Abstract
La presente divulga un método para transmitir una matriz de precodificación de cuatro antenas, un equipo de usuario y una estación de base. El método incluye: determinar un rango usado para indicar la cantidad de capas de transmisión; determinar una primera matriz de precodificación de un conjunto de libros de códigos correspondiente al rango; determinar un primer PMI y un segundo PMI usados para indicar la primera matriz de premodificación y enviar el primer PMI y el segundo PMI usados para indicar la primera matriz de precodificación a una estación de base. Por medio del método para transmitir una matriz de precodificación de cuatro antenas, el equipo de usuario y la estación de base de acuerdo con las formas de realización de la presente pueden indicarse más matrices de precodificación que son aplicables a una antena de arreglo lineal uniforme sin cambiar un modo de realimentación o los bits de realimentación, y puede asegurarse que no se vea afectado el rendimiento de la aplicación de una antena doble polarizada, de manera que puede mejorar el rendimiento del sistema y ampliarse la experiencia del usuario.
