Herbert’s point about wireless indicating changes is exactly the problem
we have been working on. Mikael’s draft covers the ISP informing the RG
of the access rate; the wireless side is the complementary, and much
faster-moving, half of that picture.
The goal of Fi-Wi is to make Wi-Fi and the WAN link a coupled,
control-theoretic system, using the TXOP as the fundamental unit of
wireless work. Scheduling, queue management, and rate adaptation can
then be coordinated across both sides of the access path using real-time
state rather than having each layer guess independently.
This simulation illustrates the challenge:

The values are simulated, not measured, so please treat it as a
visualization rather than an experimental result.
I discussed the approach in this DPDK presentation:
