NR5G HARQ: Concept and basic implementation (Hindi Audio / English Subs available)

[@kronos3able1]

exceptional way of explaining the HARQ. Thanks for great video :)

[@shaileshkaushik]

Thanks a lot..!!

[@ashishjain5470]

I was creating PPT on HARQ 5G and this content is really really good. Thanks Kaushik Sir. Please make video on Open loop and close loop Power Control- 5G . How IEs impact and their relevance

[@shaileshkaushik]

Thanku for dropping in and a big thanks for dropping a comment...keeps me going..also, just a query....Are you from KIET ghaziabad?

[@rajkumar45das]

AP jaisa samjane wala koyi Mila nahi.hum bhi ye topic ki opor Kam krta hu doubt bhi bohot hota hai or sath sath English me pura acche se samaj me nahi ata.agar ap is 5g topic me thoda or jyada video upload krenge to mere jaise bahot ko upkar milega sir.
Thank you sir.

Mehnat karte raho and lage raho... sab samajh aa jayega....
Aur angrezi par bhi dhyaan do... Jeevan mai aage badhne k liye bht aavashyak hai... Kaam ayegi...

[@rajkumar45das]

Bas sir ak hi request ap jitna bhi lecture de 5g k basis pe ho sake to upload krte rehena.
Thank you sir.

[@TheAbdulj6]

Very very good way of teaching ❤

[@shaileshkaushik]

very very nice to get appreciated for that...

It's to much helpful ,but sir where we use adaptive re-transmission and non-adaptive

[@shaileshkaushik]

There are no non-adaptive transmissions in 5G.
Non-adaptive can only happen in case HARQ is synchronous, so you know before hand which resources(FREQ-TIME domain) to use.
In LTE UL retransmissions are synchronous , so non-adaptive CAN happen there (Adaptive can also happen).
But in case of 5G, both UL and DL harq are asynchronous so there is no scope for non-adaptive transmissions.

Very informative 😄

Thanku mam..

Thanks Sir for sharing

[@vishwasrasal2098]

Very informative!

[@shaileshkaushik]

Bht Dhanyavaad Sir..!!

[@infotechtvtyagi3953]

Hi plz schedule next video on this it’s was very informative…..hard with code base

[@amitsatija552]

Thanks for sharing. Very interesting and clear. One question though, gNodeB (supporting 32 UEs and 2 UEs per TTI) can schedule upto how much HARQ bits of information in one TTI for multi UE scenario. Is there any formula to calculate and how does it change with the Pattern A and Pattern B

[@shaileshkaushik]

As per 38.213, the max length od UCI field can be 1706 bits.. As much as I understand it there is no division if it could be HARQ cmpletely or if thee is any cap on HARQ within this length...
I do not understand the question about pattern..

At 11:18, interleave or channel coding jo bola he wo security k liye nahi hoti right. kyuki security k liye to encryption hota he. interleaver and channel coding ka purpose to alag he, right.

[@shaileshkaushik]

depends on what you mean by security... All these methods are meant for the security of data.... When you say encryption ( Ciphering), you mean the security in a way that no one can access the data except sender and receiver, So in a way it is to maintain secrecy...
whereas, channel coding etc are the methods that ensure that data transfer over the air happens without errors... here also you're securing the data.. it is like transporting a bone-china set with proper security... you need security so it does not break but it is not really controversial if it is sent in a transparent packaging (i.e. without ciphering).
but if you are a 70s bollywood movie smuggler transporting cocaine... it may not need padded packaging, but you would not want everyone to see what is inside... so you would want to cipher here....
So all these procedures are there for securing the data but different manner.
