Major Components of 5G Slicing

a) F-OFDM – Filtered OFDM – flexibly isolates the bands allowing different behaviors

b) Mixed Numerology – enable the different slicing features within RAN Slicing part

c) Slicing Breathe – Must be possible for slices to change size and to exchange physical resources
