Finalize the AP power save specification in IEEE 802.11bn

Determine and standardize the final specification for access point dynamic power save in IEEE 802.11bn, including the definition of low‑capability and high‑capability operating states, transition triggers, and compatibility with legacy (pre‑802.11bn) stations.

Background

Section 6.3 introduces Dynamic Power Save (DPS) modes for both stations and access points in 802.11bn, noting that APs face unique challenges because they must remain compatible with legacy stations while reducing idle energy consumption.

The text summarizes multiple proposals (e.g., low‑capability listening with on‑demand high‑capability switching, STA‑triggered activation via Initial Control Frames, and TWT‑based schedules), but emphasizes that no single, finalized specification has yet been agreed.

References

At the time of writing, the final specification for AP power save remains open.
