定位移动终端的方法和装置
摘要：
本发明公开一种定位UE的方法，包括：多次测量UE信号的到达角AOA和UE信号到达基站的时延；对测量获得的多个AOA进行计算获得AOA的中间值；对测量获得的多个时延进行计算获得时延的中间值；估算所述UE所处环境的非直射因子；利用所述AOA的中间值、所述时延的中间值、所述非直射因子和UE所在基站的位置信息计算所述UE的位置。在本发明中，在估算UE和基站之间的距离时对估算的距离进行修正，也就是对UE信号到达基站的时延进行修正，从而减小UE信号到达基站的时延和真实值之间的偏差。当UE处于非直射环境时，采用本发明提供的技术方案可以有效地提高对UE的定位精度。本发明还公开一种定位UE的装置。
摘要（英）：

The present invention discloses a method for positioning UE, wherein the method comprises the following steps: measuring the angle-of-arrival AOA of UE signal and time delay of UE signal to the base station for a plurality of times; calculating the plurality of AOAs obtained by measuring for obtaining the intermediate value of AOA; calculating the plurality of time delays obtained by measuring for obtaining the intermediate value of time delay; estimating the non-perpendicular factor of environment of UE; and computing the position of UE according to the intermediate value of AOA, the intermediate value of time delay, the non-perpendicular factor and the position information of base station comprising the UE. The estimated distance is modified when the distance between UE and base stationis estimated in the invention, namely the time delay of UE signal to the base station is modified thereby reducing the time delay of UE signal to the base station and the deviation to the real value.When the UE is in the non-perpendicular environment, the technical plan provided by the invention can effectively increase the positioning precision to UE. The invention also discloses a device for positioning UE.
