车联网系统是基于长期演进技术(Long Term Evolution，LTE)-设备到设备(Device to Device，D2D)的一种侧行链路(Sidelink，SL)传输技术，与传统的LTE系统中通信数据通过基站接收或者发送的方式不同，车联网系统采用用户设备(User Equipment，UE)到用户设备直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。
对于载波聚合(carrier aggregation，CA)，支持数据复制传输(data dupl ication)。数据复制传输是利用分组数据汇聚协议层(Packet Data Convergenc e Protocol，PDCP)或媒体访问控制层(Media Access Control，MAC)的复制数据功能，使复制的协议数据单元(Protocol Data，PDU)分别传输到两个无线链路控制层协议(Radio Link Control，RLC)实体(entity)，以保证复制的PDU能够在不同物理层聚合载波上传输，从而达到频率分集增益以提高数据传输可靠性。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
以下分别进行详细说明。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
下面结合附图对本申请的实施例进行描述。
在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)Rel-14中对车辆到车辆(Vehicle to Vehicle，V2X)进行了标准化，定义了两种传输模式：模式3和模式4。模式3的网络构架图如图1所示，在模式3下，用户设备(如车载终端)的传输资源是由网络设备分配的，用户设备根据网络设备分配的资源在侧行链路上进行数据的发送；网络设备可以为用户设备分配单次传输的资源，也可以为用户设备分配半静态传输的资源。模式4的网络构架图如图2所示，在模式4下，用户设备(如车载终端)采用侦听(sensing)+预留(reservation)的传输方式。用户设备在资源池中通过侦听的方式获取可用的传输资源集合，用户设备从该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，因此用户设备通常采用半静态传输的方式，即用户设备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。用户设备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，从而使得其他用户设备可以通过检测该用户设备的控制信息判断这块资源是否被该用户设备预留和使用，达到降低资源冲突的目的。
当采用由网络进行资源调度的模式时，在数据复制模式下，用户设备之间传输的复制数据需要复用到不同的载波上。可见，需要在网络设备给出授权资 源(grant)时，网络设备明确该授权资源会被用户设备用户服务哪个版本的数据，在用户设备收到授权资源时，用户设备明确网络设备期望该授权资源被用户设备用于服务哪个版本的数据。
为了解决上述问题，在本方案中，网络设备先配置一个控制信息，这个控制信息被定义是用于确定授权资源用于传输复制数据的版本，然后网络设备发送这个控制信息；当用户设备接收到这个控制信息时，用户设备可根据这个控制信息明确网络设备期望该授权资源被用户设备用于服务哪个版本的数据。
其中，用户设备是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的用户设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
其中，网络设备是指网络侧的节点设备，例如，网络设备可以是蜂窝网络中接入网侧的无线接入网(Radio Access Network，RAN)设备，所谓RAN设备即是一种将用户设备接入到无线网络的设备，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)、管理实体(Mobility Management Entity，MME)；再如，网络设备也可以是无线局域网(Wireless Local Area Network，WLAN)中的节点设备，例如接入控制器(access controller，AC)，网关，或WIFI接入点(Access Point，AP)等。
下面结合图1和图2所示的网络构架对本申请实施例提供的数据调度方法进行详细说明。
请参见图3，图3为本申请实施例提供的一种数据调度方法的流程示意图，该数据调度方法是针对Dupliction在MAC层的情况，比如，如图4所示，在MAC层将一个MAC PDU复制成MAC PDU version A和MAC PDU version B，MAC PDU version A在物理层载波(physical Carrier)1上传输，MAC PDU version B在physical Carrier 2上传输，physical Carrier 1不同于physical Carrier2，假设一个混合自动重传请求(Hybrid Automatic Repeat-reQuest，HARQ)实 体对应一个physical Carrier，这该方法包括以下步骤：
步骤301：网络设备配置控制信息，所述控制信息用于确定授权资源用于传输复制数据的版本。
其中，所述控制信息可以是侧行链路控制信息(Sidelink Control Informat ion，SCI)，或是其他链路控制信息，在此不作限定。
在一示例中，所述控制信息包括以下至少一种：授权资源的时频位置信息、指示信息、用户设备身份标识(ID)、HARQ进程ID、新数据指示等等。
其中，所述指示信息用于指示所述授权资源用于传输复制数据的版本。
进一步地，当所述控制信息是SCI时，所述指示信息是所述SCI中新增的第一比特信息。
举例来说，网络设备配置SCI时，在SCI中新增一个1bit的信息(即第一比特信息)，新增的1bit的信息用于指示所述授权资源用于传输复制数据的版本。例如，在MAC层将一个MAC PDU复制成MAC PDU version A和MAC PDU version B，如果网络设备希望所述授权资源用于传输version A版本的数据，那么网络设备将新增的1bit信息的值置为“0”，如果网络设备希望所述授权资源用于传输version B版本的数据，那么网络设备将新增的1bit信息的值置为“1”。
进一步地，当所述控制信息是SCI时，所述指示信息是利用所述SCI中的1个预留比特来定义的。
举例来说，网络设备配置SCI时，利用SCI中的1个预留比特来定义一个新的信息(即指示信息)，新定义的信息用于指示所述授权资源用于传输复制数据的版本。例如，在MAC层将一个MAC PDU复制成MAC PDU version A和MAC PDU version B，如果网络设备希望所述授权资源用于传输version A版本的数据，那么网络设备将新定义的信息比特的值置为“0”，如果网络设备希望所述授权资源用于传输version B版本的数据，那么网络设备将新定义的信息比特的值置为“1”。
其中，所述用户设备ID用于指示授权资源的目的用户设备。
进一步地，当所述控制信息是SCI时，所述用户设备ID是所述SCI中新增的第二比特信息。
举例来说，网络设备配置SCI时，在SCI中新增一个多bit(比如32bit)的信息(即第二比特信息)，新增的多bit的信息用于指示授权资源的目的用户设备。例如，当前有3个D2D用户设备，这3个用户设备例如是用户设备A、用户设备B和用户设备C，网络设备发送授权资源给用户设备A，如果网络设备期望这个授权资源的目的用户设备是用户设备B，那么网络设备将新增的多bit信息置为用户设备B的ID。
进一步地，当所述控制信息是SCI时，所述用户设备ID是利用所述SCI中的多个预留比特来定义的。
举例来说，网络设备配置SCI时，利用SCI中的多个预留比特来定义一个新的信息(即用户设备ID)，新定义的信息用于指示授权资源的目的用户设备。例如，当前有3个D2D用户设备，这3个用户设备例如是用户设备A、用户设备B和用户设备C，网络设备发送授权资源给用户设备A，如果网络设备期望这个授权资源的目的用户设备是用户设备B，那么网络设备将新定义的信息置为用户设备B的ID。
其中，用户设备ID可以表示一个用户设备的ID，也可以表示一组用户设备的ID，在此不作限定。
步骤302：所述网络设备发送所述控制信息。
其中，网络设备向用户设备发送控制信息可以是网络设备直接向用户设备发送，也可以是通过其他网络设备向用户设备发送，在此不作限定。
步骤303：所述用户设备根据所述控制信息确定授权资源用于传输复制数据的版本。
在一示例中，所述控制信息包括指示信息，所述指示信息用于指示所述授权资源用于传输复制数据的版本，所述用户设备根据所述控制信息确定授权资源用于传输复制数据的版本的具体实施方式有：
所述用户设备根据所述指示信息确定授权资源用于传输复制数据的版本。
举例来说，假设在MAC层将一个MAC PDU复制成MAC PDU version A和MAC PDU version B，控制信息是SCI，指示信息是SCI中新增的一个1bit的信息，当新增的1bit信息的值置为“0”时表示授权资源用于传输version A版本的数据，当新增的1bit信息的值置为“1”时表示授权资源用于传输version  B版本的数据。假如用户设备解析来自网络设备的SCI得到SCI中新增的1bit信息的值为0时，用户设备确定网络设备期望用户设备在授权资源上传输version A的数据。
在一示例中，所述方法还包括：
所述网络设备发送信令，所述信令携带载波与复制数据版本的映射关系，所述载波与复制数据版本的映射关系用于确定授权资源用于传输复制数据的版本；
所述用户设备接收来自所述网络设备的信令；
所述用户设备根据所述控制信息确定授权资源用于传输复制数据的版本的具体实施方式有：
所述用户设备根据所述载波与复制数据版本的映射关系确定授权资源用于传输复制数据的版本。
具体地，网络设备事先定义一个载波与复制数据版本的映射关系，然后网络设备将该映射关系通过信令发送给用户设备，后续网络设备给用户设备发送授权资源，用户设备可根据授权资源的时频位置确定授权资源对应哪个载波，最后用户设备再根据该映射关系确定网络设备期望用户设备在这个授权资源上传输哪个版本的数据。其中，假设在MAC层将一个MAC PDU复制成MAC PDU version A和MAC PDU version B，载波与复制数据版本的映射关系例如可以如表1所示。举例来说，假设载波与复制数据版本的映射关系如表1所示，网络设备给用户设备发送的授权资源对应载波2，那么用户设备根据表1可确定网络设备期望用户设备在授权资源上传输version A版本的数据。
表1
载波 数据版本
载波1～3 version A
载波4～6 version B
进一步地，所述信令包括无线资源控制(Radio Resource Contro，RRC)信令或系统信息。
具体地，由于RRC信令和系统信息在网络设备和用户设备建立连接时均 需要，网络设备通过RRC信令或通过系统信息配置载波与复制数据版本的映射关系，可降低信令的开销。
步骤304：用户设备接收来自网络设备的所述控制信息；所述用户设备在所述授权资源上传输所述版本对应的数据。
在一示例中，所述控制信息包括用户设备ID，所述用户设备ID用于指示授权资源的目的用户设备，所述用户设备在所述授权资源上传输所述版本对应的数据的具体实施方式有：
所述用户设备在所述授权资源上传输所述用户设备ID的所述版本对应的数据。
举例来说，假如当前有3个D2D用户设备，这3个用户设备例如是用户设备A、用户设备B和用户设备C，网络设备给用户设备A发送控制信息，用户设备A接收到控制信息后，用户设备A解析控制信息得到用户设备ID是用户设备B的ID，用户设备A即可知道授权资源的目的用户设备是用户设备B，那么用户设备A在授权资源上传输用户设备B的数据。
可见，在本方案中，网络设备先配置一个控制信息，这个控制信息被定义是用于确定授权资源用于传输复制数据的版本，然后网络设备发送这个控制信息；当用户设备接收到这个控制信息时，用户设备可根据这个控制信息明确网络设备期望该授权资源被用户设备用于服务哪个版本的数据。
