车联网系统采用终端到终端直接通信的方式,具有更高的频谱效率以及更低的传输时延。在车联网系统中,通常考虑两种类型的终端,一种是车载终端(Vehicle User Equipment,VUE),另一种是手持终端(Pedestrian User Equipment,PUE)。
在车联网系统中,终端与终端之间的通信,可以基于各种无线通信系统,例如:长期演进(Long Term Evolution,LTE)系统等。在无线通信系统中,多载波技术已经被作为扩展系统带宽的方法。在多载波模式下,多个载波可服务于一个终端,每个载波也叫一个组成载波。
然而,现有技术中没有给出在车联网系统中如何在多个载波上进行终端到终端的数据传输。
发明内容
本发明的多个方面提供车联网中的数据传输方法及终端,用以在车联网系统中进行终端到终端的数据传输。

101、终端确定承载第一业务数据的至少一个第一载波。
其中,所述第一业务数据为车联网中所述终端到接收终端的数据。
102、所述终端向网络设备发送所述至少一个第一载波上承载的所述第一业务数据的数据量。
至此,实现了在车联网系统中终端到终端之间的数据传输。
本发明中,所涉及的终端,可以为车载终端,或者还可以为具有侦听能力的手持终端,本实施例对此不进行特别限定。
本发明中,所涉及的网络设备可以为LTE系统中的演进型基站(Evolved NodeB,eNB)等网元,本实施例对此不进行特别限定。

例如,假设101中终端确定了2个第一载波,第一载波1上承载第一业务数据的数据量A,第一载波2上没有承载第一业务数据的数据量,那么,终端向网络设备所发送的所述至少一个第一载波上承载的所述第一业务数据的数据量则可以是第一载波1上承载第一业务数据的数据量A,以及第一载波2上承载第一业务数据的数据量0。
可选地,在本实施例的一个可能的实现方式中,在102中,终端向网络设备所发送的所述至少一个第一载波上承载的所述第一业务数据的数据量,可以是所述至少一个第一载波中真正承载所述第一业务数据的第一载波上承载的所述第一业务数据的数据量。
