Communication methods, communication devices, access point device, and station device

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...

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 be OBSS (Overlapping Basic Service Set, overlapping basic service set), then if the WUR message frame is still the main data communication between the AP and the STA Channels for transmission will inevitably cause communication conflicts, which is not conducive to power saving of equipment, and also causes waste of spectrum
