具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚,下面将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、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提 下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例可以应用于各种通信系统,例如:先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。
参照图1,图1为本申请实施例中提供的一种无线通信系统的架构示意图。本实施例提供的无线通信系统包括终端设备101和网络设备102。
可选的,终端设备101可以为指各种形式的用户设备、接入终端、用户单元、用户站、移动站、移动台(mobile station,简称MS)、远方站、远程终端、移动设备、终端设备(terminal equipment)、无线通信设备、用户代理或用户装置。还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,简称SIP)电话、无线本地环路(Wireless Local Loop,简称WLL)站、掌上电脑(Personal Digital Assistant,简称PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,简称PLMN)中的终端设备等,本申请实施例对此并不限定。

目前,终端设备常见的定位需求一般可以分为两大场景,一般商业场景和工业物联网(Industrial Internet of Things,简称IIoT)场景。针对一般商业场景,要求的定位精度一般小于1m。而针对IIoT场景,定位的精度需要小于0.2cm。由此,需要对现有定位技术的定位精度做进一步增强,以提升终端设备的定位精度。
为了解决上述技术问题,在本申请中,终端设备通过定位服务器发送的定位校准信息,对终端设备已确定的终端位置信息进行校准,从而可以提升终端设备的定位精度。下面采用详细的实施例进行说明。

本申请实施例中,终端设备在接收到上述定位校准信息之后,获取终 端设备自身当前已确定的终端位置信息,然后在上述定位校准信息中查找出与该终端位置信息匹配的定位校准值,并将该定位校准值确定为终端设备对应的目标定位校准值。
可以理解的是,定位服务器可以预先测量并确定多个参考位置信息对应的定位校准值,然后将各个参考位置信息与各个定位校准值之间的对应关系作为上述定位校准信息发送至终端设备。终端设备在获取到自身当前已确定的终端位置信息之后,在上述定位校准信息中的各个参考位置信息中查找与该终端位置信息匹配的目标参考位置信息,然后根据各个参考位置信息与各个定位校准值之间的对应关系,确定出上述目标参考位置信息对应的定位校准值,进而得到终端设备对应的目标定位校准值。
