Abstract

本发明实施例提供一种信道空间特征信息获取方法及基站，该方法包括：第一基站分别向多个第二基站发送信道空间特征请求和待测量用户设备UE的标识，其中所述信道空间特征请求用于指示所述第二基站对所述待测量UE进行信道空间特征信息测量；第一基站接收所述多个第二基站发送的信道空间特征指示信息，信道空间特征指示信息中携带待测量UE的信道空间特征信息。本发明实施例中，第一基站、第二基站与UE通信的信道都可以获取信道空间特征信息，能够更好地分辨不同角度或方向的多径，从而利用这种优势进行数据传输，这样也实现了在数据传输过程中更好地避免多用户之间的干扰，很好地将Massive MIMO技术应用到多基站协作与UE通信的系统中。
