Maximum amount of UE

[Rosario Patanè]

Hi all I would like to report that I'm trying to create a simulation with a large number of UEs, but the limit is forty. I tried to increase the number of UEs in the examples and this always gives the problem "NS_ASSERT failed, cond="it != m_enbRrcSapProviderMap.end()", msg="could not find RNTI = 0", +0.021071427s 28 file= /home/saro/NS3/ns-3-dev/contrib/nr/model/nr-rrc-protocol-ideal.cc, line=254" examples and I still have the same problem. Could anyone help me? Thank you

What example are you talking about? Is this 40 UEs per gNB or....?  Be more specific. 

Also, have you tried simply printing to check what RNTIs are created , if you got one per each UE you create? 

Or maybe just use the already implemented LOGs, log the PHY, MAC layer and see what happens with these 40+ UEs you create. 

best regards,

George

Hi

I'm facing the same issue ("could not find RNTI = 0") when increasing the number to 40 UEs per gNB. I'm using ns-3.42 with 5g-lena-v3.3.y.

The example where i  changed the number of UEs is  cttc-nr-simple-qos-sched.cc(you will find it below).

Can you please help me resolve this issue?

Best Regards.

Try to increase the SRS periodicity:

Config::SetDefault ("ns3::NrgnbRrc::SrsPeriodicity", UintegerValue (320));

BR,

Config::SetDefault("ns3::NrgnbRrc::SrsPeriodicity", UintegerValue(320));

I tried setDefault like this but I am getting the following error:
msg="Could not set default value for ns3::NrgnbRrc::SrsPeriodicity", +0.000000000s -1 file=/root/ns-3-dev/src/core/model/config.cc, line=899
NS_FATAL, terminating

Command 'build/contrib/nr/examples/ns3.42-test-nr-ue-default' died with <Signals.SIGABRT: 6>.

Can anyone guide me through this?

There is a typo in Gnb

Config::SetDefault("ns3::NrGnbRrc::SrsPeriodicity", UintegerValue(320));
