When scheduling a Downlink Assignment on the UL-TBF we need to make
sure that the assignment is sent _before_ the final ack. With my fairness
changes it gets more likely that this event is trigerred.
+After receiving an ACK/NACK.. schedule another one if the window
+is kind of stalled anyway. This way we avoid resending frames that
+might have already arrived. It could increase the throughput..
+Do not re-transmit after we got ack/nacked and where in the resending
+mode... and increase the window.

+Figure out scheduling issue. Why do we reach the 20 re-transmits and
+stil haven't received the ACK/NACK? was it scheduled? The whole
+scheduler could be re-worked to be more determestic.. and answer
+questions like if it has been sent or not
