Sensing is envisioned as an indispensable part to construct an intelligent in-building environment. Compared to well-developed wireless communications, radio/radar sensing is still in its infancy for indoor networks. As 5G and beyond wireless networks will be ubiquitous indoors, it is particularly attractive to realise extra sensing capability that is piggybacked on indoor wireless networks.Recent developments in dual-functional radar-communication (DFRC) systems represent an excellent opportunity to integrate wireless communications and radar sensing indoors. For an indoor DFRC system, its communication and sensing (C&S) performance largely depends on the DFRC transceiver and the radio environment. Even though major efforts have been made on designing DFRC transceivers, radio environments as another key element to realise the potential of DFRC for integrated C&S remain unexplored. To realise the potential of DFRC systems for integrated C&S, the CIRED project will: 1) Define a set of metrics to measure the C&S performance of indoor radio environments; 2) Establish mathematical models to characterise the impact of indoor radio environments on DFRC systems; and 3) Develop advanced algorithms to optimally customise indoor radio environments for C&S. The achievement of these objectives will significantly enhance the C&S performance of indoor DFRC systems. The project is timely as integrated sensing and communication (ISAC) is critical for 6G networks.

传感被认为是构建智能建筑环境不可或缺的一部分。与成熟的无线通信相比，室内网络的无线电/雷达传感仍处于起步阶段。由于 5G 及更高版本的无线网络将在室内无处不在，因此实现基于室内无线网络的额外传感能力特别有吸引力。双功能雷达通信 (DFRC) 系统的最新发展代表了在室内集成无线通信和雷达传感的绝佳机会。对于室内 DFRC 系统，其通信和传感（C&S）性能很大程度上取决于 DFRC 收发器和无线电环境。尽管在设计 DFRC 收发器方面做出了重大努力，但作为实现 DFRC 集成 C&S 潜力的另一个关键要素的无线电环境仍未得到探索。为了实现 DFRC 系统在集成 C&S 方面的潜力，CIRED 项目将： 1) 定义一组指标来衡量室内无线电环境的 C&S 性能； 2）建立数学模型来表征室内无线电环境对DFRC系统的影响； 3) 开发先进算法，为 C&S 优化定制室内无线电环境。这些目标的实现将显着提高室内 DFRC 系统的 C&S 性能。该项目非常及时，因为集成传感和通信 (ISAC) 对于 6G 网络至关重要。
