AI总结:

该研究测量了室内热点环境下6.75GHz与16.95GHz中频频段的多径角扩展统计特性,对比3GPP模型验证了方位角扩展的一致性,发现天顶角扩展更小、多径丰富,为中频段MIMO波束成形部署提供支撑。

摘要:

我们针对工作在6–24 GHz低中频段与高中频段的下一代无线系统,给出了详细的多径传播空间统计结果。无线信道的大尺度空间特性包括发射端多径分量(MPC)的离开方位角扩展(ASD)、离开天顶角扩展(ZSD),以及接收端的到达方位角扩展(ASA)、到达天顶角扩展(ZSA)。我们将测量得到的角度统计量与行业标准3GPP模型进行对比,发现在6.75 GHz和16.95 GHz两个频点下,ASD与ASA的数值均与模型结果高度吻合。实测的视距(LOS)场景下ASD大于3GPP模型的ASD,表明方位面上的多径分量离开方向更加多样。观测到ZSA与ZSD均小于3GPP建模结果,原因是测量期间大部分多径的到达与离开都发生在天线视轴仰角方向。较大的角扩展说明6.75 GHz与16.95 GHz频段存在丰富的多径空间传播特性,为中频频谱中MIMO波束成形系统的部署提供了更良好的应用前景。

英文摘要:

We present detailed multipath propagation spatial statistics for next-generation wireless systems operating at lower and upper mid-band frequencies spanning 6--24 GHz. The large-scale spatial characteristics of the wireless channel include Azimuth angular Spread of Departure (ASD) and Zenith angular Spread of Departure (ZSD) of multipath components (MPC) from a transmitter and the Azimuth angular Spread of Arrival (ASA) and Zenith angular Spread of Arrival (ZSA) at a receiver. The angular statistics calculated from measurements were compared with industry-standard 3GPP models, and ASD and ASA values were found to be in close agreement at both 6.75 GHz and 16.95 GHz. Measured LOS ASD was found larger than 3GPP ASD indicating more diverse MPC departure directions in the azimuth. ZSA and ZSD were observed smaller than the 3GPP modeling results as most multipath arrivals and departures during measurements were recorded at the boresight antenna elevation. The wide angular spreads indicate a multipath-rich spatial propagation at 6.75 GHz and 16.95 GHz, showing greater promise for the implementation of MIMO beamforming systems in the mid-band spectrum.
