The deployment of millimeter-wave (mmWave) cellular systems in dense urban environments with an acceptable coverage and cost-efficient transmission scheme is essential for the rollout of fifth-generation and beyond technology. In this paper
cluster-based analysis of mmWave channel characteristics in two typical dense urban environments is performed. First
radio propagation measurement campaigns are conducted in two identified mmWave bands of 28 and 39 GHz in a central business district and a dense residential area. The custom-designed channel sounder supports high-efficiency directional scanning sounding
which helps collect sufficient data for statistical channel modeling. Next
using an improved auto-clustering algorithm
multipath clusters and their scattering sources are identified. An appropriate measure for inter- and intra-cluster characteristics is provided
which includes the cluster number
the Ricean
K
-factor
root-mean-squared (RMS) delay spread
RMS angular spread
and their correlations. Comparisons of these parameters across two mmWave bands for both line-of-sight (LoS) and non-light-of-sight (NLoS) links are given. To shed light on the blockage effects
detailed analysis of the propagation mechanisms corresponding to each NLoS cluster is provided
including reflection from exterior walls and diffraction over building corners and rooftops. Finally
the results show that the cluster-based analysis takes full advantage of mmWave beamspace channel characteristics and has further implications for the design and deployment of mmWave wireless networks.
