Search Space and CORESET configuration in 5G

[@ericmrozinski6143]

Indeed, the best explanation of the concept around PDCCH scheduling I have seen anywhere, including the '5G bible' "5G New Radio In Bullets". Thank you for your effort!

Best Explanation for CORESET

[@wallychen8765]

This video is the best video I've seen that introduces PDCCH.

Waiting for new video..very nicely explained

[@tuongnguyen9391]

Damn this is so so good. Can you do something about handover in 5g cellular network

[@VipinKumar-dv7hy]

Very informative..waiting for new video

AMAZING

[@sanjudas1759]

superb! 😀

[@infotechtvtyagi3953]

Thanks very informative….please explain srs antenna switching in details in one video

[@arv_sajeev]

Great videos, the graphics help a lot :), do you use manim or some other tool to prepare the visuals?

[@WirelessExplained]

For this video, I used After Effects.

Hi
This is very good and informative
Could you please make a video on DL synchronization in 5g

[@jorgeagosto6848]

Very good

As you mentioned , In 4G, on every slot, some 1 are 2 are symbols are reserved for PDCCH and remaining symbols are for data transmission..in that reserved symbols if we don't transmit PDCCH,the unused symbols can't be used for data transmission..
Coming to 5G , CORESET concept was introduced for PDCCH transmission
My query is like Can't we transmit PDCCH without CORESET?
In 5G, we can use that unused symbols in the PDCCH for data transmission purpose...
Can we do in this way like ..without having that CORESET for PDCCH transmission,can we use that unused symbols in the PDCCH for data transmission purpose?
How that CORESET will be placed in time and frequency grid? Is there any triggering condition or when the PDCCH data is available it will also be available at that time?

[@WirelessExplained]

UE search for PDCCH in all CORESET configured. If CORESET concept is absent, then UE has to search for PDCCH on a larger search space. CORESET is introduced to reduce the search space for UEs.
Time-frequency location of CORESET is informed by BS to UE via RRC messages 1:25 .

Thank you@@WirelessExplained

What is the reason of blind decoding of PDCCH? PROS and cons?

[@WirelessExplained]

Pros:
1) BS doesn't need to explicitly tell the location of PDCCH.
2) No dedicated resources for PDCCH, hence no resource wastage [0:49].
Cons:
1) Higher computational complexity (hence higher power consumption) for UE's blind decoding.

I didnt understand Interleaving and REG Bundle. Why is this neccessary when we already already know CCE is made of 6 REs? and Why is interleaving and cyclic shift used ?

[@user-pq2ob7mw7e]

You are 5g of god

[@user-fq9zt6pj7m]

More new videos...

[@jeffoh4793]

great explanation but the AI voice sounds a little off dont ya think? lol

[@yanpengyang8085]

How come the coreset longer than 3 OFDM symbols at 4:23?

[@WirelessExplained]

You are right. CORESET duration cannot exceed 3 symbols. The example at 4:23 is only for illustration purpose. Thanks for pointing this out 👍

[@keepursmile000]

Any new topics please
