具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。

以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一信息和第二信息，只是为了区分不同的信息，而并不是表示这两种信息的内容、优先级、发送顺序或者重要程度等的不同。
为了便于理解本申请，首先对本申请涉及的概念进行解释。
设备到设备通信是基于设备到设备(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，车联网系统采用终端到终端直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。
在第三代合作伙伴计划(third generation partnership project，3GPP)中，定义了两种传输模式，包括模式一和模式二。在模式一中，终端的传输资源是是由基站分配的，终端根据基站分配的资源在侧行链路上进行数据传输。基站可以为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。在模式二中，车载终端在资源池中选取资源进行数据传输。
在3GPP中，D2D分成了不同的阶段进行研究。
一、ProSe(proximity based service)：在Rel-12/13中，设备到设备通信，是针对ProSe的场景进行了研究，主要针对公共安全类的业务。在ProSe中，通过配置资源池在时域上的位置，例如资源池在时域上非连续，达到UE在侧行链路上非连续发送/接收数据，从而达到省电的效果。
二、车联网(vehicle-to-everything，V2X)：在Rel-14/15中，车联网系统针对车车通信的场景进行了研究，其主要面向相对高速移动的车车、车人通信的业务。在V2X中，由于车载系统具有持续的供电，因此功率效率不是主要问题，而数据传输的时延是主要问题，因此在系统设计上要求终端设备进行连续的发送和接收。
三、可穿戴设备(FeD2D)：在Rel-14中，对于可穿戴设备通过手机接入网络的场景进行了研究，其主要面向是低移动速度以及低功率接入的场景。在FeD2D中，没有解决如何进行DRX配置的技术问题。
新空口(new radio，NR)V2X：NR V2X在长期演进(long term evolved，LTE)V2X的基础上，不局限于广播场景，进一步拓展到了单播和组播的场景，在这些场景下研究V2X的应用。类似于LTE V2X，NR V2X中也定义上述模式一和模式二两种资源分配方式。更进一步，用户可能处在一个混合的模式下，即既可以使用模式一进行资源的获取，又同时可以使用模式二进行资源的获取。该资源获取通过侧行链路授权的方式指示，即侧行链路授权指示相应的物理侧行链路控制信道(physical sidelink controlchannel，PSCCH)与物理侧行链路共享信道(physical sidelink shared channel，PSSCH)资源的时频位置。
不同于LTE V2X，除了无反馈的、UE自主发起的混合自动重传请求(hybrid automatic repeat request，HARQ)重传，NR V2X引入了基于反馈的HARQ重传，不限于单播通信，也包括组播通信。与LTE V2X相同，在NR V2X中，由于车载系统具有持续的供电，因此功率效率不是主要问题，而数据传输的时延是主要问题，因此在系统设计上要求终端设备进行连续的发送和接收。
在LTE系统或NR系统中，UE和基站之间的通信接口称为Uu口。在Uu接口上，为了降低UE一直监听物理下行控制信道(physical downlink control channel，PDCCH)所造成的功率消耗，UE会采用非连续接收(discontinous reception，DRX)机制。UE根据DRX配置不连续的监控PDCCH以达到省电的目的。网络通过配置一系列参数来控制UE的DRX行为。
在现有的Uu的DRX机制中，都是基于带有反馈的HARQ重传机制进行DRX的设计，因此DRX基于往返时延(round trip time，RTT)定时器(timer)(也即第一定时器)和re-transmission(retx)timer(第二定时器)实现，即在RTT timer运行期间，UE不需要进行下行监听，之后在retx timer运行期间进行下行监听。也就是说，当HARQ反馈激活时，接收端使用RTT timer和retx timer。当HARQ反馈去激活时，接收端只是用retx timer。
在侧行链路中，R16引入了HARQ反馈激活/去激活机制，即基于侧行链路控制信息(sidelinkcontrolinformation，SCI)中的指示，通知接收端是否进行反馈。在侧行链路系统中，发送端的资源授权可能来自于网络，HARQ反馈激活/去激活的决策由发送端决定，网络不知道，因此网络在给发送端提供资源时，由于不知道发送端是否会激活HARQ反馈，网络会在提供重传资源前，留出足够 的时间间隔，因此接收端可以采用DRX机制。另外，发送端的资源授权也可能来自于发送端在资源池选取的资源，由于HARQ反馈激活/去激活的决策由发送端决定，因此接收端也可以采用DRX机制。
