Trouble with TD/FD TBFQ scheduler

[Muhammad Attique Atta]

I'm executing simple lena ecp scripts by changing different schedulers one by one, but TD and FD TBFQ are working unexpectedly. 

They are showing packet loss 100% on each flow from Remote Host to all UE's.

I'm running dev version of ns3.

Let me know which information you require. Thanks

I'm using scheduler like this just after creating eNB.

//Change Scheduler technique to FD TBFQ

lteHelper->SetSchedulerType ("ns3::FdTbfqFfMacScheduler");  // FD-TBFQ scheduler
Config::SetDefault ("ns3::FdTbfqFfMacScheduler::HarqEnabled", BooleanValue (false));

//Change Scheduler technique to TD TBFQ

//lteHelper->SetSchedulerType ("ns3::TdTbfqFfMacScheduler");  // TD-TBFQ scheduler
//Config::SetDefault ("ns3::TdTbfqFfMacScheduler::HarqEnabled", BooleanValue (false));



//Change Scheduler technique to CQA
//Config::SetDefault ("ns3::CqaFfMacScheduler::HarqEnabled", BooleanValue (false));
//lteHelper->SetSchedulerType ("ns3::CqaFfMacScheduler");  // CQA scheduler

With td-tbfq

Hi Ateeq,

which ns-3 version are you using?

Thanks,
