@@OurTechPlanet Kindly publish videos on optimization of Retainability/Integrity/Mobility respectively for each with 3-4 practical supporting parameters changes done in different Vendors
@Our Technology Planet wants asking for vendor specific details but that fact that 6 months ago you said the next video is I. Progress, so wanted to ask if any possibility on that :)
Considering the fact that VoLTE already uses a very small DRX cycle of 20 to 40ms with a packet interval of 20ms, so I do not think that short DRX cycle will give much gain
Apologies for multiple queries. 1=> There will be drxinactivity timer as well in case UE detects PDCCH and UE will be in wake-up state for a bit more longer to receive retransmitted packet, is it ignored here for simplicity purpose? 2=> Regarding the example of Apple Handsets, TTI Bundling was assumed to be enabled right? 3=> In TTI Bundling Threshold modification, there is a possibility of two distinct packets being sent as well? 4=> Can this be said that with Delay Based Scheduling, good CQI packet can also get scheduled because delay is calculated purely based on packet stay in buffer and nothing to do with CQI but on most of the occasions it will be the poor CQI packet having higher delay in the buffer. 5=> Delay Based Scheduling is more suited to VoLTE Packet but is this best scheduling scenario for Data Packets?
5. Delay Based is good for any service which has a lower Packet Delay Budget. Since data packets do not have a low PDB so it might not be the best algorithm choice for data packets.
Hi, i have a question, you just point out kn video that there is retransmission packet for qci1, why? I suppose that there should not be any retransmir because of UM transmission
QCI1 retransmissions are on HARQ. The UM mode is on RLC and hence, there are no retransmission on RLC for QCI1 but there will still be retransmissions at HARQ layer (MAC/PHY) for QCI1 traffic.
So it means several copies of data is transmitted on air which is harq concept, without considering tti bundling, am i right ? This could reduce bler alot
First of all thank you so much for a very descriptive and easy explanation. So the main reason for improving UL quality/UL BLer/delay after enabling SINR/BLER based TTI bundling with a higher value for instance (SINR-7), will actually help UE to go into non DRX/always ON mode, and take advantage of non-DRX state as well .. Since they are mutually exclusive..right?

Good explanation..
Hello !! The sessions are very useful. Pleas restart. Thank you.
Thanks. We will plan something soon.
Do you have a complete course for every topic (4G and 5G) that we can take? I like how you explain everything clearly, you're a great teacher.
Thanks a lot. Not at the moment but in future, we do have plans to create detailed courses. We will share once they are ready and available :)
Any progress with it?
Can you pls create a explaination video on Volte IMS architecture..
Very useful session , when you will publish session 4 on pdcch for volte
It is in the pipeline but might take some time :)
Thank you it was a verh good video, what about the session 4 ?
Thanks! Session-4 is Still Work In Progress.
@@OurTechPlanetany update for further volte sessions?
Last portion you mentioned there will be more videos to explain how PDCCH to improve MOS, what is name of video?
That is still not published. Work in progress!

@@OurTechPlanet any possibility to get those in ?
@@fahadhafeez-io6cm Actually, as a principle, we try not to include vendor specific information.

Thanks, good explain, but please share your idea reagrding using short DRX for volte QCI 1

1. Yeah for the sake of simplicity, it was ignored.
2. Yeah TTI Bundling should always be enabled in commercial networks
3. Yeah different packets can be sent
4. This is quite possible as well because delay is the most important parameter in this case.
5. Delay Based is good for any service which has a lower Packet Delay Budget. Since data packets do not have a low PDB so it might not be the best algorithm choice for data packets.

@@raminsabzalizade4629 Yes that is correct.

Yeah, it helps in quality improvement :)
