具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
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)。
图1是适用于本申请实施例的一种通信系统的架构的示意图。
例如，如图1的(a)所示，该架构例如是第五代系统(the 5h generation system，5GS)。该5GS包括终端设备、(无线)接入网((radio)access network，(R)AN)设备、移动性管理网元、位置管理网元、数据管理(data management)网元、位置移动网关中心、用户面的的定位中心(supl positioning center、用户面的位置中心、外部客户端、用户面网元，以及一些图1的(a)未示出的设备，如网络功能存储功能(network function repository function，NRF)设备等。上述5GS中的设备也可以称为5G核心网设备。

3、移动性管理网元：主要用于移动性管理和接入管理等，如用户位置更新、用户注册网络、用户切换等。例如，移动性管理网元可以接收终端设备的非接入层(non-access stratum，NAS)信令(包括移动管理(mobility management，MM)信令和会话管理(session management，SM)信令)和接入网设备的相关信令(例如，与移动性管理网元交互的基站粒度的N2信令)，完成用户的注册流程和SM信令的转发以及移动性管理。移动性管理网元还可用于实现移动性管理实体(mobility management entity，MME)中除会话管理之外的其它功能。例如，合法监听、或接入授权(或鉴权)等功能。
在5G通信系统中，该移动性管理网元可以是接入和移动性管理功能(access and mobility management function，AMF)网元，在未来通信系统如第六代(the 6th generation，6G)通信系统中，移动性管理网元仍可以是AMF网元，或有其它的名称，本申请不做限定。

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。
在下文示出的实施例中，终端设备之间的接口以PC5接口进行举例，除非特别说明，通过PC5接口使用测距、通过PC5接口进行测量、通过PC5接口执行测距、通过PC5接口获取测量信息或相对位置信息、通过PC5接口使用测距获取测量信息或相对位置信息可代表类似的含义。
目前，核心网中的位置管理网元能够提供的是终端设备的绝对位置信息，本申请实施例提供了一种无线通信的方法和装置，能够获取设备之间的相对位置信息，进而支持更多的应用场景。以下首先对本申请实施例提供的无线通信的方法进行说明。
图2是本申请实施例提供的一种无线通信的方法的示意性流程图。
S210，第二设备向第一设备发送第一请求消息，对应地，第一设备接收来自第二设备的第一请求消息。

该相对位置信息可以包括以下至少一项：相对定位、相对距离、相对角度。
或者，该第一请求消息用于请求第一终端设备和第二终端设备之间的测量信息，该测量信息用于确定该相对位置信息。
该测量信息可以与测量方式相关，例如，该测量方式为测距(ranging)方式、或者说侧行测距(sidelink ranging)方式，第一终端设备和第二终端设备之间通过其之间的接口(例如PC5接口)进行定位，那么该测量信息可以包括对该接口的信号的相关参数进行测量，例如信号传输时间、信号传输周期、信号发送角度、信号接收角度等能够用于确定相对位置信息的参数。
可选地，该第一请求消息可以包括以下信息中的至少一项：第一终端设备的标识信息、第二终端设备的标识信息、测量需求信息、测量信息类型、测量类型信息、触发条件信息和动作信息。
其中，第一终端设备的标识信息和第二终端设备的标识信息可以用于第一设备确定获取哪些终端设备之间的相对位置信息。应理解，在第二设备请求获取两个以上终端设备之间的相对位置信息时，该第一请求消息可以包括两个以上的终端设备的标识信息。在以下的实施例中，将以请求两个终端设备之间的相对位置信息进行介绍，两个以上的终端设备的相对位置信息的确定方式与两个终端设备的类似，为了简便，在此不再赘述。
本申请实施例对终端设备的标识信息的具体表现形式不作限定。例如，终端设备的标识信息可以是外部标识信息，例如一般公共订阅标识符(generic public subscription identifier，GPSI)(如5G中涉及的手机号)或移动用户综合业务数字网(mobile subscriber integrated services digital network，MSISDN)(如4G中涉及的手机号)，核心网网元可以将该外部标识信息转化为内部标识信息，例如用户永久标识符(subscriber permanent identifier，SUPI)(5G中涉及的终端SIM卡标识)、国际移动用户识别码(international mobile subscriber identity，IMSI)(4G中涉及的终端SIM卡标识)、或者全球唯一临时UE标识(globally unique temporary UE identity，GUTI)。或者第一请求消息中的终端设备的标识信息也可以是内部标识信息。即，核心网网元接收的终端设备的标识信息(例如外部标识)与发送的终端设备的标识信息(例如内部标识)可以具有不同的表现形式。
测量需求信息用于指示响应时间需求、定位精度需求、QoS等级需求、定位维度需求等。例如，响应时间需求可以是指示需要获取相对位置信息或者测量信息的时间或时延或者频率，该定位精度需求可以指示该相对距离的精度，例如小于或等于1米，定位维度需求可以指示该相对位置信息为一维定位、二维定位或三维定位。进而，第一设备 可以根据测量需求信息确定如何进行测距定位。另外，在本申请实施例中，精度也可以理解为准确度。
测量信息类型用于指示第一请求消息请求的是测量信息或相对位置信息，或者说，测量信息类型用于指示第一请求消息请求的是侧行测距业务，该侧行测距业务与相对位置信息或者测量信息对应。进而第一设备可以根据该测量类型信息确定进行测距，并返回测量信息或相对位置信息。
测量类型信息用于指示相对位置信息的类型，相对位置信息的类型是指相对距离信息、相对角度信息、相对定位信息。进而第一设备可以根据测量类型信息确定需要测量哪些参数以确定该相对位置信息。
触发条件信息用于指示第一终端设备和/或第二终端设备在相对位置信息满足第一条件的情况下执行第一动作，动作信息用于指示该第一动作。例如，该触发条件信息可以指示两个车辆的相对距离小于预设阈值时，两个车辆执行报警动作。再例如，该触发条件信息可以指示当车辆和手机的相对距离小于预设阈值时，该车辆执行开锁动作。
S220，第一设备响应于该第一请求消息，向第二设备发送该相对位置信息或者该测量信息，对应地，第二设备接收来自第一设备的响应于该第一请求消息的相对位置信息或者测量信息。
应理解，第一设备响应于第一请求消息是指：第一设备根据第一请求消息请求的内容向第二设备发送该请求的内容。即若第一请求消息请求测量信息，则第一设备向第二设备发送测量信息，若第一请求消息请求相对位置信息，则第一设备向第二设备发送相对位置信息。
当第二设备请求的是测量信息，并接收来自第一设备的第一设备时，该方法200还可以包括步骤S230。
可选地，S230，第二设备根据测量信息确定相对位置信息。
例如，该测量信息包括第一终端设备和第二终端设备通过PC5接口传输的信号的传输时间，那么第二设备可以根据该传输时间计算得出相对距离。本申请不对根据测量信息确定相对位置信息的方式作出任何限定。
在本申请实施例中，第一设备可以是该第一终端设备、第二终端设备、第三终端设备、移动性管理网元(如图1所示的AMF网元)或者位置移动网关中心网元(例如图1所示的GMLC网元)。第二设备可以是该第一终端设备、第二终端设备、第三终端设备、应用功能网元(例如图1所示的AF网元)，其中，第一、第二和第三终端设备为不同的终端设备。

或者，再例如，第三终端设备可以向AMF网元发送NAS消息，该NAS消息包括该相对位置信息，该NAS消息还可以包括AF网元的标识信息和NEF网元的标识信息。如果NAS消息中未包括NEF网元的标识信息，AMF网元可以从第三终端设备的上下文信息中获取NEF网元的标识信息，或者AMF网元可以为第三终端设备选择一个NEF网元。进而AMF网元可以通过NEF网元向AF网元发送该相对位置信息。
或者，再例如，第三终端设备可以向AMF网元发送NAS消息，该NAS消息包括该相对位置信息，该NAS消息还可以包括AF网元的标识信息和GMLC网元的标识信息。如果NAS消息中未包括GMLC网元的标识信息，AMF网元可以从第三终端设备的上下文信息中获取GMLC网元的标识信息，或者AMF网元可以为第三终端设备选择一个GMLC网元。进而AMF网元可以通过GMLC网元向AF网元发送该相对位置信息。

例如，该第一请求消息是请求相对位置信息的位置请求消息，第三终端设备通过第三终端设备与第一终端设备之间的PC5接口向第一终端设备发送该位置请求消息。
有关第一请求消息的内容可以参见步骤S210中的介绍，在此不再赘述。

可选地，当S410中的第一请求消息还包括触发条件信息和/或动作信息时，可选地，该方法还可以包括步骤S440。
可选地，S440，在相对位置信息满足第一条件的情况下，第一终端设备执行第一动作。
该第一条件可以是触发条件信息指示的条件或者预设置的条件，该第一动作可以是动作信息指示的动作或者预设置的动作。
应理解，虽然图4中未示出，第一请求消息中的触发条件信息还可以指示第二终端设备在相对位置信息满足第二条件(可以与第一条件相同或者不同)的情况下执行第二动作(可以与第一动作相同或者不同)。即第一请求消息中的触发条件信息和动作信息可以指示一个或多个终端设备执行相应的动作，需要执行动作的终端设备可以通过其他终端设备或者核心网网元获取该触发条件信息、动作信息和相对位置信息并执行相应的动作。
