具体实施方式
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作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。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述指定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
为更好理解本申请实施例的方案，首先对一下内容进行介绍：
V2X简介
长期演进(Long Term Evolution，LTE)系统支持旁链路(sidelink，或译为副链路，侧链路，边链路等)传输，即终端(User Equipment，UE)之间直接在物理层上进行数据传输，图1a示出一种包含SL通信的通信系统。LTE sidelink是基于广播进行通讯的，虽然可用于支持车联网(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。
长期演进(Long Term Evolution，LTE)系统从第12个发布版本开始支持旁链路(sidelink，或译为副链路，侧链路，边链路等)，用于终端用户设备(User Equipment，UE)之间不通过网络设备进行直接数据传输。
资源分配
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(Transmit User Equipment，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(Transport Block，TB)传输的包延迟预算(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结合(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 Receiving Power，RSRP)与相应的RSRP门限(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。具体流程如图1b所示。

下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的方法及装置进行详细地说明。

参见图2，本申请实施例提供一种定位方法；
需要说明的是，本申请实施例应用于SL通信场景，涉及的通信设备为SL通信中的一对终端，即第一终端和第二终端，该第一终端和第二终端可以互为发送端或接收端，也就是说，可以是第一终端为发送终端，第二终端为接收终端，或者第一终端为接收终端，第二终端为发送终端；在另一种应用场景中，在SL通信系统内还可以设置调度终端，相应地，第一终端和第二终 端也可以分别为调度终端与发送终端，或者也可以分别为调度终端与接收终端。相应地，可以存在调度终端，调度第一终端发送和/或第二终端接收。或者第一终端是调度终端，第二终端是被调度终端，反之亦然。
或者，第一终端还可以是第二终端的控制节点，例如在组播(Groupcast)中header UE调度一对UE进行传输。
本申请实施例的方法对于上述各类情况均能够使用，下面以方法的执行主体为第一终端进行描述，可以理解的是，该第一终端可以作为SL通信中的发送终端、接收终端或者调度终端。
方法具体步骤包括：步骤201。
步骤201：第一终端根据预设规则，传输SL定位参考信号，或者计算TBS；
在本申请实施例中，SL定位参考信号(SL Positioning Reference Signal，SL-PRS)用于确定第一终端和/或第二终端的位置信息，该第二终端为与第一终端进行SL通信或SL定位的对端终端。
