D2D通信基于侧行链路(Sidelink，SL)传输技术，与传统的蜂窝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D2D通信的方式(即设备到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D2D通信，第三代合作伙伴计划(Third Generation Partnership Project，3GPP)定义了两种传输模式：模式A和模式B。以下对模式A和模式B进行描述。
模式A：如图2-1所示，终端设备的传输资源是由基站分配的，终端设备根据基站分配的资源在侧行链路上进行数据的发送；基站可以为终端设备分配单次传输的资源，也可以为终端设备分配半静态传输的资源。
模式B：如图2-2所示，终端设备在资源池中选取一个资源进行数据的发送。具体地，终端设备可以通过侦听的方式在资源池中选取传输资源，或者通过随机选取的方式在资源池中选取传输资源。

新无线(New Radio，NR)-车辆到其他设备(Vehicle to Everything，V2X)
在NR-V2X中，需要支持自动驾驶，因此对车辆之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在NR-V2X系统中，引入了多种传输模式，包括模式1和模式2，其中，模式1是网络设备为终端设备分配传输资源(对应上述模式A)，模式2是终端设备选取传输资源(对应上述模式B)。
LTE-V2X支持广播传输方式，此外，在NR-V2X中引入了单播和组播的传输方式。对于单播传输方式，其接收端只有一个终端设备，如图3-1所示，UE1和UE2之间进行单播传输。对于组播传输方式，其接收端是一个通信组内的所有终端设备，或者是在一定传输距离内的所有终端设备，如图3-2所示，UE1、UE2、UE3和UE4构成一个通信组，其中UE1发送数据，该通信组内的其他终端设备都是接收端。对于广播传输方式，其接收端是任意一个终端设备，如图3-3所示，其中UE1是发送端，其周围的其他终端设备都是接收端。

NR Uu口的DRX机制
在无线网络中，如果终端设备一直监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)，根据网络侧发送的指示消息对数据进行收发，这样导致终端设备的功耗比较大。因此3GPP标准协议在LTE系统中引入DRX节能策略。
DRX的基本机制是为处于无线资源控制连接(RRC_CONNECTED)态的终端设备配置一个DRX周期(DRX cycle)。如图4所示，DRX cycle由“持续(On Duration)”和“DRX时机(Opportunity for DRX)”组成，其中，在“On Duration”时间内(又称为连续监听范围)，终端设备监听并接收PDCCH(即终端设备处于激活期)；如果终端在连续监听范围内没有接收到PDCCH，就会停止连续监听，在“Opportunity for DRX” 时间内转为DRX状态，终端设备不接收PDCCH以减少功耗(即终端设备处于休眠期)。在DRX操作中，终端设备根据网络配置的一些定时器参数来控制终端设备的on duration和off duration。需要说明的是，终端设备在“Opportunity for DRX”时间内会转为DRX状态，也即停止连续监听状态(off duration)。
在基于侧行链路的传输中，没有引入DRX机制，考虑到车联网业务可能是广播的方式发送的，所有的终端设备在不发送数据的时候都是处于接收状态，但是这样会导致终端设备的功耗很大，尤其对于手持终端而言，如何降低功耗是需要解决的问题。
在侧行链路增强的课题中，讨论在侧行链路传输中引入DRX机制，此时终端设备不是一直处于接收的状态，而是根据DRX配置，在on duration时间内接收数据，如果终端设备没有接收到数据，会转为DRX(off duration)，从而达到省电的目的。但是，对于单播和组播通信而言，发送端发送的数据需要被接收端接收，因此，在引入DRX机制后，如何保证侧行传输的可靠性是需要解决的问题。为此，提出了本申请实施例的以下技术方案。
图5为本申请实施例提供的数据传输方法的流程示意图，如图5所示，所述数据传输方法包括以下步骤：
步骤501：第一终端设备获取第一DRX配置信息，所述第一DRX配置信息用于确定第二终端设备的连续侦听时间范围。
本申请实施例中，所述第一终端设备为侧行数据的发送端，所述第二终端设备为侧行数据的接收端。
本申请实施例中，所述第一DRX配置信息用于确定所述第二终端设备的连续侦听时间范围，这里，所述连续侦听时间范围是根据所述第一DRX配置信息中的第一DRX参数确定的时间范围，该第一DRX参数用于确定所述第二终端设备的连续监听范围，即该第一时间范围是所述第二终端设备的连续侦听范围，例如该第一DRX参数是drx-onDurationTimer，drx-onDurationTimer运行期间对应的时间范围即为所述连续侦听时间范围。
本申请实施例中，对于单播通信或组播通信的场景，发送端需要获知接收端的DRX配置信息(即所述第一DRX配置信息)，从而保证发送端发送的数据能够被接收端接收。发送端(即所述第一终端设备)可以通过以下任意一种方式获取接收端(即所述第二终端设备)的DRX配置信息：
方式一：所述第一终端设备获取网络配置信息，所述网络配置信息包括所述第一DRX配置信息。

这里，所述第一DRX配置信息为所述第二终端设备的DRX配置信息。
这里，由组头终端设备为通信组内的各个终端设备配置DRX配置信息。组头终端设备可以为所述第一终端设备、或者所述第二终端设备、或者所述第三终端设备。其中，组头终端设备为所述第一终端设备的情况下，所述第一终端设备自然可以明确所述第一DRX配置信息。组头终端设备为所述第二终端设备的情况下，所述第一终端设备可以从所述第二终端设备获取所述第一DRX配置信息。组头终端设备为所述第三终端设备的情况下，所述第一终端设备可以从所述第三终端设备获取所述第一DRX配置信息，不局限于此，所述第一终端设备还可以从所述第二终端设备获取所述第一DRX配置信息。
在一可选方式中，所述第一DRX配置信息携带在侧行链路控制信息(Sidelink Control Information，SCI)中、或者PC5-RRC信令中、或者媒体接入控制控制单元(Media Access Control Control Element，MAC CE)中。
可选地，所述第一DRX配置信息携带在第二阶SCI中，即通过SCI格式0-2携带所述第一DRX配置信息。
例如：所述第二终端设备或第三终端设备向所述第一终端设备发送SCI，所述SCI携带所述第一DRX配置信息。具体地，所述第二终端设备或第三终端设备发送的SCI包括第一阶SCI(SCI格式0-1)和第二阶SCI(SCI格式0-2)，所述第一DRX配置信息携带在第二阶SCI中。其中，第一阶SCI用于指示该SCI调度的PSSCH的传输资源，第二阶SCI用于指示解调该SCI调度的PSSCH的参数。
例如：所述第二终端设备或第三终端设备向所述第一终端设备发送PC5-RRC信令，所述PC5-RRC信令携带所述第一DRX配置信息。具体地，所述第二终端设备或第三终端设备和所述第一终端设备建立连接时，通过PC5-RRC信令携带所述第一DRX配置信息。
例如：所述第二终端设备或第三终端设备向所述第一终端设备发送侧行数据，该侧行数据的MAC CE中携带所述第一DRX配置信息。具体地，述第二终端设备或第三终端设备发送的PSSCH中承载侧行数据，该侧行数据的MAC CE中包括所述第一DRX配置信息。
在一可选方式中，所述第一DRX配置信息包括但不限于以下至少一种DRX参数：

需要说明的是，按照以上方式可以实现所述第一终端设备获取所述第二终端设备的DRX配置信息(即所述第一DRX配置信息)，不局限于此，所述第二终端设备还可以按照以上方式获取所述第一终端设备的DRX配置信息(针对所述第一终端设备为侧行数据的接收端，所述第二终端设备为侧行数据的发送端的场景)。即所述第一终端设备和所述第二终端设备之间可以按照上述方式交互DRX配置信息。
在一可选方式中，不同的终端设备可能具有不同的DRX配置信息，如UE1和UE2在两个小区中，网络为UE1和UE2配置DRX配置信息，而两个小区的基站可 以配置不同的DRX参数，因此UE1和UE2可以具有不同的DRX配置信息。如图6所示，UE1和UE2要进行侧行数据传输，如果没有交互DRX配置信息，会导致一个终端设备发送侧行数据的时刻处于另一个终端设备的off duration期间，导致另一个终端设备不能正确接收该侧行数据。为此，需要两个终端设备之间交互DRX配置信息。
步骤502：所述第一终端设备在所述第二终端设备的连续侦听时间范围内向所述第二终端设备发送侧行数据。
本申请实施例中，所述第一终端设备和所述第二终端设备通过交互DRX配置信息，可以获知对方的DRX配置信息，因此，所述第一终端设备在发送侧行数据时，会在所述第二终端设备的连续侦听时间范围内(即on duration期间)发送侧行数据，从而保证所述第二终端设备可以正确接收该侧行数据。同理，所述第二终端设备在发送侧行数据时，会在所述第一终端设备的连续侦听时间范围内(即on duration期间)发送侧行数据，从而保证所述第一终端设备可以正确接收该侧行数据。
进一步，在一可选实施方式中，所述第一终端设备向所述第二终端设备发送第一指示信息，所述第一指示信息用于确定所述第一终端设备下一次传输侧行数据的时刻；其中，所述第一指示信息用于所述第二终端设备调整所述第二终端设备的连续侦听时间范围，所述第一终端设备下一次传输侧行数据的时刻位于所述连续侦听时间范围内。

这里，在所述第一定时器运行期间(或者说失效之前)，所述第二终端设备处于连续监听(即on duration)状态，所述第一定时器运行期间对应的时间即为所述第二终端设备的连续侦听时间范围。这里，所述第一定时器例如是第一DRX参数确定的定时器(例如drx-onDurationTimer)，或者是第二DRX参数确定的定时器(例如drx-InactivityTimer)，或者是其他的DRX参数确定的定时器。
图7为本申请实施例提供的参数调整方法的流程示意图，如图7所示，所述参数调整方法包括以下步骤：
步骤701：第二终端设备接收第一终端设备发送的第一指示信息，所述第一指示信息用于确定所述第一终端设备下一次传输侧行数据的时刻。
本申请实施例中，所述第一终端设备为侧行数据的发送端，所述第二终端设备为侧行数据的接收端。
在一可选方式中，第二终端设备接收所述第一终端设备在第一时刻发送的SCI，所述SCI携带第一指示信息，所述第一指示信息用于指示第一时间间隔；其中，所述第一终端设备下一次传输侧行数据的时刻为所述第一时刻加上所述第一时间间隔。
本申请实施例的技术方案可以但不局限于应用于NR-V2X场景，在NR-V2X中，支持周期性业务和非周期业务。对于周期性业务，当终端设备选取传输资源时，可以预留资源用于传输下一个侧行数据，是否支持终端设备为下一个侧行数据预留传输资源通常是可配置的，通过参数“reserveResourceDifferentTB”来表示，当该参数取值 为第一值(例如是“enable“)时，表示终端设备可以为下一个侧行数据预留传输资源，当该参数取值为第二值(例如是“disable”)，表示终端设备不能为侧行数据预留传输资源。进一步，可以通过参数“reservationPeriodAllowed”配置终端设备可以预留的资源的周期，该参数取值例如是{0,20,50，100,200,300,400,500,600,700,800,900,1000}ms等。如图8所示，终端设备在时刻n选取两个资源，分别位于n+t1、n+t2，该两个资源是用于传输第一侧行数据的(包括首次传输和重传)，资源池允许该终端设备为下一个侧行数据预留传输资源，即参数reserveResourceDifferentTB取值为enable，并且终端的业务周期是100ms，因此终端设备会在SCI中携带第一指示信息，例如该第一指示信息是resource reservation period，并且该第一指示信息指示100ms，即表示终端设备会预留100ms后的两个资源，即n+100+t1、n+100+t2对应的两个资源，这两个资源是用于传输第二侧行数据的(包括首次传输和重传)。当终端设备有新的侧行数据到达时，可以使用n+100+t1、n+100+t2对应的两个资源进行传输。以上是以两个资源为例，若终端设备选取了N个资源，通过SCI中的第一信息域指示该N个传输资源的时频信息，并且通过SCI中的第二信息域(如resource reservation period)指示预留下一个周期的N个资源，并且该下一个周期中的N个资源用于传输不同的侧行数据。
步骤702：所述第二终端设备根据所述第一指示信息，调整所述第二终端设备的连续侦听时间范围，所述第一终端设备下一次传输侧行数据的时刻位于所述连续侦听时间范围内。
进一步，所述第二终端设备可以采用以下任意一种方式调整所述第二终端设备的连续侦听时间范围：
A)所述第二终端设备调整第一DRX配置信息中的一个或多个DRX参数，所述一个或多个DRX参数用于确定所述第二终端设备的连续侦听时间范围，所述第一终端设备下一次传输侧行数据的时刻位于所述连续侦听时间范围内。
B)所述第二终端设备在所述下一次传输侧行数据的时刻之前启动第一定时器，所述第一定时器用于确定所述第二终端设备的连续侦听时间范围，所述第一终端设备下一次传输侧行数据的时刻位于所述连续侦听时间范围内。
这里，在所述第一定时器运行期间(或者说失效之前)，所述第二终端设备处于连续监听(即on duration)状态，所述第一定时器运行期间对应的时间即为所述第二终端设备的连续侦听时间范围。这里，所述第一定时器例如是第一DRX参数确定的定时器(例如drx-onDurationTimer)，或者是第二DRX参数确定的定时器(例如drx-InactivityTimer)，或者是其他的DRX参数确定的定时器。
本申请实施例中，当所述第一终端设备通过SCI指示当前PSSCH的传输资源时，可以同时指示为下一个侧行数据传输预留资源(即通过所述SCI携带的第一指示信息指示为下一个侧行数据传输预留资源)，所述第二终端设备接收该SCI，获取其携带的第一指示信息，通过所述第一指示信息可以获知所述第一终端设备下一个侧行数据传输的时刻，因此，所述第二终端设备可以通过调整DRX参数以使得当所述第一终端设备发送下一个侧行数据时，所述第二终端设备处于on duration时期，从而可以正确接收该侧行数据。
如图9-1所示，(a)是UE1(发送端)预留资源的示意图，(b)是UE2(接收端)的DRX图样，当UE2在n+t1接收到UE1的SCI，并且获知UE1预留了n+100+t1时刻的传输资源，因此UE2会调整DRX参数，即从(b)所示的DRX图样调整为(c)所示的DRX图样，从而使得UE1在n+100+t1时发送的侧行数据处于UE2的on duration内，因此UE2可以接收UE1发送的该侧行数据。
如图9-2所示，(a)是UE1(发送端)预留资源的示意图，(b)是UE2(接收端)的DRX图样，当UE2在n+t1接收到UE1的SCI，并且获知UE1预留了n+100+t1时刻的传输资源，因此UE2会在n+100+t1时刻之前启动第一定时器(例如drx-onDurationTimer或者drx-InactivityTimer)，从而扩大所述第二终端设备的连续侦听时间范围，使得n+100+t1时刻位于所述第二终端设备的连续侦听时间范围内，因此UE2可以接收UE1发送的该侧行数据。
本申请实施例中，所述第二终端设备获知所述第一终端设备下一次传输侧行数据的时刻后，调整自身的一个或多个DRX参数或者在下一次接收侧行数据之前启动第一定时器，从而使得所述第一终端设备下一次传输侧行数据的时刻位于所述第二终端设备的连续侦听时间范围内，从而所述第二终端设备可以正确接收所述第一终端设备发送的侧行数据，进而保证了侧行传输的可靠性。
