背景技术
在以物联网(Internet of Things，IoT)为代表的通信场景中，站点通常是使用电池供电的，其对低能耗有非常高的要求。通过睡眠机制可以使得能耗大大降低，睡眠周期越长，节能效果越好。但是过长的睡眠周期，会导致传输时延的增加。
为了解决上述问题，通常在站点中增加一个唤醒收发机(Wakeup Radio，WUR)。WUR有常打开和周期性打开两种运行模式，常打开运行模式下WUR永远处于打开状态，或者当主链路关闭的情况下WUR永远处于打开状态，常打开运行模式运行机制简单，不需要AP对WUR的打开时间进行管理和调度，但是省电效果相比周期性打开运行模式要高很多。对于周期性打开运行模式，通过目标唤醒时间(Target Wake Time，TWT)预约WUR的打开周期，使得WUR在TWT到达之后打开并保持一定的唤醒时长。如果在该唤醒时长内收到唤醒帧，则唤醒主链路进行数据接收，如果在该唤醒时长内没有收到唤醒帧，则该时长结束后将WUR关闭，等待下一个TWT时间到达后再次打开WUR。
因此，在站点中增加WUR的基础上，可以提供一种唤醒方法，进一步降低站点的能耗。
发明内容
本申请提供一种唤醒方法和设备，能够降低站点的能耗。
第一方面，提供了一种唤醒方法，该方法由站点中的唤醒收发机(Wake-up Radio，WUR)执行，该方法包括：该唤醒收发机接收第一唤醒帧，该第一唤醒帧包括时长字段，该时长字段用于承载时长信息；该唤醒收发机根据该时长信息，唤醒主收发机。
根据本申请的唤醒方法，唤醒收发机接收到的唤醒帧中包括时长信息，唤醒收发机根据时长信息唤醒主收发机，由此能够使站点更好的节能。
结合第一方面，在第一方面的一种可能的实现方式中，该时长信息用于指示该唤醒收发机接收完该第一唤醒帧的时刻与该唤醒收发机开始唤醒主收发机的时刻之间的第一时间间隔；
其中，该唤醒收发机根据该时长信息，唤醒主收发机，包括：该唤醒收发机从接收完该第一唤醒帧的时刻开始经过该第一时间间隔后，开始唤醒该主收发机。
可以理解的是，唤醒收发机接收到第一唤醒帧后，可以在经过小于该第一时间间隔的时间间隔后唤醒主收发机。
结合第一方面，在第一方面的一种可能的实现方式中，该时长信息用于指示该唤醒收发机接收完该第一唤醒帧的时刻与主收发机被唤醒的时刻之间的第二时间间隔；

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清楚、完整地描述。
本申请实施例的唤醒方法可以应用于无线局域网(Wireless Local Area Network，WLAN)中，也可以应用于其它各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，GSM)系统、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)系统、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统，以及未来的通信系统等。
图1是本申请实施例的应用场景的示意图。图1所示的WLAN中包括发送端设备(例如图1中所示的接入点(Access Point，AP)和接收端设备(例如图1中所示的站点(Station，STA)。AP负责与多个STA进行双向通信，例如图1中示出的AP向STA(例如图1中的STA1和STA2)发送下行数据，或者AP接收来自STA(例如图1中的STA3)的上行数据。应理解，图1中示出的AP和STA的个数仅是示意性的，WLAN中可以包括 任意数量的AP和STA。
图2是现有的低能耗方案中发送端设备和接收端设备交互的示意图。接收端设备包括主收发机2和唤醒收发机(Wake-up Radio，WUR)，发送端设备包括主收发机1。当接收端设备的主收发机2进入休眠后，低功耗的WUR苏醒开始工作。如果发送端设备需要与接收端设备通信，发送端设备首先通过WUR信道向接收端设备的WUR发送唤醒帧。WUR正确收到发送给自己的唤醒帧后，唤醒接收端设备的主收发机2。发送端设备则通过主收发机1与苏醒的主收发机2进行通信。当主收发机2与发送端设备完成通信后，WUR侦听是否有发送给自己的唤醒帧，以便在收到唤醒帧时唤醒主收发机2。
上述技术采用低功耗的WUR代替主收发机2在接收端设备空闲时侦听信道，能够有效降低接收端设备在Idle listening中的能量浪费。WUR为了实现低功耗，其电路构造、帧(例如唤醒帧)结构设计等方面，一般具有低的复杂度。WUR侦听状态的能耗约为主收发机2的0.1～1％，即小于100uW。
应理解，某接收端设备的主收发机只能被对应该接收端设备的WUR唤醒。主收发机通常也可以叫做主收发模块或主射频模块、主射频器。本文中未作特殊说明的情况下，主收发机和WUR均指同一接收端设备的主收发机和WUR。发送端设备可以包括WUR也可以不包括WUR，当发送端设备不包括WUR时，其主收发机也可以认为是传统的收发器。
应理解，唤醒收发机的目的是使主收发机处于开(ON)，即苏醒的状态。因此，“唤醒主接收机”包含以下情况：主接收机原来处于关(OFF)，即休眠的状态，“唤醒主接收机”指将主接收机转换成ON的状态；主接收机原来处于ON的状态，“唤醒主接收机”指维持主接收机为ON的状态。
还应理解，WUR关闭也可以描述为“WUR进入睡眠状态或功率节省状态”，WUR打开也可以描述为“WUR进入清醒状态或工作状态”。
随着无线设备的功能的日趋多样化，物联网(Internet of Things，IoT)已经成为未来无线网络的发展趋势。如何降低IoT中的站点的能耗是目前非常重要的一个问题。
为了解决上述问题，本申请实施例提供了一种唤醒方法。图3示出了本申请实施例的唤醒方法100的示意性流程图。该方法100包括：
S110，接入点生成第一唤醒帧，第一唤醒帧中包括时长字段，时长字段用于承载时长信息；
S120，接入点向站点发送第一唤醒帧，站点中的唤醒收发机接收接入点发送的该第一唤醒帧；
S130，唤醒收发机根据时长信息，唤醒主收发机。
可选地，作为一个实施例，时长信息用于指示唤醒收发机接收完第一唤醒帧的时刻与唤醒收发机开始唤醒主收发机的时刻之间的第一时间时间间隔。相对应的，唤醒收发机从接收完第一唤醒帧的时刻开始经过第一时间间隔后，开始唤醒主收发机。
可以理解的是，唤醒收发机可以从接收完第一唤醒帧的时刻开始经过小于第一时间间隔的时间间隔后，开始唤醒主收发机。
举例来说，时长信息指示的第一时间间隔为T1，本申请对T1的取值不作限定。当T1的取值为0时，表示唤醒收发机接收完第一唤醒帧后，立即唤醒主收发机。当T1的取值不为0时，表示唤醒收发机接收完第一唤醒帧后，等待T1时间开始唤醒主收发机。
可选地，作为另一个例子，时长信息用于指示唤醒收发机接收完第一唤醒帧的时刻与唤醒收发机被唤醒的时刻之间的第二时间间隔。相对应的，唤醒收发机根据第二时间间隔确定开始唤醒主收发机的时刻，并在确定的时刻开始唤醒主收发机。由此，当有下行数据的站点比较多，但接入点无法同时服务这么多站点的情况下，可以将一部分站点延迟一段时间再唤醒，使得这部分站点在这段时间内无需唤醒主收发机，进而节省能量。
举例来说，时长信息指示的第二时间间隔为T2，本申请对T2的取值不作限定。唤醒收发机从开始唤醒主收发机到主收发机被唤醒之间的时间间隔为T3，则唤醒收发机需要从接收完第一唤醒帧的时刻开始经过T2-T3后开始唤醒主收发机。
在上述实施例中，可选地，站点属于多个站点组中的目标站点组，接入点发送给站点的第一唤醒帧中还包括组标识字段，组标识字段用于承载组标识。站点在接收到第一唤醒帧后，判断第一唤醒帧是否是发送给自己的唤醒帧，如果确定第一唤醒帧是发送给自己的唤醒帧，站点解析第一唤醒帧，并根据第一唤醒帧中的时长信息，唤醒主收发机。需要说明的是，目标站点组是多个站点组中的任意一个站点组。
在本申请实施例中，接入点可以根据预设条件将站点进行分组，得到多个站点组。例如，接入点根据每个站点的业务类型将站点进行分组得到多个站点组。具体地，接入点将业务类型相同的站点分为一组。
例如，接入点可以根据每个站点对时延的需求的不同进行分组，将时延需求类似的站点分为一组，得到多个站点组，由此便于每个站点组中的站点获得相同的时延效果。
再例如，接入点根据站点的关联标识(Association ID，AID)对站点进行分组，将AID在一定范围内的站点分为一组，或者可以理解为，每个站点组中的所有站点的AID的属于同一个AID集合，任意两个AID集合中的元素完全不同，每个站点组的组标识与AID集合具有对应关系。由此，站点可以根据组标识字段中承载的组标识和该对应关系，确定第一唤醒帧是否是发送给自己的唤醒帧。
其中，每个站点组中所有站点的AID可以是连续的，或者说每个站点组包含一段连续AID对应的站点。每个站点组中所有站点的AID还可以是不连续的，本申请对此不作限定。
举例来说，站点组1的组标识为组标识1，站点组2的组标识为组标识2，站点组3的组标识为组标识3，组标识1对应AID集合1，站点组2对应AID集合2，组标识3对应AID结合3，AID集合1中的元素的值介于100和150之间，AID集合2中的元素的值介于150和200之间，AID集合3中的元素的值介于200和250之间，如果站点的AID为160，则站点属于站点组2，如果第一唤醒帧中的组标识字段承载的组标识为组标识2，则站点认为第一唤醒帧是发送给自己的唤醒帧，需要进行解析，否则，站点认为第一唤醒帧不是发送给自己的唤醒帧，无需进行解析，由此进一步节省能量。
作为一个实施例，组标识与AID集合的对应关系可以是预先设置的。组标识与AID集合的对应关系还可以是接入点根据站点的AID进行分组后，通过广播的方式将组标识与AID集合的对应关系告知所有站点。
进一步地，AID集合的划分方式可以是预先设置的。AID集合的划分方式可以是接入点通过广播的方式告知所有站点的。接入点可以将每个AID集合中包括的AID的值告知站点，或者，接入点可以将每个AID集合中的AID的最小值和最大值告知站点，并且指示每个AID集合中的AID的值是连续的。或者，接入点可以只将每个AID集合中的 AID的最小值和每个AID集合中的元素的个数告知站点，并且指示每个AID集合中的AID的值是连续的。
在上述所有实施例中，每个站点组具有各自的唤醒周期，每个站点组中的站点按照本组的唤醒周期打开WUR接收唤醒帧。其中，每个唤醒组的唤醒周期可以是接入点根据每个站点组中的站点的业务周期确定的。
在本申请实施例中，可选地，第一唤醒帧中还包括业务指示地图(Traffic Indication Map，TIM)字段，如图4所示出的，该TIM字段中包括比特位图(Bitmap)字段，Bitmap中的每一个比特对应一个站点(或WUR)。当某比特设置“0”代表对应的站点没有要接收的数据，该站点的WUR可以进入睡眠状态；反之，当某比特设置为“1”代表对应的站点有要接收的数据。
在上述所有实施例中，可选地，为了对一个组中的不同站点采用不同的唤醒帧，接入点在一个唤醒周期内发送多个唤醒帧。第一唤醒帧中包括唤醒帧数目指示字段，该唤醒帧数据指示字段用于承载唤醒帧数目指示信息，唤醒帧数目指示信息指示唤醒收发机是否需要在第一唤醒帧的接收周期内接收第二唤醒帧。
可以理解的是，第二唤醒帧是对在第一唤醒帧之后发送的唤醒帧的一个统称，并不一定指的是一个唤醒帧。并且，第二唤醒帧中同样可以包括唤醒帧数目指示字段。
例如，如图5中所示出的，唤醒帧数目指示字段可以为1个比特，设置为“0”表示本发送周期内接入点没有更多的唤醒帧需要发送，设置为“1”表示本发送周期内接入点还有需要发送的唤醒帧。
或者，进一步的，当第一唤醒帧中携带组标识字段时，唤醒帧数目指示字段可以用于指示本发送周期内接入点是否有更多个携带相同组标识的唤醒帧需要发送。
更进一步地，唤醒帧数目指示字段可以为多个比特，用于指示本发送周期内接入点还有多少个唤醒帧需要发送。
需要说明的是，当第一唤醒帧中的唤醒帧数目指示信息指示接入点在本申请周期内还有需要发送的唤醒帧时，接入点在第一唤醒帧之后向目标站点组中的所有站点发送的唤醒帧可以只针对该目标站点组中的部分站点。或者可以理解为，接入点可以根据站点的AID将目标站点组分为多个更小的站点组，接入点在第一唤醒帧之后向目标站点组中的所有站点发送的唤醒帧中携带的组标识仅与这些更小的站点组中的某些站点组对应，由此仅这某些更小的站点组中的站点需要对在第一唤醒帧之后接收到的这个唤醒帧进行解析，其他更小的站点组中的站点不需要解析在第一唤醒帧之后接收到的这个唤醒帧，由此能够节能。
需要理解的是，在本申请实施例中，接入点根据站点的AID对站点进行分组的相关实施例，可以是在基于方法100的基础上被执行的，也可以是单独被执行的。当接入点根据站点的AID对站点进行分组的相关实施例被单独执行时，本申请另一实施例提供了一种唤醒方法，如图6所示，方法200包括：
S210，接入点根据站点的关联标识AID将多个站点进行划分得到多个站点组；
其中，每个站点组中的所有站点的AID属于同一个AID集合，任意两个AID集合中的元素完全不同，每个站点组的组标识与AID集合具有对应关系。
S220，接入点向目标站点组中的站点发送第一唤醒帧，站点接收第一唤醒帧；
S230，当站点根据目标站点组的组标识和对应关系，确定需要解析第一唤醒帧时， 解析第一唤醒帧。
可以理解的是，接入点向目标站点组发送的第一唤醒帧可以被称为“组唤醒帧”。
可选地，作为一个例子，第一唤醒帧中包括TIM字段，并且TIM字段中承载的信息与方法100中相同，为避免重复，在此不再赘述。
可选地，作为另一个例子，第一唤醒帧还包括唤醒帧数目指示字段，并且唤醒帧数目指示字段中承载的信息与方法100中相同，为避免重复，在此不再赘述。
作为一个实施例，当接入点需要对站点组中的站点发送组播或者单播唤醒帧，但接入点无法同时服务多组站点时，接入点可以控制一部分站点的唤醒收发机完成唤醒帧的接收之后关闭一段时间再进入工作状态，由此实现站点的节能。
具体地说，接入点向站点发送的第一唤醒帧中携带时间字段，时间字段用于承载时间信息，该时间信息用于指示唤醒收发机在确定站点没有要接收的数据时，唤醒收发机在接收完第一唤醒帧的时刻由工作状态进入睡眠状态，从进入睡眠状态的时刻开始经过预设时间间隔后进入工作状态。
作为另一个实施例，当接入点确定目标站点组中的所有站点在一个唤醒周期内均没有需要接收的下行数据的情况下，该第一唤醒帧可以为一个特殊的唤醒帧，该第一唤醒帧用于通知目标站点组中的所有站点将唤醒收发机关闭，直到下一个唤醒周期时再将唤醒收发机打开。
例如，通过第一唤醒帧中的TIM字段指示目标站点组中的所有站点均没有需要接收的下行数据。例如，把TIM字段中的所有比特都设置为“0”，或者将TIM字段的Bitmap长度设置为“0”。
在本申请实施例中，为了支持唤醒机制，接入点需要通过主链路与站点进行唤醒能力的协商以及对唤醒收发机操作的参数进行设置。因此本申请实施例提供了另一种唤醒方法，如图7所示，方法300包括：
S310，站点生成第一消息，该第一消息中包括唤醒延迟信息，该唤醒延迟信息用于指示站点中的唤醒收发机从成功接收完接入点发送的唤醒帧到唤醒该站点中的主收发机之间的时间间隔；
S320，站点通过主收发机向接入点发送第一消息，接入点接收站点通过主收发机发送的第一消息，
S330，接入点根据第一消息，发送数据。
具体来说，接入点接收到该第一消息之后，根据第一消息可以获知站点的唤醒收发机从开始唤醒主收发机到主收发机被唤醒之间的时间间隔，由此，当接入点向站点发送唤醒帧之后，接入点会等待该时间间隔后再向站点发送数据。由于站点向接入点发送的第一消息中包括唤醒延迟信息，使得接入点能够根据唤醒延迟信息确定出更为准确的发送数据的时间。
可选地，作为一个实施例，第一消息中还包括下列信息中的至少一种：信道指示信息、唤醒收发机操作模式信息和第一唤醒帧支持信息。其中，信道指示信息指示唤醒收发机的信道信息，该信道信息包括唤醒收发机的信道的带宽和/或信道的位置。唤醒收发机的操作模式信息指示唤醒收发机的操作模式，例如，可以通过一个比特承载唤醒收发机的操作模式信息，比特的值设为“0”代表唤醒收发机的操作模式为常打开模式，比特的值设为“1”代表唤醒收发机的操作模式为周期性打开模式。第一唤醒帧支持信息用于 指示站点是否支持唤醒帧的接收，例如，可以通过一个比特承载第一唤醒帧支持信息，比特的值设为“0”代表站点不支持唤醒帧的接收，比特的值设为“1”代表站点支持唤醒帧的接收。
可选地，作为一个实施例，接入点接收站点发送的探测请求(Probe Request)帧，探测请求帧中携带第一消息。
进一步地，接入点可以向站点的主收发机发送第二消息，第二消息包括下列信息中的至少一种：信道操作信息、唤醒帧发送周期信息和第二唤醒帧支持信息。其中，信道操作信息用于指示接入点当前使用的信道的带宽和/或信道的位置和/或发送模式信息。唤醒帧发送周期信息用于指示唤醒帧的发送周期。第二唤醒帧支持信息用于指示接入点是否支持唤醒帧的发送，例如，可以通过一个比特承载第二唤醒帧支持信息，比特的值设为“0”代表接入点不支持唤醒帧的发送，比特的值设为“1”代表站点支持唤醒帧的发送。
可选地，作为一个实施例，接入点向站点的主收发机发送信标(Beacon)帧，该Beacon中携带第二消息。或者接入点向站点的主收发机发送探测响应(Probe Response)帧，该探测响应帧中携带第二消息。
