目前的方案，在用户终端与基站通信时，仅针对用户终端配置省电机制。然而，在利用sidelink接口进行用户终端之间通信的情况下，通信的两端都具有省电需求。而目前的省电机制，是针对用户终端与基站通信的用户设备(User Equipment，Uu)接口而设计的，无法应用于上述的sidelink接口。因而，在目前的用户终端之间通过边链路进行通信时，无法满足用户终端的省电需求。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开具体实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
本公开的技术方案，可以应用于各种通信系统，例如：全球移动通讯系统(Global System of Mobile communication，GSM)，码分多址(Code Division Multiple Access,CDMA)系统，宽带码分多址(Wideband Code Division Multiple Access,WCDMA)，通用分组无线业务(General Packet Radio Service,GPRS)，LTE/增强长期演进(Long Term Evolution Advanced,LTE-A)，NR(New Radio)等。
UE也可称之为终端设备(Mobile Terminal)、移动用户设备等，可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信，用户设备可以是终端设备，如移动电话(或称为“蜂窝”电话)和具有终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。
基站，可以是GSM或CDMA中的基站(Base Transceiver Station,BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(evolutional Node B,eNB或e-NodeB)及5G基站(gNB)，本公开并不限定，但为描述方便，下述实施例以gNB为例进行说明。
长期演进(Long Term Evolution，LTE)系统，支持边链路sidelink通信，用于UE之间，可以直接进行数据传输而不用通过基站。目前的边链路sidelink通信，主要包括广播(broadcast)、组播(groupcast)、单播(unicast)的传输形式。
非连续接收DRX：被配置于用户终端的目的是节电。处于DRX状态的用户终端，不需要连接监听控制信道，从而可以省电。但是，如果用户终端长时间不监听控制信道，一旦有数据达到，将会增加数据传输的时延。为了兼顾省电和传输时延，根据用户终端监听信道的时间长短，可以将用户终端监听信道的时间分为DRX长周期和DRX短周期。如果用户终端数据量到达比较频繁或者业务对时延比较敏感，则可以配置DRX短周期；如果用户终端的数据量比较稀疏且对时延不敏感，则可以配置DRX长周期。
DRX持续监听定时器(OnDuration timer)：在DRX持续监听定时器运行期间，用户终端需要持续监听网络的物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)。
DRX持续允许发送定时器(OnDuration timer)：在DRX持续允许发送定时器运行期间，允许发送数据调度或传输。
DRX非激活定时器(Inactivity timer)：DRX非激活定时器在用户终端收到数据调度PDCCH信令后的第一个符号启动，在DRX非激活定时器运行期间，用户终端需要持续监听控制信道或允许发送数据调度或传输。
混合自动重复请求(Hybrid Automatic Repeat Request，HARQ)RTT定时器(Round-Trip Time timer)：HARQ RTT定时器长度为从HARQ反馈时刻，到收到针对该进程的HARQ重传之间的最小时间间隔。只有当前进程对应的数据未成功解码，用户终端才会在该进程的HARQ NACK反馈之后的第一个符号启动该定时器。如果当前终端只有HARQ RTT定时器运行，则用户终端无需监听PDCCH或允许发送数据调度或传输。
重传定时器：HARQ RTT定时器超时后的下一个符号启动重传定时器。该重传定时器在运行期间，用户终端监听网络的控制信道或允许发送数据调度或传输，如果接收到针对该进程的调度/数据，则启动重传定时 器。
以下结合附图，详细说明本公开提供的技术方案。
本公开提供了一种边链路非连续接收方法，应用于第一用户终端101，换言之，所述方法可以由安装在终端设备的软件或硬件来执行。如图1所示，第一用户终端101与第二用户终端102之间通过边链路通信(即，第一用户终端101与第二用户终端102之间利用sidelink接口进行通信)；第二用户终端102与基站103之间通过3G/4G/5G网络进行通信。如图2所示，所述方法包括：
S21：在基于DRX机制的定时器控制下，在定时器中的目标接收定时器的运行期间，进行数据调度或传输的监听，或数据调度或传输的接收。
明显地，上述的进行数据调度或传输的监听，或数据调度或传输的接收基于边链路进行。其中，基于DRX机制的控制，定时器中的目标接收定时器可以多个同时运行，也可以单独的一个运行。可以理解地，在定时器中的目标接收定时器关闭后，停止进行数据调度或传输的监听，或数据调度或传输的接收。
另外，对于DRX机制的配置方式，可以是第二用户终端102将业务参数、省电需求上报到基站103，基站103根据业务参数、省电需求生成DRX机制数据，然后第二用户终端102接收基站103下发的DRX机制数据并配置，第一用户终端101再通过边链路接收第二用户终端102发送的DRX机制数据并配置。另外，对DRX机制的配置方式，还可以是第二用户终端102根据业务参数、省电需求直接生成DRX机制数据并配置，然后将DRX机制数据发送至第一用户终端101。当然地，对于DRX机制的配置方式不仅仅限于上述的两种，在此仅仅是举例说明。
本公开实施例提供的边链路非连续接收方法，在用户终端之间通过边链路进行通信时，通过在基于DRX机制的定时器控制下，仅在定时器中的目标接收定时器的运行期间，进行数据调度或传输的监听，或数据调度或传输的接收，可以满足通信的两端的省电需求。
可选地，作为其中一种实施方式，目标接收定时器包括持续监听接收定时器与非激活接收定时器，如图3所示，S21包括：
S31：在持续监听接收定时器运行期间内，监听第二用户终端102的数据调度或传输；
S32：如果接收到第二用户终端102的数据调度或传输，则开启非激活接收定时器，以持续监听第二用户终端102的数据调度或传输；
S33：在非激活接收定时器运行期间，如果再次接收到第二用户终端102传输的数据调度或传输，则重启非激活接收定时器。
可以理解地，当持续监听接收定时器、非激活接收定时器均超时后，停止监听第二用户终端102的数据调度或传输，从而满足第一用户终端的省电需求。
例如，如图4所示，图4中Y(垂直)方向的突出部分表示正在监听第二用户终端102的数据调度或传输，Y方向低平部分代表休眠状态(即停止监听第二用户终端102的数据调度或传输)，X(水平)方向为时间轴。例如，DRX周期设置为40ms，持续监听接收定时器的运行时长设置为5ms，非激活接收定时器的运行时长设置为8ms。根据配置好的DRX机制中的目标接收定时器和持续监听接收定时器的起始时刻，持续监听接收定时器开始运行，此时第一用户终端101进行数据调度或传输的监听与接收。例如，假设持续监听接收定时器起始位置为0，则接收第一用户终端101在0-5ms监听第二用户终端102的数据调度或传输，如果没有接收到数据调度或传输，则在5-40ms进入休眠状态，40ms-80ms是第二个DRX周期，在40ms-45ms持续监听接收定时器监听数据调度或传输，如果在44ms时接收到数据调度或者传输，则在44ms时启动非激活接收定时器，该非激活接收定时器在44-52ms有效。第一用户终端101在此期间持续监听，如果接收到数据调度或传输，则重启非激活接收定时器，直至非激活接收定时器超时，第一用户终端101进入休眠期，直到下一个DRX周期中，持续监听接收定时器再次醒来。上述的本质为在接收到数据传输/调度时，启动/重启的持续监听接收定时器，延长了对数据调度或传输进行监听的时间。
需要说明的是，上述的数据调度或传输引起的非激活接收定时器的启动/重启，可以仅仅是指新传输的数据，也可以既包括新传输的数据也包括 重传的数据，二者是可配置/选择的。
作为另一种实施方式，第一用户终端101还配置有HARQ反馈机制，定时器还包括HARQ往返时延接收定时器，目标接收定时器还包括重传接收定时器，如图5所示，所述方法还包括S51和S52。
在S51，在接收到数据后，如果向第二用户终端102反馈HARQ否定确认，则启动HARQ往返时延接收定时器。
当接收到数据时，如果发现数据丢包，则向第二用户终端102反馈HARQ否定确认，以告知第二用户终端102需要重新进行数据调度或数据传输，以保证数据传输的可靠性。
在S52，待HARQ往返时延接收定时器超时后，启动重传接收定时器，以监听第二用户终端102的重传数据调度或数据传输。
在HARQ往返时延接收定时器运行时，若有目标接收定时器同时运行，则监听数据调度或传输，若没有目标接收定时器同时运行，则停止监听数据调度或传输，从而满足第一用户终端101的省电需求。
例如，如图6所示，图6中，Y(垂直)方向突出部分表征处于监听数据调度或传输状态，X(水平)方向低平部分表征休眠状态，X(水平)方向为时间轴。在t1时刻，接收到数据传输/调度，启动非激活接收定时器，在t2时刻第二用户终端102反馈了HARQ否定确认，则启动HARQ往返时延接收定时器，非激活接收定时器在t3时刻超时。可以看出，在t3-t4时刻之间，由于没有任何目标接收定时器有效，第一用户终端101可以停止监听数据传输/调度，t4时刻HARQ往返时延接收定时器超时，则启动重传接收定时器，开始监听数据重传/调度，在t5时刻接收到第一次重传/调度，关闭重传接收定时器。在t6时刻针对第一次重传仍旧反馈HARQ否定确认，则重新启动HARQ往返时延接收定时器，第一用户终端101可以停止监听数据传输/调度，t7时刻HARQ往返时延接收定时器超时，则重新启动重传接收定时器，开始监听数据重传/调度，在t8时刻接收到第二次重传/调度，关闭重传接收定时器，第二用户终端102停止监听数据传输/调度，之后针对第二次重传反馈接收成功确认，则该HARQ进程结束。等待下个DRX周期的持续监听接收定时器运行时，再进行数据传输/调度的监听。
可以理解地，在本公开实施例，上述的第一用户终端101被作为接收端用户设备使用。事实上，对于任何一个用户终端而言，在不同的阶段，是可以既被作为接收端用户设备使用，也可以作为发送端用户设备使用。因此，在两个用户终端进行交互时，需要先确定接收端用户设备、发送端用户设备。可选地，定时器还包括目标发送定时器，在S21之前，如图7所示，所述方法还包括S20。
在S20，如果检测到定时器中的目标发送定时器、目标接收定时器均处于运行期间，则根据DRX机制，将目标发送定时器关闭。其中，DRX机制约定：第二用户终端102的发送优先级高于第一用户终端101的发送优先级。
可以理解地，当第一用户终端101的目标接收定时器处于运行期间的情况下，由于第一用户终端101、第二用户终端102具备相同的DRX机制，对应地，第二用户终端102的目标发送定时器也处于运行期间。可见，在目标发送定时器、目标接收定时器均处于运行期间的情况下，第一用户终端101、第二用户终端102均具有数据发送的需求，由于用户终端受收发硬件和干扰等因素的限制，很难做到同时进行接收和发送，此时，需要对第一用户终端101、第二用户终端102的数据调度或传输进行协调，以保证数据接收效果、省电特性。因此，需要通过发送优先级决定哪个用户终端先进行数据发送。
在DRX机制中，作为其中一种实施方式，约定发送优先级方式为：根据预配置的第一用户终端101的待处理的至少一个业务参数的最高优先级别、第二用户终端102的待处理的至少一个业务参数的最高优先级别，确定第一用户终端101相对于第二用户终端102的发送优先级。
如，第一用户终端101包括A、B、C，3个业务参数，发送优先级分别为2、2、3，第二用户终端102包括D、E、F，3个业务参数，发送优先级分别为1、2、3。可以看出，第一用户终端101的待处理的业务参数的最高优先级别为2、第二用户终端102的待处理的业务参数的最高优先级别为1，可见第二用户终端102的最高优先级别高于第一用户终端101的最高优先级别，因此，确定第二用户终端102优先进行数据发送。
在DRX机制中，作为另一种实施方式，约定发送优先级方式还可以为：根据第一用户终端101运行的目标发送定时器的类型、目标接收定时器的类型，确定第一用户终端101相对于第二用户终端102的发送优先级。
例如，DRX机制约定：重传发送定时器的优先级高于持续监听接收定时器的优先级。在第一用户终端101的持续运行发送定时器、与重传接收定时器同时运行的情况下，第二用户终端102的持续监听接收定时器与重传发送定时器也同时运行，此时，关闭第一用户终端101的持续运行发送定时器与第二用户终端102的持续监听接收定时器；此时仅存在第二用户终端102的重传发送定时器与第一用户终端101重传接收定时器运行，即重传数据优先发送。
在DRX机制中，作为另一种实施方式，约定发送优先级方式还可以为：根据第一用户终端101运行的目标发送定时器、目标接收定时器运行时所处的时刻，确定第一用户终端101相对于第二用户终端102的发送优先级。
例如，如果配置的DRX周期为640ms，DRX机制约定：在DRX周期的0-320ms，第一用户终端101的发送优先级高于第二用户终端的发送优先级；320-640ms，第二用户终端102的发送优先级高于第一用户终端101的发送优先级。因此，在DRX周期的0-320ms期间，第一用户终端101可以根据DRX机制开启目标发送定时器，第二用户终端102可以根据DRX机制开启目标接收定时器，以确定第一用户终端101优先发送数据。在DRX周期的320-640ms期间，第二用户终端102可以根据DRX机制开启目标发送定时器，第一用户终端101可以根据DRX机制开启目标接收定时器，以确定第二用户终端101优先发送数据。
再例如，如果配置的DRX周期为640ms，DRX机制约定：第一用户终端101持续允许发送定时器起始点为0ms，第二用户终端102的持续允许发送定时器起始点为160ms，则第一用户终端101在0-160ms的发送优先级高于第二用户终端102的发送优先级，第二用户终端102在160-640ms的发送优先级高于第一用户终端101的发送优先级。可以理解地，在DRX 周期的0-160ms期间，第一用户终端101可以根据DRX机制在0-160ms期间从0ms开始的配置时间段(如0-20ms或0-40ms等)开启持续允许发送定时器，第二用户终端102可以根据DRX机制在0-160ms期间从0ms开始的配置时间段(如0ms-20ms或0-40ms等)开启持续监听定时器，以确定第一用户终端101优先发送数据。在DRX周期的160-640ms期间，第二用户终端102可以根据DRX机制在160-640ms期间从160ms开始的配置时间段(如160ms-180ms或160-200ms)开启持续允许发送定时器，第一用户终端101可以根据DRX机制在160-640ms期间从160ms开始的配置时间段(如160ms-180ms或160-200ms)开启持续监听定时器，以确定第二用户终端102优先发送数据。
可以理解地，上述的第一用户终端101相对于第二用户终端102的发送优先级确定方式仅仅是举例说明，在具体应用中，可以根据实际需求而确定。
请参阅图8，本公开还提供了一种边链路非连续接收装置800，应用于第一用户终端101。需要说明的是，本公开所提供的边链路非连续接收装置800，其基本原理及产生的技术效果和上述实施例相同，为简要描述，本实施例部分未提及之处，可参考上述提供的边链路非连续接收方法的实施例中相应内容。如图1所示，第一用户终端101与第二用户终端102之间通过边链路通信(即第一用户终端101与第二用户终端102之间利用sidelink接口进行通信)；第一用户终端101与基站103之间通过3G/4G/5G网络进行通信。如图8所示，边链路非连续接收装置800包括：
信息接收单元801，被配置成在基于DRX机制的定时器控制下，在定时器中的目标接收定时器的运行期间，进行数据调度或传输的监听，或数据调度或传输的接收。
明显地，上述的进行数据调度或传输的监听，或数据调度或传输的接收基于边链路进行。其中，基于DRX机制的控制，定时器的中的目标接收定时器可以多个同时运行，也可以单独的一个运行。可以理解地，在定时器中的目标接收定时器关闭后，停止进行数据调度或传输的监听，或数据调度或传输的接收。
另外，对于DRX机制的配置方式，可以是第二用户终端102将业务参数、省电需求上报到基站103，基站103根据业务参数、省电需求生成DRX机制数据，然后第二用户终端102接收基站103下发的DRX机制数据并配置，第一用户终端101再通过边链路接收第二用户终端102发送的机制数据并配置；另外，对DRX机制的配置方式，还可以是第二用户终端102根据业务参数、省电需求直接生成DRX机制数据并配置，然后将DRX机制数据发送至第一用户终端101。当然地，对于DRX机制的配置方式不仅仅限于上述的两种，在此仅仅是举例说明。
本公开实施例提供的边链路非连续接收装置800，在用户终端之间通过边链路进行通信时，通过在基于DRX机制的定时器控制下，仅在定时器中的目标接收定时器的运行期间，进行数据调度或传输的监听，或数据调度或传输的接收，可以满足通信的两端的省电需求。
可选地，目标接收定时器包括持续监听接收定时器、非激活接收定时器，具体地，信息接收单元801被配置成在持续监听接收定时器运行期间内，监听第二用户终端102的数据调度或传输。
如图9所示，所述装置800还包括：定时器开启单元901，被配置成如果接收到第二用户终端102的数据调度或传输，则开启非激活接收定时器，以持续监听第二用户终端102的数据调度或传输。
定时器开启单元901还可以被配置成在非激活接收定时器运行期间，如果再次接收到第二用户终端102传输的数据调度或传输，则重启非激活接收定时器。
可选地，第一用户终端101还配置有HARQ反馈机制，定时器还包括HARQ往返时延接收定时器，目标接收定时器还包括重传接收定时器，如图10所示，所述装置800还包括：
信息发送单元1001，被配置成在接收到数据后，如果向第二用户终端102反馈HARQ否定确认，则启动HARQ往返时延接收定时器。
定时器开启单元901还可以被配置成待HARQ往返时延接收定时器超时后，启动重传接收定时器，以监听第二用户终端102的重传数据调度或数据传输。
定时器还包括目标发送定时器，如图11所示，所述装置800还包括：
定时器关闭单元1101，被配置成如果检测到定时器中的目标发送定时器、目标接收定时器均处于运行期间，则根据DRX机制，将目标发送定时器关闭，其中，DRX机制约定：第二用户终端102的发送优先级高于第一用户终端101的发送优先级。
具体地，在DRX机制中，约定发送优先级方式可以为：根据预配置的第一用户终端101的待处理的至少一个业务参数的最高优先级别、第二用户终端102的待处理的至少一个业务参数的最高优先级别，确定第一用户终端101相对于第二用户终端102的发送优先级。
在DRX机制中，约定发送优先级方式还可以为：根据第一用户终端101运行的目标发送定时器的类型、目标接收定时器的类型，确定第一用户终端101相对于第二用户终端102的发送优先级。
在DRX机制中，约定发送优先级方式可以为：根据第一用户终端101运行的目标发送定时器、目标接收定时器运行时所处的时刻，确定第一用户终端101相对于第二用户终端102的发送优先级。
本公开还提供了一种边链路非连续发送方法，应用于第二用户终端102，如图1所示，第二用户终端102与第一用户终端101之间通过边链路通信(即用户终端之间利用sidelink接口进行通信)；第二用户终端102与基站103之间通过3G/4G/5G网络进行通信。如图12所示，边链路非连续发送方法包括：
S121：在基于DRX机制的定时器控制下，在定时器中的目标发送定时器的运行期间，允许向第一用户终端101进行数据调度或传输，或向第一用户终端101进行数据调度或传输。
明显地，上述的允许向第一用户终端101进行数据调度或传输，或向第一用户终端101进行数据调度或传输基于边链路进行。其中，基于DRX机制的控制，定时器的中的目标接收定时器可以多个同时运行，也可以单独的一个运行。可以理解地，在定时器中的目标发送定时器关闭后，停止允许向第一用户终端101进行数据调度或传输，或向第一用户终端101进行数据调度或传输。
另外，对于DRX机制的配置方式，可以是第二用户终端102将业务参数、省电需求上报到基站103，基站103根据业务参数、省电需求生成DRX机制数据，然后第二用户终端102接收基站103下发的DRX机制数据并配置，第一用户终端101再通过边链路接收第二用户终端102发送的机制数据并配置；另外，对DRX机制的配置方式，还可以是第二用户终端102根据业务参数、省电需求直接生成DRX机制数据并配置，然后将DRX机制数据发送至第一用户终端101。当然地，对于DRX机制的配置方式不仅仅限于上述的两种，在此仅仅是举例说明。
本公开实施例提供的边链路非连续发送方法，在用户终端之间通过边链路进行通信时，通过在基于DRX机制的定时器控制下，仅在定时器中的目标接收定时器的运行期间，允许向第一用户终端101进行数据调度或传输，或向第一用户终端101进行数据调度或传输，可以满足通信的两端的省电需求。
可选地，目标发送定时器包括持续允许发送定时器、非激活发送定时器，如图13所示，S121包括：
S131：在持续允许发送定时器运行期间内，允许向第一用户终端101进行数据调度或传输。
S132：如果向第一用户终端101进行数据调度或传输，则开启非激活发送定时器，以持续允许向第一用户终端101进行数据调度或传输。
S133：在非激活发送定时器运行期间，如果再次向第一用户终端101进行数据调度或传输，则重启非激活发送定时器。
当持续允许发送定时器、非激活发送定时器均超时后，停止允许第二用户终端102的数据调度或传输。
例如，如图14所示，图14中Y(垂直)方向的突出部分表示正在允许第二用户终端102的数据调度或传输，Y方向低平部分代表休眠状态(即停止允许第二用户终端102的数据调度或传输)，X(水平)方向为时间轴。例如，DRX周期设置为40ms，持续允许发送定时器的运行时长设置为5ms，非激活发送定时器的运行时长设置为8ms。根据配置好的DRX中的目标接收定时器和持续允许发送定时器的起始时刻，持续允许发 送定时器开始运行，此时第二用户终端102允许数据调度或传输。例如，假设持续允许发送定时器起始位置为0，则第二用户终端102在0-5ms允许数据调度或传输，如果没有发送数据调度或传输，则在5-40ms进入休眠状态。40ms-80ms是第二个DRX周期，在40ms-45ms持续允许发送定时器允许数据调度或传输，如果在44ms时发送数据调度或者传输，则在44ms时启动非激活发送定时器，该非激活发送定时器在44-52ms有效，第二用户终端102在此期间持续允许数据调度或传输，如果发出数据调度或传输，则会重启非激活发送定时器，直至非激活发送定时器超时，则第二用户终端102进入休眠期，直到下一个DRX周期中，持续允许发送定时器再次醒来。上述的本质为在发送出数据传输/调度时，启动/重启持续允许发送定时器，延长了对数据调度或传输进行允许的时间。
需要说明的是，上述的发出数据调度或传输引起的非激活发送定时器的启动/重启，可以仅仅是指新传输的数据，也可以既包括新传输的数据也包括重传的数据，二者是可配置/选择的。
可选地，第二用户终端102还配置有HARQ重传机制，定时器还包括HARQ往返时延发送定时器，目标发送定时器还包括重传发送定时器。如图15所示，所述方法还包括S152和S153。
在S152，如果接收到第一用户终端101反馈的HARQ否定确认，则启动HARQ往返时延发送定时器。
在S153，待HARQ往返时延发送定时器超时后，启动重传发送定时器，以允许向第一用户终端101进行重传数据调度或数据传输。
当接收到向第一用户终端101发出数据时，接收到第一用户终端101反馈HARQ否定确认，则说明数据发送失败，从而需要重新进行数据调度或数据传输。
例如，如图16所示，图16中，Y(垂直)方向突出部分表征处于监听数据调度或传输状态，X(水平)方向低平部分表征休眠状态，X(水平)方向为时间轴。在t1时刻，发出数据传输/调度，启动非激活发送定时器，在t2时刻接收到第一用户终端101反馈的HARQ否定确认，则启动HARQ往返时延发送定时器，非激活发送定时器在t3时刻超时。可以看 出，在t3-t4时刻之间，由于没有任何目标发送定时器有效，第二用户终端102可以停止允许数据传输/调度，t4时刻HARQ往返时延发送定时器超时，则启动重传发送定时器，开始允许数据重传/调度，在t5时刻进行第一次重传/调度，然后关闭重传发送定时器。在t6时刻接收第一用户终端101针对第一次重传反馈的HARQ否定确认，则重新启动HARQ往返时延发送定时器，第二用户终端102可以停止允许数据传输/调度，t7时刻HARQ往返时延发送定时器超时，则重新启动重传发送定时器，开始允许数据重传/调度，在t8时刻发送到第二次重传/调度，关闭重传发送定时器，第二用户终端102停止允许数据传输/调度，之后针对第二次重传反馈发送成功确认，则该HARQ进程结束。等待下个DRX周期的持续允许发送定时器运行时，再允许进行数据传输/调度。
可以理解地，在本公开实施例，上述的第二用户终端102被作为发送端用户设备使用。事实上，对于任何一个用户终端而言，在不同的阶段，是可以既被作为接收端用户设备使用，也可以作为发送端用户设备使用。因此，在两个用户终端进行交互时，需要先确定接收端用户设备、发送端用户设备。可选地，定时器还包括目标接收定时器，在S121之前，如图17所示，所述方法还包括：
S120：如果检测到定时器中的目标发送定时器、目标接收定时器均处于运行期间，则根据DRX机制，将目标接收定时器关闭。
其中，DRX机制约定：第二用户终端102的发送优先级高于第一用户终端101的发送优先级。可以理解地，当第二用户终端102的目标接收定时器处于运行期间的情况下，由于第一用户终端101、第二用户终端102具备相同的DRX机制，对应地，第一用户终端101的目标发送定时器也处于运行期间。可见，在目标发送定时器、目标接收定时器均处于运行期间的情况下，第一用户终端101、第二用户终端102均具有数据发送的需求，由于用户终端受收发硬件和干扰等因素的限制，很难做到同时进行接收和发送，此时，需要对第一用户终端101、第二用户终端102的数据调度或传输进行协调，以保证数据接收效果、省电特性。因此，需要通过发送优先级决定哪个用户终端先进行数据发送。
可选地，在DRX机制中，作为其中一种实施方式，约定发送优先级方式为：根据预配置的第一用户终端101的待处理的至少一个业务参数的最高优先级别、第二用户终端102的待处理的至少一个业务参数的最高优先级别，确定第一用户终端101相对于第二用户终端102的发送优先级。
如，第一用户终端101包括A、B、C，3个业务参数，发送优先级分别为2、2、3，第二用户终端102包括D、E、F，3个业务参数，发送优先级分别为1、2、3.可以看出，第一用户终端101的待处理的业务参数的最高优先级别为2、第二用户终端102的待处理的业务参数的最高优先级别为1，可见第二用户终端102的最高优先级别高于第一用户终端101的最高优先级别。
在DRX机制中，作为另一种实施方式，约定发送优先级方式为：根据运行的目标发送定时器的类型、目标接收定时器的类型，确定第一用户终端101相对于第二用户终端102的发送优先级。
例如，DRX机制约定：重传发送定时器的优先级高于持续监听接收定时器的优先级。在第一用户终端101的持续运行发送定时器、与重传接收定时器同时运行的情况下，第二用户终端102的持续监听接收定时器与重传发送定时器也同时运行，此时，关闭第一用户终端101的持续运行发送定时器与第二用户终端102的持续监听接收定时器；此时仅存在第二用户终端的重传发送定时器与第一用户终端重传接收定时器运行，即重传数据优先发送。
在DRX机制中，作为另一种实施方式，约定发送优先级方式为：根据运行的目标发送定时器、目标接收定时器运行时所处的时刻，确定第一用户终端101相对于第二用户终端102的发送优先级。
例如，如果配置的DRX周期为640ms，DRX机制约定：在DRX周期的0-320ms，第一用户终端101的发送优先级高于第二用户终端的发送优先级；320-640ms，第二用户终端102的发送优先级高于第一用户终端101的发送优先级。因此，在DRX周期的0-320ms期间，第一用户终端101可以根据DRX机制开启的目标发送定时器，第二用户终端102可以根据DRX机制开启目标接收定时器，以确定第一用户终端101优先发送数据。在 DRX周期的320-640ms期间，第二用户终端102可以根据DRX机制开启目标发送定时器，第一用户终端101可以根据DRX机制开启目标接收定时器，以确定第二用户终端101优先发送数据。
再例如，如果配置的DRX周期为640ms，DRX机制约定：第一用户终端101持续允许发送定时器起始点为0ms，第二用户终端102的持续允许发送定时器起始点为160ms，则第一用户终端101在0-160ms的发送优先级高于第二用户终端102的发送优先级，第二用户终端102在160-640ms的发送优先级高于第一用户终端101的发送优先级。可以理解地，在DRX周期的0-160ms期间，第一用户终端101可以根据DRX机制在0-160ms期间从0ms开始的配置时间段(如0-20ms或0-40ms等)开启持续允许发送定时器，第二用户终端102可以根据DRX机制在0-160ms期间从0ms开始的配置时间段(如0ms-20ms或0-40ms等)开启持续监听定时器，以确定第一用户终端101优先发送数据。在DRX周期的160-640ms期间，第二用户终端102可以根据DRX机制在160-640ms期间从160ms开始的配置时间段(如160ms-180ms或160-200ms)开启持续允许发送定时器，第一用户终端101可以根据DRX机制在160-640ms期间从160ms开始的配置时间段(如160ms-180ms或160-200ms)开启持续监听定时器，以确定第二用户终端102优先发送数据。
可选地，所述方法还包括：如果向第一用户终端101进行数据调度或传输，则在预设的间隔时间后接收HARQ反馈。
请参阅图18，本公开还提供了一种边链路非连续发送装置1800，应用于第二用户终端102，需要说明的是，本公开所提供的边链路非连续发送装置1800，其基本原理及产生的技术效果和上述提供的边链路非连续发送方法的实施例相同，为简要描述，本实施例部分未提及之处，可参考上述提供的边链路非连续发送方法的实施例中相应内容。所述装置1800包括：

另外，对于DRX机制的配置方式，可以是第二用户终端102将业务参数、省电需求上报到基站103，基站103根据业务参数、省电需求生成DRX机制数据，然后第二用户终端102接收基站103下发的DRX机制数据并配置，第一用户终端101再通过边链路接收第二用户终端102发送的机制数据并配置；另外，对DRX机制的配置方式，还可以是第二用户终端102根据业务参数、省电需求直接生成DRX机制数据并配置，然后将DRX机制数据发送至第一用户终端101。当然地，对于DRX机制的配置方式不仅仅限于上述的两种，在此仅仅是举例说明。
