Angular and Temporal Statistics for Millimeter Wave Channels

Millimetre wave (mmWave) is the key enabling
technology for next generation wireless communications. In order to
design and deploy 5G mmWave wireless communication systems
accurate channel models are of paramount importance. This paper
provides propagation statistics such as such as K-factor, root mean
square (RMS) delay spread, angular dispersion and number of
spatial clusters when omni and/or directional antennas are used at
the base and mobile stations using a 3D ray tracing simulator in an
urban environment. It compares the results for omni antennas with
the channel parameters proposed by the 3GPP (3rd Generation
Partnership Project) and mmMAGIC (mmWave based Mobile radio
Access network for fifth Generation Integrated Communications).
The results show that the small scale propagation parameters in the
3GPP are over predicted compared to our simulation results and the
mmMAGIC parameters. The results presented here provide useful
inside for the research and standardization process of future
mmWave systems.
