摘要:

毫米波(mmWave)频带已经被用于第五代(5G)通信系统,并且毫无疑问将继续被部署用于超过5G(B5G)。然而,通过使用相同的信道探测器,在多频带和多场景下,特别是对于室外、多输入多输出(MIMO)和车辆到车辆(V2V)条件,未完全研究底层信道。在本文中,我们在28,32和39 GHz频段使用4*4天线进行多频多场景毫米波MIMO信道测量,用于三种情况,即,人体和车辆阻塞测量、室外路径损耗测量和V2V测量。深入研究了阻塞效应、路径损耗、覆盖范围、非平稳性和空间一致性等信道特性。提出了毫米波MIMO信道的阻塞模型、路径损耗模型和时变信道模型。信道测量和建模结果对于B5G室内热点、室外和车载网络场景中的进一步毫米波通信系统部署具有重要意义。

英文摘要:

Millimeter wave (mmWave) bands have been utilized for the fifth generation (5G) communication systems and will no doubt continue to be deployed for beyond 5G (B5G). However, the underlying channels are not fully investigated at multifrequency bands and in multi-scenarios by using the same channel sounder, especially for the outdoor, multiple-input multiple-output (MIMO), and vehicle-to-vehicle (V2V) conditions. In this paper, we conduct multi-frequency multi-scenario mmWave MIMO channel measurements with 4*4 antennas at 28, 32, and 39 GHz bands for three cases, i.e., the human body and vehicle blockage measurements, outdoor path loss measurements, and V2V measurements. The channel characteristics, including blockage effect, path loss and coverage range, and non-stationarity and spatial consistency, are thoroughly studied. The blockage model, path loss model, and time-varying channel model are proposed for mmWave MIMO channels. The channel measurement and modeling results will be of great importance for further mmWave communication system deployments in indoor hotspot, outdoor, and vehicular network scenarios for B5G.
