Abstract-Millimeter wave (mmWave) communication is one of the technologies to meet the ever increasing demand of high quality entertainment services inside the passenger car. In accordance with the gigabit class backhaul technology for the high speed trains, the target is to achieve gigabit class link throughput at almost all (99%) the seats inside the passenger car of high speed trains (PCoHST). However 60GHz band mmWave communication suffers from huge human blockage besides severer

... n loss than the 2.4GHz band, hence the area of gigabit class link throughput that one mmWave AP (MAP) can support is smaller. We have shown that at least 4 MAPs are necessary to meet the above target. This paper proposes two topographic allocation types for the 4 MAPs taking into account of the physical structure of the PCoHST, the propagation characteristics and human blockage in the mmWave band. We evaluate the allocation types by ray tracing simulations under 4 typical human blockage scenarios with 3 typical occupancy rates. Simulation results show that the straight in-line allocation type on the ceiling at the center of the vehicular width is more feasible.
