随着移动通信技术的发展，移动应用日趋多样化，设备功能不断丰富。降低设备的能耗成为无线网络的重要技术目标之一。其中，节点智能省电是实现低能耗的一种主要手段。节点在省电休眠后如何实现唤醒，例如，在出现紧急业务需求或出现实时业务需求时，如何唤醒节点是一项待解决的难题。无线局域网(Wireless Local Area Networks，WLAN)领域，在传统的802.11协议(例如，802.11b、802.11a、802.11g、802.11n、802.11ac等)中相关的解决方案主要集中在优化设备的休眠策略上。
在WLAN中，设备相当一部分能量浪费在无接收信号时的空闲侦听(Idle Listening)上，因此除了优化休眠策略以外，减少设备在Idle Listening中的能耗是另一条降低能耗的技术途径。当前的一种方案是使用低功耗唤醒收发机(Low Power Wake-Up Receiver，LP-WUR)实现，其中，LP-WUR可以简称为唤醒收发机(Wake-Up Receiver，WUR)。该方案的核心思想是站点(Station，STA)，除包括传统的主收发机(Main Radio)，例如802.11Main Radio、无线保真(Wireless Fidelity，Wi-Fi)Main Radio以外，新增一个WUR。
目前除了STA对能耗要求比较高以外，接入点(Access Point，AP)的节能也成为一个重要的研究领域。现有相关技术中，AP在希望进入节能模式时，可以作为目标唤醒时间(Target Wake Time，TWT)请求节点向其他的TWT应答节点发送TWT请求信息，请求设定一个醒来的时间。或者AP可以在信标(Beacon)帧中直接广播TWT信息单元，并在TWT信息单元所规定的清醒时间之前的时间内进行休眠。
但是，在AP进入休眠状态后，即使STA有上行数据包需要传输，也只能等到AP醒来之后才能发送，导致较高的传输时延。
发明内容
本申请提供一种唤醒方法、站点和接入点，能够降低信息传输的时延。
第一方面，提供了一种唤醒方法，该方法应用于通信系统中，该通信系统中包括接入点AP和至少一个站点STA，该AP包括唤醒收发机WUR和主收发机，该方法包括：第一STA确定该AP的当前状态为休眠状态，其中，当该AP处于休眠状态时，该AP中的主收发机处于关闭状态；该第一STA向该AP中的WUR发送唤醒帧，该唤醒帧用于触发该AP中的WUR唤醒该AP中的主收发机。
根据本申请的唤醒方法，站点在确定接入点处于休眠状态时，能够通过发送唤醒帧唤醒接入点，之后进行上行数据的传输，由此能够降低上行数据传输的时延。
结合第一方面，在第一方面的一种可能的实现方式中，该方法还包括：该第一STA向该AP中的主收发机发送第一能力信息帧，该第一能力信息帧携带第一指示信息，该第一指示信息用于指示该第一STA是否具有发送唤醒帧的能力。

也就是说，休眠通知帧可以是周期性发送的。AP可以在一个发送周期内发送多个休眠通知帧，STA根据休眠通知帧中携带的数量信息接收休眠通知帧，并根据接收到的休眠通知帧确定AP处于休眠状态的时间段。
AP发送多个休眠通知帧能够保证所有的STA都能够接收到休眠通知帧，提高系统的鲁棒性。

需要说明的是，AP发送的唤醒声明帧是广播发送给多个STA的。由此STA根据唤醒声明帧确定AP处于唤醒状态之后，可以直接向AP发送数据。而不需要通过发送唤醒帧的方式将AP先进行唤醒再进行数据的发送。能够节省信令和降低数据传输时延。
结合第一方面及其上述可能的实现方式，在第一方面的另一可能的实现方式中，该方法还包括：该第一STA确定至少一个第二STA的上行传输需求；其中，该第一STA向该AP中的WUR发送唤醒帧，包括：该第一STA向该AP中的WUR发送携带数据发送需求信息的唤醒帧，该数据发送需求信息用于指示该至少一个第二STA的上行传输需求。

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所示的无线局域网(Wireless Local Area Network，WLAN)中包括接入点(Access Point，AP)和站点(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是根据本申请实施例的接入点和站点进行交互的示意图。接入点包括主收发机1和WUR 1，站点包括主收发机2和WUR 2。当站点的主收发机2进入休眠后，低功耗的WUR 2苏醒开始工作。如果AP需要与站点通信，AP首先通过WUR信道向站点的WUR2发送唤醒包(Wake-up Packet)。WUR 2正确收到发送给自己的Wake-up Packet后，唤醒站点的主收发机2。接入点则通过主收发机1与苏醒的主收发机2进行通信。当主收发机2与接入点完成通信后，主收发机2进入休眠状态，WUR 2侦听是否有发送给自己的Wake-up Packet，以便在收到Wake-up Packet时唤醒主收发机2。
同样地，当接入点的主收发机1进入休眠后，低功耗的WUR 1苏醒开始工作。如果站点需要与接入点进行通信，站点首先通过WUR信道向接入点的WUR 1发送Wake-up Packet。WUR 1正确接收到发送给自己的Wake-up Packet后，唤醒接入点的主收发机1。站点通过主收发机2与苏醒的主收发机1进行通信。当主收发机1与站点完成通信后，主收发机1进入休眠状态，WUR 1侦听是否有发送给自己的Wake-up Packet，以便在收到Wake-up Packet时唤醒主收发机1。
上述技术采用低功耗的WUR代替主收发机在设备(站点或接入点)空闲时侦听信道，能够有效降低设备在Idle listening中的能量浪费。WUR为了实现低功耗，其电路构造、帧(例如wake-up packet)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，某设备的主收发机只能被对应该设备的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均指同一设备的主收发机和WUR。
应理解，WUR的目的是使主收发机处于开(ON)，即苏醒的状态。因此，“唤醒主收发机”包含以下情况：主收发机原来处于关(OFF)，即休眠的状态，“唤醒主收发机”指将主收发机转换成ON的状态；主收发机原来处于ON的状态，“唤醒主收发机”指维持主收发机为ON的状态。
还应理解，WUR关闭也可以描述为“WUR进入睡眠状态或休眠状态或功率节省状态”，WUR打开也可以描述为“WUR进入清醒状态或打开状态或工作状态”。
随着无线设备的功能的日趋多样化，尤其是移动AP的出现，以及STA作为热点共享WiFi的应用逐渐增加，在这样的应用场景中，AP无法获得交流电的无间断供应，只能依靠有限容量的电池，导致AP的电量也会出现消耗殆尽的情况。由此，可以使AP采用与STA类似的节能方法进行节能。因此，需要提供一种唤醒方法，降低AP由于进入睡眠状态导致的传输时延。
图3示出了根据本申请实施例的唤醒方法。该唤醒方法应用于图1所示的通信系统中，图1所示的通信系统中的接入点包括唤醒收发机WUR和主收发机，如图3所示，方法100包括：
S110，第一STA确定AP的当前状态为休眠状态，其中，当AP处于休眠状态时，AP中的主收发机处于关闭状态；
S120，第一STA向AP中的WUR发送唤醒帧，该唤醒帧用于触发AP中的WUR唤醒AP中的主收发机。
因此，本申请实施例的唤醒方法，站点能够通过向接入点发送唤醒帧的方式唤醒接入点进行数据的传输，不需要等到接入点的预设的休眠时间结束时才向接入点发送数据。由此，能够降低上行数据传输的时延。
可以理解的是，在AP进入休眠状态之前，AP与STA之间可以进行能力交互，使得STA知道AP是否能够被唤醒，以及使得AP知道STA是否具有唤醒能力。
举例来说，第一STA可以向AP中的主收发机发送第一能力信息帧，第一能力信息帧中携带第一指示信息，该第一指示信息用于指示第一STA是否具有发送唤醒帧的能力。AP可以向第一STA发送第二能力信息帧，第二能力信息帧中携带第二指示信息和/或第三能力指示信息，第二能力指示信息用于指示AP是否包括WUR，第三能力指示信息用于指示AP是否能够被第一STA唤醒。第一STA在根据第二指示信息和/或第三指示信息确定AP能够被唤醒的情况下，向AP发送唤醒帧。
进一步地，AP可以将唤醒标识(Wakeup ID)发送给STA，以便于STA根据Wakeup ID向AP发送唤醒帧，并且唤醒帧中携带Wakeup ID，该Wakeup ID可以为AP中的WUR的标识。可选地，AP将Wakeup ID携带在第二能力信息帧中发送给STA。
具体地，第一STA可以向AP发送探测请求帧(Probe Request Frame)，如图4所示，该Probe Request Frame中包括唤醒帧发送能力字段，唤醒帧发送能力字段用于指示第一STA是否具有发送唤醒帧的能力。相对应地，AP可以向第一STA发送的探测响应帧中(Probe Response Frame)，Probe Response Frame中包括WUR配置字段、WUR操作字段和Wakeup ID字段中的至少一个字段。例如，图4中示出的Probe Response Frame中包括上述三个字段，其中，WUR配置字段用于指示AP是否包括WUR，WUR操作字段用于指示AP是否能够被唤醒，Wakeup ID字段用于指示Wakeup ID。
或者，第一STA可以向AP发送关联请求帧(Association Request Frame)，如图5中所示出的，该Association Request Frame中包括唤醒包发送能力字段，唤醒包发送能力字段用于指示第一STA是否具有发送唤醒包的能力。相对应地，AP可以向第一STA发送的关联响应帧中(Association Response Frame)，Association Response Frame中包括WUR配置字段、WUR操作字段和Wakeup ID字段中的至少一个字段。例如，图5中示出的Association Response Frame中包括上述三个字段，其中，WUR配置字段用于指示AP是否包括WUR，WUR操作字段用于指示AP是否能够被唤醒，Wakeup ID字段用于指示Wakeup ID。
或者，AP可以先向第一STA发送信标帧(Beacon Frame)，该Beacon Frame中包括WUR配置字段、WUR操作字段和Wakeup ID字段中的至少一个字段。例如，图6中示出的Beacon Frame中包括上述三个字段，其中，WUR配置字段用于指示AP是否包括WUR，WUR操作字段用于指示AP是否能够被唤醒，Wakeup ID字段用于指示Wakeup ID。
由此，通过AP与STA之间进行唤醒能力的交互，为采用本申请实施例的唤醒方法提供能力保障。
在本申请实施例中，可选地，在AP进入休眠状态之前，AP通知所有STA自己将进入休眠状态，以便于STA获知AP的状态。AP通过主收发机向STA发送休眠通知帧， 休眠通知帧中携带休眠状态指示信息，该休眠状态指示信息用于指示与休眠状态相关的信息。
具体来说，休眠通知帧中包括第四指示信息，第四指示信息指示AP发送完休眠通知帧后将进入休眠状态，在休眠期间AP中的WUR会打开，STA可以通过发送唤醒帧唤醒AP。第四指示信息可以通过帧类型来体现，即使用一个特定的帧类型标识AP将进入休眠状态，第四指示信息还可以通过一个特定的信息域来体现。例如，该特定的信息域的值为1表示AP将进入休眠状态，值为0表示AP不进入休眠模式。
可选地，AP可以根据预设的休眠时间进行休眠。例如，可以预先设定AP从发送完唤醒帧的时刻开始经过一个时间单元(例如，一个时隙)之后进入休眠状态。或者，AP在休眠通知帧中携带第五指示信息，第五指示信息用于指示AP开始休眠的时间。例如，图7中所示出的，休眠通知帧包括开始休眠时间字段，开始休眠字段用于承载该第五指示信息。开始休眠字段的取值T1表示AP开始休眠的时间，T1的取值可以是相对于休眠通知帧的一个相对时间，也可以是一个绝对的系统时间。或者，如图8中所示出的，休眠通知帧包括开始休眠指示字段，开始休眠指示字段承载该第五指示信息。开始休眠指示字段可以包括一个信息比特，信息比特的值为1时，表示AP在发送完休眠通知帧后立刻进入休眠模式。
进一步地，AP进入休眠状态后，可以经过预设休眠时长之后醒来。或者，AP在休眠通知帧中携带第六指示信息，第六指示信息用于指示AP处于休眠状态的时间长度。例如，图9中所示出的，休眠通知帧中还包括休眠时长字段，休眠时长字段承载第六指示信息，第六指示信息指示AP休眠的时间长度为T2，AP从进入休眠状态开始经过T2时间，又将回到活跃状态。
在上述实施例中，可选地，为了确保所有STA都能够接收到休眠通知帧，AP在进入休眠状态之前，向STA发送多个休眠通知帧。并且，AP可以周期性的向STA发送休眠通知帧，此时休眠通知帧中包括休眠通知帧数目字段，休眠通知帧数目字段携带第七指示信息，第七指示信息用于指示STA在接收完当前的休眠通知帧后，还需要接收多少个休眠通知帧。例如，图10中所示出的，当休眠通知帧数目字段取值为2时，表示后续还需要接收2个休眠通知帧，当休眠通知帧数据字段取值为0时，表示当前接收到的休眠通知帧为最后一个需要接收的休眠通知帧，并且AP在发送完该休眠通知帧后会进入休眠状态。
在本申请实施例中，可选地，AP通过广播的形式向STA发送休眠通知帧，或者以单播的形式向每一个STA发送休眠通知帧。
需要说明的是，当AP进入休眠状态后，AP中的WUR可以是一直打开的，也可以是间歇性的关闭与打开的，为了保证STA在发送唤醒帧的时候WUR是打开的，STA需要知道AP中的WUR的打开时间。
可选地，作为一个例子，AP和STA事先约定当AP处于休眠状态时AP中的WUR的工作模式。STA根据事先约定的工作模式，可以获知AP中的WUR什么时候是打开的。
可选地，作为另一个例子，AP在休眠通知帧中携带第八指示信息，第八指示信息指示在AP处于休眠状态的时间段内，AP中的WUR的工作模式，工作模式包括常打开工作模式和间歇性打开工作模式。
进一步地，当第八指示信息指示当AP处于休眠状态时，AP中的WUR的工作模式 为间歇性打开模式时，休眠通知帧中还携带第九指示信息，第九指示信息指示AP中的WUR处于打开状态的时间段。
举例来说，当AP处于休眠状态时，AP中的WUR是周期性打开的。休眠通知帧包括WUR打开时刻字段、WUR打开时长字段，WUR打开间隔字段中的至少一个字段。例如，图11中所示出的，休眠通知帧包括上述三个字段，其中，WUR打开时刻字段指示WUR打开的起始时间T0，WUR打开时长字段指示WUR打开后持续的时间T1，WUR打开间隔字段指示WUR打开的周期T2。
或者，WUR可以不是周期性打开的，此时休眠通知帧中会携带每次WUR打开的起始时间以及打开后持续的时间。
在上述实施例中，可选地，休眠通知帧可以是Beacon帧或者数据待传指示信息(Delivery Traffic Indication Message，DTIM)Beacon帧。上述的第四指示信息至第九指示信息以信息元素(Information Element，IE)的形式存在于Beacon帧或DTIM Beacon帧中。
可选地，上述第八指示信息或第九指示信息可以承载在802.11ax标准中定义的目标唤醒时间(Target Wake Time，TWT)IE中，并且为了与传统的TWT IE所指示的时间区分开，采用TWT IE中的一个新的Flow ID来表示AP中的WUR的打开时间段。例如，可以采用TWT Flow域的值为3来表示WUR的打开时间段。
进一步地，由于站点只有在AP中的WUR是打开状态的时候发送唤醒帧，AP才能成功接收唤醒帧。由此，为了避免AP中的WUR在刚打开阶段有过多的STA需要竞争信道发送唤醒帧，AP在休眠通知帧中携带竞争窗口大小(Contention Window Size，CW Size)信息，STA在竞争信道发送唤醒帧时，根据CW Size产生一个随机退避值，可以通过设置合适的CW Size有效的分散STA的退避值，降低冲突的发生概率。
在本申请实施例中，可选地，当AP进入休眠状态后，如果STA有上行数据需要发送，STA在向AP发送的唤醒帧中携带缓存区状态报告(Buffer Status Report，BSR)，BSR用于指示STA需要传输的数据的类型以及数据的大小。之后AP向STA发送响应帧，响应帧中携带资源分配信息和/或确认信息。其中，资源分配信息是AP根据BSR确定的，资源分配信息可以具体包括STA发送数据帧时可以使用的时间长度、信道宽度、需要采用的调制编码方式(Modulation and Coding Scheme，MCS)、可以发送的空间流数以及发送功率等信息中的一个或多个信息。确认信息用于指示AP成功接收STA发送的唤醒帧。
可以理解的是，STA在唤醒AP之后，还可以向AP发送控制帧和/或管理帧。
在本申请实施例中，当AP在休眠状态时有下行数据需要发送给STA时，需要根据STA的工作模式将下行数据发送给STA。由此，需要AP知道在AP处于休眠状态时STA的工作模式。可选地，AP可以事先与STA约定在AP处于休眠状态时STA的工作模式。或者，STA通过向AP发送第一工作模式信息帧，向AP汇报在AP处于休眠状态时，STA的工作模式。
具体来说，在AP处于休眠状态时，STA的工作模式主要有三种。工作模式1：STA保持唤醒状态，即STA保持主收发机一直处于打开状态。工作模式2：STA处于休眠状态，STA中的唤醒收发机处于打开状态，可以接收唤醒帧。工作模式3：STA处于传统的802.11系统中的节能状态(Power Save Mode)。相对应的，当AP获知STA的工作模 式为工作模式1时，AP直接将下行数据帧发送给STA。当AP获知STA的工作模式为工作模式2时，AP先向STA发送唤醒帧将STA唤醒后，再向STA发送下行数据帧。当AP获知STA的工作模式为工作模式3时，AP在Beacon中携带STA的业务指示位图(Traffic Indication Map，TIM)信息，等待STA发送PS-POLL帧索取下行数据帧。
在本申请实施例中，可选地，STA向AP发送第二工作模式信息帧，第二工作模式信息帧中携带第二工作模式指示信息，第二工作模式指示信息用于指示在AP处于休眠状态的时间段内AP是否可以向STA发送数据帧。由此，当STA希望获得更好的节能效果时，通过第二工作模式指示信息告知AP不需要在AP处于休眠状态的时间段内醒来向自己发送下行数据。或者，当STA希望获得更低的传输时延时，通过第二工作模式指示信息告知AP可以在AP处于休眠状态的时间段内醒来给STA发送下行数据。
可选地，作为一个例子，上述的第一工作模式信息帧和/或第二工作模式信息帧为关联请求帧，或者上述的第一工作模式信息帧和/或第二工作模式信息帧为新定义的操作模式管理帧。
在本申请实施例中，可选地，当AP被唤醒后，AP通过主收发机向STA发送唤醒声明帧，唤醒声明帧中携带唤醒声明信息，该唤醒声明信息用于指示AP中的主收发机处于唤醒状态。或者可以理解为，唤醒声明信息用于指示AP处于活跃状态。由此，当AP被某个STA唤醒后，AP可以告知其他STA自己已被唤醒，其他STA可以直接向AP发送上行数据，从而降低数据传输的时延。
或者，当多个STA同时竞争信道同时发送唤醒帧时会出现冲突，导致AP无法成功接收到唤醒帧。但是由于唤醒帧的前导(Preamble)部分是相同的信号，多个唤醒帧叠加之后的信号依然具有相同的前导部分。因此AP依然能够检测到唤醒帧的到来，从而获知有STA需要唤醒自己。此时，AP可以主动唤醒主收发机，并向STA发送一个唤醒声明帧。
在本申请实施例中，可选地，当有多个STA都需要唤醒AP时，可以有一个STA作为代表帮助其他STA唤醒AP，这里作为代表的STA是STA簇的簇首或者为中继STA。由此，可以减少唤醒帧的发送数量，提高资源的利用率。
作为一个例子，第一STA确定至少一个第二STA的上行传输需求，之后第一STA向AP中的WUR发送携带数据发送需求信息的唤醒帧，数据发送需求信息用于指示至少一个第二STA的上行传输需求，数据发送需求信息可以是BRS信息。之后AP向第一STA和至少一个第二STA发送包含资源分配信息的触发帧，触发第一STA和至少一个第二STA发送上行数据帧。
具体地，第一STA确定至少一个第二STA的上行传输需求，可以是向至少一个第二STA发送询问帧，询问帧用于询问至少一个第二STA是否有上行传输的需求以及BSR信息。或者可以通过向至少一个第二STA发送触发帧，触发至少一个第二STA向第一STA发送上行传输的需求以及BSR信息。
作为另一个例子，第一STA确定至少一个第二STA的上行传输需求之后，在第一STA与AP通信结束后，告诉AP还有其他STA需要与其进行通信。
具体地，在第一STA向AP发送唤醒帧唤醒AP之后，第一STA向AP中的主收发机发送信息帧，信息帧中携带数据发送需求信息，该数据发送需求信息用于指示至少一个第二STA的上行传输需求。AP接收到第一STA发送的信息帧之后，在一段时间内保 持唤醒状态，等待接收其他STA发送的数据帧。其中，上述一段时间的值可以是标准事先规定的值，也可以是AP通过另外一个信息帧告知STA的值。
在本申请实施例中，可选地，当一个STA结束自己的上行数据帧的传输后，如果传输机会(Transmission Opportunity，TXOP)还没有用完，该STA可以将剩余的传输机会(即剩余的传输时间)授权给其他的STA使用。例如，该STA向另一STA发送授权帧，授权帧中携带TXOP授权信息，该另一STA接收到该授权帧后，可以不用竞争信道，直接根据授权信息进行上行数据的传输。其中，授权信息可以指的是一段时间，由此该另一STA可以直接使用授权信息指示的这一段时间进行上行数据的传输。
在本申请实施例中，当需要发送唤醒帧的站点较多时，多个唤醒帧的发送可能会出现冲突。为了避免冲突的发生，本申请提供了另一唤醒方法。
图12示出了根据本申请另一实施例的唤醒方法，该唤醒方法应用于图1所示的通信系统中，图1所示的通信系统中的接入点包括唤醒收发机WUR和主收发机，如图12所示，方法200包括：
S210，当第一STA确定第二STA向AP中的WUR发送唤醒帧时，第一STA开始进行信道竞争；
S220，当第一STA竞争信道成功时，第一STA通过竞争到的信道向AP发送数据帧。
具体地，当一个STA抢到信道发送唤醒帧时，其他STA保持侦听状态，在侦听到某一个STA发送的唤醒帧后，不需要再发送唤醒帧，直接进行信道竞争，通过竞争到的信道发送上行数据。
可选地，第一STA在确定AP向第二STA发送响应帧时，第一STA开始进行信道竞争，其中，响应帧携带确认信息和/或触发信息，确认信息用于对唤醒帧进行确认，触发信息用于触发第二STA发送数据帧。
进一步地，第一STA在确定第二STA向AP发送唤醒帧时或者第一STA确定AP向第二STA发送响应帧时，第一STA开启定时器。当第一STA竞争到信道时，第一STA确定定时器是否超时，如果没有超时，则在竞争到的信道上发送上行数据，如果定时器超时，第一STA向AP发送唤醒帧，将AP唤醒之后向AP发送上行数据。
可选地，定时器的时可以是标准规定的一个值，也可以是AP通过广播或单播形式发送给该第一STA的。例如，AP发送的响应帧中携带时长信息，第一STA根据时长信息确定定时器的定时时长。
以上结合图3至图12详细描述了根据本申请实施例的唤醒方法。下面将结合图13详细描述根据本申请实施例的站点。该STA应用于通信系统中，该通信系统中包括接入点AP和至少一个STA，该至少一个STA中包括该STA，该AP包括唤醒收发机WUR和主收发机。如图13所示，站点10包括：处理模块11、唤醒收发模块12和主收发模块13；
