背景技术
实际工程部署室内基站的过程中，由于存在人工安装位置错误、规划位置点位不可安装等原因，会造成预先规划的站点位置与实际安装位置不一致等情况。从而，运维人员无法通过安装设计图纸获取区域内全部室内基站的实际安装位置，不利于室内基站的后续运维，并会对站点设备信息资产的自动化、数字化管理产生影响。
目前，运维或排障时，运维人员可根据施工队安装过程中记录的信息，查找控制室内基站的控制节点，再从控制节点的接口去查找室内基站的位置。
然而，该查找方式效率较低，且一旦施工队发生更换，所记录的安装信息极易丢失，查找室内基站的位置就更为困难。

具体实施方式
下面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清楚、完整的描述。
为了更好的理解本申请实施例公开的位置确定方法，对本申请实施例适用的通信系统进行描述。
本申请实施例可应用于长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、第六代(6th generation，6G)移动通信系统等5G之后演进的系统等、卫星通信及短距等无线通信系统中，系统架构如图1所示。无线通信系统可以包括一个或多个网络设备，以及一个或多个终端设备。无线通信系统也可以进行点对点通信，如多个终端设备之间互相通信。
可理解的，本申请实施例提及的无线通信系统包括但不限于：窄带物联网(narrow band-internet of things，NB-IoT)系统、长LTE系统，5G/6G移动通信系统的三大应用场景：增强移动宽带(enhanced mobile broadband，eMBB)、超可靠低时延通信(ultra reliable low latency communication，URLLC)和海量机器类通信(massive machine type of communication，mMTC)，无线保真(wireless fidelity，WiFi)系统等。
本申请实施例中，网络设备是具有无线收发功能的设备，用于与终端设备进行通信，可以是LTE中的演进型基站(evolved Node B，eNB或eNodeB)，或者是5G/6G网络中的基站或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的基站、宽带网络业务网关(broadband network gateway，BNG)、汇聚交换机或者非第三代合作伙伴项目(3rd generation partnership project，3GPP)接入设备等。可选的，本申请实施例中的网络设备可以包括各种形式的基站，例如：宏基站、微基站(也称为小站)、中继站、接入点、未来实现基站功能的设备、WiFi系统中的接入点(access point，AP)、传输接收点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心以及设备到设备(device-to-device，D2D)、车辆外联(vehicle-to-everything，V2X)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备、5G之后演进的通信系统中实现基站功能的设备、接入回传一体化(integrated access and backhaul，IAB)，还可以包括云接入网(cloud radio access network，C-RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)、非陆地通信网络(non-terrestrial network，NTN)通信系统中的网络设备，即可以部署于高空平台或者卫星，还可以是构成接入节点的各类设备，如有源天线处理单元(active antenna unit，AAU)、基带单元(baseband unit，BBU)等，本申请实 施例对此不作具体限定。
网络设备可以和核心网设备进行通信交互，向终端设备提供通信服务。核心网设备例如为5G网络核心网(core network，CN)中的设备。核心网作为承载网络提供到数据网络的接口，为终端提供通信连接、认证、管理、策略控制以及对数据业务完成承载等。
本申请实施例所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。终端设备也可称为终端。终端设备也可以指用户设备(user equipment，UE)、接入终端、用户单元(subscriber unit)、用户代理、蜂窝电话(cellular phone)、智能手机(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、智能销售点(point of sale，POS)机、客户终端设备(customer-premises equipment，CPE)、机器类型通信(machine type communication，MTC)终端、高空飞机上搭载的通信设备、可穿戴设备、无人机、机器人、D2D中的终端、车到一切(vehicle to everything，V2X)中的终端、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端或者未来通信网络中的终端设备等，本申请不作限制。
本申请实施例适用于包括第一网络设备和多个第二网络设备的通信场景。其中，第一网络设备可为上述无线通信系统中的网络设备，第一网络设备可以看作是基站控制单元，可实现基站控制指令发送和信号处理。第二网络设备为室内基站，比如为皮基站射频拉远单元(pico remote radio unit，pRRU)，pRRU用于室内基站的射频拉远单元，实现射频信号处理功能。
本申请实施例也可应用到雷达组网系统中计算多部雷达的部署位置的场景中。
本申请公开的实施例将围绕包括多个设备、组件、模块等的系统来呈现本申请的各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
当前，对室内基站的日常运维和故障排查时，运维人员可根据施工队安装过程中记录的信息，查找控制室内基站的控制节点(比如射频拉远单元汇聚节点(Remote Radio Unit Hub，RHUB))，再从控制节点的接口去查找相应室内基站的位置，但该查找方式效率较低。其中，RHUB是用于进行数据的汇聚和转发，以便配置多个pRRU进行室内多个楼层或区域的无线覆盖。因此，RHUB是控制多个pRRU的控制节点。
运维人员还可携带测试设备沿预先设计的测试路线，在待测pRRU附近的多个点位进行信号强度测量，以确定待测pRRU的位置信息。图2为对待测pRRU附近的N个点位进行信号强度测量的示意图。运维人员基于测试出的接收信号的强度，以及空间路径损耗的经验模型，计算出不同测试点位与待测pRRU之间的距离信息，再根据测试设备记录的测试点位的位置坐标，通过多点距离定位方式确定待测pRRU的位置信息。该待测pRRU的位置信息确定过程依赖空间路径损耗经验模型，如果待测pRRU附近的空口信道环境与空间路径损耗经验模型匹配误差较大，会对待测pRRU的位置产生较大误差。
运维人员还可使用测距仪器测量每个待测pRRU到参考原点(环境中某个基准点)或参考面(环境中某个基准面)的距离，完成pRRU位置坐标的标定。该测量方式耗时长、成本高、效率低，且容易引入人为操作误差，无法实现站点自动化运维。
此外，RHUB与pRRU之间的连接依靠人工连线，容易发生RHUB端口与pRRU连线错误等情况。例如，图3a为预先规划的RHUB与pRRU之间的连接示意图。如图3a所示，在预先规划的RHUB与pRRU之间的连接关系中，RHUB的逻辑端口1与逻辑小区-1中的pRRU-1连接，RHUB的逻辑端口2与逻辑小区-1中的pRRU-2连接，RHUB的逻辑端口3与逻辑小区-2中的pRRU-3连接，RHUB的逻辑端口4与逻辑小区-2中的pRRU-4连接。图3b为RHUB与pRRU之间的实际物理连接示意图。如图3b所示，RHUB与pRRU之间的实际物理连接中，RHUB的逻辑端口1与逻辑小区-1中的pRRU-1连接，RHUB的逻辑端口2与逻辑小区-1中的pRRU-3连接，RHUB的逻辑端口3与逻辑小区-2中的pRRU-2连接，RHUB的逻辑端口4与逻辑小区-2中的pRRU-4连接。RHUB与pRRU之间的物理连接与预先规划的连接拓扑不一致会使得pRRU查找识别困难，也会导致网络干扰加剧，造成网络性能指标下降和用户体验恶化。
本申请实施例提供一种位置信息确定方法。该位置信息确定方法中，第二网络设备向多个第二网络设备中每个第二网络设备发送第一信息和第二信息，第一信息用于指示第二网络设备确定导频信号通过该第 二网络设备的发送通道和接收通道的第一时延，第二信息用于指示第二网络设备向一个或多个第三网络设备发送导频信号，以及接收来自一个或多个第三网络设备的导频信号。多个第二网络设备中的每个第二网络设备接收第一信息和第二信息。每个第二网络设备根据导频信号确定第一时延，以及通过接收导频信号确定一个或多个第二时延。每个第二网络设备将该第二网络设备的第一时延，以及一个或多个第二时延反馈给第一网络设备。从而第一网络设备根据各第二网络设备之间的空口时延，确定每个第二网络设备的位置信息，各第二网络设备之间的空口时延是根据每个第二网络设备的第一时延和一个或多个第二时延确定的。
可见，第一网络设备可通过每个第二网络设备反馈的第一时延和一个或多个第二时延确定多个第二网络设备中每个第二网络设备的位置信息。该方式与通过人工测量确定每个第二网络设备的位置信息的方式相比，可提高确定多个第二网络设备的位置信息的效率，以及提高每个第二网络设备的位置信息的精确度。
本申请实施例提出一种位置信息确定方法，图4是该位置信息确定方法的交互示意图。该位置信息确定方法从第一网络设备和多个第二网络设备的交互角度进行阐述。该位置信息确定方法包括但不限于以下步骤：
S101.第一网络设备向多个第二网络设备中每个第二网络设备发送第一信息和第二信息，第一信息用于指示第二网络设备确定导频信号通过该第二网络设备的发送通道和接收通道的第一时延，第二信息用于指示第二网络设备向一个或多个第三网络设备发送导频信号，以及接收来自一个或多个第三网络设备的导频信号。相应的，多个第二网络设备中的每个第二网络设备接收第一信息和第二信息。
其中，第三网络设备是多个第二网络设备中除该第二网络设备之外的网络设备。
多个第二网络设备中的每个第二网络设备均包括发送通道和接收通道，发送通道用于发送信号，接收通道用于接收信号。对于每个第二网络设备而言，第一时延是导频信号通过该第二网络设备的发送通道和接收通道的时延，即第一时延是该第二网络设备通过自身发送通道向自身接收通道发送导频信号的时延。
示例性的，图5是多个第二网络设备包括pRRU-1和pRRU-2，第一网络设备包括控制模块，第一网络设备的控制模块与pRRU-1和pRRU-2的交互示意图。如图5所示，第一网络设备通过控制模块向pRRU-1和pRRU-2发送第一信息和第二信息。pRRU-1和pRRU-2的发送通道时延分别为T1和T2，pRRU-1和pRRU-2的接收通道时延分别为R1和R2，pRRU-1和pRRU-2的自环回空口时延分别为C1和C2。pRRU-1的自环回空口时延是指导频信号在pRRU-1内部流转时的时延，pRRU-2的自环回空口时延是指导频信号在pRRU-2内部流转时的时延。
第一时延是导频信号通过第二网络设备的发送通道和接收通道的时延，也可理解为是导频信号通过该第二网络设备的发送通道、自环回空口和接收通道的时延，该自环回空口是导频信号在该第二网络设备的内部流转的空口。那么，对于图5而言，导频信号通过pRRU-1的发送通道、自环回空口和接收通道的时延，即pRRU-1的第一时延t11为T1+C1+R1；导频信号通过pRRU-2的发送通道、自环回空口和接收通道的时延，即pRRU-2的第一时延t22为T2+C2+R2。
第一网络设备向每个第二网络设备发送第一信息，有利于每个第二网络设备根据导频信号确定第一时延，进而有利于第一网络设备获得用于确定每个第二网络设备的位置信息所需的每个第二网络设备的第一时延。
第一网络设备向每个第二网络设备发送的第二信息用于指示该第二网络设备向一个或多个第三网络设备发送导频信号，以及接收来自一个或多个第三网络设备的导频信号，可理解为：每个第二网络设备的第二信息用于指示该第二网络设备向多个第二网络设备中除该第二网络设备之外的网络设备发送导频信号，以及接收来自多个第二网络设备中除该第二网络设备之外的网络设备的导频信号。该方式可使得第一网络设备控制多个第二网络设备中的每个第二网络设备之间互相发送导频信号，从而有利于每个第二网络设备通过接收来自其他网络设备的导频信号确定第二时延，进而有利于第一网络设备获得用于确定每个第二网络设备的位置信息所需的每个第二网络设备的一个或多个第二时延。
示例性的，多个第二网络设备包括pRRU-1、pRRU-2和pRRU-3。第一网络设备向pRRU-1发送的第二信息用于指示pRRU-1向pRRU-2和pRRU-3发送导频信号，以及接收来自pRRU-2和pRRU-3的导频信号；第一网络设备向pRRU-2发送的第二信息用于指示pRRU-2向pRRU-1和pRRU-3发送导频信号，以及接收来自pRRU-1和pRRU-3的导频信号；第一网络设备向pRRU-3发送的第二信息用于指示pRRU-3向pRRU-1和pRRU-2发送导频信号，以及接收来自pRRU-1和pRRU-2的导频信号。
一种可选的实施方式中，多个第二网络设备中的每个第二网络设备被预先配置多个定向波束，每个第 二网络设备的多个定向波束包括多个第一波束和多个第二波束。从而每个第二网络设备可通过多个定向波束发送信号和接收信号，可提升每个第二网络设备发射信号和接收信号的波束增益，即提升各第二网络设备之间的无线链路空口质量。
一种可选的实施方式中，多个第二网络设备中的每个第二网络设备被预先配置多个定向波束时，第二信息具体用于指示第二网络设备在多个第一时隙上分别采用不同的第一波束向一个或多个第三网络设备中的每个第三网络设备发送导频信号，以及在多个第二时隙上分别采用不同的第二波束接收来自每个第三网络设备的导频信号。
也就是说，多个第二网络设备中的每个第二网络设备被预先配置多个定向波束时，第一网络设备通过第二信息，控制每个第二网络设备向一个或多个第三网络设备中的每个第三网络设备发送导频信号时，在多个第一时隙上分别采用不同的第一波束向该第三网络设备发送导频信号；以及接收来自每个第三网络设备的导频信号时，在多个第二时隙上分别采用不同的第二波束接收来自该第三网络设备的导频信号。
示例性的，图6是第一网络设备包括控制模块，第一网络设备通过控制模块向pRRU-1发送第二信息的示意图。如图6所示，该pRRU-1被配置了四个方向的定向波束，定向波束1、定向波束2、定向波束3和定向波束4。从而第一网络设备可通过控制模块向pRRU-1发送第二信息，以控制pRRU-1在不同的时隙上采用不同的定向波束发送导频信号，以及接收导频信号。例如，第二信息用于指示pRRU-1在不同的时隙上分别采用定向波束1、定向波束2、定向波束3和定向波束4向pRRU-2发送导频信号，以及在不同时隙上分别采用定向波束1、定向波束2、定向波束3和定向波束4接收来自pRRU-2的导频信号。
示例性的，多个第二网络设备包括pRRU-1、pRRU-2和pRRU-3。针对pRRU-1，第三网络设备为pRRU-2和pRRU-3，第一网络设备通过第二信息向pRRU-1指示在时隙1和时隙2上分别采用波束1和波束2向pRRU-2发送导频信号，在时隙3和时隙4上分别采用波束3和波束4接收来自pRRU-2的导频信号；以及在时隙5和时隙6上分别采用波束1和波束2向pRRU-3发送导频信号，在时隙7和时隙8上分别采用波束3和波束4接收来自pRRU-3的导频信号。
第一网络设备通过第二信息，控制每个第二网络设备在多个第一时隙上分别采用不同的第一波束向该第三网络设备发送导频信号，以及在多个第二时隙上分别采用不同的第二波束接收来自该第三网络设备的导频信号，可使得每个第二网络设备根据接收信噪比最大原则，确定一个或多个第二时延，从而有利于提高各第二网络设备之间距离的计算精度，进而有利于提高各第二网络设备的位置信息的精度。
可理解的，第一信息和第二信息可以是不同的控制信息，也可以是同一个控制信息，本申请实施例对此不做限定。第一信息和第二信息均可理解为是第一网络设备向每个第二网络设备下发的控制信令。
S102.第二网络设备根据导频信号确定第一时延。
其中，该第二网络设备是多个第二网络设备中的任意一个网络设备。
可理解的，每个第二网络设备的第一信息用于指示该第二网络设备确定导频信号通过该第二网络设备的发送通道和接收通道的第一时延，从而多个第二网络设备中的每个第二网络设备根据导频信号确定第一时延。
第二网络设备根据导频信号确定第一时延，包括：使导频信号通过第二网络设备的发送通道和接收通道，根据导频信号从第二网络设备的发送通道发送的时间，以及通过接收通道接收到该导频信号的时间，确定第一时延。
第一时延也可理解为是导频信号从该第二网络设备的发送通道到该第二网络设备的接收通道的时长。从而，每个第二网络设备将导频信号从该第二网络设备的发送通道到该第二网络设备的接收通道的时长，确定为该第二网络设备的第一时延。
S103.第二网络设备向一个或多个第三网络设备发送导频信号。
可理解的，每个第二网络设备向多个第二网络设备中除该第二网络设备之外的网络设备发送导频信号，以使得每个第二网络设备均接收来自多个第二网络设备中其他网络设备的导频信号。
示例性的，多个第二网络设备包括pRRU-1、pRRU-2和pRRU-3，pRRU-1向pRRU-2和pRRU-3发送导频信号，pRRU-2向pRRU-1和pRRU-3发送导频信号，pRRU-3向pRRU-1和pRRU-2发送导频信号。
一种可选的实施方式中，第二网络设备向一个或多个第三网络设备发送导频信号，包括：在多个第一时隙上采用不同的第一波束向一个或多个第三网络设备中的每个第三网络设备发送导频信号。也就是说，第二网络设备在不同时隙上分别采用不同的第一波束向每个第三网络设备发送导频信号。
示例性的，多个第二网络设备包括pRRU-1、pRRU-2和pRRU-3。针对pRRU-1，第三网络设备为pRRU-2和pRRU-3，pRRU-1在时隙1和时隙2上分别采用波束1和波束2向pRRU-2发送导频信号，以及在时隙 5和时隙6上分别采用波束1和波束2向pRRU-3发送导频信号。
S104.第二网络设备接收来自一个或多个第三网络设备的导频信号，并确定一个或多个第二时延，一个或多个第二时延中各第二时延分别是导频信号从各第三网络设备的发送通道到该第二网络设备的接收通道的时延。
每个第二网络设备均向多个第二网络设备中除该第二网络设备之外的网络设备发送导频信号，从而每个第二网络设备可接收来自多个第二网络设备中除该第二网络设备之外的网络设备的导频信号，即每个第二网络设备可接收来自一个或多个第三网络设备的导频信号。
每个第二网络设备的各第二时延分别是导频信号从第三网络设备的发送通道到该第二网络设备的接收通道的时延，可理解为：各第二时延分别是导频信号从各第三网络设备的发送通道到该第二网络设备的接收通常的时长。从而每个第二网络设备可通过各第三网络设备向该第二网络设备发送导频信号的时间，与接收来自该第三网络设备的导频信号的时间，确定接收来自该第三网络设备的导频信号的第二时延。每个第二网络设备可接收来自一个或多个第三网络设备的导频信号，从而每个第二网络可确定一个或多个第二时延。
示例性的，多个第二网络设备包括pRRU-1、pRRU-2和pRRU-3。对于pRRU-1而言，pRRU-1可根据pRRU-2向pRRU-1发送导频信号的时间，以及接收来自pRRU-2的导频信号的时间，确定第二时延#1。pRRU-1还可根据pRRU-3向pRRU-1发送导频信号的时间，以及接收来自pRRU-3的导频信号的时间，确定第二时延#2。类似的，pRRU-2和pRRU-3均可分别确定两个第二时延。
一种可选的实施方式中，第二网络设备接收来自一个或多个第三网络设备的导频信号，包括：在多个第二时隙上分别采用第二波束接收来自一个或多个第三网络设备中每个第三网络设备的导频信号。也就是说，第二网络设备可在不同的时隙上分别采用不同的第二波束接收来自每个第三网络设备的导频信号。
示例性的，多个第二网络设备包括pRRU-1、pRRU-2和pRRU-3。针对pRRU-1，第三网络设备为pRRU-2和pRRU-3，pRRU-1在时隙3和时隙4上分别采用波束3和波束4接收来自pRRU-2的导频信号，以及在时隙7和时隙8上分别采用波束3和波束4接收来自pRRU-3的导频信号。
可理解的，每个第二网络在不同时隙上采用不同的第一波束向每个第三网络设备发送导频信号，以及在不同时隙上采用不同的第二波束接收来自每个第三网络设备的导频信号时，每个第二网络设备向各第三网络设备发送导频信号所采用的多个第一波束，与各第三网络设备接收来自该第二网络设备的导频信号所采用的多个波束可视为一组波束对。
示例性的，多个第二网络设备包括pRRU-1、pRRU-2和pRRU-3。针对pRRU-1，第三网络设备为pRRU-2和pRRU-3。pRRU-1在时隙1上采用波束1向pRRU-2发送导频信号，相应的，pRRU-2在时隙1上采用波束1′接收来自pRRU-1的导频信号，波束1和波束1′可组成波束对1；pRRU-1在时隙2上采用波束2向pRRU-2发送导频信号，相应的，pRRU-2在时隙2上采用波束2′接收来自pRRU-1的导频信号，波束2和波束2′可组成波束对2。pRRU-1在时隙3上采用波束3向pRRU-3发送导频信号，相应的，pRRU-3在时隙3上采用波束3′接收来自pRRU-3的导频信号，波束3和波束3′可组成波束对3；pRRU-1在时隙4上采用波束4向pRRU-3发送导频信号，相应的，pRRU-3在时隙4上采用波束4′接收来自pRRU-1的导频信号，波束4和波束4′可组成波束对4。
该实施方式下，每个第二网络设备的各第二时延具体是最优波束对所对应的时延，该最优波束对是多个第一波束和多个第二波束中接收信噪比最大的波束对。也就是说，每个第二网络在不同时隙上采用不同的第一波束向每个第三网络设备发送导频信号，以及在不同时隙上采用不同的第二波束接收来自每个第三网络设备的导频信号时，每个第二网络设备的各第二时延是该第二网络设备采用最优波束对接收来自第三网络设备的导频信号时的时延，且该第二网络设备采用最优波束对接收来自该第三网络设备的导频信号时，其接收信噪比与采用其他波束对接收来自该第三网络设备的导频信号时的信噪比相比，该第二网络设备采用最优波束对接收来自该第三网络设备的导频信号的信噪比最大。
示例性的，多个第二网络设备包括pRRU-1、pRRU-2。针对pRRU-1，第三网络设备为pRRU-2。pRRU-1在时隙1上采用波束1向pRRU-2发送导频信号，相应的，pRRU-2在时隙1上采用波束1′接收来自pRRU-1的导频信号；pRRU-1在时隙2上采用波束2向pRRU-2发送导频信号，相应的，pRRU-2在时隙2上采用波束2′接收来自pRRU-1的导频信号。pRRU-2在时隙2上采用波束2′接收来自pRRU-1的导频信号时的信噪比，大于在时隙1上采用波束1′接收来自pRRU-1的导频信号时的信噪比。那么，pRRU-2接收来自pRRU-1的导频信号时的第二时延是波束2和波束2′组成的波束对所对应的时延，也可理解为是：pRRU-1在时隙2上采用波束2向pRRU-2发送导频信号，以及pRRU-2在时隙2上采用波束2′接收来自pRRU-1 的导频信号时的时延。
该实施方式可提高一个或多个第二时延中每个第二时延的精度，进而有利于提高第一网络设备根据每个第二网络设备的一个或多个第二时延确定的每个第二网络设备的位置信息的精度。
本申请实施例不限定S102至S104的执行顺序。也就是说，S102可在S103和S104之前执行，也可在S103和S104之后执行。同理，S103可在S102和S104之前执行，也可在S102和S104之后执行；S104可在S102和S103之前执行，也可在S102和S103之后执行。
S105.第二网络设备发送第一时延，以及一个或多个第二时延。相应的，第一网络设备接收每个第二网络设备的第一时延，以及一个或多个第二时延。
可理解的，多个第二网络设备中的每个第二网络设备向第一网络设备发送该第二网络设备的第一时延，以及一个或多个第二时延，以使得第一网络设备获得确定每个第二网络设备的位置信息所需的时延信息。
一种可选的实施方式中，每个第二网络设备还可记录一个或多个最优波束对，即记录接收来自每个第三网络设备的导频信号时，接收信噪比最大时对应的最优波束对的波束指向和角度信息。
可选的，每个第二网络设备还可向第一网络设备发送该第二网络设备的一个或多个最优波束对。相应的，第一网络设备还可接收来自每个第二网络设备的一个或多个最优波束对。该方式有利于第一网络设备确定每个第二网络设备的位置信息时，参考每个第二网络设备的一个或多个最优波束对中每个最优波束对的波束指向和角度信息，进而有利于提高每个第二网络设备的位置信息的精度。
S106.第一网络设备根据各第二网络设备之间的空口时延，确定每个第二网络设备的位置信息，各第二网络设备之间的空口时延是基于每个第二网络设备的第一时延，以及一个或多个第二时延确定的。
一种可选的实施方式中，第一网络设备还可根据多个第二网络设备的第一时延和一个或多个第二时延，补偿多个第二网络设备中每两个第二网络设备之间的接收通道的时延，再根据补偿后的每两个第二网络设备之间的接收通道的时延，确定各第二网络设备之间的空口时延。
第一网络设备根据多个第二网络设备的第一时延和一个或多个第二时延，补偿多个第二网络设备中每两个第二网络设备之间的接收通道的时延，也可理解为：根据多个第二网络设备中每两个第二网络设备的第一时延和一个或多个第二时延，使其该两个第二网络设备之间的接收通道的时延对齐；还可理解为：使每两个第二网络设备的接收通道的时延相等时，对该两个第二网络设备中的一个网络设备的接收通道的时延进行补偿。
示例性的，如图5所示，多个第二网络设备包括pRRU-1和pRRU-2。图5中，H12表示pRRU-1发送，pRRU-2接收的空口时延；H21表示pRRU-2发送，pRRU-1接收的空口时延。假设pRRU-1确定的第一时延为t11，第二时延为t21；pRRU-2确定的第一时延为t22，第二时延为t12。那么每个时延存在如下关系：
t11＝T1+C1+R1         (1)
t21＝T2+H21+R1       (2)
t22＝T2+C2+R2        (3)
t12＝T1+H12+R2         (4)
第一网络设备基于pRRU-1与pRRU-2之间收发空口的信道互易性可知：H12＝H21，且若忽略不同pRRU自环回空口时延C1、C2的差异影响，即C1≈C2，通过公式(1)至公式(4)可得到：
基于公式(5)可知，第一网络设备可根据pRRU-1的第一时延t11和第二时延t21，以及pRRU-2的第一时延t22和第二时延t12，确定pRRU-1的接收通道与pRRU-2的接收通道之间的差值。从而第一网络设备可使得pRRU-1的接收通道的时延R1与pRRU-2的接收通道的时延R2相等，对齐pRRU-1与pRRU-1之间的接收通道的时延。即第一网络设备使得pRRU-1的接收通道的时延R1与pRRU-2的接收通道的时延R2相等时，补偿pRRU-1或pRRU-1的接收通道的时延。例如，第一网络设备将pRRU-1的接收通道的时延R1增大R1-R2，或者而将pRRU-1的接收通道的时延R2减小R1-R2。
第一网络设备补偿pRRU-1与pRRU-1之间的接收通道的时延后，基于上述公式(1)至公式(4)，可计算获得pRRU-1与pRRU-2之间的空口时延。从而第一网络设备可根据pRRU-1与pRRU-2之间的空口时延，确定pRRU-1与pRRU-2之间的距离，进而可根据pRRU-1与pRRU-2之间的距离，确定pRRU-1 和pRRU-2的位置信息。例如，pRRU-1的位置信息是预先设定的，那么第一网络设备可根据pRRU-1与pRRU-2之间的距离，以及pRRU-1的已知位置信息，确定pRRU-2的位置信息。
可见，第一网络设备可根据多个第二网络设备的第一时延和一个或多个第二时延，补偿多个第二网络设备中每两个第二网络设备之间的接收通道的时延，再根据补偿后的每两个第二网络设备之间的接收通道的时延，确定各第二网络设备之间的空口时延。进而第一网络设备可根据各第二网络设备之间的空口时延，确定每个第二网络设备的位置信息。
一种可选的实施方式中，第一网络设备根据各第二网络设备之间的空口时延，确定每个第二网络设备的位置信息，包括：根据各第二网络设备之间的空口时延，确定每两个第二网络设备之间的距离；根据每两个第二网络设备之间的距离，以及一个或多个第四网络设备的位置信息，确定每个第二网络设备的位置信息。第四网络设备是多个第二网络设备中已知位置信息的网络设备。
也就是说，第一网络设备根据各第二网络设备之间的空口时延，确定每两个第二网络设备之间的距离，再基于每两个第二网络设备之间的距离，以及已知的少量第二网络设备的位置信息，确定多个第二网络设备中其余网络设备的位置信息。
一种可选的实施方式中，第一网络设备根据每两个第二网络设备之间的距离，以及一个或多个第四网络设备的位置信息，确定每个第二网络设备的位置信息，包括：根据每两个第二网络设备之间的距离，以及每个第二网络设备的一个或多个最优波束对的波束信息，确定多个第二网络设备之间的空间拓扑结构；根据每两个第二网络设备之间的距离、空间拓扑结构，以及一个或多个第四网络设备的位置信息，确定每个第二网络设备的位置信息。
可理解的，第一网络设备根据每两个网络设备之间的距离，以及每个第二网络设备的一个或多个最优波束对的波束信息，利用多维尺度变换技术，确定多个第二网络设备之间的空间拓扑结构，即各第二网络设备之间的相对位置结构关系。
示例性的，多个第二网络设备包括pRRU-1、pRRU-2、pRRU-3和pRRU-4，第一网络设备根据每两个pRRU之间的距离，以及每个pRRU的一个或多个最优波束对的波束信息，利用多维尺度变换技术，确定4个pRRU之间的空间拓扑结构如图7所示，即图7为4个pRRU之间的空间拓扑结构示意图。
第一网络设备再根据每两个第二网络设备之间的距离、多个第二网络设备之间空间拓扑结构，以及多个第二网络设备中预先规划的少量第二网络设备的位置信息，对多个第二网络设备之间的空间拓扑结构图进行平移、镜像和旋转等刚体变换操作，确定每个第二网络设备的位置信息。
可见，第一网络设备确定每个第二网络设备的位置信息的实施方式，与通过人工测量确定每个第二网络设备的位置信息的方式相比，可提高确定每个第二网络设备的位置信息的效率，以及可提高每个第二网络设备的位置信息的准确度。
一种可选的实施方式中，第一网络设备还可根据第五网络设备的多个逻辑端口，确定多个逻辑端口中每个逻辑端口对应的第二网络设备，即确定每个逻辑端口与第二网络设备的连接关系。第五网络设备是控制多个第二网络设备的网络设备，比如第五网络设备是RHUB。
可理解的，第一网络设备根据第五网络设备的逻辑端口，指定某个特定的第二网络设备发送导频信号。第一网络设备通过多个第二网络设备除该第二网络设备之外的网络设备对接收信号和空口时延的测量，获得该第二网络设备到其他网络设备的距离。第一网络设备再结合多个第二网络设备之间的空间拓扑结构，确定该第二网络设备在空间拓扑结构中的位置，进而确定指定的逻辑端口所对应的第二网络设备，即确定了与该逻辑端口连接的第二网络设备。
示例性的，图8为第一网络设备确定逻辑端口1所对应的pRRU-1的示意图。如图8所示，第一网络设备通过控制模块控制与逻辑端口1连接的pRRU向其他pRRU发送导频信号，可确定与逻辑端口1连接的pRRU-1与其余pRRU的距离，进而再基于pRRU-1至pRRU-4之间的空间拓扑结构，确定与逻辑端口1连接的pRRU-1为图8中所示的位置。
该实施方式中，第一网络设备可自行确定RHUB的逻辑端口与各pRRU之间的连接关系，无需人工现场逐一测试，可提升后续运维过程中查找和识别故障pRRU的效率。
本申请实施例中，第二网络设备向多个第二网络设备中每个第二网络设备发送第一信息和第二信息，第一信息用于指示第二网络设备确定导频信号通过该第二网络设备的发送通道和接收通道的第一时延，第二信息用于指示第二网络设备向一个或多个第三网络设备发送导频信号，以及接收来自一个或多个第三网络设备的导频信号。多个第二网络设备中的每个第二网络设备接收第一信息和第二信息。每个第二网络设备根据导频信号确定第一时延，以及通过接收导频信号确定一个或多个第二时延。每个第二网络设备将该 第二网络设备的第一时延，以及一个或多个第二时延反馈给第一网络设备。从而第一网络设备根据各第二网络设备之间的空口时延，确定每个第二网络设备的位置信息，各第二网络设备之间的空口时延是根据每个第二网络设备的第一时延和一个或多个第二时延确定的。
第一网络设备可通过每个第二网络设备反馈的第一时延和一个或多个第二时延确定多个第二网络设备中每个第二网络设备的位置信息。该方式与通过人工测量确定每个第二网络设备的位置信息的方式相比，可提高确定多个第二网络设备的位置信息的效率，以及提高每个第二网络设备的位置信息的精确度。
图9是以多个第二网络设备包括pRRU-1、pRRU-2、pRRU-3和pRRU-4，第五网络设备为RHUB为例的系统架构示意图。如图9所示，第一网络设备包括控制模块和数据处理模块，第一网络设备的控制模块和数据处理模块与RHUB连接，RHUB的4个逻辑端口分别与pRRU-1、pRRU-2、pRRU-3和pRRU-4连接。pRRU-1、pRRU-2、pRRU-3和pRRU-4中每个pRRU均包括通道校正模块、发送通道和接收通道。
其中，第一网络设备的控制模块用于调度每个pRRU在指定时隙上发送或接收导频信号，即第一网络设备通过控制模块向每个pRRU发送第一信息和第二信息。此外，第一网络设备的控制模块还用于每个pRRU定向波束的切换选择与调度。第一网络设备的数据处理模块用于收集各pRRU的测量结果，并根据多个pRRU的测量结果构建多个pRRU之间的空间拓扑架构和确定每个pRRU的位置信息。也就是说，第一网络设备的数据处理模块用于接收每个pRRU的第一时延和一个或多个第二时延，并根据多个pRRU的第一时延和一个或多个第二时延，构建多个pRRU之间的空间拓扑架构，以及确定每个pRRU的位置信息。
每个pRRU的通道校正模块用于对接收通道的时延进行校正，即用于对与其他pRRU之间的接收通道的时延进行补偿。每个pRRU的发送通道用于发送信号，接收通道用于接收信号。从图9还可看出，对于pRRU-1而言，pRRU-1可采用定向波束1、定向波束2、定向波束3和定向波束4向其余pRRU发送信号。例如，pRRU-1采用定向波束1、定向波束2、定向波束3和定向波束4向pRRU-2发送导频信号。同理，pRRU-1还可采用定向波束1、定向波束2、定向波束3和定向波束4向pRRU-3和pRRU-4发送信号。
图10是以多个第二网络设备包括pRRU-1、pRRU-2、pRRU-3，且第一网络设备包括数据处理模块和控制模块为例，数据处理模块、控制模块和各pRRU之间的交互示意图。如图10所示，数据处理模块、控制模块和各pRRU之间的交互包括但不限于以下步骤：
S11，第一网络设备通过控制模块向每个pRRU发送第一信息，第一信息用于指示pRRU确定导频信号通过该pRRU的发送通道和接收通道的第一时延。相应的，每个pRRU接收第一信息，并启动该pRRU的通道校正模块，使得导频信号在该pRRU的内部空口环回，并确定第一时延。
S12，第一网络设备通过控制模块向每个pRRU发送第二信息，第二信息用于指示pRRU在特定时隙上发送和接收导频信号。相应的，每个pRRU接收第二信息。
S13，每个pRRU向其他pRRU发送导频信号，接收来自其他pRRU的导频信号，并完成时延估计，确定一个或多个第二时延。
S14，每个pRRU向第一网络设备反馈第一时延和一个或多个第二时延。相应的，第一网络设备通过数据处理模块接收每个pRRU的第一时延和一个或多个第二时延。
S15，第一网络设备的数据处理模块对每个pRRU的第一时延和一个或多个第二时延进行处理，获得各pRRU之间接收通道的时延差。即第一网络设备根据每个pRRU的第一时延和一个或多个第二时延，对每两个pRRU之间接收通道的时延进行补偿。
S16，第一网络设备的数据处理模块根据补偿后的每两个pRRU之间接收通道的时延，确定每两个pRRU之间的空口时延，并根据每两个pRRU之间的空口时延，确定每两个pRRU之间的距离。
S17，第一网络设备的数据处理模块根据每两个pRRU之间的距离，确定多个pRRU之间的空间拓扑关系。
S18，第一网络设备的数据处理模块根据每两个pRRU之间的距离和多个pRRU之间的空间拓扑关系，确定每个pRRU的位置信息。
可见，第一网络设备可通过控制模块控制多个pRRU中的每个pRRU之间互相发送和接收导频信号，从而每个pRRU确定第一时延和一个或多个第二时延，并向第一网络设备反馈该pRRU的第一时延和一个或多个第二时延。进而，第一网络设备可根据多个pRRU的第一时延和一个或多个第二时延，确定每个pRRU的位置信息，而无需依靠运维人员现场测量获得每个pRRU的位置信息，可提高确定多个pRRU的位置信息的效率和精度。
