Wireless local area network communication method and device, access point equipment and station equipment

Abstract

The invention provides a wireless local area network communication method and device, access point equipment and station equipment. The wireless local area network communication method comprises the following steps: generating wake-up beacon frames, wherein the wake-up beacon frames contain partial time synchronization information, and the partial time synchronization information is used for indicating that the station equipment performs time synchronization without waking up a main communication interface of the station equipment; transmitting the wake-up beacon frames; after sending a specified number of wake-up beacon frames according to a preset time interval, generating a beacon frame, wherein the beacon frame includes the time synchronization information, and the time synchronizationinformation is used to indicate that the main communication interface of the station equipment performs time synchronization; and transmitting the beacon frame. According to the technical scheme of the invention, on the premise that the station equipment supports a sleep mode, the probability of time asynchronization between the station equipment and the access point equipment is reduced, and thefrequency spectrum utilization rate and the data throughput are improved.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular, to a communication method of a wireless local area network, a communication device of a wireless local area network, an access point device and a station device. Background technique [0002] In July 2016, IEEE (Institute of Electrical and Electronic Engineers, Institute of Electrical and Electronics Engineers) 802.11 established the next-generation Wi-Fi (Wireless Fidelity, Wireless Fidelity) technology research group WUR (Wake up Receiver), namely IEEE (Institute of Electrical and Electronic Engineers, Institute of Electrical and Electronics Engineers) 802.11ba, which is mainly used in the Internet of Things, aims to save power consumption of devices as much as possible. [0003] A wake up frame is defined in the IEEE 802.11ba standard, its main purpose is to wake up the main communication interface of the communication device, that is, the communication de...

Problems solved by technology

[0004] In the related art, a WUR beacon frame (that is, a wake-up beacon frame) is defined, and the frame body part of the WUR beacon frame carries a PTSF (partial time synchronization function, partial time synchronization parameter), which is used to indicate that the secondary communication interface is in In sleep mode, it can maintain time synchronization with the access point. However, because the WUR frame carries some time synchronization information parameters, if the communication device is in sleep mode for a long time, it may not be able to completely solve the problem of time synchronization, and the main communication device of the site device There is no time synchronization in sleep mode, so the longer the sleep mode lasts, the more prone to loss of synchronization between the station device and the access point device
