Description

用于定位的方法与装置
本申请要求于2019年03月28日提交中国国家知识产权局、申请号为201910245452.9、申请名称为“用于定位的方法与装置”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
本申请涉及通信领域，并具体地，涉及一种用于定位的方法与装置。
背景技术
下行离开角(downlink angle of departure，DAOD)定义为网络设备和终端设备之间下行电磁波传输时从网络设备处观测的电磁波离开方向。在视距通信下(line of sight，LOS)，DAOD对应了网络设备与终端设备的地理相对位置的方向信息，因此，可以基于DAOD实现终端设备的定位。例如，基于至少两个网络设备分别与终端设备之间的DAOD，实现该终端设备的定位。
对于DAOD的测量，可以通过如下流程实现：网络设备(例如基站)向终端设备发送多个不同波束方向的参考信号；终端设备接收并测量多个参考信号的接收功率；利用测量的不同波束方向的参考信号的接收功率之间的比例关系，以及每个发送信号对应的波束方向，可以确定网络设备与终端设备之间的DAOD。
目前，尚无适用于DAOD定位的参考信号配置以及测量上报配置的方案。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。
图1为下行离开角(DAOD)的示意图。如图1所示，DAOD表示网络设备与终端设备之间下行电磁波传输时从网络设备处观测的电磁波离开方向。
前文已述，可以基于至少两个网络设备分别与终端设备之间的DAOD，实现该终端设备的定位。这至少两个网络设备可以包括终端设备的服务基站(也可称为服务小区)，和/或邻区基站(也可称为邻小区)。
实现DAOD定位的前提是，先测量得到DAOD。
作为示例，图2为测量DAOD的示意图。如图2所示，网络设备预置3个波束(图2中所示的波束1、波束2和波束3)，预先测得每个波束在不同出射角度上的增益，网络设备利用这3个波束向终端设备发送参考信号。当终端设备位于某个方向时，例如图2中 所示的30度时，测量3个波束上的参考信号接收功率(reference signal received power，RSRP)进行测量。
其中，波束1由于没有对准终端设备，测得的接收功率较低；波束2相对于波束1稍微对准了一点终端设备，测得的接收功率中等；波束3相对对准终端设备，测得的接收功率较高。
终端设备将测量结果反馈给网络设备后，网络设备将测量结果与预先测得的每个波束在不同出射角度上的增益进行匹配，发现与30度方向上三个波束之间的增益更匹配，从而确定终端设备在30度方向上，即确定DAOD为30度。
从图2可知，在测量DAOD之前，需要先为终端设备配置参考信号配置信息与测量上报配置信息。
目前，有两种可用于为终端设备配置参考信号配置信息与测量上报配置信息的配置框架：1)服务小区CSI获取/波束管理框架(TS 38.331中的CSI-MeasConfig信元)；2)服务小区移动性管理框架(TS 38.331中的MeasObjectNR)。
其中，框架1主要适用于参与定位的小区均为服务小区(载波聚合)，当参与定位的小区包括邻时，不支持异频测量，也不支持邻区的SSB测量。框架2的上报机制不适合DAOD。
上述可知，需要提出一种适用于DAOD定位的参考信号配置与测量上报配置的方案。
据此，本申请提出一种用于定位的方法与装置，可以较好地实现用于DAOD定位的参考信号配置与测量上报配置。
本申请实施例可以应用于5G系统或新无线(new radio，NR)系统。
图3为本申请实施例可以应用的通信架构的示意图。该通信架构中包括终端设备(图3中表示为UE)、无线接入网(NG-RAN)和核心网。

图3中的ng-eNB也可以替换为传输节点(transmission point，TP)(如图3中所示的 TP)。
图4为本申请实施例可以应用的另一通信架构的示意图。该通信架构包括终端设备(图4中表示为UE)、无线接入网(NG-RAN)和核心网。
核心网包括AMF与LMF等功能。AMF实现网关等功能，LMF实现定位中心等功能，AMF与LMF之间通过NLs接口连接。
无线接入网(NG-RAN)包括一个或多个ng-eNB和gNB。ng-eNB表示接入5G核心网的LTE基站，gNB表示接入5G核心网的5G基站。
其中，gNB包含定位管理组件(location management component，LMC)，LMC可以承担了一部分LMF的功能。这样，如果要实现LMC可以承担的这部分LMF功能，不需要无线接入网经由AMF引入5G核心网，从而可以降低信令时延。
应理解，该通信架构中可以包括一个或多个基站(包括ng-eNB与gNB)。
还应理解，该通信架构中可以包括一个或多个终端设备，例如包括一个或多个终端设备组(如图4中所示的UE set)

本申请实施例中涉及的网络设备可以用于与一个或多个终端进行通信，也可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站，如接入点，之间的通信)。基站可以是LTE系统中的演进型基站(evolved Node B，eNB)，或者5G系统、NR系统中的基站(gNB)。另外，基站也可以为接入点(access point，AP)、传输节点(transport point，TRP)、中心单元(central unit，CU)或其它网络实体，并且可以包括以上网络实体的功能中的一些或所有功能。例如，本申请实施例中涉及的网络设备可以对应于图3和图4所示通信架构中的接入网设备。
本申请实施例中涉及的定位管理设备表示具有定位管理功能的核心网设备，例如，图3中所示的LMF，或者，定位管理设备表示具有定位管理功能的可置于接入网设备中的装置，例如，图4中所示的LMC。
本申请提出基于LTE定位协议(LPP)实现用于DAOD定位的参考信号配置与测量上报配置。根据本申请实施例的用于定位的方法包括：定位管理设备通过LPP，向终端设备提供一个或多个小区的参考信号配置信息与测量上报配置信息，通过LPP从终端设备接收该终端设备对该一个或多个小区测量所得的参考信号测量结果，根据该参考信号测量结果获取该终端设备分别相对于该一个或多个小区的DAOD。下文将结合图5进行详细说明。

再例如，当终端设备支持径功率，则测量上报配置信息包括指示需要上报径功率的信息，或者，还可以包括每根径上报的功率的个数。
定位管理设备可以根据在步骤S520中获取的终端设备的能力信息获知终端设备是否支持径功率上报。
可选地，步骤S550的一种实现方式为：定位管理设备向终端设备发送携带测量上报 配置的请求消息。
S560，终端设备测量定位小区的参考信号，获得定位小区的参考信号测量结果。
终端设备根据在步骤S540中从定位管理设备接收的小区的信息，确定定位小区，即确定要接收哪些小区的参考信号。
根据在步骤S540中从定位管理设备接收的参考信号配置信息，终端设备从对应定位小区接收参考信号。应理解，相应定位小区也从定位管理设备接收到了对应的参考信号配置信息，换言之，终端设备与一个定位小区是基于相同或相近的参考信号配置信息进行参考信号传输。
根据在步骤S550中从定位管理设备接收的测量上报配置信息，终端设备对接收到的参考信号进行测量，获得定位小区的参考信号测量结果。
若测量上报配置信息中指示不需要上报径功率，终端设备对定位小区的参考信号进行RSRP测量，并按照测量上报配置信息中指示的上报的RSRP的个数确定要上报的RSRP的个数。例如，终端设备测量定位小区的PRS资源集合和/或SSB资源集合的RSRP，RSRP个数按照测量上报配置信息的配置确定。
若测量上报配置信息中指示需要上报径功率，终端设备对定位小区的参考信号进行径功率测量，并按照测量上报配置信息中指示的每根径上报的功率的个数确定每根径上上报的功率数。再例如，终端设备测量定位小区的PRS资源集合和/或SSB资源集合的径功率，每根径的功率数数按照测量上报配置信息的配置确定。
如果测量上报配置信息指示的上报配置为非径功率上报，需要要求终端设备采用同一接收波束(记为接收波束A)接收一个小区的多个下行波束。这个接收波束A应当最大化这多个下行波束中最大那个波束的RSRP。
例如，针对一个小区，网络侧有M个下行波束，终端侧有N个接收波束，终端设备总共可以获得M*N个RSRP。此时，终端设备采用的接收波束应当为M*N中RSRP中最大的那个RSRP对应的接收波束。
如果测量上报配置信息指示的上报配置为径功率上报，网络侧会配置一个或多个基准参考信号。对于每个基准参考信号，终端设备选择一个接收波束最大化该基准参考信号的RSRP，并且用该接收波束接收其他发送波束。依次重复其他基准参考信号。
例如，针对一个小区，有M个下行波束，M个下行波束中有O个基准参考信号(剩余M-O个波束不通过基准参考信号发送)，终端侧有N个接收波束。针对每个基准参考信号，终端设备选择一个接收波束，最大化该基准参考信号的RSRP，并用该接收波束接收M个下行波束，选择一根径，获得M个径功率。遍历O个基准参考信号，选择O个接收波束，总共获得M*O个径功率。此时对于一个发送波束，有可能是采用多个接收波束接收的。
S570，终端设备向定位管理设备发送步骤S560测得的参考信号测量结果。
终端设备向定位管理设备发送每个定位小区的参考信号测量结果。
可选地，步骤S570的一种实现方式为：终端设备向定位管理设备发送携带参考信号测量结果的响应消息。
S580，定位管理设备根据参考信号测量结果，获取DAOD。
可选地，定位管理设备可以将参考信号测量结果发送给相应的定位小区，由各定位小 区的基站基于参考信号测量结果计算出DAOD并反馈给定位管理设备。
可选地，定位管理设备预先收集各个定位小区的波束信息，基于参考信号测量结果计算获得对应于各个定位小区的DAOD。
若在步骤S570中，终端设备上报了RSRP，即参考信号测量结果包括RSRP，一个定位小区对应一个DAOD。
若在步骤S570中，终端设备上报了径功率，即参考信号测量结果包括径功率，一个定位小区可以对应多个DAOD，其中，每一根径对应一个DAOD。
可选地，在一些实施例中，可以不执行步骤S510，相应地，在步骤S520中，终端设备自发地向定位管理设备上报终端设备的能力信息。
可选地，在一些实施例中，可以不执行步骤S510和步骤S520。
作为一种可能的实现方式，终端设备不向定位管理设备发送能力信息，相应地，在步骤S540中，定位管理设备不会参考终端设备的能力信息确定参考信号配置信息；在步骤S550中，定位管理设备不会参考终端设备的能力信息确定测量上报配置信息。
作为另一种可能的实现方式，定位管理设备接收一次终端设备上报的能力信息后，在后续多次为终端设备配置参考信号配置信息与测量上报配置信息的过程都可以参考终端设备之前上报的能力信息。即无需终端设备在每次配置过程中都上报自己的能力信息。
可选地，在一些实施例中，可以不执行步骤S530。相应地，在步骤S540中，定位管理设备无需依赖终端设备的请求而向终端设备提供辅助信息，换言之，步骤S540可以解耦于步骤S530而存在。例如，定位管理设备在接收到终端设备的服务小区发送的定位请求后，向终端设备提供辅助信息。
在本实施例中，在步骤S540中，定位管理设备可以根据历史数据大致估计终端设备的位置，进而确定参与终端设备定位的一个或多个小区(即定位小区)。
在本实施例中，在步骤S540中，定位管理设备可以根据从定位小区获取的参考信号配置信息，确定为终端设备下发的参考信号配置信息。
在本申请中，由定位管理设备与终端设备进行交互，来实现用于DAOD定位的参考信号配置与上报测量配置。因此，本申请对用于终端设备定位的小区没有同频的限制，即可以支持异频定位。此外，针对用于终端设备定位的小区为邻小区时，现有的配置框架，针对邻小区，参考信号不能是SSB，而本申请对此没有限制。
此外，现有的配置框架中，对终端设备一次上报的RSRP的个数有限制。而在本申请中，对终端设备上报的RSRP的个数没有限制。而且，本申请提供的配置方式还支持径功率的上报。
再有，在本申请的一些实施例中，支持终端设备上报能力信息，这些信息有利于定位管理设备为终端设备确定较为合理的参考信号配置信息与测量上报配置信息。
再有，在本申请的一些实施例中，支持终端设备上报该终端设备对至少一个小区的历史下行参考信号的测量结果，这些信息也有利于定位管理设备为终端设备确定较为合理的参考信号配置信息与测量上报配置信息。
因此，相对于现有技术，本申请提出一种较为适合DAOD定位的配置参考信号配置信息与测量上报配置信息的方案。
作为示例而非限定，下面给出步骤S510至步骤580的具体实现方式。
步骤S510包括：定位管理设备向终端设备发送能力请求消息(RequestCapability消息)，RequestCapability消息中携带DAOD能力请求信元(DAOD-RequestCapability IE)，DAOD-RequestCapability IE指示终端设备需要提供的能力信息。

可以理解到，本申请可以基于现有的LTE定位协议(LPP)实现用于DAOD定位的配置，从而既可以兼容现有协议，又可以在增加较少信令开销的基础上实现用于DAOD定位的配置。
如图1所示，如果是从终端设备向网络设备传输电磁波，则从网络设备处观测电磁波到达方向，也会形成一个到达角，这个到达角可以称为上行到达角(Uplink angle of arrival， UAOA)。从UAOA的定义出发，UAOA应该是基于上行信号测量得到。
从图1可以看出，UAOA与DAOD虽然定义不同，获取方式也不同，但是本质上是同一个物理量，即终端设备相对于网络设备的方向角。这个方向角可以统称为到达角(Angle of arrival，AoA)。
也就是说，如果获得DAOD，其实也相当于获得了UAOA。通过本申请提供的技术方案获得DAOD，同时也就获得的了UAOA。因此，本申请提供的技术方案既可以用于确定DAOD，也可以用于确定UAOA。可以认为，本申请提供的技术方案可以用于确定AoA。
在上文任一实施例中，作为可选的实施方式，可以将“DAOD”替换为“AoA”，该“AoA”可以表示DAOD，也可以表示UAOA。
此外，还需要说明的是，到达角(AOA)包含了垂直方向角(Zenith angle of arrival，ZOA)和水平方向角(Azimuth angle of arrival，AOA)两个维度。
如图6所示，垂直方向角表示终端设备相对于网络设备的方向与穹顶方向之间的夹角θ，水平方向角表示终端设备相对于网络设备的方向在水平面内相对于正北方向的夹角

结合图6描述的夹角。图6中所示的夹角，以逆时针为正，顺时针为负。
针对DAOD，垂直方向角表示网络设备与终端设备之间下行电磁波传输时从网络设备处观测的电磁波离开方向与穹顶方向之间的夹角θ，水平方向角表示网络设备与终端设备之间下行电磁波传输时从网络设备处观测的电磁波离开方向在水平面内相对于正北方向的夹角
