  • ADAPTIVE THRESHOLDS FOR SPATIAL REUSE
    Publication number: 20220377679
    Abstract: Transmission thresholds for IEEE 802.11ax Spatial Reuse (SR) opportunities are set adaptively. A group retry rate is defined and used to quantify the level of interference in a Spatial Reuse Group (SRG). Access points in the SRG update their OBSS-PDmax thresholds so as to keep the group retry rate value acceptably low. Access points transmit during an SR opportunity subject to the constraints imposed by the updated OBSS-PDmax.
    Type: Application

  • Forming Spatial Reuse Groups in WiFi Networks
    Publication number: 20220225474
    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.
