Problems solved by technology

[0003] In the data transmission of the existing WLAN system, only one MCS (Modulation and Coding Scheme, modulation and coding strategy) mode can be configured for one channel, that is, each subcarrier of the wireless receiving end in the channel adopts this modulation Coding method, using the same modulation method for all these sub-carrier channels leads to waste of channel gain on sub-carrier channels with high channel gain, while on sub-carrier channels with low channel gain, bit errors are prone to occur, and it cannot be received according to each wireless The channel environment of each subcarrier channel of each wireless receiving end flexibly changes the modulation and coding method of each subcarrier at the wireless receiving end, thereby reducing the quality of communication transmission and the throughput of the WLAN network (the number of successfully transmitted data per unit time)

Abstract

The embodiment of the invention discloses a WLAN communication method, a related device and a system. The WLAN communication method comprises the steps of: generating a modulation encoding method configuration message frame which contains subcarrier modulation encoding method information of a plurality of wireless receiving ends, wherein the subcarrier modulation encoding method information of the plurality of wireless receiving ends can be the same or different, and the subcarrier modulation encoding method information of the plurality of wireless receiving ends are used for carrying out communication in a same channel; and sending the modulation encoding method configuration message frame. By adopting the WLAN communication method, the related device and the system, the subcarrier modulation encoding methods of the different wireless receiving ends can be different.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless local area network communication method, a related device and a system. Background technique [0002] With the advancement of information and communication technology, various wireless communication technologies have been developed recently. Among these wireless communication technologies, WLAN (Wireless Local Area Network, wireless local area network) is a wireless technology that transmits data, voice and video in the air. Signal technology. Currently, 802.11 establishes a next-generation wireless high-fidelity (Wireless Fidelity, Wi-Fi) technology research group—high efficiency wireless local area network (High Efficiency WLAN, HEW), so as to improve the throughput of current wireless communication. [0003] In the data transmission of the existing WLAN system, only one MCS (Modulation and Coding Scheme, modulation and coding strategy) mode can be configured for o...
