Communication method and communication device of wireless local area network, and communication equipment

Abstract

The invention provides a communication method and a communication device of a wireless local area network, and communication equipment. The communication method of the wireless local area network comprises the steps of generating a waking frame that is used for waking a data frame receiver of the equipment to enter a waking state to receive data frames; determining spectrum resources sending the waking frame, wherein the spectrum resources used for sending the waking frame are not overlapped with the spectrum resources occupied by a main communication channel, and the bandwidth of the spectrumresources used for sending the waking frame is less than that of the main communication channel; and sending the waking frame based on the determined spectrum resources. According to the technical scheme of the method provided by the invention, the sending of the waking frame does not cause interference on the main communication channel, and thus the occurrence of communication conflicts can be avoided, the improvement of the spectrum efficiency is facilitated, and the requirement of the WUR is met.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a communication method of a wireless local area network, a communication device of a wireless local area network and a communication device. Background technique [0002] In July 2016, 802.11 established the next-generation Wi-Fi (Wireless Fidelity, Wireless Fidelity) technology research group WUR (Wake Up Receiver), which is mainly used in the Internet of Things, with the purpose of saving equipment power as much as possible. consumption. [0003] A wake up frame is defined in the WUR research group, in which the data frame receiver of the device can be in a dormant state, and when the wake up frame receiver of the device receives the wake up frame, it will wake up the data frame receiver It can be seen that the purpose of defining the Wake up frame is to help the device save power consumption. [0004] However, in existing Wi-Fi application scenarios, there is ...

AI Technical Summary

Problems solved by technology

[0004] However, in existing Wi-Fi application scenarios, there is a large amount of management information, such as beacon frames. If the wake up frame is still in the same channel as the beacon frame or in the spectrum resource occupied by the transmission channel of the beacon Transmission in overlapping channels will make the originally busy channel more congested, which may cause information conflicts and lead to waste of resources
