US Patent 11683835 Spatial reuse for high priority traffic

Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for reducing channel access latency via selective application of SR for latency-sensitive and high-priority traffic. If a radio frequency (RF) signal is detected on a channel used by an access point (AP) or a client device, a determination can be made as to whether the energy of the RF signal relative to SR energy level thresholds permits transmission on that channel used simultaneously by another, e.g., neighboring AP. If so, frames can be transmitted so long as the other neighboring AP is associated with a different basic service set (BSS) color than that of the AP, and so long as the frames to be transmitted belong to a high-priority/low-latency traffic access category.
