Description

一种通信方法及设备
本申请要求于2018年9月28日提交国家知识产权局、申请号为201811139492.7、申请名称为“一种通信方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请的实施例涉及通信技术领域，尤其涉及一种通信方法及设备。
背景技术
V2X(vehicle to everthing，车与外界)业务是一类车与外界的信息交换的通信业务。其中，V2X场景中，V2X业务的数据可以通过终端设备与终端设备之间的PC5接口以sidelink方式传输，也可以通过Uu口直接与基站传输。在当前R15 LTE V2X(R15 long term evolution，长期演进版本15的V2X)讨论过程中，标准新引入了一些物理侧特性，例如更高阶的调制、发送分集等，而这些特性是R14 LTE V2X的终端设备无法兼容的。这就意味着如果V2X的终端设备采用R15新的物理层特性去传输V2X业务的数据，并不是所有的V2X的终端设备都能够收到，例如R14 LTE V2X的终端设备就无法进行解析。而某些V2X业务的数据，例如，基本的安全相关的信息，是希望所有的V2X终端设备都能够收到并解析出来的，那么，针对这个业务就应该采用所有V2X终端设备都兼容的方式去进行发送。目前标准定义了两套tx profile(发送数据的配置方式)，tx profile 1:终端设备shall use Rel-14 compatible format(use Rel-14 MCS table,not to use Rel-15 feature)终端设备使用R14兼容格式，即使用R14的MCS(modulation and coding scheme,调制与编码策略)表，不使用R15的特性。tx profile 2:终端设备shall use Rel-15 format which is not compatible with Rel-14(rate matching is used.use Rel-15 MCS table)终端设备使用与R14不兼容的R15的格式，即速率匹配使用R15的MCS表。
tx profile是业务(service)粒度的，即对应业务的所有数据都用核心网设备选定的Tx profile进行发送。终端设备的V2X应用层往终端设备AS(Access Stratum，接入层)层发V2X业务的数据时，会同时指示该业务的tx profile，终端设备会按照指示用相应的格式进行V2X业务数据的发送。现有技术只允许核心网设备确定业务的tx profile，而核心网并不感知sidelink(边缘链路或侧行链路)实时的状态，这样tx profile相当于一个静态的配置，这可能会导致业务的传输质量无法获得满足。

具体实施方式
下面将结合本申请实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
在本申请的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。另外，为了便于清楚描述本申请实施例的技术方案，本申请实施例中所述的“第一”和“第二”等是用于区别不同的对象，或者用于区别对同一对象的不同处理，而不是用于描述对象的特定顺序。
V2X业务是一类车与外界的信息交换的通信业务。通常，通过3GPP传输V2X业务的数据，V2X具体包括：V2I(vehicle to infrastructure，车到道路设施)、V2N(vehicle to network，车到网络)、V2P(vehicle to pedestrian，车到人)、V2V(vehicle to vehicle，车到车)。其中，V2I业务中一个参与者是终端设备，另一个参与者是道路设施，例如路边单元(roadside unit，RSU)；V2N业务中一个参与者是终端设备，另一个参与者是服务实体，例如通过网络设备进行通信时，服务实体为应用服务器或应用服务器连接的无线接入网设备；V2P和V2V业务中两个参与者都是终端设备。V2X业务的数据可以通过PC5接口或者Uu接口(空中接口，简称空口)进行传输，其中PC5接口通常为用于终端设备与终端设备等设备端到端数据传输的空中接口，Uu接口通常为用于终端设备与无线接入网设备之间数据传输的空中接口。
参照图1所示，示出了通过PC5接口进行通信的V2X业务的场景(包括：V2V、V2I以及V2P的场景)，这类通信称为V2X sidelink(边缘链路或侧行链路，SL)通信模式，此时SL上传输的业务数据为V2X业务的数据。这时候终端设备可以在支持V2X的小区覆盖范围内，也可以在支持V2X的小区覆盖范围外。终端设备需要被授权 之后才能通过PC5接口(SL接口)进行V2X sidelink通信。通过PC5接口的通信模式进一步分为mode3(模式3)和mode4。mode3模式是V2X终端设备每次传输V2X业务的数据前，都需要跟无线接入网设备去请求资源，由无线接入网设备按序分配资源；mode4是V2X终端设备通过监听方式，竞争获取V2X sidelink资源进行V2X业务的数据发送，不需要无线接入网设备进行调度。当然，此处仅以LTE V2X为例，将PC5接口的通信模式分为mode3和mode4；类似的在NR V2X中，将PC5接口的通信模式分为mode1和mode2。mode1模式是V2X终端设备每次传输V2X业务的数据前，都需要跟无线接入网设备去请求资源，由无线接入网设备按序分配资源；mode2是V2X终端设备通过监听方式，竞争获取V2X sidelink资源进行V2X业务的数据发送，不需要无线接入网设备进行调度。图2示出了，通过Uu接口进行通信的V2X业务的场景(包括：V2V、V2I、V2P以及V2N的场景)，现有技术是发端终端设备将V2X业务的数据通过Uu接口发送给无线接入网设备，无线接入网设备通过核心网侧的APP服务器找到目标终端设备(user equipment，用户设备)，进一步无线接入网设备将V2X业务的数据通过Uu接口发送给目标终端设备。
现有技术定义了LTE V2X，在引入了NR(new radio，新无线)系统之后，通信标准中讨论在NR系统内支持V2X，即NR V2X。NR V2X相比于LTE V2X能够提供更高的可靠性、更低的时延、更大的吞吐，因此可以用来实现一些新的用例，例如自动驾驶、组通信等，即这类业务只能通过NR V2X来通信。而有一些V2X用例中，例如基本的安全相关的通信，是希望所有的V2X的终端设备都能够收到的，因此用LTE V2X来通信会更好。还有一类V2X用例，会是跟制式并不强相关，即在LTE V2X或NR V2X进行传输都是可行的，此时更多的会是依赖于V2X sidelink链路情况来保证传输质量。
在当前R15 LTE V2X讨论过程中，标准新引入了一些物理侧特性，例如更高阶的调制、发送分集等，而这些特性是R14 LTE V2X的终端设备无法兼容的。这就意味着如果V2X的终端设备采用R15新的物理层特性去传输V2X业务的数据，并不是所有的V2X的终端设备都能够收到，例如R14 LTE V2X的终端设备就无法进行解析。而某些V2X业务的数据，例如，基本的安全相关的信息，是希望所有的V2X终端设备都能够收到并解析出来的，那么，针对这个业务就应该采用所有V2X终端设备都兼容的方式去进行发送。目前，标准定义了两套tx profile(发送数据使用的配置信息)，tx profile 1:终端设备shall use Rel-14 compatible format(use Rel-14 MCS table,not to use Rel-15 feature)终端设备使用R14兼容格式，即使用R14的MCS(modulation and coding scheme,调制与编码策略)表，不使用R15的特性。tx profile 2:终端设备shall use Rel-15 format which is not compatible with Rel-14(rate matching is used.use Rel-15 MCS table)终端设备使用与R14不兼容的R15格式，即速率匹配使用R15的MCS表。然而，tx profile是业务粒度的，即对应业务的所有数据都用tx profile限制的方式进行发送。终端设备的V2X应用层往终端设备AS层发V2X业务的数据时，会同时指示该业务的tx profile，终端设备会按照指示用相应的格式进行V2X业务数据的发送。现有技术只允许核心网去确定业务的tx profile，而核心网并不感知sidelink实时的状态，tx profile相当于一个静态的配置，这可能会导致业务的传输质量无法获得满足。
针对上述问题，本申请实施例提供一种通信方法，包括：无线无线接入网设备获取终端设备在侧行链路上传输业务数据使用的配置信息，该配置信息包括以下各项配置参数中的任一项或任几项：终端设备在侧行链路上传输业务数据使用的技术类别、终端设备在侧行链路上传输业务数据使用的空中接口、终端设备在侧行链路上传输业务数据使用的无线接入技术以及终端设备在侧行链路上传输业务数据使用的模式；其中，侧行链路为终端设备和另一个终端设备之间的无线通信链路；无线无线接入网设备根据配置信息生成指示信息，无线无线接入网设备将指示信息发向所述终端设备，以指示终端设备根据指示信息在侧行链路上传输业务数据。这样，现有技术中核心网设备为终端设备静态配置tx profile，而本申请中首先由无线接入网设备获取终端设备在侧行链路上传输业务数据使用的配置信息，例如，该配置信息可以为核心网设备为终端设备配置的或者无线接入网设备根据终端设备的请求为终端设备配置的，由于无线接入网设备可以感知侧行链路实时的状态，因此可以根据配置信息向终端设备发送指示信息时，可以结合侧行链路实时的状态，这样终端设备根据指示信息在侧行链路上传输业务数据，可以提高业务的传输质量。
具体的本申请的实施例提供通信系统，如图3所示，包括无线接入网设备以及终端设备，例如无线接入网设备11、终端设备12(12-1、12-2)。此外，本申请的实施例还包括核心网设备，其中核心网设备可以为LTE系统中的MME，NR系统中的AMF，或者V2X的控制节点(control function)，V2X的控制节点可以属于LTE系统，也可以属于NR系统，也可以同时属于LTE和NR系统。终端设备12-1和终端设备12-2之间可以通过SL传输V2X业务的数据。本申请的实施例可以应用于同时支持LTE以及NR的无线通信系统，无线接入网设备11可以是一个LTE无线接入网设备同时支持LTE和NR V2X，也可以是NR无线接入网设备同时支持LTE和NR V2X；或者如图4所示，该通信系统包括两个无线接入网设备，支持LTE V2X的无线接入网设备21，支持NR V2X的无线接入网设备22。其中，核心网设备用于为终端设备配置配置信息，例如tx profile；无线接入网设备用于根据配置信息向终端设备发送指示信息，例如可以为重写tx profile或者通过其他方式配置终端设备传输V2X业务的数据使用的路径；终端设备根据指示信息传输V2X业务的数据。当采用两个无线接入网设备时，支持LTE V2X的无线接入网设备21为终端设备提供LTE V2X配置，用于传输LTE V2X相关业务的数据，支持NR V2X的无线接入网设备22为终端设备提供NR V2X配置，用于传输NR V2X相关业务的数据，并且，在此之前，无线接入网设备21和无线接入网设备22之间会存在信息的交互。
本申请实施例中的终端设备可以是指能够与无线接入网设备实现信息交互的车载终端(如图5所示的车载终端500)、手机、平板电脑、个人计算机PC、个人数字助理PDA、智能手表、上网本、可穿戴电子设备等，本申请实施例对该设备的具体形式不做特殊限制。图6示出的无线接入网设备可以用于与一个或多个终端设备进行通信，也可以用于与一个或多个具有部分终端设备功能的无线接入网设备进行通信(例如无线接入网设备采用基站时，无线接入网设备为宏基站与微基站，或者无线接入网设备采用接入点时，接入点之间的通信)；无线接入网设备还可以为接入点、节点、节点B、演进节点B(eNB)或某种其它网络实体，并且可以包括以上网络实体的功能中的一 些或所有功能。无线接入网设备为基站时，在采用不同的无线接入技术的系统中，基站的名称可能会有所不同。例如：在LTE网络(或称为4G系统)中，基站的名称为演进的基站(evolved NodeB，eNB或eNodeB)；在3G系统中，基站的名称为基站(Node B)；在下一代无线通信系统(如5G系统)中，基站的名称为gNB。随着通信技术的演进，这一名称可能会变化。此外，在其它可能的情况下，基站可以是其它为终端设备提供无线通信功能的装置。
如图5所示，以车载终端500作为上述终端设备举例，车载终端500具体可以包括：处理器501；还可以根据需要包括射频RF电路502、存储器503、触摸屏504、蓝牙装置505、一个或多个传感器506、无线保真Wi-Fi装置507、定位装置508、音频电路509、通信接口510以及电源装置511中的一个或多个部件。这些部件可通过一根或多根通信总线或信号线(图5中未示出)进行通信。本领域技术人员可以理解，图5中示出的硬件结构并不构成对车载终端500的限定，车载终端500可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。

其中，触控板504-1可采集车载终端500的用户在其上或附近的触摸事件(比如用户使用手指、触控笔等任何适合的物体在触控板504-1上或在触控板504-1附近的 操作)，并将采集到的触摸信息发向其他器件(例如处理器501)。其中，用户在触控板504-1附近的触摸事件可以称之为悬浮触控；悬浮触控可以是指，用户无需为了选择、移动或拖动目标(例如图标等)而直接接触触控板，而只需用户位于设备附近以便执行所想要的功能。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型来实现触控板504-1。
显示器(也称为显示屏)504-2可用于显示由用户输入的信息或提供给用户的信息以及车载终端500的各种菜单。可以采用液晶显示器、有机发光二极管等形式来配置显示器504-2。触控板504-1可以覆盖在显示器504-2之上，当触控板504-1检测到在其上或附近的触摸事件后，传送给处理器501以确定触摸事件的类型，随后处理器501可以根据触摸事件的类型在显示器504-2上提供相应的视觉输出。虽然在图5中，触控板504-1与显示屏504-2是作为两个独立的部件来实现车载终端500的输入和输出功能，但是在某些实施例中，可以将触控板504-1与显示屏504-2集成而实现车载终端500的输入和输出功能。可以理解的是，触摸屏504是由多层的材料堆叠而成，本申请实施例中只展示出了触控板(层)和显示屏(层)，其他层在本申请实施例中不予记载。另外，车载终端500为其他形式的设备如移动终端形式时，触控板504-1可以以全面板的形式配置在车载终端500的正面，显示屏504-2也可以以全面板的形式配置在车载终端500的正面，这样在车载终端500的正面就能够实现无边框的结构。
另外，车载终端500还可以具有指纹识别功能。例如，在车载终端500的正面(例如触摸屏504的下方)配置指纹识别器，或者车载终端500为移动终端时可以在车载终端500的背面(例如后置摄像头的下方)配置指纹识别器。又例如，可以在触摸屏504中配置指纹采集器件来实现指纹识别功能，即指纹采集器件可以与触摸屏504集成在一起来实现车载终端500的指纹识别功能。在这种情况下，该指纹采集器件配置在触摸屏504中，可以是触摸屏504的一部分，也可以以其他方式配置在触摸屏504中。本申请实施例中的指纹采集器件522的主要部件是指纹传感器，该指纹传感器可以采用任何类型的感测技术，包括但不限于光学式、电容式、压电式或超声波传感技术等。
车载终端500还可以包括蓝牙装置505，用于实现车载终端500与其他短距离的设备(例如手机、智能手表等)之间的数据交换。本申请实施例中的蓝牙装置可以是集成电路或者蓝牙芯片等。

图6为本申请实施例提供的一种无线接入网设备的组成示意图，如图6所示，无线接入网设备可以包括至少一个处理器61、收发器62。
下面结合图6对无线接入网设备的各个构成部件进行示例性的介绍：
处理器61是无线接入网设备的控制中心，可以是一个处理器，也可以是多个处理元件的统称。例如，处理器61是一个CPU，也可以是特定集成电路ASIC，或者是被配置成实施本申请实施例的一个或多个集成电路，例如：一个或多个微处理器DSP，或，一个或者多个现场可编程门阵列FPGA。当然，该无线接入网设备还可以包括存储器63。
其中，处理器61可以独立执行本申请中无线接入网设备的功能，也可以通过运行或执行存储在存储器43内的软件程序，以及调用存储在存储器63内的数据，执行无线接入网设备的各种功能。
作为一种实施例，处理器61可以包括一个或多个CPU，例如图中所示的CPU 0和CPU 1。

图6中示出的设备结构并不构成对无线接入网设备的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
基于上述的网络系统以及硬件，本申请的实施例提供一种通信方法，该通信方法。参照图7所示包括如下步骤：
101、无线接入网设备获取配置信息。
其中，配置信息用于终端设备在侧行链路上传输业务数据，配置信息包括以下各项配置参数中的任一项或任几项：终端设备在侧行链路上传输业务数据使用的技术类别、终端设备在侧行链路上传输业务数据使用的空中接口、终端设备在侧行链路上传输业务数据使用的无线接入技术以及终端设备在侧行链路上传输业务数据使用的模式； 其中，侧行链路为终端设备和另一个终端设备之间的无线通信链路。
在一种示例性的方案中，配置信息可以为核心网设备发送给终端设备的，其中，配置信息是以V2X业务为粒度的，即每个V2X业务会有一个对应的配置信息，示例性的，核心网设备预先存储有V2X业务与配置信息(tx proflie)的对应关系，或者，核心网设备根据终端设备的信息和/或V2X业务的信息动态地确定该配置信息。通常，终端设备可以按照核心网设备为其配置的tx profile选择相应的技术类别进行V2X业务的数据传输。例如，tx profile可以指示终端设备在侧行链路上传输业务数据使用的技术类别，示例性的，技术类别可以包含LTE V2X、NR V2X；可选的，技术类别可以包含V2X技术具体的版本信息，例如：R14 LTE V2X、R15 LTE V2X、R16 NR V2X、以及可能的后续演进版本，如R16 LTE V2X、R17 NR V2X等。可选的，如果配置信息仅指示技术类别，而不限定终端设备在侧行链路上传输业务数据使用的模式；则终端设备和无线接入网设备收到该配置信息之后，可以采用两种模式中的任一模式传输V2X业务的数据，即mode1和mode2都均可以被采用。除此之外，配置信息可以包括终端设备在侧行链路上传输业务数据使用的空中接口。例如，tx profile可以指示LTE Uu和/或NR Uu。从实际场景来说，会存在V2X业务只能通过空中接口(Uu)传输的情况，考虑到LTE Uu和NR Uu的区别，两者能够支持的技术类别也有可能不一样。因此，还可以进一步区分模式，例如mode1和/或mode2(LTE V2X中mode3和/或mode4)，因此配置信息可以包括终端设备在侧行链路上传输业务数据使用的模式。两种模式对资源的管理方式不同，导致两种模式对服务质量(quality of service，QoS)的满足是不一样的，简单来说，同等条件下，一般认为mode1可靠性更高，mode2的时延更短。类似的，如果配置信息仅指示模式，而不限定技术类别，终端设备和无线接入网设备可以认为核心网设备仅限定模式，而不限定技术类别，此时可以选择任一技术类别采用限定的模式传输V2X业务的数据。配置信息可以包括终端设备在侧行链路上传输业务数据使用的RAT(radio access technology，无线接入技术)，例如tx profile包括LTE和/或NR。类似的，如果配置信息仅指示RAT，而不指示其他，终端设备和无线接入网设备可以认为只要满足RAT，不管是空中接口或SL口都是可以采用的。基于上述理解，考虑允许核心网设备做更强的控制，因此配置信息可以包括上述配置参数的组合，例如采用的技术类别为R16 NR V2X时采用的模式为mode1；采用技术类别为R15 LTE V2X时采用的模式为mode4；当然根据上述的配置参数还可以有更多的组合这里不再赘述。
针对步骤101由于无线接入网设备获取配置信息的具体方式可以为：无线接入网设备接收核心网设备发送的为终端设备配置的配置信息；或者，无线接入网设备接收终端设备发送的所述配置信息，其中配置信息由核心网设备发向终端设备。即，核心网设备可以在向终端设备配置tx profile的同时，向无线接入网设备发送该tx profile；或者核心网设备向终端设备配置tx profile后，由终端设备向无线接入网设备转发该tx profile。其中图7中仅示出了终端设备向无线接入网设备发送配置信息的过程。
102、无线接入网设备根据配置信息生成生成指示信息，并将生成指示信息发向终端设备。
在步骤101中由于无线接入网设备获取了配置信息，因此当为终端设备配置指示 信息时，无线接入网设备需要考虑核心网设备为终端设备配置的tx profile。此时无线接入网设备根据配置信息生成指示信息。示例性的该指示信息可以为重写的tx profile，如：无线接入网设备在核心网设备配置的tx profile限制的范围内重新选择的配置参数；或者，指示信息直接携带终端设备传输V2X业务的数据使用的资源配置，资源配置为无线接入网设备直接根据核心网设备配置的tx profile中的一个或多个配置参数生成。另外，指示信息也可以为无线接入网设备不考虑核心网设备为终端设备配置的tx profile直接重写的tx profile。
其中，依据配置信息包含的配置参数所包含备选参数，步骤102中，无线接入网设备具体可以采用如下不同方式生成指示信息：
方式一：配置信息包含的任一项配置参数包含一个备选参数时；无线接入网设备可以直接根据备选参数为终端设备配置资源，并将备选参数对应的资源配置携带在指示信息中发向终端设备。例如：如果V2X业务的tx profile为LTE V2X，则为终端设备的V2X业务生成LTE V2X sidelink的资源配置，示例性的，LTE V2X sidelink资源配置可以包括LTE V2X sidelink的发送资源池和/或接收资源池等；如果V2X业务的tx profile为NR V2X，则为终端设备的V2X业务生成NR V2X sidelink的资源配置，示例性的，NR V2X sidelink资源配置可以包括NR V2X sidelink的发送资源池、接收资源池等。最终，在步骤103中，终端设备根据指示信息指示的资源配置进行V2X业务通信。
方式二：配置信息包含的任一项配置参数包含至少两个备选参数时；具体参照以下示例进行说明：
示例一，配置信息包含的任一项配置参数包含至少两个备选参数时；例如：V2X业务的tx profile为LTE V2X或NR V2X。则可以由无线接入网设备在至少两个备选参数中确定目标备选参数，例如：由无线接入网设备为终端设备确定传输V2X业务的数据使用LTE V2X还是使用NR V2X，并且无线接入网设备将目标备选参数对应的资源配置携带在指示信息中发向终端设备，例如，无线接入网设备确定终端设备传输V2X业务的数据使用LTE V2X时，为终端设备的V2X业务生成LTE V2X的资源配置。最终，终端设备根据指示信息指示的资源配置传输V2X业务的数据。
示例二：配置信息包含的任一项配置参数包含至少两个备选参数时；例如：NR V2X的模式为mode1或mode2。则可以由无线接入网设备在至少两个备选参数中确定目标备选参数，例如：无线接入网设备确定终端设备传输V2X业务的数据使用NR V2X mode2时，且无线接入网设备将NR V2X mode2携带在指示信息中发向终端设备，最终，终端设备根据指示信息指示的NR V2X mode2传输V2X业务的数据。
示例三，由无线接入网设备定义一套规则配给终端设备，让终端设备依据规则选择，例如：指示信息用于指示备选参数选择规则，则在步骤103中终端设备可以根据备选参数选择规则在至少两个备选参数中选择目标备选参数；并最终，使用目标备选参数传输V2X业务的数据。例如，备选参数选择规则可以为当终端设备测量到LTE V2X sidelink的CBR大于或大于等于门限值，和/或，NR V2X sidelink的CBR小于或小于门限值，则选择NR V2X进行传输；当LTE V2X sidelink的CBR小于或小于等于门限值，和/或，NR V2X sidelink的CBR大于或大于门限值，则选择LTE V2X进行传 输。最终，终端设备根据确定的备选参数向无线接入网设备请求传输V2X业务的数据的资源。示例性的，终端设备选择使用的备选参数后，向无线接入网设备请求资源配置，并通过无线接入网设备发送的资源配置传输V2X业务的数据。例如，终端设备选择使用的技术类别，可以参照如下方式实现：终端设备直接选择，或者终端设备基于对V2X sidelink的测量结果进行选择，测量可以是测V2X sidelink的CBR(channel bussy ratio，信道繁忙率)，例如终端设备选择一个CBR测量结果更好的V2X sidelink进行传输，或者，终端设备选择一个当前可用的V2X进行传输，例如当前只有NR V2X资源可用，则采用NR V2X进行传输。其中，V2X业务可以通过destination ID(目标标识)来表示，也可以通过服务提供商标识(provider service identifier，PSID)或智能运输系统应用标识符(intelligent transport systems application identifier；ITS-AID)表示。tx profile可以用tx profile ID来表示，则要求协议定义好一套tx profile，所有的网元都能够知道每个tx profile ID对应的意思，或者tx profile也可以采用显性方式指示。
针对上述终端设备基于测量选择备选参数的场景，此时可以由无线接入网设备广播或通过RRC信令向终端设备发送一套门限值，以CBR测量为例，该门限值可以是LTE V2X SL CBR门限值，或者，NR V2X SL CBR门限值，或者，LTE V2X SL CBR门限值和NR V2X SL CBR门限值。以无线接入网设备为终端设备配置LTE V2X SL CBR门限值为例，如果终端设备测量到LTE V2X SL CBR结果小于或小于等于所述LTE V2X SL CBR门限值，则选择LTE V2X SL进行V2X业务数据的传输；以无线接入网设备为终端设备配置NR V2X SL CBR门限值为例，如果终端设备测量到NR V2X SL CBR结果小于或小于等于所述NR V2X SL CBR门限值，则选择NR V2X SL进行V2X业务数据的传输；以无线接入网设备为终端设备配置LTE V2X SL CBR门限值和NR V2X SL CBR门限值为例，如果终端设备测量到LTE V2X SL CBR结果小于或小于等于所述LTE V2X SL CBR门限值,且NR V2X SL CBR结果大于或大于等于NR V2X SL CBR门限值，则选择LTE V2X SL进行V2X业务数据的传输，如果终端设备测量到LTE V2X SL CBR结果大于或大于等于所述LTE V2X SL CBR门限值,且NR V2X SL CBR结果小于或小于等于NR V2X SL CBR门限值，则选择NR V2X SL进行V2X业务数据的传输。
需要说明的是，上述示例三中门限值仅以CBR测量结果为例进行说明，可以理解的是示例三示出的方案的门限值也可以是基于其他的测量结果，例如基于V2X sidelink上的参考信号进行测量得到的测量结果。
示例四，配置信息包含的任一项配置参数包含至少两个备选参数时；例如：V2X业务的tx profile为LTE V2X或NR V2X。无线接入网设备还可以通过指示信息指示终端设备将一个V2X业务中的部分数据通过LTE V2X进行传输，另外部分数据通过NR V2X进行传输。示例性的，无线接入网设备确定一个V2X业务的不同QoS要求的数据使用的备选参数；无线接入网设备将一个V2X业务的不同QoS要求的数据使用的备选参数所对应的资源配置携带在指示信息中发向终端设备，即，将一个V2X业务中QoS参数与备选参数的对应关系作为指示信息发送给终端设备。最终，终端设备根据指示信息指示的资源配置传输V2X业务的数据。这样，可以将一个V2X业务中的不同QoS要求的数据配置到不同的V2X路径上进行传输，QoS可以是PPPP(ProSe  per-packet priority，近距离通信数据包优先级)、近距离通信数据包可靠性(prose per packet reliability，PPPR)、QoS流标识(QoS flow identity，QFI)、5G QoS指示(5G QoS Identifier，5QI)或其他的任意一种或组合。此时无线接入网设备针对V2X业务配置QoS参数和V2X路径的对应关系，即V2X业务的某些QoS的数据通过LTE V2X进行传输，某些QoS的数据通过NR V2X进行传输。
另外，对配置信息包含的配置参数具体说明如下：
核心网设备配置的tx profile限定终端设备在侧行链路上传输业务数据使用的技术类别时，则tx profile的具体形式可以包括以下几类：
LTE V2X；
NR V2X；
LTE V2X和/或NR V2X。
[根据细则91更正 23.10.2019]　
当终端设备有一个V2X业务的数据要传输时，如果tx profile指示终端设备采用LTE V2X进行V2X业务数据的传输，则无线接入网设备根据tx profile生成指示信息发送给终端设备，指示信息包括LTE V2X的资源配置，终端设备可以根据无线接入网设备生成的指示信息采用LTE V2X进行业务数据的传输；如果tx profile指示终端设备采用NR V2X进行所述V2X业务数据的传输，则无线接入网设备根据tx profile生成指示信息发送给终端设备，指示信息包括NR V2X的资源配置，终端设备可以根据无线接入网设备生成的指示信息采用NR V2X进行业务数据传输；如果tx profile指示终端设备采用LTE V2X和/或NR V2X进行V2X业务数据的传输，即LTE V2X或NR V2X都可以，则无线接入网设备根据tx profile生成指示信息发送给终端设备，参照上述方式一、二所述，传输指示信息可以包含LTE V2X对应的资源配置和/或NR V2X对应的资源配置,终端设备直接按照无线接入网设备发送的资源配置进行业务数据传输；或者，传输指示信息可以包含指示备选参数选择规则，相应的，终端设备根据备选参数选择规则自行选择LTE V2X和/或NR V2X进行业务数据传输。当然，终端设备根据传输指示信息进行业务数据传输的具体实施方式可以直接援引上述方式一或方式二的描述，此处不再赘述。当然，可以在配置信息中定义tx profile指示所有的V2X技术类别，也可以通过在配置信息中不发送tx profile的方式隐性的指示所有的V2X技术类别。
核心网设备配置的tx profile限定终端设备在侧行链路上传输业务数据使用的空中接口时，则tx profile的具体形式可以包括以下几类：
LTE Uu；
NR Uu；
LTE Uu和/或NR Uu。
当tx profile限定空中接口时，当终端设备有一个V2X业务的数据要传时，如果tx profile指示终端设备采用LTE Uu进行V2X业务数据的传输，则无线接入网设备根据tx profile生成指示信息，指示信息包括LTE Uu的资源配置，终端设备可以根据无线接入网设备生成的指示信息采用LTE Uu进行业务数据的传输；如果tx profile指示终端设备采用NR Uu进行所述V2X业务数据的传输，则无线接入网设备根据tx profile生成指示信息发送给终端设备，指示信息包括NR Uu的资源配置，则终端设备可以根 据无线接入网设备生成的指示信息采用NR Uu进行业务数据传输；如果tx profile指示的是LTE Uu和/或NR Uu进行V2X业务数据的传输，即LTE Uu和/或NR Uu都可以，则无线接入网设备根据tx profile生成指示信息发送给终端设备，参照上述方式一、二所述，传输指示信息可以包含LTE Uu和/或NR Uu对应的资源配置，终端设备直接按照无线接入网设备发送的资源配置进行业务数据传输；或者，传输指示信息可以包含指示备选参数选择规则，相应的，终端设备根据备选参数选择规则自行选择LTE Uu和/或NR Uu进行业务数据传输。例如，由于LTE Uu和NR Uu够支持的V2X业务类型也有可能不一样，因此终端设备可以根据根据V2X业务类型自行选择采用LTE Uu或者NR Uu。或者，终端设备可以根据Uu的测量结果来选择LTE Uu或NR Uu，相应的，需要无线接入网设备为终端设备配置LTE Uu测量门限值和/或NR Uu测量门限值，测量结果可以是参考信号接收功率(Reference Signal Received Power，RSRP)或参考信号接收质量(Reference Signal Received Quality，RSRQ)。示例性的，无线接入网设备为终端设备配置LTE Uu的RSRP门限值，当终端设备测量到LTE Uu的RSRP大于或者大于等于LTE Uu的RSRP门限值，则选择LTE Uu进行数据传输，否则选择NR Uu进行数据传输；无线接入网设备为终端设备配置NR Uu的RSRP门限值，当终端设备测量到NR Uu的RSRP大于或者大于等于NR Uu的RSRP门限值，则选择NR Uu进行数据传输，否则选择LTE Uu进行数据传输；无线接入网设备为终端设备配置LTE Uu的RSRP门限值和NR Uu的RSRP门限值，当终端设备测量到LTE Uu的RSRP小于或者小于等于LTE Uu的RSRP门限值，且终端设备测量到NR Uu的RSRP大于或者大于等于RSRP门限值，则选择NR Uu进行数据传输；无线接入网设备为终端设备配置LTE Uu的RSRP门限值和NR Uu的RSRP门限值，当终端设备测量到LTE Uu的RSRP大于或者大于等于LTE Uu的RSRP门限值，且终端设备测量到NR Uu的RSRP小于或者小于等于RSRP门限值，则选择LTE Uu进行数据传输。当然，终端设备和无线接入网设备选择相应的空中接口的具体实施方式参见上述方式一或方式二，此处不再赘述。
核心网设备配置的tx profile限定终端设备在侧行链路上传输业务数据使用的模式，则tx profile的具体形式可以包括以下几类：
LTE V2X mode3；
LTE V2X mode4；
NR V2X mode1；
NR V2X mode2；
LTE V2X mode3和/或NR V2X mode1；
LTE V2X mode4和/或NR V2X mode2。
类似的，当tx profile限定终端设备在侧行链路上传输业务数据使用的模式时，当终端设备有一个V2X业务的数据要传时，如果tx profile指示终端设备采用LTE V2X mode3进行V2X业务数据的传输,则无线接入网设备根据tx profile生成指示信息发送给终端设备，指示信息包括LTE V2X mode3的资源配置，终端设备可以根据无线接入网设备生成的指示信息采用LTE V2X mode3进行业务数据的传输；如果tx profile指示终端设备采用LTE V2X mode4进行V2X业务数据的传输，则无线接入网设备根据 tx profile生成指示信息发送给终端设备，指示信息包括LTE V2X mode4的资源配置，则终端设备可以根据无线接入网设备生成的指示信息采用LTE V2X mode4进行业务数据传输；如果tx profile指示终端设备采用NR V2X mode1进行V2X业务数据的传输，则无线接入网设备根据tx profile生成指示信息发送给终端设备，指示信息包括NR V2X mode1的资源配置,终端设备可以根据无线接入网设备生成的指示信息采用NR V2X mode1进行业务数据传输；如果tx profile指示终端设备采用NR V2X mode2进行V2X业务数据的传输，则无线接入网设备根据tx profile生成指示信息发送给终端设备，指示信息包括NR V2X mode2的资源配置,终端设备可以根据无线接入网设备生成的指示信息采用NR V2X mode2进行业务数据传输；如果tx profile指示终端设备采用LTE V2X mode3和/或NR V2X mode1进行V2X业务数据的传输；即LTE V2X mode3和/或NR V2X mode1都可以，则无线接入网设备根据tx profile生成指示信息，参照上述方式一、二所述，传输指示信息可以包含LTE V2X mode3和/或NR V2X mode1对应的资源配置,终端设备直接按照无线接入网设备发送的资源配置进行业务数据传输；或者，传输指示信息可以包含指示备选参数选择规则，相应的，终端设备根据备选参数选择规则自行选择LTE V2X mode3和/或NR V2X mode1进行业务数据传输；当然，tx profile还可以同时指示LTE V2X mode3、NR V2X mode1、LTE V2X mode4以及NR V2X mode2。当然，终端设备和无线接入网设备选择相应的V2X的模式的具体实施方式参见上述方式一或方式二，此处不再赘述。
此外，核心网设备配置的tx profile只限定终端设备在侧行链路上传输业务数据使用的RAT(radio access technology，无线接入技术)，例如tx profile包括：
LTE；
NR；
LTE和/或NR。
当tx profile限定RAT时，当终端设备有一个V2X业务的数据要传时，如果tx profile指示终端设备采用LTE进行V2X业务数据的传输，则无线接入网设备根据tx profile生成指示信息发送给终端设备，指示信息包括LTE的资源配置，则终端设备根据无线接入网设备生成的指示信息采用LTE进行业务数据的传输；如果tx profile指示终端设备采用NR进行V2X业务数据的传输，则无线接入网设备根据tx profile生成指示信息发送给终端设备，指示信息包括NR的资源配置，终端设备根据无线接入网设备生成的指示信息采用NR进行业务数据传输；如果tx profile指示终端设备采用LTE和/或NR都可以，则无线接入网设备根据tx profile生成指示信息，参照上述方式一、二所述，传输指示信息可以包含LTE和/或NR对应的资源配置,终端设备直接按照无线接入网设备发送的资源配置进行业务数据传输；或者，传输指示信息可以包含指示备选参数选择规则，相应的，终端设备根据备选参数选择规则自行选择LTE和/或NR进行业务数据传输。则终端设备可以自行选择LTE或NR进行业务数据传输。当然，终端设备选择相应的RAT的具体实施方式参见上述方式一或方式二，此处不再赘述。在RAT下到底是通过V2X sidelink传输还是通过Uu传输，由无线接入网设备决定。可选的，是用mode1还是用mode2，也由无线接入网设备定。
可以理解的是，tx profile还可以是终端设备在侧行链路上传输业务数据使用的技 术类别、终端设备在侧行链路上传输业务数据使用的空中接口、终端设备在侧行链路上传输业务数据使用的无线接入技术以及终端设备在侧行链路上传输业务数据使用的模式中的一项或多项形成的组合，例如组合1为采用的技术类别为R16NR V2X时采用的模式为mode1；组合2为采用技术类别为R15LTE V2X时采用的模式为mode4，等等。
103、终端设备接收无线接入网设备发送的指示信息，根据指示信息在侧行链路上传输业务数据。
示例性的，指示信息可以包括终端设备在侧行链路上传输业务数据使用的资源配置，这样，步骤103具体为：终端设备根据资源配置在侧行链路上传输业务数据。
例如，配置信息包含的任一项配置参数包含一个备选参数时；无线接入网设备可以直接根据备选参数为终端设备配置资源。这样，无线接入网设备可以将备选参数对应的资源配置携带在指示信息中发向终端设备。例如：如果V2X业务的tx profile为LTE V2X，则为终端设备的V2X业务生成LTE V2X sidelink的资源配置，示例性的，LTE V2X sidelink资源配置可以包括LTE V2X sidelink的发送资源池、接收资源池等；如果V2X业务的tx profile为NR V2X，则为终端设备的V2X业务生成NR V2X sidelink的资源配置，示例性的，NR V2X sidelink资源配置可以包括NR V2X sidelink的发送资源池、接收资源池等。最终，终端设备根据指示信息指示的资源配置进行V2X业务通信。
另外，配置信息包含的任一项配置参数包含至少两个备选参数时；无线接入网设备可以确定每部分数据使用的备选参数；无线接入网设备将每部分数据使用的备选参数所对应的资源配置携带在指示信息中发向终端设备。例如，无线接入网设备还可以通过指示信息指示终端设备将V2X业务中的部分数据通过LTE V2X进行传输，另外部分数据通过NR V2X进行传输。最终，终端设备根据指示信息指示的资源配置在侧行链路上传输业务数据。
另外，配置信息包含的任一项配置参数包含至少两个备选参数时；可以由无线接入网设备在至少两个备选参数中确定目标备选参数，并且无线接入网设备将目标备选参数对应的资源配置携带在指示信息中发向终端设备。例如，V2X业务的tx profile为LTE V2X或NR V2X，由无线接入网设备为终端设备确定传输V2X业务的数据使用LTE V2X还是使用NR V2X，无线接入网设备确定终端设备传输V2X业务的数据使用LTE V2X时，为终端设备的V2X业务生成LTE V2X的资源配置。最终，终端设备根据指示信息指示的资源配置在侧行链路上传输业务数据。
示例性的，指示信息可以包含无线接入网设备在至少两个备选参数中确定的目标备选参数；这样，步骤103具体为：终端设备使用目标备选参数在侧行链路上传输业务数据。
例如：配置信息包含的任一项配置参数包含至少两个备选参数时，可以由无线接入网设备在至少两个备选参数中确定目标备选参数，并且无线接入网设备将目标备选参数携带在指示信息中发向终端设备；示例性的，NR V2X的模式为mode1或mode2。则无线接入网设备确定终端设备传输V2X业务的数据使用NR V2X mode2时，且无线接入网设备将NR V2X mode2携带在指示信息中发向终端设备，最终，终端设备根据 指示信息指示的NR V2X mode2传输V2X业务的数据。
示例性的，指示信息用于指示备选参数选择规则，这样，步骤103具体为：终端设备根据备选参数选择规则在至少两个备选参数中选择目标备选参数；终端设备使用目标备选参数在侧行链路上传输业务数据。
例如：备选参数选择规则可以为当终端设备测量到LTE V2X sidelink的CBR大于或大于等于门限值，和/或，NR V2X sidelink的CBR小于或小于门限值，则选择NR V2X进行传输；当LTE V2X sidelink的CBR小于或小于等于门限值，和/或，NR V2X sidelink的CBR大于或大于门限值，则选择LTE V2X进行传输。最终，终端设备根据确定的备选参数向无线接入网设备请求传输V2X业务的数据的资源。示例性的，终端设备选择使用的备选参数后，向无线接入网设备请求资源配置，并通过无线接入网设备发送的资源配置传输V2X业务的数据。例如，终端设备选择使用的V2X技术类别，可以参照如下方式实现：终端设备直接选择，或者终端设备基于对V2X sidelink的测量结果进行选择，测量可以是测V2X sidelink的CBR(channel bussy ratio，信道繁忙率)，例如终端设备选择一个CBR测量结果更好的V2X sidelink进行传输，或者，终端设备选择一个当前可用的V2X进行传输，例如当前只有NR V2X资源可用，则采用NR V2X进行传输。针对上述终端设备基于测量选择备选参数的场景，此时可以由无线接入网设备广播或通过RRC信令向终端设备发送一套门限值，以CBR测量为例，该门限值可以是LTE V2X SL CBR门限值，或者，NR V2X SL CBR门限值，或者，LTE V2X SL CBR门限值和NR V2X SL CBR门限值。以无线接入网设备为终端设备配置LTE V2X SL CBR门限值为例，如果终端设备测量到LTE V2X SL CBR结果小于或小于等于所述LTE V2X SL CBR门限值，则选择LTE V2X SL进行V2X业务数据的传输；以无线接入网设备为终端设备配置NR V2X SL CBR门限值为例，如果终端设备测量到NR V2X SL CBR结果小于或小于等于所述NR V2X SL CBR门限值，则选择NR V2X SL进行V2X业务数据的传输；以无线接入网设备为终端设备配置LTE V2X SL CBR门限值和NR V2X SL CBR门限值为例，如果终端设备测量到LTE V2X SL CBR结果小于或小于等于所述LTE V2X SL CBR门限值,且NR V2X SL CBR结果大于或大于等于NR V2X SL CBR门限值，则选择LTE V2X SL进行V2X业务数据的传输，如果终端设备测量到LTE V2X SL CBR结果大于或大于等于所述LTE V2X SL CBR门限值,且NR V2X SL CBR结果小于或小于等于NR V2X SL CBR门限值，则选择NR V2X SL进行V2X业务数据的传输。
考虑可能的DC(dual connectivity，双连接)和切换场景，需要在无线接入网设备间交互配置信息，具体包括：DC场景中，主无线接入网设备将tx profile发送给辅无线接入网设备；切换场景中，源无线接入网设备将tx profile发送给目标无线接入网设备。
这样，无线接入网设备获取配置信息，该配置信息用于终端设备在侧行链路上传输业务数据，配置信息包括以下各项配置参数中的任一项或任几项：终端设备在侧行链路上传输业务数据使用的技术类别、终端设备在侧行链路上传输业务数据使用的空中接口、终端设备在侧行链路上传输业务数据使用的无线接入技术以及终端设备在侧行链路上传输业务数据使用的模式；其中，侧行链路为终端设备和另一个终端设备之 间的无线通信链路；无线接入网设备根据所述配置信息生成指示信息，无线接入网设备将指示信息发向终端设备，以指示终端设备根据指示信息在侧行链路上传输业务数据。这样，现有技术中核心网设备为终端设备静态配置tx profile，而本申请中首先由无线接入网设备获取终端设备在侧行链路上传输业务数据使用的配置信息，例如，该配置信息可以为核心网设备为终端设备配置的或者无线接入网设备根据终端设备的请求为终端设备配置的，由于无线接入网设备可以感知侧行链路实时的状态，因此可以根据配置信息向终端设备发送指示信息时，可以结合侧行链路实时的状态，这样终端设备根据指示信息在侧行链路上传输业务数据，可以提高业务的传输质量。
基于图7所述的方法，核心网设备在为终端设备的V2X业务配置tx profile之前，必须知道终端设备支持的V2X能力。例如终端设备是否支持LTE V2X和NR V2X，这是终端设备的无线能力，按照现有技术，核心网设备是无法解析终端设备的无线能力的。因此，需要终端设备向核心网设备上报终端设备支持的V2X能力，以便于核心网设备根据终端设备支持的V2X能力生成配置信息。示例性的，终端设备支持的V2X能力可以有多个维度，例如：终端设备支持的V2X能力包括终端设备支持的技术类别，示例性的，技术类别可以包含LTE V2X、NR V2X；可选的，技术类别可以包含V2X技术具体的版本信息，例如：R14 LTE V2X、R15 LTE V2X、R16 NR V2X、以及可能的后续演进版本，如R16 LTE V2X、R17 NR V2X等。终端设备支持的V2X能力包括终端设备支持的V2X技术的特性，终端设备支持的V2X技术的特性包括以下各项中的一项或多项：V2X技术支持的调制技术、编码技术、加密技术、CA(carrier aggregation，载波聚合)以及DC。如果终端设备上报的是终端设备支持的V2X技术支持的特性，则相应的V2X的tx profile可以包括V2X业务需要采用的V2X特性，例如某些V2X业务要求以特定的调制解调技术进行传输，某些V2X业务要求以特定的加密技术进行加密、传输。
为了能够让核心网设备知道终端设备支持的V2X能力，可选的有以下几种方式：
终端设备通过NAS(Non-access stratum，非接入层)消息通知核心网设备的控制网元；终端设备通过与control function之间接口告知control function；终端设备将终端设备支持的V2X能力上报给无线接入网设备之后，无线接入网设备将终端设备上报的终端设备支持的V2X能力发向所述核心网设备，例如无线接入网设备可以通过无线接入网设备与核心网设备之间的接口将终端设备支持的V2X能力告知核心网设备。
除此之外，无线接入网设备获取终端设备的配置信息之前，核心网设备也需要知道无线接入网设备支持的V2X能力，比如，可以是无线接入网设备支持的技术类别，示例性的，V2X技术类别可以包含LTE V2X、NR V2X；可选的，技术类别可以包含V2X技术具体的版本信息，例如：R14 LTE V2X、R15 LTE V2X、R16 NR V2X、以及可能的后续演进版本，如R16 LTE V2X、R17 NR V2X等。即无线接入网设备需要向核心网设备上报支持的V2X能力。这样，避免核心网设备为终端设备配置无线接入网设备不支持的tx profile。这样，核心网设备根据无线接入网设备支持的V2X能力和/或终端设备支持的V2X能力生成配置信息。
另外，考虑核心网设备可能会无法覆盖所有可能的V2X业务，即可能存在一个V2X业务是核心网设备没有配置tx profile的。如果，终端设备发起了一个未配置过 tx profile的V2X业务，则终端设备需要将V2X业务信息告知无线接入网设备或者核心网设备，请求无线接入网设备或者核心网设备为V2X业务分配tx profile。参照图8所示，具体采用如下步骤实现数据的传输：
201、无线接入网设备接收终端设备发送的业务配置请求信息，业务配置请求信息用于指示业务信息。
业务信息可以包括业务类型、QoS要求等。业务类型可以是上述方案提到的destination ID、PSID、ITS-AID；或者是V2I、V2P、V2N或者V2V；或者是广播业务、组播业务或者单播业务。QoS要求可以是一个或多个QoS参数，QoS参数可以是PPPP、PPPR、QFI、5QI或者其他。
202、无线接入网设备根据业务配置请求信息生成配置信息。
203、无线接入网设备根据配置信息生成指示信息，并将指示信息发向终端设备。
204、终端设备接收无线接入网设备发送的指示信息。
205、终端设备根据指示信息在侧行链路上传输业务数据。
其中，在该方案中步骤203-205中可以是无线接入网设备直接根据配置信息通过指示信息为终端设备发送资源配置，例如上述的方式一，或者方式二的示例一；或者将配置信息直接发向终端设备，由终端设备根据无线接入网设备配置的规则选择配置参数，如上述的方式二中的示例二；此处不再赘述。
当然，终端设备也可以将业务配置请求信息上报给核心网设备，由核心网设备为终端设备配置配置信息。
