This paper presents 28 GHz and 73 GHz empirically-derived large-scale and\nsmall-scale channel model parameters that characterize average temporal and\nangular properties of multipaths. Omnidirectional azimuth scans at both the\ntransmitter and receiver used high gain directional antennas, from which global\n3GPP modeling parameters for the mean global azimuth and zenith spreads of\narrival were found to be 22 degrees and 6.2 degrees at 28 GHz, and 37.1 degrees\nand 3.8 degrees at 73 GHz, respectively, in non-line of sight (NLOS).\nSmall-scale spatial measurements at 28 GHz reveal a mean cross-polar ratio for\nindividual multipath components of 29.7 dB and 16.7 dB in line of sight and\nNLOS, respectively. Small-scale parameters extracted using the KPowerMeans\nalgorithm yielded on average 5.3 and 4.6 clusters at 28 GHz and 73 GHz,\nrespectively, in NLOS. The time cluster - spatial lobe (TCSL) modeling approach\nuses an alternative physically-based binning procedure and recreates 3GPP model\nparameters to generate channel impulse responses, as well as new parameters\nlike the RMS lobe angular spreads useful in quantifying millimeter-wave\ndirectionality. The TCSL algorithm faithfully reproduces first- and\nsecond-order statistics of measured millimeter-wave channels.\n
