Sep. 2016 Re-Cap: HE Trigger-Based PPDU and SRP Trigger frame from STA2 (AP) for UL MU carries SRP, OBSS Color, and the uplink duration. Uplink STA (STA1) copies SRP from trigger frame into SR field of SIG A SR STA uses RSSItrigger frame from the trigger frame and SRP is in UL HE Trigger-based PPDU transmitted by UL STA to make adjustment for STA2 (AP) satisfying SR conditions. STA2 (AP) Trigger on-going frame Transmission STA1s UL MU UL MU STA1 (UL STA) Trigger frame carries SRP (not in SIG A) for UL STAs SRP (TriggerBased PPDU) UL _MU SIG A: SRP SR transmission duration TX_PWR adjusted based on RSSI and SRP .
