Abstract

Embodiments of the present invention provide a frequency multiplexing method and a related device. The method in the embodiment of the present invention includes: the access point sends a first message to the station, and the first message carries indication information that the basic service set is in the fractional frequency reuse mode; the access point receives the second message sent by the station. message, the second message carries indication information that the station supports the fractional frequency reuse mode; after the access point determines that the station supports the fractional frequency reuse mode according to the second message, the access point Communicating with the station in a fractional frequency reuse mode. The embodiments of the present invention can effectively reduce frequency interference in a Wi-Fi network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a frequency multiplexing method and a related device. Background technique [0002] One of the most important influencing factors in wireless communication networks is interference. Due to the mutual interference of adjacent cells in the network, the capacity of the entire network is limited. With the development of wireless communication, various interference processing methods have been invented to deal with interference problems in different scenarios. There are many methods for dealing with interference, such as: interference avoidance, interference alignment, cooperative transmission, cooperative beamforming, and so on. Among them, interference avoidance is the simplest and easiest method to implement. [0003] An initial interference avoidance method is frequency reuse, that is, by using non-overlapping frequency bands between adjacent cells, using the four-color pr...
