本申请实施例中的终端设备可以包括具有无线通信功能的手持式设备、车载设备、可穿戴设备或计算设备。示例性地，UE可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、可穿戴设备、车载设备等，本申请实施例对此并不限定。
本申请实施例中的接入网设备可以是用于与终端设备通信的设备，可以有多种形式，比如宏基站、微基站、中继站和接入点等，该接入网设备可以是新空口(new radio，NR)中的基站，其中，5G NR中的基站还可以称为发送接收点(transmission reception point，TRP)或下一代节点B(next generation Node B，gNB)，也可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)中的基站收发台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的节点B(nodeB，NB)，还可以是长期演进(long term evolution，LTE)系统中的演进型节点B(evolutional Node B，eNB或eNodeB)，或者下一代通信系统中的基站，比如6G的基站。
在本申请实施例中，终端设备或接入网设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或接入网设备，或者，是终端设备或接入网设备中能够调用程序并执行程序的功能模块。

图1是现有技术中的一种定位方法和设备的通信系统的示意性架构图。如图1所示，该系统100包括接入网设备110和终端设备120。
接入网设备110测得的AOA得到终端设备120所处的方向，再接入网设备110根据测量终端设备120的上行传输来确定时间提前量(timing advance，TA)，从而可得到终 端设备120和接入网设备110之间的距离：
D＝0.5×TA×c
其中D表示终端设备120到接入网设备110之间的距离，TA表示时间提前量，c表示光速。
最后根据AOA和D的测量值实现对终端设备120的定位。
NR协议中规定下一代演进型节点(next-generation evolutional Node B，ng-eNB)支持对终端设备的AOA测量，测得AOA以正北方向为法线方向，逆时针方向为正。TA可以通过终端设备和ng-eNB联合测量得到，也可以通过ng-eNB单独测量得到。该AOA+TA定位方法使用单站即可实现定位，且当终端设备不支持定位功能时仍能实现定位。
图2是一种AOA+TA定位技术的示意性流程图。
210，定位管理单元向接入网设备发送定位请求。相应的，该接入网设备接收来自于该定位管理单元的定位请求。定位请求中包含对测量的请求和测量时间的规定。该定位管理单元与该接入网设备可以通过附加新空口定位协议(NR positioning protocol annex，NRPPa)进行通信。
220，接入网设备对终端设备进行测量，所述测量通过无线资源控制测量过程(radio resource control measurement procedure，RRC Measurement Procedure)实现。
230，接入网设备将测量结果发送给定位管理单元，相应的，定位管理单元接收来自接入网设备发送的测量结果。测量结果包括AOA和TA等测量值。若测量失败则返回失败信息。
AOA+TA定位技术的定位误差较大，仅适用于近距离或精度要求不高的场合。当接入网设备和终端设备距离较远时，即使存在微小的AOA测量误差也会因为较远距离而造成较大的定位距离偏差。
另一种定位方法是利用天线阵列进行到达角位置计算。在该方法中，可能由于天线阵元间隔不理想使得天线旁瓣过大，从而导致角度估计不准的问题。理论研究中，当天线阵元间隔d为接收信号波长λ的一半时，则不存在旁瓣过大而错误估计的角度值的问题。
以采用离散傅里叶变换(Discrete Fourier Transform，DFT)法估计入射角为例，图3示出了当天线阵元间隔为λ/2理想值时，DFT法生成的谱计算出的角度信息为唯一解。在实际工程中，往往不能保证天线阵元间隔为λ/2理想值，实际的间隔可能大于λ/2。图4和图5示出了天线阵元间隔为0.8λ和1λ时，对同一入射角，采用DFT法生成的谱分别出现两个峰值，每张谱图中两个峰值的其中一个属于旁瓣引起的错误估计值。
也就是说，当天线阵元间隔大于λ/2理想值时，针对一个测量对象可能估计出多个测量值，如果只选择一个测量值上报，可能会选择错误的值，而目前没有相应的角度选择方案。
本申请提供了一种发送角度测量结果的方法和设备，支持针对一个测量对象，上报多个角度测量值，可以减少当天线阵元间隔大于λ/2理想值时导致的角度测量值选择错误的问题。
图6是应用本申请实施例的用于定位终端设备的一个定位系统的架构示意图。如图6所示，该定位系统中，终端设备通过LTE-Uu和/或NR-Uu接口分别经由ng-eNB和gNB连接到无线接入网；无线接入网通过NG-C接口经由接入和移动管理功能(access and  mobility management function，AMF)单元连接到核心网。其中，下一代无线接入网(next-generation radio access network，NG-RAN)包括一个或多个ng-eNB；NG-RAN也可以包括一个或多个gNB；NG-RAN还可以包括一个或多个ng-eNB以及gNB。ng-eNB和gNB之间通过Xn接口进行通信。ng-eNB为接入5G核心网的LTE接入网设备，gNB为接入5G核心网的5G接入网设备。核心网包括AMF与LMF(或演进服务定位中心(evolved serving mobile location center，E-SMLC))等单元。其中，AMF用于实现接入管理等功能，LMF(或E-SMLC)用于实现定位等功能。AMF与LMF之间通过NLs接口连接。LMF是一种部署在核心网中为终端设备提供定位功能的装置或组件。
图7是应用本申请实施例的用于定位终端设备的另一个定位系统的架构示意图。图7与图6的定位系统架构的区别在于，图7的定位管理组件(location management component，LMC)部署在gNB中，LMC可承担LMF的一部分功能，gNB不需要将测量结果上报至核心网，节省了信令开销，降低了定位时延。
在本申请实施例中，定位功能节点(比如E-SMLC或LMF)通过收集接入网设备上报的测量信息，以确定终端设备的位置。可选地，接入网设备和E-SMLC之间的交互通过LPPa协议实现，接入网设备和LMF之间的交互通过NRPPa协议实现。
应理解，上述图6或图7的通信系统中，可以包括一个或多个gNB，单个或多个终端设备。单个gNB可以向单个终端设备或多个终端设备传输数据或控制信令。多个gNB也可以同时为单个终端设备传输数据或控制信令。
还应理解，上述图6或图7的通信系统中包括的设备或功能节点只是示例性地描述，并不对本申请实施例构成限定，事实上，图6或图7的定位系统中还可以包含其他与图中示意的设备或功能节点具有交互关系的网元或设备或功能节点，这里不作具体限定。
图8示出了本申请提供的一种发送角度测量结果的方法300的示意性流程图。如图8所示，所述方法300包括：
S310，第一设备向第二设备发送参考信号。相应地，该第二设备接收来自该第一设备的该参考信号。
可选地，第一设备可以为终端设备或者用于终端设备的部件(例如芯片或电路等)，第二设备可以为接入网设备或者用于接入网设备的部件(例如芯片或电路等)，接入网设备可以对不同的终端设备，或者同一终端设备的不同参考信号，或者同一参考信号的不同传播路径进行测量。
可选地，第一设备可以为接入网设备或者用于接入网设备的部件(例如芯片或电路等)，第二设备可以为终端设备或者用于终端设备的部件(例如芯片或电路等)。
本申请实施例中的参考信号是指包含第一设备定位信息的参考信号，本申请实施例中统一记作“参考信号”，但不能理解为该“参考信号”仅包括探测参考信号SRS，以下不再赘述。可选地，参考信号包括但不限于定位参考信号(positioning reference signal，PRS)、解调参考信号(de-modulation reference signal,DMRS)、跟踪参考信号(tracking reference signal,TRS)、信道状态信息参考信号(channel state information reference signal,CSI-RS)。
S320，所述第二设备对所述参考信号进行测量，得到第一角度测量结果，所述第一角度测量结果是第一测量对象的测量结果，所述第一测量对象为直射径或反射径，所述第一角度测量结果包括M项角度测量量，所述第一角度测量结果中的M项角度测量量中的至 少一项测量量包括多个角度测量值，M为大于或等于1的正整数。
可选地，所述第二设备对所述参考信号进行测量，得到第二角度测量结果，所述第二角度测量结果是第二测量对象的测量结果，第二测量对象与第一测量对象不同。例如第一测量对象为直射径，第二测量对象为反射径；又如第一测量对象为反射径，第二测量对象为直射径；又如，第一测量对象为反射径，第二测量对象是不同于第一测量对象的另一个反射径。
可选地，直射径可以为一条，反射径可以为多条。例如，对于第一设备，包含第一直射径、第一反射径、第二反射径、第三反射径，第一测量对象和第二测量对象可以是第一直射径、第一反射径、第二反射径、第三反射径中的任意两个测量对象。按照本申请实施例的方法，第二设备可以测量第一设备的任意多个测量对象。
可选地，第二设备接收到的参考信号可以是第一设备通过直射径发送，也可以是第一设备通过反射径发送。
对于一个测量对象，角度测量结果可以包括以下角度测量量中的任意M个，M为大于1或等于1的正整数：水平入射角、垂直入射角、天线横向阵列入射角、天线纵向阵列入射角。其中，水平入射角指的是入射方向投影到水平面与正北方向的夹角；垂直入射角指的是入射方向与水平面的夹角，或入射方向与天顶方向的夹角；天线横向阵列入射角指的是入射方向与天线阵列(行)的夹角；天线纵向阵列入射角指的是入射方向与天线阵列(列)的夹角。图13为天线横向阵列入射角和天线纵向阵列入射角的示意图。所述天线横向阵列入射角和天线纵向阵列入射角是指，将天线阵列看做一个长方形，天线阵列横向(行)为长方形的长，天线阵列纵向(列)为长方形的宽，则当参考信号到达天线阵列时，入射方向与长方形的长的夹角α为天线横向阵列入射角，入射方向与长方形的宽的夹角β为天线纵向阵列入射角。
对于M个角度测量量中的每一个角度测量量，当天线阵元间隔等于λ/2理想值时，每个角度测量量的角度测量值是一个；当天线阵元间隔大于λ/2时，每个角度测量量的角度测量值为多个，例如可以是两个、三个或者更多。
应理解，当每个角度测量量的角度测量值是一个时，该角度测量值即定位管理单元需要用于终端设备定位计算的目标角度测量值；当每个角度测量量的角度测量值为多个时，仅有一个角度测量值是定位管理单元需要用于终端设备定位计算的目标角度测量值。
S330，第二设备将角度测量结果发送至定位管理设备，所述角度测量结果可以是第一角度测量结果和/或第二角度测量结果。相应地，定位管理设备接收来自于第二设备的角度测量结果。
第二设备发送M个角度测量量的角度测量值时可按照如下方式：
方式一，gNB每次向LMF发送M组角度测量值，M组角度测量值对应的角度测量量为水平入射角、垂直入射角、天线横向阵列入射角和天线纵向阵列入射角中的任意M个。如，M为4，每组角度测量值均为2个时，角度测量结果可按如下方式上报：
水平入射角 [测量值1，测量值2]
垂直入射角 [测量值1，测量值2]
天线横向阵列入射角 [测量值1，测量值2]
天线纵向阵列入射角 [测量值1，测量值2]
应理解，每组角度测量值可能为多个，可能为1个，可能为0个。
方式二，gNB每次向LMF发送M组角度测量值，M组角度测量值对应的角度测量量为水平入射角、垂直入射角、天线横向阵列入射角和天线纵向阵列入射角中的任意M个。设置gNB将M组角度测量值按照默认顺序排列，作为示例而非限定，可设置默认排列顺序如表1所示：
表1角度测量值上报顺序
Figure PCTCN2019109197-appb-000001
默认M组角度测量值按照水平入射角的角度测量值、垂直入射角的角度测量值、天线横向阵列入射角的角度测量值、天线纵向阵列入射角的角度测量值，每组角度测量值包括两个角度测量值，没有相应的角度测量值则填充0。如表1所示，则该次上报的角度测量值为：第1、2个为水平入射角的角度测量值，第3、4个为垂直入射角的角度测量值，第5、6个为天线横向阵列入射角的角度测量值，但天线阵元间隔恰好等于λ/2理想值，因此只有角度测量值5，而天线纵向阵列入射角没有测相应的角度测量值。
方式三，gNB每次向LMF发送一组角度测量值，该组角度测量值对应的角度测量量为水平入射角、垂直入射角、天线横向阵列入射角和天线纵向阵列入射角中的任一个。可选地，S330之前还包括：
S331，gNB向LMF发送配置信息，对应地，LMF接收来自gNB的配置信息，配置信息用于指示gNB接下来向LMF发送的角度测量值属于哪一个角度测量量，如水平入射角、垂直入射角、天线横向阵列入射角和天线纵向阵列入射角中的任一个。LMF可以基于gNB发送的配置信息，确定接下来接收到的角度测量值属于哪一个角度测量量。例如，配置信息指示为水平入射角，则LMF在接收到多个角度测量值后，可以确定多个角度测量值都是水平入射角的角度测量结果。
S340，定位管理设备根据角度测量结果确定第一设备位置。
可选地，定位管理设备接收到来自第二设备发送的角度测量结果后，可以采用粒子群优化(particle swarm optimization，PSO)算法进行定位。具体地，建立初始化粒子群，包括随机位置。根据适应函数，评价每个粒子的适应度。对每个粒子，将其当前适应值与其个体历史最佳位置对应的适应值作比较，如果当前适应值更高，则用当前位置更新历史最佳位置。对每个粒子，将其当前适应值与全局最佳位置对应的适应值作比较，如果当前的适应值更高，则用当前的位置更新全局最佳位置。如此更新每个粒子的位置。当算法达到最大迭代次数或者最佳适应值的增量小于某个给定的阈值时算法停止。此时对应的第一设备位置为PSO算法计算的第一设备位置。可选地，如果是多站联合角度定位，可以将直射径对应的角度测量结果代入PSO算法，确定第一设备的位置。可选地，每个角度测量对象的多个角度测量量，例如水平入射角和垂直入射角都可以代入PSO算法，从而实现对第一设备的三维定位。
可选地，定位管理设备接收到来自第二设备发送的角度测量结果后，可以采用加权方法进行定位。具体地，角度测量结果中，每个角度测量量包含多个角度测量值，例如，包含两个角度测量值，则第一个角度测量值α的权重为a，第二个角度测量值β的权重为b，其中a+b＝1，计算出的目标角度值γ即为信号入射角。则γ＝aα+bβ。或者，包含三个角度 测量值，则第一个角度测量值α的权重为a，第二个角度测量值β的权重为b，第三个角度测量值δ的权重为c，其中a+b+c＝1，目标角度值γ为信号入射角，则γ＝aα+bβ+cδ。
