核心网设备可以包含但不限于如下至少一项: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)、位置服务器、位置管理功能(Location Management Function,LMF),基于演进的服务移动位置中心(Evolved Serving Mobile Location Center,E-SMLC),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。
下面介绍一些本申请实施例涉及的基本概念。
副链路(Sidelink,SL),也称侧链路、边链路或旁链路。如图1所示,侧链路用于终端设备11之间不通过网络侧设备12而直接进行数据传输,且副链路传输是相对于主链路传输而言的,主链路传输包括终端设备11向网络侧设备12发起的上行传输和网络侧设备12向终端设备11发起的下行传输。
LTE sidelink是基于广播进行通讯的,可用于支持车联网(vehicle to everything,V2X)的基本安全类通信,但不适用于其他更高级的V2X业务。5G NR(New Radio)系统支持更加先进的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。
目前,NR sidelink包括但不限于下述至少一种信道:
物理副链路控制信道(physical sidelink control channel,PSCCH);
物理副链路共享信道(physical sidelink shared channel,PSSCH);
物理副链路广播信道(physical sidelink broadcast channel,PSBCH);
物理副链路反馈信道(physical sidelink feedback channel,PSFCH)。
NR sidelink包括但不限于下述至少一种信号:
副链路主同步信号(sidelink Primary Synchronisation Signal,S-PSS);
副链路同步信号(sidelink Synchronization Signal,S-SS);
副链路定位参考信号(sidelink Positioning Reference Signal,SL PRS);
副链路解调参考信号(sidelink Demodulation Reference Signal,SL DMRS);
副链路信道状态信息参考信号(sidelink Channel State Information Reference Signal,SL CSI-RS);
副链路相位跟踪参考信号(sidelink Phase-tracking reference signal,SL PTRS)。
NR V2X定义了两种资源分配模式(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无线资源控制(Radio Resource Control,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)发送终端(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实现的方式在其传输块(transportblock,TB)传输的分组时延预算(packet delay budget,PDB)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集合(candidate resource set),根据资源选择窗口内的资源上测量的参考信号接收功率(reference signal received power,RSRP)与相应的RSRP threshold做对比,如果RSRP低于RSRP门限(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。再有,NR V2X支持链式的资源预留方式,也就是,一个副链路控制信息(Sidelink Control Information,SCI)可以预留当前的资源,最多可以再额外预留两个资源,在下一个资源中,可以再指示两个预留资源。在选择窗内,可以采用动态预留的方式持续预留资源。
图2示出了本申请实施例可应用的一种无线通信系统的传输接口示意图。如图2所示,新一代无线接入网(New Generation Radio Access Network,NG-RAN)可以包括NR节点(gNB)和新一代演进节点B(New Generation evolved Node B,ng-eNB),gNB和ng-eNB之间通过Xn接口通信;在NG-RAN的覆盖范围内(Inside NG-RAN coverage),终端(如UE1和UE2)之间通过PC5接口通信,终端(如UE1或UE2)与网络节点(如gNB或ng-eNB)之间通过Uu接口通信;在NG-RAN的覆盖范围外(Outside NG-RAN coverage),终端(如UE1或UE2)与终端(如UE3)之间通过PC5接口通信。
还需要说明的是,在本申请实施例中,SL定位参考信号(副链路定位参 考信号)是指用于SL定位的参考信号,并不一定仅仅是指SL PRS,SL定位参考信号可以包括但不限于下述至少一种:
副链路定位参考信号(sidelink Positioning Reference Signal,SL PRS);
副链路同步信号块(Synchronization Signal and PBCH block,SL-SSB);
副链路信道状态信息参考信号(sidelink Channel State Information Reference Signal,SL CSI-RS);
副链路相位跟踪参考信号(sidelink Phase-tracking reference signal,SL PTRS);
副链路解调参考信号(sidelink Demodulation Reference Signal,SL DMRS)。

在一个可选的实施例中,所述第二终端可以是基于发现过程确定的可以用于SL定位的终端。
SL定位辅助信息一般是指用于网络侧设备辅助或协助终端实现SL定位的相关信息,下文会以第一SL定位辅助信息为例说明这些SL定位辅助信息具体可以包括哪些信息,此处暂不赘述。
本申请实施例提供的一种基于SL定位辅助信息的通信方法,由于第一终端会向网络侧设备上报第一SL定位辅助信息,使得所述网络侧设备能够基于所述第一SL定位辅助信息向所述第一终端配置SL定位所需信息,所述SL定位所需信息包括SL定位辅助数据和SL定位配置信息中的至少一种,因此,可以使得网络侧设备实现协助SL定位以及为SL定位配置合适的资源中的至少一个目的。
可选地,在所述相关终端包括第二终端的情况下,第一终端上报的第一SL定位辅助信息中包含第二终端的SL定位辅助信息(可称为第二SL定位辅助信息),因此,在步骤301之前,图3A所示的方法还可以包括:第一终端接收所述第二终端发送的第二SL定位辅助信息,所述第二SL定位辅助信息用于所述第一终端确定所述第一SL定位辅助信息。更为具体的,所述第二SL定位辅助信息用于所述第一终端确定所述第一SL定位辅助信息中包含所述第二终端的SL定位辅助信息。
可选地,在所述相关终端包括第二终端的情况下,第一终端上报的第一SL定位辅助信息中包含第二终端的相关信息(如SL定位辅助信息),可能是因为所述第二终端与所述第一终端存在SL连接或所述第一终端通过发现过程发现了所述第二终端可以用于辅助SL定位,所以在第一SL定位辅助信息中包含第二终端的信息。
需要说明的是,第一终端既可以是发送终端(TX UE),也可以是接收终端(RX UE),且在所述相关终端同时包括第一终端和第二终端的情况下,如果所述第一终端为TX UE,则所述第二终端的数量可以是一个以上(一个或多个)。
需要说明的是,第一终端既可以是目标终端(需要定位的终端),也可以是辅助终端。且在所述相关终端同时包括第一终端和第二终端的情况下,如果所述第一终端为辅助终端UE,则所述第二终端中可能包括目标终端,还可能包括其它辅助终端。
下面以第一SL定位辅助信息为例说明SL定位辅助信息具体可以包括哪些信息。

(5)所述第二终端的ID,其中,所述第二终端的ID可以是目的地索引(destination ID)、成员ID(member ID)、5G S-临时移动签约标识(5G S-Temporary Mobile Subscription Identifier,5G-S-TMSI)、应用层识别信息以及小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)等至少之一。其中,若所述第二终端为辅助终端,可选的,还可能包括第二终端的位置信息。
(6)所述相关终端对应的第一时间间隔信息,所述第一时间间隔信息包括第一传输时间间隔信息和第二传输时间间隔信息中的至少一项,其中,所述第一传输时间间隔信息为第一SL定位参考信号与第二SL定位参考信号的传输时间间隔信息,所述第二传输时间间隔信息为第一SL定位参考信号的测量结果上报信息与第一信息的最大传输间隔信息,所述第一SL定位参考信号是所述相关终端发送的SL定位参考信号,所述第二SL定位参考信号是所述相关终端接收的SL定位参考信号,所述第一信息包括SL定位请求信息和SL定位测量信息中的至少一种。

(13)所述相关终端请求或释放的用于SL定位的资源。
(14)所述相关终端倾向的SL定位专用资源池的配置信息。
不难看出,上述14项信息大多是与SL定位参考信号传输相关,因此, 在所述第一SL定位辅助信息包括上述14项信息中至少一项的情况下,网络侧设备可以根据这14项信息向第一终端配置SL定位参考信号相关的信息。
此外,上述信息可能与一个或多个第二终端相关,因此,在所述第一SL定位辅助信息包括一个或多个第二终端的识别信息,网络侧设备可以选择合适的第二终端帮助第一终端或目标终端进行SL定位。
下面参考图3B所示的往返时间测量(RECEPTION-TO-TRANSMISSION,RTT)定位流程示意图、图3C所示的SL RTT定位原理示意图以及图3D所示的SL双RTT或多RTT(RTT Double side RTT/multi-RTT)定位原理示意图中的至少一个,对上述第(6)项中的第一时间间隔信息以及上述第一信息可能的情况进行说明。
如图3B所示,RTT定位过程包括:
步骤1、发起设备(Initiating Device)向响应设备(Responding Device)发起RTT测量请求。
上述发起设备是指定位请求发起设备,响应设备是指定位请求响应设备。可以理解,在SL定位中,发起设备可以是一个终端,响应用设备可以是另一终端,具体的,当发起设备为本申请实施例中的第一终端时,响应设备可以是本申请实施例中的第二终端。
步骤2、响应设备接收RTT测量请求。
响应设备在接收到RTT测量请求后,可以准备接收RTT测量信号。
步骤3、发起设备在t0时刻向响应设备发送RTT测量信号。
步骤4、响应设备测量发起设备发送的RTT测量信号,并获得该RTT测量信号的到达时刻(Time of Arrival,TOA)t1。
步骤5、响应设备在t2时刻向响应设备发送RTT测量信号。
步骤6、响应设备向发起设备发送RX-TX时间差:t2-t1。
可选的,响应设备也可以在t2时刻发送RTT测量信号的有效载荷(payload)中发送RX-TX时间差。
步骤7、发起设备测量响应设备发送的RTT测量信号,获得TOA t3。
步骤8、发起设备计算得到RTT=t3-t0-(t2-t1)。
发起设备计算得到RTT=t3-t0-(t2-t1)后,如果要估计发起设备和响应设备之间的距离,用RTT除以2再乘以光速即可得到。
RTT定位的好处在于,不要求发起设备与响应设备绝对同步。因为,t2与t1只需参考响应设备的同步源,t3与t0只需要参考发起设备的同步源即可。
图3C示出了SL应用RTT进行定位的原理示意图。参考图3C可知,在SL中,发起设备可以是第一终端,接收设备可以是第二终端,第一终端在t0时刻向第二终端发送的RTT测量信号为SL-PRS1,第二终端在t2时刻向第 一终端发送的RTT测量信号为SL-PRS2。
在图3B和图3C的基础上可以知道,在一个例子中,当上述第一时间间隔信息为第一SL定位参考信号与第二SL定位参考信号的传输时间间隔信息(第一传输时间间隔信息)时,该第一时间间隔具体可以是SL-PRS1与SL-PRS2之间的传输时间间隔:T+Treply(如图3C所示);当上述第一时间间隔为第一SL定位参考信号的测量结果上报信息与第一信息的最大传输间隔信息(第二传输时间间隔信息)时,该第一时间间隔可以是SL-PRS1与第一信息的最大传输间隔,其中,第一信息可以是图3B所示的步骤2中的RTT测量请求或步骤4中的RTT测量信息。
