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

Abstract

The invention provides a wireless local area network communication method and device, access point equipment and site equipment. The communication method comprises the following steps: determining a multiple value between a maximum wake-up period of the site equipment and the transmitting time of a target beacon frame; and generating and transmitting a change management message frame according tothe multiple value, wherein the change management message frame is used for notifying the site equipment that a BSS color value has been updated, wherein the change management message frame is used for carrying BSS (Basis Service Set) color value change information, and the multiple value is equal to a BSS color value change reciprocal counter value included in the BSS color value change information. Through the technical scheme of the invention, the occurrence of communication conflicts is reduced, and the spectrum utilization and the throughput of a basic service set are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, 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 May 2013, IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 802.11 established the research group HEW (High efficiency WLAN, high-efficiency wireless local area network), that is, IEEE802.11ax, the main research points are to improve the throughput of existing Wi-Fi technology, improve the effective use of spectrum, improve user experience and service quality QoE (Quality of Experience), and realize Adapt to denser communication environments than existing Wi-Fi technologies. [0003] The above-mentioned denser communication environment means that there are more OBSS (OverlappingBasis Service Set, crossed basic service...

Problems solved by technology

[0006] In related technologies, in order to reduce the power consumption loss of site equipment, a PS (Power Saving, power saving) mode is proposed, that is, when the standby time of the site equipment reaches a preset time, it enters a sleep state, and the access point equipment will Caching downlink data frames for site devices, however, how the access point device can promptly and effectively instruct site devices supporting power saving mode to synchronize BSS color value change information is not clearly stipulated in IEEE 802.11ax
