Reliability enhancement in multi-numerology-based 5G new radio using INI-aware scheduling
Abstract Multi-numerology waveform-based 5G new radio (NR) systems offer great flexibility for different requirements of users and services. However, there is a new type of problem that is defined as inter-numerology interference (INI) between multiple numerologies. This paper proposes novel schedul...
