Communication methods and devices of wireless local area network, access point equipment and site equipment

Abstract

The invention provides communication methods and devices of a wireless local area network, access point equipment and site equipment. One of the communication methods of the wireless local area network includes: detecting dormancy period duration of secondary communication interfaces of all associated site equipment, which supports a WUR (Wake up Receiver) mode, according to a preset period; determining a maximum value in the dormancy period duration, and marking the same as maximum dormancy duration; determining bit quantity of a partial time synchronization function (PTSF) according to the maximum dormancy duration; generating a wake up beacon frame, wherein the wake up beacon frame includes the partial time synchronization function, and the partial time synchronization function is usedfor instructing the site equipment to carry out time synchronization; and sending the wake up beacon frame according to a preset time interval. Through the technical solution of the invention, bit length of a time parameter is dynamically adjusted, thus power consumption of a sender and a receiver is reduced, and at the same time, data transmission efficiency is also 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, mainly used in the Internet of Things, the purpose is to save the power consumption of the equipment 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 commu...

Problems solved by technology

[0005] In order to further reduce the power consumption of site equipment, it is defined that the secondary communication interface of the site equipment also supports periodic sleep mode. The secondary communication interface can receive downlink wake-up beacon frames in wake-up mode, and the wake-up beacon frames usually contain time Synchronization information (TSF, Time Synchronization Function) to indicate that the secondary communication interfac
