performance of profile between Delay and Cwnd to emulate dynamic of bottleneck bandwidth in a shared queue

[ktxu1224]

Hello, @yzaki @joerango @francisyyan @thp-comnets
I am recently reading your paper "Adaptive Congestion Control for Unpredictable Cellular Networks", and I can understand that in wireless scenario where there is separate queue for each UE, so the profile between Delay and Cwnd could be used to emulate the dynamic of bottleneck bandwidth. But I wonder what if multi UEs share the same queue at the bottleneck, can we also use the profile between Delay and Cwnd measured on each UE side to measure the dynamic of bottleneck bandwidth?

The second question is if it is not true, Is there any advanced method to emulate the dynamic of bottleneck bandwidth?

Many many thanks,
