  • Restriction 1 After removing some exceptions, the terminal device shall enable a certain retransmission resource selected to be indicated by the first-order SCI sent previously.
  • the above exceptions include: Situation 1: After the terminal device performs resource exclusion, it cannot select a resource that satisfies the time domain restriction from the resource set B.

  • Restriction 2 The terminal device should guarantee any two selected transmission resources. If the previous transmission resource requires HARQ feedback, the two resources are separated by at least a specified duration in the time domain. When the resource selection cannot satisfy the time domain restriction, depending on the implementation of the terminal device itself, the selection of some retransmission resources may be abandoned or the HARQ feedback may be deactivated for certain transmissions.

为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术方案进行说明。
●设备到设备(Device to Device，D2D)
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。
在3GPP中，D2D通信分成了以下不同的阶段进行研究：
近距离服务(Proximity based Service，ProSe)：设备到设备的通信是针对ProSe的场景进行了研究，其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，达到终端设备在侧行链路上非连续发送/接收的目的，从而达到省电的效果。
车辆到其他设备(Vehicle to Everything，V2X)：设备到设备的通信是针对车辆到其他设备的通信场景进行了研究，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。
进一步增强D2D(Further Enhancement Device to Device，FeD2D)：设备到设备的通信是针对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，在预研阶段3GPP结论为基站可以通过一个中继终端设备去配置远程终端设备的DRX参数。
●NR 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。
NR V2X在LTE V2X的基础上，不局限于广播场景，而是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。对于单播传输方式，其接收端只有一个终端设备。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。对于广播传输方式，其接收端是任意一个终端设备。
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(类似上述模式A)，模式2是终端设备选取传输资源(类似上述模式B)。更进一步，终端设备可能处在一个混合的模式下，具体地，既可以使用模式1进行资源的获取，又同时可以使用模式2进行资源的获取。
在NR V2X系统中，引入了侧行反馈机制，也即基于反馈的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)重传，侧行反馈机制不限于应用于单播场景，也可以应用于组播场景。
NR V2X中的模式2的资源选择方式：在NR V2X中，一些新的特征被引入，比如支持大量非周期业务、重传次数的增多以及更灵活的资源预留周期等。这些特征都对终端设备自主资源选择的模式(即模式2)有较大影响。因此，在上述模式B的基础上，重新设计适用于NR V2X的资源选择方案，称为模式2。
在模式2中，终端设备通过解码其他终端设备发送的行链路控制信息(Sidelink Control Information，SCI)和测量侧行链路接收功率，在资源池中选择未被其他终端设备预留或者被其他终端设备预留但接收功率较低的资源。模式2的资源选择算法分为两个主要步骤，即终端设备首先确定候选资源集合，再从候选资源集合中选择资源用于发送数据。以下对这两个步骤进行描述。
第一步：终端设备确定候选资源集合。具体地，
1)终端设备将资源选择窗内所有的可用资源作为资源集合A。
2)终端设备对资源集合A中的资源进行以下排除操作：
终端设备根据资源侦听窗内的侦听结果，判断资源是否被其他终端设备预留。终端设备根据未侦听时隙与侦听到的第一阶SCI进行资源排除，在完成资源排除后，如果资源集合A中的剩余资源数目小于一定比例，终端设备将提升参考信号接收功率(Reference Signal Received Power，RSRP)阈值，例如将RSRP阈值提升3dB，并重复执行前述的资源排除操作直到资源集合A中的剩余资源数目大于等于该比例。作为示例，该比例的取值范围为{20％，35％，50％}，具体比例的取值是以资源池为单位由网络配置或者预配置。最终，经过前述的资源排除操作后剩下资源集合B即为终端设备的候选资源集合。
第二步：终端设备在候选资源集合中选择传输资源。具体地，
终端设备在资源集合B中等概率随机选择一个或多个传输资源。需要指出的是，在选择多个传输资源时要满足如下时域上的限制：
限制一：在除去一些例外情况后，终端设备应使选择的某个重传资源能够被之前发送的第一阶SCI指示。上述例外情况包括：情况一：终端设备在进行资源排除后，无法从资源集合B中选择出满足该时域限制的资源。情况二：由于资源抢占、拥塞控制以及与上行业务冲突等因素，终端设备放弃传输从而导致某次重传的传输资源没有被之前发送的第一阶SCI指示。
限制二：终端设备应保证任意两个选择的传输资源，如果其中前一个传输资源需要HARQ反馈，则这两个资源在时域上至少间隔指定时长。当资源选择无法满足该时域限制时，取决于终端设备自身的实现，可以放弃选择某些重传资源或者针对某几次传输去激活HARQ反馈。
●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)，这样导致终端设备的功耗比较大。因此引入DRX机制，终端设备根据DRX配置不连续的监听PDCCH，以达到省电的目的。
DRX机制可以应用于处于空闲态的终端设备，也可以应用于处于连接态的终端设备。以下主要针对处于连接态的终端设备的DRX机制进行说明。
DRX的基本机制是为终端设备配置一个DRX周期(DRX cycle)。如图3所示，DRX周期由“On Duration”时间和“Opportunity for DRX”时间组成，其中，在“On Duration”时间(又称为激活时间)内，终端设备监听并接收PDCCH(即终端设备处于激活状态)；如果终端设备在“On Duration”时间内没有接收到PDCCH，就会停止连续监听，并在“Opportunity for DRX”时间(又称为睡眠时间)内转为睡眠状态，终端设备不接收PDCCH以减少功耗。除此以外，DRX机制还具有其他一系列的更为复杂的机制。
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。在DRX机制中，终端设备根据网络配置的DRX配置来控制终端设备的DRX行为，作为示例，DRX配置包括如下至少一种参数：drx-onDurationTimer、drx-SlotOffset、drx-StartOffset、drx-InactivityTimer、drx-RetransmissionTimerDL、drx-RetransmissionTimerUL、drx-LongCycle、drx-ShortCycle、drx-ShortCycleTimer、drx-HARQ-RTT-TimerDL、drx-HARQ-RTT-TimerUL。
在NR中，如果终端设备被配置了DRX配置，则终端设备需要在DRX激活时间(DRX Active Time)检测PDCCH，或者说，终端设备在DRX激活时间处于DRX激活状态。DRX激活时间有如下几个因素决定：
1)以下任意一个定时器运行期间属于DRX激活时间：·
DRX持续定时器(drx-onDurationTimer)；
DRX非激活定时器(drx-InactivityTimer)；
DRX下行重传定时器(drx-RetransmissionTimerDL)；
DRX上行重传定时器(drx-RetransmissionTimerUL)；
随机接入竞争解决定时器(ra-ContentionResolutionTimer)；
消息B响应窗口定时器(msgB-ResponseWindow)。
2)调度请求(Scheduling Request，SR)传输之后在悬挂(pending)的状态属于DRX激活时间。
3)在成功接收到随机接入前导码(Random Access Preamble)对应的随机接入响应(Random Access Response，RAR)后，在没有接收到指示新传数据的PDCCH的期间属于DRX激活时间。
对于drx-onDurationTimer，其开启或重启的时间点是基于配置的DRX周期在固定的时间点来确定的，如图3所示。drx-onDurationTimer运行期间，对应“On Duration”时间。
对于drx-InactivityTimer，其开启或重启的条件为：如果终端设备接收到一个指示下行或者上行初始传输(也即新传)的PDCCH，则终端设备开启或者重启drx-InactivityTimer，如图4所示。
目前，侧行链路传输中的DRX机制是按照方向定义的，不同方向的DRX机制是独立运行的。例如第一终端设备与第二终端设备之间在进行交互的过程中，第一终端设备和第二终端设备侧各自有独立的DRX机制。若第一终端设备向第二终端设备发送的传输1，则第二终端设备开启DRX非激活定时器，等待第一终端设备的后续传输；若第二终端设备需要针对传输1向第一终端设备进行响应，例如第二终端设备向第一终端设备发送传输2，则由于DRX机制是按照方向定义的，因此传输2需要等待第一终端设备进入DRX激活状态(即第一终端设备处于DRX激活时间)才能进行传输，这将会导致传输1和传输2中间的时延较长。可见，目前的DRX机制会导致第一终端设备和第二终端设备之间的交互会出现时延较大的问题。为此，提出了本申请实施例的以下技术方案。
需要说明的是，本申请实施例的技术方案可以应用于侧行链路通信，进一步，可以应用于侧行链路通信中的单播场景、组播场景、广播场景等。
