In the application.
技术领域Technical field
本申请涉及通信领域,并且更具体地,涉及无线通信的方法和设备。The present application relates to the field of communications and, more particularly, to a method and apparatus for wireless communication.
背景技术Background technique
随着无线局域网(Wireless Local Area Network,WLAN)标准的演进,在无线保真(Wireless Fidelity,Wi-Fi)网络中,终端在没有消息收发时,会有很大一部分能量浪费在侦听信道中的无线信号中,终端采用低功耗的唤醒接收器(Low Power Wake Up Radio,LP-WUR)(以下简称WUR)代替无线收发器在媒介空闲时侦听信道,因此终端除了无线收发器,还装备WUR。当终端的无线收发器进入深度休眠后,终端的低功耗的WUR可以苏醒开始工作。当AP需要与装备有WUR和无线收发器的终端通信时,AP向终端的WUR发送WUR消息,如唤醒帧(Wake Up Packet,WUP),终端的WUR正确收到发给自己的WUP后唤醒终端的无线收发器,然后终端的WUR可以转入休眠,AP则与终端的苏醒的无线收发器进行通信。终端的无线收发器与AP通信完成后会进入休眠,同时终端的WUR苏醒又开始侦听是否有发送给自己的WUP,以便再次唤醒终端的无线收发器。With the evolution of the Wireless Local Area Network (WLAN) standard, in a Wireless Fidelity (Wi-Fi) network, when a terminal does not receive or send a message, a large part of the energy is wasted in the listening channel. In the wireless signal, the terminal uses Low Power Wake Up Radio (LP-WUR) (hereinafter referred to as WUR) instead of the wireless transceiver to listen to the channel when the medium is idle, so the terminal in addition to the wireless transceiver, Equipped with WUR. When the wireless transceiver of the terminal enters deep sleep, the low-power WUR of the terminal can wake up and start working. When the AP needs to communicate with the terminal equipped with the WUR and the wireless transceiver, the AP sends a WUR message to the WUR of the terminal, such as a Wake Up Packet (WUP), and the WUR of the terminal correctly receives the WUP sent to itself and wakes up the terminal. The wireless transceiver, then the terminal's WUR can go to sleep, and the AP communicates with the terminal's awake wireless transceiver. After the terminal's wireless transceiver communicates with the AP, it will go to sleep. At the same time, the terminal's WUR wakes up and starts to listen to whether there is a WUP sent to itself, so as to wake up the terminal's wireless transceiver again.
为了进一步降低能耗,WUR引入了休眠机制,休眠机制是指WUR周期性的开启(醒来)或关闭。当WUR采用休眠机制时,只有在WUR开启时才能接收到接入点发送的WUP。如果接入点需要在短时间内需要唤醒多个终端,即需要短时间内发送多个WUP,同时多个终端的WUR开启时间较短,则接入点可能无法在一个WUR开启时间(WUR的一个醒来窗口)内发送完多个WUP,接入点需要等到下一个WUR开启时间才能继续发送未发送完的WUP,导致唤醒多个终端需要耗费较长时间;或者接入点在短时间内唤醒多个终端时需要发送的大量的WUR信息,会过多占用了无线信道的资源。To further reduce power consumption, WUR introduces a sleep mechanism, which means that the WUR is periodically turned on (wake up) or turned off. When the WUR adopts the sleep mechanism, the WUP sent by the access point can be received only when the WUR is enabled. If the access point needs to wake up multiple terminals in a short period of time, that is, it needs to send multiple WUPs in a short time, and the WUR opening time of multiple terminals is short, the access point may not be able to be in a WUR open time (WUR After a plurality of WUPs are sent in a wake-up window, the access point needs to wait until the next WUR open time to continue sending the unsent WUP, which causes a long time to wake up multiple terminals; or the access point is in a short time A large amount of WUR information that needs to be sent when waking up multiple terminals will occupy too much resources of the wireless channel.
因此,如何使得接入点在短时间内发送多个唤醒帧,并且减小对无线信道资源的占用是一项亟待解决的问题。Therefore, how to enable an access point to send multiple wake-up frames in a short time and reduce the occupation of wireless channel resources is an urgent problem to be solved.

As shown in FIG. 1, the communication system 100 includes a network device 102, which may include multiple antennas, such as antennas 104, 106, 108, 110, 112, and 114. Additionally, network device 102 may additionally include a transmitter chain and a receiver chain, as will be understood by those of ordinary skill in the art, which may include multiple components related to signal transmission and reception (eg, processor, modulator, multiplexer) , demodulator, demultiplexer or antenna, etc.).
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而,可以理解,网络设备102可以与类似于终端设备116或122的任意数目标终端设备通信。 Network device 102 can communicate with a plurality of terminal devices, such as terminal device 116 and terminal device 122. However, it will be appreciated that network device 102 can communicate with any number of target terminal devices similar to terminal device 116 or 122.
如图1所示,终端设备116与天线112和114通信,其中天线112和114通过前向链路118向终端设备116发送信息,并通过反向链路120从终端设备116接收信息。此外,终端设备122与天线104和106通信,其中天线104和106通过前向链路124向终端设备122发送信息,并通过反向链路126从终端设备122接收信息。As shown in FIG. 1, terminal device 116 is in communication with antennas 112 and 114, wherein antennas 112 and 114 transmit information to terminal device 116 over forward link 118 and receive information from terminal device 116 over reverse link 120. In addition, terminal device 122 is in communication with antennas 104 and 106, wherein antennas 104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126.

再例如,在时分双工(Time Division Duplex,TDD)系统和全双工(Full Duplex,FD)系统中,前向链路118和反向链路120可使用共同频带,前向链路124和反向链路126可使用共同频带。As another example, in a Time Division Duplex (TDD) system and a Full Duplex (FD) system, the forward link 118 and the reverse link 120 can use a common frequency band, the forward link 124 and Reverse link 126 can use a common frequency band.

For example, the antenna group can be designed to communicate with terminal devices in sectors of the network device 102 coverage area. In the process in which network device 102 communicates with terminal devices 116 and 122 via forward links 118 and 124, respectively, the transmit antenna of network device 102 may utilize beamforming to improve the signal to noise ratio of forward links 118 and 124. In addition, when the network device 102 uses beamforming to transmit signals to the randomly dispersed terminal devices 116 and 122 in the relevant coverage area, the network device 102 uses a single antenna to transmit signals to all of its terminal devices. Mobile devices are subject to less interference.
在给定时间,网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时,无线通信发送装置可对数据进行编码以用于传输。具体地,无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目标数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中,传输块可被分段以产生多个码块。At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting device and/or a wireless communication receiving device. When transmitting data, the wireless communication transmitting device can encode the data for transmission. In particular, the wireless communication transmitting device may acquire (eg, generate, receive from other communication devices, or store in memory, etc.) a certain number of target data bits to be transmitted to the wireless communication receiving device over the channel.

具体而言,该异步工作模式为该多个第二设备的第一接口和该第一设备的时钟不需要保持同步,即该第一设备仅知道该第二设备的WUR会周期性的苏醒或关闭,但是该第一设备并不能获知该第二设备的WUR在哪个时刻苏醒或关闭。该第一设备为了确保该第二设备在一个休眠机制内收到该第一消息,因此,该第一设备在该第一时段内连续向该多个第二设备的接口发送多个该第一消息,其中,两个相邻的该第一消息的间隔小于或等于该每个第一设备在第一时段内连续向该多个第二设备的第一接口发送多个该第一消息,该第一时段的时长大于或等于每个第二设备中任一个第二设备的该休眠机制中一个该休眠周期的时长。Specifically, the asynchronous working mode is that the first interface of the multiple second devices and the clock of the first device do not need to be synchronized, that is, the first device only knows that the WUR of the second device periodically wakes up or Closed, but the first device does not know at which point the WUR of the second device wakes up or shuts down. The first device, in order to ensure that the second device receives the first message in a dormant mechanism, the first device continuously sends the first message to the interfaces of the multiple second devices in the first time period. a message, wherein the interval between two adjacent first messages is less than or equal to that the first device continuously sends a plurality of the first messages to the first interface of the multiple second devices in the first time period, where The duration of the first period of time is greater than or equal to the duration of one of the sleep periods of the one of the second devices of each of the second devices.
应理解,该第一设备在第一时段内连续向该多个第二设备的第一接口发送多个该第一消息是指该第一设备在该第一时间段内以小于或等于该每个第二设备中任一个第二设备在一个休眠周期内该第一接口的一个连续开启时段为频率向该第二设备的第一接口发送多个该第一消息。It should be understood that the sending, by the first device, the plurality of the first message to the first interface of the multiple second devices in the first time period means that the first device is less than or equal to the first time in the first time period. The second device of the second device sends a plurality of the first messages to the first interface of the second device for a continuous open period of the first interface in a sleep period.
还应理解,如果第二设备的第一接口接收到所述第一消息,同时其休眠机制已处于关闭状态,则第二设备的第一接口继续维持休眠机制的关闭。It should also be understood that if the first interface of the second device receives the first message while its sleep mechanism is already in the off state, the first interface of the second device continues to maintain the shutdown of the sleep mechanism.
例如,第二设备1的休眠机制的长度为100ms,其中苏醒窗口的长度为30ms,该苏醒窗口在该休眠机制中连续,不存在间隔,休眠窗口的长度为70ms;第二设备2的休眠机制的长度为100ms,其中苏醒窗口的长度为20ms,该苏醒窗口在该休眠机制中连续,不存在间隔,休眠窗口的长度为80ms;第二设备3的休眠机制的长度为110ms,其中苏醒窗口的长度为40ms,该苏醒窗口在该休眠机制中连续,不存在间隔,休眠窗口的长度为70ms,当该第一设备向该第二设备1、第二设备2和第二设备3发送第一消息时,该 For example, the length of the sleep mechanism of the second device 1 is 100 ms, wherein the length of the wake window is 30 ms, the wake window is continuous in the sleep mechanism, there is no interval, the length of the sleep window is 70 ms; the sleep mechanism of the second device 2 The length of the wakeup window is 20ms, wherein the wakeup window is continuous in the sleep mechanism, there is no interval, the length of the sleep window is 80ms; the length of the sleep mechanism of the second device 3 is 110ms, wherein the wakeup window is The length is 40 ms, the awake window is continuous in the sleep mechanism, there is no interval, and the length of the sleep window is 70 ms. When the first device sends the first message to the second device 1, the second device 2, and the second device 3 When,
第一设备发送该第一消息的间隔小于或等于20ms,并且该第一设备发送该第一消息的时间段大于或等于110ms。The interval at which the first device sends the first message is less than or equal to 20 ms, and the time period during which the first device sends the first message is greater than or equal to 110 ms.
又例如,如果第二设备1的休眠机制的苏醒窗口的长度为30ms,但是该苏醒窗口又分为第一苏醒窗口和第二苏醒窗口,该第一苏醒窗口和该第二苏醒窗口分别为20ms和10ms,如图4所示,该第一苏醒窗口和该第二苏醒窗口被休眠窗口间隔开。当该第一设备向该第二设备1、第二设备2和第二设备3发送第一消息时,该第一设备发送该第一消息的间隔小于或等于20ms,并且该第一设备发送该第一消息的时间段大于或等于110ms。For another example, if the length of the wake-up window of the sleep mechanism of the second device 1 is 30 ms, the wake-up window is further divided into a first wake-up window and a second wake-up window, and the first wake-up window and the second wake-up window are respectively 20 ms. And 10 ms, as shown in FIG. 4, the first wake-up window and the second wake-up window are spaced apart by the sleep window.

And 15ms. When the first device sends the first message to the second device 1, the second device 2, and the second device 3, the interval at which the first device sends the first message is less than or equal to 15 ms, and the first device sends the The time period of the first message is greater than or equal to 110 ms.
可选地,该第一设备与该多个第二设备为同步工作模式,该同步工作模式为该多个第二设备的第一接口和该第一设备的时钟保持同步,该第一设备以广播或多播的方式向多个第二设备中的每个第二设备的第一接口发送第一消息,包括:在该多个第二设备的第一接口的开启时段,以广播或多播的方式向该多个第二设备发送该第一消息。Optionally, the first device and the plurality of second devices are in a synchronous working mode, where the first interface of the plurality of second devices is synchronized with a clock of the first device, where the first device is Transmitting or multicasting the first message to the first interface of each of the plurality of second devices, including: broadcasting or multicasting during an on period of the first interface of the plurality of second devices The manner of transmitting the first message to the plurality of second devices.
具体而言,该同步工作模式为该多个第二设备的第一接口和该第一设备的时钟保持同步,该第一设备需要发送消息以维持与终端WUR的同步(如WUR beacon),即该第一设备不仅知道该第二设备的WUR会周期性的苏醒或关闭,而且该第一设备并可以准确获知该第二设备的WUR在哪个时刻苏醒或关闭。该第一设备可以在相应的第二设备的WUR的苏醒窗口内向该第二设备发送该第一消息。Specifically, the synchronous working mode is that the first interface of the multiple second devices is synchronized with the clock of the first device, and the first device needs to send a message to maintain synchronization with the terminal WUR (such as a WUR beacon), that is, The first device not only knows that the WUR of the second device is periodically awake or closed, but also the first device can accurately know at which time the WUR of the second device wakes up or shuts down. The first device may send the first message to the second device within the wakeup window of the WUR of the corresponding second device.
例如,在图5中,该第一设备向该第二设备1、该第二设备2和该第二设备3在其苏醒窗口内分别发送以广播或多播的方式发送该第一消息。For example, in FIG. 5, the first device sends the first message to the second device 1, the second device 2, and the second device 3 in a wake-up window thereof to broadcast or multicast.
可选地,该第一设备在该多个第二设备的第一接口的开启时段,以广播或多播的方式向该多个第二设备发送该第一消息,包括:当该多个第二设备中的部分第二设备的第一接口的开启时段重叠时,在该多个第二设备中的部分第二设备的第一接口的开启时段的重叠时段,以广播或多播的方式向该部分第二设备发送该第一消息。Optionally, the first device sends the first message to the multiple second devices in a broadcast or multicast manner during the opening period of the first interface of the multiple second devices, including: when the multiple When the opening periods of the first interfaces of the second devices in the two devices overlap, the overlapping periods of the opening periods of the first interfaces of the second devices in the plurality of second devices are broadcasted or multicasted to each other. The part of the second device sends the first message.
具体而言,如果该多个第二设备的苏醒窗口的开启时间段重合,该第一设备可以在该多个第二设备的苏醒窗口的重叠时段,向该多个第二设备以广播或多播的方式向该第二设备发送该第一消息,如图6所示,该第二设备1、该第二设备2和该第三设备3的苏醒窗口对齐(或有共同重叠的区域),该第一设备可以仅发送一个第一消息。Specifically, if the opening time periods of the waking windows of the plurality of second devices coincide, the first device may broadcast or multicast the plurality of second devices during an overlapping period of the waking windows of the plurality of second devices. The first message is sent to the second device, as shown in FIG. 6, the second device 1, the second device 2, and the third device 3 are aligned (or have overlapping areas), The first device may only send one first message.
可选地,该第一消息至少可以携带该第一设备所处基本服务集(Basic Service Set,BSS)的广播标识或多播标识,如第一设备所处BSS的广播WUR标识,所有与第一设备关联的第二设备的第一接口可以识别该WUR标识;或,多播标识,如多播WUR标识,与第一设备关联的部分第二设备的第一接口可识别;第一消息至少可以携带完整或截短的第一设备的第一接口的标识,如第一设备的WUR标识,或BSS color(用以粗略的区分无线保真(WirelessFidelity,Wi-Fi)网络,可以作为接入点的截短标识)。Optionally, the first message may at least carry a broadcast identifier or a multicast identifier of a basic service set (BSS) where the first device is located, such as a broadcast WUR identifier of the BSS where the first device is located, and all The first interface of the second device associated with the device may identify the WUR identifier; or the multicast identifier, such as the multicast WUR identifier, may be identified by the first interface of the second device associated with the first device; the first message is at least The identifier of the first interface of the first device that can be carried in full or truncated, such as the WUR identifier of the first device, or the BSS color (for roughly distinguishing the wireless Fidelity (Wi-Fi) network, which can be used as an access The truncated mark of the point).
可选地,可以使用截短的广播标识,或截短的发送标识,用于一个或多个第二设备的第一接口识别该第一消息。第一消息尽可能的保持简短可以减少因连续发送多个第一消息而占用过多的无线信道资源。 Alternatively, the truncated broadcast identifier or the truncated transmission identifier may be used, and the first interface for the one or more second devices identifies the first message. Keeping the first message as short as possible can reduce the excessive radio channel resources occupied by continuously transmitting a plurality of first messages.
可选地,该第一消息为WUR消息。如图7所示,WUR消息的帧结构可分为先导和载荷,其中先导带宽大于载荷带宽。所述先导为802.11先导,即传统802.11设备可以听懂的先导序列,在20MHz或20MHz整数倍(如40MHz,80MHz,或160MHz)的带宽上发送,使得传统802.11设备可以据此判定当前消息(实际为WUR消息)为Wi-Fi消息,用于兼容传统802.11设备。听到该802.11先导的传统802.11设备能够根据802.11先导中的信息(如Length域信息)获得WUR消息占用信道的时间,在这段时间内不尝试接入信道进而避免干扰传输中的WUR消息。所述长度域信息为12bits,指示所述消息数据部分需要传输的字节数量,在图7中,先导部分仅示出了长度域,应理解该长度域属于先导的子集,先导还包含其他子域。Optionally, the first message is a WUR message. As shown in FIG. 7, the frame structure of the WUR message can be divided into a preamble and a payload, wherein the pilot bandwidth is greater than the payload bandwidth. The preamble is an 802.11 preamble, that is, a pilot sequence that can be understood by a conventional 802.11 device, and is transmitted over a bandwidth of 20 MHz or 20 MHz integer multiples (such as 40 MHz, 80 MHz, or 160 MHz), so that the conventional 802.11 device can determine the current message according to the actual (actually For WUR messages) is a Wi-Fi message for compatibility with legacy 802.11 devices. The traditional 802.11 device that hears the 802.11 pilot can obtain the time when the WUR message occupies the channel according to the information in the 802.11 preamble (such as the Length domain information), and does not attempt to access the channel during this time to avoid interfering with the WUR message in the transmission. The length field information is 12 bits, indicating the number of bytes that need to be transmitted in the message data part. In FIG. 7, the pilot part only shows the length field, and it should be understood that the length field belongs to a subset of the pilot, and the pilot also includes other Subdomains.
换句话说,根据Length域指示的信息和802.11先导的传输速率,可以计算出传输所述消息所需的剩余时间。所述载荷为WUR消息的Payload部分,采用解调复杂度低的调制方式,如OOK调制,即二进制幅度调制(Binary Amplitude Shift Keying,2BASK),并使用窄带传输,如1MHz信道、2MHz信道、5MHz信道等(传统802.11最小信道带宽为20MHz),这使得接收端进一步降低能耗。WUR消息的Payload包括Wake-Up Preamble和媒介接入控制(medium Access Control,MAC)部分,其中前者的作用与传统802.11先导类似,可用于WUR识别WUR信号;后者与Wi-Fi消息的MAC部分相似,进一步可以包括MAC Header,Frame Body和帧校验序列(Frame Check Sequence,FCS)。这里MAC Header至少携带第二设备的标识;Frame Body可承载一些指示、控制信息等;FCS属于校验信息,用于判断该消息是否接收出错。In other words, based on the information indicated by the Length field and the transmission rate of the 802.11 pilot, the remaining time required to transmit the message can be calculated. The payload is a Payload portion of the WUR message, and uses a modulation method with low demodulation complexity, such as OOK modulation, ie Binary Amplitude Shift Keying (2BASK), and uses narrowband transmission, such as 1 MHz channel, 2 MHz channel, 5 MHz. Channels, etc. (traditional 802.11 minimum channel bandwidth is 20MHz), which allows the receiver to further reduce power consumption. The Payload of the WUR message includes the Wake-Up Preamble and the Medium Access Control (MAC) part, wherein the former functions similarly to the traditional 802.11 pilot and can be used for WUR to identify the WUR signal; the latter and the MAC portion of the Wi-Fi message. Similarly, it may further include a MAC Header, a Frame Body, and a Frame Check Sequence (FCS). Here, the MAC Header carries at least the identifier of the second device; the Frame Body can carry some indications, control information, and the like; the FCS belongs to the verification information, and is used to determine whether the message receives an error.
可选地,本申请给出了一种可能的第一消息第一载荷部分的帧结构,如图8所示。该第一消息的第一载荷至少可以包括类型Type域、接收地址域(Receive Address,RA)和帧校验(Frame Check Sequence,FCS);可选地,还可以包括发送地址域(Transmit Address,TA)。该Type域为WUR消息的帧控制域,用于指示该帧类型及功能,该第一消息的帧类型可以在Type域使用1比特指示位指示。当该比特位为1时表明该第一消息为DC off消息,用于关闭该第二设备的第一接口的休眠机制。该RA域为第一消息的接收地址,以帮助第二设备的第一接口识别第一消息是发给自己的。该FCS为帧校验,用于第二设备的第一接口确定正确接收到了第一消息。该TA域为第一消息的发送地址,该发送地址可以使用完整或截短的第一设备的第一接口标识,如BSS color(截短的标识),以粗略的区分不同Wi-Fi网络。使用BSS color的好处是占用比特指示位较使用完整的发送地址较少,缺点是有可能跟邻近的Wi-Fi网络使用重复的BSS color。Optionally, the present application provides a frame structure of a first payload portion of a possible first message, as shown in FIG. The first payload of the first message may include at least a Type Domain, a Receive Address (RA), and a Frame Check Sequence (FCS); optionally, a Transmit Address, TA). The Type field is a frame control field of the WUR message, and is used to indicate the frame type and function. The frame type of the first message may be indicated by using a 1-bit indicator bit in the Type field. When the bit is 1, it indicates that the first message is a DC off message, and is used to disable the sleep mechanism of the first interface of the second device. The RA field is a receiving address of the first message to help the first interface of the second device identify that the first message is sent to itself. The FCS is frame check, and the first interface for the second device determines that the first message is correctly received. The TA field is a sending address of the first message, and the sending address may use a first interface identifier of the first device that is completely or truncated, such as a BSS color (truncated identifier), to roughly distinguish different Wi-Fi networks. The advantage of using BSS color is that the occupied bit indication bit is less than the full transmit address. The disadvantage is that it is possible to use a duplicate BSS color with a neighboring Wi-Fi network.
S220,第二设备通过第一接口接收第一设备发送的第一消息,该第一消息用于指示该第二设备关闭该第一接口的休眠机制。S220. The second device receives, by using the first interface, a first message sent by the first device, where the first message is used to instruct the second device to disable the dormancy mechanism of the first interface.
S230,该第二设备根据该第一消息,关闭该第一接口的休眠机制。S230. The second device turns off the sleep mechanism of the first interface according to the first message.
该第二设备的WUR接收到该第一消息后,关闭该第一接口的休眠机制,即该第一接口一直开启,用于接收第二消息。After receiving the first message, the WUR of the second device turns off the sleep mechanism of the first interface, that is, the first interface is always on, and is used to receive the second message.
S240,该第一设备向该多个第二设备中的至少一个第二设备(至少一个可以为一个或多个,当需要唤醒多个第二设备时,可以为至少两个)的第一接口发送第二消息,该 第二消息用于指示该至少一个第二设备开启该至少一个第二设备的第二接口,以便该第一设备通过该至少一个第二设备的该第二接口与该至少一个第二设备通信。S240. The first device sends a first interface to at least one of the plurality of second devices (at least one of which may be one or more, when at least two devices need to be awake, at least two) Send a second message, the The second message is used to instruct the at least one second device to enable the second interface of the at least one second device, so that the first device communicates with the at least one second device by using the second interface of the at least one second device.
可选地,该第二消息为低功耗唤醒接收器的唤醒帧(Wake Up Packet,WUP)。Optionally, the second message is a wake-up frame (WUP Up Packet, WUP) of the low-power wake-up receiver.
可选地,该第二接口用于接收无线收发器的消息Optionally, the second interface is configured to receive a message of the wireless transceiver
由于与第一设备关联的第二设备的第一接口均已保持开启,因此可以确保第一设备在发送第二消息时所述一个或多个第二设备的第一接口处于苏醒状态。Since the first interface of the second device associated with the first device has been kept open, it can be ensured that the first interface of the one or more second devices is in the awake state when the first device sends the second message.
