Problems solved by technology

Due to the above-mentioned evaluation requirements, if there are 60 devices supporting WUR mode, they need to receive unicast WUR message frames within 30 minutes, but considering that in a BSS (Basic Service Set, basic service There may be a large number of STAs (Stations, station equipment) in the set), and there may also

Embodiment 1

[0059] Preferably, the first group of working frequency bands and the second group of working frequency bands both include the first frequency band and the second frequency band, then step 106 can be specifically executed as: judging whether the data transmission channel works in the first frequency band; if so, determining the WUR transmission channel Work in the second frequency band, otherwise determine that the WUR transmission channel works in the first frequency band.

[0060] In this embodiment, when both the access point device and the station device support the dual-band working mode, that is, the first group of working frequency bands and the second group of working frequency bands supported by each include the first frequency band and the second frequency band, then for Effectively distinguish the WUR transmission channel used to transmit wake-up message frames from the data transmission channel used to transmit data, to avoid communication conflicts, you can set the...

Embodiment 2

[0064] Preferably, one of the first group of working frequency bands and the second group of working frequency bands is a dual-band, and the other is a single-band, then step 106 can be specifically executed as: before the main communication interface of the site equipment enters a dormant state, communicate with the site equipment Negotiate to determine the WUR transmission channel.

[0065] In this embodiment, when only one of the access point device and the station device supports the dual-band working mode, that is, one of the first group of working frequency bands and the second group of working frequency bands supported by each is dual-band and the other is single-band. Frequency band. At this time, the access point device and the station device need to communicate on the same frequency band. In order to effectively distinguish the WUR transmission channel used to transmit wake-up message frames from the data transmission channel used to transmit data, and avoid communica...

Abstract

The invention provides communication methods and communication devices of a wireless local area network, an access point device and a station device, wherein the communication method of the wireless local area network for the access point device comprises the following steps: generating a wakeup message frame, wherein the wakeup message frame is used for waking up a main communication interface ofthe station device to receive downlink cache data; acquiring a first group of working frequency bands supported by the station device; determining a WUR (Wake Up Receiver) transmission channel used for sending the wakeup message frame according to the first group of working frequency bands and a second group of working frequency bands supported by the access point device, wherein the WUR transmission channel is a channel which is different from a data transmission channel of the access point device; and sending the wakeup message frame to the station device on the WUR transmission channel. According to the technical scheme in the invention, communication conflicts in the channel can be effectively avoided from occurring, so that the equipment is more power-saving and meets the requirementof IEEE 802. 11ba.

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, an access point device and a station device. Background technique [0002] In July 2016, IEEE (Institute of Electrical and Electronics 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 802.11ba is mainly used in the Internet of Things. The purpose is to save the power consumption of the device as much as possible. The most important thing is to make the device that receives the wake-up frame (wake-up message frame, WUR message frame) The power consumption of the device, where the power consumption required by the device to receive wake-up frames is not greater than 1mW. [0003] When the device is...
