论文摘要
我们讨论了如果要以自适应方式部署RISS在动态发展的丰富冰雪设置中，这是6G部署场景（例如工厂）的典型特征，则需要进行本地化，感应和通信的汇合。我们确定在此类问题中，通过RIS和不受控制的移动对象，丰富的无线通道会受到高度非线性的确定性双参数化。因此，通过本地化和感知获得完整的上下文意识是RIS授权通信的先决条件。然而，这种艰巨的通信开销的副产品可以养活许多需要上下文意识的设备，从而使高架关注可能消失。我们说明了基于原型案例研究的丰富散射下操作自适应RI的基本步骤。我们发现，自适应riss的表现优于上下文 - 仅低于某个噪声阈值，而这些噪声阈值取决于其他因素，其强烈不受控制的Perturbers影响了无线通道。我们还讨论了随后的未来研究方向，这些方向将确定RIS可以作为6G网络的技术推动力的条件。
We discuss the need for a confluence of localization, sensing and communications if RISs are to be deployed in a self-adaptive manner in the dynamically evolving rich-scattering settings that are typical for 6G deployment scenarios such as factories. We establish that in such problems the rich-scattering wireless channels are subject to a highly nonlinear deterministic double-parametrization through both the RIS and uncontrolled moving objects. Therefore, acquiring full context-awareness through localization and sensing is a prerequisite for RIS-empowered communications. Yet, the byproducts of this daunting communications overhead can feed many appliances that require context awareness, such that overhead concerns may vanish. We illustrate the essential steps for operating a self-adaptive RIS under rich scattering based on a prototypical case study. We discover that self-adaptive RISs outperform context-ignorant RISs only below a certain noise threshold that depends, among other factors, on how strongly uncontrolled perturbers impact the wireless channel. We also discuss ensuing future research directions that will determine the conditions under which RISs may serve as technological enabler of 6G networks.
