The LMF network element can also manage and configure the base station or the positioning management unit, and realize the configuration of the positioning reference signal.
本申请所涉及的用户设备UE可以表示任意适用的终端设备，可以包括(或可以表示)诸如无线发送/接收单元(wireless transmit/receive unit，WTRU)、移动站、移动节点、移动设备、固定或移动签约单元、寻呼机、移动电话、手持设备、车载设备、可穿戴设备、掌上电脑(personal digital assistant，PDA)、智能手机、笔记本型电脑、计算机、触摸屏设备、无线传感器或消费电子设备等设备。此处的“移动”站/节点/设备表示与无线(或移动)网络连接的站/节点/设备，而并不一定与该站/节点/设备的实际移动性有关。The user equipment UE involved in this application can represent any applicable terminal equipment, and can include (or can represent) such as a wireless transmit/receive unit (WTRU), mobile station, mobile node, mobile device, fixed or Mobile subscription units, pagers, mobile phones, handheld devices, vehicle-mounted devices, wearable devices, PDAs (personal digital assistants, PDAs), smart phones, notebook computers, computers, touch screen devices, wireless sensors, or consumer electronic devices.

The interfaces and connections in this architecture can include: LTE-Uu, NR-Uu, NG-C, and NLs. Among them, NG-C is the control plane connection between RAN and AMF network elements, LTE-Uu is the protocol interface between ng-eNB and UE, NR-Uu is the protocol interface between UE and gNB, and NLs is the LMF network The protocol interface between the element and the AMF network element.
在所有定位用户设备UE的方法中，观察到达时间差(observed time difference of arrival，OTDOA)方法被广泛使用。该方法的原理是，当***中存在三个或三个以上的基站时，通过测量至少三个基站中的任意两个基站的无线信号到达被定位UE的传播时间差，来计算该被定位UE到该任意两个基站的距离差。Among all methods for locating the user equipment UE, the Observed Time Difference of Arrival (OTDOA) method is widely used. The principle of this method is that when there are three or more base stations in the system, by measuring the propagation time difference between the wireless signals of any two of the at least three base stations to reach the positioned UE, the position of the positioned UE is calculated. The distance difference between any two base stations.
从数学的观点来看，该被定位UE的运动轨迹，就是以该任意两个基站为焦点、以其距离差为定差的曲线。被定位用户设备通过对至少三个基站的测量与计算，可以得到至少两条曲线，而被定位UE的位置就是至少两条曲线的交点。From a mathematical point of view, the trajectory of the UE being located is a curve that takes the any two base stations as the focus and the distance difference as the fixed difference. The positioned user equipment can obtain at least two curves by measuring and calculating at least three base stations, and the position of the positioned UE is the intersection of the at least two curves.
如图2所示出的，在传统的通信***架构下的一种用户定位的方法，可以包括如下步骤：As shown in Fig. 2, a user positioning method under the traditional communication system architecture may include the following steps:
201、定位管理功能网元(location management function，LMF)请求被定位UE附近的多个基站发送用于OTDOA定位的辅助信息。201. A location management function (location management function, LMF) requests multiple base stations near the UE to be located to send auxiliary information for OTDOA positioning.
202、多个基站在收到请求后向LMF网元发送各自的定位辅助信息，例如发送各自的定位参考信号(position reference signal，PRS)的配置。202. After receiving the request, the multiple base stations send their respective positioning assistance information to the LMF network element, for example, sending their respective positioning reference signal (position reference signal, PRS) configuration.
203、LMF网元再将接收到的定位辅助信息发送给被定位UE。203. The LMF network element then sends the received positioning assistance information to the positioned UE.
204、LMF网元向被定位UE发起定位信息测量请求。204. The LMF network element initiates a positioning information measurement request to the positioned UE.
205、被定位UE测量多个基站信号到达时间差完成测量并将测量信息发送LMF网元。205. The positioned UE measures the arrival time difference of signals from multiple base stations to complete the measurement and sends the measurement information to the LMF network element.
206、LMF网元基于被定位UE上报的测量信息计算被定位UE的位置。206. The LMF network element calculates the position of the positioned UE based on the measurement information reported by the positioned UE.
如上所述，在传统的通信***架构下，OTDOA定位方法的应用过程需要LMF网元和多个基站之间以及LMF网元和被定位UE之间进行多次交互。所以，在传统的通信***架构下，难以降低定位技术的时延。As described above, under the traditional communication system architecture, the application process of the OTDOA positioning method requires multiple interactions between the LMF network element and multiple base stations, and between the LMF network element and the UE being located. Therefore, under the traditional communication system architecture, it is difficult to reduce the time delay of the positioning technology.
此外，下一代无线基站(next generation NodeB,gNB)或者下一代演进型基站(next generation-evolved NodeB,ng-eNB)采用集中式单元(central unit or control unit，CU)和分布式单元(distributed unit，DU)分离的网络架构，也就是说gNB或者ng-eNB可以由一个CU和一个或多个DU构成，一个CU可同时与一个或多个的DU连接。In addition, the next generation radio base station (next generation NodeB, gNB) or the next generation-evolved NodeB (ng-eNB) adopts a centralized unit (central unit or control unit, CU) and a distributed unit (distributed unit). , DU) separate network architecture, that is to say, the gNB or ng-eNB can be composed of one CU and one or more DUs, and one CU can be connected to one or more DUs at the same time.
如图3所示，图3示出了一种5G通信***中的CU/DU分离的架构示意图。5G通信***包括下一代核心网(next generation core，NGC)和连接NGC的无线接入网(radio access network，RAN)，连接NGC的RAN包括gNB和ng-eNB，为了便于说明，图3中仅示出了一个gNB和一个ng-eNB。As shown in FIG. 3, FIG. 3 shows a schematic diagram of a CU/DU separation architecture in a 5G communication system. The 5G communication system includes the next generation core (NGC) and the radio access network (RAN) connected to NGC. The RAN connected to NGC includes gNB and ng-eNB. For ease of description, only One gNB and one ng-eNB are shown.
一个gNB或者ng-eNB可以由一个集中式单元(central unit，CU)和一个或多个分布式单元(distributed unit，DU)构成。比如，如图3所示的一个gNB或者ng-eNB由一个CU和两个DU构成。其中，CU和DU之间通过F1接口进行连接。A gNB or ng-eNB may be composed of a centralized unit (CU) and one or more distributed units (DU). For example, a gNB or ng-eNB as shown in FIG. 3 is composed of one CU and two DUs. Among them, the CU and DU are connected through the F1 interface.
CU和DU的功能切分可以按照协议栈进行切分。其中一种可能的方式是将无线资源控制(radio resource control，RRC)以及分组数据汇聚协议(packet data convergence protocol，PDCP)层和业务数据适应(service data adaptation protocol，SDAP)层部署在 CU。无线链路层控制协议(radioLink control，RLC)、媒体接入控制(media access control，MAC)、物理层(physicallayer，PHY)部署在DU。The function division of CU and DU can be divided according to the protocol stack. One possible way is to deploy radio resource control (RRC), packet data convergence protocol (PDCP) layer and service data adaptation protocol (SDAP) layer in the CU. The radio link layer control protocol (radioLink control, RLC), media access control (media access control, MAC), and physical layer (physical layer, PHY) are deployed in the DU.
相应地，CU具有RRC、PDCP和SDAP的处理能力。DU具有RLC、MAC、和PHY的处理能力。值得注意的是，上述功能切分只是一个例子，还有可能有其他切分的方式。例如，CU包括RRC、PDCP、RLC和SDAP的处理能力，DU具有MAC、和PHY的处理能力。又例如CU包括RRC、PDCP、RLC、SDAP和部分MAC(例如加MAC包头)的处理能力，DU具有PHY和部分MAC(例如调度)的处理能力。CU、DU的名字可能会发生变化，只要能实现上述功能的接入网节点都可以看做是本申请中的CU、DU。Correspondingly, the CU has the processing capabilities of RRC, PDCP and SDAP. DU has RLC, MAC, and PHY processing capabilities. It is worth noting that the above function segmentation is just an example, and there may be other segmentation methods. For example, the CU includes the processing capabilities of RRC, PDCP, RLC, and SDAP, and the DU has the processing capabilities of MAC and PHY. For another example, the CU includes the processing capabilities of RRC, PDCP, RLC, SDAP, and part of the MAC (for example, adding a MAC packet header), and the DU has the processing capability of PHY and part of the MAC (for example, scheduling). The names of CU and DU may change, as long as the access network node that can realize the above-mentioned functions can be regarded as the CU and DU in this application.
目前，在CU和DU分离的网络架构下如何支持定位功能尚未进行研究，因此如何在CU-DU分离的网络架构下满足5G定位的低时延、高精度的问题需要有相应的方案来支持。基于图1和图3所示的网络架构，下面将对本申请实施例提供的定位UE的方法进行具体的介绍。At present, how to support the positioning function under the separated network architecture of CU and DU has not yet been studied. Therefore, how to meet the low-latency and high-precision problems of 5G positioning under the separated CU-DU network architecture requires corresponding solutions to support. Based on the network architectures shown in FIG. 1 and FIG. 3, the method for positioning UE provided in the embodiments of the present application will be specifically introduced below.
