摘要:

列车乘客数量以及对处理视频流和物联网技术等新技术所需的高数据速率需求持续增长。因此,探索毫米波(mmWave)频段是满足这一需求的关键技术。然而,高穿透损耗使毫米波对遮挡非常敏感,限制了其覆盖范围。一种有前景、高效且低成本的解决方案是可重构智能表面(RIS)。本文综述了毫米波背景下用于铁路通信的RIS研究现状。首先,我们介绍了不同类型的RIS,并回顾了文献中用于求解RIS相移的一些优化算法。然后,我们回顾了铁路领域RIS的最新研究,并给出了未来研究方向。

英文摘要:

The number of train passengers and the demand for high data rates to handle new technologies such as video streaming and IoT technologies are continuously increasing. Therefore the exploration of millimeter waves (mmWave) band is a key technology to meet this demand. However, the high penetration loss makes mmWave very sensitive to blocking, limiting its coverage area. One promising, efficient, and low-cost solution is the reconfigurable intelligent surface (RIS). This paper reviews the state of the art of RIS for railway communications in the mmWave context. First, we present the different types of RIS and review some optimization algorithms used in the literature to find the RIS phase shift. Then, we review recent works on RIS in the railway domain and provide future directions.
