    • A method according to the present invention is for selecting User Equipment (UE) for scheduling/precoding within the coverage area of a communications node having a predefined codebook. The method includes: receiving at the communications node feedback information from each of the UEs within the coverage area of the communications node wherein the feedback information includes at least one precoder matrix indicator (PMI); generating at the communications node a precoder matrix based on the reported precoder matrix indicator from each UE; determining at the communications node correlation values for each UE in the coverage utilizing the precoder matrix; identifying a pair of UEs having minimum correlation values; and selecting the identified UEs for scheduling/precoding if the minimum correlation value is less than or equal to a threshold value.
    • 根据本发明的方法是用于选择在具有预定码本的通信节点的覆盖区域内进行调度/预编码的用户设备(UE)。 该方法包括:在通信节点处从通信节点的覆盖区域内的每个UE接收反馈信息,其中反馈信息包括至少一个预编码器矩阵指示符(PMI); 在所述通信节点处根据来自每个UE的报告的预编码器矩阵指示符在所述通信节点处生成预编码器矩阵; 在所述通信节点处使用所述预编码器矩阵来确定所述覆盖中的每个UE的相关值; 识别具有最小相关值的一对UE; 以及如果最小相关值小于或等于阈值,则选择所识别的UE进行调度/预编码。
