论文摘要

使用以上100 GHz无线电频率将是进一步增强第五代细胞的有前途方法之一。任何空气界面和蜂窝网络设计都需要通道模型,为此测量了大刻度参数(例如pathloss,延迟和角度扩散)的证据至关重要。本文提供了来自140 GHz频段的两个室内热点(INH)场景的准静态时空通道频道运动活动的证据。测量的两个INH站点是购物中心和机场登机厅。尽管假定的链路类型和射频频率范围差异,但我们估计的来自测量结果的OMNI大型参数与INH场景中新的无线电(NR)通道模型的第三代合作伙伴项目(3GPP)的大型参数非常匹配。 3GPP NR通道模型用于访问链接,据说有效期为100 GHz,而我们的测量值涵盖了140 GHz的Shortrange Backhaul方案。我们发现我们估计的大规模参数与机场3GPP NR频道模型的偏差要比购物中心中的偏差。

The use of above-100 GHz radio frequencies would be one of promising approaches to enhance the fifth-generation cellular further. Any air interface and cellular network designs require channel models, for which measured evidence of largescale parameters such as pathloss, delay and angular spreads, is crucial. This paper provides the evidence from quasi-static spatiotemporal channel sounding campaigns at two indoor hotspot (InH) scenarios at 140 GHz band, assuming short-range backhaul connectivity. The measured two InH sites are shopping mall and airport check-in hall. Our estimated omni-directional large-scale parameters from the measurements are found in good match with those of the Third Generation Partnership Project (3GPP) for new radios (NR) channel model in InH scenario, despite the difference of assumed link types and radio frequency range. The 3GPP NR channel model is meant for access links and said to be valid up to 100 GHz, while our measurements cover shortrange backhaul scenarios at 140 GHz. We found more deviation between our estimated large-scale parameters and those of the 3GPP NR channel model in the airport than in the shopping mall.
