本申请涉及通信技术领域，尤其涉及一种唤醒信号传输方法及通信***。
背景技术
为了节省终端设备的功耗，第三代合作伙伴计划(3rd generation partnership project，3GPP)协议所规定的新空口(new radio，NR)***在版本(release)15引入了非连续接收(discontinuous reception，DRX)机制。DRX机制是为处于无线资源控制(radio resource control，RRC)连接态的终端设备配置一个DRX周期，配置了DRX周期的终端设备在DRX激活时间内醒来监测物理下行控制信道(physical downlink control channel，PDCCH)，在DRX非激活时间内进入睡眠不监测PDCCH。
如果接入网设备没有下行数据要发送，那么接入网设备可以通知终端设备睡眠一个长DRX周期，而不是定期醒来监测一段时间PDCCH后再进入睡眠。因此，NR***在release 16引入了唤醒信号(wake-up signal，WUS)，配置了WUS的终端设备在开始长DRX周期之前醒来一段时间检查WUS，如果被告知无需唤醒，那么终端设备在下一个长DRX周期进入睡眠。NR***还在release 18引入了唤醒接收机(wake-up receiver，WUR)，配置了WUR接口的终端设备通过WUR链路或者主链路接收WUS，WUR链路的检查功耗低于主链路的睡眠功耗，WUR对终端设备的功耗节省增益显著。但是WUR需要采用通断键控(on-off-keying，OOK)、频移键控(frequency shift keying，FSK)等支持低功耗接收的调制方式，才能具有上述特征，而采用OOK、FSK等支持低功耗接收的调制方式传输WUS时，WUR链路的覆盖能力会比主链路差，部分边缘终端设备的WUR链路会超出接入网设备发送的WUS覆盖范围，此时要么终端设备定时切换到主链路收发数据，但会产生较大功耗，要么接入网设备增加发射功率，但不仅会产生较大开销，也容易干扰其他终端设备。
可见，现有的唤醒信号传输方法存在当终端设备的WUR链路超出接入网设备发送的WUS覆盖范围时，由于终端设备无法通过WUR链路接收WUS，将导致终端设备的功耗增加或者接入网设备的开销增加的问题。
发明内容
本申请实施例提供一种唤醒信号传输方法及通信***，用以解决现有的唤醒信号传输方法存在的当终端设备的WUR链路超出接入网设备发送的WUS覆盖范围时，将导致终端设备的功耗增加或者接入网设备的开销增加的问题。
第一方面，提供了一种唤醒信号传输方法，该方法可以由接入网设备执行，或者由设置在接入网设备中的用于实现接入网设备的功能的芯片执行，或者用于实现接入网设备的功能的其他部件执行，该方法包括：
接入网设备确定唤醒信号；其中，所述唤醒信号中携带第一指示信息；
所述接入网设备将所述唤醒信号发送给第一终端设备，以使所述第一终端设备基于所述唤醒信号确定是否将所述第一指示信息转发给第二终端设备。
在本申请实施例中，接入网设备可以在唤醒信号中增加第二终端设备的唤醒指示信息，接入网设备只需将唤醒信号发送给第一终端设备即可，第一终端设备再基于唤醒信号确定是否将第二终端设备的唤醒指示信息转发给第二终端设备。可见，通过本申请实施例提供的技术方案，第二终端设备的唤醒指示信息可以由第一终端设备转发给第二终端设备，无需接入网设备直接发送给第二终端设备，由此第二终端设备无需定时切换到主链路收发数据，减小了第二终端设备的功耗，接入网设备也无需增加发射功率，因此不仅减小了接入网设备和第二终端设备的开销，也不容易干扰其他终端设备。
在一种可能的实施方式中，接入网设备确定唤醒信号之前，还可以获取任一终端设备的终端类型信息和测量信息；其中，所述终端类型信息指示所述任一终端设备是否为功耗不敏感终端设备，所述测量信息指示所述任一终端设备的位置以及所述任一终端设备的唤醒接收机WUR链路和主链路的覆盖情况；基于所述终端类型信息和所述测量信息，确定所述第一终端设备和所述第二终端设备。
在本申请实施例中，接入网设备可以基于终端设备是否为功耗不敏感终端设备、终端设备的位置以及终端设备的唤醒接收机WUR链路和主链路的覆盖情况，确定唤醒信号传输中的转发设备(即第一终端设备)和目标设备(即第二终端设备)，使得第二终端设备的唤醒指示信息可以由第一终端设备转发给第二终端设备，无需接入网设备直接发送给第二终端设备，由此第二终端设备无需定时切换到主链路接收唤醒信号，减小了第二终端设备的功耗，接入网设备也无需增加发射功率，因此不仅减小了接入网设备和第二终端设备的开销，也不容易干扰其他终端设备。
在一种可能的实施方式中，所述第一终端设备可以为功耗不敏感终端设备，所述第一终端设备的WUR链路的覆盖测量结果不小于第一阈值，所述第一终端设备的主链路的覆盖测量结果不小于第二阈值。
在一种可能的实施方式中，所述第二终端设备的WUR链路的覆盖测量结果小于所述第一阈值，所述第二终端设备的主链路的覆盖测量结果不小于所述第二阈值，所述第二终端设备与所述第一终端设备的距离不大于第三阈值。
这样使得当第一终端设备的WUR链路未超出接入网设备发送的WUS覆盖范围，第二终端设备的WUR链路超出接入网设备发送的WUS覆盖范围时，接入网设备只需将第二终端设备的唤醒指示信息发送给WUR链路的覆盖测量结果不小于第一阈值的第一终端设备即可，第一终端设备再将第二终端设备的唤醒指示信息转发给与第一终端设备的距离不大于第三阈值的第二终端设备。由此第二终端设备无需定时切换到主链路收发数据，减小了第二终端设备的功耗，接入网设备也无需增加发射功率，因此不仅减小了接入网设备和第二终端设备的开销，也不容易干扰其他终端设备。
在一种可能的实施方式中，所述唤醒信号中还可以携带转发指示信息或者采用预定义的帧结构；其中，所述转发指示信息指示所述第一终端设备是否将所述第一指示信息转发 给所述第二终端设备，所述预定义的帧结构指示所述第一终端设备将所述第一指示信息转发给所述第二终端设备。
在一种可能的实施方式中，所述唤醒信号中还可以携带第二指示信息；所述转发指示信息可以指示所述第一终端设备是否将所述第一指示信息转发给所述第二终端设备，包括：
所述转发指示信息可以指示所述第一终端设备基于所述第二指示信息唤醒所述第一终端设备的主链路；或者，
所述转发指示信息还可以指示所述第一终端设备不基于所述第二指示信息唤醒所述第一终端设备的主链路，并将所述第一指示信息转发给所述第二终端设备。
在本申请实施例中，接入网设备可以在唤醒信号中增加转发指示信息和第二指示信息，转发指示信息可以指示第一终端设备是否基于第二指示信息唤醒第一终端设备的主链路，或者在采用预定义的帧结构的唤醒信号中增加第二指示信息，这样使得接入网设备只需将携带第二指示信息和转发指示信息的唤醒信号或者携带第二指示信息且采用预定义的帧结构的唤醒信号发送给第一终端设备即可，第一终端设备再基于唤醒信号中携带的转发指示信息或者唤醒信号是否采用预定义的帧结构确定是否基于第二指示信息唤醒第一终端设备的主链路，并在不基于第二指示信息唤醒第一终端设备的主链路时将第一指示信息转发给第二终端设备，由此第二终端设备无需定时切换到主链路收发数据，减小了第二终端设备的功耗，接入网设备也无需增加发射功率，因此不仅减小了接入网设备和第二终端设备的开销，也不容易干扰其他终端设备。
在一种可能的实施方式中，所述第一指示信息可以为所述第二终端设备的身份标识，所述第二指示信息可以为预设字段值；或者，
所述第一指示信息可以为所述第二终端设备的身份标识，所述第二指示信息可以为所述第一终端设备的身份标识；或者，
所述第一指示信息可以为所述预设字段值，所述第二指示信息可以为所述预设字段值；或者，
所述第一指示信息可以为所述预设字段值，所述第二指示信息可以为所述第一终端设备的身份标识。
这样使得唤醒信号可以采用多种帧结构，例如长比特与短比特，长比特与长比特，短比特与短比特以及短比特与长比特等，由此满足多种传输场景，减小了接入网设备和第二终端设备的开销。具体但不限于采用如下几种方式来实现携带第一指示信息和第二指示信息的唤醒信号的传输。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
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。
1)DRX机制，为了节省终端设备的功耗，3GPP协议所规定的NR***在release 15引入了DRX机制。DRX机制是为处于RRC连接态的终端设备配置一个DRX周期。DRX周期由“On Duration(唤醒期或唤醒时间或激活期或持续时间)”和“Opportunity for DRX(休眠期或休眠时间)”组成，在“On Duration”的时间内，终端设备监听并接收PDCCH，在“Opportunity for DRX”时间内，终端设备不接收PDCCH。当终端设备配置了一个DRX周期时，终端设备的状态可以分为DRX激活(active)态和DRX非激活(non-active)态(或者称为睡眠状态)，终端设备在激活时间(active time)内处于DRX active态，终端设备在非激活时间(non-active time)内处于DRX non-active态。当终端设备处于DRX激活时间时，终端设备会醒来监听并接收PDCCH，当终端设备处于DRX非激活时间时，终端设备会进入睡眠不监听并接收PDCCH以节省功耗。当以下任意一个定时器在运行时，终端设备即处于DRX激活时间：DRX持续时间定时器(drx-onDurationTimer)；DRX去激活定时器(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)。此外，DRX激活时间还包括其他情况，例如：终端设备在物理上行链路控制信道(physical uplink control channel，PUCCH)上发送了调度请求(scheduling request，SR)之后的等待期间；终端设备在成功接收到基于非竞争(non-contention based)随机接入的随机接入响应(random access response，RAR)之后还未收到指示新传的PDCCH期间。
2)WUS，如果接入网设备没有下行数据要发送，那么接入网设备可以通知终端设备睡眠一个长DRX周期，而不是定期醒来监测一段时间PDCCH后再进入睡眠。因此，NR***在release 16引入了WUS，配置了WUS的终端设备在开始长DRX周期之前醒来一段时间检查WUS，如果被告知无需唤醒，那么终端设备在下一个长DRX周期进入睡眠。接入网设备可以使用下行控制信息(downlink control information，DCI)格式2_6同时发送多个WUS，其中，一个比特表示一个终端设备的WUS。终端设备检查WUS所需的能量相较于检查其他DCI格式和PDCCH所需的能量较少，且监听WUS的持续时间远小于长DRX周期甚至DRX周期的持续时间，WUS有助于降低终端设备的功耗。
3)WUR，NR***在release 18引入了WUR，配置了WUR接口的终端设备通过WUR 链路或者主链路接收WUS，WUR链路的检查功耗低于主链路的睡眠功耗，WUR对终端设备的功耗节省增益显著。
4)主链路与WUR链路，主链路是接入网设备与终端设备之间不通过终端设备的WUR接口传输任一信号的链路，WUR链路是接入网设备与终端设备之间通过终端设备的WUR接口传输WUS的链路。
5)时频资源，对应于正交频分复用(orthogonal frequency division multiplexing,OFDM)符号和OFDM符号内的子载波。最小的时频资源是指一个OFDM符号内的一个子载波，被称为一个资源单元(resource element,RE)。物理层使用时频资源进行传输，传输是以12个子载波为一组进行调度，子载波组被称为物理资源块(physical resource block,PRB)。NR***中的时频资源代表了物理信道或者物理信号。在3GPP协议中，物理信道对应于承载高层信息的一组资源单元，而物理信号对应于不承载高层信息的一组资源单元。
6)定位测量技术，定位信息是根据下行定位参考信号(positioning reference signal，PRS)或上行信道探测参考信号(sounding reference signal，SRS)测量获得的。在下行测量中，基站及邻区基站配置PRS资源并在PRS资源上发送参考信号，终端设备在相应的资源位置上接收参考信号进行定位测量，获得信号接收功率、相对到达时间、收发时间差和到达角中的至少一个测量值，并将测量结果上报给对应的基站。类似的，在上行测量中，基站及邻区基站配置SRS资源，终端设备在相应的SRS资源上发送参考信号，基站在相应的资源位置上接收信号获得信号接收功率、相对到达时间、收发时间差和到达角中的至少一个测量值。两种定位测量方式中，基站及邻区基站都会把测量结果上报给核心网。核心网根据多个基站上报的定位测量结果计算出终端设备具体的位置，基站通过向核心网发送请求可以获得终端设备的位置信息。
7)覆盖测量技术，NR***中的覆盖测量也是通过特定的参考信号来测量无线信道的质量。以信道状态信息(channel state information，CSI)测量为例，基站为终端设备配置CSI资源并在CSI资源上发送参考信号。终端设备根据基站配置的资源位置进行参考信号接收，获得信道状态信息-参考信号接收功率(channel state information based reference signal Received Power，CSI-RSRP)和信道状态信息-信号与干扰加噪声比(channel state information based signal to noise and interference ratio，CSI-SINR)等能够表征覆盖信息的测量值，再通过周期或者非周期的方式把测量结果上报给基站。基站收到终端发来的测量结果后，即可获取当前基站到终端的下行覆盖情况。
8)本申请实施例中的术语“***”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，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的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。
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大小、内容、顺序、时序、优先级或者重要程度等。例如，第一终端设备和第二终端设备，只是为了区分不同的终端设备，而并不是表示这两个信息的优先级或者重要程度等的不同。
前文介绍了本申请实施例所涉及到的一些名词概念，下面介绍本申请实施例涉及的技术特征。
为了节省终端设备的功耗，3GPP协议所规定的NR***在release15引入了DRX机制。在release 16引入了WUS，在release 18引入了WUR。配置了WUS的终端设备在开始长DRX周期之前醒来一段时间检查WUS，如果被告知无需唤醒，那么终端设备在下一个长DRX周期进入睡眠。配置了WUR接口的终端设备通过WUR链路或者主链路接收WUS，WUR链路的检查功耗低于主链路的睡眠功耗，WUR对终端设备的功耗节省增益显著。但是WUR需要采用OOK、FSK等支持低功耗接收的调制方式，才能具有上述特征，而采用OOK、FSK等支持低功耗接收的调制方式传输WUS时，WUR链路的覆盖能力会比主链路差，部分边缘终端设备的WUR链路会超出接入网设备发送的WUS覆盖范围，此时要么终端设备定时切换到主链路接收WUS，但会产生较大功耗，要么接入网设备增加发射功率，但不仅会产生较大开销，也容易干扰其他终端设备。可见，当终端设备的WUR链路超出接入网设备发送的WUS覆盖范围时，由于终端设备无法通过WUR链路接收WUS，将导致终端设备的功耗增加或者接入网设备的开销增加的问题。
鉴于此，提供本申请实施例的技术方案。在本申请实施例中，接入网设备可以在唤醒信号中增加第二终端设备的唤醒指示信息，接入网设备只需将唤醒信号发送给第一终端设备即可，第一终端设备再基于唤醒信号确定是否将第二终端设备的唤醒指示信息转发给第二终端设备。可见，通过本申请实施例提供的技术方案，第二终端设备的唤醒指示信息可以由第一终端设备转发给第二终端设备，无需接入网设备直接发送给第二终端设备，由此第二终端设备无需定时切换到主链路收发数据，减小了第二终端设备的功耗，接入网设备也无需增加发射功率，因此不仅减小了接入网设备和第二终端设备的开销，也不容易干扰其他终端设备。
应理解，本申请实施例的技术方案可以应用于各种通信***，例如***(4th generation，4G)通信***(如长期演进(long term evolution，LTE)***)、第五代(5th generation，5G)通信***(如NR***)、机器类通信(machine type communication，MTC)***、设备到设备(device to device，D2D)***、物联网(internet of things，IoT)***、车联网(vehicle-to-everything，V2X)***，窄带物联网(narrow band internet of things，NB-IoT)***以及未来通信发展中出现的新的通信***等，具体的不做限制。

以上介绍了本申请实施例的技术方案适用的通信***，接下来结合附图介绍本申请实 施例提供的一种唤醒信号传输方法，请参见图2，为该方法的流程图。在下文的介绍过程中，以该方法应用于图1a所示的网络架构为例。
为了便于介绍，在下文中，以该方法由接入网设备和终端设备执行为例。因为本实施例是以应用在图1a所示的网络架构为例，因此，下文中所述的接入网设备可以是图1a所示的网络架构中的接入网设备，下文中所述的第一终端设备可以是图1a所示的网络架构中的终端设备1，下文中所述的第二终端设备可以是图1a所示的网络架构中的终端设备2。
S21、接入网设备确定唤醒信号。唤醒信号中携带第一指示信息。
在一些实施例中，接入网设备可以先确定唤醒信号传输中的转发设备和目标设备，再确定唤醒信号。其中，唤醒信号中携带第一指示信息，第一指示信息指示唤醒目标设备的主链路。
接入网设备在确定唤醒信号传输中的转发设备和目标设备时，先向核心网设备请求获取主链路在该接入网设备接收或发送的任一信号覆盖范围内的任意两个终端设备(如第一终端设备和第二终端设备)的终端类型信息和测量信息。其中，终端类型信息指示该终端设备是否为功耗不敏感终端设备，功耗不敏感终端设备可以是电池电量充足、电源供电、充放电比例高或者有帮助其他设备意愿的终端设备，具体的不做限制。测量信息指示该终端设备的位置以及该终端设备的WUR链路和主链路的覆盖情况。
再基于第一终端设备和第二终端设备的终端类型信息和测量信息，从第一终端设备和第二终端设备中确定唤醒信号传输中的转发设备和目标设备，例如确定第一终端设备为唤醒信号传输中的转发设备，第二终端设备为唤醒信号传输中的目标设备。其中，当第一终端设备为唤醒信号传输中的转发设备时，第一终端设备为功耗不敏感终端设备，第一终端设备的WUR链路的覆盖测量结果不小于第一阈值，第一终端设备的主链路的覆盖测量结果不小于第二阈值，即第一终端设备的WUR链路未超出接入网设备发送的唤醒信号覆盖范围，且第一终端设备的主链路未超出接入网设备接收或发送的任一信号覆盖范围。当第二终端设备为唤醒信号传输中的目标设备时，第二终端设备的WUR链路的覆盖测量结果小于第一阈值，第二终端设备的主链路的覆盖测量结果不小于第二阈值，第二终端设备与第一终端设备的距离不大于第三阈值，即第二终端设备的WUR链路超出接入网设备发送的唤醒信号覆盖范围，第二终端设备的主链路未超出接入网设备接收或发送的任一信号覆盖范围。
需要说明的是，在本申请实施例中，第一终端设备和第二终端设备可以在开机入网时通过随机接入消息中的Msg1或Msg3或MsgA向接入网设备发送终端类型信息。接入网设备在接收第一终端设备和第二终端设备的终端类型信息后，由于并不会立即使用第一终端设备和第二终端设备的终端类型信息，为了减少接入网设备的功耗，接入网设备可以先将第一终端设备和第二终端设备的终端类型信息转发给核心网设备，在确定唤醒信号传输中的转发设备和目标设备时，再向核心网设备请求获取第一终端设备和第二终端设备的终端类型信息。或者，接入网设备也可以不将第一终端设备和第二终端设备的终端类型信息转发给核心网设备，在确定唤醒信号传输中的转发设备和目标设备时，直接获取存储在本地的第一终端设备和第二终端设备的终端类型信息，具体的不做限制。
此外，如果终端设备不是功耗不敏感终端设备，可以向接入网设备发送终端类型信息，也可以不向接入网设备发送终端类型信息，即第二终端设备可以在开机入网时不通过随机接入消息中的Msg1或Msg3或MsgA向接入网设备发送终端类型信息，具体的不做限制。
需要说明的是，在本申请实施例中，第一终端设备和第二终端设备可以进行定位测量。定位信息是根据下行PRS或上行SRS测量获得的。在下行测量中，接入网设备例如基站及邻区基站配置PRS资源并在PRS资源上发送参考信号，第一终端设备和第二终端设备在相应的资源位置上接收参考信号进行定位测量，获得信号接收功率、相对到达时间、收发时间差和到达角中的至少一个测量值，并将测量结果上报给基站。在上行测量中，基站及邻区基站配置SRS资源，第一终端设备和第二终端设备在相应的SRS资源上发送参考信号，基站在相应的资源位置上接收信号获得信号接收功率、相对到达时间、收发时间差和到达角中的至少一个测量值。两种定位测量方式中，基站及邻区基站都会把测量结果上报给核心网设备。核心网设备根据多个基站上报的定位测量结果计算出第一终端设备和第二终端设备的位置，基站在确定唤醒信号传输中的转发设备和目标设备时，向核心网设备请求获取第一终端设备和第二终端设备的位置。
需要说明的是，在本申请实施例中，第一终端设备和第二终端设备可以进行覆盖测量。
针对WUR链路的覆盖测量，接入网设备例如基站给第一终端设备和第二终端设备配置一份时频资源，在该时频资源上发送WUR接口可以接收的采用包络调制的序列，第一终端设备和第二终端设备通过包络检波接收序列进行覆盖测量，获得信号接收功率、信号与干扰和噪声比值中的至少一个测量值，并将测量结果上报给基站。基站所发送的序列可以是NR***现在采用的m序列、gold序列或者其他新定义的序列，具体的不做限制。
针对主链路的覆盖测量，根据CSI-RS或同步信号和广播信道块(synchronization signal and pbch block，SSB)测量可以获得，当测量信号是CSI-RS时，基站配置CSI资源，第一终端设备和第二终端设备在相应的资源位置接收参考信号，获得信号接收功率、信号与干扰和噪声比值中的至少一个测量值，并将测量结果上报给基站。基站把主链路和WUR链路覆盖测量结果上报给核心网设备，核心网设备根据基站上报的主链路和WUR链路覆盖测量结果计算出第一终端设备和第二终端设备的WUR链路和主链路的覆盖情况，基站在确定唤醒信号传输中的转发设备和目标设备时，向核心网设备请求获取第一终端设备和第二终端设备的WUR链路和主链路的覆盖情况。
上述接入网设备确定了第一终端设备为唤醒信号传输中的转发设备，第二终端设备为唤醒信号传输中的目标设备，但是由于第二终端设备的WUR链路超出接入网设备发送的唤醒信号覆盖范围，第二终端设备无法通过WUR链路接收接入网设备发送的唤醒信号，如果第二终端设备定时切换到主链路收发数据，会产生较大功耗，如果接入网设备增加发射功率，不仅会产生较大开销，也容易干扰其他终端设备。因此接入网设备在确定唤醒信号时，唤醒信号中除了第一指示信息还可以携带转发指示信息或者唤醒信号采用预定义的帧结构。其中，转发指示信息指示转发设备(即第一终端设备)是否将第一指示信息转发给目标设备(即第二终端设备)，预定义的帧结构指示第一终端设备将第一指示信息转发给第二终端设备。通过在唤醒信号中增加转发指示信息或者唤醒信号采用预定义的帧结构，使得接入网设备只需将唤醒信号发送给第一终端设备即可，第一终端设备再基于唤醒信号中携带的转发指示信息或者唤醒信号是否采用预定义的帧结构确定是否将第一指示信息转发给第二终端设备，由此第二终端设备无需定时切换到主链路收发数据，减小了第二终端设备的功耗，接入网设备也无需增加发射功率，因此不仅减小了接入网设备和第二终端设备的开销，也不容易干扰其他终端设备。
此外，唤醒信号中还可以携带第二指示信息。其中，第二指示信息指示唤醒转发设备 的主链路。当唤醒信号中携带转发指示信息、第一指示信息和第二指示信息时，转发指示信息可以指示第一终端设备基于第二指示信息唤醒第一终端设备的主链路，但不将第一指示信息转发给第二终端设备，或者，转发指示信息还可以指示第一终端设备不基于第二指示信息唤醒第一终端设备的主链路，并将第一指示信息转发给第二终端设备。
需要说明的是，在本申请实施例中，转发指示信息可以为预设字段值，即唤醒信号显式指示第一终端设备是否将第一指示信息转发给第二终端设备。例如转发指示信息可以为1bit的1或0，当转发指示信息为0时，指示第一终端设备基于第二指示信息唤醒第一终端设备的主链路，发起随机接入或者等待寻呼，且不将第一指示信息转发给第二终端设备，当转发指示信息为1时，指示第一终端设备不基于第二指示信息唤醒第一终端设备的主链路，不发起随机接入或者等待寻呼，且将第一指示信息转发给第二终端设备；
转发指示信息也可以为加扰码字，即唤醒信号隐式指示第一终端设备是否将第一指示信息转发给第二终端设备。例如转发指示信息为码字1或码字2，码字1和码字2为正交码字。当转发指示信息为码字1时，指示第一终端设备基于第二指示信息唤醒第一终端设备的主链路，发起随机接入或者等待寻呼，且不将第一指示信息转发给第二终端设备，当转发指示信息为码字2时，指示第一终端设备不基于第二指示信息唤醒第一终端设备的主链路，不发起随机接入或者等待寻呼，且将第一指示信息转发给第二终端设备。
需要说明的是，在本申请实施例中，预定义的帧结构可以是唤醒信号中同时包含两个指示信息，分别为指示唤醒第一终端设备的主链路的第二指示信息，以及，指示唤醒第二终端设备的主链路的第一指示信息，也可以是其它帧结构，具体的不做限制。
需要说明的是，在本申请实施例中，第一指示信息可以为第二终端设备的身份标识(identity document，ID)，第二指示信息可以为预设字段值，例如，第一指示信息为ID2，第二指示信息为1bit的1，即唤醒信号采用长比特与短比特的帧结构；
或者，第一指示信息可以为第二终端设备的身份标识，第二指示信息可以为第一终端设备的身份标识，例如，第一指示信息为ID2，第二指示信息为ID1，即唤醒信号采用长比特与长比特的帧结构；
或者，第一指示信息可以为预设字段值，第二指示信息可以为预设字段值，例如，第一指示信息为1bit的1，第二指示信息为1bit的1，即唤醒信号采用短比特与短比特的帧结构；
或者，第一指示信息可以为预设字段值，第二指示信息为可以第一终端设备的身份标识，例如，第一指示信息为1bit的1，第二指示信息为ID1，即唤醒信号采用短比特与长比特的帧结构。
这样使得唤醒信号可以采用多种帧结构，例如长比特与短比特，长比特与长比特，短比特与短比特以及短比特与长比特等，由此满足多种传输场景，减小了接入网设备和第二终端设备的开销。
S22、接入网设备将唤醒信号发送给第一终端设备，第一终端设备接收接入网设备发送的唤醒信号，基于唤醒信号确定是否将第一指示信息转发给第二终端设备。
在一些实施例中，接入网设备可以通过主链路或WUR链路将唤醒信号发送给第一终端设备，相应的，第一终端设备通过主链路或WUR链路接收接入网设备发送的唤醒信号，并基于唤醒信号中携带的转发指示信息或者唤醒信号是否采用预定义的帧结构确定是否将第一指示信息转发给第二终端设备。
例如，当唤醒信号中携带的转发指示信息为1时，由于转发指示信息为1即指示第一终端设备不基于第二指示信息唤醒第一终端设备的主链路，不发起随机接入或者等待寻呼，且将第一指示信息转发给第二终端设备，此时第一终端设备可以基于该唤醒信号确定将第一指示信息转发给第二终端设备；
或者，当唤醒信号中携带的转发指示信息为码字2时，由于转发指示信息为码字2即指示第一终端设备不基于第二指示信息唤醒第一终端设备的主链路，不发起随机接入或者等待寻呼，且将第一指示信息转发给第二终端设备，此时第一终端设备可以基于该唤醒信号确定将第一指示信息转发给第二终端设备；
或者，唤醒信号采用预定义的帧结构，此时第一终端设备可以基于该唤醒信号确定将第一指示信息转发给第二终端设备。
S23、当第一终端设备基于唤醒信号确定将第一指示信息转发给第二终端设备时，第一终端设备将第一指示信息转发给第二终端设备，第二终端设备接收第一终端设备转发的第一指示信息，基于第一指示信息唤醒第二终端设备的主链路。
在一些实施例中，当第一终端设备基于唤醒信号中携带的转发指示信息或者唤醒信号采用预定义的帧结构确定将第一指示信息转发给第二终端设备时，第一终端设备可以通过反射和中继这两种方式将第一指示信息转发给第二终端设备，相应的，第二终端设备接收第一终端设备发送的第一指示信息，并基于第一指示信息唤醒第二终端设备的主链路，发起随机接入或者等待寻呼。
例如，第一终端设备可以包含反射模块，当基于转发指示信息确定将第一指示信息转发给第二终端设备时，第一终端设备打开反射模块将第一指示信息以反射的方式转发给第二终端设备，可选的，为了提高反射的强度，反射模块中可以含有功率放大器。
或者，第一终端设备可以不包含反射模块，当基于转发指示信息确定将第一指示信息转发给第二终端设备时，第一终端设备可以通过主链路或WUR链路将第一指示信息以中继的方式转发给第二终端设备，当第一终端设备通过主链路转发第一指示信息时，第一终端设备需要先唤醒主链路，完成第一指示信息的转发后再关闭主链路打开WUR链路。
以下结合具体的实例分别对这两种方式的具体实现进行详细的描述：
方式一，若第一指示信息为第二终端设备的身份标识：ID2，第一终端设备可以通过反射方式或者中继方式将第一指示信息转发给第二终端设备。
例如，若第二指示信息为预设字段值：1bit的1，即唤醒信号采用长比特与短比特的帧结构，则接入网设备先通过RRC配置第一DCI，通过主链路将第一DCI发送给第一终端设备，其中，第一DCI指示第一终端设备的监听位置，再通过主链路或WUR链路将唤醒信号发送给第一终端设备。请参见图3，为第一种唤醒信号的示意图，该唤醒信号中携带预设字段值：1bit的1、转发指示信息：1bit的1或0以及第二终端设备的身份标识：ID2。第一终端设备在第一终端设备的监听位置上接收到1bit的1时读取唤醒信号中的其他字段，基于唤醒信号中携带的转发指示信息或者唤醒信号是否采用预定义的帧结构确定是否通过反射方式或者中继方式将ID2转发给第二终端设备，如果转发指示信息为1bit的1或者唤醒信号采用预定义的帧结构，则通过反射方式或者中继方式将ID2转发给第二终端设备；
若第二指示信息为第一终端设备的身份标识：ID1，即唤醒信号采用长比特与长比特的帧结构，则接入网设备通过主链路或WUR链路将唤醒信号发送给第一终端设备。请参见图4，为第二种唤醒信号的示意图，该唤醒信号中携带第一终端设备的身份标识：ID1、 转发指示信息：1bit的1或0以及第二终端设备的身份标识：ID2。第一终端设备在接收到ID1时读取唤醒信号中的其他字段，基于唤醒信号中携带的转发指示信息或者唤醒信号是否采用预定义的帧结构确定是否通过反射方式或者中继方式将ID2转发给第二终端设备，如果转发指示信息为1bit的1或者唤醒信号采用预定义的帧结构，则通过反射方式或者中继方式将ID2转发给第二终端设备。
方式二，若第一指示信息为预设字段值：1bit的1，第一终端设备只能通过中继方式将第一指示信息转发给第二终端设备。
例如，若第二指示信息为预设字段值：1bit的1，即唤醒信号采用短比特与短比特的帧结构，则接入网设备先通过RRC配置第二DCI和第三DCI，通过主链路将第二DCI发送给第一终端设备，通过主链路将第三DCI发送给第二终端设备，其中，第二DCI指示第一终端设备的监听位置，第三DCI指示第二终端设备的监听位置，再通过主链路或WUR链路将唤醒信号发送给第一终端设备。请参见图5，为第三种唤醒信号的示意图，该唤醒信号中携带预设字段值：1bit的1、转发指示信息：1bit的1或0以及第二终端设备的监听位置。第一终端设备在第一终端设备的监听位置上接收到1bit的1时读取唤醒信号中的其他字段，基于唤醒信号中携带的转发指示信息或者唤醒信号是否采用预定义的帧结构确定是否通过中继方式在第二终端设备的监听位置上发送1bit的1，如果转发指示信息为1bit的1或者唤醒信号采用预定义的帧结构，则通过中继方式在第二终端设备的监听位置上发送1bit的1；
若第二指示信息为第一终端设备的身份标识：ID1，即唤醒信号采用短比特与长比特的帧结构，则接入网设备先通过主链路将第三DCI发送给第二终端设备，再通过主链路或WUR链路将唤醒信号发送给第一终端设备。请参见图6，为第四种唤醒信号的示意图，该唤醒信号中携带第一终端设备的身份标识：ID1、转发指示信息：1bit的1或0以及第二终端设备的监听位置。第一终端设备在接收到ID1时读取唤醒信号中的其他字段，基于唤醒信号中携带的转发指示信息或者唤醒信号是否采用确定是否通过中继方式在第二终端设备的监听位置上发送1bit的1或者唤醒信号采用预定义的帧结构，如果转发指示信息为1bit的1，则通过中继方式在第二终端设备的监听位置上发送1bit的1。
上述实施例中，当第一终端设备的WUR链路未超出接入网设备发送的WUS覆盖范围，第二终端设备的WUR链路超出接入网设备发送的WUS覆盖范围时，接入网设备可以在唤醒信号中增加转发指示信息和第二终端设备的唤醒指示信息或者确定唤醒信号采用预定义的帧结构且在唤醒信号中增加第二终端设备的唤醒指示信息，接入网设备只需将唤醒信号发送给第一终端设备即可，第一终端设备再基于唤醒信号中携带的转发指示信息或者唤醒信号是否采用预定义的帧结构，确定是否将第二终端设备的唤醒指示信息转发给第二终端设备。可见，通过本申请实施例提供的技术方案，第二终端设备的唤醒指示信息可以由第一终端设备转发给第二终端设备，无需接入网设备直接发送给第二终端设备，由此第二终端设备无需定时切换到主链路收发数据，减小了第二终端设备的功耗，接入网设备也无需增加发射功率，因此不仅减小了接入网设备和第二终端设备的开销，也不容易干扰其他终端设备。
