论文摘要
没有任何辐射控制措施，近距离的大型MMWave天线阵列可能会导致大量的电磁暴露。在本文中，借助计算机视觉中的姿势检测，在室外视线情景中提出了一种新型暴露避免方法的光束方案。所提出的方法可以通过偏离易受伤害的部位来保护人体脆弱部位免受电磁暴露的影响，而不是降低传播能力。此外，采用较细的光束管理粒度，以更好地平衡降低曝光和通信质量损失之间的权衡，因为较细的光束可以提供更多可调节性，以找到降低曝光而不会过多降低链路质量的光束。在模拟中验证了拟议的暴露方式，结果表明，较细的光束管理粒度可以保证沟通质量，同时减少电磁暴露。
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, a beamforming scheme using a novel exposure avoidance method is proposed in outdoor line of sight scenarios. Instead of reducing transmitted power, the proposed method can protect the vulnerable parts of human body from electromagnetic exposure during transmission by deviating the transmission beams from vulnerable parts. Besides, a finer beam management granularity is adopted to better balance the trade-off between exposure reduction and communication quality loss, because finer beams can provide more adjustability for finding the beam that reduces exposure without excessively reducing the link quality. The proposed exposure avoidance method is validated in simulations, and the results show that the finer beam management granularity can guarantee communication quality while reducing the electromagnetic exposure.
