The terahertz band offering tens or even hundreds of gigahertz of consecutive bandwidth is nowadays considered as a major candidate for new radio access technology in 6G systems. By wisely utilizing this bandwidth one may not only provide extreme data rates at the access interface but enable principally new applications over-the-air such as Tactile Internet, holographic telepresence, and virtual reality. The aim of the project is to develop the set of fundamentally new models and algorithms to enable truly mobile ultra-broadband THz cellular radio access technology. These models will contribute to better understanding of THz specifics as well as requirements and constraints imposed at practical communications mechanisms and algorithms in THz systems. Thus, the successful completion of the project will make a decisive step closer to enabling principally new applications over the commercial systems.

Machine learning algorithms for energy efficient and QoS aware communications in heterogeneous 6G mmWave/sub-THz networks (ML6GThz)

The rollouts of millimeter wave (mmWave, 28-100 GHz) band 5G New Radio technology is hampered by highly unreliable connectivity and poor energy efficiency severely violating the IMT-2020 requirements. Even though 5G systems are not yet fully deployed, 3GPP already starts standardization of 6G systems operating in sub-THz band (100-300 GHz) that will be subject to similar effects. In EFFICIENT we will develop models, methods, and practical algorithms simultaneously improving the energy efficiency and user performance at the radio access level in 5G/6G networks operating in mmWave and sub-Thz frequency bands. The successful completion of the project will speed up the rollout of mmWave 5G NR systems as well as standardization of future mmWave/sub-THz 6G systems as well as improve durability, energy efficiency, and recyclability of user equipment by increasing the battery lifetime.

Wireless technology is commonplace in our daily life. Soon, it will become equally diffused in the fields of medicine and healthcare, where it aids people’s well-being and improves the quality of life. This project produces novel multimodal body-centric antenna systems that enable robust intra- and on-body communications and centralized wireless power transfer to multiple implanted devices simultaneously. Here, anatomically accurate models of the human body combined with modern electromagnetic field solvers will enable the judicious optimization of the system, considering the robustness of operation within the inherently variable and dynamic operating environment as its key characteristics. The centralized wireless powering enables miniature battery-free implantable devices that achieve the longevity of a lifetime, and through the multimodal operation, they also signal with other implants and wearable units wirelessly.

Multifunctional Radios in Radio-Frequency Systems’ Convergence (MULTIFUN)

Radio-frequency (RF) systems are converging in terms of spectrum allocations, equipment and waveforms toward united applications, in which each radio’s operation is defined by programming software and firmware only. To fully harness the benefits of this so-called ‘RF convergence’, the emerging general-purpose multifunctional radio devices need to be capable of in-band full-duplex (IBFD), i.e., same-frequency simultaneous transmit and receive (SF-STAR), operation. For instance, a united cellular base station and radar would be transmitting shared downlink communication and radar waveforms while simultaneously receiving signal reflections for sensing its surroundings. The research investigates how to achieve the IBFD/SF-STAR capability for multifunctional radios under self-interference and how to exploit them in new RF convergence applications, e.g., joint radar sensing and wireless communication at millimeter-wave frequencies.

Robust and Autonomous mmWave-based Drone Interworking and Aerial Networking Technology (RADIANT)

Wireless communications technology has become an important part of our life that prepares to support advanced applications and services with extremely massive and variable traffic. With such increasingly unpredictable and non-uniform loading, even the novel fifth-generation (5G) wireless technology may require more consistent coverage and on-demand capacity. In this research, we envision advanced 3D network architectures that integrate terrestrial and non-terrestrial deployments as well as employ connected swarms of unmanned aerial vehicles (UAVs), nicknamed drones. We specifically emphasize extremely high frequency (mmWave) radio communications capabilities and conduct a comprehensive performance characterization of dynamic 3D network layouts with multi-hop mmWave mesh and multi-connectivity features. This analysis is based on a novel space-time mathematical methodology, which will help understand the system-level performance, as well as yield optimized technology development choices.

Distributed AI for enhanced security in satellite-aided wireless navigation (RESILIENT)

The goal of this project is to develop tools for interference management in geolocation applications. The use of Global Navigation Satellite Systems (GNSS) is ubiquitous in civilian, security, and defense applications. As a consequence, the threat of a potential disruption, or even malicious superseding, of GNSS is real and can lead to catastrophic consequences. Therefore, there is a growing need for protecting GNSS against intentional and unintentional interference sources. Particularly, this project investigates a distributed framework to detect and classify threats using hybrid physics- and data-driven models, information which is then used to globally localize the sources of interference. This project is composed of a team of researchers from US and Finland, in a joint effort to advance worldwide security of GNSS against existing threats while providing an excellent opportunity for students to participate in an international project on cutting-edge technologies and methodology development. The team has planned workshops and activities in order to foster a fruitful collaboration between the international research team and students. This project considers problems related to distributed, collaborative learning tasks, where data-driven AI-models are leveraged to augment physics-based solutions for improved capabilities. The specific goals of the project are divided into three research goals. The first goal investigates the use of deep learning for detection/classification of interference and fusion of multiple correlated classifiers providing local threat detection probabilities. The second goal aims to localize and track the interference sources through the creation of global threat probability maps. This goal is achieved by advancing the field federated learning in a threefold way: (i) to efficiently digesting non-independent and identically distributed data; (ii) combining with active learning methods, whereby moving agents sample specific locations to improve estimation performance; and (iii) investigating federated meta-learning strategies that use task-level knowledge to improve global learning. The third goal of the project investigates the use of those global threat maps to mitigate their effects on collaborative receivers using robust factor graph optimization.
