3. Frequency organization of the radio interface
The main novelty of NR technology lies in the greater flexibility of subcarrier spacing, as well as the possibility of using frequencies above 6 GHz and integrating antenna arrays more easily than with 4G-LTE.
3.1 Notion of numerology
One of the characteristics of OFDM is that the modulation width is identical to the frequency spacing between 2 successive subcarriers, denoted by Δf
