Description

用于终端设备定位的方法、装置及系统
本申请要求于2018年1月5日提交中国国家知识产权局、申请号为201810011910.8、发明名称为“用于终端设备定位的方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及通信系统中的终端设备的定位技术。
背景技术
随着通信技术的发展和移动设备越来越高的普及，人们对自身位置的定位服务需求日益激增。随着自动驾驶，智慧城市，物联网等新兴产业的出现，通信技术也越来越多地与这些垂直行业进行融合，这些垂直行业也带来了对于定位的需求。在原先的长期演进(Long Term Evolution，简称为LTE)的系统中，定位可以达到20-30m左右的精度，基本可以满足一般的需求。由于垂直行业的融合，对于目前的定位提出了更高的要求，期望能够达到更快速的定位，更高精度的定位方式，这对下一代定位技术带来了不小的挑战。
定位技术在无线网络中的主要挑战是由用户的移动性和外部环境的变化带来的。定位技术的质量主要也是通过定位的准确性和定位计算的时间这两个指标来衡量。对于不同的场景(室外，室内，静止，移动)，不同的应用下，对于这些指标也有着不同的需求。全球卫星定位系统(Global Positioning System，简称为GPS)系统作为目前应用最广泛的技术，但是GPS主要在室外和郊外有很高的定位准确性，但是室内和城市的场景中，GPS的定位精度却不是非常理想。而在目前的无线通信系统中，有一半以上的移动设备是工作在室内的。为了增强定位的准确性和满足定位应用于各个场景的需求，在LTE中，使用了不同的基于基站的定位技术的方法，主要有观测到达时间(Time of Arrival，简称为TOA)、到达时间差(Observed Time Difference of Arrival，简称为OTDOA),上行到达时间差(Uplink Time Difference of Arrival，简称为UTDOA)，到达方向(Direction of Arrival，简称为DOA)或可称为到达角(Angle of Arrival，简称为AOA)，为了进一步提升定位的精度，这几种方法也可以混合使用。
首先，通过分析前面提到的各项技术在定位精度方面的指标，可以发现，其定位精度也只能达到几十米的定位精度，难以达到更高的精度要求，可随着网络业务的发展，用户定位的精度迫切需要提高。
再进一步，具体的，常用的定位场景，如基于距离信息和方向(角度)信息的定位，主要通过特定的定位参考信号(Positioning Reference Signal，简称为PRS)测量到达时间(Time of Arrival，简称为TOA)、到达时间差(Time Difference of Arrival，简称为TDOA)、DOA来实现定位。具体的，TOA和TDOA表示的是目标用户到不同基站的距离，在已知这三个基站的位置坐标情况下，通过三点定位法来定位目标用户。DOA表示的是目标用户到基站的角度，需要通过结合目标用户到基站的距离，实现用户的定位。又如基于指纹识别来进行定位，该方法需要将定位的整体区域细分为各个小区域，然后在每个区域内记录下多个传感器收到的用户特定的参考信号的接收信号强度(received signal  strength，简称为RSS)，生成一张表格。当要定位目标用户时，可以通过多个传感器接收到的RSS,与之前生成的表格进行比较，通过查表法，找到对应的区域。当然，区域划分地越小，定位的精度也会越高，但是建立表格的时间和计算的复杂度也会越高。以上两种常用的定位场景中，都必须多个基站/传感器参与定位，并且必须要传输额外的参考信号。
可见，现有的定位技术所采用的定位测量数据，主要存在使定位精度满足不了未来网络的需求的技术问题。更进一步地，现有的定位技术，还存在定位必须多节点参与，定位过程中必须有额外特定用于定位的定位参考信号传输，带来定位处理局限性大的技术问题。

具体实施方式
为使本申请解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面将以实施例的形式结合附图对本申请的技术方案作进一步详细的描述。所述详细的描述通过使用方框图、流程图和/或示例提出了设备和/或过程的各种实施例。由于这些方框图、流程图和/或示例包含一个或多个功能和/或操作，所以本领域技术人员将理解可以通过许多硬件、软件、固件或它们的任意组合单独和/或共同实施这些方框图、流程图或示例内的每个功能和/或操作。
本申请中“多个”是指两个或两个以上。本申请中的术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。本申请中的术语“第一”、“第二”等是为了区分不同的对象，并不限定该不同对象的顺序。
本申请中，名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。本申请所提及的所有“终端”/“终端设备”，在一些情况下可以是指移动设备，例如移动电话、个人数字助理、手持或膝上型计算机以及具有电信能力的类似设备，有些情况下还可以是穿戴设备或车载设备等，并包括未来5G网络中的终端或者未来演进的PLMN网络中的终端等。这种终端可以包括设备及其相关联的可移除存储模块(例如但不限于:包括订户标识模块(Subscriber Identification Module，简称为SIM)应用、通用订户标识模块(Universal Subscriber Identification Module，简称为USIM)应用或可移除用户标识模块(Removable User Identity Module，简称为R-UIM)应用的通用集成电路卡(Universal Integrated Circuit Card，简称为UICC)))。备选地，这种终端可以包括没有这种模块的设备本身。在其它情况下，术语“终端”/“终端设备”可以是指具有类似能力但是不可携带的设备，例如，台式计算机、机顶盒或网络设备。术语“终端”/“终端设备”还可以是指可端接用户的通信会话的任何硬件或软件组件。此外，“用 户终端”、“User Equipment”、“UE”、“站点”、“station”、“STA”、“用户设备”、“用户代理”、“User Agent”、“UA”、“用户装备”、“移动设备”和“设备”等皆是与本文中“终端”/“终端设备”同义的替代术语。为方便描述，本申请中，上面提到的设备统称为用户设备或UE。
本申请中提及的“接入节点”，是一种网络设备，部署在无线接入网中用以为终端设备提供无线通信功能的装置，能够负责调度和配置给UE的下行参考信号等功能。所述接入节点可以包括各种形式的宏基站、微基站、中继站、接入点等等，包括作为对传统无线电信系统中的对等设备改进的系统和设备。这种高级或下一代设备可以包含在长期演进LTE通信系统、5G通信系统、未来演进系统或者多种通信融合系统中，例如，LTE系统中包括的演进通用陆地无线接入网节点B(E-UTRAN Node B，简称为eNB)、5G包括的新无线接入网节点B(New Radio Access NodeB，简称为NR NodeB)、其他无线接入点或类似组件，在采用不同的无线接入技术的系统中，具备接入节点功能的设备名称可能会有所不同。为方便描述，本申请中，上述为UE提供无线通信功能的装置统称为接入节点。
本申请中，术语“测量功能实体”是指接入侧为UE定位提供上行定位测量的功能实体，其可以是设置在接入节点上的测量功能实体，也可以是独立于接入节点设置的测量功能实体，其中一种实现方式比如在以用户为中心、网络跟着用户移动而追踪的网络中，测量功能实体可以是网络中的传输接收点(transmission and reception point，简称为TRP)上的测量功能实体。只要实现相关功能的实体，皆属于“测量功能实体”的范畴。在不同系统中、不同的设置位置上，具备该功能实体功能的实体名称可能会有所不同，如“测量单元”、“定位测量单元(Location Measurement Unit，简称为LMU)”、“测量装置”、“定位测量装置”、“定位测量功能实体”等。为方便描述，本申请中，上述接入侧为UE定位提供上行定位测量的功能实体统称为测量功能实体。
本申请中，术语“定位服务功能实体”是指为UE提供定位服务的功能实体，其可以是独立于接入节点设置的服务功能实体或高层服务功能实体，也可以是设置于接入节点上的服务功能实体，只要实现相关功能的实体，皆属于“定位服务功能实体”的范畴。在不同系统中、不同的设置位置上，具备定位服务功能实体功能的实体名称可能会有所不同，例如“定位业务服务中心”、“增强服务移动定位中心(Enhanced Serving Mobile Location Centre，简称为E-SMLC)”等。为方便描述，本申请中，上述为UE提供定位服务的实体统称为定位服务功能实体。
图1给出了本申请涉及的一种网络系统架构，该系统用于UE的定位，其包括UE100、至少一个接入节点200和定位服务功能实体300，图1中以两个接入节点200为示例，本申请的定位系统中，可以涉及多个接入节点200，也可以只涉及一个接入节点200。可选的，如果该网络是以用户为中心、网络跟着用户移动而追踪的网络，那么系统还包括至少一个传输接收点400(transmission and reception point，简称为TRP)，这些传输接收点400具备其所在区域对应接入节点200的一些功能，能够监听未接入的非激活态用户发送的上行跟踪参考信号，以用户为中心，跟随用户的移动，进行监听。图1所示的系统中，为方便功能描述的划分，定位服务功能实体300与接入节点200给出了分离设置的示意，但这并非对其关系的限制，接入节点200上可以配置定位服务功能，定位服务功能实体300也可以设置于接入节点200上。
该系统对于UE100的定位，可以由UE100请求来触发，也可以由网络侧触发，如公安系统需要跟踪定位某些用户等。该系统中，可以从接入侧发送的下行参考考信号中获得包括信道估计和/或信道冲激响应的数据作为定位的测量数据，接入侧也可以从UE100发送的上行参考信号中获得包括信道估计和/或信道冲激响应的数据作为定位的测量数据，具体的，针对不同网络环境，接入侧可以是接入节点200或者TRP400来接收所述上行参考信号获得所述测量数据，在TRP400来接收的环境中，UE100可以是处于非激活态未接入、未与TRP400对应的接入节点200建立连接的UE，TRP400根据监听到的UE100发送的上行跟踪参考信号获得所述测量数据。
UE100和/或接入侧的测量功能实体，均能向定位服务功能实体300报告其所获得的用于UE100定位的所述测量数据(UE100与定位服务功能实体300之间是通过接入节点200进行通信连接)。定位服务功能实体300预先已经建立了包括信道估计和/或信道冲激响应的测量数据与终端设备位置的对应关系模型，在收到所述UE100和/或接入侧的测量功能实体报告的所述测量数据后，定位服务功能实体300可根据对应关系模型，根据所述测量数据对UE的位置进行估计，实现对UE的定位。如果定位服务功能实体300获得的所述测量数据包括多组，那么位置估计的计算结果会更精确，其中，多组测量数据可以有两种：一是这些测量数据是由UE与多个测量功能实体之间的上行参考信号/下行参考信号获得，二是这些测量数据是由UE与至少一个测量功能实体之间的上行参考信号和下行参考信号获得。
需要说明的是，图1所示的仅是本申请所涉及的一种网络系统架构的示例，本申请并不局限于此。类似的，本申请还可以在IEEE802.11的系统中应用，通过用作为定位测量功能实体的接入点(Access Point，简称为AP)或AP对应的测量点与站点(Station，简称为STA)之间的上行和/或下行参考信号获得的包括信道估计和/或信道冲激响应的测量数据进行STA定位，提高室内无线保真(Wireless Fidelity，简称为WiFi)的定位精度。

可以理解，UE向定位服务功能实体发送测量数据之前，已经获得所述测量数据，在本申请中，所述测量数据包括信道估计和/或信道冲激响应，是根据UE接收到的下行参考信号获得。其中，可选的，信道估计还可包括估计出的相应信道系数，如到达角AOA、多径数、时延扩展等信道特征参数，信道估计表示信号传输所经过的信道状况，针对信号在传输中会因为延迟和多径等因素造成相位和幅度畸变，对于信号接收端来说，要准确得到信号所携带的信息，就必须对已经发生畸变的信号进行均衡矫正，信号均衡矫正的前提是获得信号传输所经过的信道状况，即传输信道的信道估计，通过信道估计，接收机可以得到信道的冲激响应，从而为后续的相干解调提供所需的小区状态信息(Cell  State Information，简称为CSI)。信道冲激响应描述了信道将对信号产生的影响，信号通过信道从发射器被传输到接收器，信道会影响信号，使得从发射器发射的信号与在接收器接收的信号是不一样的，信道冲激响应描述了这样的影响，例如作为时间的函数，具体地，如果瞬时脉冲(或“冲激”)从发射器被发射，则信道冲激响应将是在接收器被接收到的信号，如果接收器可以确定信道冲激响应，那么接收器通常将能够更准确地解码接收信号中的符号，因为接收器可以考虑信道对接收信号的影响。对于信道估计，其算法从输入数据的类型来分，可以划分为时域和频域两大类方法。频域方法主要针对多载波系统；时域方法适用于所有单载波和多载波系统，其借助于参考信号或发送数据的统计特性，估计衰落信道中各多径分量的衰落系数。从信道估计算法先验信息的角度，则可分为以下三类：(1)基于参考信号的估计。该类算法按一定估计准则确定待估参数，或者按某些准则进行逐步跟踪和调整待估参数的估计值。其特点是需要借助参考信号，即导频或训练序列。基于训练序列和导频序列的估计统称为基于参考信号的估计算法。基于训练序列的信道估计算法适用于突发传输方式的系统。通过发送已知的训练序列，在接收端进行初始的信道估计，当发送有用的信息数据时，利用初始的信道估计结果进行一个判决更新，完成实时的信道估计。基于导频符号的信道估计适用于连续传输的系统。通过在发送的有用数据中插入已知的导频符号，可以得到导频位置的信道估计结果；接着利用导频位置的信道估计结果，通过内插得到有用数据位置的信道估计结果，完成信道估计。(2)盲估计。利用调制信号本身固有的、与具体承载信息比特无关的一些特征，或是采用判决反馈的方法来进行信道估计的方法。(3)半盲估计。结合盲估计与基于训练序列估计这两种方法优点的信道估计方法。一般来讲，通过设计训练序列或在数据中周期性地插入导频符号来进行估计的方法比较常用。而盲估计和半盲信道估计算法无需或者需要较短的训练序列，频谱效率高，因此获得了广泛的研究。但是一般盲估计和半盲估计方法的计算复杂度较高，且可能出现相位模糊(基于子空间的方法)、误差传播(如判决反馈类方法)、收敛慢或陷入局部极小等问题，需要较长的观察数据，这在一定程度上限制了它们的实用性。可选的，本申请采用基于参考信号的信道估计。
可选的，不同网络系统中，UE可以接收不同网络设备发送的下行参考信号，比如未设置分布式的与接入节点对应的传输接收点的网络中，UE可以接收接入节点发来的下行参考信号，在设置了分布式的与接入节点对应的传输接收点TRP的网络中(其中一种可以是以用户为中心、网络跟着用户移动而追踪的网络)，UE可以接收传输接收点TRP发来的下行参考信号；接入节点和传输接收点TRP上可设置有上行定位测量单元；可选的，本申请中，获得测量数据的下行参考信号可以有多种设计，可以是非特定额外用于定位的下行参考信号，如用于下行信道质量测量、下行信道估计、相位跟踪、同步等下行参考信号，比如小区参考信号(Cell Reference Signal，简称为CRS)；也可以是专用额外的定位参考信号，如定位参考信号(Positioning Reference Signal，简称为PRS)。此外，本申请中，可选的，所述下行参考信号可以是对应单接入节点的，也可以是对应多接入节点的，本申请的定位系统不是必须使用多接入节点，其可灵活选择。
UE通过接收的下行参考信号进行定位测量，可以计算获得各载波上的信道估计，
对于信道冲激响应的计算，现有技术中也有相关实现手段，可以采用各种能实现的方式，在此不做限定，本申请通过以下例子给出一个冲激响应计算的示例性说明，此示例不应理解为对本申请的限制：
通过各载波上的信道估计，进而可以计算出相应的信道冲激响应，对于信道冲激响应的计算，以下给出一种示例进行说明。假设用户在某一个位置某一时间获得的信道估计是h＝[h 1,...,h m,...h M],其中h m表示在第m个子载波上的信道估计，而子载波的总数有M个。对信道估计进行离散傅里叶反变换(Inverse Discrete Fourier Transform，简称为IDFT)或者快速傅里叶反变换(Inverse Fast Fourier Transform，简称为IFFT)，假设傅里叶变换的系数为L,并且L≥M。那么对于信道估计进行L点的IDFT或者IFFT，得到同样长度为L的序列，即为信道冲激响应。可选地，也可以为了减少发送量，可以对长度为L的信道冲激响应进行滤波，抽取出有效的信息进行传递。具体的过程可以如下：
1)从参考信号得到的信道估计是h＝[h 1,...,h m,...h M]
2)对信道估计两边对称的补零，得到长度为L的信道估计序列h'＝[0,...,0,h 1,...,h m,...h M,0,...,0]＝[h' 1,...,h' l,...,h' L]
3)对补零后的序列h'进行IDFT，或者IFFT运算，得到同样长度为L的信道冲激响应序列f'＝[f' 1,...,f l',...f L']。
4)如果需要进行带通滤波的话，找到f'中绝对值最大的那个点，然后将包含此点的连续K个点选出，得到序列f＝[f 1,...,f k,...f K]，即为经过滤波以后的信道冲激响应。
通过以上的方法，得到了信道估计和信道冲激响应后，每组信道估计对应一个信道冲激响应。
可选的，UE可以周期性地向定位服务功能实体报告所述测量数据，如果UE只支持基于信道估计和/或信道冲激响应的定位测量，则默认报告包括信道估计和/或信道冲激响应的测量数据，如果UE支持包括基于信道估计和/或信道冲激响应的多种定位测量方式，可以默认根据预设优先级条件确定定位测量方式对应的测量数据，或者报告所有测量方式对应的测量数据，本申请中涉及报告包括信道估计和/或信道冲激响应的测量数据。当然UE也可以根据网络侧的指示报告对应的包括信道估计和/或信道冲激响应的测量数据，或者UE根据定位服务功能实体的定位请求启动定位测量。
S102.定位服务功能实体基于收到的测量数据，对UE的位置进行估计，实现UE定位。
对于定位服务功能实体，会先建立所述测量数据和UE位置的对应关系模型，此模型可以预先一次性训练或周期性进行训练。其中，通过在训练阶段，将在不同位置得到的信道估计和/或信道冲激响应，利用机器学习的算法，提取特征信息，建立信道估计、信道冲激响应和用户位置的关系。可选的，可以通过神经网络的训练方法建立该关系模型，通过神经网络学习大量的输入数据和输出数据，对输入输出的数据进行分类和归纳，利用机器学习的算法找到输入与输出之间的联系。一旦有新的输入，就可以通过已经训练好的神经网络得到输出的结果。对于神经网络，输出量可以看出一个关于输入和权重系数的一个函数，多次训练的主要的目的就是找到合适的权重系数，使得得到的输出量和已知的输出量之间的差最小，那么这个权重系数就是对应的已经训练好的神经网络模型， 而这个不断调整权重系数的过程也是一个迭代的过程，神经网络技术为现有技术在此不展开描述。这个训练阶段就是机器学习的过程，而训练好的神经网络，就可以用于由新的输入数据，得到输出的数据。
在本申请中，通过预先建立好的所述测量数据和UE位置的对应关系模型，假设该模型是结构如图3所示的神经网络模型，图3给出了一种可用于本申请建立测量数据与终端设备位置对应关系模型的神经网络示例图，该神经网络分为三层，输入层31、隐藏层32和输出层33，每一层上均有一定数量的神经元，为节点，其中该模型中，示例给出输入层31有4个神经元，隐藏层32有6个神经元，输出层33有3个神经元。在训练过程中，如果基于信道估计进行定位，则根据信道估计对应的4个输入，和UE坐标对应的3个输出(即，对应三维坐标)，参照已知的UE坐标对应的3个输出进行训练；利用训练好的该模型，在定位过程中，针对模型训练采用的接入节点/传输接收点，获得定位测量时其和UE间的下行信道估计对应的4个输入，将其输入到该训练好的模型中，最终获得UE位置对应的3个输出，即UE的三维坐标，实现UE的定位。该模型仅是示例，本申请的可用的模型，输入层不限于4个输入神经元，同时隐藏层可以有多层不止一层，也不限于6个神经元，此外输出层神经元可以根据要获取的UE位置信息的不同而调整输出的神经元个数，根据对UE定位的需要，如果要获得UE的三维坐标进行三维定位就可选择3个输出神经元，如果是二维定位就可选择2个输出神经元。
以上仅为示例，本申请中定位测量输入的测量数据有三种类型可选：第一种是信道估计、第二种信道冲激响应、第三种是信道估计加信道冲激响应。以上示例为4个输入的示例，该输入神经元的个数不限于4，训练时可以根据情况选定不同的输入个数。假设N个基站和一个UE通信，如果每个基站对应有M个子载波，则对于每个位置可以得到NM个信道估计，如果输入的是信道估计，由于信道估计是复数，分为实部和虚部两部分，那么输入的神经元就有2NM个，而输出的神经元是3个，表示目标用户的三维坐标。如果输入的是信道冲激响应，假设经过滤波以后有K个取样，同样信道冲激响应也是复数，那么输入的神经元也就是2NK个，同样，输出的神经元也是3个，表示目标用户的三维坐标。如果输入的是信道估计加信道冲激响应，那么输入的神经元就是2NM+2NK个，同样，输出的神经元也是3个，表示目标用户的三维坐标。
以上通过神经网络建立输入与输出关系模型的方式仅为示例，不作为对本申请的限制，本申请还可以采用其他输入与输出对应关系模型建立的方式，比如能通过反馈进行学习训练的算法方式都可用于本申请中。
通过基于信道估计、信道冲激响应进行定位的方式，经验证，在外场测试的环境下，仿真的结果如表1所示：
Parameters 定位精度平均值
信道估计 11m
信道冲激响应 8m
2WLS(LTE标准) 30m
表1
可见，LTE现有的如基于AOA、TOA的加权最小二乘(Weighted Least Squares，简 称为WLS)定位精度在大概30m左右，使用信道估计进行定位可以到达大概11m的定位精度，使用信道冲激响应的定位精度可以达到8m左右，本申请的测量数据用于定位，相比现有技术有一倍多的增益。
本申请实施例的一种终端设备的定位方法，通过UE把包括信道估计和/或信道冲激响应的测量数据报告定位服务功能实体的交互流程，实现了对UE高精度、低局限性的定位。
实施例二
图4为本申请提供的一种用于终端设备定位的方法的第二个实施例的流程图。本实施例与实施例一的区别在于，该实施例中，增加了UE与定位服务功能实体之间交互测量要求指示信息的流程，UE获得何种测量数据是根据定位服务功能实体的指示，与实施例一相同或类似的内容在本实施例中不再赘述。
该方法包括：
S201.定位服务功能实体向UE发送指示UE需获取的测量数据的测量要求指示信息，UE接收该指示信息；
UE获得哪些测量数据，可以由定位服务功能实体根据其选定的定位处理方式来指示UE获得对应的测量数据进行有效定位。在UE支持多种定位方式的场景中，定位服务功能实体还可指示UE获取需要使用的一种或多种定位方式对应的测量数据。可选的，该指示信息可以携带在已知的消息中或在新的消息中，可通过其中对应的比特位指示，比如，对应测量数据A的比特位取值1时表示需要UE获取并上报测量数据A，取值0则表示不需要获取该测量数据A，或者取值0需要获取该测量数据A，取值1时表示不需要获取，此为示例不对本申请构成限制。
可选的，定位服务功能实体还向UE发送辅助信息，用于辅助UE的定位测量，辅助信息可以包括小区编号、下行参考信号的配置信息等，这样能够辅助UE知道下行参考信号是哪个或哪些基站发的，下行参考信号在哪里接收，如下行参考信号的配置信息等，即便使用多接入节点进行UE定位，UE能快速确定下行参考信号的接收配置。如果UE已接入某接入节点，并且基于该单接入节点进行定位测量，且已知下行参考信号的配置信息，则也可以无需定位服务功能实体发送辅助信息。
可选的，辅助信息与所述指示信息可以携带在同一消息中发送，或携带在不同消息中发送。
S202.UE接收接入节点/传输接收点发来的下行参考信号；
UE在接收到定位服务功能实体发来的测量要求指示后，进行相应的测量，UE通过接收下行参考信号获得对应所述测量要求指示的测量数据，如果定位服务功能实体有发送所述辅助信息，则UE根据所述辅助信息接收下行参考信号。UE接收下行参考信号，可以从接入节点接收下行参考信号，如果网络中设置有与接入节点分布设置的接入节点对应的传输接收点，UE也可以从相应传输接收点接收下行参考信号。对于发送下行参考信号的接入节点/传输接收点，其上可以设置有用于上行定位测量的接入侧的测量功能实体，也可以未设置有该测量功能实体。
S203.UE基于所述指示信息根据接收到的下行参考信号，获得所述测量数据；
UE基于定位服务功能实体发来的测量要求指示，根据接收的下行参考信号获得对应所述测量要求指示的测量数据，如果需要测量信道估计和/或信道冲激响应，则UE进行 相应测量，获得信道估计和/或信道冲激响应。
S204.UE向定位服务功能实体发送获得的测量数据，定位服务功能实体接收测量数据。
UE根据定位服务功能实体的指示，进行相应的测量，获得对应的测量数据，反馈给定位服务功能实体。
S205.定位服务功能实体根据接收到的所述测量数据，估计UE的位置，实现对UE定位。
定位服务功能实体可以根据预先建立的已经训练好的模型，将收到的包括信道估计和/或信道冲激响应的测量数据作为输入，计算得到UE的位置坐标。
本实施例中，可在UE支持多种测量方式的场景下，通过定位服务功能实体向UE发送测量要求指示信息的交互流程，使得UE能有针对性的进行定位测量并报告测量数据给定位服务功能实体，从而实现定位服务功能实体对UE位置的有效估计，也减少了UE无效定位测量和数据传输的开
对于以上进行终端设备定位的实施例，如果在系统中，UE均支持基于信道估计和/或信道冲激响应的定位测量，系统默认UE均支持这种定位方式，那么定位服务功能实体可以选择默认所有UE具有支持基于信道估计和/或信道冲激响应的定位测量的能力。如果在系统中，并非默认所有UE具有支持基于信道估计和/或信道冲激响应的定位测量的能力，那么定位服务功能实体需确定UE所支持的定位测量的能力，以确定是否采用基于信道估计和/或信道冲激响应的定位测量方式对UE进行定位。定位服务功能实体确定UE所支持的定位测量的能力，可以通过UE报告来获知UE所支持的能力，确定UE是否支持基于信道估计和/或信道冲激响应的定位测量，下面通过具体交互流程进行描述。
图5为本申请中确定终端设备支持的定位测量能力的交互流程示意图。如图5所示，确定UE所支持的定位测量能力，包括以下步骤：
S301.定位服务功能实体向UE发送UE的能力请求。
该步骤为可选步骤，可以理解的，定位服务功能实体确定UE所支持的定位测量能力，可以在需要时通过发送能力请求发起，指示UE反馈，也可以由UE发起，比如入网时上报、发生变化时动态上报、也可以周期性地上报。通过定位服务功能实体发送能力请求，可以按需触发UE反馈，减少了UE频繁报告带来的开销。
如果该能力请求是发给UE，可选的，可以携带在已有消息中发送，也可以携带在新消息中发送。
需要说明的是，以下步骤S302和S303并非流程中的先后步骤，其二者是UE具备定位测量能力在不同情况下的两种处理方式。
S302.UE向定位服务功能实体反馈UE所支持的能力，其中指示UE支持基于信道估计和/或信道冲激响应的测量。
UE可以通过在向定位服务功能实体反馈的消息中特定的字段或者某些比特位等方式来指示UE是否支持某些能力，可选的，如系统存在多种定位测量方式，则在这些定位方式对应的指示位，通过0、1等取值信息来指示UE是否支持这种能力。
可选的，对于UE而言，如果具备检测信道估计和/或信道冲激响应的能力，则在接收到上述请求后，在消息中相关的能力信息中增加1比特信息，如该比特位取值1，表示 UE能够检测信道估计和/或信道冲激响应。此举例，并非对本申请的限制，也可通过该比特位取值0来指示UE支持该能力。
S303.UE向定位服务功能实体反馈UE所支持的能力，其中指示UE不支持基于信道估计和/或信道冲激响应的测量。
UE可以通过在向定位服务功能实体反馈的消息中特定的字段或者某些比特位等方式来指示UE是否支持某些能力，可选的，如系统存在多种定位测量方式，则在这些定位方式对应的指示位，通过0、1等取值信息来指示UE是否支持这种能力。
可选的，对于UE而言，如果不具备检测信道估计和/或信道冲激响应的能力，则在接收到上述请求后，在消息中相关的能力信息中增加1比特信息，如该比特位取值0，表示UE不能够检测信道估计和/或信道冲激响应。此举例，并非对本申请的限制，也可通过该比特位取值1来指示UE不支持该能力。
S304.定位服务功能实体根据接收到的UE能力反馈信息，确定UE的能力。
定位服务功能实体能够根据UE能力反馈信息，确定UE是否支持基于信道估计和/或信道冲激响应的定位测量，进而确定是否采用该方式实现UE的位置估计。在确认UE支持该方式时，可分别结合上述实施例一和实施例二的方式实现UE的位置估计：结合实施例一，定位服务功能实体可在S101步骤UE报告测量数据之前通过UE报告的能力信息确定UE的定位测量能力，也可通过UE将定位测量能力和相关的测量数据一起上报时确定UE的定位测量能力并同时对UE进行定位；结合实施例二，定位服务功能实体可在S201步骤发送测量要求指示信息之前确定UE的定位测量能力，根据UE的定位测量能力向UE发送测量要求指示信息。
需要说明的，UE能力的确定，不限于以上由UE报告来确定，可选的，如果UE能力为静态固定的，还可以通过管理方(如，设备能力寄存功能实体)获得UE所支持的能力，定位服务功能实体可以选择跟管理方进行交互，确定UE所支持的定位能力。
该设计能够使得定位服务功能实体确定UE所能支持的定位测量方式，从而有效实现定位。
实施例三

通过接收的UE发来的上行参考信号，可以计算获得各载波上的信道估计，并进而可以计算出相应的信道冲激响应。对于信道估计和信道冲激响应的相关描述和获取方式，参见实施例一，在此不再赘述。
可选的，所述测量功能实体可以周期性地向定位服务功能实体报告所述测量数据，如果所述测量功能实体只支持基于信道估计和/或信道冲激响应的定位测量，则默认报告包括信道估计和/或信道冲激响应的测量数据，如果所述测量功能实体支持包括基于信道估计和/或信道冲激响应的多种定位测量方式，可以默认根据预设优先级条件确定的定位测量方式对应的测量数据，或者报告所有测量方式对应的测量数据，本申请中涉及报告包括信道估计和/或信道冲激响应的测量数据。当然所述测量功能实体也可以根据网络侧的指示报告对应的包括信道估计和/或信道冲激响应的测量数据。
S402.定位服务功能实体基于收到的测量数据，对UE的位置进行估计，实现UE定位。
对于定位服务功能实体，会先建立所述测量数据和UE位置的对应关系模型，相关建立方式举例说明参见实施例一的描述，在此不再赘述。定位服务功能实体根据所述测量功能实体报告的根据UE发来的上行参考信号进行定位测量获得的所述测量数据，通过预先建立的测量数据与UE位置对应关系模型，根据所述测量数据，得到UE位置的相关输出，实现了UE定位。

S502.定位服务功能实体向接入侧的测量功能实体发送指示接入侧的测量功能实体 需获取的测量数据的测量要求指示信息，接入侧的测量功能实体接收该指示信息；
接入侧的测量功能实体获得哪些测量数据，可以由定位服务功能实体根据其选定的定位处理方式来指示接入侧的测量功能实体获得对应的测量数据进行UE的有效定位。在接入侧的测量功能实体支持多种定位方式的场景中，定位服务功能实体还可指示接入侧的测量功能实体获取需要使用的一种或多种定位方式对应的测量数据。可选的，该指示信息可以携带在已知的消息中或在新的消息中，可通过其中对应的比特位指示，比如，对应测量数据A的比特位取值1时表示需要接入侧的测量功能实体获取并上报测量数据A，取值0则表示不需要获取该测量数据A，或者取值0需要获取该测量数据A，取值1时表示不需要获取，此为示例不对本申请构成限制。
可选的，定位服务功能实体还向接入侧的测量功能实体发送辅助信息，用于辅助接入侧的测量功能实体的定位测量，辅助信息可以包括UE所在的小区编号、上行参考信号的配置信息等，这样能够辅助接入侧的测量功能实体知道上行参考信号是哪个UE发的，上行参考信号在哪里接收，如上行参考信号的配置信息等。如果该待定位的UE已接入某测量功能实体对应的接入节点，并且基于该单接入节点进行定位测量，且已知要对该UE进行定位及上行参考信号的配置信息，则也可以无需定位服务功能实体发送辅助信息。

本实施例中，可在接入侧的测量功能实体支持多种测量方式的场景下，通过定位服务功能实体向接入侧的测量功能实体发送测量要求指示信息的交互流程，使得接入侧的测量功能实体能有针对性的进行定位测量并报告测量数据给定位服务功能实体，从而实现定位服务功能实体对UE位置的有效估计，也减少了接入侧的测量功能实体无效定位测量和数据传输的开销。
对于以上由接入侧进行终端设备定位的实施例，如果在系统中，接入侧的测量功能实体均支持基于信道估计和/或信道冲激响应的定位测量，系统默认接入侧均支持这种定位方式，那么定位服务功能实体可以选择默认所有接入侧的测量功能实体具有支持基于信道估计和/或信道冲激响应的定位测量的能力。如果在系统中，并非默认所有接入侧的测量功能实体具有支持基于信道估计和/或信道冲激响应的定位测量的能力，那么定位服务功能实体需确定接入侧的测量功能实体所支持的定位测量的能力，以确定是否采用基于信道估计和/或信道冲激响应的定位测量方式对UE进行定位。下面通过具体交互流程进行描述。
接入侧的测量功能实体可以设置于接入节点上，或者设置于与对应接入节点分布设置的装置上，其中一种实现方式可以是设置在接入节点对应的传输接收点TRP上。定位服务功能实体确定接入侧的测量功能实体所支持的定位能力，针对所述测量功能实体的不同设置方式场景，即不论是否设置在接入节点上，定位服务功能实体均可通过测量功能实体对应的接入节点(即，作为接入侧的测量功能实体的接入节点或管理接入侧的测量功能实体的接入节点)确定测量功能实体所支持的定位能力，以下以定位服务功能实体与接入节点交互确定测量功能实体的定位测量能力为例进行描述。图8为本申请中确定接入侧的测量功能实体所支持的定位测量能力的交互流程示意图。如图8所示，确定接入侧的测量功能实体所支持的定位测量能力，包括以下步骤：
S601.定位服务功能实体向接入侧的测量功能实体对应的接入节点发送定位能力请求。
该步骤为可选步骤，可以理解的，定位服务功能实体确定接入侧的测量功能实体所支持的定位测量能力，可以在需要时通过发送定位能力请求发起，指示对应接入节点反馈，也可以由对应接入节点发起，如入网时上报、有变化时动态上报以及也可以周期性地报告。通过定位服务功能实体发送能力请求，可以按需触发定位能力反馈，减少了接入节点频繁报告带来的开销。
如果该能力请求是发给接入节点，可选的，可以携带在已有消息中发送，也可以携带在新消息中发送。
需要说明的是，以下步骤S602和S603并非流程中的先后步骤，其二者是接入侧的测量功能实体具备定位测量能力在不同情况下的两种处理方式。
S602.接入侧的测量功能实体对应的接入节点向定位服务功能实体反馈其或对应测量功能实体所支持的能力，其中指示支持基于信道估计和/或信道冲激响应的测量。
所述接入节点可以通过在向定位服务功能实体反馈的消息中特定的字段或者某些比特位等方式来指示其或对应测量功能实体是否支持某些能力，可选的，如系统存在多种定位测量方式，则在这些定位方式对应的指示位，通过0、1等取值信息来指示是否支持这种能力。
可选的，对于接入节点而言，如果其或对应测量功能实体具备检测信道估计和/或信道冲激响应的能力，则在接收到上述请求后，在消息中相关的能力信息中增加1比特信息，如该比特位取值1，表示能够检测信道估计和/或信道冲激响应。此举例，并非对本申请的限制，也可通过该比特位取值0来指示支持该能力。
S603.接入侧的测量功能实体对应的接入节点向定位服务功能实体反馈其或对应测量功能实体所支持的能力，其中指示不支持基于信道估计和/或信道冲激响应的测量。
所述接入节点可以通过在向定位服务功能实体反馈的消息中特定的字段或者某些比特位等方式来指示其或对应测量功能实体是否支持某些能力，可选的，如系统存在多种定位测量方式，则在这些定位方式对应的指示位，通过0、1等取值信息来指示是否支持这种能力。
可选的，对于接入节点而言，如果其或对应测量功能实体不具备检测信道估计和/或信道冲激响应的能力，则在接收到上述请求后，在消息中相关的能力信息中增加1比特信息，如该比特位取值0，表示不能够检测信道估计和/或信道冲激响应。此举例，并非对本申请的限制，也可通过该比特位取值1来指示不支持该能力。
S604.定位服务功能实体根据接收到的能力反馈信息，确定接入侧的测量功能实体的定位能力。
定位服务功能实体能够根据接入节点的反馈信息，确定接入节点或其对应的测量功能推是否支持基于信道估计和/或信道冲激响应的定位测量，进而确定是否采用该方式实现UE的位置估计。在确认支持该方式时，可分别结合上述实施例三和实施例四的方式实现UE的位置估计：结合实施例三，定位服务功能实体确定的定位测量能力，可在S401步骤接入侧的测量功能实体报告测量数据之前通过接入侧的测量功能实体或其对应的管理实体报告的能力信息来确定，也可以通过接入侧的测量功能实体或其对应的管理实体将定位测量能力和相关的测量数据一起报告来确定；结合实施例四，定位服务功能实体可在S501步骤选定测量功能实体之前确定测量功能实体的定位测量能力，根据测量功能实体的定位测量能力选定测量功能实体；如果不必有S501的步骤，那么定位服务功能实体可在S502向测量功能实体发送测量要求指示信息之前确定测量功能实体的定位测量能力。
需要说明的，接入侧的测量功能实体能力的确定，不限于以上由作为接入侧的测量功能实体的接入节点或管理接入侧的测量功能实体的接入节点报告来确定，可选的，还可以通过其他管理方(如，操作管理维护(Operation Administration and Maintenance，简称为OAM)等管理实体)获得接入侧的测量功能实体所支持的能力，定位服务功能实体可以选择跟其他管理方进行交互，确定测量功能实体所支持的定位能力。
该设计能够使得定位服务功能实体确定接入侧的测量功能实体所能支持的定位测量方式，从而有效实现定位。
以上实施例中UE位置估计是分别从UE侧发送基于信道估计和/或信道冲激响应的定位测量数据和接入侧发送基于信道估计和/或信道冲激响应的定位测量数据的角度进行介绍。可以理解的是，定位服务功能实体对UE的位置估计可以根据UE报告的测量数据，也可以根据接入侧报告的测量数据，还可以根据UE和接入侧都报告的测量数据进行UE位置估计。下面侧重从定位服务功能实体进行位置估计的角度进行介绍。
实施例五
图9为本申请中另一种用于终端设备定位的方法的实施例的流程图。该实施例以介绍定位服务功能实体进行位置估计的计算方法为主，仅描述与发送定位测量数据相关的主要步骤，其并非限定只涉及这些步骤，其还可以包括实施例二和/或实施例三中的其他相关步骤，具体可参考上述实施例，在此不再赘述。
该方法包括：
S701.接入侧的测量功能实体获得基于信道估计和/或信道冲激响应的定位测量数 据。
S702.接入侧的测量功能实体发送基于信道估计和/或信道冲激响应的定位测量数据给定位服务功能实体，定位服务功能实体接收该定位测量数据。
S701与上述实施例中S504类似，S702与上述实施例中S401、S505类似，可参考上述S401、S504和S505的描述，在此不再赘述。
S703.UE获得基于信道估计和/或信道冲激响应的定位测量数据。
S704.UE发送基于信道估计和/或信道冲激响应的定位测量数据给定位服务功能实体，定位服务功能实体接收该定位测量数据。
S703与上述实施例中S203类似，S704与上述实施例中S101和S204类似，可参考上述S101、S203和S204的描述，在此不再赘述。
需要说明的是，S701和S702与S703和S704并非存在必然的先后顺序，仅是针对不同执行动作的对象而言。其也不是必须都存在，在不同场景下，可以不存在S701和S702，或者不存在S703和S704。
S705.定位服务功能实体基于收到的定位测量信息，对UE的位置进行估计，实现定位。
定位服务功能实体，可以基于UE和/或接入侧的测量功能实体报告的测量数据进行UE的位置估计。针对基于UE或接入侧的测量功能实体报告的测量信息进行UE的位置估计，可分别参考上述实施例中S102、S205或S402、S506介绍的方式进行UE的位置估计；针对基于UE和接入侧的测量功能实体报告的测量信息进行UE的位置估计，可参考上述实施例中S102、S205和S402、S506介绍的方式进行UE的位置估计。可选的，可在建立测量数据与UE位置对应关系模型时，同时考虑UE侧获得的测量数据和接入侧获得的测量数据，定位时根据已经建好的对应关系模型，根据UE侧报告的测量数据和接入侧报告的测量数据获得UE的位置估计；可选的，也可以在建立测量数据与UE位置对应关系模型时，分别考虑UE侧获得的测量数据、接入侧获得的测量数据，即有分别针对UE侧和接入侧的对应关系模型，定位时将根据UE报告的测量数据所获得的位置估计结果，以及根据接入侧报告的测量数据所获得的位置估计结果取平均值，确定最终的UE位置。
本申请的定位系统进行定位可以是针对单接入节点/接入侧的测量功能实体的，也可以是针对多接入节点/接入侧的测量功能实体的。对于定位服务功能实体，基于信道估计和/或信道冲激响应的定位方法针对这两种场景，可结合之前给出的神经网络示例，分别进一步举例说明：
如果是单接入节点/接入侧的测量功能实体的情况，在训练阶段，用下行的信道估计或/和信道冲激响应作为输入量，将输出的坐标表示为与输入量和神经网络中每个节点的权重系数和偏移系数相关的函数，训练的目的就是通过迭代调整神经网络中每个节点的权重系数和偏移系数，使得训练后得到的输出的位置坐标和已知的位置坐标的均方差尽可能小，迭代的过程可以在预先设定的次数后或者均方差小于某个预设值后停止。之后在定位阶段，当定位中心接收到下行的信道估计或/和信道冲激响应后，基于已经训练好的神经网络，通过已经训练的权重系数和偏移系数，得到输出的位置坐标，即为该用户的位置坐标。
如果是多接入节点/接入侧的测量功能实体的情况，可以有两种方法。第一种，训练阶段和单接入节点/接入侧的测量功能实体情况一样，也用同样数量的输入，在定位阶段， 定位中心收到每个接入节点/接入侧的测量功能实体的一组下行的信道估计或/和信道冲激响应，所以每个接入节点/接入侧的测量功能实体都能通过神经网络得到一个用户的坐标，然后将得到的位置坐标平均后即可得该用户的位置坐标。第二种方法是，在训练阶段，如果有N个接入节点/接入侧的测量功能实体，那么将这N组信道估计或/和信道冲激响应，作为输入，输出还是一个用户的位置坐标，经过训练后得到训练后神经网络每个节点的权重系数和偏移系数。之后在定位阶段，在收到每个接入节点/接入侧的测量功能实体的下行信道估计或/和信道冲激响应后，将N组作为输入，得到用户的位置坐标。
本申请实施例的终端设备的定位方法，通过UE和/或接入侧的测量功能实体把包括信道估计和/或信道冲激响应的测量数据报告定位服务功能实体的交互流程，实现了对UE高精度、低局限性的定位。
上述主要从系统各实体之间交互进行终端设备定位的流程角度对本申请实施例提供的方案进行了介绍。可以理解的是，各实体，为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
