Hi,
when using SimuLTE in the following two scenarios I observe some interesting behaviour:
* Some nodes send 10KiB every 2s to the eNodeB.
* A subset of those nodes sends larger packets to the eNodeB (~70-150 KiB).
In the first case, the packets arrive on time while in the second case the large packets get a huge delay (up to 30s) and after the simulation the throughput measured at the eNodeB is much smaller (both scenarios use UDP). Note that, in both scenarios, all nodes regularly (every 1s) send very small packets, i.e., a few bytes, to the eNodeB. I assume this is because of the scheduler, but changing the scheduler type only has a minimal effect.
Do you have any ideas why this happens and if this is intended behaviour?
Best regards,
Florian Hagenauer
