地理围栏是指在网络边界内控制无线服务的可用性。本文研究了如何在室外到室内的网络场景中利用RIS实现地理围栏。具体而言，我们提出了GeoRIS，一种RIS控制器，通过利用波束管理程序来控制具有可操纵定向传输链路的网络中的波束对齐，从而实现地理围栏。GeoRIS不需要控制室外基站，并且可以在有无信道状态信息的情况下工作。通过基于3GPP网络模型的仿真，我们验证了GeoRIS，并证明它可以“屏蔽”室内网络区域（例如，通过削弱通信链路，使室内用户无法满足5G eMBB服务的最低要求）。我们还强调了一个有趣的见解：同一个RIS可以扮演双重角色，即扩展或抑制室外到室内的通信。在我们的仿真中，我们展示了GeoRIS可以轻松地将室内空间从“强覆盖区域”（例如，在大约90%的网络区域支持eMBB服务）转变为“服务中断区域”（例如，在大约90%的网络区域抑制eMBB服务），反之亦然，这在需要动态室内覆盖控制的场景中是一个有吸引力的特性。
英文摘要
Geofencing refers to controlling the availability of wireless services within a network perimeter. In this paper, we study how RIS can be used to achieve geofencing in outdoor-to-indoor network scenarios. Particularly, we propose GeoRIS, a RIS controller that achieves geofencing by exploiting beam management procedures to control beam alignment in networks with steerable directional transmission links. GeoRIS does not require control over the outdoor base station and can work with or without channel state information. Through simulations based on 3GPP network models, we validate GeoRIS and demonstrate that it can "shield" an indoor network area (for example, by weakening communication links to the point where indoor users cannot meet the minimum requirements of 5G eMBB services). We also highlight an interesting insight: the same RIS can play a dual role, extending or inhibiting outdoor-to-indoor communication. In our simulations, we show that GeoRIS can easily change an indoor space from a "strongly covered area" (e.g., supports eMBB services in approx. 90% of network area) to an "out-of-service area" (e.g., inhibits eMBB services in approx. 90% of network area), or vice-versa, an attractive characteristic in scenarios in which dynamic indoor coverage control is needed.
