具体实施方式
为了便于理解本申请实施例，在介绍本申请实施例之前，先作出以下几点说明。
第一，在本申请实施例中，“指示”可以包括直接指示和间接指示，也可以包括显式指示和隐式指示。将某一消息(如下文所述的第一请求消息)所指示的信息称为待指示信息，则具体实现过程中，对待指示信息进行指示的方式有很多种，例如但不限于，可以直接指示待指示信息，如待指示信息本身或者该待指示信息的索引等。也可以通过指示其他信息来间接指示待指示信息，其中该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分，而待指示信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。
第二，在下文示出的实施例中第一、第二以及各种数字编号仅为描述方便进行的区分，并不用来限制本申请实施例的范围。例如，区分不同的参考信息等。
第三，在下文示出的实施例中，“预先配置”可以通过在设备(例如，终端设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等。
本申请提供的技术方案还可以应用于未来的通信系统，如第六代移动通信系统等。 本申请对此不作限定。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(device to device，D2D)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，车辆与万物(vehicle to everything，V2X)通信(也可以称为车辆网通信)，例如，车辆与车辆(vehicle to vehicle，V2V)通信(也可以称为车到车通信)、车辆与基础设施(vehicle to infrastructure，V2I)通信(也可以称为车到基础设施通信)，车辆与行人(vehicle to pedestrian，V2P)通信(也可以称为车到人通信)，车辆与网络(vehicle to network，V2N)通信(也可以称为车到网络通信)。

在图1的(a)所示的架构中，各设备之间可以通过图中所示的接口通信。如图1的(a)所示，Uu接口为终端设备和(R)AN的通信接口，用于终端设备和(R)AN的通信等；N2接口为接入网设备和移动性管理网元的通信接口，用于接入网设备和移动性管理网元的通信等；NL1接口为移动性管理网元和位置管理网元之间的通信接口，用于位 置定位请求和响应消息的发送等。此外，其他接口与各设备之间的关系如图1中所示，为了简洁，这里不一一详述。
图1的(a)中Uu、N1、N2、N52、NL1、NL2、NL5、NL6、N33、Le等为接口序列号。这些接口序列号的含义可参见第三代合作伙伴计划(3rd generation partnership project，3GPP)以及开放移动联盟(open mobile alliance，OMA)组织标准协议中定义的含义，在此不做限制。
例如，如图1的(b)所示，图1的(b)是设备间通信方式的一个场景的示意图。在图1的(b)中所示的场景中，主要存在两种通信接口，即终端设备121与网络设备110(例如图1中的核心网设备)之间的通信接口(Uu口)和终端设备121与终端设备122之间的通信接口(PC5口)，其中Uu口用于用户设备与基站或路侧单元之间的通信，PC5口用于终端与终端之间的侧行链路通信。Uu口上终端发送数据给基站的链路称为上行链路(uplink)，而终端接收基站发送的数据的链路称为下行链路(downlink)。终端和终端之间的通信接口称为PC5口。PC5口上的终端和终端之间传输数据的链路称为侧行链路(sidelink)或直通链路。侧行链路一般用于设备到设备(device to device，D2D)等可以在设备间进行直联通信的场景，在该场景中，设备之间的数据传输不需要经过基站。车联网(vehicle to everything,V2X)通信可以看成是D2D通信的一种特殊情形。
在Uu口上，终端和基站之间通过无线承载来传输数据和无线资源控制(radio resource control，RRC)信令。其中，用于传输数据的无线承载称为数据无线承载(data radio bearer，DRB)，用于传输RRC信令的承载称为信令无线承载(signaling radio bearer，SRB)。一个无线承载包括分组数据汇聚协议(packet data convergence protocol，PDCP)实体和无线链路控制(radio link control，RLC)承载。其中，一个RLC承载包括一个RLC实体和对应的逻辑信道(Logical Channel,LCH)。无线承载的配置即为该无线承载的PDCP实体，RLC实体和逻辑信道的配置。无线承载的配置需要能够保证通过该无线承载传输的业务的服务质量(quality of service，QoS)要求。在Uu口，无线承载的配置由网络设备为终端配置。
在PC5口上，终端和终端之间也需要通过无线承载来传输数据和RRC信令。PC5口上的无线承载可以称为侧行链路无线承载(sidelink radio bearer，SL RB)。在长期演进(long term evolution，LTE)V2X系统中，PC5口上的无线承载分别由发送端终端和接收端终端自己建立，无线承载的配置通过标准预定义或者由发送端终端和接收端终端自己确定。
需要说明的是，图1的中所涉及的各个设备以及设备之间的通信接口的名称是以目前协议中规定的为例进行简单说明的，但并不限定本申请实施例只能够应用于目前已知的通信系统。因此，以目前协议为例描述时出现的标准名称，都是功能性描述，本申请对于设备、接口或信令等的具体名称并不限定，仅表示设备、接口或者信令的功能，可以对应的扩展到其它系统，比如2G、3G、4G、5G、或未来通信系统中。
上述图1所示的本申请实施例能够应用的架构仅是一种举例说明，适用本申请实施例的架构并不局限于此，任何能够实现上述各个设备的功能的架构都适用于本申请实施例。
还应理解，上述命名仅为便于区分不同的功能而定义，不应对本申请构成任何限定。本申请并不排除在5G网络以及未来其它的网络中采用其他命名的可能。例如，在6G网络中，上述各个设备中的部分或全部可以沿用5G中的术语，也可能采用其他名称等。图1中的各个设备之间的接口名称只是一个示例，具体实现中接口的名称可能为其他的名称，本申请对此不作具体限定。此外，上述各个设备之间的所传输的消息(或信令)的名称也仅仅是一个示例，对消息本身的功能不构成任何限定。

可选地，在第一设备确定定位方式中，第一设备根据第一能力信息、第二能力信息和定位需求确定该定位方式。
