Description

定位方法、装置及系统 技术领域
本申请涉及定位技术领域，尤其涉及定位方法、装置及系统。
背景技术
现有的定位方法主要包括基于用户设备(user equipment，UE)(UE-based)的定位方法、用户设备辅助(UE-assisted)定位方法和独立(standalone)定位方法。其中，UE-based定位方法为在有辅助数据的情况下，UE不仅负责提供测量结果，还负责基于测量结果和辅助数据进行位置计算。UE-assisted定位方法为在有辅助数据的情况下，UE仅负责提供测量结果，不执行位置计算，由定位管理功能(location management function，LMF)网元基于测量结果和辅助数据执行位置计算。standalone定位方法为UE在没有网络辅助数据的情况下执行测量和位置计算。可以看出，辅助数据可以辅助LMF网元或者UE执行位置计算。
目前，针对下行链路-离开角(downlink-angle of departure，DL-AoD)的定位方法，一种方案是无线接入网络(radio access network，RAN)2#108次会议上达成的一个结论：在用于执行位置计算的辅助数据中包含定位参考信号(positioning reference signal，PRS)资源的空间方向信息，例如方位角、仰角或者波束宽度。然而，根据该方案中的辅助信息只能估计出角度(离开角/到达角)的一个大致范围，无法实现高精度定位。为了实现高精度定位目标，需要设计新的辅助数据以进行精确的角度估计。
发明内容
本申请实施例提供定位方法、装置及系统，用于解决基于现有的辅助数据只能估计出角度(离开角/到达角)的一个大致范围，无法实现高精度定位的问题。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种定位方法，执行该方法的通信装置可以为定位管理设备也可以为应用于定位管理设备中的模块，例如芯片或芯片系统。下面以执行主体为定位管理设备为例进行描述。定位管理设备从一个或多个接入网设备获取多个辅助数据，该多个辅助数据中的每个辅助数据包括与一个或多个预设角度对应的一组或多组映射关系，其中，该一组或多组映射关系中的每组映射关系分别与该一个或多个预设角度中的一个预设角度对应，该每组映射关系均包括一个或多个定位参考信号PRS资源标识中的每个PRS资源标识和该每个PRS资源标识在相应预设角度上对应的功率信息的映射关系；定位管理设备从终端设备获取多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息；定位管理设备根据该多个辅助数据以及该多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息，对该终端设备定位。
目前，基于现有的辅助数据只能估计出角度(离开角/到达角)的一个大致范围， 无法实现高精度定位。基于本申请实施例提供的定位方法，由于本申请实施例中的辅助数据包括与一个或多个预设角度对应的一组或多组映射关系，其中，一组或多组映射关系中的每组映射关系分别与一个或多个预设角度中的一个预设角度对应，每组映射关系均包括一个或多个PRS资源标识中的每个PRS资源标识和每个PRS资源标识在相应预设角度上对应的功率信息的映射关系。因此定位管理设备根据多个辅助数据以及多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息，可以进行准确的待测角度(如离开角/到达角)估计，进而可以实现高精度定位。
结合上述第一方面，在一种可能的实现方式中，定位管理设备根据该多个辅助数据以及该多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应角度上对应的功率信息，对该终端设备定位，包括：定位管理设备根据该多个辅助数据以及该多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应角度上对应的功率信息，确定该多个待测角度；定位管理设备根据该多个待测角度，以及该多个待测角度中每个待测角度对应的接入网设备的位置信息，对该终端设备定位。

目前，基于现有的辅助数据只能估计出角度(离开角/到达角)的一个大致范围，无法实现高精度定位。基于本申请实施例提供的定位方法，由于本申请实施例中的辅助数据包括与一个或多个预设角度对应的一组或多组映射关系，其中，一组或多组映射关系中的每组映射关系分别与一个或多个预设角度中的一个预设角度对应，每组映射关系均包括一个或多个PRS资源标识中的每个PRS资源标识和每个PRS资源标识在相应预设角度上对应的功率信息的映射关系。因此定位管理设备根据多个辅助数据以及多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息，可以进行准确的角度(如离开角/到达角)估计，进而可以实现高精度定位。

具体实施方式
为了方便理解本申请实施例中的方案，首先给出相关技术的简要介绍或定义如下：
第一，辅助数据
辅助数据可以在UE-assisted定位方法中辅助LMF网元进行位置计算，或者辅助数据可以在UE-based定位方法中辅助UE进行位置计算。以UE-assisted定位方法为例，基站和/或UE需要传输辅助数据给LMF网元，以协助LMF网元进行位置计算。其中，辅助数据的内容取决于基站和UE的能力。以DL-AoD定位方法为例，辅助数据可以分为以下几类：
测量辅助数据：包括定位参考信号(positioning reference signal，PRS)配置信息等。
计算辅助数据：包括PRS资源标识(resource ID)，发送/接收点(transmission-reception point，TRP)的地理坐标，TRP的定时信息等。
第二，离开角(angle of departure，AoD)
离开角的方位角(azimuth angle of departure，AOD)和离开角的天顶角(zinth angle of departure)是基于角度的定位方法中重要的角度信息。如图1所示，离开角的方位角和离开角的天顶角都是关于离开角(从基站处发送到用户的无线信号)的信息。其中，离开角的方位角是与正北方向的夹角(顺时针方向为正)，离开角的天顶角是与天顶方向的夹角。如果获得基站的坐标信息以及离开角的方位角和离开角的天顶角的信息，就可以计算出用户的位置(三维)。为了表述方便，本申请实施例中，将离开角的方位角和离开角的天顶角统称为离开角，以下的AOD也指代离开角，不再进行细分，在此统一说明，以下不再赘述。
第三，DL-AOD定位方法
基于DL-AOD的定位方法主要依赖于来自多个TRP的角度估计信息，包括以下两个步骤：
1、角度测量和报告；
2、位置计算。
如图2所示，对于某个特定的AOD，UE可以通过波束扫描的方式扫描每个波束(beam)，测量得到每个波束的波束增益(相当于该AOD对应的指纹)。通过遍历AoD的取值，可以形成一个波束图案(beam pattern)，如图3中的左图所示。例如，当AoD为30度时，从beam#1，beam#2和beam#3处测量得到的波束增益分别为-11dB，-5.3dB和9dB。为了消除未知路径损耗，可以对波束增益进行归一化处理，其中，归一化处理之后这三个波束的相对增益如图3中的右图所示，可以看作当AoD为30度时的相对增益包络。进一步的，根据从每个beam处测得的波束增益，可以使用最大似然(maximum likelihood)算法选择与相对增益包络(相当于预存的角度指纹库)最佳匹配的角度来估计对应的AoD的取值。示例性的，本申请实施例中的波束增益例如可以为参考信号接收功率(reference signal received power，RSRP)。
进一步的，如果获得TRP的地理坐标信息以及AoD的取值，就可以估算出用户的位置。图4给出了一个二维平面中的DL-AOD定位方法示意图。通过上述方法估计出的角度信息(AoD 1。AoD 2)、TRP1的地理坐标信息(X 1，Y 1)、以及TRP2的地理坐标信息(X 2，Y 2)，根据三角形的相关理论可以通过求解以下公式(1)的方程可以得到UE的位置坐标(a，b)。

虽然在上述方案中，在用于执行位置计算的辅助数据中包含PRS资源的空间方向信息，例如方位角、仰角或者波束宽度。然而，该方案中的辅助信息只能提供粗粒度的角度范围，无法实现高精度定位。为了实现Rel-17的高精度定位目标，需要设计新的辅助数据以进行精确的角度估计。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等，本申请中涉及的5G移动通信系统包括非独立组网(non-standalone，NSA)的5G移动通信系统或独立组网(standalone，SA)的5G移动通信系统。本申请提供的技术方案还可以应用于未来的通信系统，如第六代移动通信系统。通信系统还可以是陆上公用移动通信网(public land mobile network，PLMN)网络、设备到设备(device-to-device，D2D)通信系统、机器到机器(machine to machine，M2M)通信系统、物联网(Internet of Things，IoT)通信系统或者其他通信系统。

其中，定位管理设备从一个或多个接入网设备获取多个辅助数据，多个辅助数据中的每个辅助数据包括与一个或多个预设角度对应的一组或多组映射关系，其中，一组或多组映射关系中的每组映射关系分别与一个或多个预设角度中的一个预设角度对应，每组映射关系均包括一个或多个PRS资源标识中的每个PRS资源标识和每个PRS资源标识在相应预设角度上对应的功率信息的映射关系；以及，定位管理设备从终端设备获取多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息，进而，定位管理设备根据多个辅助数据以及多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息，对终端设备定位。该方案的详细实现将在后续方法实施例中描述，在此不予赘述。
目前，基于现有的辅助数据只能估计出角度(离开角/到达角)的一个大致范围，无法实现高精度定位。基于本申请实施例提供的通信系统，由于本申请实施例中的辅助数据包括与一个或多个预设角度对应的一组或多组映射关系，其中，一组或多组映射关系中的每组映射关系分别与一个或多个预设角度中的一个预设角度对应，每组映射关系均包括一个或多个PRS资源标识中的每个PRS资源标识和每个PRS资源标识在相应预设角度上对应的功率信息的映射关系。因此定位管理设备根据多个辅助数据以及多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对 应的功率信息，可以进行准确的待测角度(如离开角/到达角)估计，进而可以实现高精度定位。
可选的，本申请实施例中的定位管理设备可以是LMF网元或者定位管理组件(location management component，LMC)网元，或者可以是位于网络设备中的本地定位管理功能(local location management function，LLMF)网元。

示例性的，图7为在5G移动通信系统中应用本申请实施例的定位方法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6的定位管理功能的装置或组件(比如LMF网元)部署在核心网中，图7的定位管理功能的装置或组件(比如LMC网元)可以部署在NG-RAN设备中。如图7所示，gNB中包含LMC网元。LMC网元是LMF网元的部分功能组件，可以集成在NG-RAN设备的gNB中。

需要说明的是，表十一示例性的以功率值降序排列之后，前一个功率值与后一个功率值相除为例进行说明。当然，也可以将功率值降序排列之后，后一个功率值与前一个功率值相除；或者，还可以是功率值升序排列之后，前一个功率值与后一个功率值相除；或者，还可以是功率值升序排列之后，后一个功率值与前一个功率值相除，本申请实施例对此不作具体限定。
应理解，在上述场景四中，采用上述差分法或商分法确定每个PRS资源标识在相应预设角度上对应的功率值以前一个功率值为基准的相对值之后，辅助数据中的各组映射关系出现的先后顺序，也应该是根据功率值的排序结果呈现。即，以上述表十为例，辅助数据在传输时的各组映射关系呈现的先后顺序可以如表十二所示，这样方便后续各个PRS资源标识在相应预设角度上对应的功率值的依次还原，在此统一说明，以下不再赘述。

AOD#2＝4° ID2 1
AOD#1＝2° ID1 2

应理解，上述仅是示例性的提供几种将每个PRS资源标识在相应预设角度上对应的功率值执行压缩的方式，并不构成对本申请实施例提供的技术方案的限定。本领域技术人员可以理解，还可能存在其他压缩方式，使得将上述辅助数据执行压缩之后，在辅助数据的传输过程中可以减少信令开销，本申请实施例对此不作具体限定。
应理解，在存在多种压缩方式的情况下，可以根据多个PRS资源标识在相应预设角度上对应的功率值的分布情况或者压缩需求选择不同的压缩方法，每种压缩方法可以多次使用或者混合使用。例如，差分法或商分法适用于数值之间相差比较大的情况，因为这样可以得到更小的压缩数值，从而更大程度的减少信令开销。
应理解，一个或多个PRS资源标识在相应预设角度上对应的功率值在相应预设角度下执行排序的方案中，在传输辅助数据的同时，可以不用传输上述第一功率值，因为执行定位的设备(如本申请下述实施例中的LMF网元)在确定多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息时，可以按照同样的方式将一个或多个PRS资源标识在相应待测角度上对应的功率值在相应待测角度下执行排序后，根据排序结果确定即可。而一个或多个PRS资源标识在相应预设角度上对应的功率值在所有预设角度下执行排序的方案中，在传输辅助数据的同时，需要传输上述第二功率值，因为执行定位的设备在确定多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息时，需要参考第二功率值才能确定；或者，执行定位的设备需要根据第二功率值才能进行所有待测角度下各个PRS资源标识在相应待测角度上对应的功率值的还原，本申请实施例对此不作具体限定。
可选的，本申请实施例中，每组映射关系中包括的一个或多个PRS资源标识为在相应预设角度上需要测量的全部PRS资源的PRS资源标识；或者，每组映射关系中包括的一个或多个PRS资源标识为在相应预设角度上需要测量的部分PRS资源的PRS资源标识。
其中，相比于每组映射关系中包括的一个或多个PRS资源标识为在相应预设角度上需要测量的全部PRS资源的PRS资源标识的情况，每组映射关系中包括的一个或多个PRS资源标识为在相应预设角度上需要测量的部分PRS资源的PRS资源标识的情况可以在一定程度上减少辅助数据的数据量，因此在辅助数据的传输过程中可以减少信令开销，从而可以降低定位时延和功耗。相比于每组映射关系中包括的一个或多个PRS资源标识为在相应预设角度上需要测量的部分PRS资源的PRS资源标识的情况，每组映射关系中包括的一个或多个PRS资源标识为在相应预设角度上需要测量的全部PRS资源的PRS资源标识的情况可以提高角度估计的准确性，从而更大程度的提高定位精确性。
一种可能的实现方式中，若在相应预设角度上需要测量的全部PRS资源的PRS资源标识对应的功率值是降序排列的，则部分PRS资源包括排序后的前M个功率值 对应的PRS资源，M为大于1的正整数。
示例性的，假设在相应预设角度上需要测量的全部PRS资源的PRS资源标识对应的功率值如表二所示，M＝3，则假设每个PRS资源标识在相应预设角度上对应的功率信息包括每个PRS资源标识在相应预设角度上对应的功率值，则本申请实施例提供的辅助数据可以如表十三所示：

当然，若每个PRS资源标识在相应预设角度上对应的功率信息包括将每个PRS资源标识在相应预设角度上对应的功率值执行压缩后的数值，则本申请实施例提供的辅助数据为将在相应预设角度上需要测量的全部PRS资源的PRS资源标识对应的功率值是降序排列之后得到的前M个功率值执行压缩后的数值，相应的压缩方法可参考上述实施例，在此不再赘述。

示例性的，一个或多个PRS资源标识中的每个PRS资源标识分别在一个或多个预设角度上对应的功率值可以如上述表二所示。
其中，当一组或多组映射关系中的每个PRS资源标识在相应预设角度上对应的功率信息包括每个PRS资源标识在相应预设角度上对应的功率值时，NG-RAN设备根据一个或多个PRS资源标识中的每个PRS资源标识分别在一个或多个预设角度上对应的功率值，建立辅助数据具体包括：NG-RAN设备建立与一个或多个预设角度对应的一组或多组映射关系，其中，一组或多组映射关系中的每组映射关系分别与一个或多个预设角度中的一个预设角度对应，每组映射关系均包括一个或多个PRS资源标识中的每个PRS资源标识和每个PRS资源标识在相应预设角度上对应的功率值的映射关系。

可选的，本申请实施例中，NG-RAN设备可以定期更新上述辅助数据。比如，根据近期从不同终端设备分别获取的一个或多个PRS资源标识中的每个PRS资源标识分别在一个或多个预设角度上对应的功率值，更新上述辅助数据。其中，通过定期更新上述辅助数据，可以确保辅助数据的准确性，进而可以提高后续待测角度估计的准确性，从而更大程度的提高定位精确性。

应理解，在存在多个待测角度和多个辅助数据的情况下，任意一个待测角度均为某个接入网设备的PRS资源(波束)与终端设备接收波束之间的角度，则将该待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息与相应的辅助数据中包括的与一个或多个角度对应的一组或多组映射关系进行匹配时，相应的辅助数据应该理解为通过该接入网设备建立的辅助数据。比如，图9中的NG-RAN设备与终端设备之间的待测角度对应的辅助数据为通过图9中的NG-RAN设备建立的辅助数据，在此统一说明，以下不再赘述。
可选的，上述步骤S910-S911中以终端设备确定多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息，进而LMF网元根据多个辅助数据以及多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息，确定多个待测角度为例进行说明。当然，在辅助数据压缩传输的场景下，本申请实施例中，也可以是终端设备确定多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率值，进而LMF网元根据多个辅助数据以及多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率值，确定多个待测角度。换言之，对于任意一个待测角度，LMF网元可以将对应的辅助数据中包括的一个或多个PRS资源标识在相应预设角度上对应的功率信息还原成其在相应预设角度上对应的功率值，进而与该待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率值进行匹配，从而确定出相应待测角度，本申请实施例对此不作具体限定。

目前，基于现有的辅助数据只能估计出角度(离开角/到达角)的一个大致范围，无法实现高精度定位。基于本申请实施例提供的定位方法，由于本申请实施例中的辅助数据包括与一个或多个预设角度对应的一组或多组映射关系，其中，一组或多组映射关系中的每组映射关系分别与一个或多个预设角度中的一个预设角度对应，每组映射关系均包括一个或多个PRS资源标识中的每个PRS资源标识和每个PRS资源标识在相应预设角度上对应的功率信息的映射关系。因此LMF网元根据多个辅助数据以及多个待测角度中每个待测角度下的一个或多个PRS资源标识在相应待测角度上对应的功率信息，可以进行准确的待测角度估计，进而可以实现高精度定位。
其中，上述步骤S901至S915中的终端设备或NG-RAN设备或LMF网元的动作可以由图8所示的通信装置800中的处理器801调用存储器803中存储的应用程序代码来执行。
