AI 中文摘要
物联网（IoT）设备及应用的日益增多，导致传统基站（BS）网络中出现严重的接入拥塞。同时，物联网设备的低发射功率要求系统设计提供更大的分集增益。因此，低成本流量管理和信号增强机制变得至关重要。可重构智能表面（RISs）因其灵活性和高效性而日益重要。通过利用反射、折射和放大，RISs可作为创新中继节点，克服由阻塞造成的空间限制，并改善现有基础设施的覆盖范围。然而，RISs更广泛的应用仍有待探索。在本文中，我们提出在基站上部署共址RISs，并利用集成接入与中继（IAR）架构实现基站间的波域任务卸载，无需额外基础设施或产生额外解码延迟。考虑固定和动态子载波方案，我们展示了在无蜂窝网络和蜂窝网络中的性能提升。此外，我们研究了在无蜂窝和蜂窝网络中分配给每个物联网设备的RIS单元数量的影响。最后，我们讨论了IAR基站对未来通信设计带来的机遇与挑战。
英文摘要
The increasing number of Internet of Things (IoT) devices and applications leads to severe access congestion in conventional base station (BS) networks. Meanwhile, the low transmit power of IoT devices requires larger diversity gains from the system design. Therefore, low-cost traffic management and signal enhancement mechanisms become essential. Reconfigurable intelligent surfaces (RISs) are increasingly significant due to their flexibility and efficiency. Using reflection, refraction, and amplification, RISs can act as innovative relay nodes to overcome spatial limitations caused by blockages, and improve the coverage range of existing infrastructure. However, more extensive applications of RISs remain to be explored. In this paper, we propose to deploy co-sited RISs on BSs and use the integrated access and relay (IAR) architecture to enable wave-domain task-offloading between BSs, without requiring extra infrastructure or incurring extra decoding latency. Considering the fixed and dynamic sub-carrier schemes, we show the performance improvement in cell-free networks and cellular networks. In addition, we investigate the effect of RIS elements allocated to each IoT device in both cell-free and cellular networks. Finally, we discuss the opportunities and challenges of IAR BSs for future communications design.
