Description

一种定位方法以及装置

技术领域
本申请涉及通信领域，尤其涉及一种定位方法以及装置。
背景技术
目前应用于通信系统的定位技术包括如下几种方式：增强的基于小区身份标识的定位技术(enhanced cell identity，ECID)、辅助的全球导航卫星系统技术(assisted-global navigation satellite system，A-GNSS)以及观察到达时间差技术(observed time difference of arrival，OTDOA)。相对来说，OTDOA技术不需要使用GNSS信号，而是利用类似于GNSS的定位原理，通过测量两个或更多的发送站点(transmission point，发送站点)发送的定位参考信号到达终端设备的时间差，然后在已知各发送站点的位置的情况下计算出终端设备的所在位置。
在OTDOA技术中采用相应的位置估算算法，这种位置估算算法至少需要考虑3个发送站点的位置信息，通常采用求解双曲线方程的解得到终端设备的位置坐标。但由于双曲线的交点并不唯一，因此有可能出现三个发送站点无法定位所述终端设备所处位置的情况，需要增加终端设备测量发送站点的数目，导致估算终端设备所需要的发送站点增多，计算复杂。

具体实施方式
本申请实施例提供了一种定位方法以及装置，用于减少发送站点的数目，从而降低定位的计算复杂度。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、 产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
目前应用于通信系统的定位技术包括如下几种方式：ECID、A-GNSS以及OTDOA。相对来说，OTDOA技术不需要使用GNSS信号，而是利用类似于GNSS的定位原理，通过测量两个或更多的发送站点(transmission point，发送站点)发送的定位参考信号到达终端设备的时间差，然后在已知各发送站点的位置的情况下计算出终端设备的所在位置。如图1所示，该终端通过测量基站A、基站B以及基站C各自的参考信号到达该终端的时间差，从而确定该终端的位置。在OTDOA技术中采用相应的位置估算算法，这种位置估算算法至少需要考虑3个发送站点的位置信息，通常采用求解双曲线方程的解得到终端设备的位置坐标。比如图2所示，在确定该基站A的位置坐标为(x 1，y 1)，该基站B的位置为(x 2，y 2)，该基站C的位置为(x 3，y 3)；对于任一点(x，y)，假设信号从基站A、基站B、基站C传输到此点的时间分别为：那么就可以建立如下两个双曲线方程：
Figure PCTCN2019105040-appb-000001
Figure PCTCN2019105040-appb-000002
然后求解该双曲线方程得到点(x，y)的坐标。但由于双曲线的交点并不唯一，因此有可能出现三个发送站点无法定位该终端设备(即该点(x，y))所处位置的情况，需要增加终端设备测量发送站点的数目，导致估算终端设备所需要的发送站点增多，计算复杂。
为了解决该问题，本申请实施例提供如下方案：终端接收定位实体发送的定位辅助信息，该定位辅助信息包括待测量站点所处小区的小区标识、该待测量发送站点的身份标识以及该待测量发送站点的定位参考信号配置信息；然后该终端解析该定位辅助信息，获取定位参考信号配置信息以及该待测量站点；然后该终端接收到该待测量发送站点发送的定位参考信号，从而获取该定位参考信号信息，得到测量结果，该测量结果包括该定位参考信号信息；最后该终端将该测量结果发送出去。
本申请实施例主要应用于5G新无线接入技术(new RAT(radio access technology)，NR)系统中，也可以应用于其他的通信，只要该通信系统包括可以发送传输方向指示信息的第一实体，以及接收该指示信息的第二实体；且该第二实体可以根据该指示信息确定一段时间内的传输方向即可。例如图3所示，本申请实施例的一个应用场景。在此系统架构中，该基站与用户设备(user equipment，UE)，组成一个通信系统，其中，UE包括UE1至UE6。在该通信系统中，UE1至UE6可以发送上行数据给基站，基站接收该UE1至UE6发送的上行数据。此外，UE4至UE6也可以组成一个通信系统。在该通信系统中，基站可以发送下行数据给UE1、UE2、UE3和UE5；UE5也可以发送下行信息给UE4和UE6。
具体请参阅图4所示，本申请实施例中定位方法的一个实施例如下，包括：
401、服务基站向定位实体发送第二定位辅助信息，该第二定位辅助信息包括发送站点集合中各发送站点所处小区的小区标识、该各发送站点的定位参考信号配置信息、该各发送站点的身份标识以及该各发送站点的定位参考信号信息集合。
本实施例中，一个服务基站会管理多个发送站点，即该服务基站服务于一个发送站点 集合。然后在定位之前，该服务基站需要将该发送站点集合的第二定位辅助信息发送给该定位实体。其中，该第二定位辅助信息包括该发送站点集合中各个发送站点所处小区的小区标识、该各发送站点的定位参考信号配置信息、该各发送站点的身份标识以及该各发送站点的定位参考信号信息集合。
具体来说，该各发送站点的定位参考信号信息集合包括定位参考信号的编号信息，以及定位参考信号的方向信息、定位参考信号的到达角度信息或定位参考信号的地理位置信息中至少一项。其中，该定位参考信号的编号信息、该定位参考信号的方向信息与该定位参考信号的到达角度信息均与该定位参考信号的地理位置信息相关联。具体来说，该定位实体可以该定位参考信号的编号信息、该定位参考信号的方向信息或该定位参考信号的到达角度信息中的至少一项查询到该定位参考信号的地理位置信息。其中，可以以映射表或关联表的方式存储该定位参考信号的编号信息、该定位参考信号的方向信息或该定位参考信号的到达角度信息与该定位参考信号的地理位置信息之间的关联关系，也可以采用其他可用方式，具体此处不做限定。下面以一个示例性实例进行说明，假设发送站点1包括3个定位参考信号，则该发送站点1的定位参考信号信息集合则可以如表1所示：
表1
Figure PCTCN2019105040-appb-000003
可选的，该定位参考信号配置信息包括定位参考信号的周期、频域位置、时域位置或码域位置中的至少一项。
可以理解的是，定位参考信号配置信息中通常定义一个定位参考信号簇的信息，然后在该定位参考信号簇的信息的基础上，描述各个定位参考信号的信息。比如该定位参考信号配置信息中包括一个定位参考信号簇的信息，即包括该定位参考信号簇的周期为10秒，频域位置为信道1，时域位置为时隙2至时隙5，码域位置为第5个符号至第10个符号；然后该定位参考信号簇中包括3个定位参考信号；其中，定位参考信号1位于时隙3，第6个符号；定位参考信号2位于时隙2，第7个符号；定位参考信号3位于时隙4，第5个符号。
可以理解的是，本实施例中为了进行区分，将该服务基站发送给该定位实体的定位辅助信息标记为该第二定位辅助信息；将该定位实体发送给该终端的定位辅助信息标记为第一定位辅助信息。即该第二定位辅助信息相当于权要中服务基站发送给定位实体的定位辅助信息，该第一定位辅助信息相当于权要中定位实体发送给该终端的定位辅助信息。本实施例中，均以第一定位辅助信息和第二定位辅助信息进行说明。本实施例中，该定位参考信号信息可以是波束信息，具体情况此处不做限定。
本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，用于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的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c或者a-b-c，其中，a，b，c可以是单个，也可以是多个。
402、定位实体向终端发送的第一定位辅助信息，该第一定位辅助信息包括待测量发送站点所处小区的小区标识以及该待测量发送站点的定位参考信号配置信息，该待测量发送站点包含于该发送站点集合。
在需要对该终端进行定位时，该定位实体向该终端发送第一定位辅助信息，其中，该第一定位辅助信息包括该待测量发送站点所处小区的小区标识、该待测量发送站点的身份标识以及该待测量发送站点的定位参考信号配置信息。
可选的，该定位实体在发送该第一定位辅助信息给该终端时，可以有如下几种可能方式：
一种可能实现方式中，该定位实体直接触发该第一定位辅助信息的发送动作，即由该定位实体主动发送该第一定位辅助信息给该终端。
一种可能实现方式中，该定位实体在接收到该终端的请求信息之后，再向该终端发送该第一定位辅助信息。
其中，该第一定位辅助信息还包括该待测量发送站点的测量时间信息。
403、该终端向该服务基站发送定位测量请求，该定位测量请求包括测量间隙请求。
该终端在接收到该第一定位辅助信息之后解析该第一定位辅助信息得到该待测量发送站点所处小区的小区标识以及该待测量发送站点的定位参考信号配置信息，在满足触发条件的情况下，该终端向该服务基站发送定位测量请求，该定位测量请求包括测量间隙请求。
本实施例中，该终端向该待服务基站发送该测量间隙请求可以有如下几种可能方式：
一种可能实现方式中，该终端可以主动向该服务基站发送该测量间隙请求。
另一种可能实现方式中，该终端在接收到该定位实体发送的定位请求之后再向该服务基站发送该测量间隙请求。
可以理解的是，上述两种方式可以基于不同的应用场景来使用，比如在该终端需要获取自身的位置信息时，该终端可以直接向该服务基站发送该测量间隙请求；在第三方(比如该定位实体或者另一终端等)需要获取该终端的位置信息时，该终端可以接收到该定位实体发送的定位请求之后再向该服务基站发送该测量间隙请求。
可选的，该测量间隙请求包括测量周期、测量偏置值或测量时间长度中的至少两项。
其中，测量周期用于指示该终端对于定位参考信号的测量周期，该测量偏置值用于指示该终端对于定位参考信号的测量计时开始时刻，该测量时间长度用于指示该终端对定位参考信号的测量时长。比如，该终端上报该定位参考信号1的测量周期为每过5秒测量一次，该测量偏置值为0(即计时以0开始)，测量时间长度为测量15秒(即接收15秒的定位参考信号)。本实施例中，该终端向该服务基站上报每个定位参考信号的测量时间长 度，可以让该服务基站为各定位参考信号配置更合理的测量时长，满足定位测量需求。
可选的，该终端在上报该测量间隙信息时，可以采用如下几种方式：一种可能实现方式中，该终端将该测量间隙信息中的各信息单独上报；一种可能实现方式中，该终端向该服务基站上报间隙模式信息(又可以称为Gap pattern)，然后该间隙模式信息中包括该测量间隙信息中的各信息。一种示例性实例中，在该测量间隙信息包括该测量周期、测量偏置值和该测量时间长度时，该终端将测量周期、测量偏置值以及测量时间长度分别单独上报给该服务基站；或，该终端向该服务基站上报间隙模式信息，该间隙模式信息包括该测量周期、测量偏置值和该测量时间长度。
404、该服务基站向该终端发送测量配置信息。
该服务基站在接收到该终端发送的测量间隙请求之后，根据该测量间隙请求中的基本参数为该终端配置相应的测量配置信息，并发送给该终端。
405、该终端根据该测量配置信息对该待测量发送站点进行测量得到测量结果，该测量结果包括测量到的该待测量发送站点的定位参考信号信息。
该终端接收到该测量配置信息之后，接收该待测量发送站点发送的定位参考信号，并对该定位参考信号进行测量，并获取该定位参考信号信息；然后该终端生成测量结果，其中该测量结果包括该终端测量到的该待测量发送站点的定位参考信号信息。其中，该测量结果还可以包括该待测量发送站点所处小区的小区标识、该待测量发送站点的身份标识。该定位参考信号信息可以包括定位参考信号编号、定位参考信号方向信息或定位参考信号角度信息中的至少一项。
可以理解的是，每一个发送站点可以包括多个定位参考信号，但是终端在接收该发送站点的定位参考信号时，可能只接收到该发送站点的部分定位参考信号，由于该定位实体可以获取该发送站点的全部定位参考信号信息，因此该终端可以只上报测量到的定位参考信号编号。可选的，该终端也可以直接上报测量到的定位参考信号的全部信息。比如，假设发送站点2拥有5个定位参考信号，具体信息分别如下：定位参考信号1的方向为偏北30度、定位参考信号2的方向为偏东20度、定位参考信号3的方向为正东、定位参考信号4的方向为正南以及定位参考信号5为的方向为正西。在该终端对该发送站点2进行定位参考信号测量时，测量到了定位参考信号3，则该终端可以直接向该定位实体上报该定位参考信号3的编号“3”，也可以向该定位实体定位参考信号3的编号以及方向信息。
406、该终端将该测量结果发送给该定位实体。
该终端测量到的测量结果发送给该定位实体。
可以理解的是，本实施例中，该定位实体可以是单独存在的硬件实体也可以是基站的一部分，在该终端发送该测量结果时，该终端可以将该测量结果透传给该定位实体；也可以将该测量结果发送给基站，然后基站接收到该测量结果之后传递给该定位实体。
407、该定位实体根据该测量结果确定该终端的位置信息。
该定位实体在接收到该测量结果之后根据该测量结果确定该终端的位置信息。
本实施例中，该定位实体要获取到该终端的位置信息之后可以将该终端的位置信息反馈给该终端或第三方。
本实施例中，该终端在对该待测量发送站点进行测量时，同时获取承载参考信号的定位参考信号的定位参考信号信息，并上报给定位实体，即对该定位实体定位该终端增加了约束条件，当终端的位置信息不唯一时，该定位实体可以定位参考信号信息确定位置信息，而定位唯一时，可以校验位置信息确保位置信息的准确度。同时，该终端在上报测量间隙请求时，增加了测量时间长度，从而使得发送站点可以为终端配置更合适的Gap参数，满足定位测量需要。

作为本实施例的另一种形式，提供一种计算机可读存储介质，其上存储有指令，该指令被执行时执行上述方法实施例中终端侧的方法。
作为本实施例的另一种形式，提供一种包含指令的计算机程序产品，该指令被执行时执行上述方法实施例中终端侧的方法。
