具体实施方式
如前所述，在现有技术中，已经形成了丰富的定位解决方案，既包括基于无线接入网的定位技术，即RAT-dependent定位技术，也包括独立于无线接入网的定位技术，即RAT-independent定位技术。
当前，第三代合作伙伴计(3rd generation partnership project，3GPP)正在研究在5G(即New Radio，NR)中引入V2X。因为5G系统能够提供更大的带宽、更低的时延，可以更好的满足V2X的业务需求。
面向5G，来源于政策监管的需求和商业应用的需求，定位技术在3GPP中得到了进一步讨论，具体的可参考TR 38.855。以覆盖80％的用户为定位基准，政策监管对定位的精度要求稍低，要求水平位置定位误差小于50米、垂直方向的定位误差小于5米、定位时延小于 30秒；商业应用对定位精度提出了更高的要求，要求水平位置定位误差室内小于3米室外小于10米、垂直方向的定位误差小于3米、定位时延小于1秒。
具体地，业界提出的解决方案大致有如下3类：
(1)基于无线接入网(Radio Access Technology，RAT)的定位技术，又具体包括多种方法，例如增强小区标识定位法(Enhanced Cell ID，E-CID)、下行到达时间观测差定位法(Observed Time Difference of Arrival，OTDOA)、上行到达时间观测差定位法(Uplink Time Difference of Arrival，UTDOA)、E-CID+OTDOA、OTDOA+UTDOA等。
(2)独立于无线接入网的定位技术，又具体包括多种方法，例如辅助全球导航卫星系统定位(network-Assisted GNSS methods，A-GNSS)、基于蓝牙(Bluetooth)的定位、基于WiFi的定位、基于定位传感器的惯性测量单元(IMU,Inertial Measurement Unit)定位、A-GNSS+IMU、A-GNSS+WiFi等。
(3)基于RAT和独立RAT的混合定位技术，又具体包括A-GNSS+OTDOA、A-GNSS+UTDOA等多种方法。
在车联网(Vehicle to everything，V2X)的业务需求协议TS 22.186中，对相对定位提出了需求，具体的，支持V2X应用的两个终端间的相对横向定位精度为0.1m，相对纵向定位精度小于0.5m。
另外，3GPP服务与系统(Service and System Aspects，SA1)工作组对短距业务(Ranging service)进行了研究，并形成了研究报告TR 22.855。该报告中的短距业务指的是确定两个UEs的距离和/或一个UE相对于另一个UE的方向。
为支持上述短距定位业务，和V2X下防碰撞等业务需求，需要支持直连链路或者边链路或者侧行链路(sidelink，SL)定位，又称为侧行链路。为支持SL定位，可能需要在SL终端间发送SL定位参考信号，比如SL PRS/SRS/SSB/CSI-RS。因此，SL定位参考信号的 配置、定位参考信号在SL终端间的传输过程，定位参考信号测量以及定位结果的计算等流程都需要确定。
然而，本发明的发明人经过研究发现，在现有技术中，尚不支持基于侧行链路的定位技术，即在SL终端间不支持传输定位参考信号。因此亟需一种通信方法，来使能SL定位参考信号的传输，并提供定位参考信号的配置、传输、测量、定位结果计算等一系列完整方案。
在本发明实施例中，通过发送配置信息获取请求以及接收第一配置信息的步骤，且所述配置信息获取请求与侧行链路定位业务相关，可以对SL定位参考信号的配置等方面进行确定，有效填补现有技术中的空白，并且能够降低定位边链路用户终端的复杂度，提升系统效率。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
参照图1，图1是本发明实施例中一种通信系统架构图。
具体地，在物物直连通信技术或边链路通信技术(Sidelink，SL)中，用户设备(也可以被称为终端设备)和基站设备可以进行通信，用户设备和基站设备之间的链路被称为上行(Uplink)或下行链路(Downlink)，用户设备还可以直接和用户设备进行通信，用户设备和用户设备之间的链路称为直连链路(sidelink，SL)，接口被称为PC5接口。
参照图2，图2是本发明实施例中一种通信方法的流程图。所述通信方法可以用于发送端，还包括步骤S21至步骤S22：
步骤S21：发送配置信息获取请求，所述配置信息获取请求用于获取第一配置信息，所述第一配置信息用于配置第一参考信号，所述第一参考信号用于侧行链路定位业务；
步骤S22：接收所述配置信息获取请求所请求的所述第一配置信息。
其中，所述发送端可以为侧行链路发送UE，还可以为侧行链路接收UE。
在本发明实施例中，上述步骤S21～步骤S22所提供的循环前缀扩展生成方法可以由用户设备所执行。具体的，上述步骤S21～步骤S22可以由用户设备中的基带芯片所执行，或者由用户设备中包含基带芯片的芯片模组所执行。
