— Check our recent work on "Outdoor Urban Millimeter Wave 3D Beam Alignment Using 3D Ray Tracing" 2016:
     (a) Video A (Setting): Showing the UE's movement and rotation, antenna arrays at both UE and BS, six-sector BS configuration, and the street geometry.
     (b) Video B (Multicell & Single-UE): Showing the beam-alignment and UE re-attaches to another BS when the original link is blocked. The frame duration is 10ms. The red line is the desired channel path.
     (c) Video C (Multicell & MultiUE): Showing the intra-cell interference management. The green line is the downlink interference channel path.
     (d) Video D (Holistic View): Showing more UEs runing in the simulator.
