Accurate channel modeling and simulation are indispensable formillimeter-wave wideband communication systems that employelectrically-steerable and narrow beam antenna arrays. Three important channelmodeling components, spatial consistency, human blockage, and outdoor-to-indoorpenetration loss, were proposed in the 3rd Generation Partnership ProjectRelease 14 for mmWave communication system design. This paper presents NYUSIM2.0, an improved channel simulator which can simulate spatially consistentchannel realizations based on the existing drop-based channel simulator NYUSIM1.6.1. A geometry-based approach using multiple reflection surfaces is proposedto generate spatially correlated and time-variant channel coefficients. Usingresults from 73 GHz pedestrian measurements for human blockage, a four-stateMarkov model has been implemented in NYUSIM to simulate dynamic human blockageshadowing loss. To model the excess path loss due to penetration intobuildings, a parabolic model for outdoor-to-indoor penetration loss has beenadopted from the 5G Channel Modeling special interest group and implemented inNYUSIM 2.0. This paper demonstrates how these new modeling capabilitiesreproduce realistic data when implemented in Monte Carlo fashion using NYUSIM2.0, making it a valuable measurement-based channel simulator forfifth-generation and beyond mmWave communication system design and evaluation.
