Abstract

Modalidades de la presente invención se refieren a un método de estimación de canal, una estación base, equipo de usuario (UE), y un sistema. El método incluye: configurar, por una estación base, una conexión a equipo de usuario (UE); y enviar, al UE, información de notificación que indica que el UE está en un escenario remoto de radio, donde la información de notificación se utiliza para instruir al UE para llevar a cabo estimación de canal al utilizar un algoritmo de estimación de canal aplicable al escenario remoto de radio, y el algoritmo de estimación de canal se utiliza para llevar a cabo estimación de canal en una señal que se obtiene después de que se superponen señales de enlace descendente de múltiples unidades remotas de radio (RRU). El UE puede llevar a cabo estimación de canal al utilizar el algoritmo de estimación de canal apropiado, para mejorar efectivamente la precisión de la estimación de canal, mejorando así efectivamente un rendimiento de datos de enlace descendente del UE.
