Multi-RATs (Radio Access Technologies): NR (New Radio) and evolved LTE (Long Term Evolution) will together constitute 5G. Utilizing NR at high frequencies will have a significant impact on radio propagation conditions. This paper sheds light on how to integrate NR into a single 5G framework and explores which protocol stack layer could be used as aggregation layer.
