本申请实施例涉及通信技术领域,尤其涉及一种唤醒方法和装置。Embodiments of the present application relate to the field of communication technologies, and in particular, to a wakeup method and device.
在无线保真(Wireless Fidelity,WiFi)网络中,设备相当一部分能量浪费在无接收信号时的监听(idle listening),为了减少设备监听时能量浪费,现有技术使用低功耗唤醒无线电(Low Power Wake Up Radio,LP-WUR)技术减少设备idle listening能量浪费。In a wireless fidelity (WiFi) network, a considerable part of the device ’s energy is wasted during idle listening when no signal is being received. In order to reduce energy wasted while the device is listening, existing technologies use low power wake-up radios (Low Power Wake Up Radio (LP-WUR) technology reduces equipment idle listening energy waste.
LP-WUR的核心思想是接收端设备(如站点STA)除包含主收发模块(primary connectivity radio,PCR)外,还包括唤醒无线电(Wake Up Radio,WUR)部分。如图1所示,当PCR处于关闭状态时,WUR苏醒开始工作,当其他设备(如图1中的接入点AP)需要与带有WUR和PCR的设备(如图1中的站点STA)通信时,接入点(Access Point,AP)向站点(Station,STA)的WUR发送唤醒帧,WUR正确接收到唤醒帧之后,PCR将被唤醒,进行无线帧的正常收发,WUR自己可以转入休眠或关闭状态。The core idea of LP-WUR is that the receiving end equipment (such as the station STA) includes a Wake Up Radio (WUR) part in addition to the primary transceiver module (PCR). As shown in Figure 1, when the PCR is turned off, WUR wakes up and starts to work. When other devices (such as the access point AP in Figure 1) need to communicate with devices with WUR and PCR (such as the station STA in Figure 1) During communication, the access point (Access Point, AP) sends a wake-up frame to the WUR of the station (Station, STA). After the WUR receives the wake-up frame correctly, the PCR will be awakened to perform normal transmission and reception of wireless frames, and the WUR can transfer itself. Hibernate or shut down.
当STA的WUR收到AP发送的唤醒帧后,有两种可能的唤醒模式:模式一、STA的WUR接收唤醒帧后唤醒其PCR,PCR通过信道竞争,竞争成功后向AP发送响应帧,以便通知AP该PCR进入苏醒状态;模式二、AP向STA的WUR发送唤醒帧,等待一定时延后向STA的PCR发送触发帧或数据帧,PCR在接收到AP发送的触发帧或数据帧之后,向AP发送响应帧,以便通知AP该PCR进入苏醒状态。When the WUR of the STA receives the wake-up frame sent by the AP, there are two possible wake-up modes: Mode 1. After the WUR of the STA receives the wake-up frame, it wakes up its PCR. PCR passes the channel competition. After the competition is successful, it sends a response frame to the AP in order to Notify the AP that the PCR has entered the awake state; Mode 2. The AP sends a wake-up frame to the WUR of the STA, and waits for a certain delay to send a trigger frame or data frame to the STA's PCR. After the PCR receives the trigger frame or data frame sent by the AP, Send a response frame to the AP to notify the AP that the PCR enters the awake state.
现有技术中,AP可以配置STA采用唤醒模式一或唤醒模式二通知AP该主收发模块进入苏醒状态,但是现有技术中的唤醒方法不能有效的管理多种唤醒模式,存在网络资源利用率低,能量消耗较大的问题。In the prior art, the AP can configure the STA to use the wake-up mode 1 or the wake-up mode 2 to notify the AP that the main transceiver module has entered the awake state, but the wake-up method in the prior art cannot effectively manage multiple wake-up modes, and low network resource utilization exists. The problem of large energy consumption.
