标题： Beampattern-Based Tracking for Millimeter Wave Communication Systems

摘要： 我们提出了一种跟踪算法，用于在毫米波通信系统中维持基站（BS）与移动站（MS）之间的通信链路，其中天线阵列在BS和MS中都用于波束成形。考虑了下行链路传输，并且当MS相对于BS移动时，在MS上执行跟踪。 具体而言，我们考虑由于手部运动导致MS快速旋转的情况。 该算法通过利用波束的辐射模式随角度变化来估计到达角（AoA）。 数值结果表明，当MS以宽范围的角度速度旋转时，该算法能够实现准确的波束对准。例如，当每10毫秒可获得一次跟踪更新时，该算法可以支持高达每秒800度的角度速度。 显示英文摘要

摘要： We present a tracking algorithm to maintain the communication link between a base station (BS) and a mobile station (MS) in a millimeter wave (mmWave) communication system, where antenna arrays are used for beamforming in both the BS and MS. Downlink transmission is considered, and the tracking is performed at the MS as it moves relative to the BS. Specifically, we consider the case that the MS rotates quickly due to hand movement. The algorithm estimates the angle of arrival (AoA) by using variations in the radiation pattern of the beam as a function of this angle. Numerical results show that the algorithm achieves accurate beam alignment when the MS rotates in a wide range of angular speeds. For example, the algorithm can support angular speeds up to 800 degrees per second when tracking updates are available every 10 ms.
