- In this video going to give overview of 5G-NR where i have covered
Multiple Numerology, mmWave, Massive MIMO, Beam Management, LDPC/Polar Coding, SDAP Layer in depth.
Multiple Numerology:
a) Numerology means 'Subcarrier Spacing’
In Simple term of 3GPP, we say 'subcarrier spacing type’
mmWave:
Millimeter wave, which is also known as extremely high frequency (EHF) or very high frequency (VHF) by the International Telecommunications Union (ITU), can be used for high-speed wireless broadband communications.
The exact frequency range for FR1 (sub 6 GHz) and FR2 (millimeter wave) are defined as below.
Massive MIMO
Massive MIMO - Why Massive MIMO?
We use very high frequency (mm Wave) signal in 5G. High frequency mean that the size of single antenna will be very small and the aperture (the area for receiving energy) will be very small. To overcome this small aperture on receiver side at high frequency, we need to use a large number of transmission antenna.
Beam Management
The current status it seems that most of the deployment would be in very high frequency (millimeter wave) and this high frequency deployment would be one of the most important characteristics of 5G (NR).
LDPC/Polar Coding
In LTE, Tail Bit Convolution Coding and Turbo Coding are the major technology for channel coding,
But in for 5G NR Low Density Parity Check (LDPC) coding is replacing the Turbo coding that was previously used for PDSCH coding and Polar Codes are replacing the Tail Biting Convolutional Codes (TBCC) used previously for PDCCH coding.
SDAP Layer
NR Radio Protocol Stack Architecture is almost same as LTE Radio Protocol Stack Architecture. If you are already familiar with LTE protocol stack or general concept of radio protocol stack, you would not need to spend too much time to understand this Layer.
Thanks for watching my Channel ATS.
I am working in wireless technology where what i learn same knowledge, technology and technical things shared with you in video format.
Apart from Technology my involvement in creating online money and also learn related to some technical and social things which is belong to my Learning Habit, I do not want to keep these things confined to myself.
I would be glad if my video would be a helpful for you.

Good information
Thanks
Anand Sir great video easy understand . thank you
Bhai chha gaye guru
Really nice tutorial ..it would be really great if you can cover topics like initial access in 5G NR , Mobility and detailed video on each topic covered today
Thanks
Nyc video sirr
Good Explanation,. Thanks. waiting for new video on 5G Rel 16..
Thanks Sisir
you are damm good teacher.....u explained really very well...!!
Thanks madhu
nice 5G tutorial, thank you.
Thans
Good video...
Nice tutorial
Thanks
Will be Helpful for Learners If You can add a Separate Video of 5G NR Massive MIMO technology only. In fact this video was very helpful to understand 5G NR. Thanks a lot :-)
Thanks Mangaldeep...Yes i am uploading separate video for every topic...
Thanks for Your comment...uploaded separate video for Massive MIMO
I have been searching 5G Info and so far this is best ..
can I get PPT ?
@Anand , please make another video how LDPC and Polar codes are actively using for beam management.
Could you explain how is no of prb calculated... In lte 20Mhz 100 prb is 106 in 5g consider 15khz scs.
excellent presentation. Please provide the slides if possible.
Hi, thank you for the video !
So means in concrete: When I have a fixed bandwidth (as in mobile communications) and I adjust a higher subcarrier spacing I have less channels but faster data transmission because of the more OFDM Symbols in one subframe. Is that correct ?
Yes fast data transmission mater on ofdm also
Really good explanation and overview. However, in some parts, it's hard to comprehend what is being said.
Thanks
Nice..
Thanks
good explanation sir & thanks for sharing Video
@@sharadsontakke3974 thanks
nice work
Thanks
U have worked realy hard. It seems u have a good understandings of the topic but It would have been better if u had explained all in hindi. Anyways thnx a lot..
Thanks for Advice....
How to remove subscribe button from the screen. Its hiding some part of the verbiage. Thanks.
sir could you explain prb calculation in 5g plz
Can you provide the slides as these are very helpful
Make videos on centralized radio access network, fraud hauling techniques
Sure
Very intresting presentation. Is it possible to share your slides ?
Thanks...please share ur email
@@AnandTechnoSolutions bpudasaini21@gmail.com.. Thank you in advance
Please share theses slide to radiofrequences@gmail.com thank you
Sir can u share ppt please
Email- arvind.gupta037@gmail.com
Hi, Thanks a lot for this detailed explanation. Is it possible to get the slides for these?
Only some part is explained using slide ...most of part is animated by software....
Please provide your email...
hello such a nice tutorial
plz can i got this ppt
Share yout email
I wish the guy talked in slowmo
change the playback speed to 0.75 in settings.
Very good tutorial. Pls add some tutorial on ,' RAN architecture '
in Next Video..Thanks
you could visit to these topics as well. these are well explained.
