在一示例性实施方式中，基站还可以执行S203。
S203、基站接收终端反馈的F个信道状态信息。
信道状态信息可以包括以下至少之一的参数：RI、CRI、PMI、LI、CQI。
由于N个波束信息是相邻的，因此F个信道状态信息有一定的相关性。比如以下至少之一：两个PMI对应的预编码距离小于一个门限值a1，两个PMI对应的预编码相关性大于某个门限值a2，两个RI对应的索引差的绝对值小于门限值a3，两个CQI对应的索引差绝对值小于门限值a4，这里，a1、a2、a3、a4为正实数。
S204、基站根据F个信道状态信息以及K个位置信息，获取L个新的信道状态信息。其中，N、K、F、L为大于或等于1的整数。
比如，通过位置信息，预测未来UE可能的运行轨迹，从而获得未来L个位置信息，通过所述L个位置信息确定基站和终端的L个方向信息，从而根据这L个方向信息拟合出新的L个预编码矩阵，以及新的L个CRI、CQI。
基站可以采用所述新的L个信道状态信息对终端进行资源调度和波束管理。
一些示例如下：通过K个位置信息获取这K个位置信息的地理坐标，并根据地理坐标通过人工智能的深度学习算法拟合出L个新的地理位置信息，比如通过线性拟合(或加权拟合)的方法，或者通过深度学习的方式研究位置间的相关性，从而根据这些位置的相关性得到L个新的地理位置，并利用所述L个新的地理位置信息和本文前面的实施例的方法获得的L个波束信息，利用所述的L个波束信息和/或接收的N个波束信息一起确定未来一段时间的波束管理使用的波束。或者，根据所述的L个波束信息和/或接收的N个波束信息获得L个新的预编码矩阵，比如，所述预编码矩阵对应的同一个极化方向天线对应的矢量与所述的波束信息对应的矢量的相关性大于某个门限值或者距离小于门限值 的码字。并可以利用新的L个预编码矩阵计算新的CQI、RI等信息，从而利用新的L个CSI和/或N个接收的CSI对用户进行资源分配以及优先级调度。一个应用场景比如在高速公路或者铁路上移动的用户，由于运动轨迹是近乎直线的，只要知道移动速度和/或加速度就可以推测下K个时刻的位置信息；从而可以根据这些位置信息获得基站与终端的波束方向信息，从而根据可以根据波束方向信息确定CSI信息。
