Abstract

一种数据降维方法、装置及系统、计算机设备及存储介质，涉及通信领域，所述方法包括：接收天线域接收信号(201)，所述天线域接收信号包括RRS对应的阵列天线接收到的用户设备UE发送的上行信号，所述天线域接收信号为时域信号，所述天线域接收信号的维度为N1，所述N1为大于1的整数；获取接收波束权值，所述接收波束权值是根据所述UE的信道信息确定的，其中，根据不同的信道信息确定的接收波束权值不同(202)；采用所述接收波束权值对所述天线域接收信号进行降维，得到波束域接收信号(203)，波束域接收信号为频域信号，波束域接收信号的维度为N2，0＜N2＜N1。所述方法解决了相关技术中数据降维的灵活性较低的问题。
