Introduction Unlike 4G LTE, which relied on a fixed Subcarrier Spacing (SCS) and a static subframe duration, 5G New Radio (NR) introduces a flexible OFDM numerology frame structure scaling as Δf=15×2^μ kHz. Selecting the optimal numerology parameter (μ∈{0,1,2,3,4}) governs a direct trade-off between coverage geometry, PHY-layer latency, Doppler resilience, and hardware processing overhead. 1. Fundamentals of 5G Flexible Numerology 3GPP TS 38.211 specifies the mathematical f
