NS3 User Documentation update - TransmissionModeConfigurationUpdate

[Ramakrishnan]

Hi, 

I think the NS3 User documentation requires a re-check - post CA code inclusion into NS3 build, 

I noticed an issue with example code around "TransmissionModeConfigurationUpdate", wherein code marked in RED had to be updated.

--> It should be lteEnbDev instead of  enbNetDev and GetCcMap()[0] should be called to get the correct component carrier.   

Additionally the simulator crashes if  "TransmissionModeConfigurationUpdate" is called during data transmission and HARQ is enabled. Has this been used/tested before?

Thanks, 

Ramakrishnan

*************code********

Ptr<LteEnbNetDevice> lteEnbDev = enbLteDevs.Get (0)->GetObject<LteEnbNetDevice> ();

PointerValue ptrval;

//enbNetDev->GetAttribute ("FfMacScheduler", ptrval); --> Code in User documentation 

lteEnbDev->GetCcMap()[0]->GetAttribute ("FfMacScheduler", ptrval);

Ptr<PfFfMacScheduler> pfsched = ptrval.Get<PfFfMacScheduler> ();

if (pfsched == 0)

{

   NS_FATAL_ERROR ("No Pf Scheduler available\n");

}

Simulator::Schedule (Seconds (0.04), &PfFfMacScheduler::TransmissionModeConfigurationUpdate, pfsched, rnti, 1);

Hello Ramakrishnan,

I am trying to use this "TransmissionModeConfigurationUpdate" function , but I am getting the sent below error even when I added the updates you've sent.

Program received signal SIGSEGV, Segmentation fault.

0x00007ffff6651b52 in ns3::RrFfMacScheduler::TransmissionModeConfigurationUpdate (this=0x0, rnti=0, txMode=0 '\000')

    at ../src/lte/model/rr-ff-mac-scheduler.cc:1860

1860   m_cschedSapUser->CschedUeConfigUpdateInd (params);

And, another question is about where exactly in the code we have to place this function?

Thanks a lot in advance.

Salwa.
