毫米波（mmWave）频段和其他6 GHz以上的高频已成为第五代蜂窝标准的核心组件，可提供高数据速率和超低延迟。这些乐队面临的一个关键挑战是来自障碍物的阻碍，包括人体。除了覆盖范围减小之外，阻塞还可能导致高度间歇性的链路，其中信号质量随着环境中障碍物的运动而显著变化。阻塞在整个协议栈中具有广泛的后果，包括波束跟踪、链路自适应、小区选择、切换和拥塞控制。因此，对这些阻塞动态进行准确建模对于开发和评估潜在的毫米波系统至关重要。在这项工作中，我们提出了一种新的空间动态信道探测系统的相控阵发射机和接收机工作在60 GHz的基础上。重要的是，该探测器可以高速快速测量多个方向，以提供复杂场景的详细空间动态测量。该系统是在一个室内家庭娱乐类型的设置与多个移动阻滞剂。初步结果分析这些数据与讨论的开放性问题，发展统计动态模型。
The millimeter-wave (mmWave) bands and other high frequencies above 6 GHz have emerged as a central component of fifth generation cellular standards to deliver high data rates and ultra-low latency. A key challenge in these bands is blockage from obstacles, including the human body. In addition to the reduced coverage, blockage can result in highly intermittent links where the signal quality varies significantly with motion of obstacles in the environment. The blockages have widespread consequences throughout the protocol stack including beam tracking, link adaptation, cell selection, handover, and congestion control. Accurately modeling these blockage dynamics is therefore critical for the development and evaluation of potential mmWave systems. In this work, we present a novel spatial dynamic channel sounding system based on phased array transmitters and receivers operating at 60 GHz. Importantly, the sounder can measure multiple directions rapidly at high speed to provide detailed spatial dynamic measurements of complex scenarios. The system is demonstrated in an indoor home entertainment type setting with multiple moving blockers. Preliminary results are presented on analyzing this data with a discussion of the open issues toward developing statistical dynamic models.
