SCS 120 kHz
120 kHz Subcarrier Spacing (Numerology mu=3)
Millimeter-wave (FR2) numerology with 0.125 ms slot duration supporting up to 400 MHz bandwidth.
Technical Explanation
Numerology mu=3 features 120 kHz subcarrier spacing, providing 8 slots per 1 ms subframe (125 microsecond slot duration). It supports bandwidths up to 400 MHz (264 PRBs) in FR2 mmWave bands (24.25 - 52.6 GHz). Its wide subcarrier spacing provides robust resistance to severe high-frequency oscillator phase noise.
Key Functions
- Delivers ultra-fast 125 microsecond slot transmission times
- Supports extreme bandwidths up to 400 MHz per carrier
- Mitigates severe local oscillator phase noise in mmWave bands
