SCS 15 kHz

Technical Explanation

Numerology mu=0 uses 15 kHz subcarrier spacing. Exactly 1 slot exists per 1 ms subframe, resulting in slot duration of 1.0 ms and maximum carrier bandwidth of 50 MHz (270 PRBs). It is predominantly deployed in low-band FDD spectrum (e.g. 600 MHz, 700 MHz, 800 MHz, 900 MHz, 1.8 GHz, 2.1 GHz) for wide-area coverage.

Key Functions

• Operates with 1.0 ms slot duration matching LTE subframes
• Maximizes coverage radius in low-band sub-1 GHz and sub-3 GHz spectrum
• Provides seamless coexistence with LTE via Dynamic Spectrum Sharing (DSS)
