5G NR: 4G Vs 5G

I would suggest you to keep this diagram in your mind and dig further into the details for each item. It seems to me that most part (at least most part of Radio Access Protocol) overlaps with the current LTE and only small portions of new items are to be implemented. Red section part is new implemented in 5G and blue section part which is modified in 5G.
