Forming Spatial Reuse Groups in WiFi Networks

Abstract:

Generating access point-specific spatial reuse groups for a given access point (AP) includes identifying radio frequency (RF) proximate to the given AP. The given AP uses a predefined threshold value to compare against the received signal strength indicators (RSSIs) of detected signals transmitted by other APs to identify RF proximate APs. The given AP can broadcast a spatial reuse group bitmap that identifies the RF proximate APs so that stations associated with the given AP can determine whether to transmit in a channel that is already occupied by an AP.
