Abstract
This talk gives brief overview of experiment-driven physical layer research for fifth-generation radio link designs. In particular, the talk highlights radio channel moiling at millimeter-wave frequency bands exemplified by our research results. One of the most important aspects of millimeter-wave channel modelling is frequency dependency of radio propagation and antennas. We clarify them from theoretical perspectives first, and then introduce a measurement-based study through radio channel sounding. The study reveals frequency dependency of critical radio channel properties, e.g., pathloss, human body blockage, delay and angular spreads of omni-directional channels, multipath sparsity and radio wave depolarisation. These findings partly support the recent development of the 3GPP channel model for new radios, while they may also suggest refinement of some other parts of the channel model. We also show that the findings have significant implications on attainable performance of radio links at millimetre-waves.
