  • the present application relates to the field of communications, and in particular, to a wake-up method and apparatus.
  • the IEEE 802.11 working group is preparing to use Low Power Wake Up Receiver (LP-WUR) as the core technology to reduce WiFi (Wireless Fidelity, Wireless Fidelity) 802.11 standard research and development work.
  • LP-WUR Low Power Wake Up Receiver
  • Strategy For example, in the case of a station (Station, STA), when the STA has no message transmission and reception, that is, the No data phase, if the STA continues to monitor the channel (idle listening), it will consume considerable energy. Therefore, the Sleep Schedule is introduced, so that the STA can enter Deep Sleep when there is no data transmission and reception, so as to reduce the energy consumption of the continuous idle listening.
  • the access point (AP) cannot communicate with the STA.
  • the STA Only when the STA wakes up can the communication be between the two, which may cause a certain delay. In order to avoid the high latency caused by the dormancy mechanism, the STA usually wakes up from time to time to check whether there is data to receive, but the STA wakes up from time to time but there is no useful data to send and receive, which is consumed compared to the STA's long sleep. More energy, which will reduce the sleep efficiency of the STA.
  • LP-WUR technology can be adopted.
  • the core idea is that the receiving device (such as STA) adds LP- in addition to the 802.11 main radio in the traditional 802.11 protocol.
  • the WUR part referred to as the WUR part. Specifically, after the STA performs deep sleep, the STA's 802.11 main transceiver module enters deep sleep, but the low-power WUR wake-up starts to work.
  • the AP first sends a WUR wakeup frame to the WUR in the awake state of the STA (Wake Up Packet) , WUP), WUR correctly receives the WUP sent to itself and wakes up the 802.11 main transceiver module in the STA.
  • WUR goes to sleep, and the AP communicates with the awake 802.11 main transceiver module.
  • the 802.11 main transceiver module communicates with the AP, it will go to sleep.
  • the WUR wakes up and starts to listen to whether there is a WUP sent to itself to wake up the 802.11 main transceiver module.
  • the technology uses a low-power WUR instead of the 802.11 main transceiver module to listen to the channel when the medium is idle, and the WUR listening/receiving state consumes 0.1 to 1% of the 802.11 main transceiver module, thus effectively reducing the device idle The waste of energy when listening.
  • WUR In order to achieve low power consumption, WUR requires relatively simple and low complexity in circuit construction and frame structure (WUP) design.
  • the WUR circuit structure may only include energy detection and radio frequency (RF) components, so it is impossible to demodulate some complex modulation methods.
  • the WUP may adopt a simple OOK (On-Off Keying) modulation method, and thus the transmission rate is also low.
  • the AP For the Beacon frame of the traditional 802.11 system, the AP periodically sends a Beacon frame, which carries a large amount of information, including the timestamp, the basic rate of the Basic Service Set (BSS), and the capabilities supported by the AP. Wait. After receiving the Beacon frame, the STA can obtain the status and parameters of the network, determine the working channel, and start data transmission.
  • BSS Basic Service Set
  • the Beacon frame of the 802.11 system supports a lot of functions, its length is also very long. If the WUP still uses the beacon transmission method of the traditional 802.11 system, the transmission rate of the WUP is low. If too much information is carried, it takes a long time for air interface, which is not conducive to network efficiency improvement, and its robustness is also Will decrease.

Description

唤醒方法和装置
本申请要求于2016年10月25日提交中国专利局、申请号为201610940964.3、申请名称为“唤醒方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及唤醒方法和装置。
背景技术
随着WLAN(Wireless Local Area Network，无线局域网)标准的演进，IEEE 802.11工作组正在筹备以低功耗唤醒无线电(LP-WUR，Low Power Wake Up Receiver)为核心技术用以降低WiFi(Wireless Fidelity，无线保真)功耗的802.11标准研究和制定工作。
在WiFi网络中，设备的一大部分能量浪费在无接收信号时的监听(idle listening)，当前传统802.11协议(802.11b/a/g/n/ac等)中相关解决方案集中在优化设备休眠策略。例如以站点(Station，STA)为例，STA没有消息收发时，即No data阶段，若该STA仍持续监听信道(idle listening)，将会消耗可观的能量。因此引入了休眠机制(Sleep Schedule)，使得STA在无数据收发时可以进入深度休眠(Deep Sleep)，以减少持续idle listening的能耗。但是当STA处于深度休眠时，接入点(Access Point，AP)无法与STA通信，只有等到STA苏醒后两者之间才能进行通信，这可能会导致一定的时延(latency)。为了避免休眠机制导致的高时延，STA通常会遵循一定的休眠策略不时醒来检查有无数据需要接收，然而STA不时地苏醒但又没有有用数据需要收发，相较STA的长时间休眠会消耗更多能量，这会降低STA的休眠效率。
因此，为了减少设备idle listening能量浪费，可以采用LP-WUR技术，其核心思想是接收端设备(如STA)除包含传统802.11协议中的802.11主收发模块(802.11main radio)外，新增LP-WUR部分，简称WUR部分。具体地，STA进行深度休眠后，该STA的802.11主收发模块进入深度休眠，但低功耗的WUR苏醒开始工作。如果其他设备，例如AP，需要与该STA进行通信时，带有WUR和802.11主收发模块的接收端设备STA通信时，AP首先给该STA中处于苏醒状态的WUR发送WUR唤醒帧(Wake Up Packet，WUP)，WUR正确收到发给自己的WUP后唤醒STA中的802.11主收发模块，该WUR转入休眠，AP则与苏醒的802.11主收发模块进行通信。当802.11主收发模块与AP通信完成后会进入休眠，同时WUR苏醒又开始侦听是否有发送给自己的WUP，以便唤醒802.11主收发模块。
该技术采用了低功耗的WUR代替802.11主收发模块在媒介空闲时侦听信道，而WUR侦听/接收状态的能耗约为802.11主收发模块的0.1～1％，因此能够有效降低设备idle listening时能量的浪费。
WUR为了实现低功耗，其电路构造、帧结构(WUP)设计等需要较为简单、低复杂度。比如WUR电路结构可能仅仅包含能量检测(energy detect)和射频(RF，radio frequency)部分，因此无法解调一些复杂的调制方式。为此WUP可能采用实现简单的OOK(On-Off Keying，二进制振幅键控)调制方式，因此传输速率也较低。
而对于传统802.11系统的信标(Beacon)帧，AP周期性地发送Beacon帧，里面携带大量的信息，包括时间戳、基础服务集合(Basic Service Set，BSS)的基本速率、AP所支持的能力等。STA接收Beacon帧后，可以获取网络的状态、参数，确定工作信道，从而开始数据传输。
由于802.11系统的Beacon帧支持的功能非常多，因而其长度也很长。若该WUP仍采用传统802.11系统的信标帧(Beacon)的发送方法，WUP的发送速率较低，如果携带太多的信息会占用很长的空口时间，不利于网络效率提升，其稳健性也会降低。
发明内容
本申请提供了一种唤醒方法和装置，提供了一种唤醒帧结构，通过该唤醒帧能够减少接收端设备的能耗。
第一方面，提供了一种唤醒方法，该方法应用于通信系统中，该通信系统中包括发送端设备和至少一个接收端设备，该至少一个接收端设备中的每个接收端设备包括唤醒无线电WUR和主收发机，该方法包括：该发送端设备生成第一唤醒帧，该第一唤醒帧包括WUR标识字段和唤醒字段，该WUR标识字段用于指示目标WUR组中的WUR，该目标WUR组包括该至少一个接收端设备的WUR中的n个WUR，该唤醒字段用于指示该目标WUR组中每个WUR是否执行唤醒操作，该唤醒操作为第一WUR唤醒该第一WUR所在的第一接收端设备中的第一主收发机，该第一WUR为该目标WUR组中任意一个WUR，n为正整数；该发送端设备发送该第一唤醒帧。
因此，本申请实施例的唤醒方法，提供了一种唤醒帧，发送端设备发送该唤醒帧，通过该唤醒帧中的WUR标识字段确定目标WUR组，通过唤醒帧中的唤醒字段指示该目标WUR组中的每个WUR是否执行唤醒操作，唤醒对应的主收发机，从而减少接收端能耗。
结合第一方面，在第一方面的一种实现方式中，该n个WUR的标识为连续的，该WUR标识字段包括起始WUR标识信息，该起始WUR标识信息用于指示连续的该n个WUR中起始WUR的标识。
这样，可以仅仅通过起始WUR的标识，指示n个WUR，减少该唤醒帧长度。
可选地，该n的取值可以由发送端设备预先设置。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该WUR标识字段还包括长度信息，该长度信息用于指示n的值。
应理解，该WUR标识字段包括起始WUR标识信息，用于标识起始WUR，还包括长度信息，用于指示n的取值，则接收端设备可以根据起始WUR和n的值，确定该WUR标识字段指示的目标WUR组中的WUR，从而确定是否属于该目标WUR组。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该WUR标识字段还用于指示该目标WUR组的组标识，在该发送端设备生成该第一唤醒帧之前，该方法还包括：该发送端设备根据预设条件，对该至少一个接收端设备的WUR进行分组并为每 组WUR分配WUR组标识，该预设条件包括：该至少一个接收端设备中每个接收端设备的功耗需求、业务时延需求和业务类型中的至少一个。
该第一唤醒帧中的WUR标识字段指示该目标WUR组的组标识，可以使得该第一唤醒帧通过较短的结构指示出同一组的WUR。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该发送端设备确定第一周期值，该第一周期值用于指示该第一唤醒帧的发送时刻和之后的第二唤醒帧的发送时刻之间的时间间隔，该第二唤醒帧用于指示该目标WUR组中每个WUR是否执行该唤醒操作；该发送端设备根据该第一周期值，发送该第二唤醒帧。
应理解，该发送端设备在第一唤醒帧和第二唤醒帧之间，不会发送其它用于指示该目标WUR组中每个WUR是否执行该唤醒操作的唤醒帧，因此，在第一唤醒帧和第二唤醒帧间隔的时间内，目标WUR组中的WUR可以处于休眠状态，不检测唤醒帧，经过第一周期值的时长后，再检测第二唤醒帧。
应理解，该发送端设备在第一唤醒帧和第二唤醒之间，可以发送其它唤醒帧，该其它唤醒帧用于指示其它WUR是否执行唤醒操作，该其它WUR可以为除了目标WUR组中其它任意WUR。
这样，通过周期性发送相同WUR的唤醒帧，可以使得WUR在没有对应的唤醒帧时，处于休眠状态，进一步减少了WUR的能耗，即减少了接收端设备的能耗。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该第一唤醒帧包括时间信息字段，该时间信息字段用于指示该第一周期值。
应理解，发送端设备可以在第一唤醒帧中至少该第一周期值，则接收端设备的WUR可以根据该第一唤醒帧，确定下一个唤醒帧的发送时刻。同时，发送端设备可以在下一个唤醒帧时修改该第一周期值，使得该第一周期值配置更灵活。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该时间信息字段包括周期信息和个数信息，该周期信息用于指示该发送端设备发送唤醒帧的周期，该个数信息用于指示该第一唤醒帧到该第二唤醒帧之间间隔的唤醒帧的个数。
可选地，该时间信息字段还可以包括时间戳信息，用于指示系统时间，从而可以同步该发送端设备和接收端设备的时间，使得接收端设备接收第二唤醒帧的时间更准确。

由于不同接收端设备对于时延的需求和节能的效果等需求不同，因此，发送端设备可以根据不同接收端设备对于时延和功耗的不同需求，为不同接收端设备确定不同的发送周期值。例如，当第一接收端设备对时延需求较高时，则可以将向该第一接收端设备的第一WUR发送的唤醒帧的周期设置较小；当第一接收端设备对时延需求较低时，则可以将向该第一WUR发送的唤醒帧的周期设置较大。
可选地，发送端设备可以为接收端设备配置一个周期值，即第一周期值，则向该接收端设备发送该第一周期值；该发送端设备还可以为该接收端设备配置多个周期值，则接收端设备可以在该多个周期值中确定第一周期值，并向发送端设备反馈该第一周期值。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该方法还包括：该发送端设备接收该第一接收端设备发送的请求信息，该请求信息用于请求该发送端设备为该第一接收端设备更新周期值；该发送端设备向该第一接收端设备发送第二周期值，该第二周期值用于该第一WUR将该第一唤醒帧的接收时刻与该第二唤醒帧的接收时刻之间的时间间隔更新为该第二周期值；该发送端设备将该第一唤醒帧的发送时刻与该第二唤醒帧的发送时刻之间的时间间隔更新为该第二周期值。
具体地，若第一WUR需要更新第一周期值，则第一接收端设备的第一主收发机可以向发送端设备发送请求信息，该请求信息用于请求发送端设备为该第一WUR更新周期值，可选地，该请求信息还可以包括该第一接收端设备的当前功耗需求和/或业务时延需求。发送端设备根据该请求信息，重新为该第一接收端设备的WUR分配周期值，可选地，该发送端设备可以为该第一接收端设备配置至少一个更新的周期值，由第一接收端设备在该至少一个更新的周期值中确定第二周期值，该第二周期值用于代替第一周期值，即该第二周期值为第一唤醒帧的发送时刻与该第二唤醒帧的发送时刻之间的时间间隔。当接收端设备是在多个周期值中确定第二周期值时，还要向发送端设备反馈该第二周期值，以便于该发送端设备也将第一唤醒帧的接收时刻与该第二唤醒帧的接收时刻之间的时间间隔更新为第二周期值。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该第一周期值与该目标WUR组中的WUR的标识具有对应关系，该方法还包括：在该第一WUR将该第一唤醒帧的发送时刻与该第二唤醒帧的发送时刻之间的时间间隔更新为该第二周期值时，该发送端设备更新该目标WUR组中WUR的标识为该第二周期值对应的WUR标识。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该唤醒操作包括：该第一WUR唤醒该第一主收发机，该第一主收发机接收该发送端设备发送的数据或交付业务指示位图DTIM信标帧。

因此，本申请实施例的唤醒方法，提供了一种唤醒帧，发送端设备发送该唤醒帧，接收端设备的第一WUR可以通过该唤醒帧中的WUR标识字段确定是否属于目标WUR组，再通过唤醒帧中的唤醒字段确定是否执行唤醒操作，唤醒对应的主收发机，从而减少接收端能耗。

具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。。
图1示出了根据本申请实施例的通信系统100的示意图。具体地，该通信系统100可以包括发送端设备和至少一个接收端设备，例如，在图1中，以该通信系统100包括一个发送端设备110和两个接收端设备120和130为例，即该通信系统100中还可以包括其他 接收端设备，该通信系统100中的其他接收端设备都可以与如图1所示的接收端设备120或者130相同。该通信系统100中的发送端设备可以为AP，即发送端设备110可以为AP，在该发送端设备110中包括主收发机111，该主收发机111用于与通信系统100中的接收端设备进行信息交互。该通信系统100中的接收端设备可以为STA，即接收端设备120和接收端设备130可以为STA，每个接收端设备中包括主收发机和WUR，例如，接收端设备120包括主收发机121和WUR 122；接收端设备130包括主收发机121和WUR 132，接收端设备可以通过主收发机或WUR与发送端设备进行信息交互。
本申请实施例的技术方案可以应用于各种通信系统，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)系统、通用分组无线业务(General Packet Radio Service，GPRS)、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)或全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统等。
应理解，在本申请实施例中，AP可以为STA提供接入服务，AP可以是WLAN中的接入点，也可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，还可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(evolved Node B，eNB或e-NodeB)。本申请对此并不作限定。
在本申请实施例中，STA可以是支持WLAN通信协议的各种STA、也可以是GSM或CDMA或WCDMA中的终端(Terminal)、用户设备(User Equipment)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal)等，该站点可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，站点可以是移动电话(或称为“蜂窝”电话)、智能家居、具有移动终端的计算机等，例如，站点还可以是便携式、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音和/或数据。
由于在WiFi网络中，设备的一大部分能量浪费在无接收信号时的监听(idle listening)，因此可以采用LP-WUR技术减少系统能耗。具体地，以发送端设备110和接收端设备120之间的交互为例，在接收端设备120无需与发送端设备110通信时，接收端设备120可以进入深度休眠，即接收端设备120中的主收发机121进入深度休眠，而WUR 122苏醒开始工作。当发送端设备110需要与该发送端设备110通信时，发送端设备110可以向该接收端设备120发送唤醒帧(WUP)，WUR 122接收到发给自己的WUP时，唤醒WUR 122所在的接收端设备120的主收发机121，则主收发机121从深度休眠状态苏醒，进入工作状态，而WUR 122进行休眠状态，发送端设备110则与苏醒进入工作状态的主收发机121进行通信，例如传输数据，并在通信完成后，主收发机121再次进入休眠状态，WUR 122苏醒并开始帧听发送端设备110发送给WUR 122的WUP，以便再次唤醒主收发机121，并依次循环。
应理解，接收端设备120的WUR 122只能唤醒所在的接收端设备120的主收发机121，类似的，接收端设备130的WUR 132只能唤醒主收发机131，因此，本申请实施例中的WUR唤醒主收发机，均表示WUR唤醒该WUR所在的接收端设备的主收发机。
图2示出了根据本申请实施例的唤醒方法200的示意性流程图，该方法200可以应用于通信系统中，该通信系统可以包括发送端设备和至少一个接收端设备，该至少一个接收端设备中的每个接收端设备均包括主收发机和WUR，该通信系统可以为如图1所示的通信系统100。如图2所示，该方法200包括：
S210，发送端设备生成第一唤醒帧，该第一唤醒帧包括WUR标识字段和唤醒字段，该WUR标识字段用于指示目标WUR组中的WUR，该目标WUR组包括通信系统中的至少一个接收端设备的WUR中的n个WUR，该唤醒字段用于指示该目标WUR组中每个WUR是否执行唤醒操作，该唤醒操作为第一WUR唤醒该第一WUR所在的第一接收端设备中的第一主收发机，该第一WUR为该目标WUR组中任意一个WUR。
在本申请实施例中，发送端设备向接收端设备发送唤醒帧，该唤醒帧可以只针对通信系统中包括的至少一个接收端设备中部分接收端设备，再通过另一个唤醒帧指示其他接收端设备，这样可以缩短唤醒帧的大小，保证接收端设备的WUR接收唤醒帧的可靠性。
具体地，发送端设备为每个接收端设备中的WUR配置WUR标识(WUR ID)，发送端设备生成该第一唤醒帧，该第一唤醒帧用于指示通信系统中至少一个接收端设备中n个接收端设备的WUR是否执行唤醒操作，则可以通过第一唤醒帧中的WUR标识字段指示该n个WUR，具体地，该WUR标识字段可以通过WUR ID指示目标WUR组，该目标WUR组即该n个WUR，该n个WUR可以为WUR ID连续的n个WUR，或者也可以为WUR ID不连续的n个WUR。
应理解，本申请实施例中的WUR ID信息可以是WUR完整的网络标识、或简短的网络标识，或其他可以区分不同WUR的信息。
可选地，作为一个实施例，该第一唤醒帧中的WUR标识字段指示的目标WUR组中包括n个WUR，该n个WUR可以为标识连续的n个WUR。具体地，如图3所示，该WUR标识字段可以包括起始WUR标识信息，例如通过起始WUR标识字段指示该WUR标识信息，则对于至少一个接收端设备中的第一接收端设备中的第一WUR，通过该起始WUR标识字段确定起始WUR的标识，再根据n的值，确定该第一WUR是否属于该WUR标识字段指示的目标WUR组，该第一接收端设备为通信系统中至少一个接收端设备中任意一个接收端设备。
例如，n＝5，起始WUR标识字段指示起始WUR的WUR ID为STA 13，则该WUR标识字段指示的目标WUR组包括5个WUR，该5个WUR分别为WUR ID 13-17，即假设第一WUR的WUR ID为15，则该第一WUR属于该目标WUR组；假设第一WUR的WUR ID为19，则该第一WUR不属于该目标WUR组。
可选地，该n的取值可以为预设值。具体地，可以将n的取值设置为固定值，即对于发送端设备发送的多个唤醒帧，每个唤醒帧都类似第一唤醒帧，每个唤醒帧中指示的目标WUR组中n的取值为固定值，例如，可以由标准规定一个固定长度。可选地，还可以由发送端设备预先向接收端设备发送该n的取值，例如，该发送端设备可以为AP，接收端设备为STA，则AP可以通过广播帧向STA发送该n的取值，STA通过主收发机接收确定n的取值，并发送给该STA的WUR。
可选地，该n的取值还可以由该第一唤醒帧确定，即该WUR标识字段还可以包括长度信息，例如通过长度字段指示该长度信息，即通过该长度字段指示该n的值。具体地， 如图4所示，WUR标识字段可以分为两部分，分别为起始WUR标识字段和长度字段，起始WUR标识字段用于指示连续的n个WUR中起始WUR的标识，长度字段用于指示n的取值。则接收端设备的WUR，以第一WUR为例，该第一WUR根据起始WUR与n的值，确定该第一WUR是否属于该目标WUR组。
可选地，作为一个实施例，该第一唤醒帧中的WUR标识字段指示的目标WUR组中包括n个WUR，该n个WUR也可以为标识不连续的n个WUR，而该目标WUR组中的该n个WUR属于同一分组，即该WUR标识字段用于指示WUR组标识，例如，如图5所示，该WUR标识字段可以为WUR组标识字段，即通过该WUR组标识字段指示目标WUR组标识。具体地，发送端设备可以根据接收端设备的预设条件，将通信系统中的至少一个接收端设备的WUR进行分组，并为每组WUR分配组标识。其中，该预设条件可以包括：该至少一个接收端设备中每个接收端设备的功耗需求、业务时延需求和业务类型中的至少一个。
例如，发送端设备可以根据每个接收端设备的业务类型，将业务类型相同的接收端设备分为一组，即业务类型相同的接收端设备的WUR属于同一组，该至少一个接收端设备的WUR可以被分为多组WUR，发送端设备为每组WUR分配组标识，则发送端设备生成的第一唤醒帧，该第一唤醒帧中的WUR标识字段用于指示组标识，即目标WUR组中n个WUR属于同一组，通过WUR标识字段中的组标识确定该组WUR。
再例如，发送端设备还可以根据每个接收端设备对时延的需求的不同进行分组，将时延需求类似的接收端设备分为一组，以便于该组接收端设备获得相同的时延效果。
应理解，该第一唤醒帧还包括唤醒字段，该唤醒字段用于指示目标WUR组中的每个WUR是否执行唤醒操作，该唤醒操作是指WUR唤醒主收发机。具体地，该唤醒字段可以为位图指示字段，例如，图3至图5。该位图指示字段可以为一系列比特序列，每个比特与目标WUR组中每个WUR具有一一对应关系，即一个比特对应于目标WUR组中一个WUR，例如，可以用“1”表示对应的WUR可以执行唤醒操作，“0”表示对应的WUR不执行唤醒操作。
例如，在WUR标识字段指示的n个WUR为4个WUR，分别为WUR 11、12、13和14，则唤醒字段的位图指示字段可以通过4个比特指示该4个WUR是否执行唤醒操作，例如“1011”，则该唤醒字段表示WUR11、13和14执行唤醒操作，而EUR12不执行唤醒操作
在本申请实施例中，为了进一步减少WUR接收唤醒帧的功耗，发送端设备和接收端设备的WUR可以确定第一周期值，根据第一周期值，发送端设备向目标WUR组中的WUR发送唤醒帧，接收端设备的WUR接收该唤醒帧。具体地，发送端设备可以在第一时刻发送第一唤醒帧，该第一唤醒帧用于指示目标WUR组中n个WUR是否执行唤醒操作，以目标WUR组中第一WUR为例，该第一WUR在第一时刻收该第一唤醒帧；发送端设备根据第一周期值，确定第二时刻，在第二时刻发送第二唤醒帧，该第二唤醒帧的结构与第一唤醒帧相同，且该第二唤醒帧用于指示第一唤醒帧中的目标WUR组中n个WUR是否执行唤醒操作，则第一WUR在第二时刻接收该第二唤醒帧。
应理解，该第一WUR第一时刻接收第一唤醒帧后，并确定第一WUR属于第一唤醒帧的WUR标识字段指示的目标WUR组，则该第一WUR可以确定第一周期值，确定在 第二时刻接收第二唤醒帧，则该第一WUR在第一时刻至第二时刻之间可以处于休眠状态，不检测发送端设备的唤醒帧，以便于节省该第一WUR的能耗。
应理解，该发送端设备在发送该第一唤醒帧和第二唤醒帧之间，还可以发送其它唤醒帧，该其它唤醒帧用于指示目标WUR组之外的其它WUR是否执行唤醒操作。
可选地，发送端设备和接收端设备的WUR可以通过第一唤醒帧确定该第一周期值。以图6为例，发送端设备生成第一唤醒帧，该第一唤醒帧可以包括时间信息字段，该时间信息字段用于指示第一周期值。具体地，该时间信息字段指示第一周期值，可以以毫秒(或秒，微秒等)为单位，例如，该时间信息字段可以以秒为单位，该时间信息字段指示1，则表示第一周期值为1秒钟；可选地，该时间信息字段也可以以唤醒帧的个数为单位，例如，时间信息字段可以指示4，而发送端设备发送任意两个时间上连续的唤醒帧的时间为0.5秒，则第一周期值等于4个唤醒的时间，即两秒钟。
可选地，该时间信息字段还可以包括周期信息和个数信息，例如可以通过周期字段指示周期信息，通过个数字段指示个数信息，即时间信息字段可以分为周期字段和个数字段，通过该周期字段和个数字段共同确定该第一周期值，其中，该周期字段用于指示发送端设备发送唤醒帧的周期，个数字段用于指示发送端设备发送第一唤醒帧后，直到发送第二唤醒帧的时刻，发送的唤醒帧的个数。例如，周期字段指示发送端设备发送唤醒帧的周期为0.3秒，个数字段指示4，则当第一时刻发送端设备发送第一唤醒帧后，发送的第四个唤醒帧即为第二唤醒帧，该第二唤醒帧用于指示第一唤醒帧中的目标WUR组中n个WUR是否执行唤醒操作，且发送端设备发送该4个唤醒帧的周期为0.3秒，即第一时刻后的1.2秒为发送第二唤醒帧的第二时刻。
可选地，作为一个实施例，以图6为例，该图6示出了根据本申请实施例的第一唤醒帧的示意图，该第一唤醒帧用于目标WUR组中的WUR确定是否执行唤醒操作，该第一唤醒帧包括WUR标识字段、唤醒字段以及时间信息字段，其中，时间信息字段可以分为时间戳字段、周期字段和个数字段。具体地，时间戳(Timestamp)字段用于指示发送端设备发送该第一唤醒帧的系统时间，以便于接收端设备同步时间；周期字段用于指示发送端设备发送每个唤醒帧的周期，即发送端设备发送任意连续的两个唤醒帧的时间间隔；WUR标识字段用于指示目标WUR组中的WUR，该WUR标识字段可以为如图3至图5中的WUR标识字段；唤醒字段用于指示该目标WUR组中的每个WUR是否执行唤醒操作，该唤醒字段可以为如图3至图5中的唤醒字段；个数字段用于指示发送端设备发送的第二唤醒帧为第几个唤醒帧，例如，当该个数字段指示为4，该第一唤醒帧的WUR标识字段指示WUR10至20，则在发送端发送的第一唤醒帧之后的第四个唤醒帧，即为第二唤醒帧，该第二唤醒帧的WUR标识字段同样指示WUR10至20，该第二唤醒帧用于指示该WUR10至20是否执行唤醒操作，而该第四个唤醒帧的具体发送时刻，则可以根据时间戳字段以及周期字段确定。
可选地，发送端设备和接收端设备WUR还可以预先设置该第一周期值。具体地，发送端设备可以根据接收端设备的功耗需求和/或业务时延需求，确定至少一个周期值，并向接收端设备发送该至少一个周期值，以便于接收端设备在该至少一个周期值中确定第一周期值。另外，当发送端设备为接收端设备配置多个周期值时，接收端设备的主收发机在该多个周期值中确定第一周期值，并向发送端设备反馈该第一周期值。
具体地，以发送端设备为AP，接收端端设备为STA为例。由于不同STA对于时延的需求和节能的效果等需求不同，因此，AP可以根据不同STA对于时延和功耗的不同需求，为不同STA确定不同的发送周期值。例如，当第一WUR对时延需求较高时，则可以将向该第一WUR发送的唤醒帧的周期设置较小；当第一WUR对时延需求较低时，则可以将向该第一WUR发送的唤醒帧的周期设置较大，但本申请实施例并不限于此。
具体地，以发送端设备为第一WUR分配第一周期值为例。发送端设备可以接收第一接收端设备发送的请求信息，该请求信息用于指示该第一接收端设备的功耗需要和/或时延需求。发送端设备根据该请求信息，为该第一接收端设备分配一个或多个周期值，则第一接收端设备的第一主收发机接收至少一个周期值，在该至少一个周期值中确定第一周期值，则第一主收发机向发送端设备发送反馈信息，该反馈信息用于指示该第一周期值，并且该第一主收发机通知第一WUR该第一周期值。
可选地，发送端设备还可以根据为第一WUR分配的周期值，为该第一WUR分配WUR ID，即WUR ID与周期值具有对应关系。例如，WUR ID越小，对应周期值越小。则第一WUR同时确定WUR ID和第一周期值。
在本申请实施例中，发送端设备和第一WUR还可以更新该第一周期值，并且，在WUR ID与第一周期值具有对应关系时，同时也可以对应的更新WUR ID。具体地，发送端设备与第一WUR当前通过第一周期值发送第一唤醒帧和第二唤醒帧，若第一WUR需要更新第一周期值，则第一接收端设备的第一主收发机可以向发送端设备发送请求信息，该请求信息用于请求发送端设备为该第一WUR更新周期值，可选地，该请求信息还可以包括该第一接收端设备的当前功耗需求和/或业务时延需求。发送端设备根据该请求信息，重新为该第一接收端设备的WUR分配周期值，可选地，该发送端设备可以为该第一接收端设备配置至少一个更新的周期值，由第一接收端设备在该至少一个更新的周期值中确定第二周期值，该第二周期值用于更新第一周期值，并向发送端设备反馈该第二周期值，以便于该发送端设备也将该第一周期值更新为第二周期值。当该第一WUR的标识与第一周期值具有对应关系时，在第一WUR将第一周期值更新为第二周期值时，也将WUR ID更新为与第二周期值对应的WUR ID，同样地，发送端设备也会将第一WUR的标识进行更新。
可选地，由于发送端设备在为第一接收端设备的第一WUR配置第一周期值时，可以向第一接收端设备发送至少一个周期值，则当发送端设备向第一接收端设备发送多个周期值时，第一接收端设备在该多个周期值中确定至少两个周期值，该至少两个周期值中包括第一周期值，并向该发送端设备反馈确定的至少两个周期值以及当前使用的第一周期值。在第一接收端设备需要更新该第一周期值时，可以在至少两个周期值中确定第二周期值，并将该第二周期值反馈至发送端设备，发送端设备向第一接收端设备发送响应信息，用于指示发送端设备接受或拒绝该第二周期值，若接受该第二周期值，则发送端设备和第一接收端设备均将第一周期值更新为第二周期值；若拒绝该第二周期值，则发送端设备和第一接收端设备不会将第一周期值更新为第二周期值，则发送端设备和第一接收端设备仍然使用第一周期值，或者，第一接收端设备可以重新选择更新的周期值，再次请求更新周期值，本申请实施例并不限于此。
在本申请实施例中，根据图3至图7，发送端设备生成的该第一唤醒帧包括WUR标 识字段和唤醒字段，还可以包括时间信息字段，可选地，还可以包括其他字段，例如，图8示出了根据本申请实施例的唤醒帧的示意图，该发送端发送的任意唤醒帧均可以为如图8所示。
具体地，如图8所示，该唤醒帧可以包括传统802.11先导(Legacy 802.11preamble)部分，该先导部分包括传统短训练字段(Legacy Short Training Field，L-STF)字段、传统长训练字段(Legacy Long Training Field，L-LTF)字段和传统信令字段(Legacy Signal Field，L-SIG)字段，该先导部分用于周边802.11设备识别该帧结构为唤醒帧，同时，周边802.11设备在一段时间内不会抢占信道，以便于保护该唤醒帧后续部分不被干扰。该唤醒帧还包括唤醒帧的有效载荷字段(payload of wakeup packet)，该部分可以采用二进制振幅键控(On-Off Keying，OOK)调制方式，只有WUR能够识别。该有效载荷字段还可以包括唤醒先导(Wake-Up Preamble)、媒体接入控制(Medium Access Control，MAC)头(MAC Header)、帧载体(frame body)部分和帧校验序列(Frame Check Sequence，FCS)部分。其中，Wake-Up Preamble可以用于WUR识别唤醒帧。MAC Header部分可以用于区分不同的WUR，例如该MAC Header可以为WUR ID。frame body可承载一些其他信息，例如接收端设备的主收发机的信道位置，主收发机被唤醒之后的参数配置，如带宽、天线数等，或者为主收发机被唤醒之后的行为，例如，主收发机被唤醒之后接收发送端设备发送的数据。FCS用于确保收到的数据与发送时的数据一致。
可选地，本申请实施例中第一唤醒帧包括的WUR标识字段和唤醒字段等，可以位于frame body部分。
S220，发送端设备向接收端设备发送该第一唤醒帧。
应理解，该发送端设备可以通过广播的方式发送该第一唤醒帧，接收端设备通过WUR接收该第一唤醒帧，即该通信系统中的接收端设备的WUR均可以接收该第一唤醒帧，通过该第一唤醒帧中的WUR标识字段，确定是否执行唤醒操作。
例如，对于第一WUR，该第一WUR为该WUR标识字段中指示的目标WUR组中任意一个WUR，则该第一WUR接收该第一唤醒帧，确定属于目标WUR组，则可以继续执行S230；对于第二WUR，该第二WUR不属于该WUR标识字段中指示的目标WUR组，则该第二WUR接收到该第一唤醒帧后，不继续执行S230，可以忽略该第一唤醒帧。
S230，第一WUR接收第一唤醒帧，根据该第一唤醒帧中的WUR标识字段确定该第一WUR属于目标WUR组，再根据该第一唤醒帧中的唤醒字段，确定是否执行唤醒操作，该唤醒操作指该第一WUR唤醒第一主收发机。
应理解，第一WUR唤醒第一主收发机是指使得主收发机从当前的休眠状态转为工作状态，而该第一WUR进入休眠状态。当第一主收发机处于工作状态时，该主收发机可以与发送端设备进行通信，例如可以接收发送端设备发送的数据，或向发送端设备发送数据。
可选地，第一主收发机被唤醒后，处于工作状态还可以接收发送端设备发送的交付业务指示位图(Delivery traffic indication map，DTIM)信标帧，在DTIM信标帧之后，发送端设备会向接收端设备发送广播多播帧。
可选地，在第一WUR接收的第一唤醒帧中还可以包括时间字段，根据该时间字段，第一WUR确定唤醒第一主收发机的时刻。具体的，第一WUR接收第一唤醒帧，当该第一唤醒帧的唤醒字段指示该第一WUR唤醒第一主收发机时，第一WUR还可以根据该第 一唤醒帧中的时间字段确定唤醒第一主收发机的时刻，例如，该时间字段可以指示该第一WUR立刻唤醒第一主收发机，则第一WUR收到该第一唤醒帧后，唤醒第一主收发机，该第一主收发机从休眠状态苏醒，变为工作状态，接收发送端设备发送的数据或DTIM信标帧，而第一WUR进入休眠状态；该时间字段还可以指示目标时刻，则第一WUR接收到该第一唤醒帧后，根据时间字段确定目标时刻，在目标时刻唤醒第一主收发机，该第一主收发机从休眠状态苏醒，变为工作状态，接收发送端设备发送的数据或DTIM信标帧，而第一WUR进入休眠状态。
因此，本申请实施例的唤醒方法，发送端设备向接收端设备发送唤醒帧，该唤醒帧包括WUR标识字段和唤醒字段，根据WUR标识字段确定目标WUR组，根据唤醒字段确定目标WUR组中的WUR是否需要执行唤醒操作，该唤醒帧结构较短，另外，发送端设备周期性发送目标WUR组对应的唤醒帧，可以使得WUR在不需要接收唤醒帧时进入休眠状态，节省该WUR的能耗。
可选地，作为一个实施例，图9示出了根据本申请另一实施例的唤醒方法300的示意性流程图。该方法300可以应用于通信系统中，该通信系统可以包括发送端设备和至少一个接收端设备，该至少一个接收端设备中的每个接收端设备均包括主收发机和WUR，该通信系统可以为如图1所示的通信系统100。如图9所示，该方法300包括：
S310，发送端设备生成唤醒帧，该唤醒帧包括WUR组标识字段，该WUR组标识字段用于指示目标WUR组中的WUR，该目标WUR组包括该至少一个接收端设备的WUR中的m个WUR，该唤醒帧用于指示该目标WUR组中每个WUR执行唤醒操作，该唤醒操作为第一WUR唤醒该第一WUR所在的第一接收端设备中的第一主收发机，该第一WUR为该目标WUR组中任意一个WUR。
在本申请实施例中，发送端设备可以根据预设条件将通信系统中的至少一个接收端设备的WUR进行分组，并为每组WUR分配组标识，其中，该预设条件可以包括：该至少一个接收端设备中每个接收端设备的功耗需求、业务时延需求和业务类型中的至少一个。
例如，发送端设备可以根据每个接收端设备的业务类型，将业务类型相同的接收端设备分为一组，即业务类型相同的接收端设备的WUR属于同一组，该至少一个接收端设备的WUR可以被分为多组WUR，发送端设备为每组WUR分配组标识，则发送端设备生成的唤醒帧，该唤醒帧中的WUR组标识字段用于指示需要被唤醒的目标WUR组的组标识，该目标WUR组中可以包括至少一个接收端设备的WUR中的m个WUR。
再例如，发送端设备还可以根据每个接收端设备对时延的需求的不同进行分组，将时延需求类似的接收端设备分为一组，以便于该组接收端设备获得相同的时延效果。具体的，以发送端设备为AP，接收端端设备为STA为例。由于不同STA对于时延的需求和节能的效果等需求不同，因此，AP可以根据不同STA对于时延和功耗的不同需求，对不同STA进行分组。例如，发送端设备可以将对时延需求较高的WUR分为同一组，则向该组WUR发送的唤醒帧的周期较短；发送端设备还可以将对时延需求较低的WUR分为同一组，则向该组WUR发送的唤醒帧的周期较长，但本申请实施例并不限于此。
S320，发送端设备向目标WUR组中的WUR发送该唤醒帧，例如，对于该目标WUR组中的第一WUR，该第一WUR接收唤醒帧，该第一WUR为目标WUR组中的任意一个WUR。
应理解，该发送端设备可以通过广播的方式发送该唤醒帧，接收端设备通过WUR接收该唤醒帧，即该通信系统中的接收端设备的WUR均可以接收该唤醒帧，通过该唤醒帧中的WUR组标识字段，确定是否执行唤醒操作。
例如，对于第一WUR，该第一WUR确定所在组的组标识为该WUR组标识字段中指示的目标WUR组，则该第一WUR接收该唤醒帧，确定属于目标WUR组，则可以继续执行S330；对于第二WUR，该第二WUR确定所在组的组标识不属于该WUR标识字段中指示的目标WUR组，则该第二WUR接收到该唤醒帧后，不继续执行S330，可以忽略该唤醒帧。
S330，属于唤醒帧指示的目标WUR组的该第一WUR执行唤醒操作，唤醒第一主收发机。
应理解，第一WUR唤醒第一主收发机是指使得主收发机从当前的休眠状态转为工作状态，而该第一WUR进入休眠状态。当第一主收发机处于工作状态时，该主收发机可以与发送端设备进行通信，例如可以接收发送端设备发送的数据，或向发送端设备发送数据，或者接收发送端设备发送的DTIM帧。
可选地，该唤醒帧还可以包括时间字段，该时间字段用于指示该目标WUR组中的WUR唤醒对应主收发机的时刻。
应理解，S330中第一WUR唤醒第一主收发机的操作，与S230中第一WUR唤醒第一主收发机的操作类似，在此不再赘述。
因此，本申请实施例的唤醒方法，发送端设备向接收端设备发送唤醒帧，该唤醒帧包括WUR组标识字段，该WUR组标识字段用于指示目标WUR组，该目标WUR组中的WUR根据该唤醒帧，唤醒对应的主收发机，可以使用较短的唤醒帧结构唤醒多个WUR。
可选地，作为一个实施例，图10示出了根据本申请再一实施例的唤醒方法400的示意性流程图。该方法400可以应用于通信系统中，该通信系统可以包括发送端设备和至少一个接收端设备，该至少一个接收端设备中的每个接收端设备均包括主收发机和WUR，该通信系统可以为如图1所示的通信系统100。如图10所示，该方法400包括：
S410，发送端设备生成唤醒帧，该唤醒帧用于指示该至少一个接收端设备中的WUR执行唤醒操作，该唤醒操作包括：第一接收端设备的第一WUR在目标时刻唤醒该第一接收端设备的第一主收发机接收发送端设备发送的DTIM信标帧，第一接收端设备为至少一个接收端设备中任意一个接收端设备。
应理解，该发送端设备可以向多个接收端设备发送唤醒帧，该唤醒帧用于指示该多个接收端设备中的至少一个接收端设备接收该唤醒帧，并根据该唤醒帧确定执行唤醒操作。
应理解，该唤醒帧用于指示WUR主收发机接收DTIM信标帧，该唤醒帧的结构可以为本申请实施例中唤醒方法100、方法200和方法300中任意一种唤醒帧的结构，或者还可以为其它唤醒帧结构，本申请实施例并不限于此。
S420，该发送端设备向该至少一个接收端设备的WUR发送该唤醒帧。
应理解，发送端设备生成针对至少一个接收端设备的WUR的唤醒帧，并向该至少一个接收端设备发送该唤醒帧。对于该至少一个接收端设备中的第一接收端设备的第一WUR，该第一WUR接收该唤醒帧，确定执行唤醒操作，继续执行S430，该第一接收端设备为该至少一个接收端设备中任意一个接收端设备；对于不属于该至少一个接收端设备 中的第二接收端设备中的第二WUR，也可以接收该唤醒帧，但该第二WUR不属于该唤醒帧指示的至少一个接收端设备的WUR，则该第二WUR可以不进行任何操作，忽略该唤醒帧。
S430，至少一个接收端设备的WUR根据该唤醒帧，执行唤醒操作，该唤醒操作包括：第一接收端设备的第一WUR在目标时刻唤醒该第一接收端设备的第一主收发机接收发送端设备发送的DTIM信标帧，第一接收端设备为至少一个接收端设备中任意一个接收端设备。
应理解，在S420中，第一WUR确定执行唤醒操作，则在S430中，第一WUR执行唤醒操作，在目标时刻唤醒主收发机，以便于主收发机接收发送端设备发送的DTIM信标帧。
在本申请实施例中，发送端设备会在目标时刻向接收端设备发送DTIM信标帧，因此，接收端设备的WUR需要在目标时刻唤醒主收发机。具体地，第一WUR接收该唤醒帧，该唤醒帧可以包括时间字段，根据该时间字段确定目标时刻，以便于第一WUR在目标时刻唤醒第一主收发机接收DTIM信标帧。
可选地，当该时间字段指示的目标时刻为第一WUR接收该唤醒帧的时刻时，第一WUR在接收到该唤醒帧后，立即唤醒第一主收发机接收DTIM信标帧；当该时间字段指示经过一段时长之后的目标时刻时，则第一WUR在接收到该唤醒帧时，不立即唤醒第一主收发机，而是在该目标时刻时，唤醒第一主收发机接收DTIM信标帧。
可选地，唤醒帧还可以不包括该时间字段，根据预设时间确定目标时刻。具体地，当唤醒帧不包括时间字段时，可以表示第一WUR在接收到该唤醒帧后，立即唤醒第一主收发机接收DTIM信标帧，或者也可以表示，在经过预设时间后，唤醒第一主收发机接收DTIM信标帧。其中，该预设时间可以由发送端设备和接收端设备预先设置成固定时长，本申请实施例并不限于。
S440，发送端设备在目标时刻向第一接收端设备发送DTIM信标帧，具体的，可以通过该第一接收端设备的第一主收发机接收该DTIM信标帧。
应理解，第一WUR在目标时刻唤醒第一主收发机，则在目标时刻发送端设备向第一接收端设备发送DTIM信标帧，通过该第一接收端设备的第一主收发机接收该DTIM信标帧，而第一WUR在目标时刻后休眠，直到第一接收端设备与发送端设备之间无需通信，第一主收发机进入休眠，则第一WUR被唤醒。
应理解，发送端设备在发送DTIM信标帧后，会向接收端设备继续发送广播多播帧，因此，主收发机在被唤醒后，可以接收到DTIM信标帧，进而还可以接收到后续的广播多播帧。
因此，本申请实施例的唤醒方法，通过唤醒帧唤醒接收端的主收发机，以便于该主收发机在发送端设备发送DTIM信标帧时，接收到该DTIM信标帧，进而保证主收发机可以接收到DTIM信标帧后续的广播多播帧，节省接收端设备的能耗。
