  This paper investigates intra-cluster channel characteristics of non
line-of-sight (NLOS) 28 GHz channels in street canyon scenarios. These channel
characteristics include cluster numbers, number of subpaths within each
cluster, intra-cluster delay spreads, and intra-cluster angular spreads. Both
measurement and ray tracing results are presented and compared. Furthermore,
distribution fittings are performed and models and parameters for different
intra-cluster channel characteristics are proposed.
