Communication method, device, access point and station of wireless local area network

Abstract

The invention provides a communication method and a communication device of a wireless local area network, an access point and a station. The communication method of the wireless local area network comprises the steps of: generating a notification message frame, wherein the notification message frame contains corresponding judgment threshold information which is used for indicating different business types when equipment in a basic service set is executing a CSMA / CA mechanism, and the judgment threshold information is a basis for the equipment to judge whether a channel is busy when the equipment accesses data of the corresponding service types sent by the channel; and sending the notification message frame. The communication method and the communication device of the wireless local area network, the access point and the station can select the judgment threshold value when executing the CSMA / CA mechanism flexibly according to different business types, further can satisfy requirements of the different business types, especially the particularly urgent business types, and are conductive to improving repeated utilization rate of the frequency spectrum and regional throughput capacity.

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 and a station. Background technique [0002] In May 2013, 802.11 established the next-generation Wi-Fi technology research group HEW (High efficiency WLAN, high-efficiency wireless local area network), that is, 802.11ax. The main research points are to improve the throughput of existing Wi-Fi technology and increase the spectrum. Effective utilization efficiency, improve user experience and service quality QoE (Quality of Experience), and achieve a more dense communication environment than existing Wi-Fi technologies. [0003] In order to improve the efficiency of spectrum utilization, especially the reuse of space and frequency, a mechanism for changing CSMA / CA (Carrier Sense Multiple Access with Collision Avoidance, Carrier Sense Multi...

AI Technical Summary

Problems solved by technology

[0003] In order to improve the efficiency of spectrum utilization, especially the reuse of space and frequency, a mechanism for changing CSMA / CA (Carrier Sense Multiple Access with Collision Avoidance, Carrier Sense Multiple Access / Collision Avoidance) has been proposed in related technologies to Technical solutions to improve regional throughput, but there are no special regulations for CSMA / CA used by some different services, which may affect some particularly urgent services that cannot be handled well, such as voice services / video Business etc.
