Part II RAN Slicing and 5G Vertical Industries Multi-Numerology Waveform Parameter Assignment in 5G Ahmet Yazar1,* and Hüseyin Arslan 1 Electrical-Electronics Engineering, Istanbul Medipol University, Turkey 2Electrical Engineering, University of South Florida, USA Introduction Third Generation Partnership Project (3GPP) Release 15 for 5G new radio (NR) is devel- oped to meet the requirement diversity of different users and services [1]. Moreover, Release 16 and 17 are coming in two years respectively to meet further requirements of ultra-reliable low-latency communications (URLLC) and massive machine-type com- munications (mMTC) services [2]. Flexibility is increasing to be able to meet different requirements. The concept of multi-numerology is defined in 5G NR standardization to increase flexibility from the waveform perspective. Besides, scheduling and resource allocation become more related with waveform design thanks to the multi-numerology concept. However, frame flexibility brings more load at a scheduler [3]. There are more waveform parameter options that can be configured by the scheduler in NR compared to long-term evolution (LTE) [4]. Waveform parameter options can be analyzed with respect to the waveform components that include lattice, pulse shape, and frame [5].
