[@WASSIM2024A]

@@OurTechPlanet of course, good luck

[@imthiyazali]

Great explanation. thanks for sharing knowledge. kindly make video on MLB settings.

[@OurTechPlanet]

Thanks. Sure, will try to cover load balancing in detail soon

[@georgioskarouzos7418]

Very helpful! If i am not mistaken, prerequisite for Mo-Data and Mt-Access is LTE attach(NAS signalling). I think that msg3 always includes Mo-signalling. Please confirm.

[@OurTechPlanet]

MSG-3 can be Mo-Sig or Mo-data or Mt-access. LTE Attach uses Mo-Sig.

[@georgioskarouzos7418]

Are there any Harq retransmissions for msg 5(RRC connection setup complete) ? Thank you

[@mallikarjunyeganoor1858]

Thank you so much sir... Please do videos of uplink frame structures with every symbol information.

[@OurTechPlanet]

Sure, we will plan them as well

[@ATTac-xr2nr]

Thank your this session. It's awesome!
Question on how RRC is affected by mobility? For example a site only covering a busy road:
Will the count be less since it just connects and goes and HO to another cell?

[@OurTechPlanet]

Yes that is possible. If most of the traffic is due to incoming handovers, then RRC Setup attempts would be lesser

[@muhammadshahzadafzal6229]

Thank you so much.Very good video. What is the exact name of the eNB Timer(in Huawei or ZTE)that starts upon sending the RRC connection setup message?

[@OurTechPlanet]

Sorry, we try our best not to provide vendor specific details :)

[@zeeshanzia4303]

Thanks...Very informative...!!! Pls Plan a session on LTE Throughput Improvement.

[@OurTechPlanet]

Thanks. Will plan that too!

[@katyal82]

Can u pls share your inputs on traffic balancing between different LTE Layers

[@OurTechPlanet]

Sure, we will plan a session on traffic management too!

[@m.karthikeyan6482]

Please post seperate video for events and Timer ..

[@OurTechPlanet]

Ok, will put that in the plan as well!

[@coolmunzir]

Which software do you use for screen recording during the session

[@OurTechPlanet]

Most of the sessions are recorded using power point screen recording.

[@sumantabhuin7433]

First of all thanks for the things making more easy as always. I have 2 questions. Could you please guide me?
1) if RRC Setup Failure Due To No Response and establishment cause is mo signalling then how from the trace analysis we can understand that eNB doesn't response the rrc setup complete msg from UE?
2) and how we can understand from the trace analysis that UE doesn't support the configuration incase of single UE issue?

[@OurTechPlanet]

1. So, from trace you can see RRC Setup is sent but no RRC Response is received
2. In case of UE issue, you would normally see repetitive RRC attempts

[@coolmunzir]

1. Can you provide the eNb end timer code (like T300) for RRC Connection Setup Complete Msg (5)
2. Regarding partial UL Band interference, you were referring to like move the PUCCH Band from either band edge or from the other end of PUCCH Band whichever is clean, right?

[@OurTechPlanet]

The eNB timer does not have a code, it has different names for different vendors.
Regarding interference I was referring to start PUSCH scheduling from un-interfered part of the band.
