一种定位信息上报方法、设备及通信系统
相关申请的交叉引用
本申请要求在2021年04月23日提交中国专利局、申请号为202110442444.0、申请名称为“一种定位信息上报方法、设备及通信系统”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
本申请实施例涉及通信技术领域，尤其涉及一种定位信息上报方法、设备及通信系统。
背景技术
高精度定位是第五代(5th generation，5G)新无线(new radio，NR)移动通信网络的关键技术之一。通过蜂窝定位能够准确识别终端设备的位置，从而为用户提供基于定位的服务，例如导航、货物配送等。其中，蜂窝定位是通过测量多个5G基站(gNodeB，gNB)与终端设备间的直线距离，获取5G基站与终端设备的几何位置关系，之后根据已知的gNB位置解算出终端设备的位置。
终端设备定位依赖于终端设备与gNB间的视距(line of sight，LOS)(也即终端设备与gNB间的直线距离)的测量。然而在生产生活的实际应用中，由于遮挡物(例如树、建筑、墙壁等)的存在会反射定位信号，因此gNB测量的信号传播距离有可能为非视距(non-line of sight，NLOS)传播距离。在对终端设备定位时，由于NLOS径的存在，使得终端设备的定位精度较差。
发明内容
本申请提供一种定位信息上报方法、设备及通信系统，以使定位服务器可参考终端设备与接入网设备之间的信道情况，更加准确地对终端设备进行定位。
第一方面，本申请提供一种定位信息上报方法，该定位信息上报方法可通过终端设备来执行，该终端设备可以理解为定位标签、车载设备、手机等，本申请在此不作具体限定。本申请在执行定位信息上报方法时，终端设备可接收来自一个或多个接入网设备的定位参考信号；并发送定位测量信息至服务接入网设备；定位测量信息包括：终端设备基于定位参考信号确定的一个或多个定位测量结果和分别与一个或多个定位测量结果对应的LOS状态信息。
需要说明的是，服务接入网设备可以为终端设备提供通信服务，如：终端设备可通过服务接入网设备接收来自其他终端设备的消息，或者终端设备可通过服务接入网设备转发消息，本申请在此不限定服务接入网设备可以为终端设备提供哪些通信服务。本申请中，服务接入网设备也可以为接入网设备中的一个，服务接入网设备也可向终端设备发送定位参考信号；亦或者服务接入网设备与接入网设备是相互独立的，服务接入网设备并不向终端设备发送定位参考信号，在此仅接收来自终端设备的定位测量信息，无论服务接入网设备是上述的哪种情况均适用于本申请的方案。另外还要说明的是，接入网设备或服务接入 网设备可以为基站，也可以为传输接收点(transmission reception point，TRP)，本申请在此不具体限定。
此外，终端设备可通过最大似然估计方法或者多重信号分类算法(multiple signal classification algorithm，MUSIC)对终端设备与任一接入网设备间的信道进行估计，确定定位测量结果。当然，在实际应用中也可通过其他方式确定定位测量结果，本申请在此并不具体限定，在此仅仅通过上述的方法或算法作示例性说明。
还要说明的是，一个定位测量结果是终端设备根据一个接入网设备发送的定位参考信号确定的，且该定位测量结果对应一个LOS状态信息，该LOS状态信息可以指示定位测量结果是LOS的还是NLOS的。其中，定位测量结果可通过到达时间(time of arrival，TOA)，和/或，到达角度来指示，当然也可通过其他指标来指示，本申请在此不作具体限定。另外，终端设备可通过一致性分析算法(也即终端设备的不同的天线单元接收到定位参考信号后，参考信号的波动程度确定LOS状态信息)对终端设备与接入网设备间的信道进行估计确定LOS状态信息。此外本申请还可能根据其他方法确定LOS状态信息，在此不一一示意，凡是可以基于定位参考信号，确定定位测量结果和LOS状态信息的方法均适用于本申请。
本申请实施例中，终端设备在定位时反馈的LOS状态信息可以指示定位测量结果是LOS的还是NLOS的，在定位时，定位服务器根据定位测量结果对应的LOS状态信息可以获悉哪个定位测量结果是可靠的，便于更加精确地确定终端设备的位置。
在一种可选的实施方式中，定位测量结果为终端设备通过第一算法对终端设备与接入网设备间的定位参考信号解算确定的；LOS状态信息为终端设备通过第二算法对终端设备与接入网设备间的信道进行解算确定的。
需要说明的是，终端设备可通过第一算法确定终端设备与接入网设备间的定位测量结果。其中，第一算法可以为最大似然估计算法，还也可以为MUSIC算法等，本申请在此不具体限定。其中，最大似然估计算法也即通过将本地生成的定位参考信号与接收到的定位参考信号进行相关运算，大于阈值的所有峰值点对应的时间即为定位参考信号通过不同径的到达时间，第一个峰值点到达时间即为LOS径的TOA。MUSIC算法是一种基于矩阵特征空间分解的方法，将观测到的参考信号的自相关矩阵分解为信号子空间和噪声子空间，并构建空间谱，空间谱的谱峰对应的TOA值即为测量值。
终端设备可通过第二算法对终端设备与接入网设备间的信道进行LOS状态检测。其中，第二算法可以为一致性分析算法，还可以为基于人工智能(artificial intelligence，AI)的算法。其中，一致性分析算法是通过检测不同的天线单元下，终端设备的信号强度波动情况，来确定LOS状态，例如，若终端设备的信号强度波动小，则认为定位测量信息为LOS；若终端设备的信号强度波动大，则认为定位测量信息为NLOS。其中，基于AI的算法也即利用神经网络基于终端与各接入网间的历史信道数据进行神经网络模型的训练，在进行LOS判断时，直接输入估计得到的信道系数或者是接收到的参考信号输入神经网络模型，输出LOS检测结果。
在一种可选的实施方式中，LOS状态信息为多个，将多个定位测量结果按照对应的LOS概率进行排序，通过排序指示一个或多个定位测量结果对应的LOS状态信息通过排序进行指示。将多个定位测量结果按照对应的LOS概率进行排序，能够隐式的指示各个测量量之间的LOS概率大小的相对关系，能够节省额外的LOS状态信息比特(也即节省非隐士指示占用的信息比特数)，同时达到指示定位服务器各测量量的权重大小，提升定位 精度的目的。
此外，终端设备在接收到来自多个接入网设备的定位参考信号时，可基于多个定位参考信号确定多个定位测量结果，不同的定位测量结果对应的LOS概率是不同的，终端设备可以与服务接入网设备提前约定仅仅上报LOS概率排序靠前的几个定位测量结果。
在一种可选的实施方式中，其中，LOS状态信息包括：终端设备与各接入网设备间信道的LOS判决结果或LOS概率。
需要说明的是，LOS状态信息仅仅是示意性说明，LOS状态信息可指示终端设备与接入网设备之间信道是LOS还是NLOS，在实际应用中LOS状态信息还可称为LOS结果，LOS状态等，LOS状态信息也可以包含其它名称的LOS信道指示信息，本申请在此并不具体限定。本申请中除了可包括上述提及的LOS判决结果、LOS概率以外还可以包括LOS质量、LOS置信度等，LOS质量或者LOS置信度是基于参考信号对信道进行LOS检测后，确定的信道的一种度量指标，LOS质量或者LOS置信度越高代表LOS概率越大，信道越有可能为LOS的，LOS质量或者LOS置信度越低LOS概率越小，信道越有可能为NLOS信道。另外上述提及的LOS状态信息也不仅仅为终端设备与接入网设备之间信道的LOS情况，还可以是终端设备与接入网设备之间信道的NLOS情况，也即LOS状态信息可以为终端设备与接入网设备间信道的NLOS判决结果或NLOS概率等，本申请在此并不具体限定。
其中，LOS概率是通过LOS检测算法(例如一致性分析算法)对终端设备和接入网设备间的信道进行LOS检测计算得到的，上报LOS概率(可对LOS概率量化后上报)能够指示信道LOS状态信息，有利于提升定位精度。LOS判决结果是通过将LOS概率与某个阈值P LOS进行比较从而对信道进行LOS/NLOS判决得到的，即当LOS概率大于或等于P LOS时判决为LOS信道，如比特位为1指示终端设备与接入网设备之间信道为LOS信道。当LOS概率低于P LOS时判决为NLOS信道，如比特位为0指示终端设备与接入网设备之间信道为NLOS信道。上报LOS判决结果，能够有效降低物理层上报的比特开销，降低系统的负载，同时指示定位服务器当前信道最基本的LOS状态。LOS置信度与LOS概率类似，也是基于参考信号对信道进行LOS检测后，确定的当前LOS信道的一种度量指标，LOS置信度越高，表示信道越有可能为LOS的，LOS置信度越低，表示信道越有可能为NLOS的。LOS质量是基于参考信号对信道进行LOS检测后，确定的当前LOS信道的一种度量指标，质量越高代表LOS概率越大，信道越有可能为LOS信道，质量越低LOS概率越小，信道越有可能为NLOS信道。本申请在此仅做示意性说明并不具体限定LOS状态信息的确定方式。
在一种可选的实施方式中，LOS状态信息包括：终端设备和各接入网设备间信道的质量参数；质量参数包括以下中的一种或多种：信道增益、方差以及标准差。
需要说明的是，质量参数可以反馈终端设备与接入网设备之间的信道状况，可间接反馈LOS状态，如，信道增益、方差以及标准差，其中信道增益是指接收到的参考信号的功率除以参考信号的发射功率得到的结果。方差是指基于参考信号估计得到的当前信道系数的方差大小。标准差是指信道系数方差的正平方根值。若终端设备与接入网设备间的质量参数为信道增益，若信道增益的值超过信道增益的门限值，则可以确定信道的质量很好，只有在LOS信道状态下，信道增益才能超过门限值，因此可以确定该终端设备与接入网设备间的信道为LOS。本申请在此仅以质量参数为信道增益、方差以及标准差进行示意性描 述，但是在实际应用时，并不限定具体为哪些参数。
在一种可选的实施方式中，终端设备可发送定位配置请求信息至定位服务器；并接收来自定位服务器的定位参考信号配置信息以及LOS检测配置信息；LOS检测配置信息包括以下中的一种或多种：LOS检测算法、LOS检测的接入网设备指示信息、LOS检测的定位参考信号的指示信息。
需要说明的是，定位参考信号的配置信息包括定位参考信号的时域资源配置信息，也即定位参考信号在哪个时域资源发送，以便终端设备可以在对应的时域资源下接收定位参考信号。通过LOS检测配置信息可以指示终端设备到底采用什么算法进行LOS检测，到底检测哪些接入网设备与终端设备之间的信道，以及具体上报哪些信息等。本申请在此仅作示例性描述，并不具体限定LOS检测配置信息中具体包括哪些信息，例如，LOS检测时采用的算法可能包括一致性分析算法、基于神经网络模型的检测算法等，定位服务器可通过LOS检测配置信息指示终端设备采用一致性分析算法进行LOS检测。其中，LOS检测的接入网设备指示信息可通过接入网设备的标识指示，LOS检测的定位参考信号的指示信息可通过参考信号的标识进指示。终端设备具体检测哪些接入网设备的信道，可根据LOS检测配置信息中的接入网设备的标识确定，还可以通过参考信号的标识确定，本申请在此不作具体限定。
在一种可选的实施方式中，终端设备可接收来自服务接入网设备的指示信息；指示信息用于指示终端设备进行定位测量和LOS检测。
需要说明的是，指示信息可能是通过下行控制信息，或媒体接入控制层(media access control，MAC)，或无线资源控制(radio resource control，RRC)发送的。
在一种可选的实施方式中，接收来自定位服务器的第一LOS检测触发状态，LOS检测配置信息与LOS检测触发状态存在对应关系；根据第一LOS检测触发状态LOS检测触发状态的状态值以及对应关系，确定第一LOS检测触发状态对应的第一LOS检测配置信息；通过第一LOS检测配置信息对一个或多个接入网设备的定位参考信号进行检测，确定一个或多个定位测量结果分别对应的LOS状态信息。
需要说明的是，LOS检测配置信息可能包括多种，通过LOS检测触发状态可以使得终端设备可以明确知道具体采用哪种LOS检测配置信息对终端设备与接入网设备之间的信道进行检测，还要说明的是，终端设备可按照第一LOS检测配置信息对终端设备与接入网设备之间的信道均进行检测，也可仅仅按照第一LOS检测配置信息检测部分终端设备与接入网设备之间的信道，本申请在此不作具体限定。
在一种可选的实施方式中，终端设备发送终端设备的LOS检测能力信息至定位服务器；LOS检测能力信息包括以下中的一种或多种：终端设备在单频点或多频点是否支持LOS检测、终端设备在单频点或多频点支持LOS检测的最大信道数量、终端设备支持的LOS检测算法以及终端设备支持的LOS检测算法的置信度。
需要说明的是，终端设备可以主动发送LOS检测能力信息给定位服务器，也可以在定位服务器向终端设备发送请求时，向定位服务器发送LOS检测能力信息，具体是哪种情况本申请在此不具体限定。
第二方面，本申请提供一种定位信息上报方法，该方法可通过服务接入网设备来执行，服务接入网设备可接收来自终端设备的定位测量信息；定位测量信息包括：终端设备基于定位参考信号确定的一个或多个定位测量结果和分别与一个或多个定位测量结果对应的 LOS状态信息；发送定位测量信息至定位服务器。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。其中，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
图1示例性地提供一种定位系统架构的示意图，涉及的网元/模块主要包括下一代无线接入网络(next generation radio access network，NG-RAN)、终端和核心网三部分。
其中，核心网包括定位管理功能(location management function，LMF)、移动性管理功能(access and mobility management function，AMF)。定位服务器即LMF连接到AMF，LMF和AMF之间通过NL1接口连接。LMF负责支持有关终端的不同类型的位置服务，包括对终端的定位和向终端传递辅助数据。AMF可以从第5代核心网络位置服务(5th generation core network location services，5GC LCS)实体接收与终端相关的位置服务请求，或者AMF本身也可代表特定终端启动一些位置服务，并将位置服务请求转发给LMF。AMF得到终端返回的位置信息，将位置信息返回给5GC LCS实体。
NG-RAN可以包括gNB、下一代演进型基站(next generation evolved nodeB，ng-eNB)等。gNB、ng-eNB之间通过Xn接口连接，AMF与ng-eNB/gNB通过NG-C接口连接。
终端可以测量来自NG-RAN的下行信号以支持定位。gNB/ng-eNB可以为终端提供定位测量信息，并将此定位测量信息传达给终端。
LMF和终端可能进行的信息交互包括以下几种：1)LMF与ng-eNB/gNB之间通过NR定位协议a(NR positioning protocol a，NRPPa)消息进行信息交互，例如获取定位参考信号(positioning reference signals，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)LMF与终端之间通过长期演进(long term evolution，LTE)定位协议(LTE positioning protocol，LPP)消息进行终端能力信息传递、辅助信息传递、定位测量信息传递等。
需要说明的是，本申请并不限定于图1所示的系统架构，还可以应用于未来其它的通信系统，例如第六代(the 6th generation，6G)通信系统架构等。并且，本申请所涉及网元，在未来通信系统中，可能保持功能相同，但名称会改变。
本申请实施例中所涉及的终端设备，又可以称之为终端，是用户侧的一种用于接收或发射信号的实体，用于向网络设备发送上行信号，或从网络设备接收下行信号。包括向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端设备可以包括用户设备(user equipment，UE)、V2X终端设备、无线终端设备、移动终端设备、设备到设备通信(device-to-device，D2D)终端设备、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)终端设备、物联网(internet of things，IoT)终端设备、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)、可穿戴设备、车载设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智 能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
而如上介绍的各种终端设备，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。
本申请实施例中所涉及的核心网，可以包括对用户的信令和数据进行处理和转发的网络设备。例如，包括AMF、会话管理功能(session management function，SMF)以及用户面网关等核心网设备。其中用户面网关可以是具有对用户面数据进行移动性管理、路由、转发等功能的服务器，一般位于网络侧，如服务网关(serving gateway，SGW)或分组数据网络网关(packet data network gateway，PGW)或用户面网元功能实体(user plane function，UPF)等。AMF以及SMF相当于LTE系统中的移动管理实体(mobility management entity，MME)。AMF主要负责准入方面，SMF主要负责会话管理。当然，核心网中也可以包括其他网元，这里不一一列举。
本申请实施例中所涉及的NG-RAN，可以包括一个或多个接入网设备。NG-RAN中的接入网设备又可以称为基站，或者RAN节点，或者RAN设备。接入网设备是网络侧的一种用于发射和/或接收信号的实体，作为终端与接入网的其余部分之间的路由器，其中接入网的其余部分可以包括网际互连协议(internet protocol，IP)网络等。接入网设备还可以协调对空中接口的属性管理。例如，接入网设备可以是LTE中的演进型基站(evolutional Node B，eNB或e-NodeB)，eNB是一种部署在无线接入网中满足4G标准的为终端提供无线通信功能的装置。接入网设备还可以是新无线控制器(new radio controller，NR controller)，可以是5G系统中的gNode B(gNB)，可以是集中式网元(centralized unit)，可以是新无线基站，可以是射频拉远模块，可以是微基站(也称为小站)，可以是中继(relay)，可以是分布式网元(distributed unit)，可以是各种形式的宏基站，可以是TRP、传输测量功能(transmission measurement function，TMF)或传输点(transmission point，TP)或者任何其它无线接入设备，或者下一代通信中的基站，但本申请实施例不限于此。
在应用图1所示的定位架构时，可能存在图2示出的定位场景，该定位场景中包括：多个基站gNB1～gNB6、UE、LMF以及服务基站gNB-s。图中仅作示意性描述，但是在实际应用时，并不具体限定基站的数量。需要说明的是，在实际应用时，UE只有对来自至少3个基站的定位参考信号进行解算才能确定UE的位置。图中的gNB1～gNB6可分别向UE发送定位参考信号PRS1、PRS2、PRS3、PRS4、PRS5以及PRS6，UE可基于定位参考信号，测量不同基站与UE的距离，之后根据已知的基站位置，则可解算出UE的位置。终端设备可将解算的位置信息反馈给gNB-s，并通过gNB-s反馈给LMF。此外，图2中示意的UE与gNB之间存在障碍物，也即UE与gNB之间的路径为NLOS。
需要说明的是，服务基站可以为UE提供通信服务，如：UE可通过服务基站接收来自其他UE的消息，或者UE可通过服务基站转发消息，本申请在此不限定服务基站可以为UE提供哪些通信服务。在实际应用时，服务基站可以为gNB1～gNB6中的一个，也即服务 基站也可向UE发送定位参考信号。亦或者如图2所示，服务基站与gNB1～gNB6相互独立，服务基站并不向UE发送定位参考信号，在此仅接收来自UE的定位测量信息。无论服务基站是上述哪种情况的基站均适用于本申请的方案。
接下来参考图3具体介绍本申请提供的定位流程，定位需要接入网设备、服务接入网设备、终端设备以及定位服务器的交互来实现，图3中以UE示意终端设备，以gNB1、gNB2示意接入网设备，以gNB-s示意服务接入网设备，以LMF示意定位服务器，但是在实际应用时并不限定接入网设备的数量，图3以服务接入网设备也向终端设备发送定位参考信号进行示意，在具体执行时，可执行如下：
301A，gNB1发送定位参考信号1至UE。
301B，gNB2发送定位参考信号2至UE。
301C，gNB-s发送定位参考信号3至UE。
相应地，UE会分别接收来自gNB1、gNB2以及gNB-s的定位参考信号定位参考信号1、定位参考信号2以及定位参考信号3。
302，UE基于定位参考信号1确定定位测量信息1，基于定位参考信号2确定定位测量信息2以及基于定位参考信号3确定定位测量信息3。
其中，一个定位测量结果是终端设备根据一个接入网设备发送的定位参考信号确定的，且该定位测量结果对应一个LOS状态信息，该LOS状态信息可以指示定位测量结果是LOS的还是NLOS的。其中，定位测量结果可通过TOA，和/或，到达角度来指示，当然也可通过其他指标来指示，本申请在此不作具体限定。LOS状态信息可以指示定位测量结果是LOS的还是NLOS的。如：定位测量信息1中包括UE对定位参考信号1测量得到的TOA、到达角度，以及UE对定位参考信号1进行检测得到的LOS状态信息。
需要说明的是，终端设备可通过第一算法确定终端设备与接入网设备间的定位测量结果。其中，第一算法可以为最大似然估计算法，还也可以为MUSIC算法等，本申请在此不具体限定。其中，最大似然估计算法也即通过将本地生成的定位参考信号与接收到的定位参考信号进行相关运算，大于阈值的所有峰值点对应的时间即为定位参考信号通过不同径的到达时间，第一个峰值点到达时间即为LOS径的TOA。MUSIC算法是一种基于矩阵特征空间分解的方法，将观测到的参考信号的自相关矩阵分解为信号子空间和噪声子空间，并构建空间谱，空间谱的谱峰对应的TOA值即为测量值。
终端设备可通过第二算法对终端设备与接入网设备间的信道进行LOS状态检测。其中，第二算法可以为一致性分析算法，还可以为基于AI的算法。其中，一致性分析算法是通过检测不同的天线单元下，终端设备的信号强度波动情况，来确定LOS状态，例如，若终端设备的信号强度波动小，则认为定位测量信息为LOS；若终端设备的信号强度波动大，则认为定位测量信息为NLOS。其中，基于AI的算法也即利用神经网络基于终端与各接入网间的历史信道数据进行神经网络模型的训练，在进行LOS判断时，直接输入估计得到的信道系数或者是接收到的参考信号输入神经网络模型，输出LOS检测结果。
此外还可根据其他方式确定位测量结果和LOS状态信息，在此不一一示意，凡是可以基于定位参考信号，确定定位测量结果和LOS状态信息的方法均适用于本申请。
303，UE发送定位测量信息1、定位测量信息2以及定位测量信息3至gNB-s。
304，gNB-s发送定位测量信息1、定位测量信息2以及定位测量信息3至LMF。
本申请实施例中，终端设备在进行定位时反馈的LOS状态信息可以指示定位测量结果 是LOS的还是NLOS的，在定位时，定位服务器根据定位测量结果对应的LOS状态信息可以获悉哪个定位测量结果是可靠的，便于更加精确地确定终端设备的位置。
在一种可选的方式中，LOS状态信息可通过不同的方式来指示，具体如下：
方式1，LOS状态信息为多个，将多个定位测量结果按照对应的LOS概率进行排序，通过排序指示一个或多个定位测量结果对应的LOS状态信息通过排序进行指示。需要说明的是，终端设备对定位测量结果按照对应的LOS概率进行排序，能够隐式的指示各个测量量之间的LOS概率大小的相对关系，能够节省额外的LOS状态信息比特(也即节省非隐士指示占用的信息比特数)，同时达到指示定位服务器各测量量的权重大小，提升定位精度的目的。
此外，终端设备在接收到来自多个接入网设备的定位参考信号时，可基于多个定位参考信号确定多个定位测量结果，不同的定位测量结果对应的LOS概率是不同的，终端设备可以与服务接入网设备提前约定仅仅上报LOS概率排序靠前的几个定位测量结果。
方式2，LOS状态信息包括：终端设备与接入网设备间信道的LOS判决结果或LOS概率；LOS状态信息可通过一个或多个比特位指示。
需要说明的是，LOS状态信息仅仅是示意性说明，LOS状态信息可指示终端设备与接入网设备之间信道是LOS还是NLOS，在实际应用中LOS状态信息还可称为LOS结果，LOS状态等，LOS状态信息也可以包含其它名称的LOS信道指示信息，本申请在此并不具体限定。本申请中除了可包括上述提及的LOS判决结果、LOS概率以外还可以包括LOS质量、LOS置信度等，另外上述提及的LOS状态信息也不仅仅为终端设备与接入网设备之间信道的LOS情况，还可以是终端设备与接入网设备之间信道的NLOS情况，也即LOS状态信息可以为终端设备与接入网设备间信道的NLOS判决结果或NLOS概率等，本申请在此并不具体限定。
其中，LOS概率是通过LOS检测算法(例如一致性分析算法)对终端设备和接入网设备间的信道进行LOS检测计算得到的，上报LOS概率(可对LOS概率量化后上报)能够指示信道LOS状态信息，有利于提升定位精度。LOS判决结果是通过将LOS概率与某个阈值PLOS进行比较从而对信道进行LOS/NLOS判决得到的，即当LOS概率大于或等于PLOS时判决为LOS信道，如比特位为1指示终端设备与接入网设备之间信道为LOS信道。当LOS概率低于PLOS时判决为NLOS信道，如比特位为0指示终端设备与接入网设备之间信道为NLOS信道。上报LOS判决结果，能够有效降低物理层上报的比特开销，降低系统的负载，同时指示定位服务器当前信道最基本的LOS状态。LOS置信度与LOS概率类似，也是基于参考信号对信道进行LOS检测后，确定的当前LOS信道的一种度量指标，LOS置信度越高，表示信道越有可能为LOS的，LOS置信度越低，表示信道越有可能为NLOS的。LOS质量是基于参考信号对信道进行LOS检测后，确定的当前LOS信道的一种度量指标，质量越高代表LOS概率越大，信道越有可能为LOS信道，质量越低LOS概率越小，信道越有可能为NLOS信道。本申请在此仅做示意性说明并不具体限定LOS状态信息的确定方式。
此外，LOS概率，LOS质量，LOS置信度等可通过LOS检测算法对终端与接入网设备间的信道进行LOS检测确定，LOS判决结果可通过将LOS概率，或者LOS质量，LOS置信度等与预设阈值进行大小比较确定的，本申请在此仅做示意性说明并不具体限定LOS 状态信息的确定方式。在实际应用时，服务接入网设备与终端设备可约定选择其中的一种或多种来指示LOS状态信息，如，通过LOS判决结果指示LOS状态信息，或通过LOS判决结果以及LOS概率共同指示LOS状态信息。
还需要说明的是，LOS的状态信息可通过1个比特位来指示，也可以通过多个比特位来指示，在实际应用时，服务接入网设备与UE可约定选择几个比特位来指示LOS状态信息，本申请在此不做具体限定。如表1所示，若LOS状态信息为LOS判决结果，可通过1比特进行指示，如比特位显示为1则指示定位测量结果对应的LOS的状态信息为LOS，比特位显示为0则指示定位测量结果对应的LOS的状态信息为NLOS。如，UE对来自gNB1的PRS1测量确定的定位测量结果为A，对应的比特位取值为0，可知，UE与gNB1间信道为NLOS的。

上述表1中LOS判决结果是通过一个比特位指示，但是在实际应用时也可通过多个比特位来指示LOS判决结果，本申请在此不作具体限定。
方式3，LOS状态信息包括：终端设备和接入网设备间信道的质量参数；质量参数包括以下中的一种或多种：信道增益、方差以及标准差。
需要说明的是，质量参数可以反馈终端设备与接入网设备之间的信道状况，可间接反馈LOS状态，如，信道增益、方差以及标准差，其中信道增益是指接收到的参考信号的功率除以参考信号的发射功率得到的结果。方差是指基于参考信号估计得到的当前信道系数的方差大小。标准差是指信道系数方差的正平方根值。若终端设备与接入网设备间的质量参数为信道增益，若信道增益的值超过信道增益的门限值，则可以确定信道的质量很好，只有在LOS信道状态下，信道增益才能超过门限值，因此可以确定该终端设备与接入网设备间的信道为LOS。本申请在此仅以质量参数为信道增益、方差以及标准差进行示意性描述，但是在实际应用时，并不限定具体为哪些参数。
为了更好地说明本申请的方案，接下来通过具体示例分情况来说明本申请终端设备可能如何上报定位测量结果和LOS状态信息。下述提及的上报定位测量结果和LOS状态信息的方式仅作示例性描述，并不具体限定终端设备的上报方法，在实际应用中，可能还涉及其他上报方法或指示LOS状态信息的方式，本申请在此不作具体限定，凡是涉及上报方法和指示LOS状态信息的方式均适用于本申请。
假定在图2的基础上，若UE根据上述提及任一LOS检测算法中的一种或多种分别确定出，UE与gNB1，gNB2，gNB3，gNB4，gNB5，gNB6之间的LOS概率，假定UE计算得到的LOS概率如下；UE-gNB1：0.95；UE-gNB2：0.88；UE-gNB3：0.92；UE-gNB4：0.12；UE-gNB5：0.96；UE-gNB6：0.06。由于物理层首先上报比特量，具体可在该示例的基础上参照如下情况进行上报，具体如下：
情况1：UE上报所有基站的测量结果以及对应的LOS概率。当然情况1在此仅仅是 示例性说明，并不具体限定如何上报所有基站的测量结果以及对应的LOS概率。
UE基于来自6个gNB的定位参考信号确定6个定位测量结果，如表2所示，UE对来自gNB1的PRS1测量确定的定位测量结果为A，LOS概率为0.95；UE对来自gNB2的PRS2测量确定的定位测量结果为B，LOS概率为0.88；UE对来自gNB3的PRS3测量确定的定位测量结果为C，LOS概率为0.92；UE对来自gNB4的PRS4测量确定的定位测量结果为D，LOS概率为0.12；UE对来自gNB5的PRS5测量确定的定位测量结果为E，LOS概率为0.96；UE对来自gNB6的PRS6测量确定的定位测量结果为F，LOS概率为0.06；UE可如表2所示上报所有的定位测量结果以及各测量结果对应的LOS概率。
另外，LOS概率越大表示定位测量结果可靠性越高，定位测量结果受到NLOS的干扰越小，LOS概率越小表示定位测量结果越不可靠，定位测量结果受到NLOS的干扰越大。

在上述情况1～情况5中，UE在根据LOS概率排序上报定位测量结果时，LMF收到定位测量结果后可根据定位测量结果的排序情况对不同的定位测量结果进行加权计算从而解算出UE的位置信息。
需要说明的是，定位服务器可选择LOS状态信息均为LOS的定位测量结果解算终端设备的位置信息。但是，在实际应用时，由于LOS状态信息的判定可能存在误判的情况，故而在定位服务器可按照LOS概率对不同的测量量加权计算从而解算出终端设备的位置信息以规避这种LOS误判的情况，如，定位测量结果1对应的LOS概率为0.1，定位测量结果2对应的LOS概率为0.9，在解算终端设备的位置时可通过f(测量结果1对应的权重 值*0.1+测量结果2对应的权重值*0.9)来确定，其中，f为终端解算函数。
此外，定位服务器也可以按照LOS概率，选取部分测量量进行定位终端的位置解算，如定位测量结果1对应的LOS概率为0.3，定位测量结果2对应的LOS概率为0.9，定位测量结果3对应的LOS概率为0.8，定位测量结果4对应的LOS概率为0.9。定位服务器在解算终端设备的位置时，定位服务器可选取LOS概率大于0.8的测量结果2，测量结果3，测量结果4，通过终端解算函数来解算除终端设备的位置。
当然上述情况1～情况5中的LOS概率也可以为NLOS概率，本申请在此不具体定，UE上报LOS概率时可以通过量化的形式上报，如将0～1量化为16个等级，通过4比特进行指示，如表11所示。其中，1111指示LOS概率的取值范围为15/16-1，0000则指示LOS概率的取值范围为0-1/16。1110指示LOS概率的取值范围为14/16-15/16等，本申请在此不一一示意。例如，UE上报LOS概率为0.95的定位测量结果A时，可上报1111，由于0.95位于15/16-1的范围内。在此仅作举例说明，并不一一示意。
