Abstract / truncated to 115 words (read the full abstract)

In order to meet the diverse requirements imposed by a massive number of applications, the fifth generation (5G) New Radio (NR) Physical Layer (PHY) is designed to provide a highly flexible framework. This flexibility is made possible through a scalable numerology. The term numerology refers to the PHY waveform parametrization and allows the use of different subcarrier spacings, symbol and slot durations. In addition to an efficient support of various service requirements, employing a scalable numerology allows a better adjustment of the PHY waveform to different channel conditions, providing more robustness against channel variations. Despite increased flexibility provided by multiplexing different numerologies, there is also a drawback of this concept, i.e., Internumerology Interference (INI) caused ... toggle 3 keywords
