Definitions
- This document relates to the field of message transmission technologies, such as a method for transmitting and receiving wake-up messages, and a transmitting and receiving device.
- the wake-up receiver (WUR) is designed to further reduce the energy consumption of the wireless device in standby mode and improve the service life of the wireless device.
- the WUR-integrated WLAN wireless device can turn off the main power module (here, the WLAN module) with high power consumption, and enable the low-power WUR module. If the WUR module receives the wakeup message within the next time, the wireless device that triggered the trigger turns on the WLAN module again to complete the necessary information interaction.
- the introduction of the WUR module into the wireless device greatly alleviates the system delay caused by the failure to respond to the burst message in time due to the complete shutdown of the main module.
- the bearer of the wake-up message received by the WUR is a wake-up radio frame.
- the wake-up radio frame is composed of a traditional WLAN preamble, a wake-up frame preamble sequence, and a wake-up frame payload.
- the modulation method used for waking up the wake-up part of the radio frame is Orthogonal Frequency Division Multiplexing (OFDM) + Binary On/Off Keying OOK, that is, the 'On' state of OOK.
- OFDM Orthogonal Frequency Division Multiplexing
- OOK Binary On/Off Keying
- the information bit '1' or '0' may be represented by one or more 'On' and/or 'Off' states, for example, the 'On' state indicates '1' and the 'Off' state indicates '0'; or, continuous 'On' and 'Off' indicate '1', and consecutive 'Off' and 'On' indicate '0' (ie, Manchester coding is applied). Therefore, after receiving the wake-up message of the corresponding rate, the WUR may demodulate the wake-up message according to the rate of the wake-up message.
- rate multiple access technology can be applied to the transmission of the wake-up message.
- the so-called rate multiple access is to superimpose the wake-up messages of different rates in the time domain and send them to one or more WURs. Therefore, after receiving the wake-up message transmitted using the rate multiple access technique, the rate of the wake-up message needs to be identified.

Abstract
本文公布了一种唤醒信息的发送和接收方法及装置,其中,所述发送方法包括:将唤醒消息承载在唤醒无线帧的唤醒帧负载中向唤醒接收器发送;所述唤醒无线帧携带唤醒帧负载承载的一种或多种速率唤醒消息的速率指示信息。本文可实现清楚地指示唤醒消息的承载速率。
Description
本文涉及消息传输技术领域,例如一种唤醒消息的发送、接收方法以及发送、接收装置。
唤醒接收器(wake-up receiver,WUR)旨在进一步降低无线设备在待机状态下的能量消耗,提高无线设备电源的使用寿命。
当无线设备在待机状态下,为降低能量消耗,集成WUR的WLAN无线设备可以将功耗偏大的主模块(这里指的是WLAN模块)关闭,同时使能低功耗的WUR模块。如果WUR模块在接下来的时间内接收到唤醒消息,则触发所在的无线设备再次开启WLAN模块,完成必要的信息交互。将WUR模块引入无线设备,在实现节电的同时也极大的缓解了因完全关闭主模块而无法及时响应突发消息而带来的系统时延问题。
WUR接收到的唤醒消息的载体为唤醒无线帧。唤醒无线帧由传统WLAN前导、唤醒帧前导序列、唤醒帧负载共同组成。不同于传统WLAN系统,唤醒无线帧的唤醒部分(包括唤醒帧前导序列、唤醒帧负载)使用的调制方式为正交频分复用OFDM+二进制启闭键控OOK,即在OOK的‘On’状态下发送OFDM符号,在‘Off’状态下不发送任何信息。信息比特‘1’或‘0’可由一个或多个‘On’和/或‘Off’状态表示,例如,‘On’状态表示‘1’,‘Off’状态表示‘0’;或,连续的‘On’和‘Off’表示‘1’,连续的‘Off’和‘On’表示‘0’(即应用Manchester编码)。因此,WUR在接收到相应速率的唤醒消息后,可根据所述唤醒消息的速率对唤醒消息进行解调。
为了提高唤醒信号的传输效率,速率多址技术可以被应用到唤醒消息的传输。所谓速率多址就是将不同速率的唤醒消息在时域叠加在一起,向一个或多个WUR发送。因此,在接收到使用速率多址技术传输的唤醒消息后,需要识别所述唤醒消息的速率。
