Abstract: The disclosure provides a downlink transmission method and an eNodeB in a multiple input multiple output system. The method includes: obtaining channel quality indication of a User Equipment (UE) to generate a channel condition indication value; obtaining channel rank indication of the UE to generate a channel correlation indication value; obtaining uplink channel impulse response estimation data of the UE to generate a channel variation state indication value; selecting a downlink transmission mode according to the channel condition indication value, the channel correlation indication value and the channel variation state indication value; transmitting data to the UE in the selected downlink transmission mode. Because of extracting information from a current channel as a basis of a subsequent selection of the downlink mode, the disclosure can greatly improve a resource utilization ratio of a system and realize a better wireless transmission effect.
Abstract translation: 本公开提供了在多输入多输出系统中的下行链路传输方法和eNodeB。 该方法包括：获取用户设备（UE）的信道质量指示，生成信道状态指示值; 获取所述UE的信道秩指示以产生信道相关指示值; 获取所述UE的上行链路信道脉冲响应估计数据，以产生信道变化状态指示值; 根据信道条件指示值，信道相关指示值和信道变化状态指示值选择下行链路传输模式; 在选择的下行链路传输模式下向UE发送数据。 由于从当前信道中提取信息作为后续选择下行链路模式的基础，本发明可以大大提高系统的资源利用率并实现更好的无线传输效果。
