背景技术
无源物联网(passive internet of thing，PIOT)是由新型节能的标签(tag)终端和读写器组成的通信系统。读写器可以远程读取标签终端的信息。无源物联网的维护成本较低，设备小型化。因此，无源物联网广泛应用于制造业、物流业、电力和畜牧业等。例如，无源物联网可以应用于仓储场景。读写器需要对标签终端的位置进行测量，从而便于进行物料的查询和高价值货物的管理，实现库位级的定位。具体的定位精度要求在2至3米。

可选的，对于ORAN系统中的网元，各个网元可以实现如下述表1所示的协议层功能。
表1

下面介绍接入网设备的CU和DU的架构。接入网设备包括至少一个CU和至少一个DU。可选的，接入网设备还包括至少一个RU。
下面以接入网设备包括一个CU和一个DU为例进行介绍。CU具有核心网的部分功能，CU可以包括CU-CP和CU-UP。CU和DU可以根据其实现的无线网络的协议层功能进行配置。例如，CU被配置为用以实现分组数据汇聚层协议(packet data convergence protocol，PDCP)层及以上协议层(例如，RRC层和/或SDAP层的功能。DU被配置为用以实现PDCP层以下协议层(例如，RLC层、MAC层、和/或物理(physical，PHY)层)的功能。又例如，CU被配置为用以实现PDCP层以上协议层(如RRC层和/或SDAP层)的功能，DU被配置为用以实现PDCP层及以下协议层(例如RLC层、MAC层、和/或PHY层等)的功能。
当CU包括CU-CP和CU-UP时，CU-CP用于实现CU的控制面功能，CU-UP用于实现CU的用户面功能。例如CU被配置为用以实现PDCP层、RRC层和SDAP层的功能时，CU-CP用于实现RRC层功能和PDCP层的控制面功能，CU-UP用于实现SDAP层功能和PDCP层的用户面功能。
CU-CP可以与核心网中用于实现控制面功能的网元交互。核心网中用于实现控制面功能的网元可以是接入和移动性功能网元，例如5G移动通信系统中的接入和移动功能(access and mobility management function，AMF)。所述接入和移动性功能网元用于负责移动网络中的移动性管理，如终端设备的位置更新、终端设备的注册网络、终端设备的切换等。CU-UP可以与核心网中用于实现用户面功能的网元交互。核心网中用于实现用户面功能的网元，例如，5G移动通信系统中的用户功能(user plane function，UPF)，用于负责终端设备中数据的转发和接收。
以上CU，DU的配置仅仅是一种举例，也可以根据需要配置CU，DU具有的功能。例如，可以将CU或者DU配置为具有更多协议层的功能，或者将CU或DU配置为具有协议层的部分处理功能。例如，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。再例如，可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如，按时延划分，将处理时间需要满足较小时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
DU和RU可以合作共同实现PHY层的功能。一个DU可以和一个或多个RU相连。DU和RU所具有的功能可以根据设计被配置为多种方式。例如，DU被配置用于实现基带功能，RU被配置用于实现中射频功能。再例如，DU被配置为用以实现PHY层中的高层功能，RU被配置为实现PHY层中的低层功能或者实现该低层功能和射频功能。物理层中的高层功能可以包括物理层的一部分功能，该部分功能更加靠近MAC层，物理层中的低层功能可以包括物理层的另一部分功能，该部分功能更加靠近中射频侧。
需要说明的是，第一网络设备可以是上述示出的设备或装置，也可以是上述示出的设备或装置中的部件(例如，芯片)、模块、或单元，具体本申请不做限定。
需要说明的是，上述示出了第一网络设备为接入网设备的实现方式。实际应用中，第一网络设备也可以是其他网络设备。例如，第一网络设备为核心网设备，该核心网设备集成读写器。
核心网设备用于对第一装置的位置进行定位计算和管理，和/或，对第一装置进行管理和控制。例如，核心网设备为LMF、TMF或TMF/LMF，还可以是新定义的网元，具体本申请不做限定。
本申请中，第一装置的EPC用于唯一标识该第一装置，该第一装置被盘存时通过该第一装置的EPC 区别于其他装置。例如，第一装置为标签终端，该标签终端的EPC用于该标签终端被盘存时区别于其他标签终端。可选的，第一装置的EPC可以是64位、96位或256位，具体本申请不做限定。每一位为一个比特。
下面结合图2所示的实施例介绍读写器盘存标签终端的流程。请参阅图2，盘存流程包括如下步骤：
201、读写器发送选择命令。该选择命令包括读写器选中的标签终端的掩码。
具体的，读写器广播选择命令。标签终端接收到该选择命令之后，判断选择命令中携带的掩码是否包含该标签终端的掩码，如果包含，则表示该标签终端被选中。该标签终端改变其盘存标志。例如，该标签终端可以将其盘存标志置为0。
202、读写器发送盘存(Query)命令，以协定盘存的数据率、编码方式等。标签终端接收到该盘存命令之后，标签终端重置其时隙计数器，具体重置为一个随机数。
在步骤202之后，标签终端每接收到一次该读写器发送的盘存命令，该时隙计数器的计数减一。当该时隙计数器的计数等于0时，则执行下述步骤203。
203、标签终端向读写器发送16位的随机数(random number 16，RN16)。
204、读写器接收到该RN16之后，读写器向标签终端发送确认信息(acknowledgecharacter，ACK)。
205、标签终端向读写器发送该标签终端的EPC。
相应的，读写器读取该EPC。那么，标签终端退出本次盘存流程，等待下次被选中。
标签终端的信号处理能力较弱，无法实现复杂的信号处理算法。因此标签终端的定位能力受限，传统的定位方法无法直接应用于标签终端。例如，标签终端无法进行下行定位测量。因此，如何对标签终端进行定位以满足定位需求，是亟待解决的问题。
另一方面，传统的定位方法的流程复杂，需要交互很多信息实现对定位测量量的获取，从而确定用户的位置。此外，由上述图2所示的盘存过程不支持定位信息的获取。因此，在盘存过程中或盘存过程之后不支持定位。无法支持盘存过程中或盘存过程之后的定位需求。本申请提供了相应的技术方案，具体可以参阅后文实施例的相关介绍。
下面结合具体的实施例介绍本申请的技术方案。
图3为本申请实施例定位测量方法的第一个实施例示意图。请参阅图3，方法包括：

在该实现方式中，如果根据第一装置发送的定位参考信号对第一装置进行定位测量，而第一装置不具备复杂的信号处理算法的能力(例如，第一装置无法自主生成序列)，那么第一网络设备可以为第一装置配置用于生成定位参考信号的序列。从而便于第一装置基于该序列生成定位参考信号。
可选的，在该实现方式中，第一配置信息还包括以下至少一项：定位参考信号的频域信息、或定位参考信号的发送次数。
