Abstract

La presente invención proporciona un método para determinar un número de bits de Rl de indicación de jerarquía, una estación base, y una terminal. El método incluye: determinar, por medio de una estación base, información de indicación de acuerdo con una correspondencia entre una terminal y la estación base y una capacidad de múltiple entrada múltiple salida MIMO de la terminal, donde la información de indicación incluye información utilizada por la terminal para determinar un número de bits ocupados para enviar una Rl; y enviar, por medio de la estación base, la información de indicación a la terminal, de manera que la terminal determina, de acuerdo con la información de indicación, el número de bits ocupados para enviar la Rl. En la presente invención, el UE y la estación base acuerdan sobre el entendimiento del número de bits ocupados por la información de Rl.
