For the baseline configuration with f_c = 2.4GHz, LEO altitude 600km, elevation angle 50° (like example), and static receiver, the computed satellite Doppler shift is approximately 35.56kHz. With the IEEE 802.11be subcarrier spacing of 78.125kHz, this corresponds to a normalized CFO of \epsilon \approx 0.455. Therefore, the Doppler shift is below one subcarrier spacing but still represents a significant fraction of the OFDM subcarrier spacing.
