Description

信息处理方法、通信设备、系统及存储介质
本申请要求于2018年09月27日提交中国专利局、申请号为201811133698.9、申请名称为“信息处理方法、通信设备及存储介质”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，特别涉及信息处理方法、通信设备、系统及存储介质。
背景技术
基站对终端进行定位一般是通过观察达到时间差(Observed Time Difference Of Arrival，UTDOA)定位方法实现的，该方法以多个位置测量单元(Location Measurement Unit，LMU)测量终端发送的定位信号的到达时刻，并将达到时刻发送给定位实体，从而，定位实体根据这些到达时刻的时间差，实现对终端的定位。
目前，利用UTDOA方法对终端进行定位一般应用于长期演进(Long Term Evolution，LTE)技术。而在LTE中，终端发送定位信号时是全向发送的。也就是说，位于终端所处位置附近的LMU都可以接收到终端发送的定位信号，换言之，这些接收到定位信号的LMU都可以将接收到定位信号的接收时刻发送给定位实体，定位实体则基于各LMU上报的接收时刻确定定位信号的到达时间差，并根据到达时间差实现对终端的定位。
但是，由于新无线接入技术(New RAT(Radio Access Technology)，NR)工作在较高的频谱，为了对抗衰落，NR基站的信号是基于波束赋形实现发射的，并且，每个波束会对应一个方向，这就导致某些LMU无法接收到终端发送的定位信号，从而，定位实体也就无法基于定位信号的到达时间差完成对终端的定位。
发明内容
本申请提供了一种信息处理方法、通信设备、系统及存储介质，以期在NR系统中实现终端定位。
第一方面，本申请提供了一种通信方法，该方法包括：网络设备生成上行参考信号的第一配置信息，所述第一配置信息包括：上行参考信号资源与第一信息的第一映射关系，所述第一信息是位置测量单元LMU的下行参考信号的信息，所述LMU是除服务基站之外的其他LMU；所述网络设备发送所述第一配置信息至终端。通过本实施例提供的方案，通过第一配置信息的指示，终端能够在配置好的上行参考信号资源上发送定位信号，从而，与之对应的第一信息对应的LMU可以接收到该定位信号，从而，实现NR系统的UTDOA定位。
在一种可能的设计中，所述方法还包括：所述网络设备发送第二配置信息至定位实体，所述第二配置信息包括：所述上行参考信号资源与所述LMU的第二映射关系。通过本实 施例提供的方案，为定位实体自由挑选目标LMU提供了可能，定位实体能够挑选到更符合自身定位需求的LMU作为目标LMU，有利于提高定位精度。
在一种可能的设计中，所述第一信息为所述终端测量到的LMU的下行参考信号的编号信息或者索引信息。一方面，终端测量得到的LMU保证了终端能够发送定位信号至这些LMU，而这些LMU也能够接收到终端发送的定位信号，从根本上保证了定位测量的基础；另一方面，第一信息为这些LMU的下行参考信号的编号信息或者索引信息，这能够唯一标记一个波束方向，而编号信息或者索引信息的信息量较小，有利于第一映射关系的建立以及数据的传输。
在一种可能的设计中，所述方法还包括：所述网络设备接收定位实体发送的针对所述终端的定位请求信息。也就是，网络设备在接收到定位实体发出的定位请求信息后才开始执行前述方案，节省系统资源。

在一种可能的设计中，所述LMU为所述终端测量到的全部LMU中的部分LMU，所述LMU的信号强度大于或者等于预设的信号强度阈值。通过本实施例提供的方案，通过终端对测量到的LMU进行信号强度的筛选，仅将其中信号强度较高的部分LMU的作为可用于定位测量的LMU，以尽量避免在定位测量过程中由于信号强度影响接收时刻的情况。
在一种可能的设计中，所述方法还包括：所述网络设备判断所述LMU的数目是否大 于或者等于定位测量所需LMU的最小数目；若所述LMU的数目小于所述最小数目，所述网络设备发送通知消息至定位实体，所述通知消息用于通知所述定位实体所述终端当前所处位置不满足定位条件。通过本实施例提供的方案，能够保证网络设备配置并发送给终端的第一配置信息能够满足UTDOA定位测量的最低要求，避免了由于LMU的数目不够而导致定位实体进行终端定位时的接收时刻的数目不足进而导致无法定位的情况。
在一种可能的设计中，所述第二配置信息还包括所述第一映射关系。此时，定位实体可还可进一步确定各上行参考信号资源对应的波束方向，在一定程度上能够避免目标LMU处定位信号接收错误的情况。
在一种可能的设计中，所述第一配置信息还包括所述上行参考信号资源与所述LMU之间的第二映射关系。此时，终端可根据第一配置信息确定自身发送的定位信号的接收方与波束方向，更有针对性，在一定程度上能够避免信号传递错误的情况。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
本申请实施例可应用于5G NR系统。此外，本申请还可应用于其他需要进行传输方向指示的任意通信系统，在这些通信系统中，存在用于发送传输方向第一信息的实体，以及， 存在另一实体可接收该第一信息，并根据该第一信息确定一定时间内的信号传输方向。
图1为本申请实施例提供的一种应用场景示意图。该通信系统包括：网络设备与多个终端，其中，图1中示出了6个终端(终端1～终端6)。在图1所示的通信系统中，终端1～终端6均可以发送上行数据至网络设备，网络设备可接收终端1～终端6发送的上行数据，并向终端1～终端6发送下行数据。此外，如图1所示，终端4～终端6也可以组成一个通信系统，在由终端4～终端6所组成的通信系统中，网络设备可发送下行数据给终端5，而终端5可接收终端4与终端6发送的上行数据，并向终端4与终端6发送下行数据。
其中，网络设备可以是网络侧设备，例如，无线保真(Wireless-Fidelity，WIFI)的接入点AP、下一代通信的基站，如5G NR基站，如：5G gNB或小站、微站，传输接收点(Transmission Reception Point，TRP)，还可以是中继站、接入点、车载设备、可穿戴设备等。在本实施例中，不同通信制式的通信系统中的基站不同。为了区别起见，将4G通信系统的基站称为LTE eNB，5G通信系统的基站称为NR gNB，既支持4G通信系统又支持5G通信系统的基站称为eLTE eNB,这些名称仅为了方便区别，并不具有限制意义。
终端又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
此外，定位实体，可以为定位服务器。本申请中，定位实体可以包括但不限于；演进的服务移动位置中心(Evolved Serving Mobile Location Center，E-SMLC)或者位置管理功能(Location Management Function，LMF)。
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”，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a-b-c，其中a,b,c可以是单个，也可以是多个。
需要说明的是，图1所示的通信系统中所包含的终端的数量和类型仅仅是一种举例，本申请实施例并不限制于此。例如，还可以包括更多的与网络设备进行通信的终端，为简明描述，不在附图中一一描述。此外，在如图1所示的通信系统中，尽管示出了网络设备和终端，但是该通信系统可以并不限于包括网络设备和终端，例如还可以包括核心网节点或用于承载虚拟化网络功能的设备等，这些对于本领域技术人员而言是显而易见的，在此不一一赘述。
另外，本申请实施例不仅可应用于下一代无线通信系统,即5G通信系统，还可应用于未来可能出现的其他需要进行传输方向指示的通信系统,例如下一代的wifi网络、5G车联网等。
需要说明的是，随着通信系统的不断演进，未来可能出现的其他系统中，上述各个网元的名称可能会发生变化，在这种情况下，本申请实施例提供的方案同样适用。
为了便于说明，以下对UTDOA技术进行简单说明。
UTDOA定位方法是由LMU侧测量终端发出的定位信号的接收时刻，并将这些接收时刻发给定位实体，由定位实体根据多个(一般为至少三个)LMU发送的接收时刻之间的到达时间差，来实现对终端的定位。
需要说明的是，LMU为LTE中对进行上行参考信号进行测量的功能站点的名称，在NR系统或者其他系统中可能有其他的名称，例如，在NR系统中称为传输测量功能网元(transmission measurement function，TMF)、传输接收点(transmission reception point，TRP)等，本申请不对LMU具有的其他名称进行限定，只要是具有测量终端设备上行参考信号的功能实体、网元、站点、设备，均可以称为LMU。
可以理解的是，上行参考信号可以具有多种用途，例如，信道测量、定位等功能，在本实施例中主要以上行参考信号用于定位进行说明。
此外，在一些实现场景中，LMU设置于网络设备侧，因此，也可以认为是由网络设备测量终端发出的定位信号的接收时刻，并发送给定位实体的。在这种实现场景中，LMU可以与基站收发台(Base Transceiver Station，BTS)结合在一起，或者，也可以分开设置。以这种是现场场景为例，由于每个BTS的地理位置是已知的，因此可以利用球面三角算出移动终端的位置。图2示出了该场景下UTDOA技术的数学原理。
如图2所示，假设A、B、C点的坐标分别是(x 1,y 1)(x 2,y 2)(x 3,y 3),对于任意点(x，y)，假设信号从此点传输到A、B、C的时间分别为t 1,t 2,t 3,那么就可以建立如下两个双曲线方程：
Figure PCTCN2019107323-appb-000001
Figure PCTCN2019107323-appb-000002
由此，只需要对这两个双曲线方程进行求解，就可以得到任意点(x，y)的坐标，实现对该任意点的定位。
可知，UTDOA测量的是终端发射的定位信号到达不同BTS的传输时间差，而不是单纯的传输时间。此外，在LTE系统中，前述定位信号可以为信道探测参考信号(Sounding Reference Signal，SRS)。
除此之外，在第三代合作伙伴项目长期演进(Third Generation Partnership Project Long Term Evolution，3GPP-LTE)系统中还定义了一种LTE定位协议：轻量级表示协议(Lightweight Presentation Protocol，LPP)。
LPP定位协议作为通用定位通信协议，主要功能在于在网络设备与终端之间交互定位辅助数据和定位信息。实际上它既可以在控制平面也可以在数据平面使用。相对来说，控制平面的实现方式需要用到专用控制信道并且会显着地增加移动网络成本，因为多个网元需要在软件和硬件上升级，才能支持这些定位相关的控制平面信令。因此，用户平面的实现方式更容易被用于商业应用
此外，在一些LTE通信系统中，LPP定位协议已经支持基于卫星定位技术，基于到达时间差定位法(Observed Time Difference of Arrival，OTDOA)定位技术，基于增强的基于小区ID(Enhanced Cell identity，E-CID)定位技术，基于UTDOA的定位技术，基于WIFI的定位技术，基于传感器的定位技术，基于蓝牙的定位技术，基于TBS的定位技术，以及他们的混合定位技术。
在NR系统中，基站的信号是基于波束赋形发射的，根据发射的信号的类别不同，波束的宽度和标号也不同，例如基站发送SSB信号，根据基站工作频率的不同，可以最多有4,8,64个波束，每个波束会对应一个方向。图3示出了NR系统中基站的信号发射方式。如图3所示，同一NR基站基于波束1向终端1发射信号，基于波束2向终端2发射信号，基于波束3向终端3发射信号，而波束1、波束2、波束3分别对应于不同的方向。
同理，在NR系统中，为了提高上行信号的传输效率，上行信号的发送也可以采用波束的形式。如图4所示，终端设备采用波束方式向网络设备发送上行信号。
此外，图5示出了LTE系统的UTDOA定位技术示意图。如图5所示，在LTE系统中，包括如下步骤：
S501，定位实体发送定位请求消息至终端的服务基站(Information Request)。
S502，服务基站决定给终端配置的信道探测参考信号(Sounding Reference Signal，SRS)资源。
S503，服务基站发送携带有该SRS资源配置信息的反馈消息(Information Response)给定位实体。
S504，服务基站将决定好的SRS资源配置给终端。
S505，定位实体将测量配置信息发送给LMU，测量配置信息包括SRS资源配置信息。
S506，LMU将测量到的终端发送的SRS信号的接收时刻发送给定位实体。
如此，终端可根据服务基站配置好的SRS资源发送SRS信号，由于LTE系统中信号是全向发送的，因此，终端周围的LMU则可以接收到终端发送的SRS信号，并记录接收时刻；从而，各LMU将测量得到的接收时刻发送给定位实体。为便于说明，图5仅示出一个LMU。
S507，定位实体根据LMU发送的接收时刻定位终端位置。
由此可知，如图5所示的定位流程并不适用于NR系统，这是由于NR系统工作的频谱较高，为对抗衰落，则NR系统中的信号是以波束的形式发送的，这就会导致某些LMU无法收到UE发送的SRS信号，而无法进行UTDOA定位。
针对前述问题，本申请实施例提供一种可行的解决思路：在NR系统中实现UTDOA定位时，网络设备可首先获取终端附近的LMU的波束信息，从而，为终端配置相应的上行参考信号资源，使得终端可在网络设备配置的上行参考信号资源上进行定位信号发送，如此，LMU也可以接收到终端发送的定位信号。
本申请提供一种信息处理方法，下面结合实施例对该信息处理方法进行详细的描述。
图6示出了本申请提供的一种信息处理方法的交互流程示意图。如图6所示，该方法可以包括如下步骤：
S602，定位实体发送针对终端的定位请求信息至网络设备。
其中，定位请求信息中携带需要进行定位的终端的信息。此外，在一个可能的实现场景中，该定位请求信息中还可以携带定位实体自身选择的部分候选LMU的标识信息。
其中，本申请所涉及到的LMU的标识信息可以包括但不限于如下至少一种：物理小区标识(Physical Cell Identifier，PCI)；小区全局标识符(E-UTRAN Cell Global Identifier，ECGI)；频点；是否支持上行辅助频段(supplement UpLink，SUL)；下行参考信号的序 列编号。这些LMU的标识信息能够对LMU进行标识，在具体实现时，仅通过这些LMU的标识也可能唯一确定一个LMU。
还需要说明的是，如图6所示的实现流程为一种可能的实现方式，S604步骤可在接收到定位实体发送的定位请求后执行，也就是，S604步骤可在S602步骤后执行。但是，本申请对S604步骤的触发条件无限定，图6所示的在接收到定位请求信息后的触发仅为一种可能的实现方式，在其他可能的实现场景中，S604可将其他预设条件触发，例如，指令触发等。
S604，网络设备生成上行参考信号的第一配置信息，第一配置信息包括：上行参考信号资源与第一信息的第一映射关系，第一信息是位置测量单元LMU的下行参考信号的信息，LMU是除服务基站之外的其他LMU。
其中，上行参考信号资源主要是时频资源、方向及关联的基站。下行参考信号可以为同步信号和PBCH块(synchronization signal and PBCH block，简称为SSB)，信道状态信息参考信号(channel state information-reference signal，CSI-RS)，定位参考信号(positioning reference signal，PRS)，其中，PBCH为物理广播信道(physical broadcast channel)。
可以理解的是，本申请实施例并不对下行参考信号的具体种类进行限定，其可以根据实际情况选择。
S606，网络设备发送第一配置信息至终端。
S608，终端接收网络设备发送的第一配置信息。
S610，终端根据第一配置信息发送上行参考信号。
具体的，终端可根据第一配置信息中的各第一映射关系，在任意一个第一映射关系所包含的上行参考信号资源、以及与之对应的第一信息所指示的波束方向上发送上行参考信号。
优选的，上行参考信号可以为SRS信号，此时，上行参考信号资源为SRS资源。
S612，目标LMU根据上行参考信号资源，接收上行参考信号，并记录接收时刻。
需要说明的是，图6所示流程中仅示出了目标LMU在该定位测量中的必要步骤，针对其余LMU的流程，本申请无特别限定。此外，图6中仅示出了一个目标LMU，这是由于目标LMU的实现步骤相同，这并不用以限制本申请中目标LMU的数目。
S614，目标LMU将接收时刻发送给定位实体。
S616，定位实体根据接收时刻定位终端位置。
以下，对S604中第一资源配置信息中所包含的第一映射关系进行具体说明。
本申请中，第一映射关系中的上行参考信号资源是网络设备为终端配置的。在执行该步骤之前，网络设备还需要决定(determine)终端的上行参考信号资源。而第一信息为LMU的下行参考信号的信息，由于NR系统中信号是基于波束形式发送的，因此，终端可接收到的LMU的下行参考信号必然对应于一个或多个波束方向，也就是说，该第一信息能够用以指示终端可以接收到的LMU波束的波束方向。由此，终端接收到该第一配置信息之后，可在第一配置信息中指示的上行参考信号资源上发送上行参考信号(以下简称：定位信号)。而基于第一映射关系，终端可以在该上行参考信号资源、第一信息所指示的波束方向上发送定位信号，定位信号就能够被该波束方向上的LMU接收到，从而，能够实现基于UTDOA的定位。
在一个优选的实现场景中，第一信息可以为终端能够测量到的LMU的下行参考信号的编号信息或者索引信息。例如，该第一信息可以为LMU1的波束编号或波束索引。此时，终端能够测量得到某一LMU的下行参考信号，也就说明该LMU的下行参考信号对应的某一个或多个波束方向上发送的数据能够被终端接收到，终端可以确定该波束方向的编号或者索引，如此，当终端需要发送定位信号时，终端只需在该波束编号成对对应的一个或多个波束方向上发送数据，就能够被该LMU接收到。
基于此，网络设备在执行第一配置信息的生成之前，还可以包括如下步骤：获取其中的第一信息。其中，获取第一信息的实质，为获取可用于进行定位测量的LMU的信息。
本申请具体给出以下几种网络设备获取第一信息的方式：
第一种，第一信息由终端测量得到，并且，在终端进行测量之前，定位实体已经选定了部分LMU的情况，此时，网络设备在执行S604之前接收到的定位实体发送的LMU的标识信息。例如，定位实体发送至网络设备的定位请求信息中可以携带LMU的标识信息。
需要说明的是，定位实体在执行S604之前发送给网络设备的LMU的标识信息的LMU(以下，简称候选LMU)可能与最终执行接收时刻上报的LMU(以下，简称目标LMU)不同。这是由于，定位实体是对于终端的位置并不确定，其发送给网络设备的候选LMU可能存在无法接收到终端的定位信号的问题，因此，二者可能会不同。
此外，定位实体可根据终端当前的服务基站的位置，来确定这些候选LMU。也就是，定位实体根据终端的地理位置，确定对终端进行定位测量的各候选LMU，然后，定位实体将定位请求信息发送至网络设备，定位请求信息携带LMU的标识信息。
例如，该网络设备即为终端当前的服务基站，则定位实体需要对终端进行定位时，可在该服务基站周边的预设范围内搜索LMU，并将该预设范围内搜索到的LMU作为候选LMU，将这些候选LMU的标识发送给该服务基站。
图7所示信息处理方法示出了一种第一信息的获取方式。如图7所示，定位实体发送的定位请求信息中携带各候选LMU的标识信息，此时，在执行S604之前，该方法还包括如下步骤：
S60312，网络设备发送第一测量信息至终端，第一测量信息用于指示终端按照各候选LMU的标识信息进行测量，以获得第一信息。
S60314，终端接收第一测量信息，并按照LMU的标识信息进行测量，得到第一信息。
S60316，终端发送第一信息至网络设备。
S60318，网络设备接收终端发送的第一信息。
其中，终端进行LMU测量时，可通过向LMU发送测量信号并接收测量反馈信号的方式实现，若能够接收到LMU发送的测量反馈信号，则将该LMU发送测量反馈信号所在的波束编码信息或波束索引信息作为第一信息；反之，若不能接收到LMU的测量反馈信号，则自身无法测量到该LMU，则无法获取到该LMU的波束方向信息。
也就是说，第一信息是终端在定位实体确定的各候选LMU中进行测量，并将这些候选LMU中自身能够测量到的全部或部分LMU的信息作为第一信息，并发送给网络设备。而第一信息与上行参考信号资源之间的第一映射关系正是为了指导终端如何发送定位信号的。可知，若终端能够在第一信息所指示的波束方向上接收到LMU发送的测量反馈信号，则进行定位测量时，终端在该波束方向成对对应的方向上发送定位信号也能够被前述 LMU接收到。这使得网络设备配置的第一配置信息能够满足终端与LMU的通信要求，也就是，使得终端能够发送定位信号至这些LMU，而这些LMU也能够接收到终端发送的定位信号。
而且，这种实现方式对终端进行LMU测量的范围进行了限定，终端仅需在定位实体所指示的候选LMU中进行测量即可，相对于无范围限制的LMU测量方式，这缩小了终端进行LMU测量的工作量，有利于提高处理效率。
此外，在一种极端的实现场景中，可能存在如下情况：终端按照LMU的标识信息进行LMU测量时，无法测量到任意候选LMU。也就是，定位实体指示的候选LMU均无法接收到终端发送的测量信号，此时，再采用以下第二种或第三种进行第一信息的获取。
第二种，第一信息由终端测量得到，而定位实体未指示候选LMU的标识信息。
图8所示信息处理方法示出了另一种第一信息的获取方式。如图8所示，在执行S604之前，该方法还包括如下步骤：
S60322，网络设备发送第二测量信息至终端，第二测量信息用于指示终端对自身所能测量到的全部LMU进行LMU测量以获得第一信息。
S60324，终端接收第二测量信息，并对自身所能测量到的全部LMU进行测量，得到第一信息。
也即，终端接收到第二测量信息后，在所有潜在的LMU的下行参考信号所在的频点上进行测量，得到第一信息。
S60326，终端发送第一信息至网络设备。
S60328，网络设备接收终端发送的第一信息。
也就是说，网络设备生成的第一配置信息是根据终端所能测量到的全部LMU。这种实现方式对于终端来说，避免了在预设范围内测量无法测量到可用于进行定位的LMU的情况，终端仅需进行一次LMU测量，就能够得到自身能测量到的全部LMU。此外，这种方式有利于扩大第一信息所对应的LMU的数目，而用于进行定位的LMU的数目越多，越有利于提高定位精度。
除此之外，图8所示方式能够作为图7所示方式的补充方式。也就是，若终端接收到第一测量信息，并根据第一测量信息中的LMU的标识信息进行LMU测量，但是无法测量到任何LMU时，一种方式是：终端可向网络设备反馈LMU测量情况，并根据网络设备发送的第二测量信息，执行如图8所示测量流程，并完成第一信息的上报；另一种方式是：终端可自行进行前述S60324中的测量步骤，并向网络设备发送第一信息，这种实现方式中，还可进一步对第一信息进行说明，以通知网络设备这些第一信息是对自身所能测量到的全部LMU进行LMU测量得到的。
前述第一种方式与第二种方式在实际实现时，均以终端实际能够测量到的LMU的信息为第一信息，这保证了网络设备配置的第一配置信息能够满足终端与LMU的通信要求，也就是，使得终端能够发送定位信号至这些LMU，而这些LMU也能够接收到终端发送的定位信号。
以及，本申请还进一步提供了这两种实现方式的一种更优选的实现方式：终端在进行LMU测量(可按照LMU的标识信息进行LMU测量，或者，在自身所能测量到的全部LMU范围内进行LMU测量)后，对测量到的全部LMU中选择部分LMU的信息作为第一信息， 其中，第一信息所对应的部分LMU的信号其强度大于或者等于预设的信号强度阈值。通过终端对测量到的LMU进行信号强度的筛选，仅将其中信号强度较高的部分LMU的作为可用于定位测量的LMU，以尽量避免在定位测量过程中由于信号强度影响接收时刻的情况。
第三种，根据终端之前进行LMU测量并发送的历史测量信息，确定第一信息。
图9所示信息处理方法示出了另一种第一信息的获取方式。如图9所示，在执行S604之前，该方法还包括如下步骤：
S60332，网络设备检测历史测量信息中是否存在终端上报的第一信息；若是，执行S60334；若否，执行S60336。
其中，历史测量信息为终端之前进行测量并发送给网络设备的测量信息。
S60334，网络设备获取历史测量信息中记录的终端上报的第一信息。
S60336，网络设备指示终端进行LMU测量以获取第一信息。
可知，S60334与S60336为并列的实现步骤，二者在实际实现时，可择一执行。此外，S60336步骤的实现可以前述第一种方式和/或第二种方式实现，不再赘述。
图9所示的实现方式无需在生成第一配置信息之前向终端请求进行LMU测量，简化了生成第一配置信息之前的处理步骤，有利于提高处理效率，节省系统资源。
此外，图9所示实现方式还可以有一种优选的实现方式：网络设备也可在获取到的历史测量信息中记录的终端上报的各LMU信息中，按照各LMU的信号强度，筛选出信号强度大于或者等于预设的信号强度阈值的部分LMU，并将筛选出的部分LMU的信息作为第一信息，并据此生成第一配置信息。
除前述三种获取第一信息的方式之外，在一个优选的实现场景中，考虑到基于UTDOA的定位测量一般需要至少N个LMU反馈的接收时刻，其中，N为进行UTDOA定位测量所需要的LMU的最小数目，因此，在实际实现时，网络设备还可以对第一信息所对应的LMU的数目是否满足最小数目进行验证。
此时，该方法还包括如下步骤：网络设备判断第一信息对应的LMU的数目是否大于或者等于定位测量所需LMU的最小数目；若LMU的数目小于最小数目，网络设备发送通知消息至定位实体，通知消息用于通知定位实体终端当前所处位置不满足定位条件。反之，若LMU的数目大于或者等于该最小数目，则可按照图6～图9所示步骤实现UTDOA定位测量。该方式能够保证网络设备配置并发送给终端的第一配置信息能够满足UTDOA定位测量的最低要求，避免了由于LMU的数目不够，导致定位实体进行终端定位时的接收时刻的数目不足进而导致无法定位的情况。
此外，在网络设备获取到前述第一信息后，即可确定可用于进行定位测量的LMU，需注意，这些可用于定位测量的LMU也不同于前述目标LMU，二者可能相同，或者，可能不同；但是，这些可用于定位测量的LMU中包含目标LMU。这是由于，第一配置信息仅用于指示终端在哪一上行参考信号资源与波束方向上发送定位信号，而定位实体具体利用哪些LMU发送的接收时刻最终完成对终端的定位不是终端可确定的。
因此，在前述生成的第一配置信息中，仅包括第一映射关系即可实现本方案，这是由于在定位测量过程中，终端无需确定每个波束方向对应于哪一个LMU，这对终端而言是非必须的。
当然，在一个优选的实现场景中，也可将在第一配置信息中携带第二映射关系，其中， 第二映射关系为上行参考信号资源与LMU之间的映射关系。例如，可以为上行参考信号资源与LMU的标识信息之间的映射关系。又例如，还可以为上行参考信号资源与LMU编号之间的映射关系。在这种实现场景中，第一配置信息中包含的映射关系可以为：上行参考信号资源-终端能测量到的LMU的下行参考信号的编号信息或索引信息-LMU，此时，终端可根据第一配置信息确定自身发送的定位信号的接收方与波束方向，更有针对性。
除针对终端生成并发送的第一配置信息之外，网络设备还可以基于前述已决定为终端配置的上行参考信号资源，反馈一个response消息给定位实体。
此时，可以参考图10所示的信息处理方法的流程示意图。如图10所示，该方法除包括如图6所示流程之外，还包括：
S6072，网络设备发送第二配置信息至定位实体，第二配置信息包括：上行参考信号资源与LMU的第二映射关系。
S6074，定位实体接收第二配置信息。
S6076，定位实体根据第二配置信息，在各候选LMU中确定目标LMU。
也就是说，定位实体确定目标LMU时，仅能在网络设备上报的各候选LMU中进行挑选确定。本申请对于目标LMU的确定原则无限定，可以根据预设的算法，例如前述将LMU的信号强度与预设阈值比较的算法；或者，也可以根据LMU的位置确定，或者，也可以输出给处理人员，由处理人员手动选择亦可。
S6078，定位实体发送测量配置信息至目标LMU，测量配置信息中携带上行参考信号资源。
在一个优选的实现场景中，第二配置信息中还包括前述第一映射关系。此时，定位实体可还可进一步确定各上行参考信号资源对应的波束方向，在一定程度上能够避免目标LMU处定位信号接收错误的情况。如此，当第一配置信息中也包括第二映射关系时，第一配置信息与第二配置信息相同，其包含的映射关系均可以为：上行参考信号资源-终端能测量到的LMU的下行参考信号的编号信息或索引信息-LMU。
在如图10所示的实现方式中，网络设备发送的第二配置信息主要用以通知定位实体终端会在哪些上行参考信号资源上发送定位信号，以及，这些上行参考信号资源与LMU的关系，如此，在该实现方案中，定位实体可以自由挑选目标LMU，也就是，能够挑选到更符合自身定位需求的LMU作为目标LMU。
如图10所示的实现方式可以与前述任意一种多多种实现方式组合实现，不再赘述。而通过网络设备关于第一配置信息和第二配置信息的发送和配置，能够使得最终确定的各目标LMU能够确实接收到终端发送的定位信号，如此，各目标LMU可以记录接收时刻，并将接收时刻发送给定位实体，由定位实体根据预设算法实现对终端的定位，解决了现有技术中无法在NR系统中实现基于UTDOA的终端定位的问题。
