Abstract

The invention provides a communication method and a communication device of a wireless local area network, an access point and a site. The communication method of the wireless local area network comprises the steps of generating a notice message frame which comprises first information used for indicating a transmission period of a communication resource distribution message frame, wherein the first information can instruct a site supporting an OFDMA function to periodically contend for an access channel in an OFDMA random access contention period; and sending the notice message frame. According to the method, the access point can inform the site of the transmission period of the communication resource distribution message frame, and then the site can define the transmitting time of the communication resource distribution message frame, and meanwhile the site can adopt an OFDMA withdrawing mechanism before transmitting UL OFDMA data, thus the sites are reduced in mutual conflicts when transmitting uplink data, and the use factor of the frequency spectrum is indirectly 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 (Wireless Fidelity, wireless fidelity) technology research group HEW (High efficiency WLAN, high-efficiency wireless local area network), namely 802.11ax, the main research point is to improve the existing Wi-Fi technology Throughput, improve the effective use of spectrum, improve user experience and service quality QoE (Quality of Experience), and achieve a more dense communication environment than existing Wi-Fi technology. [0003] In order to make more effective use of spectrum resources, OFDMA (Orthogonal Frequency Division Multiple Access) technology will be adopted in the 802.11ax standard; and in the process of standard formulat...
