广播、组播是指一个发送设备发送的广播或组播数据，能够被一个或多个终端设备接收到。例如，预先定义业务数据在PC5接口上传输时所使用的目的层2标识(Destination Layer-2 ID)。当发送设备有该广播业务数据发送时，可以直接通过用户面协议栈进行发送，在媒体接入控制(media access control protocol，MAC)层和/或物理层(physical，PHY)层填充该广播业务对应的Destination Layer-2 ID。对该广播业务感兴趣的终端设备可以在PHY层监听是否有该广播业务对应的Destination Layer-2 ID的业务数据，并进行接收、解析，但本申请不限于此。
2、侧行链路中的单播通信方式
单播是终端设备一对一的通信方式，发送设备通过目的地址指示其发送的单播数据的接收设备，接收设备根据单播数据的目的地址确定该单播数据是否是发送给自己的单播数据，以及根据单播数据的源地址确定该单播数据是由哪个设备发送的。可选地，两个终端设备可以通过信令交互建立该两个设备之间的单播连接，单播连接建立完成后可以进行单播通信。
3、侧行链路传输模式1(mode1)
侧行链路mode1是指终端设备根据网络设备发送的侧行链路调度授权(sidelink grant)确定用于发送侧行链路数据的资源。该侧行链路调度授权用于授权该终端设备专用的发送 侧行链路数据的资源。例如，终端设备在发送侧行链路前，向网络设备上报缓存状态报告buffer status reports，BSR)以通知网络设备待发送的数据量，网络设备根据终端设备上报的数据量为其授权相应资源。
4、侧行链路传输模式2(mode2)
侧行链路mode2是指网络设备预先分配用于侧行链路的资源，多个终端设备可以该用于侧行链路的资源中竞争资源，在竞争到资源的情况下，终端设备可以在该竞争到的资源上发送侧行链路的数据。例如，终端设备根据测量该用于侧行链路的资源中的每个时频资源是否被占用、来选择未被占用的资源进行传输，但本申请不限于此。
下面结合附图详细说明本申请实施例提供的侧行链路的通信方法。
图2是本申请实施例提供的侧行链路的通信方法的一示意性流程图。
S210，第一终端设备确定一个或多个第一配置信息。
该一个或多个第一配置信息与一个或多个侧行链路相对应，每个该第一配置信息用于配置所对应的侧行链路的非连续接收(discontinuous reception，DRX)的相关参数。第一终端设备在一个或多个侧行链路进行DRX操作，并维护该一个或多个DRX的状态，该一个或多个DRX与该一个或多个侧行链路一一对应，一个侧行链路包括一个发送设备和一个接收设备。接收设备的标识和发送设备的标识可以来唯一标识一个侧行链路，也就是说，一个侧行链路可以通过接收设备的标识与发送设备的标识确定。

可选地，可以通过通信类型(例如，可以写作cast-type)来标识侧行连路的类型，通信类型可以包括广播、组播和单播。
例如，对于广播或组播，cast-type和发送设备的标识可以标识该发送设备与广播或组播的多个接收设备之间的侧行链路。或者，cast-type和接收设备的标识可以标识该接收设备与广播或组播的发送设备之间的一条侧行链路。或者，cast-type和发送设备的标识以及接收设备的标识可以标识该接收设备与发送设备之间的一条侧行链路。
该第一终端设备可以是该一个或多个DRX中一个DRX的发送设备，也可以是该一个或多个DRX中的一个DRX的接收设备。一个DRX的接收设备在DRX激活时间内接收该DRX对应的侧行链路的数据，该DRX的发送设备在该DRX的接收设备的DRX激活时间内向该DRX的接收设备发送数据。
因此，发送设备和接收设备均需要确定DRX的激活时间，以确保发送设备在接收设备的接收状态下发送数据。
一种实施方式中，一个DRX的接收设备向该一个DRX的发送设备发送消息A，该消息A包括该一个DRX的配置信息。
另一种实施方式中，一个DRX的发送设备向该一个DRX的接收设备发送消息B，该消息B包括该一个DRX的配置信息。
作为示例非限定，该消息A和/或该消息B可以是以下至少一种消息：
侧行链路无线资源控制(radio resource control，RRC)消息、***消息块(system  information block，SIB)、服务数据适配协议(service data adaptation protocol，SDAP)、分组数据汇聚层协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)、侧行链路控制信息(sidelink control information，SCI)或PC5信令(PC5-signalling，PC5-S)。
另一种实施方式中，第一终端设备接收网络设备发送的消息C，该消息C用于指示一个侧行链路的DRX的配置信息。也就是说，可以由网络设备为一个DRX的接收设备和/或发送设备配置该DRX的配置信息。该消息C可以是网络设备向第一终端设备发送的RRC消息或***消息。
另一种实施方式中，第一终端设备的***预配置信息中包括该一个或多个侧行链路的DRX的配置信息。
例如，每个终端设备***预配置一套用于侧行链路的DRX的配置信息，每个终端设备需要进行DRX操作的情况下，即根据***预配置的侧行链路的DRX配置信息维护DRX的状态，也就是说，该一个或多个DRX的配置信息相同，但本申请不限于此。
S220，第一终端设备根据每个该第一配置信息，维护每个该第一配置信息对应的非连续接收DRX的状态。
所述第一配置信息包括以下参数中的一种或多种：
该DRX的第一周期；
该DRX的第二周期，该第二周期小于该第一周期；
该DRX的起始时间偏移量；
第一计时器的参数，该第一计时器的参数用于指示每个DRX周期内DRX的激活时间；
第二计时器的参数，该第二计时器的参数用于指示接收设备在接收到调度一个HARQ进程的调度数据的侧行链路控制信息SCI后关闭接收该一个HARQ进程的传输的持续时长；
第三计时器的参数，该第三计时器的参数用于指示接收设备接收一个HARQ进程的调度重传数据的SCI的最大DRX激活时长；
第四计时器的参数，该第四计时器的参数用于指示接收设备接收到调度新传数据的SCI后保持DRX激活时间的时长；
第五计时器的参数，该第五计时器的参数的参数用于指示第二周期的DRX的持续时长。
第一终端设备可以根据每个DRX的周期和/或该起始时间偏移量确定该DRX的一个周期的起始时间，该时间偏移量可以包括起始偏移量和/或时隙偏移量。
在该一个或多个侧行链路中的一个侧行链路对应的DRX采用第一周期的情况下，该第一终端设备根据该侧行链路对应的DRX的该第一周期和/或该起始时间偏移量确定该DRX一个周期的起始时间，并启动或重启该侧行链路对应的DRX的第一计时器；该第一周期的DRX的每个周期的起始时间可以通过以下方式确定：
[(DFN×10)+subframe number]modulo(drx-LongCycle)＝drx-StartOffset
其中，DFN为起始时间所在的直接帧号(direct frame number，DFN)，subframe number为起始时间在该DFN中的所在的子帧的子帧号，drx-StartOffset为起始时间偏移量，drx-LongCycle为第一周期。
该起始时间为该subframe number开始的drx-SlotOffset，该drx-SlotOffset为时隙偏移量。第一终端设备在该该subframe number开始的drx-SlotOffset后启动或重启该第一计时器。
在该一个或多个侧行链路中的一个侧行链路对应的DRX采用第二周期的情况下，该第一终端设备根据该侧行链路对应的DRX的该第二周期和/或该起始时间偏移量，启动或重启该侧行链路对应的该第一计时器。在第一计时器运行期间，该DRX的接收设备处于DRX激活时间，能够接收该DRX对应的侧行链路的数据。该第一周期的DRX的每个周期的起始时间可以通过以下方式确定：
[(DFN×10)+subframe number]modulo(drx-ShortCycle)＝(drx-StartOffset)modulo(drx-ShortCycle)
其中，drx-ShortCycle为第一周期。
该起始时间为该subframe number开始的drx-SlotOffset。第一终端设备在该该subframe number开始的drx-SlotOffset后启动或重启该第一计时器。
例如图3所示，第一终端设备在侧行链路A与第二终端设备进行第一DRX操作，在侧行链路B与第三终端设备进行第二DRX操作，第一终端设备和第三终端设备根据该第一DRX的第一周期A和该第一DRX的起始时间偏移量A确定该第一DRX的起始时间，并启动该第一DRX的第一计时器A。第一终端设备为该第一DRX的发送设备，第一终端设备在第一计时器A运行期间可以向第二终端设备发送数据，也就是说，该第一终端设备可以在第一计时器A运行期间发送该第一DRX对应的该侧行链路A的数据。若第一终端设备没有待发送的侧行链路A的数据，第一终端设备在第一计时器A运行期间不向该第二终端设备发送数据。该第二终端设备在第一计时器A运行期间监测侧行链路A的数据。该第一计时器A运行期间属于该第一DRX的激活时间。
另外，若该第二DRX采用该第二DRX的第一周期，第一终端设备和第三终端设备在根据该第二DRX的第一周期B和该第二DRX的起始时间偏移量B确定该第二DRX的起始时间，并启动该第二DRX的第一计时器B，第一终端设备为该第二DRX的接收设备，在第一计时器B启动期间监测该第三设备发送的数据。该第一计时器B运行期间属于该第二DRX的激活时间
也就是说，第一终端设备根据一个或多个DRX中每个DRX所配置的第一周期和起始时间偏移量分别确定各个DRX的起始时间，并在各个DRX的起始时间启动或重启各个DRX对应的第一计时器。
一种实施方式中，终端设备在该一个或多个侧行链路中的一个侧行链路的DRX激活时间内发送或接收到第一SCI后，启动或重启第一HARQ进程对应的该第二计时器，和/或，停止该第一HARQ进程对应的该第三计时器，示例性的，该第一SCI用于调度该一个侧行链路中的新传数据或重传数据，该第一HARQ进程为该终端设备处理该新传数据或该重传数据的HARQ进程。
例如，若终端设备A在侧行链路B的第二DRX的激活时间内检测到第一SCI，终端设备A启动处理该新传数据或重传数据的HARQ进程的第二定时器。如果此时该HARQ进程的第三计时器正在运行，终端设备A停止该HARQ进程的第三计时器。
可选地，若该第一SCI调度的是新传数据，该侧行链路B的发送设备，即终端设备B，选择一个空的HARQ进程用于终端设备B处理该新传数据，例如，终端设备B正在通过 HARQ进程1处理与终端设备C的数据，HARQ进程0为空的HARQ进程，终端设备B可以选择HARQ进程0(即第一HARQ进程的一例)用于处理该新传数据。终端设备B将该HARQ进程0与终端设备A的标识相关联，或者说将该HARQ进程0与该侧行链路B相关联，该第一SCI中指示的HARQ进程的标识为HARQ进程0，例如图4所示。该终端设备A的标识可以是层1标识或层2标识，但本申请不限于此。可选地，该HARQ进程0可以与cast-type和终端设备A的标识相关联。
终端设备B向终端设备A发送该第一SCI后启动该HARQ进程0对应的第二计时器，并等待终端设备A的反馈，若终端设备A成功接收该新传数据，终端设备A释放该HARQ进程0，若未成功接收该新传数据，终端设备A继续使用该HARQ进程0进行数据重传。
若终端设备B还有更多数据要发送给终端设备A，终端设备B可以再选择一个空的HARQ进程(例如HARQ进程2)维护该数据并等待反馈；若终端设备B还有对其他终端设备发送的数据，终端设备B可以再选择一个空的HARQ进程。
终端设备A接收到该调度新传数据的第一SCI后，选择一个空的HARQ进程(例如，选择HARQ进程1，即第一HARQ进程的另一例)处理该新传数据，并且将该HARQ进程1与终端设备B的标识和该第一SCI指示的终端设备B的HARQ进程标识(即HARQ进程0)相关联，或者说将该侧行链路B与该HARQ进程0相关联。可选地，该HARQ进程1可以与cast-type和终端设备A的标识相关联，或该HARQ进程1可以与cast-type和终端设备A以及终端设备B的标识相关联。
终端设备A接收到该第一SCI后，启动该HARQ进程1对应的第二计时器，该第二计时器的时长可以通过第二DRX的配置信息确定。在该第二计时器运行期间，该终端设备A不接收该第二计时器对应的HARQ进程的数据。
若该第一SCI调度的是重传数据，终端设备A根据终端设备B的标识以及该第一SCI指示的终端设备B的HARQ进程标识为0，确定相关联的HARQ进程1，该HARQ进程1为终端设备A处理该重传数据的HARQ进程。接收到该第一SCI后，终端设备A启动该HARQ进程1对应的第二计时器，该第二计时器的时长通过第二DRX的配置信息确定。在该第二计时器运行期间，该终端设备A不接收该第二计时器对应的HARQ进程的数据。
可选地，若在终端设备A接收到该第一SCI前该HARQ进程1对应的第三计时器正在运行，终端设备A在接收到该第一SCI后停止该HARQ进程1对应的第三计时器、并启动该HARQ进程1对应的第二计时器。

可选地，在第三计时器超时后，启动或重启第二计时器或第三计时器。
例如，一个侧行链路的发送设备在配置授权(configured grant)的资源上发送的数据，并采用自动重传的方式时，发送设备可以利用周期性的CG资源进行传输。对于该侧行链路的接收设备来说，在无法准确获知发送设备自动重传的周期的情况下，在第三计时器超时后，可以周期性启动重传数据接收。如在第三计时器超时后，重启第二计时器或第三计 时器，直至达到或超过最大次数或最大时间。可选地，通过该侧行链路对应的第一配置信息可以包括最大次数或最大时间。或者，该最大次数或最大时间由发送设备在SCI中显式或隐式地配置。若发送设备不支持配置授权数据的自动重传，接收设备在第三计时器超时后，释放该HARQ进程1。
若该终端设备A反馈了ACK，或者说成功解码该第一SCI指示的新传数据或重传数据，在HARQ进程1的第二计时器超时后，该终端设备A不启动或不重启该HARQ进程1的第三计时器，并释放该HARQ进程1，同时停止该HARQ进程关联的第二计时器和/或第三计时器，使HARQ进程1变为空进程可以用于处理其他接收到的数据。
可选地，若该第一SCI调度的是新传数据，该终端设备A和终端设备B启动该第二DRX对应的第四计时器，在第四计时器运行期间该终端设备A处于第二DRX的激活时间，即该终端设备A在第四计时器运行期间监测该第二DRX对应的侧行链路B的数据，也就是说，监测该终端设备B发送的数据。
可选地，在第二DRX的第四计时器超时后，若该第二DRX被配置了的该第二周期，该终端设备A和终端设备B开始第二周期的该第二DRX，且启动或重启该第二DRX的第五计时器；若第二DRX没有被配置第二周期，该终端设备A和终端设备B开始第一周期的第二DRX操作。

可选地，在终端设备A启动了该第二DRX的第五计时器的情况下，若终端设备A在第五计时器运行期间未接收到该侧行链路B的数据，该终端设备A开始第一周期的第二DRX操作；若终端设备A在第五计时器运行期间接收到了该侧行链路B的数据，终端设备A重启该第五计时器。
示例性的，第一终端设备可以是上述示例中的终端设备A或终端设备B，即第一终端设备作为一个DRX的接收设备的情况下可以执行上述终端设备A的操作，第一终端设备作为一个DRX的发送设备的情况下可以执行上述终端设备B的操作。
一种实施方式中，该第一终端设备在该一个或多个侧行链路中的一个侧行链路中发送或接收到第一信息后，开始与该一个侧行链路对应的该第一周期的DRX操作，该第一信息用于指示该第一终端设备开始该第一周期的DRX操作。
例如，终端设备A在侧行链路A发送第一信息，通过该第一信息指示该侧行链路B的接收设备，即终端设备B，开始该侧行链路B对应的第一周期的该第一DRX。该第一终端设备在发送该第一信息后，开始第一DRX操作，也就是说根据第一DRX的第一周期确定该第一DRX的接收设备的DRX激活时间。终端设备B接收到该第一信息后，开始第一周期的该第一DRX，该第一周期是该第一DRX的配置信息确定的。
根据上述方案，第一终端设备根据侧行链路中该第一信息的接收设备和发送设备确定对应的第一DRX，并根据该第一DRX配置的第一周期，开始第一周期的DRX。能够实现第一终端设备针对侧行链路进行维护DRX维护。
可选地，如果该第一DRX的第五计时器正在运行，第一终端设备发送或接收到该第一信息后停止该第五计时器。
一种实施方式中，该第一终端设备在该一个或多个侧行链路中的一个侧行链路中发送或接收到第二信息后，开始与该一个侧行链路对应的该第二周期的DRX操作，该第二信息用于指示该第一终端设备开始该第二周期的DRX操作。
