Problems solved by technology

This will undoubtedly cause a delay for STAs to access the channel, thereby affecting the utilization of the spectrum and indirectly affecting the improvement of regional throughput.
[0007] Therefore, how to avoid the impact of the existing CCA rules on spectrum utilization and regional throughput by controlling the sensitivity of the receiver has become a technical problem to be solved urgently

Abstract

The invention provides a wireless local area network communication method which comprises steps of receiving a message frame and acquiring a received signal strength value of the message frame; selecting a smaller value from the received signal strength value and a preset received signal strength reference value; regulating receiver sensitivity of a message frame receiving side in real time according to the smaller value. The invention further provides a wireless local area network communication device. By means of the technical scheme, stations (STAs) or AP can regulate the receiver sensitivity dynamically in real time according to signal reception, therefore, reception ranges of the STAs or AP can be controlled, and spectral efficiency and regional throughput are increased.

Description

technical field [0001] The present invention relates to the technical field of wireless local area network communication, in particular to a wireless local area network communication device and a wireless local area network communication method. Background technique [0002] In 802.11, a new research group HEW (High Efficiency WLAN) was established in 2013.5 to study next-generation Wi-Fi technology, and the proposed vision is to increase throughput in the area and improve spectrum utilization. [0003] In an existing WLAN (Wireless Local Area Networks, wireless local area network) technology, a STA (Station, terminal) senses whether a channel is busy or idle through a threshold of receiver sensitivity (Receiver sensitivity). For example, in the 802.11n standard, under the condition of a channel bandwidth of 20MHz, the receiver sensitivity threshold is -82dbm. [0004] in such as figure 1 In the shown application scenario, STA1 and STA2 are associated with AP1 and AP2 resp...
