5G NR Physical Layer : Frame structure, Flexible sub-carrier spacing, time slots and Resource blocks 

You are great teacher, well explained, I didn't think that this topic is that easy, you make it very easy 🤯😃

I am beginner for the NR physical layer.Very helpful to me thanks

Thank you, short and efficient.

Thanks for the great tutorial. Easy to follow.

excellent and brief explanation. Thanks

Thank you... For this simple overview of 5G Phy layer. We are waiting for upcoming videos..

Incredible. Muy buen vídeo señor.

Very well Explained ! !

Thank you so much Sir..This was really informative

Thank you . Very well explained.

Beautiful explanation. Thank you..!

thank you so much , helped me a lot . Can you please make a video on PDSCH processing

Easy explanation thanks

Simple and precise

Very helpful video. Thank you. I just recommend you to make the audio a little higher, for the rest is perfect

really good lecture sir.

Excellent explanation. Please correct the slot cout it's 2power 4 for the u 4 not 2 power 8.

Voice is very low sir. Required to improve audio quality. TQ For knowledge sharing..it's an simply awesome

Great work...Can you please make videos on 5G NR MAC LAYER as well

Thank you for the information. What actually means by number of Resource Block ? In LTE, i did not see info on the number of resource block. I understood in Frequency domain, we can have a maximum of 180KHz (15Khz x 12). In 5G, we can have from 180Khz to 2880Khz (240KHz x 12). Where does number of resource block come into picture

Good job brother. This was really helpful 👏 One question.. More number of slots reduce the latency. What helps increase throughout in 5G?

In the 15khz subcarrier slot per subframe is 1, and the slot contains 14 OFDM symbols. for In 30khz subcarrier slot per subframe is 2, each slot contains 14 OFDM symbols, then what size of each slot and the size of 1 subframe? In 60khz subcarrier slot per subframe is 4, and each slot contains 14 OFDM symbols, then what size of each slot and the size of 1 subframe?

how prb number varies for a fixed bw and fixed numerology?

Can you please explain how to calculate Guard Band for 5G?

Very nice video. You just mistakenly written 2 rest to 8 to while showing time slot with 'u' factor.

Hi, thanks for the video, one question, when we increase SCS from 15KHZ ( one time slot/14 OFDM synmbols ) to suppose 240KHZ (16 time slots / 16x14 OFDMS symbols within the same subcarrier , iznt throughput will increase in same fashion ( x16 times) as we have 16*14 OFDM symbols now compared to legacy 15KHZ case with only 1X 14 OFDM symbols ?

It is useful. But just that I couldn't see the resource grid info, even though the snapshot of the video shows about 5G NR resource grid. I think the snapshot of the video is misguiding. :( Actually I was looking for info. on how the mixed numerology works within the same symbol period. I am confused since the symbol period of 15KHz and 30KHz are different. so how both mu=0 and mu=1 would coexist in the same symbol period. Please reply if there is a video on that

In higher frequency bands > 24 GHz( mm waves ) ,ultra low latency can be achieved using higher sub carrier frequency spacing with multiple numerology…But in 5 G low band less than 1 GHz ,how this ultra low latency can be achieved ?

Thank you! Very useful. I have a question. what is the trade off when using higher SCS? Is it reliability? Does a shorter TTI mean that modulation needs to be kept low to maintain the same channel quality?

Good

Can u please me to understand the size of RB in diffrent numerology?

Can you please point to 5G layer 1 specification

what is 'mu' here?

Volume is too low, cant hear properly
