The flexible mixed-numerology structure with orthogonal frequency division multiplexing (OFDM) waveform is a key enabler to meet the requirements of various applications in fifth-generation (5G) and beyond wireless networks. However, the high peak-to-average power ratio (PAPR) is still one of the main drawbacks and conventional numerology selection can only provide PAPR reduction for the time-domain numerology multiplexing. In this letter, a novel numerology scheduling (NS) method is proposed to provide PAPR reduction for both time-domain and frequency-domain numerology multiplexing scenarios. For the proposed method, the signal with minimum PAPR is selected from a set of signals with different NS. The simulation results and complexity analysis demonstrate that the proposed method with a linearithmic complexity improves PAPR reduction compared to conventional numerology selection.
