Finally, in stage 4, the Scheduling Master examines various factors affecting the APs in the OBSS and in the same BSS. For example, the Scheduling Master can evaluate the client activity, current RU assignments, and the OFDMA schedule across all OBSS APs. Based on each AP's activity level, the Scheduling Master can attempt to assign non-overlapping Resource Units (RUs) across the OBSS APs. This assignment schedule is done to synchronize RU use across the OBSSs to limit the amount of interference. The Scheduling Master continually monitors the activity level and may reassign RU blocks to different APs as necessary. If non-overlapping RU space is not available across these APs, the Scheduling Master may initiate a synchronized Inter-AP UL and DL transmission schedule for each AP (to ensure both AP and STA transmissions do not interfere with each other). Once the schedule is created on the Scheduling Master, the schedule is published to the slave APs and can be implemented. It should be noted that the schedule can be generated on a controller instead of an AP. Further, the Scheduling Master does not directly control the other APs. Rather, the Scheduling Master can create a time synchronized schedule and publishes that schedule to the Slave APs for them to use, if desired.
