Description

通信方法、网络设备和终端 技术领域
本发明涉及无线通信领域，尤其涉及一种通信方法、网络设备和终端。
背景技术
随着WLAN(英文：Wireless Local Area Network，无线局域网)标准的演进，在无线保真(英文：Wireless Fidelity，WiFi)网络中，终端设备(如工作站)在没有消息收发时(如No data阶段)，会有很大一部分能量浪费在无接收信号时的空闲时侦听信道中。IEEE(英文：Institute of Electrical and Electronic Engineers，电气和电子工程师协会)802.11工作组正在筹备以低功耗唤醒接收机(英文：Low Power Wake Up Radio/Low Power Wake Up Receiver，LP-WUR，也叫wake up radio)(以下简称WUR)为核心技术来降低WiFi功耗。由此可见，在WiFi网络中的网络设备，如无线接入点(英文：Access Point，AP)与终端的通信过程中，需要一种降低终端设备功耗的通信方法。
现有技术对于降低终端设备功耗的通信方法是通过终端采用低功耗的WUR代替802.11主收发模块在媒介空闲时侦听信道。如图1所示，当接收端的终端的802.11主收发模块进入深度休眠后，低功耗的WUR苏醒开始工作。当发送端的AP需要与带有WUR和802.11主收发模块的终端通信时，AP的802.11主收发模块向终端的WUR发送唤醒帧或唤醒包(英文：Wake Up Packet，WUP)，收到WUP的WUR将WUP中的WUR ID(即WUR标识信息，用于识别WUR)与自己被分配的WUR ID进行比对，如果比对结果一致则WUR认为该WUP是发给自己的，然后WUR唤醒终端的802.11主收发模块，WUR再转入休眠，终端的802.11主收发模块被唤醒后，向AP的802.11主收发模块发送唤醒确认帧，以指示终端的802.11主收发模块被成功唤醒，之后AP的802.11主收发模块与苏醒的终端的802.11主收发模块进行通信。终端的802.11主收发模块与AP的802.11主收发模块通信完成后会进入休眠，同时终端的WUR又开始侦听是否有发送给自己的WUP，以便再次唤醒终端的802.11主收发模块。
然而，终端使用802.11帧格式向AP的802.11主收发模块发送唤醒确认帧，也就是说，AP的802.11主收发模块需要一直开启，等待接收该唤醒确认帧，这种情况的耗电量较大，尤其当唤醒过程失败时，由于较长时间接收不到唤醒确认帧，导致耗电程度加大。
发明内容
本申请实施例提供了一种通信方法、接入点和终端，通过以唤醒包的方式响应收到的唤醒包，有效的降低通信过程中的功耗,较少信令开销，从而有效的缩短了通信时间。
第一方面，提供了一种通信方法，该方法可以包括：当第一设备(第一终端)有数据要发送给第二设备(网络设备，如AP)，即第一设备要进行上行通信时，第一设备需要生成第一唤醒包。第一设备向第二设备的唤醒接收机WUR发送第一唤醒包，以唤醒第二设 备的主收发模块。第一唤醒包可以包括第二设备的WUR标识信息，如WUR的地址信息，以用于指示第二设备接收该第一唤醒包。第一设备的WUR接收第二唤醒包，以用于对第一唤醒包进行响应，第二唤醒包由第二设备发送。
其中，通过初始化第二设备的通信规定，即规定第二设备在接收到唤醒包后，以唤醒包的方式对接收到的唤醒包进行响应，进而使第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信。该通信方法中第二设备在收到第一唤醒包后，通过向第一设备的WUR发送第二唤醒包，降低了第一设备的整体能耗，该方法可应用于AP至终端、终端至终端，以及终端至AP的多个场景。提高了AP与终端间无线通信的灵活性。
在一个可选的实现中，第一唤醒包包括唤醒指示信息，唤醒指示信息用于指示第二设备用唤醒包的方式对第一唤醒包进行响应，以使第二设备对第一唤醒包进行确认，即确认第二设备收到了第一唤醒包，或者说确认第二设备的WUR已经把第二设备的主收发模块唤醒，即处于ON工作状态。
在一个可选的实现中，唤醒指示信息包括第一设备的WUR的工作状态信息，第一设备的WUR接收第二唤醒包，第二唤醒包由第二设备发送，具体包括：第一设备的WUR接收第二设备根据第一设备的WUR的工作状态信息发送的第二唤醒包。
也就是说，第二设备可以根据第一设备的WUR的工作状态信息，选择用唤醒包的方式对第一唤醒包进行响应，还是用除唤醒包外的其他的方式对第一唤醒包进行响应，提高了通信方法的灵活性。
当第一设备的WUR处于工作状态时，第一设备的WUR接收第二设备根据唤醒指示信息发送的第二唤醒包，也就是说，当第二设备了解到第一设备的WUR为ON状态时，确认以唤醒包的方式反馈响应，从而降低了第一设备的功耗，同时也缩短了通信时间。
在一个可选的实现中，第二唤醒包包括接收设备的WUR标识信息，如WUR的ID或WUR的接收地址。第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，具体包括：第一设备将第一设备的WUR标识信息与接收设备的WUR标识信息进行匹配；当第一设备的WUR标识信息与接收设备的WUR标识信息匹配时，第一设备确定第二设备的属性信息，并通过第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，即隐式地，使第一设备接收到该第二唤醒包，有效的降低通信过程中的功耗。
在一个可选的实现中，第二唤醒包包括第二设备的发送地址信息，第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，具体包括：第一设备根据第二设备的发送地址信息，通过第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，即显式地，用一种方式使第一设备接收到该第二唤醒包，有效的降低通信过程中的功耗。
在一个可选的实现中，第二唤醒包包括数据传输方向信息，第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，具体包括：第一设备根据数据传输方向信息，通过第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，即显式地，用另一种方式使第一设备接收到该第二唤醒包，有效的降低通信过程中的功耗。
在一个可选的实现中，第二唤醒包包括第二设备的小区的标识信息，第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，具体包括：第一设备根据第二设备的小区的标识信息，通过第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，即显式地，用再一种方式使第一终端接收到该第二唤醒包，有效的降低通信过程中的 功耗。
在一个可选的实现中，第二唤醒包还包括第一指示信息，第一指示信息用于指示第二设备的主收发模块已被唤醒，以使第二设备关联的除第一设备以外的至少一个第三终端根据第一指示信息，通过至少一个第三设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，由于第一指示信息向与至少一个第二终端指示自己的主收发模块已被唤醒，减少了第三设备向第二设备发唤醒包的信令开销，从而降低了第三设备的信令开销，有效的缩短了通信时间。
在一个可选的实现中，第二唤醒包还包括广播地址，以使所述第一设备的WUR与所述至少一个第三设备的WUR接收所述第二唤醒包，并分别通过第一设备的主收发模块和至少一个第三设备的主收发模块与唤醒后的第二设备的主收发模块进行通信。由于该第二唤醒包增添了广播地址，使所有终端都可以知道第二设备的主收发模块已被唤醒，这样减少了第三设备向第二设备发唤醒包的信令开销，从而降低了第三设备的信令开销，有效的缩短了通信时间。
在一个可选的实现中，在第二唤醒包包含广播地址的基础上，第二唤醒包可以不包含第一设备的WUR标识信息(如WUR的ID或WUR接收地址)，此时，通过设置第一设备只要收到第二设备发送的第二唤醒包即可认为第二唤醒包收到了第一唤醒包，这样可以减少第二唤醒包的长度，有效缩短传输时间。
在一个可选的实现中，第二唤醒包还包括第一时长，第一时长为第二设备的主收发模块的工作时长，第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，具体包括：第一设备根据第一时长，通过第一设备的主收发模块与第二设备的主收发模块进行通信。也就是说，在第一时长内，第二设备的主收发模块可以正常通信，不需要被第二设备的WUR再次唤醒，减少了信令开销，缩短了通信时间。
在一个可选的实现中，第二唤醒包还包括第二指示信息，第二指示信息用于唤醒第二设备关联的至少一个第四设备主收发模块，以使第一设备的主收发模块和至少一个第四设备的主收发模块，分别与第二设备的主收发模块进行通信。第二唤醒包中的第二指示信息，不仅唤醒了第四设备的主收发模块，还对第一设备进行了响应，也就是说，第二指示信息减少了第四设备与第二设备间的信令开销，有效的缩短了通信时间。
在一个可选的实现中，第二唤醒包还包括至少一个第四设备的WUR标识信息，以使至少一个第四设备的WUR接收第二唤醒包，并根据至少一个第四设备的WUR标识信息，唤醒至少一个第四设备的主收发模块，通过唤醒后的至少一个第四设备的主收发模块与唤醒后的第二设备的主收发模块进行通信。
第二方面，提供了一种通信方法，该方法可以包括：当第一设备(第一终端)有数据要发送给第二设备(网络设备，如AP)，即第一设备要进行上行通信时，第二设备的唤醒接收机WUR接收第一设备发送的第一唤醒包。第二设备的WUR根据第一唤醒包，唤醒第二设备的主收发模块。第二设备向第一设备的WUR发送第二唤醒包，以用于对第一唤醒包进行响应。唤醒后的第二设备的主收发模块与第一设备的主收发模块进行通信。其中，该通信方法中第二设备在收到第一唤醒包后，通过向第一设备的WUR发送第二唤醒包，降低了第一设备的整体能耗，该方法可应用于AP至终端、终端至终端，以及终端至AP的多 个场景。提高了AP与终端间无线通信的灵活性。
在一个可选的实现中，第一唤醒包包括唤醒指示信息，唤醒指示信息用于指示第二设备以唤醒包的形式对第一唤醒包进行响应，以使第二设备对第一唤醒包进行确认，即确认第二设备收到了第一唤醒包，或者说确认第二设备的WUR已经把第二设备的主收发模块唤醒，即处于ON工作状态。
在一个可选的实现中，唤醒指示信息包括第一设备的WUR的工作状态信息，第二设备向第一设备发送第二唤醒包，具体包括：第二设备根据第一设备的WUR的工作状态信息，向第一设备的WUR发送第二唤醒包。当第一设备的WUR处于工作状态时，第一设备根据唤醒指示信息，向第二设备的WUR发送第二唤醒包。
也就是说，第二设备可以根据第一设备的WUR的工作状态信息，选择用唤醒包的方式对第一唤醒包进行响应，还是用除唤醒包外的其他的方式对第一唤醒包进行响应，提高了通信方法的灵活性。降低了第一设备的功耗，同时也缩短了通信时间。
在一个可选的实现中，第二唤醒包包括接收设备的WUR标识信息，以使第一设备将第一设备的WUR标识信息与接收设备的WUR标识信息进行匹配，当第一设备的WUR标识信息与接收设备的WUR标识信息匹配时，第一设备确定第二设备的属性信息，并通过第一设备的主收发模块与唤醒后的第二设备的主收发模块进行通信，即隐式地，使第一设备接收到该第二唤醒包，有效的降低通信过程中的功耗。

在一个可选的实现中，第二唤醒包还包括广播地址，以使第一设备与至少一个第三设备接收第二唤醒包，并分别通过第一设备的主收发模块和至少一个第三设备的主收发设备与唤醒后的第二设备进行通信，由于该第二唤醒包增添了广播地址，使所有终端都可以知道第二设备的主收发模块已被唤醒，这样减少了第三设备向第二设备发唤醒包的信令开销，从而降低了第三设备的信令开销，有效的缩短了通信时间。
在一个可选的实现中，第二唤醒包还包括第一时长，第一时长为所述第二设备的主收发模块的工作时长，以使第一设备根据所述唤醒确认指示信息和第一时长，通过第一设备的主收发模块与唤醒后的第一设备的主收发模块进行通信。

具体实施方式
下面通过附图和实施例，对本申请的技术方案做进一步的详细描述。
本发明描述的技术可以适用于长期演进(英文：Long Term Evolution,LTE)系统，或其他采用各种无线接入技术的无线通信系统，例如采用码分多址，频分多址，时分多址，正交频分多址，单载波频分多址等接入技术的系统。此外，还可以适用于使用LTE系统后 续的演进系统，如第五代5G系统或新空口(英文：new radio，NR)系统等。需要说明的是，本发明中的名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。
本发明提供的通信方法可以应用于WLAN系统中，如图2所示，该WLAN系统可以包括至少一个终端和网络设备。
终端可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备(英文：wearable device，WD)、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(英文：user equipment,UE),移动台(英文：mobile station,MS)，终端(英文：terminal)，终端设备(英文：terminal equipment)，站点(英文：Station，STA)等等。
网络设备是一种部署在无线接入网中用以为终端提供无线通信功能的设备，网络设备可以包括各种形式的宏基站，微基站，中继站，接入点(包括开启热点功能的终端)等等。为方便描述，本发明中上述提供无线通信功能的网络设备可以统称为接入点AP。
在图2中，终端STA1与终端STA2都可以包括主收发模块(如802.11主收发模块)和WUR，其中，STA1与STA2的功能可以相同也可以不同，如STA1可以具有WiFi热点功能，STA2可以不具有该功能。值得说明的是，为了降低设备能耗，该AP也可以配置WUR。
AP、STA1和STA2三者间可以相互进行无线通信，即AP可以分别与STA1和STA2进行无线通信、STA1和STA2间可以进行无线通信。
场景一，当AP有数据进行下行通信时，AP可以向STA1和/或STA2的WUR发送第一唤醒包，唤醒STA1和/或STA2的主收发模块，唤醒后的STA1和/或STA2向AP的WUR发送第二唤醒包，以用于对第一唤醒包进行响应，也就是说，第二唤醒包是第一唤醒包的确认包。AP的WUR接收到第二唤醒包后，与唤醒后的STA1和/或STA2的主收发模块进行数据通信。
场景二，当STA1和/或STA2有数据进行上行通信时，STA1和/或STA2向AP发送第一唤醒包，唤醒AP的主收发模块，唤醒后的AP向STA1和/或STA2的WUR发送第二唤醒包，以用于对第一唤醒包进行响应。STA1和/或STA2的WUR接收到第二唤醒包后，与唤醒后的AP的主收发模块进行数据通信
场景三，当STA1开启热点功能时，STA1可以向STA2的WUR发送第一唤醒包，唤醒STA2的主收发模块，唤醒后的STA2向AP的WUR发送第二唤醒包，以用于对第一唤醒包进行响应。STA1的主收发模块接收到第二唤醒包后，与唤醒后的STA2进行数据通信。
需要说明的是，STA1或STA2可以通过STA1或STA2的主收发模块发送第二唤醒包(即将主收发模块发送的数据调整为WUR帧格式的数据)，也可以通过STA1或STA2中配置具有WUR帧格式的独立发送器发送第二唤醒包，还可以通过其他方式发送第二唤醒包，本发明在此不做限定。
由于WUR工作时的能耗远远低于主收发模块工作时的能耗，由此可知，等待反馈的终端或AP开启WUR，接收第二唤醒包(响应)的能耗最少，从而整体降低了系统能耗。
在一种移动AP的应用场景中，STA1可以开启热点功能作为移动AP提供WiFi热点，此时需要考虑STA1的能耗。具体地，配置了WUR的该移动AP可以预置某一时间段关闭(OFF)主收发模块，开启(ON)WUR。
相应地，当该移动AP处于主收发模块OFF，WUR ON的工作状态时，关联在该移动AP下的非AP站点(STA2)与该移动AP进行上行(英文：uplink)通信时，非AP站点需要先发送唤醒包(英文：wake up packet)，该移动AP的WUR收到该wake up packet后，唤醒自己的主收发模块，并以唤醒包的方式进行响应，从而准备服务本小区的非AP站点。这里说的服务，包括接收非AP站点发送的上行数据(不仅限于数据帧，还可以是管理帧或控制帧)，也包括移动AP给非AP站点发送下行数据。
图3为本发明实施例提供的一种WLAN系统结构示意图。如图3所示，该WLAN系统可以包括第一设备和第二设备。
第一设备可以是图2中的AP或STA，相应的，第二设备可以是图2中的STA或AP。第一设备向第二设备的WUR发送第一唤醒包，第二设备的WUR接收到第一唤醒包后，第二设备的WUR向第二设备的主收发模块发送触发信号，以用于唤醒第二设备的主收发模块。
第二设备向第一设备的WUR发送第二唤醒包，以用于对第一唤醒包进行响应，使第一设备确认第二设备的主收发模块已被唤醒。第一设备的主收发模块向第二设备的主收发模块发送数据，以进行通信。
下面以场景二，第一设备为第一终端STA，第二设备为AP为例，进行详细介绍。
图4为本发明实施例提供的一种通信方法的信令交互图。如图4所示，该方法可以包括：
步骤410、第一终端生成第一唤醒包。
当第一终端有数据要发送给AP，即第一终端要进行上行通信时，第一终端生成第一唤醒包，以用于确认AP的主收发模块(如802.11主收发模块)的工作状态为ON状态。
步骤420、第一终端向AP的唤醒接收机WUR发送第一唤醒包，以唤醒AP的主收发模块。
第一唤醒包可以包括AP的WUR标识信息，如WUR的地址信息，以用于指示AP接收该第一唤醒包。该WUR标识信息可以是完整的WUR标识信息或部分的WUR标识信息，如完整的媒体介入控制(英文：Medium Access Control，MAC)地址，或能区分MAC地址的部分地址。
可选地，第一唤醒包还可以包括唤醒指示信息，该唤醒指示信息用于指示AP用唤醒包的方式对第一唤醒包进行响应，该响应可以作为对第一唤醒包的一种唤醒确认，所述“唤醒确认”，可以指确认AP收到了第一唤醒包，或者说确认AP的WUR已经把AP的主收发模块唤醒，即处于ON工作状态。
图5为一种唤醒包的结构示意图。如图5所示，该唤醒包可以包括传统802.11的前导(英文：preamble)域和载荷(英文：payload)域。
在一个例子中，结合图5的结构，唤醒指示信息可以占用载荷域中的1个比特(bit)位，即用1比特的值表示，其值为1可以指示AP用唤醒包的方式对第一唤醒包进行响应，其值为0可以指示AP用除唤醒包外的其他的方式对第一唤醒包进行响应；
或者，其值为0可以指示AP用唤醒包的方式对第一唤醒包进行响应，其值为1可以指示AP用除唤醒包外的其他的方式对第一唤醒包进行响应，如AP用AP的主收发模块向第一终端发送唤醒确认包，该确认包为非WUR帧格式。
可以理解的是，根据实际设计需要，唤醒指示信息在载荷域中也可以占用多个比特位，用多个比特值的组合来表示指示AP用唤醒包的方式对第一唤醒包进行响应，本发明实施例在此不做限定。
可选地，唤醒指示信息可以包括第一终端的WUR和/或主收发模块(英文：main radio)的工作状态信息。
若第一终端的WUR OFF，main radio ON，则AP应该用主收发帧(英文：main radio frame)格式回复唤醒确认，若第一终端的WUR ON，main radio OFF，则AP应该用WUR帧格式(唤醒包的方式)回复唤醒确认。也就是说，AP可以根据第一终端的WUR的工作状态信息，选择用唤醒包的方式对第一唤醒包进行响应，还是用除唤醒包外的其他的方式对第一唤醒包进行响应，从而降低了第一终端的功耗，同时也缩短了通信时间。
其中，第一终端的WUR的工作状态信息和主收发模块的工作状态信息在载荷域中可以用新建的第一字段来承载；也可以复用第一唤醒包中的其他字段(如预留字段等)来承载，为表述方便此方式占用的字段也称为第一字段。
可选地，第一字段可以包含1bit，例如，0指示第一终端的WUR ON，main radio OFF；1指示第一终端的WUR OFF，main radio ON。
可替代地，第一字段还可以包含2bit，例如，00指示第一终端的WUR OFF，main radio OFF，01指示WUR OFF，main radio ON，10指示WUR ON，main radio OFF，11指示WUR ON，main radio ON。
可以理解的是，上述第一字段包含的比特位数与具体指示内容的映射仅为举例说明，根据实际需要，第一字段包含的比特位数与具体指示内容还可以有其他形式的映射，本发明实施例在此不做限定。
步骤430、AP根据第一唤醒包向第一终端发送第二唤醒包，以用于对第一唤醒包进行响应。
在执行步骤130之前，AP的WUR接收到第一终端发送的第一唤醒包后，AP将第一唤醒包中的WUR标识信息与自身的WUR的标识信息进行匹配，并根据匹配结果，唤醒AP的主收发模块。
之后，AP根据第一唤醒包中的唤醒指示信息，向第一终端发送第二唤醒包，以用于对第一唤醒包进行响应。
可以理解的是，通过初始化AP的通信规定，即规定AP在接收到唤醒包后，以唤醒包的方式对接收到的唤醒包进行响应，也可以向第一终端发送第二唤醒包，对于该规定的具体操作，本发明实施例不做限定。
步骤440、第一终端根据第二唤醒包，通过第一终端的主收发模块与唤醒后的AP的主收发模块进行数据通信。
第一终端根据接收到的第二唤醒包，确定AP的属性信息，AP的属性信息可以包括 AP的地址信息，AP的小区信息和AP的数据传输方向信息等等，第一终端的主收发模块与确定后的AP的主收发模块进行数据通信。
可选地，第二唤醒包可以包括接收设备的WUR标识信息，如WUR的ID或WUR的接收地址。
第一终端将第一终端的WUR标识信息与接收设备的WUR标识信息进行匹配，当第一终端的WUR标识信息与接收设备的WUR标识信息匹配时，第一终端确定AP的属性信息，并通过第一终端的主收发模块与确定后的AP的主收发模块进行数据通信，进一步使第一终端接收到该第二唤醒包，有效的降低通信过程中的功耗。
当第一终端的WUR标识信息与接收设备的WUR标识信息不匹配时，第一终端认为未收到第二唤醒包(未收到第一唤醒包的确认包)，即第一终端认为AP的主收发模块未被唤醒，此时第一终端可以再次向AP发送第一唤醒包，或继续等待AP发送的第二唤醒包。
可以规定，第一终端当收到第二唤醒包中包含的接收地址为第一终端WUR的接收地址时，即可以认为这是第二唤醒包是对第一唤醒包的唤醒确认。也就是说，通过WUR的ID或WUR的接收地址，隐式地指示该第二唤醒包包含唤醒确认的功能。
进一步的，第二唤醒包也可以通过显式地指示该第二唤醒包包含唤醒确认的功能。在第二唤醒包中配置指示信息字段，该指示信息字段指示第二唤醒包的功能为唤醒确认。如可以用一个特定的唤醒ID或接收地址来指示第二唤醒包的功能为唤醒确认。
可选地，第二唤醒包可以包括AP的发送地址信息，如MAC地址。
第一终端根据AP的发送地址信息，确定AP的属性信息，并通过第一终端的主收发模块与唤醒后的AP进行通信，即显式地，用一种方式使第一终端接收到该第二唤醒包，有效的降低通信过程中的功耗。
可选地，第二唤醒包可以包括数据传输方向信息，如上行(英文：uplink，UL)传输方向或者下行(英文：downlink，DL)传输方向。
第一终端根据数据传输方向信息，确定AP的属性信息，并通过第一终端的主收发模块与唤醒后的AP进行通信，即显式地，用另一种方式使第一终端接收到该第二唤醒包，有效的降低通信过程中的功耗。
可选地，第二唤醒包可以包括AP的小区的标识信息，如小区的基本服务集颜色(英文：Basic service set color，BSS color)。
第一终端根据AP的小区的标识信息，确定AP的属性信息，并通过第一终端的主收发模块与唤醒后的AP进行通信，即显式地，用另一种方式使第一终端接收到该第二唤醒包，有效的降低通信过程中的功耗。
在一个例子中，如图6所示，以AP处于main radio OFF，WUR ON的状态为例，当第一终端有上行数据需要传输时，第一终端向AP发送第一唤醒包，第一唤醒包包含唤醒AP的main radio的指示。此时第一终端的WUR保持工作状态，等待AP回复对第一唤醒包的确认帧。
在AP的WUR收到第一唤醒包后，唤醒AP的main radio。AP发送第二唤醒包，作为第一唤醒包的唤醒确认。第一终端收到第二唤醒包后，确认AP的main radio已醒来。第 一终端给AP的main radio发送数据，从而进行通信。
可以理解的是，上述场景二的通信方法仅仅是一个具体实施方式，并且场景一与场景三也适用于该具体实施方式。
也就是说，对于场景一、场景二与场景三的通信方法还可以有其他的实施方式，本发明实施例对此不做限制。
本发明上述实施例的通信方法中AP在收到第一唤醒包后，通过向第一终端的WUR发送第二唤醒包，降低了第一终端的整体能耗，由于该方法可应用于多场景下。从而提高了AP与终端间无线通信的灵活性。
图7为本发明实施例提供的另一种通信方法的信令交互图。如图6所示，该方法可以包括：
步骤710、第一终端生成第一唤醒包。
当第一终端有数据要发送给AP，即第一终端要进行上行通信时，第一终端生成第一唤醒包，以用于确认AP的主收发模块(如802.11主收发模块)的工作状态为ON状态。
步骤720、第一终端向AP的唤醒接收机WUR发送第一唤醒包，以唤醒AP的主收发模块。
第一唤醒包可以包括AP的WUR标识信息，如WUR的地址信息，以用于指示AP接收该第一唤醒包。该WUR标识信息可以是完整的WUR标识信息或部分的WUR标识信息，如完整的媒体介入控制(英文：Medium Access Control，MAC)地址，或能区分MAC地址的部分地址。
可选地，第一唤醒包还可以包括唤醒指示信息，该唤醒指示信息用于指示AP用唤醒包的方式对第一唤醒包进行响应，该响应可以作为对第一唤醒包的一种唤醒确认，所述“唤醒确认”，可以指确认AP收到了第一唤醒包，或者说确认AP的WUR已经把AP的主收发模块唤醒，即处于ON工作状态。
对于第一唤醒包的结构信息，可以结合步骤420中图5的帧结构进行配置，在此不再赘述。
可以理解的是，根据实际设计需要，唤醒指示信息在载荷域中也可以占用多个比特位，用多个比特值的组合来表示指示AP用唤醒包的方式对第一唤醒包进行响应，本发明实施例在此不做限定。
可选地，唤醒指示信息可以包括第一终端的WUR和/或主收发模块(英文：main radio)的工作状态信息。
若第一终端的WUR OFF，main radio ON，则AP应该用主收发帧(英文：main radio frame)格式回复唤醒确认，若第一终端的WUR ON，main radio OFF，则AP应该用WUR帧格式(唤醒包的方式)回复唤醒确认。
也就是说，AP可以根据第一终端的WUR的工作状态信息，选择用唤醒包的方式对第一唤醒包进行响应，还是用除唤醒包外的其他的方式对第一唤醒包进行响应。
其中，第一终端的WUR的工作状态信息和主收发模块的工作状态信息在载荷域中可以用新建的第一字段来承载；也可以复用第一唤醒包中的其他字段(如预留字段等)来承 载，为表述方便此方式占用的字段也称为第一字段。
可选地，第一字段可以包含1bit，例如，0指示第一终端的WUR ON，main radio OFF；1指示第一终端的WUR OFF，main radio ON。
可替代地，第一字段还可以包含2bit，例如，00指示第一终端的WUR OFF，main radio OFF，01指示WUR OFF，main radio ON，10指示WUR ON，main radio OFF，11指示WUR ON，main radio ON。
可以理解的是，上述第一字段包含的比特位数与具体指示内容的映射仅为举例说明，根据实际需要，第一字段包含的比特位数与具体指示内容还可以有其他形式的映射，本发明实施例在此不做限定。
步骤730、AP根据第一唤醒包广播发送第二唤醒包，以用于对第一唤醒包进行响应，以及向AP关联的至少一个第二终端指示AP的主收发模块已被唤醒。
在执行步骤730之前，AP的WUR接收到第一终端发送的第一唤醒包后，AP将第一唤醒包中的WUR标识信息与自身的WUR的标识信息进行匹配，并根据匹配结果，唤醒AP的主收发模块。
之后，AP根据第一唤醒包中的唤醒指示信息，向第一终端发送第二唤醒包，以用于对第一唤醒包进行响应。
可以理解的是，通过初始化AP，设置AP在接收到第一唤醒包后，以唤醒包的方式对第一唤醒包进行响应。对于该设置的具体操作，本发明实施例不做限定。
步骤740、第一终端和至少一个第二终端根据第二唤醒包，通过第一终端的主收发模块和至少一个第二终端的主收发模块与唤醒后的AP的主收发模块进行数据通信。
第二唤醒包可以包括对第一唤醒包的响应和第一指示信息。
其中，结合上述步骤440中的内容，对第一唤醒包的响应，可以是指根据接收设备的WUR标识信息(如WUR的ID或WUR的接收地址)、AP的发送地址信息(如MAC地址)、数据传输方向信息(如上行或者下行传输方向)或AP的小区的标识信息等信息，确定AP的属性信息，从而对AP接收到第一唤醒包进行确认。第一指示信息，用于向与AP关联的除第一终端以外的至少一个第二终端指示自己的主收发模块已被唤醒，以使AP与AP关联的至少一个第二终端进行通信，从而降低了第二终端的信令开销，有效的缩短了通信时间。
可选地，第二唤醒包还可以包括广播地址。
AP根据广播地址，广播的发送第二唤醒包，使第一终端与至少一个第二终端接收该第二唤醒包。由于第二唤醒包包括对第一唤醒包的响应，故第二唤醒包可以通知至少一个第二终端，自己(AP)的主收发模块已经被唤醒，从而使第一终端与至少一个第二终端分别与AP进行通信。其中，该广播地址可以设置在WUR的ID字段或WUR接收地址字段中。
可选地，在第二唤醒包包含广播地址的基础上，第二唤醒包可以不包含第一终端的WUR标识信息(如WUR的ID或WUR接收地址)，此时，通过设置第一终端只要收到AP发送的第二唤醒包即可认为AP收到了第一唤醒包，即使第二唤醒包中并不包含相应接收终端的WUR的ID(或WUR接收地址)，此时的第二唤醒包是一种隐式的对第一唤醒包的响应。该第二唤醒包的结构可以减少第二唤醒包的长度，有效缩短传输时间。对于上述的设置过 程本发明实施例在此不做限定。
可选地，第二唤醒包还可以包括第一时长。
第一时长为唤醒后的AP的主收发模块的工作时长。也就是说，在第一时长内，AP的主收发模块可以正常通信，不需要被AP的WUR再次唤醒，以使第一终端根据第一时长，与AP的主收发模块进行通信。该第二唤醒包的结构减少了信令开销，缩短了通信时间。
第一终端收到AP发送的第二唤醒包后，已知道AP的主收发模块被唤醒，第一终端识别到第一时长后，与AP在第一时长内进行正常数据通信，若在第一时长结束时，第一终端与AP的通信未结束，第一终端可以再次向AP发送唤醒包，以唤醒AP的主收发模块再次进行数据通信。
需要说明的是，根据实际需要或通信的类别，可以对第一时长的时间段进行预置。
可选地，第二唤醒包还可以包括第二时长。
第二时长为至少一个第二终端不与AP通信的中止时长。也就是说，至少一个第二终端在第二时长之前不与AP进行数据通信，在第二时长之后恢复与AP的数据通信。其中，第二终端是除第一终端以外可以与AP关联的其他终端。该第二唤醒包的结构可以避免至少一个第二终端与第一终端竞争信道，从而可以使第一终端在第二时长内单独与AP进行数据通信，缩短了第一终端与AP的数据通信时间。
需要说明的是，根据实际需要或通信的类别，也可以对第二时长的时间段进行预置。
结合图8所示的结构框图，第二场景可以包括以下两个例子：
在一个例子中，以AP处于main radio OFF，WUR ON的状态为例，当第一终端有上行数据需要传输时，第一终端向AP发送第一唤醒包，第一唤醒包包含唤醒AP的main radio的指示。此时第一终端的WUR保持工作状态，等待AP回复对第一唤醒包的确认帧。
在AP的WUR收到第一唤醒包后，唤醒AP的main radio。AP发送第二唤醒包，该第二唤醒包包括广播地址，向第一终端发送响应，并向与AP关联的第二终端指示AP的main radio已被唤醒。第一终端收到第二唤醒包，以确认AP的main radio已醒来，竞争信道，准备向AP的main radio发送上行数据。关联在该AP下的其他第二终端，收到第二唤醒包，确认AP的main radio已醒来后，其他第二终端也可以竞争信道准备给AP的main radio发送上行数据。
在另一个例子中，以AP处于main radio OFF，WUR ON的工作状态为例，当第一终端有上行数据需要传输时，第一终端向AP发送第一唤醒包，该第一唤醒包包含唤醒AP的main radio的指示。此时第一终端的WUR保持工作状态，等待AP回复对第一唤醒包的确认包。
在AP的WUR收到第一唤醒包后，唤醒AP的main radio。AP发送第二唤醒包，作为对第一唤醒包的确认包，同时告知其他第二终端，AP的main radio已醒来。该第二唤醒包包括第二时长。第一终端收到第二唤醒包后，确认AP的main radio已醒来，准备给AP的main radio发送上行数据。关联在该AP下的其他第二终端，收到第二唤醒包后，确认AP的main radio已醒来，并在第二时长后竞争信道，准备给AP的main radio发送上行数据。
可以理解的是，第二唤醒包中可以包括第一时长或第二时长，也可以包括第一时长 和第二时长。
当第二唤醒包中第一时长和第二时长同时存在时，为了降低信令开销，缩短通信时间，可以设置第一时长的时间段大于第二时长的时间段。
需要说明的是，上述两个例子还适用于场景一与场景三，本发明实施例在此不再赘述。
本发明上述实施例中AP在收到第一唤醒包后，通过向第一终端的WUR发送第二唤醒包，降低了第一终端的整体能耗，并且通过在第二唤醒包中增加广播地址，减少了第二终端向AP发送唤醒包来触发唤醒AP的主收发模块的过程，降低了系统的信令开销，缩短了通信时间，以及在第二唤醒包中通过配置第一时长和/或第二时长，进一步有效控制了通信时间。由于该方法可应用于多场景下，从而提高了AP与终端间无线通信的灵活性。
图9为本发明实施例提供的另一种通信方法的信令交互图。如图9所示，该方法可以包括：
步骤910、第一终端生成第一唤醒包。
当第一终端有数据要发送给AP，即第一终端要进行上行通信时，第一终端生成第一唤醒包，以用于确认AP的主收发模块(如802.11主收发模块)的工作状态为ON状态。
步骤920、第一终端向AP的唤醒接收机WUR发送第一唤醒包，以唤醒AP的主收发模块。
第一唤醒包可以包括AP的WUR标识信息，如WUR的地址信息，以用于指示AP接收该第一唤醒包。该WUR标识信息可以是完整的WUR标识信息或部分的WUR标识信息，如完整的媒体介入控制(英文：Medium Access Control，MAC)地址，或能区分MAC地址的部分地址。
可选地，第一唤醒包还可以包括唤醒指示信息，该唤醒指示信息用于指示AP用唤醒包的方式对第一唤醒包进行响应，该响应可以作为对第一唤醒包的一种唤醒确认，所述“唤醒确认”，可以指确认AP收到了第一唤醒包，或者说确认AP的WUR已经把AP的主收发模块唤醒，即处于ON工作状态。
对于第一唤醒包的结构信息，可以结合步骤420中图5的帧结构进行配置，在此不再赘述。
可以理解的是，根据实际设计需要，唤醒指示信息在载荷域中也可以占用多个比特位，用多个比特值的组合来表示指示AP用唤醒包的方式对第一唤醒包进行响应，本发明实施例在此不做限定。
可选地，唤醒指示信息可以包括第一终端的WUR和/或主收发模块(英文：main radio)的工作状态信息。
若第一终端的WUR OFF，main radio ON，则AP应该用主收发帧(英文：main radio frame)格式回复唤醒确认，若第一终端的WUR ON，main radio OFF，则AP应该用WUR帧格式(唤醒包的方式)回复唤醒确认。也就是说，AP可以根据第一终端的WUR的工作状态信息，选择用唤醒包的方式对第一唤醒包进行响应，还是用除唤醒包外的其他的方式对第一唤醒包进行响应。
其中，第一终端的WUR的工作状态信息和主收发模块的工作状态信息在载荷域中可以用新建的第一字段来承载；也可以复用第一唤醒包中的其他字段(如预留字段等)来承载，为表述方便此方式占用的字段也称为第一字段。
可选地，第一字段可以包含1bit，例如，0指示第一终端的WUR ON，main radio OFF；1指示第一终端的WUR OFF，main radio ON。
可替代地，第一字段还可以包含2bit，例如，00指示第一终端的WUR OFF，main radio OFF，01指示WUR OFF，main radio ON，10指示WUR ON，main radio OFF，11指示WUR ON，main radio ON。
可以理解的是，上述第一字段包含的比特位数与具体指示内容的映射仅为举例说明，根据实际需要，第一字段包含的比特位数与具体指示内容还可以有其他形式的映射，本发明实施例在此不做限定。
步骤930、AP根据第一唤醒包向第一终端和与AP关联的至少一个第三终端发送第二唤醒包，以用于对第一唤醒包进行响应，以及唤醒至少一个第三终端。
在执行步骤930之前，AP的WUR接收到第一终端发送的第一唤醒包后，AP将第一唤醒包中的WUR标识信息与自身的WUR的标识信息进行匹配，并根据匹配结果，唤醒AP的主收发模块。
之后，AP根据第一唤醒包中的唤醒指示信息，向第一终端发送第二唤醒包，以用于对第一唤醒包进行响应。
可以理解的是，通过初始化AP，设置AP在接收到第一唤醒包后，以唤醒包的方式对第一唤醒包进行响应。对于该设置的具体操作，本发明实施例不做限定。
步940、第一终端和唤醒后的至少一个第三终端根据第二唤醒包，通过第一终端的主收发模块和至少一个第三终端的主收发模块与唤醒后的AP的主收发模块进行数据通信。
第二唤醒包可以包括对第一唤醒包的响应和第二指示信息。
结合上述步骤440中的内容，对第一唤醒包的响应，可以是指根据接收设备的WUR标识信息(如WUR的ID或WUR的接收地址)、AP的发送地址信息(如MAC地址)、数据传输方向信息(如上行或者下行传输方向)或AP的小区的标识信息等信息，确定AP的属性信息，从而对AP接收到第一唤醒包进行确认。
第二指示信息，用于唤醒AP关联的至少一个第三终端，以使第一终端和至少一个第三终端，分别与AP进行数据通信，从而降低了第三终端的信令开销，有效的缩短了通信时间。
可选地，第二唤醒包还可以包括至少一个第三终端的WUR标识信息，如WUR的ID或WUR接收地址，以使至少一个第三终端接收第二唤醒包，以唤醒至少一个第三终端的主收发模块。
由于第二唤醒包包括对第一唤醒包的响应，故第二唤醒包可以通知至少一个第三终端，自己(AP)的主收发模块已经被唤醒，从而使第一终端的主收发模块与至少一个第三终端的主收发模块分别与唤醒后的AP的主收发模块进行通信。
可选地，第二唤醒包还可以不包含第一终端的WUR标识信息(如WUR的ID或WUR接 收地址)，此时，通过设置第一终端只要收到AP发送的第二唤醒包即可认为AP收到了第一唤醒包，即使第二唤醒包中并不包含相应接收终端的WUR的ID(或WUR接收地址)，此时的第二唤醒包是一种隐式的对第一唤醒包的响应。该第二唤醒包的结构可以减少第二唤醒包的长度，有效缩短传输时间。对于上述的设置过程本发明实施例在此不做限定。
结合图10所示的结构框图，第二场景可以包括以下两个例子：
在一个例子中，以AP处于main radio OFF，WUR ON的状态为例，，当第一终端有上行数据需要传输时，第一终端给AP发送第一唤醒包，第一唤醒包包含唤醒AP的main radio的指示。此时第一终端的WUR保持工作状态，等待AP回复对第一唤醒包的确认帧。
在AP的WUR收到第一唤醒包后，唤醒AP的main radio。AP发送第二唤醒包，该第二唤醒包包括广播地址，向第一终端发送响应，该第二唤醒包还包含第二指示信息，以用于唤醒与AP关联的一个或多个第三终端。
第一终端收到第二唤醒包，确认AP的main radio已醒来。准备给AP的main radio发送上行数据。一个或多个第三终端收到第二唤醒包后，唤醒各自的main radio，准备接收来自AP的下行数据。AP接收完第一终端的数据之后，AP向一个或多个第三终端的main radio发送下行数据。
值得注意的是，上述例子也可以应用于场景一和场景三，本发明实施例在此不再赘述。
本发明上述实施例中AP在收到第一唤醒包后，通过向第一终端的WUR发送第二唤醒包，降低了第一终端的整体能耗，并且通过在第二唤醒包中配置至少一个第三终端的WUR标识信息，唤醒相应第三终端的主收发模块，降低了系统的信令开销，缩短了通信时间。由于该方法可应用于多场景下，从而提高了AP与终端间无线通信的灵活性。
