Abstract

La presente invención describe un método para transmitir una matriz de precodificación de cuatro antenas, un equipo de usuario, y una estación base. El método incluye: determinar un rango utilizado para indicar el número de capas de transmisión; determinar una primera matriz de precodificación en un conjunto de libro de códigos correspondiente al rango; determinar una primer PMI y un segundo PMI utilizadas para indicar la primera matriz de precodificación; y enviar el primer PMI y del segundo PMI utilizadas para indicar la primera matriz de precodificación a una estación base. Por medio del método para transmitir una matriz de precodificación de 4 antenas, el equipo de usuario, y la estación base de acuerdo con modalidades de la presente invención, más matrices de precodificación que son aplicables a una antena de arreglo lineal uniforme pueden estar indicadas sin cambiar un modo de retroalimentación o bits de retroalimentación, y se puede asegurar que el desempeño para la aplicación de una antena de doble polarización no se ve afectada, de manera que el desempeño del sistema se puede mejorar y la experiencia del usuario puede ser mejorada.
