Description

一种数据传输方法及装置、计算机存储介质 技术领域

在第三代合作伙伴项目(3GPP,the 3rd Generation Partnership Project)Rel-14中对车联网技术(V2X,Vehicle-to-Everything)进行了标准化,定义了两种传输模式:模式3和模式4。在模式3中,终端的传输资源由基站分配。在模式4中,终端采用侦听(sensing)+预留(reservation)的方式确定传输资源。
在Rel-15中,演进的车联网技术(eV2X,evolved Vehicle-to-Everything)拓展到了多载波场景,即一个用户设备(UE,User Equipment)可以同时在多于一个载波上传输信号,这带来的一个问题就是如何进行载波的选择。

具体实施方式
为便于理解本发明实施例的技术方案,以下分别对车联网中的模式3和模式4进行解释说明。
模式3:如图1所示,车载终端的传输资源是由基站(如LTE中的演进基站(eNB,evolved NodeB))分配的,具体地,基站通过下行链路(DL,Down Link)向车载终端下发用于指示授权(Grant)资源的控制消息;而后,车载终端根据基站分配的资源在SL上进行数据的发送。在模式3中,基站可以为车载终端分配单次传输的资源,也可以为终端分配半静态传输的资源。
模式4:如图2所示,车载终端采用侦听+预留的传输方式。车载终端在资源池中通过侦听的方式获取可用的传输资源集合,车载终端从该传输资源集合中随机选取一个 资源进行数据的传输。由于车联网系统中的业务具有周期性特征,因此车载终端通常采用半静态传输的方式,即车载终端选取一个传输资源后,就会在多个传输周期中持续的使用该资源,从而降低资源重选以及资源冲突的概率。车载终端会在本次传输的控制信息中携带预留下次传输资源的信息,从而使得其他终端可以通过检测该车载终端的控制信息判断这块资源是否被该车载终端预留和使用,达到降低资源冲突的目的。
需要说明的是,在LTE-V2X中分别使用模式3表示车载终端的传输资源是由基站分配的,用模式4表示车载终端的传输资源是终端自主选取的,本发明实施例的技术方案解决模式4下的载波选取问题。在新无线-车联网技术(NR-V2X,New Radio-Vehicle-to-Everything)中,可以定义新的传输模式,本发明对此不做限定。
载波的选择需要考虑发送机的射频能力。例如,若选择了载波1和载波2进行信号的发送,则在载波1和载波2上选取的时频资源需要满足如下要求:
1)若载波1和载波2上选取的时频资源如果在时间上位置相同,则要求终端具有在多个载波上同时发送的能力(即终端支持多载波发送能力),并且所述多载波发送能力支持载波1和载波2的频带组合;
2)若载波1和载波2上选取的时频资源如果在时间上位置不同,则终端可以通过单载波发送机在不同载波上进行切换来支持载波1和2的发送,但这要求载波1和载波2上选取的时频资源在时间上的间隔足够长,以满足用户在不同载波上的切换时延要求。
上述的要求表明,终端在多个载波上的资源选择是互斥的,按照什么原则进行载波的选择是本发明实施例能够解决的问题。
本发明实施例的全部技术方案,不仅适用于车联网系统中,也可以适用于其他端到端通信系统中,本发明实施例中的所述终端可以为车载终端、手持终端、掌上电脑(PDA,Personal Digital Assistant)、可穿戴式终端等等,本发明实施例中的所述网络可以为NR网络、LTE网络等等。
图3为本发明实施例的数据传输方法的流程示意图一,如图3所示,所述数据传输方法包括以下步骤:
步骤301:终端确定第一载波集合上的所有载波的CBR测量值均高于门限值时,在所述第一载波集合中确定目标载波并利用所述目标载波传输目标数据,或者,不在任何载波上传输所述目标数据;其中,所述第一载波集合为所述目标数据所属的目标业务对应的载波集合。
本发明实施例中,所述终端可以是手机、平板电脑、笔记本、台式机、车载终端、可穿戴式终端等任意类型的终端。
本发明实施例中,所述第一载波集合为所述目标数据所属的目标业务对应的载波集合,例如目标数据所属的目标业务为A业务,那么A业务所映射到的载波集合就是第一载波集合。

本发明实施例中,如果一个载波的CBR测量值高于对应的门限值,则该载波不可以用于传输目标数据,如果一个载波的CBR测量值低于对应的门限值,则该载波可以用于传输目标数据。当终端确定第一载波集合上的至少一个载波的CBR测量值低于门限值时,在所述至少一个载波中确定目标载波并利用所述目标载波传输目标数据。
在一实施方式中,所述终端基于接入层的第一配置信息,确定所述第一载波集合上的至少一个载波的门限值为最大CBR值,并确定所述至少一个载波的CBR测量值低于门限值。例如:接入层配置至少一个载波的CBR门限值为最大值(即100%),则所述至少一个载波的CBR测量值肯定低于配置的门限值(即100%),所述至少一个载波可以用于传输目标数据,终端可以在这些可以用于传输目标数据的载波中选择一个载波来传输目标数据。
例如:第一载波集合包括载波1、载波2、载波3、载波4,其中,载波1和载波3的CBR门限值为100%,由于载波1和载波3的CBR测量值的范围为0%到100%,因此,载波1和载波3的CBR测量值肯定低于相应的门限值,终端可以在载波1和载波3中选择一个载波来传输目标数据。
