Title: Mixed Waveform Numerology for Performance Enhancement in High Mobility Wireless Networks
Keywords: flexible numerology; high mobility; OFDM; physical layer; wireless networks

Abstract: In order to handle the ever-increasing requirements of mobile users, the design and operation of the physical layer of next-generation cellular networks demand high flexibility and efficiency. In addition, performance enhancement necessitates the support of a wide range of frequencies, intelligent dynamic use of the available spectrum resources, and the implementation of a number of types of waveform. Orthogonal Frequency Division Multiplexing (OFDM), and in particular its ability of Cyclic Prefix (CP) adaptation, appears unable to fulfil the requirements of the different types of services currently utilised by users. In this context, the parameters characterising the different types of waveforms, such as the number of subcarriers, subcarrier spacing (SCS) and slot duration, can be flexibly adapted to the current communication scenario, resulting in a reduction in latency and a significant improvement in user throughput. In this paper, the specific design peculiarities of mixed..
