具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
上下行***中，UE只有在DRX Cycle中On Duration(激活期)的时间段内才侦听物理下行控制信道(Physical Downlink Control Channel，PDCCH)PDCCH，在DRX Cycle中的剩余时间段内可以进入休眠状态，DRX Cycle是周期性的，如图1所示。网络可以只配置一级DRX Cycle或配置两级DRX Cycle，包括Long DRX Cycle(长DRX周期)和Short DRX Cycle(短DRX周期)。图1为只有一级DRX Cycle的情况，在只配置一级DRX Cycle的情况下，DRX Cycle指Long DRX Cycle，即网络只配置Long DRX Cycle。
本申请实施例的技术方案可以应用于设备到设备(Device to Device，D2D)、车辆到车辆(vehicle to vehicle，V2V)、车辆到其他终端(Vehicle to Everything，V2X)等所有通过侧行链路(Sidelink，SL)传输技术实现的通信***中，SL传输技术与传统的蜂窝***中通信数据通过基站接收或者发送的方式不同。这种，设备到设备直接通信的方式具有更高的频谱效率以及更低的传输时延。关于设备到设备的通信，3GPP定义了两种传输模式：模式A和模式B。
模式A(如图2所示)：设备1和设备2的传输资源是由基站分配的，两个设备根据基站分配的资源在侧行链路上进行数据的传输；基站可以为设备分配单次传输的资源，也可以为设备分配半静态传输的资源。
模式B(如图3所示)：两个设备之间自行在资源池中选取一个资源进行数据的传输。具体的，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。
上述侦听的方式是指，设备根据过去一段时间内的资源侦听(包括解码其他设备发送的第一侧行控制信息以及测量SL-RSRP)，排除资源选择窗内的对应资源，从未被排除的剩余资源中选择资源进行传输。
在SL中，发送端配置DRX pattern(图案)给接收端。假设一个接收端与多个发送端之间存在单播或组播的业务，多个发送端配置不同的DRX pattern给同一个接收端，很有可能导致接收端一直处于监听状态无法休眠。如图4所示，UE A和UE B同时与UE C之间存在单播连接，UE A与UE B互相并不知道对方的存在，各自配置DRX Pattern给UE C，记为DRX Pattern 1(图案1)和DRX Pattern 2(图案2)。如果DRX Pattern 1与DRX Pattern 2是正交的(如图5所示)，那么UE C则一直处于On duration状态，一直处于监听物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)和/或物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)的状态，无法休眠省电，耗电较高。
应理解，本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请实施例提供了一种侧行链路的参数配置方法，应用于用户设备，且该设备可以为任意一种通过侧行链路进行通信的用户设备，为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
本发明实施例提供了一种侧行链路的参数配置方法，应用于第一用户设备，图6为本申请实施例中侧行链路的参数配置方法的第一流程示意图，如图6所示，包括：
步骤101：根据预设的配置规则，确定所述第一用户设备的第一DRX配置；
需要说明的是，预设的配置规则用于限定第一用户设备的DRX配置信息的选择范围，通过预设的配置规则来预先规划DRX配置范围，将可选择的DRX配置限定在较小的范围。如此，第一用户设备在作为接收端对其他用户设备进行非连续接收时，能够在较小的DRX配置范围内选择第一DRX配置，避免不同用户设备为第一用户设备配置不同DRX配置，造成第一用户设备持续处于监听状态无法休眠，保证第一用户设备有足够的休眠期，从而节省第一用户设备的能耗。
实际应用中，预设的配置规则可以为任意一种限定DRX配置选择范围的规则。
在一些实施例中，所述根据预设的配置规则，确定所述第一用户设备的第一DRX配置，包括：确定所述第一用户设备建议的DRX配置；根据所述建议的DRX配置确定所述第一用户设备的第一DRX配置。
这里，预设的配置规则为第二用户设备(也可称为UE2)根据第一用户设备(也可称为UE1)建议的DRX配置生成第一DRX配置，第二用户设备发送第一DRX配置给第一用户设备，第一用户设备根据第一DRX配置进行非连续接收。第一用户设备建议的DRX配置可以是网络设备为第一用户设备配置或预配置，或者建议的DRX配置取决于第一用户设备实现，比如，第一用户设备与其他用户设备连接时，根据其他连接对应的DRX配置得到的建议的DRX配置。
需要说明的是，第一用户设备作为接收端，第二用户设备作为发送端，接收端可以对多个发送端的数据进行非连续接收，即第一用户设备对应一个或多个第二用户设备，每个第一用户设备与第二用户设备间的连接对应的DRX配置均可以采用本申请实施例提供的参数配置方法来确定。
在另一些实施例中，所述根据预设的配置规则，确定所述第一用户设备的第一DRX配置，包括：接收所述第二用户设备根据地理位置信息或者所在小区信息确定的所述第一DRX配置。
这里，预设的配置规则为第二用户设备根据自身所在地理位置或所在小区确定第一DRX配置。实际应用中，网络可以预先对地理位置进行划分得到多个地理区域(ZONE)，再为每个地理区域配置一个或多个DRX配置，根据第二用户设备的地理位置判断处于哪个地理区域(用ZONE或ZONE ID表示)，再根据ZONE或者ZONE ID(地理区域标识)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为第一DRX配置。网络可以预先对小区进行划分得到多个小区组(Cell Group)，再为每个小区组配置一个或多个DRX配置，根据第二用户设备的所在小区信息判断处于哪个小区组(用Cell Group或Cell Group ID表示)，再根据Cell Group或Cell Group ID(小区组标识)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为第一DRX配置。网络也可以直接为某个小区配置一个或多个DRX配置，第二用户设备根据所在cell或者cell ID(小区ID)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为第一DRX配置。
这样，通过预设的配置规则来预先规划DRX配置范围，将可选择的DRX配置限定在较小的范围。第一用户设备在作为接收端对其他用户设备进行非连续接收时，能够在较小的DRX配置范围内选择第一DRX配置，避免不同用户设备为第一用户设备配置不同DRX配置，造成第一用户设备持续处于监听状态无法休眠，保证第一用户设备有足够的休眠期，从而节省第一用户设备的能耗。
步骤102：根据所述第一DRX配置对第二用户设备发送的数据进行非连续接收。
在一些实施例中，DRX配置(包括本申请实施例中建议的DRX配置、第一DRX配置、第二DRX配置和其他DRX配置)包括以下至少一项参数：第一参数、第二参数、第三参数、第四参数、第五参数、第六参数；
其中，所述第一参数用于指示第一时间长度，所述第一时间长度为在DRX周期中所述第一用户设备监听物理侧行控制信道PSCCH和/或物理侧行共享信道PSSCH的时间长度；
所述第二参数用于指示第二时间长度，所述第二时间长度为所述第一用户设备监听到PSCCH和/或PSSCH后，还需继续监听PSCCH和/或PSSCH的时间长度；
所述第三参数用于指示第三时间长度和/或第一偏移量，所述第三时间长度为长DRX周期的时间长度，第一偏移量是相对于时域参考点1的时间偏移量；
所述第四参数用于指示第二偏移量，该第二偏移量为长DRX周期和/或短DRX周期在时隙级别的偏移量；
所述第五参数用于指示第四时间长度，所述第四时间长度为短DRX周期的时间长度；
所述第六参数用于指示第一周期数目，所述第一用户设备在所述第一周期数目指示的短DRX周 期中没有监听到PSCCH和/或PSSCH，准备进入长DRX周期。
示例性地，第一参数(drx-onDurationTimer)：用于指示On duration状态的时间长度。如果配置了两级DRX Cycle，On duration状态在两级DRX Cycle中的时间长度是一样的。无论在Long DRX Cycle还是Short DRX Cycle中，都是先包括On duration状态，之后是休眠状态。该参数以1/32毫秒为单位，或以毫秒为单位。
第二参数(drx-InactivityTimer)：用于指示UE收到PSCCH和/或PSSCH后还应继续监听上下行调度或传输的时间长度。假设UE在On duration时间段的最后一个时隙监听到PSCCH和/或PSSCH，在下一个时隙UE将进入休眠状态。如果该PSCCH和/或PSSCH调度的数据或指示的重传没有在当前时隙或没有在当前时隙传输完成，则UE进入休眠后将无法接收数据。因此，UE应在监听到PSCCH和/或PSSCH后继续等待一段时间再进入休眠状态(即继续监听上下行调度或传输)。这段时间长度即为该参数所指示的时间长度。该参数单位为毫秒。
第三参数(drx-LongCycleStartOffset)：用于指示Long DRX Cycle的时间长度和相对于时域参考点1的偏移记为drxStartOffset。可选的，上述时域参考点1为SFN 0或SFN 0的起始边界或SFN 0中的第一个时隙或SFN 0中的第一个子帧。drxStartOffset用于确定Long DRX Cycle和/或Short DRX Cycle的时域起始位置。这两个参数的单位为毫秒。
第四参数(drx-SlotOffset)：用于指示Long DRX Cycle和/或Short DRX Cycle在时隙级别的偏移。因为上述几个参数的单位都是毫秒，在NR中1毫秒(一个子帧)可以等于若干个时隙。这与子载波间隔相关，例如子载波间隔是15kHz/30kHz/60kHz/120kHz时，一毫秒对应1/2/4/8个时隙。为了描述Long DRX Cycle和/或Short DRX Cycle的起始位置到底是在哪一个时隙，NR中引入了该参数。该参数的单位为1/32毫秒。
第五参数(drx-ShortCycle)：用于指示Short DRX Cycle的时间长度。该参数单位为毫秒。需要说明的是第五参数是一项可选的配置参数。
第六参数(drx-ShortCycleTimer)：用于指示当UE在多少个Short DRX Cycle中没有监听到PSCCH和/或PSSCH就准备进入Long DRX Cycle。需要说明的是第六参数是一项可选的配置参数。
下面用一个例子来说明上述DRX配置的在侧行链路***中的工作机制。
假设子载波间隔为15kHz，一个子帧等于一毫秒，一个子帧中只包含一个时隙。
DRX配置参数依次为：drx-onDurationTimer：2ms，drx-InactivityTimer：2ms，drx-LongCycleStartOffset：Long DRX cycle为10ms和drxStartOffset为1ms，drx-SlotOffset：0ms，drx-ShortCycle：5ms，drx-ShortCycleTimer：2。
图7为本申请实施例中DRX配置的示意图，如图7所示，SFN(System Frame Number)为***帧号，On Duration Timer为On Duration定时器用于对第一参数中的第一时间长度进行定时，Inactivity Timer为Inactivity定时器用于对第二参数中的第二时间长度进行定时，PSCCH和/或PSSCH表示在On duration状态进行PSCCH监听，或者PSSCH监听，或者PSCCH和PSSCH监听。具体地，无限帧0子帧1记为(0，1)，在(0，1)时UE(指第一用户设备)满足进入Long DRX Cycle的条件，因此(0，1)(0，2)为On duration状态，UE在(0，2)侦听到PSCCH和/或PSSCH，启动Inactivity定时器，因此在(0，3)和(0，4)继续监听PSCCH和/或PSSCH。在Inactivity定时器超时后，UE将首先准备进入短DRX周期(Short DRX Cycle，SDC)。在(0,6)，UE满足进入Short DRX Cycle的条件，此后多次进入Short DRX Cycle。由于drx-ShortCycleTimer为2，UE在连续两个Short DRX cycle均未监听到PSCCH和/或PSSCH(即从(0，6)到(1，5))，UE将准备进入长DRX周期(Long DRX Cycle，LDC)。在(2，1)UE满足进入Long DRX Cycle的条件，在该Cycle中未侦听到PSCCH和/或PSSCH。在(3，1)再次进入Long DRX Cycle，开始On duration状态，在(3，1)监听到PSCCH和/或PSSCH，再次开始Inactivity定时器以及将选择进入Short DRX Cycle。
在一些实施例中，上述满足进入Long DRX Cycle条件为，[SFN*10+子帧号]mod(Long DRX Cycle的时间长度)＝drxStartOffset。或者说Long DRX Cycle的周期性的起始子帧位置为[SFN*10+子帧号]mod(Long DRX Cycle的时间长度)＝drxStartOffset。例如图7中，在子帧(0，1)(1，1)(2，1)(3,1)UE可以进入Long DRX Cycle。
上述满足进入Short DRX Cycle条件为，[SFN*10+子帧号]mod(Short DRX Cycle的时间长度)＝drxStartOffset mod(Short DRX Cycle的时间长度)。或者说Short DRX Cycle的周期性的起始子帧位置为[SFN*10+子帧号]mod(Short DRX Cycle的时间长度)＝drxStartOffset mod(Short DRX Cycle的时间长度)。例如图7中，在子帧(0，1)(0，6)(1，1)(1，6)(2，1)(2，6)(3，1)(3，6)UE可以进入Short DRX Cycle。
可选的，具体时隙粒度的起始位置可以在子帧起始位置确定的基础上，根据上述配置参数drx-SlotOffset进行偏移。
采用上述方案，通过预设的配置规则来预先规划DRX配置范围，将可选择的DRX配置限定在较小的范围，第一用户设备根据预设的配置规则确定的第一DRX配置，能够解决不同用户设备为第一用户设备配置不同DRX配置的问题，避免第一用户设备一直处于On duration状态，节省能耗。
下面对本申请实施例中如何确定第一DRX配置进行进一步的举例说明，图8为本申请实施例中侧行链路的参数配置方法的第二流程示意图，如图8所示，包括：
步骤201：确定所述第一用户设备建议的DRX配置；
这里，预设的配置规则为第二用户设备(也可称为UE2)根据第一用户设备(也可称为UE1)建议的DRX配置生成配置应答，第二用户设备发送配置应答给第一用户设备，第一用户设备根据第一DRX配置进行非连续接收。
具体地，确定所述第一用户设备建议的DRX配置至少包括以下三种方式。
方式1：所述确定所述第一用户设备建议的DRX配置，包括：当所述第一用户设备与至少一个其他用户设备存在至少一个连接，根据所述至少一个连接对应的至少一个DRX配置，确定所述建议的DRX配置。
也就是说，第一用户设备在为第二用户设备确定建议的DRX配置时，可以将至少一个连接对应的至少一个DRX配置作为参考来确定。
在一些实施例中，所述根据所述至少一个连接对应的至少一个DRX配置，确定所述建议的DRX配置，包括：当存在一个连接时，将对应的一个DRX配置的目标参数作为所述建议的DRX配置的目标参数；当存在至少两个连接时，将对应的至少两个DRX配置中的一个DRX配置的目标参数作为所述建议的DRX配置的目标参数；或者，当存在至少两个连接时，根据对应的至少两个DRX配置中的至少两个目标参数，确定所述建议的DRX配置中的目标参数。
也就是说，不同的连接数量对应不同的确定方法，当存在一个连接时也就只存在一个参考DRX配置，根据一个参考DRX配置中的目标参数，确定建议DRX配置中的目标参数，这里，目标参数DRX配置中的任意一个参数，比如，目标参数为第一参数、第二参数、第三参数、第四参数、第五参数或第六参数。
当存在两个以上连接时，将至少两个DRX配置中的一个目标参数作为建议的DRX配置的目标参数；或者，根据至少两个DRX配置中的两个或多个目标参数来确定建议的DRX配置中的目标参数。示例性地，可以选择两个DRX配置中任意或特定DRX配置中的目标参数。
在一些实施例中，所述根据至少两个DRX配置中的至少两个目标参数，确定所述建议的DRX配置中的目标参数，包括：
将所述至少两个目标参数的最大值，作为所述建议的DRX配置中的目标参数；
或者，将所述至少两个目标参数的最小值，作为所述建议的DRX配置中的目标参数；
或者，将所述至少两个目标参数的平均值，作为所述建议的DRX配置中的目标参数；
或者，将所述至少两个目标参数中具有最多数量的一个参数，作为所述建议的DRX配置中的目标参数；
或者，将所述至少两个目标参数的最大公约数，作为所述建议的DRX配置中的目标参数；
或者，将所述至少两个目标参数的最小公倍数，作为所述建议的DRX配置中的目标参数。
在一些实施例中，DRX配置(包括本申请实施例中建议的DRX配置、第一DRX配置、第二DRX配置和其他DRX配置)包括以下至少一项参数：第一参数、第二参数、第三参数、第四参数、第五参数、第六参数；
其中，所述第一参数用于指示第一时间长度，所述第一时间长度为在DRX周期中所述第一用户设备监听PSCCH和/或PSSCH的时间长度；
所述第二参数用于指示第二时间长度，所述第二时间长度为所述第一用户设备监听到PSCCH和/或PSSCH后，还需继续监听PSCCH和/或PSSCH的时间长度；
所述第三参数用于指示第三时间长度和/或第一偏移量，所述第三时间长度为长DRX周期的时间长度，第一偏移量是相对于时域参考点1的时间偏移量；
所述第四参数用于指示第二偏移量，该第二偏移量为长DRX周期和/或短DRX周期在时隙级别的偏移量；
所述第五参数用于指示第四时间长度，所述第四时间长度为短DRX周期的时间长度；
所述第六参数用于指示第一周期数目，所述第一用户设备在所述第一周期数目指示的短DRX周 期中没有监听到PSCCH和/或PSSCH，准备进入长DRX周期。
这里，确定目标参数的方法也就是确定目标参数中时间长度或偏移量的方法。
具体地，在确定第一参数时，该第一时间长度可以取决于网络配置或预配置或取决于UE实现或为标准规定的预设值。
可选的，当UE 1已经存在一个和其他UE的单播或组播连接时，记为连接1。该第一时间长度为，连接1对应的DRX配置指示的第一时间长度。
可选的，当UE 1已经存在多个和其他UE的单播或组播连接时，记为连接1-N。该第一时间长度为，连接1-N中的其中一个连接对应的DRX配置指示的第一时间长度。或者该第一时间长度为，连接1-N中多个连接对应的DRX配置指示的第一时间长度的最大值或最小值或平均值或指示最多的值或最大公约数或最小公倍数。连接1-N可以部分是单播部分是组播。
在确定第二参数时，第二时间长度可以取决于网络配置或预配置或取决于UE实现或为标准规定的预设值。

在确定第三参数时，上述时域参考点1为SFN 0或SFN 0的起始边界或SFN 0中的第一个时隙或SFN 0中的第一个子帧。上述第一偏移量用于确定长DRX周期和/或短DRX周期的时域起始位置。

可选的，第一偏移量可以取决于网络配置或预配置或取决于UE实现或为标准规定的预设值。可选的，第一偏移量为0。可选的，当UE 1已经存在一个和其他UE的单播或组播连接时，记为连接1。该第一偏移量为，连接1对应的DRX配置指示的第一偏移量。
可选的，当UE 1已经存在多个和其他UE的单播或组播连接时，记为连接1-N。该第一偏移量为，连接1-N中的其中一个连接对应的DRX配置指示的第一偏移量。或该第一偏移量为，连接1-N中多个连接对应的DRX配置指示的第一偏移量的最大值或最小值或平均值或指示最多的值。连接1-N可以部分是单播部分是组播。
在确定第四参数时，第二偏移量可以取决于网络配置或预配置或取决于UE实现或为标准规定的预设值。可选的，第二偏移量为0。可选的，当UE 1已经存在一个和其他UE的单播或组播连接时，记为连接1。该第二偏移量为，连接1对应的DRX配置指示的第二偏移量。
可选的，当UE 1已经存在多个和其他UE的单播或组播连接时，记为连接1-N。该第二偏移量为，连接1-N中的其中一个连接对应的DRX配置指示的第二偏移量。或该第二偏移量为，连接1-N中多个连接对应的DRX配置指示的第二偏移量的最大值或最小值或平均值或指示最多的值。连接1-N可以部分是单播部分是组播。
假设子载波间隔是30kHz，一个子帧包含两个时隙，根据第三参数确定的长DRX周期的起始位置为子帧5，子帧10，子帧15。如果第四参数指示的值长度等于一个时隙，则长DRX周期的起始位置为子帧5中的第二个时隙，子帧10中的第二个时隙，子帧15中的第二个时隙。
在确定第五参数时，第四时间长度可以取决于网络配置或预配置或取决于UE实现或为标准规定的预设值。
可选的，当UE 1已经存在一个和其他UE的单播或组播连接时，记为连接1，且连接1对应的DRX配置指示了第四时间长度。该第四时间长度为，连接1对应的DRX配置指示的第四时间长度。示例性地，单播或组播连接指PC5-RRC连接。
可选的，当UE 1已经存在多个和其他UE的单播或组播连接时，记为连接1-N。该第四时间长 度为，连接1-N中的其中一个连接对应的DRX配置指示的第四时间长度。或该第四时间长度为，连接1-N中多个连接对应的DRX配置指示的第四时间长度的最大值或最小值或平均值或指示最多的值或最大公约数或最小公倍数。连接1-N可以部分是单播部分是组播。
在确定第五参数时，第一周期数目可以取决于网络配置或预配置或取决于UE实现或为标准规定的预设值。可选的，该第一周期数目为0。可选的，当UE 1已经存在一个和其他UE的单播或组播连接时，记为连接1，且连接1对应的DRX配置指示了第一周期数目。该第一周期数目为，连接1对应的DRX配置指示的第一周期数目。
可选的，当UE 1已经存在多个和其他UE的单播或组播连接时，记为连接1-N。该第一周期数目为，连接1-N中的其中一个连接对应的DRX配置指示的第一周期数目。或该第一周期数目为，连接1-N中多个连接对应的DRX配置指示的第一周期数目的最大值或最小值或平均值或指示最多的值。连接1-N可以部分是单播部分是组播。
方式2：所述确定所述第一用户设备建议的DRX配置，包括：根据网络设备配置或预配置，确定所述建议的DRX配置。
具体地，根据网络周期性配置或非周期性配置确定建议的DRX配置，比如，针对上述网络预配置可以是，用户设备出厂之前固化在芯片的DRX配置作为建议的DRX配置，或者UE在基站覆盖范围内时网络UE配置一个DRX配置，若UE移动到无网络覆盖则UE还是沿用之前基站配置的作为建议的DRX配置。或者根据第一用户设备实现确定建议的DRX配置，第一用户设备根据具体的通信条件自行配置。
方式3：所述确定所述第一用户设备建议的DRX配置，包括：根据所述第一用户设备的地理位置信息或者所在小区信息，确定所述建议的DRX配置。
这样，通过预设的配置规则来预先规划DRX配置范围，将可选择的DRX配置限定在较小的范围。第一用户设备在作为接收端对其他用户设备进行非连续接收时，能够在较小的DRX配置范围内选择第一DRX配置，避免不同用户设备为第一用户设备配置不同DRX配置，造成第一用户设备持续处于监听状态无法休眠，保证第一用户设备有足够的休眠期，从而节省第一用户设备的能耗。
在一些实施例中，所述根据所述第一用户设备的地理位置信息或者所在小区信息，确定所述建议的DRX配置，包括：根据所述第一用户设备的地理位置信息，在第一对应关系中查找对应的至少一个DRX配置，从所述至少一个DRX配置确定所述建议的DRX配置；或者，根据所述第一用户设备所在的小区信息，在第二对应关系中查找对应的至少一个DRX配置，从所述至少一个DRX配置确定所述建议的DRX配置；其中，所述第一对应关系中包括地理位置信息与DRX配置的对应关系；所述第二对应关系中包括小区信息与DRX配置的对应关系。
在一些实施例中，所述从所述至少一个DRX配置确定所述建议的DRX配置，包括：根据接收业务的业务类型或业务周期或业务优先级，从所述至少一个DRX配置选择一个DRX配置作为所述建议的DRX配置；或者，从所述至少一个DRX配置随机选择一个DRX配置作为所述建议的DRX配置。
实际应用中，网络可以预先对地理位置进行划分得到多个地理区域(ZONE)，再为每个地理区域配置一个或多个DRX配置，根据第一用户设备的地理位置判断处于哪个地理区域(用ZONE或ZONE ID表示)，再根据ZONE或者ZONE ID(地理区域标识)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为建议的DRX配置。网络可以预先对小区进行划分得到多个小区组(Cell Group)，再为每个小区组配置一个或多个DRX配置，根据第一用户设备的所在小区信息判断处于哪个小区组(用Cell Group或Cell Group ID表示)，再根据Cell Group或Cell Group ID(小区组标识)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为建议的DRX配置。网络也可以直接为某个小区配置一个或多个DRX配置，第一用户设备根据所在cell或者cell ID(小区ID)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为建议的DRX配置。
示例性地，UE 1根据第一对应关系确定一个或多个DRX配置，上述第一对应关系包括地理区域ZONE或ZONE ID与一个或多个DRX配置之间的对应关系。第二对应关系包括小区或小区ID与一个或多个DRX配置之间的对应关系。上述DRX配置包括第一至第六参数中的一个或多个。第一对应关系以及第二对应关系网络配置或预配置。
进一步地，UE 1首先根据定位***判断自身地理位置，再根据自身地理位置判断处于哪个地理区域ZONE，再根据ZONE或ZONE ID和第一对应关系确定一个或多个DRX配置。如果UE 1确定了多个DRX配置，UE 1从中确定一个DRX配置。例如，UE 1从中随机确定一个DRX配置，或 UE 1根据收到的业务的类型(如周期性业务或非周期业务等)或收到的业务的周期或收到的业务的优先级，从中确定一个DRX配置。上述地理区域的划分信息，示例性地，每个ZONE的长和宽，经度和纬度绝对或相对偏移，精度和纬度参考点等，由网络配置或预配置。

步骤302：接收所述第二用户设备的配置应答；
在一些实施例中，所述接收所述第二用户设备的配置应答，包括：接收所述第二用户设备根据所述建议的DRX配置和/或第二DRX配置生成的第一DRX配置。
具体地，所述接收所述第二用户设备根据所述建议的DRX配置和/或第二DRX配置生成的第一DRX配置，包括：所述第二用户设备确定所述建议的DRX配置可用，接收所述第二用户设备根据所述建议的DRX配置生成的第一DRX配置；或者，所述第二用户设备确定所述建议的DRX配置不可用，接收所述第二用户设备根据所述第二DRX配置生成的第一DRX配置；或者，接收所述第二用户设备根据所述建议的DRX配置和第二DRX配置生成的第一DRX配置。
需要说明的时，根据建议的DRX配置和第二DRX配置生成的第一DRX配置时，可以与建议的DRX配置是否可用有关，也可以无关。也就是说，第二用户设备可以直接根据二者生成第一DRX配置，或者确定建议的DRX配置可用时，根据所述建议的DRX配置和第二DRX配置生成的第一DRX配置。
在一些实施例中，所述第二DRX配置由网络设备配置或预配置。
在一些实施例中，第二用户设备判断建议的DRX配置是否可用的方法可以为：判断建议的DRX配置的长或短DRX周期长度是否可以满足第二用户设备的业务需求。比如建议的DRX配置指示的长DRX周期或短DRX周期是否小于业务的周期，如果小于则满足，否则为不满足，或小于等于为满足，否则为不满足。
在一些实施例中，发送一个建议的DRX配置给所述第二用户设备时，所述接收所述第二用户设备的配置应答，包括：所述第二用户设备确定所述建议的DRX配置可用时，接收所述第二用户设备的第一应答；其中，所述第一应答用于指示所述建议的DRX配置可用。比如，第一应答包括用于指示建议的DRX配置可用的标识信息，或者不可用的标识信息。

步骤303：根据所述配置应答确定所述第一DRX配置。
具体地，若配置应答为第一DRX配置，则步骤302和步骤303可以替换为接收第二用户设备发送的第一DRX配置。
若配置应答为第一应答，根据第一应答确定建议的DRX配置可用，则建议的DRX配置即为第一DRX配置，若不可用，则利用可以网络配置或预配置的DRX配置作为第一DRX配置，或根据取决于第一用户设备现或为标准规定得到第一DRX配置。
若配置为第二应答，若第二应答中的包含索引信息，则根据索引信息确定第一DRX配置，若不包含，利用可以网络配置或预配置的DRX配置作为第一DRX配置，或根据取决于第一用户设备现或为标准规定得到第一DRX配置。
示例性地，配置应答可以通过PC5无线资源控制(PC5Radio Resource Control，PC5RRC)连接或MAC控制单元MAC Control Element，MAC CE)或第二侧行控制信息或第一侧行控制信息或物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)承载，将配置应答发送给第一用户设备。
步骤203：根据所述第一DRX配置对第二用户设备发送的数据进行非连续接收。
在一些实施例中，DRX配置(包括本申请实施例中建议的DRX配置、第一DRX配置、第二DRX配置和其他DRX配置)包括以下至少一项参数：第一参数、第二参数、第三参数、第四参数、第五参数、第六参数；

具体的实现过程可以参考图7及其对应的文字部分，这里不在赘述。
采用上述技术方案，第一用户设备可以根据建议的DRX配置，确定第一DRX配置，这样第一用户设备作为接收端对不同第二用户设备的数据进行非连续接收时，将可选择的DRX配置限定在较小的范围，能够解决不同用户设备为第一用户设备配置不同DRX配置的问题，避免第一用户设备一直处于On duration状态，节省能耗。
图10为NR侧行链路物理层结构的示意图，如图10所示，物理层包括PSCCH和PSSCH，其中PSCCH用于传输第一侧行控制信息，PSSCH用于承载数据和第二侧行控制信息，PSCCH和PSSCH在同一时隙中发送。对于第一侧行控制信息，其主要包含资源侦听相关的域，方便其他UE解码后获取该第一侧行控制信息所指示的时频资源，从而在资源选择过程中排除对应资源，避免资源碰撞。对于第二侧行控制信息，主要包括数据解调相关的域，方便其他UE解调对应PSSCH中的数据。
实际应用中，UE 2通过PC5-RRC连接或MAC CE或第二侧行控制信息或第一侧行控制信息或PSFCH将配置应答发送给UE 1。UE 1根据接收到的DRX配置进行非连续接收。
UE 1与其他UE单播或组播连接，且UE1作为接收端。实际应用中单播或组播连接为PC5RRC连接。
在一些实施例中，UE1向UE2发送建议的DRX配置时，建议的DRX配置可以通过PC5-RRC连接或MAC CE或第二侧行控制信息承载。
图11为本申请实施例中侧行链路的参数配置方法的第三流程示意图，如图11所示，包括：
步骤401：接收所述第二用户设备根据地理位置信息或者所在小区信息确定的所述第一DRX配置；
在一些实施例中，所述接收所述第二用户设备根据地理位置信息或者所在小区信息确定的所述第一DRX配置，包括：接收所述第二用户设备根据地理位置信息在第一对应关系中查找到的所述第一DRX配置；或者，接收所述第二用户设备根据所在的小区信息在第二对应关系中查找到的所述第一DRX配置；其中，所述第一对应关系中包括地理位置信息与DRX配置的对应关系；所述第二对应关系中包括小区信息与DRX配置的对应关系。
实际应用中，这里，预设的配置规则为第二用户设备根据自身所在地理位置或所在小区确定第一DRX配置。实际应用中，网络可以预先对地理位置进行划分得到多个地理区域(ZONE)，再为每个地理区域配置一个或多个DRX配置，根据第二用户设备的地理位置判断处于哪个地理区域(用ZONE或ZONE ID表示)，再根据ZONE或者ZONE ID(地理区域标识)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为第一DRX配置。网络可以预先对小区 进行划分得到多个小区组(Cell Group)，再为每个小区组配置一个或多个DRX配置，根据第二用户设备的所在小区信息判断处于哪个小区组(用Cell Group或Cell Group ID表示)，再根据Cell Group或Cell Group ID(小区组标识)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为第一DRX配置。网络也可以直接为某个小区配置一个或多个DRX配置，第二用户设备根据所在cell或者cell ID(小区ID)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为第一DRX配置。
示例性地，UE 2根据第一对应关系确定一个或多个DRX配置，上述第一对应关系包括地理区域ZONE或ZONE ID与一个或多个DRX配置之间的对应关系。第二对应关系包括小区或小区ID与一个或多个DRX配置之间的对应关系。上述DRX配置包括第一至第六参数中的一个或多个。第一对应关系以及第二对应关系网络配置或预配置。
进一步地，UE 2首先根据定位***判断自身地理位置，再根据自身地理位置判断处于哪个地理区域ZONE,再根据ZONE或ZONE ID和第一对应关系确定一个或多个DRX配置。如果UE 2确定了多个DRX配置，UE 2从中确定一个DRX配置。例如，UE 2根据自身业务类型(周期性业务或非周期业务等)或业务周期或业务的优先级，从多个DRX配置中确定一个DRX配置，或者UE 2从中随机确定一个DRX配置。上述地理区域的划分信息，示例性地，每个ZONE的长和宽，经度和纬度绝对或相对偏移，精度和纬度参考点等，由网络配置或预配置。
UE 2根据所处小区或所处小区的ID和第二对应关系确定一个或多个DRX配置。如果UE 2确定了多个DRX配置，UE 2从中确定一个DRX配置。例如，UE 2根据自身业务类型(周期性业务或非周期业务等)或业务周期或业务的优先级，从多个DRX配置中确定一个DRX配置，或者UE 2从中随机确定一个DRX配置。
实际应用中，UE 2通过PC5RRC连接或MAC CE或第二侧行控制信息或第一侧行控制信息或侧行反馈信道PSFCH将确定的第一DRX配置发送给UE 1。UE 1根据接收到的第一DRX配置进行非连续接收。
步骤402：根据所述第一DRX配置对第二用户设备发送的数据进行非连续接收。
在一些实施例中，DRX配置(包括本申请实施例中建议的DRX配置、第一DRX配置、第二DRX配置和其他DRX配置)包括以下至少一项参数：第一参数、第二参数、第三参数、第四参数、第五参数、第六参数；
其中，所述第一参数用于指示第一时间长度，所述第一时间长度为在DRX周期中所述第一用户设备监听物理侧行控制信道PSCCH和/或物理侧行共享信道PSSCH的时间长度；
所述第二参数用于指示第二时间长度，所述第二时间长度为所述第一用户设备监听到PSCCH和/或PSSCH后，还需继续监听PSCCH和/或PSSCH的时间长度；
所述第三参数用于指示第三时间长度和/或第一偏移量，所述第三时间长度为长DRX周期的时间长度，第一偏移量是相对于时域参考点1的时间偏移量；
所述第四参数用于指示第二偏移量，该第二偏移量为长DRX周期和/或短DRX周期在时隙级别的偏移量；
所述第五参数用于指示第四时间长度，所述第四时间长度为短DRX周期的时间长度；
所述第六参数用于指示第一周期数目，所述第一用户设备在所述第一周期数目指示的短DRX周期中没有监听到PSCCH和/或PSSCH，准备进入长DRX周期。
具体的实现过程可以参考图7及其对应的文字部分，这里不在赘述。
采用上述技术方案，通过预先设置地理区域或小区与一个或多个DRX配置的对应关系，根据第二用户设备的地理位置信息或小区信息，确定第一DRX配置，这样处于同一地理区域或同一小区的第二用户设备为第一用户设备可以配置相同或相近的DRX配置，将可选择的DRX配置限定在较小的范围，能够解决不同用户设备为第一用户设备配置不同DRX配置的问题，避免第一用户设备一直处于On duration状态，节省能耗。
基于同一发明构思，本申请实施例还提供了另一种侧行链路的参数配置方法，应用于第二用户设备，图12为本申请实施例中侧行链路的参数配置方法的第四流程示意图，如图12所示，包括：
步骤501：根据预设的配置规则，确定第一用户设备的第一DRX配置，并生成配置应答；
需要说明的是，预设的配置规则用于限定第一用户设备的DRX配置信息的选择范围，通过预设的配置规则来预先规划DRX配置范围，将可选择的DRX配置限定在较小的范围。如此，第一用户设备在作为接收端对其他用户设备进行非连续接收时，能够在较小的DRX配置范围内选择第一DRX配置，避免不同用户设备为第一用户设备配置不同DRX配置，造成第一用户设备持续处于监听状态 无法休眠，保证第一用户设备有足够的休眠期，从而节省第一用户设备的能耗。
实际应用中，预设的配置规则可以为任意一种限定DRX配置选择范围的规则。
在一些实施例中，所述根据预设的配置规则，确定第一用户设备的第一DRX配置，并生成配置应答，包括：接收所述第一用户设备一个或多个建议的DRX配置；根据所述建议的DRX配置确定所述第一用户设备的第一DRX配置，并生成配置应答。
这里，预设的配置规则为第二用户设备(也可称为UE2)根据第一用户设备(也可称为UE1)建议的DRX配置生成第一DRX配置，第二用户设备发送配置应答给第一用户设备，第一用户设备根据第一DRX配置进行非连续接收。第一用户设备建议的DRX配置可以是网络设备为第一用户设备配置或预配置，或者建议的DRX配置取决于第一用户设备实现，比如，第一用户设备与其他用户设备连接时，根据其他连接对应的DRX配置得到的建议的DRX配置。
需要说明的是，第一用户设备作为接收端，第二用户设备作为发送端，接收端可以对多个发送端的数据进行非连续接收，即第一用户设备对应一个或多个第二用户设备，每个第一用户设备与第二用户设备间的连接对应的DRX配置均可以采用本申请实施例提供的参数配置方法来确定。
在一些实施例中，所述根据预设的配置规则，确定第一用户设备的第一DRX配置，并生成配置应答，包括：接收所述第一用户设备建议的DRX配置；发送所述建议的DRX配置给网络设备；接收所述网络设备下发的所述第一DRX配置；将所述第一DRX配置作为所述配置应答。
这里，预设的配置规则为第二用户设备将建议的DRX配置上报给网络设备，由网络设备根据建议的DRX配置确定第一DRX配置，或者由网络设备根据实际通信需求配置第一DRX配置。
示例性地，网络设备确定所述建议的DRX配置可用，根据所述建议的DRX配置生成第一DRX配置；或者，网络设备确定所述建议的DRX配置不可用，根据第二DRX配置生成第一DRX配置；或者，根据所述建议的DRX配置和第二DRX配置生成第一DRX配置；或者，根据第二DRX配置生成第一DRX配置。
在一些实施例中，所述根据预设的配置规则，确定第一用户设备的第一DRX配置，并生成配置应答，包括：根据所述第二用户设备的地理位置信息或者所在小区信息确定所述第一DRX配置；将所述第一DRX配置作为所述配置应答。
这里，预设的配置规则为第二用户设备根据自身所在地理位置或所在小区确定第一DRX配置。
这样，通过预设的配置规则来预先规划DRX配置范围，将可选择的DRX配置限定在较小的范围。第一用户设备在作为接收端对其他用户设备进行非连续接收时，能够在较小的DRX配置范围内选择第一DRX配置，避免不同用户设备为第一用户设备配置不同DRX配置，造成第一用户设备持续处于监听状态无法休眠，保证第一用户设备有足够的休眠期，从而节省第一用户设备的能耗。
步骤502：发送所述配置应答至所述第一用户设备，以使所述第一用户设备根据所述配置应答确定的所述第一DRX配置对第二用户设备发送的数据进行非连续接收。
在一些实施例中，DRX配置(包括本申请实施例中建议的DRX配置、第一DRX配置、第二DRX配置和其他DRX配置)包括以下至少一项参数：第一参数、第二参数、第三参数、第四参数、第五参数、第六参数；
其中，所述第一参数用于指示第一时间长度，所述第一时间长度为在DRX周期中所述第一用户设备监听物理侧行控制信道PSCCH和/或物理侧行共享信道PSSCH的时间长度；
所述第二参数用于指示第二时间长度，所述第二时间长度为所述第一用户设备监听到PSCCH和/或PSSCH后，还需继续监听PSCCH和/或PSSCH的时间长度；
所述第三参数用于指示第三时间长度和/或第一偏移量，所述第三时间长度为长DRX周期的时间长度，第一偏移量是相对于时域参考点1的时间偏移量；
所述第四参数用于指示第二偏移量，该第二偏移量为长DRX周期和/或短DRX周期在时隙级别的偏移量；
所述第五参数用于指示第四时间长度，所述第四时间长度为短DRX周期的时间长度；
所述第六参数用于指示第一周期数目，所述第一用户设备在所述第一周期数目指示的短DRX周期中没有监听到PSCCH和/或PSSCH，准备进入长DRX周期。
具体的实现过程可以参考图7及其对应的文字部分，这里不在赘述。
采用上述方案，通过预设的配置规则来预先规划DRX配置范围，将可选择的DRX配置限定在较小的范围，第二用户设备根据预设的配置规则确定的第一DRX配置，能够解决不同用户设备为第一用户设备配置不同DRX配置的问题，避免第一用户设备一直处于On duration状态，节省能耗。
下面对本申请实施例中如何确定第一DRX配置进行进一步的举例说明，图13为本申请实施例 中侧行链路的参数配置方法的第五流程示意图，如图13所示，包括：
步骤601：接收所述第一用户设备一个或多个建议的DRX配置；
需要说明的是，建议的DRX配置的生成方法可以参考上述第一用户设备对应的实施例，这里不再赘述。
步骤602：根据所述建议的DRX配置确定所述第一用户设备的第一DRX配置，并生成配置应答；
在一些实施例中，接收所述第一用户设备发送的一个建议的DRX配置时，所述根据所述建议的DRX配置确定所述第一用户设备的第一DRX配置，并生成配置应答，包括：根据所述建议的DRX配置和/或第二DRX配置生成第一DRX配置；将所述第一DRX配置作为所述配置应答。
具体地，所述根据所述建议的DRX配置和/或第二DRX配置生成第一DRX配置，包括：确定所述建议的DRX配置可用，根据所述建议的DRX配置生成第一DRX配置；或者，确定所述建议的DRX配置不可用，根据所述第二DRX配置生成第一DRX配置；或者，根据所述建议的DRX配置和第二DRX配置生成的第一DRX配置。
需要说明的时，根据建议的DRX配置和第二DRX配置生成的第一DRX配置时，可以与建议的DRX配置是否可用有关，也可以无关。也就是说，第二用户设备可以直接根据二者生成第一DRX配置，或者确定建议的DRX配置可用时，根据所述建议的DRX配置和第二DRX配置生成的第一DRX配置。
在一些实施例中，所述第二DRX配置由网络设备配置或预配置。
在一些实施例中，第二用户设备判断建议的DRX配置是否可用的方法可以为：判断建议的DRX配置的长或短DRX周期长度是否可以满足UE 2的业务需求。比如建议的DRX配置指示的长DRX周期或短DRX周期是否小于业务的周期，如果小于则满足，否则为不满足，或小于等于为满足，否则为不满足。
在另一些实施例中，接收所述第一用户设备发送的一个建议的DRX配置时，所述根据所述建议的DRX配置确定所述第一用户设备的第一DRX配置，并生成配置应答，包括：确定所述建议的DRX配置可用，生成第一应答；其中，所述第一应答用于指示所述建议的DRX配置可用；将所述第一应答作为所述配置应答。比如，第一应答包括用于指示建议的DRX配置可用的标识信息，或者不可用的标识信息。
在另一些实施例中，接收所述第一用户设备发送的多个建议的DRX配置时，所述根据所述建议的DRX配置确定所述第一用户设备的第一DRX配置，并生成配置应答，包括：从所述多个建议的DRX配置中确定一个目标DRX配置，生成第二应答；其中，所述第二应答用于指示所述多个建议的DRX配置中一个目标DRX配置；将所述第二应答作为所述配置应答。比如，第二应答包括目标DRX配置的索引信息，或者不包括任何索引信息。这里，目标DRX配置即为第一DRX配置。
步骤603：发送所述配置应答至所述第一用户设备。
本申请实施例中，第一用户设备在接收到配置应答后，第一用户设备根据所述配置应答确定的所述第一DRX配置对第二用户设备发送的数据进行非连续接收。
具体地，若配置应答为第一DRX配置，则步骤602可以替换为根据所述建议的DRX配置确定所述第一用户设备的第一DRX配置，步骤603可以替换为发送第一DRX配置至第一用户设备。
若配置应答为第一应答，根据第一应答确定建议的DRX配置可用，则建议的DRX配置即为第一DRX配置，若不可用，则利用可以网络配置或预配置的DRX配置作为第一DRX配置，或根据取决于第一用户设备现或为标准规定得到第一DRX配置。
若配置为第二应答，若第二应答中的包含索引信息，则根据索引信息确定第一DRX配置，若不包含，利用可以网络配置或预配置的DRX配置作为第一DRX配置，或根据取决于第一用户设备现或为标准规定得到第一DRX配置。
采用上述技术方案，第一用户设备向第二用户设备发送建议的DRX配置，第二用户设备根据建议的DRX配置确定第一DRX配置，这样可以将第二用户设备可选择的DRX配置限定在较小的范围，能够解决不同用户设备为第一用户设备配置不同DRX配置的问题，避免第一用户设备一直处于On duration状态，节省能耗。
图14为本申请实施例中侧行链路的参数配置方法的第六流程示意图，如图14所示，包括：
步骤701：根据所述第二用户设备的地理位置信息或者所在小区信息确定所述第一DRX配置；
在一些实施例中，所述根据所述第二用户设备的地理位置信息或者所在小区信息确定所述第一DRX配置，包括：根据地理位置信息在第一对应关系中查找对应的至少一个DRX配置，从所述至 少一个DRX配置确定所述第一DRX配置；或者，根据所在小区信息在第二对应关系中查找对应的至少一个DRX配置，从所述至少一个DRX配置确定所述第一DRX配置；其中，所述第一对应关系中包括地理位置信息与DRX配置的对应关系；所述第二对应关系中包括小区信息与DRX配置的对应关系。
在一些实施例中，所述从所述至少一个DRX配置确定所述第一DRX配置，包括：根据发送业务的业务类型或业务周期或业务优先级，从所述至少一个DRX配置选择一个DRX配置作为所述第一DRX配置；或者，从所述至少一个DRX配置随机选择一个DRX配置作为所述第一DRX配置。
实际应用中，网络可以预先对地理位置进行划分得到多个地理区域(ZONE)，再为每个地理区域配置一个或多个DRX配置，根据第二用户设备的地理位置判断处于哪个地理区域(用ZONE或ZONE ID表示)，再根据ZONE或者ZONE ID(地理区域标识)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为第一DRX配置。网络可以预先对小区进行划分得到多个小区组(Cell Group)，再为每个小区组配置一个或多个DRX配置，根据第二用户设备的所在小区信息判断处于哪个小区组(用Cell Group或Cell Group ID表示)，再根据Cell Group或Cell Group ID(小区组标识)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为第一DRX配置。网络也可以直接为某个小区配置一个或多个DRX配置，第二用户设备根据所在cell或者cell ID(小区ID)确定对应的一个或多个DRX配置，若确定多个DRX配置，则从多个中确定一个作为第一DRX配置。
示例性地，UE 2根据第一对应关系确定一个或多个DRX配置，上述第一对应关系包括地理区域ZONE或ZONE ID与一个或多个DRX配置之间的对应关系。第二对应关系包括小区或小区ID与一个或多个DRX配置之间的对应关系。上述DRX配置包括第一至第六参数中的一个或多个。第一对应关系以及第二对应关系网络配置或预配置。
进一步地，UE 2首先根据定位***判断自身地理位置，再根据自身地理位置判断处于哪个地理区域ZONE,再根据ZONE或ZONE ID和第一对应关系确定一个或多个DRX配置。如果UE 2确定了多个DRX配置，UE 2从中确定一个DRX配置。例如，UE 2根据自身业务类型(周期性业务或非周期业务等)或业务周期或业务的优先级，从多个DRX配置中确定一个DRX配置，或者UE 2从中随机确定一个DRX配置。上述地理区域的划分信息，示例性地，每个ZONE的长和宽，经度和纬度绝对或相对偏移，精度和纬度参考点等，由网络配置或预配置。
UE 2根据所处小区或所处小区的ID和第二对应关系确定一个或多个DRX配置。如果UE 2确定了多个DRX配置，UE 2从中确定一个DRX配置。例如，UE 2根据自身业务类型(周期性业务或非周期业务等)或业务周期或业务的优先级，从多个DRX配置中确定一个DRX配置，或者UE 2从中随机确定一个DRX配置。
实际应用中，UE 2通过PC5RRC连接或MAC CE或第二侧行控制信息或第一侧行控制信息或侧行反馈信道PSFCH将确定的DRX配置发送给UE 1。UE 1根据接收到的DRX配置进行非连续接收。
步骤702：将所述第一DRX配置作为配置应答；

本申请实施例中，第一用户设备在接收到配置应答后，第一用户设备根据所述配置应答确定的所述第一DRX配置对第二用户设备发送的数据进行非连续接收。
具体地，若配置应答为第一DRX配置，则步骤702和步骤703可以替换为发送第一DRX配置至所述第一用户设备。
采用上述技术方案，通过预先设置地理区域或小区与一个或多个DRX配置的对应关系，根据第二用户设备的地理位置信息或小区信息，确定第一DRX配置，这样处于同一地理区域或同一小区的第二用户设备为第一用户设备可以配置相同或相近的DRX配置，将可选择的DRX配置限定在较小的范围，能够解决不同用户设备为第一用户设备配置不同DRX配置的问题，避免第一用户设备一直处于On duration状态，节省能耗。
