Abstract
In this paper, the radio parameters are designed for OFDM-based millimeter-wave (mmWave) communication systems. Firstly, design principles are presented to meet 5G requirements. Secondly, the radio parameters including TTI length, CP length and sub-carrier spacing for mmWave bands are discussed. In particular the impact of phase noise on subcarrier spacing is analyzed in detail. It shows that the phase noise dominates the sub-carrier spacing design. Based on the measured phase noise model, minimum sub-carrier spacing of 250 kHz and 500 kHz is inferred for typical mmWave bands (30 GHz and 70 GHz). At last a numerology with 600 kHz sub-carrier spacing and 512 OFDM symbols per subframe (1 millisecond) is proposed as a unified one for all mmWave bands, which can satisfy the design principles of mmWave systems.
