Communication method and communication device for wireless local area network

Abstract

The present invention provides a wireless local area network communication method and a communication device, wherein the wireless local area network communication method includes: generating a communication resource allocation message frame, and determining the transmission power of the communication resource allocation message frame as the communication resource Allocating the maximum transmission power allowed by the sending sub-channel of the message frame, and determining that the modulation and coding mode of the communication resource allocation message frame is the minimum modulation and coding mode of the sending sub-channel; and sending the communication resource allocation message frame. The technical scheme of the present invention enables the wireless access point to accurately set the MCS and transmission power of the communication resource allocation message frame, thereby ensuring that STAs perceive and analyze the communication resource allocation message frame, and realizes the application of OFDMA technology in 802.11ax, effectively Improved spectrum utilization.

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 and a communication device of a wireless local area network. 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 spectrum utilization efficiency, the 802.11ax (HEW) task group will use OFDMA (Orthogonal Frequency Division Multiple Access) technology for data transmission, and STA (Station, workstation) for uplink data frame transmiss...
