The OFDM waveform’s subcarrier spacing (SCS), defined in the LTE standard, is fixed at 15 kHz. To better meet the needs of diversified services, NR supports multiple SCSs. The SCS is extended by the integer power of 2 based on 15 KHz, which includes the values of 15 kHz/30 kHz/60 kHz/120 kHz/240 kHz. With the increase of SCS, the corresponding OFDM symbol length is also shortened proportionally. Due to the use of flexible SCS, it can adapt to different service requirements.
