Problems solved by technology

[0007] for figure 1 In the communication scenario shown, if the technology in which the BSS color value remains unchanged in 802.11ah is used in data transmission, it will not only interfere with its own communication, but also not adapt to the CCA (Clear Channel Assessment, channel idle detection) value. Changing mechanism (due to reduced or larger BSS range or changing CCA value)

Abstract

The invention discloses a wireless local area network communication method and communication device, and an access point and a website. The wireless local area network communication method comprises steps of generating a first data frame at a first time point, wherein the physical frame head of the first data frame carries a first color value of a basic service set, generating a second data frame at a second time point, wherein the physical frame head of the second data frame carries a second color value of the basic service set and the first color value is different from the second color value, and transmitting the first data frame and the second data frame. Through the technical scheme of the invention, the BBC color can be regulated according to a practical communication environment, the BBS color value is guaranteed to be applicable to an 802.11ax application scene and an area handling capacity is improved.

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 the process of standard formulation, the SIG-A field in the physical header of the PPDU (Physical Layer Convergence Procedure (PLCP) Protocol Data Unit, Physical Layer Convergence Procedure Protocol Data Unit) w...
