摘要

我们研究了二进制（开/关）RIS元件的控制，以协助在室内环境中向移动用户传输。对于给定的用户位置，问题被提出为最大接收信号功率的问题。解决这个最大化问题的复杂性随着RIS元素的数量呈指数增长。为了获得实际可行的方法，我们考虑使用以下方法配置RIS状态：遗传算法、基于启发式的次优方法（本文的贡献）和随机配置。我们提供了基于分析和仿真的结果，证明了基于启发式的次优配置可以在显著降低复杂性的情况下获得接近最优的性能。这封信中提出的启发式方法提供了对系统底层结构的重要见解。

On the Control of Binary RIS Under User Mobility: Structural Results and Implications

We investigate the control of Binary (ON/OFF) RIS elements deployed to assist transmission towards a mobile user in an indoor environment. For a given user location, the problem is posed as that of maximizing the received signal power. The complexity of solving this maximization problem increases exponentially with number of RIS elements. In order to arrive at practically workable approaches, we consider configuring RIS states using: a genetic-algorithm, a heuristic-based sub-optimal approach (contribution of this letter), and random configuration. We provide analytical and simulation-based results, demonstrating that a sub-optimal heuristic-based configuration can achieve near-optimal performance with significantly lower complexity. The heuristic approach proposed in this letter provides significant insights into the underlying structure of the system.
