Abstract
Embodiments of the present invention are drawn to methods and electronic devices capable of performing coordinate spatial reuse for wirelessly transmitting data on a channel in coordination with another wireless AP operating an overlapping BSS using the same wireless channel. The device can perform RSSI measurements and generate Per-RU RSSI reports including the RSSI measurements information for transmission to another wireless AP. The RSSI measurement can be performed by the device based on power levels detected when receiving TB PPDUs transmitted by wireless STAs responsive to trigger frames, for example. Based on the Per-RU RSSI report, a wireless AP can be configured to transmit data to an associated wireless STA without causing significant interference when another AP of the overlapping BSS is also transmitting, and can schedule frames for transmission from associated wireless STAs accordingly.
