可选地，第一业务类型类型可以为按照需求划分的业务类型，例如按道路安全需求划分为安全类和非安全类业务。假设第一业务类型为安全相关类的车联网业务类型，那么按照业务类型为安全相关类的车联网业务配置第一业务类型的传输载频配置信息，第一业务类型的传输载频配置信息可以包括至少一个第一传输载频标识，该第一传输载频标识与传输安全相关类的车联网业务的传输载频对应。上述描述对于第一业务类型为非安全类业务类型同样适用，其中第一业务类型可以为非安全相关类的车联网业务类型。
可选地，第一传输载频标识与第一传输载频的关系是对应的。例如，第一传输载频标识与第一传输载频的对应关系可以是一对一，也可以是多对一。第一通信节点根据第一传输载频标识与第一传输载频的对应关系，通过第一传输载频传输第一业务类型的业务数据。
可选地，第一传输载频标识可以是频点指示或频点索引标识。
步骤220：第一通信节点获取第一业务数据和第一标识，第一标识用于指示第一业务数据属于第一业务类型。
在可选地实施例中，第一通信节点接收接入层之上的协议层向接入层递交的第一业务数据包时，也将用于指示第一业务数据的业务类型信息，即第一标识，传输给接入层。
具体地，接入层之上的协议层例如，可以为网络传输层，应用层，网络适配层等协议形式；也可以是指物理协议层或媒体接入控制协议层或无线链路传输协议层或分组数据汇聚协议层之上的协议层，在此不对具体实现形式做限定。

在可选的实施例中，第一标识可以通过业务类型标识、目标地址标识、源地址标识、优先级标识、载频指示标识或信道指示标识中的所属数据结构的固定指示域指示。
例如，以目标地址标识为例，目标地址标识占用字段为24个bit，可以通过该24个bit位中的1个bit或者多个bit指示第一标识。
步骤230：第一通信节点根据第一标识以及第一传输载频标识确定传输第一业务数据所采用的第一传输载频。
在可选地实施例中，第一业务类型的传输载频配置信息还包括与门限值；当第一标识大于或等于门限值时，根据门限值对应的第一传输载频标识确定传输第一业务数据所采用的第一传输载频；或者，当第一标识小于门限值时，根据门限值对应的第一传输载频标识确定传输第一业务数据所采用的第一传输载频。
在可选地实施例中，当第一通信节点根据所述第一标识确定所述第一业务数据的业务类型属于所述第一业务类型业务类型时，根据所述第一传输载频标识确定传输所述第一业务数据所采用的所述第一传输载频。
具体地，门限值的可根据第一业务类型业务类型的划分进行预先设置。
例如，业务分为了四个类型，每个类型对应一个标识，四个标识分别为1、2、3、4；假设，门限值设置为,第一传输载频标识与第一传输载频1对应；当标识大于或等于门限值 时，标识为3的业务类型、标识为4的业务类型可以在第一传输载频1上传输；当标识小于门限值时，标识为1的业务类型、标识为2的业务类型可以在第一传输载频1上传输。可选择的，第一标识取值可以根据使用需求量化。
在可选地实施例中，在步骤230之前，业务数据传输方法包括步骤2310：第一通信节点接收基站通过系统广播信息或RRC专用信令发送的传输载频列表信息，该传输载频列表信息包括至少一个第二传输载频标识；第一传输载频对应的第一传输载频标识为传输载频列表信息所包括的第二传输载频标识中的一个。
具体地，在步骤230之前，例如，在步骤210之前执行步骤2310；或者，在与步骤210同时执行步骤2310；或者在步骤210和步骤220之间执行步骤2310；或者，与步骤220同时执行步骤2310，步骤2310与步骤210和步骤220执行的先后顺序，对执行结果没有影响。因此，不对步骤2310执行的顺序进行限定。
进一步，第一通信节点接收基站通过系统广播信息，或RRC专用信令发送的传输载频列表信息，该传输载频列表信息包括至少一个第二传输载频标识。第一传输载频对应的第一传输载频标识为传输载频列表信息所包括的第二传输载频标识中的一个。
在可选的实施例中，第一业务类型的传输载频配置信息包括与至少一个第一传输载频标识对应的至少一个第二标识；当第一标识为第二标识时，第一通信节点根据第二标识对应的第一传输载频标识确定传输第一业务数据所采用的第一传输载频。
具体地，当第一标识为与第一传输载频标识对应的第二标识时，可以确定第一业务数据的业务类型与第一业务类型类型的相同，进一步的，由第一通信节点根据第一传输载频标识确定传输第一业务数据所采用的第一传输载频。
可选的，第一传输载频标识与第二标识的对应关系。例如，第一传输载频标识与第二标识的对应关系对应关系可以为一个第二标识对应多个第一传输载频标识，也可以是一个第二标识对应一个第一传输载频标识，还可以是多个第二标识对应一个第一传输载频标识。具体的对应关系不一一列举。
假设，一个第二标识对应一个第一传输载频标识，第一通信节点根据第一业务类型的传输载频配置第二标识对应的第一传输载频标识确定第一业务数据所采用的第一传输载频。
假设，一个第二标识对应多个第一传输载频标识，第一通信节点从第二标识对应的第一传输载频标识中选取一个第一传输载频标识，通过该传输载频标识对应的第一传输载频传输第一业务数据。
在可选的实施例中，当第一业务类型的传输载频配置信息包括一个第一传输载频标识时，第一通信节点根据第一标识及第一传输载频标识确定第一业务数据所采用的第一传输载频包括一个传输载频，第一通信节点通过该传输载频传输第一业务数据。
在可选的实施例中，当第一业务类型的传输载频配置信息包括至少两个第一传输载频标识时，第一通信节点根据第一标识及第一传输载频标识确定第一业务数据所采用的第一传输载频包括至少两个传输载频，从至少两个传输载频中选择一个传输载频传输第一业务数据。
从至少两个传输载频中选择择一个传输载频的方式，以下仅列举三种方式。
在可选的实施例中，第一通信节点可以随机从第一传输载频中选择一个载频作为传输 第一业务数据的传输载频。
在可选的实施例中，第一通信节点可以根据第一传输载频的负载程度选择一个载频作为传输第一业务数据的传输载频。
在可选的实施例中，第一通信节点可向基站请求分配一个载频作为传输第一业务数据的传输载频。
步骤240：第一通信节点在第一传输载频上传输第一业务数据。
可选地，第一通信节点通过第一传输载频传输第一业务数据的方法包括但不限于第一通信节点直连通信、基站中转通信。
此外，当第一标识指示的第一业务数据的业务类型不属于第一业务类型时，不通过第一传输载频传输与第一业务数据。
当不同的第一业务数据对应的传输载频不同时，不同的第一业务数据在接入层需要运行独立的传输机制。
例如，第一通信节点据据与第一业务数据包1一并由接入层之上的协议层递交给接入层的第一标识1，确定第一业务数据包1要在传输载频1上传输；而第一通信节点根据其第一标识2，确定第一业务数据包2要在传输载频2上传输。第一通信节点将第一业务数据包1和第一业务数据包2分别在传输载频1和传输载频2上获取独立的传输资源用于传输第一业务数据包1和第一业务数据包2。
在可选的实施例中，在接入层进行数据复用时，在相同传输载频上传输的第一业务数据可以封装在相同的媒体访问控制(Media Acce Control，MAC)层用户分组数据单元(MAC PDU)中。而对于需要在不同传输载频上传输的数据，不可以分装在相同的MAC PDU中。
具体的，在接入层进行数据复用，也就是把不同的第一业务数据放在相同的传输载频上传输，可以对这个第一业务数据封装在相同的MAC PDU中，缩短了传输第一业务数据的时间，同时避免了不是同一类型的第一业务数据在同一传输载频上传输，满足频谱的使用规则。
可选的，将第一业务数据封装在MAC PDU中的封装原则包括但不限于采用V2X、设备到设备(Device to Device，D2D)的封装机制，或蜂窝网中基于逻辑令牌桶的封装机制。
在本申请实施例中，通过上述示例，本发明实施例提供的业务数据传输方法中，第一业务类型的传输载频配置信息包括至少一个第一传输载频标识，从而可以使得第一通信节点通过获取的第一标识和第一传输载频标识，确定传输第一业务数据所采用的第一传输载频。
