目前LTE和NR Rel-16的定位是基于核心网定位管理功能(location management function，LMF)控制，接入网和终端辅助的架构。
在该定位架构下，以下行定位为例，LMF主要完成以下操作：
(1)与ng-eNB/gNB之间的小区信息交互，例如获取定位参考信号(positioning reference signal，PRS)、探测参考信号(sounding reference signal，SRS)配置信息、小区 定时、小区位置信息等。
(2)与UE之间完成UE能力信息传递、辅助信息传递、测量信息传递等。
(3)与gNB之间完成测量信息传递等。
基于小区信息、UE对各小区下行信号的测量上报、各小区对UE上行信号的测量上报，例如以下定位技术中，LMF可以确定UE的位置信息：
下行链路到达时间差(downlink-time difference of arrival，DL-TDOA)定位技术：UE对各小区PRS信号测量参考信号到达时间差(reference signal time difference，RSTD)，并将测量结果上报给LMF。
上行链路到达时间差(uplink-time difference of arrival，UP-TDOA)定位技术：各小区对UE的SRS信号测量上行链路相对到达时间(uplink-relative time of arrival，UL-RTOA)，并将测量结果上报给LMF。
下行离开角(downlink-angle of departure，DL-AoD)定位技术：UE对各小区PRS信号测量定位参考信号接收功率(positioning reference signal-reference signal received power，PRS-RSRP)，并将测量结果上报给LMF。
上行到达角(uplink-azimuth angle of arrival，UL-AoA)定位技术：各小区对UE的SRS信号测量AoA/俯仰角(Zenith angle of arrival,ZoA)，并将测量结果上报给LMF。
增强的基于小区ID(enhanced cell identity，E-CID)定位技术：UE对各小区同步信号块(synchronization signal and physical broadcast channel block，SSB)测量同步信号参考信号接收功率(synchronization signal-reference signal received power，SS-RSRP)/同步信号参考信号接收质量(synchronization signal-reference signal received quality，SS-RSRQ)/同步信号参考信号与干扰加噪声比(synchronization signal-signal to interference plus noise ratio，SS-SINR)，并将测量结果上报给LMF。
多往返时间(multi-round trip time，Multi-RTT)定位技术：UE对各小区PRS信号测量UE收发时间差(Rx-Tx time difference)，并将测量结果上报给LMF；各小区对UE的SRS信号测量gNB Rx-Tx time difference，并将测量结果上报给LMF。
下面以UL-AoA定位技术为例，具体介绍一下该定位技术。
UL-AoA定位技术的具体方法是终端设备发送SRS，服务小区基站和邻区基站接收SRS。当基站接收天线具有阵列形式时，所发射的信号通过天线阵列时，由于阵列中的每根天线与发射设备之间的距离不同，接收设备会出现信号相位差。基站可以根据多个天线阵元之间因为波程差造成的相移估计相对信号所在方向，从而确定终端相对所在方向。
如图2所示，例如设基站天线间距为dλ，其中λ为载波波长，终端设备发送的SRS在基站接收时的来波方向与天线阵列夹角为
Figure PCTCN2019119114-appb-000001
相邻天线阵元之间的波程差为kλ，其中
Figure PCTCN2019119114-appb-000002
从而相邻天线阵元上的信号到达时间差kλ/c＝k/f c，其中c为光速，f c为载波频点。对于无线射频信号
Figure PCTCN2019119114-appb-000003
其中，x BB(t)为基带信号。在此基础上，射频信号的时延k/f c等效于引入额外相位，如下所示。
Figure PCTCN2019119114-appb-000004
这里
Figure PCTCN2019119114-appb-000005
是因为时延k/f c对基带信号而言影响可以忽略不计。从而可以确定不同天线阵元之间信号相位差为
Figure PCTCN2019119114-appb-000006
角度定位的原理是通过获取基站上行接收端在不同天线阵元之间的相位差，反过来估计出来波方向
Figure PCTCN2019119114-appb-000007
为了刻画空间角度，第三代合作伙伴计划(3rd generation partnership project，3GPP)定义了方向角和俯仰角。方向角(AoA)定义为终端设备在水平面与地理正北方向的夹角，以逆时针旋转为正，如图3中φ所示；俯仰角(ZoA)定义为终端设备所在方向与穹顶方向夹角，如图3中θ所示。
图2所示的天线为一维阵列，当实际为2维阵列时，不失一般地，假定2维天线阵列位于地理正北与穹顶方向确定的平面内，如图4所示水平维度天线阵元间距为d 1λ，垂直维度天线阵元间距为d 2λ，容易求得水平/垂直阵元与基于图3确定的俯仰角与方向角、图4中d 1、d 2的关系为
Figure PCTCN2019119114-appb-000008
Figure PCTCN2019119114-appb-000009
通过测量取得k 1和k 2，可以反解求得θ和φ。当基站有其他朝向时，为了求得θ和φ还需要考虑基站朝向与图4所示朝向之间的旋转。
现有基于角度定位方案是基站估计出终端的角度，并且基于基站绝对坐标，由多个基站联合确定出终端位置。
由于角度定位存在一定误差，并且误差会随着终端设备与基站距离增大而增大，所以用于车联网这种对位置精度要求较高的场景中误差较大，无法精准的确定两车相对位置关系。
有鉴于此，本申请提出一种方法，对终端设备的定位方法进行优化，可以更加准确的定位终端设备的位置。
下面将结合附图详细说明本申请提供的各个实施例。
作为示例而非限定，本申请所有实施例中的网络设备可以为RAN，如下一代无线接入网(next-generation radio access network，NG-RAN)。
