TL;DR: In this article, the authors give four 5G mmWave deployment examples and describe in chronological order the scenarios and use cases of their probable deployment, including expected system architectures and hardware prototypes.
Journal ArticleDOI
Channel Measurement, Simulation, and Analysis for High-Speed Railway Communications in 5G Millimeter-Wave Band
TL;DR: Channel characteristics are studied in the 5G mmWave band for typical HSR scenarios, including urban, rural, and tunnel, with straight and curved route shapes, and Suggestions on symbol rate, sub-frame bandwidth, and polarization configuration are provided to guide the 5 G mmWave communication system design in typical H SR scenarios.
Proceedings ArticleDOI
Distributed antenna system-based millimeter-wave mobile broadband communication system for high speed trains
Junhyeong Kim,Il Gyu Kim +1 more
TL;DR: Throughout the paper, the feasibility of the system with moderate implementation complexity is shown, and the simulation results also demonstrate that it is possible to provide gigabit-per-second data services for HSTs.
Journal ArticleDOI
A Geometry-Based Stochastic Channel Model for the Millimeter-Wave Band in a 3GPP High-Speed Train Scenario
TL;DR: A geometry-based stochastic channel model (GSCM) for a 3GPP millimeter-wave (mmWave) high-speed train (HST) scenario and its implementation for channel simulation, which is useful for generating an integral and accurate channel geometry.
