Are- in case of DL RLC retransmissions- HARQ retransmissions also taking place (alternately)? The aggregation level(PDCCH resources) should be also increased, correct?
Yes HARQ retransmissions happen at MAC/PHY while ARQ is at RLC. Usually once all HARQ retransmissions are done then a RLC retransmission takes place. The PDCCH resources and Aggregation Level change can be linked to HARQ retransmissions but this is implementation specific and different vendors use different algorithms to control this.
What if I start from UE first switched ON and it starts scanning the COMPLETE BW , then filter out best EARFCN . I mean RSSI scan, can I start explaining from there. Then going to PSS and SSS?
Nice video, Need more information- How to move user from High band to Low band or vice versa. Also if possible please share How many types of Load balancing we can do(Capacity or Coverage base and how). It would be great help...Thanks
In Event A5 why didn'y you include the concept of Hystereis. Will the interviewer not ask what exactly is the difference between A4 and A5 then.... Why if the interviewer asks, whats the purpose of keeping 2 same events for Inter frequency HO?
Hysteresis is there for all handover events. Regarding A4 and A5, the A4 is a single event and needs to work with another event like A2. While A5, usually has two steps, A5-thresh1 and A5-thresh2 which adds more flexibility for the designer.

I think HO drop , we can increase X2 Reloc overall timer as well.
@@swarnban8634 Yes, that can work in certain scenarios as well!
Bundle of thanks,finally some one who take care for RF guys:))
Welcome, Glad that it helped :)
Thanks pushing out detailed and technically relatable videos so rich in content. God bless you immensely
That is great to hear. Thanks a lot :)
Thank You very well explained.
Glad you liked it
Precise & Detailed Explanation !!!
Thanks!
Again the best 🙏 like always!
Thanks again! :)

Nice sir
Excellent
Thank you! Cheers!
Good.❤
Thanks
Welcome 😊
great session...superb
Thanks!
Thanks Dear.... Always your videos give some extra fruits ....nice and simple explanation ....now i am waiting for 5G part Haha haha....
So nice of you. Soon!
Can u pls make similar one for 5G
Yeah, it is in the making :)
Good work
Thanks
Hi, can you discuss layer 3 message in LTE
Have a look at this playlist, it covers many of the LTE call flows and L3 messages

Thanks Dear , can you please make one video for pci mods 3,6,30
Sure, will put it together and share soon!
can u make similar NR interview questions with answers.
There are a few already under the following playlist

Thanks
You are welcome!
Thanks for sharing this, very helpful 👌🏻
Glad it was helpful!
Thank you very much, very helpful.....can you plz make part-2 which include MLB & VoLTE optimization parameters.
Thanks. Sure, will work on that!

Can you do a 2nd part for it dedicated to VoLTE
Sure, will work on that too

Have a look at this article where I have explained this process

Sure, will add this to our list :) Stay tuned!

Well explained .. can u plz share NSA AND SA CALL FLOW
Have a look at this playlist, I have covered some of the call flows over there
ua-cam.com/play/PL4OXTttOk9WhvApKwJBcZx0G4a2m8N-z6.html
N310/T310 values answer might seem irrelevent as the timer values are standardized and cannot be changed for a few cells.
Depends on network, many networks have different values.
🙏🙏🙏🙏
Thanks
Handover explanation is very basic
Source to target
Path switch all are missing
Please more elaborate
If the question is about handover call flow then we do discuss about path switch but here the question is about events and their description only.
@@OurTechPlanet please make one detail video about
Handover
Through put
CA
With lab setup and log analysis
It will very informative
Thanks
