图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备,如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer,PC)、柜员机或者自助机等终端侧设备,可穿戴式设备包括:智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备,其中,接入网设备12也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备12可以包括基站、WLAN接入点或WiFi节点等,基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例进行介绍,并不限定基站的具体类型。核心网设备可以包含但不限于如下至少之一:核心网节点、核心网功能、移动管理实体(Mobility Management Entity,MME)、接入移动管理功能(Access and Mobility Management Function,AMF)、会话管理功能(Session Management Function,SMF)、用户平面功能(User Plane Function,UPF)、策略控制功能(Policy Control Function,PCF)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function,EASDF)、统一数据管理(Unified Data Management,UDM),统一数据仓储(Unified Data Repository,UDR)、归属用户服务器(Home Subscriber Server,HSS)、集中式网络配置(Centralized network configuration,CNC)、网络存储功能(Network Repository Function,NRF),网络开放功能(Network Exposure Function,NEF)、本地NEF(Local NEF,或L-NEF)、绑定支持功能(Binding Support Function,BSF)、应用功能(Application Function,AF),位置管理功能LMF(location manage function),E-SMLC,NWDAF(network data analytics function)等。需要说明的是,在本申请实施例中仅以NR系统中的核心 网设备为例进行介绍,并不限定核心网设备的具体类型。
为了更好的描述本申请各实施例,首先对以下内容进行介绍:
(1)车联网(vehicle to everything,V2X)
长期演进系统支持副链路传输,图2是本申请实施例提供的副链路的示意图,如图2所示,终端用户设备(User Equipment,UE)之间不通过网络设备进行直接数据传输。即UE之间直接在物理层上进行数据传输。LTE sidelink是基于广播进行通讯的,虽然可用于支持车联网的基本安全类通信,但不适用于其他更高级的V2X业务。5G NR系统将支持更加先进的sidelink传输设计,例如,单播,多播或组播等,从而可以支持更全面的业务类型。
(2)资源分配;NR V2X定义了两种资源分配mode,一种是mode1,为基站调度资源;另一种是mode2,UE自己决定使用什么资源进行传输。此时资源信息可能来自基站的广播消息或者预配置的信息。UE如果工作在基站范围内并且与基站有RRC连接,可以是mode1和/或mode2,UE如果工作在基站范围内但与基站没有RRC连接,只能工作在mode2。如果UE在基站范围外,那么只能工作在mode2,根据预配置的信息来进行V2X传输。
对于mode 2,具体的工作方式如下:
1)TX UE在资源选择被触发后,首先确定资源选择窗口,资源选择窗口的下边界在资源选择触发后的T1时间,资源选择的上边界在触发后的T2时间,其中T2是UE实现的方式在其TB传输的PDB(packet delay budget)内选择的值,T2不早于T1。
2)UE在资源选择的之前,需要确定资源选择的备选资源结合(candidate resource set),根据资源选择窗口内的资源上测量的RSRP与相应的RSRP threshold做对比,如果RSRP低于RSRP threhold,那么该资源可以纳入备选资源集合。
3)资源集合确定后,UE随机在备选资源集合中选择传输资源。另外,UE在本次传输可以为接下来的传输预留传输资源。图3是本申请实施例提供的检测及资源选择或重选流程的示意图,检测及资源选择或重选的具体流程如图3所示。
(3)NR定位是UU口,基于基站和UE之间的信号测量进行的定位;在NR定位增强阶段,支持LOS和NLOS指示信息上报,和多path测量结果上报;但在副链路中如何实现还是不清楚的。
因此,本申请实施例提供的定位方法、装置、终端及通信设备,明确了基于物理副链路的定位参考信号进行终端定位的方式,有效提高定位准确度,同时兼顾了LOS和NLOS指示信息上报,有效减少测量误差。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的定位方法、装置、终端及通信设备进行详细地说明。
