fábrica controlado, esa información puede utilizarse para incrementar hacia arriba o hacia abajo el amplificador de ganancia variable y/o el amplificador de potencia de un transmisor de MIMO y/o un receptor para generar una configuración de potencia de señal por defecto para utilizarse durante la operación normal. Después de esto, tal información de señal puede proporcionarse similarmente mediante el canal de retorno y utilizarse para ajustar adicionalmente los parámetros de transmisión para justificar las condiciones de señal de ubicación específica.
