Mirja, Sebastien, Isabelle,
This paper describes how congestion signals should be calibrated to
make them equivalent between radio resources and fixed resources:
Resource Control for Elastic Traffic in CDMA Networks
It also addresses the radio timescale problem Mirja just mentioned
(from the mic in the ICCRG meeting). It uses two control loops:
1) a tight power control loop for the radio resource (layer 1),
2) where there is persistent congestion at L1, it drives congestion
marking that is fed from L2 up to L3 and via TCP feedback to L4 as
part of the slower e2e control loop.
In addition, the hyperlink below gives a few other related papers
from the same team, particularly one relating to 802.11 rather than WCDMA.

>The Mobicom one is the most relevant for you.
