Hello everyone,

I've set up a topology with 5 eNBs and a variable number of UEs. I'm trying to observe the throughput performance for different QCI categories. However, it remains the same, even when I use the CQA scheduler. I also applied the patch mentioned in this thread - (https://groups.google.com/forum/#!searchin/ns-3-users/$20Question$20regarding$20Dedicated$20Eps$20Bearer$20and$20handover$20%7Csort:date/ns-3-users/RvoYMP5uUso/zYaZj8noAgAJ).

Can someone help me figure this out? The EPS bearer can be modified in lines 404-405. The following line can be used for running the program:

./waf --run "scratch/lte-sample --nUE=40 --scheduler="ns3::CqaFfMacScheduler""

Thanks!

The scheduler will just prioritize who gets their RBs first, but if there's no congestion, the throughput will be the same no matter what is the bearer class.
Moreover, if all the UEs use the very same bearer type, they'll all compete evenly.
Logic...
