On Reducing EM Exposure to Large-scale BS Antenna Array Aided with CV in LOS Scenarios.

Without any radiation control measures, a large-scale mmWave antenna array at close range may lead to a large amount of electromagnetic exposure of human. In this paper, with the aid of pose detection in computer vision, an exposure avoidance method is introduced in outdoor line of sight scenarios, which controls radiation to vulnerable parts of human body and ensure communication quality in spatial dimension, instead of reducing transmitted power. And this paper applies a finer beam management granularity to better balance the trade-off between exposure reduction and communication quality loss. The simulation results show that the exposure avoidance method is effective, and the finer beam management granularity can guarantee communication quality while taking the exposure requirement for mmWave into account.
