Project title: 6G Integrated Communication & Sensing for Mobility - ICAS4Mobility
Project period: October 2022 - September 2025
More about ICAS4Mobility
Communication and radar systems are still operated separately today, even though they have many things in common from a technical point of view, e.g., in terms of signal processing and system architecture. This separation leads to inefficient use of the radio spectrum and to suboptimal overall solutions.
The goal of 6G-ICAS4Mobility is to more closely couple and integrate previously separate communication and sensing functionalities (esp. radar) in the course of developments towards 6G. The focus is on mobile applications in the context of automotive and aerial drones, as well as on the terminal side with direct communication ("sidelink") between the devices involved. Different levels of integration will be considered and evaluated, ranging from using communication capabilities to coordinate different radars to deep integration using a single waveform. Coordination of sensing functionalities across different devices (e.g., vehicles, drones) combined with high-accuracy time synchronization can also realize bi- or multistatic radars, which can increase efficiency and significantly improve environmental sensing. Furthermore, a distributed fusion of the environment images generated by different participants (as a kind of digital twin of the environment) will be realized in order to accurately and efficiently capture even complex scenarios. In addition to numerous conceptual tasks, four concrete scenarios (including extensive radio channel measurements) will be implemented and comprehensively evaluated in the sense of a proof-of-concept.

Project title: Perceptive communication networks with integrated sensing for the 6th generation of mobile communications - Komsens-6G
Project period: November 2022 – November 2025
More about KOMSENS-6G
The goal of KOMSENS-6G is to add another core functionality to the 6th generation mobile radio system: radio sensing. Sensing the environment using mobile radio signals is essential and useful for future mobile radio systems both in public spaces and in the context of campus networks. New use cases in areas such as industrial production (e.g. digital twin) and mobility (e.g. traffic monitoring) will be enabled. In addition, this can be used to better optimize the communication interface. To achieve this goal, all relevant components of the mobile radio system are analyzed and adapted accordingly, so that the sensing functionality itself is part of the overall system, i.e. a deep integration of sensing into the mobile radio system is aimed at, in contrast to other approaches where the sensing functionality is realized by separate systems (such as automotive radar) and the mobile radio system is only used as a means for data communication between the external sensors.
To integrate sensing into 6G systems, cellular systems need to be enhanced in two directions: The first is the further development of mobile radio systems in terms of their ability to distribute information between two or more points efficiently and according to certain specifications. The second, at least equally important functionality - and core element of this project outline - is the ability to digitally capture the above-mentioned physical systems with respect to their properties in real time. As an example, the presence, position, orientation and motion vector of a drone in the observed airspace or of a robot in a production environment. In addition to the implementation of the use cases mentioned above, the digital capture of the environment also gives the mobile system the opportunity to improve its own performance.
AI-based simulation and emulation methods to develop a virtual or digital twin that mirrors the real radio environment and reduces complexity to a necessary level. In addition to the AI approach, this requires the further development of simulation and emulation methods. The application area focuses on automated and connected driving.

Project title: DFG 4 CAD
Project period: April 2022 – April 2025
Testing a variety of traffic scenarios and radio network configurations plays an important role in ensuring the safety and reliability of automated driving. The goal of this project package is to improve the verification and validation of radio technologies to ensure the safety of road users even at higher levels of automation. The package consists of two projects:
One of the projects will adapt current over-the-air (OTA) V2X testing to future test requirements and aims to couple a system-level simulator in vehicular ad hoc networks with an OTA test facility. Particular attention will be paid to modeling and emulating the radio channel under the typical dynamic changes in channel conditions that result from the traffic events that govern the simulations.
Project 2 will investigate how virtual verification and validation (VVV) of automotive radars can be performed in a way that increases the reliability of environment perception. Likewise, metrics and quality factors for radar-based automated driving are identified and multi-stage VV chains are implemented, ranging from SiL to vehicle-in-the-loop (ViL) to test routes.
Project title: High-resolution parameter estimation for millimeter wave propagation in dynamic scenarios - HoPaDyn
Project period: August 2019 - April 2024
Future 5th generation mobile communications systems will use frequencies in the millimeter wave range with bandwidths of several GHz. For reasons of link budget, very large ("massive") antenna arrays will be required. These inevitably have high directivity, and the radiation patterns must be adaptively tracked. To date, no channel models exist for predicting and evaluating the performance of such systems. The aim of this project is the development of a high-resolution parameter estimator based on the maximum- likelihood principle, which solves this task in connection with an antenna array whose architecture is adapted to it. The data model of the parameter estimator must take into account that directions, travel time and Doppler are no longer available in a factorizable form. factorizable form. This overcomes the usual narrowband assumption and requires a consistent description of the array in the time domain, which is accompanied by new design paradigms for the antenna elements and their arrangement in terms of diameter and antenna spacing. In order to meet the special challenges of highly time-varying scenarios, path tracking by Bayesian filters will be applied in the estimation. For this purpose, methods of multi-target tracking in radar will be used, which will be adapted for the estimation task at hand. As a result, advantages are expected, such as a reduced computational effort, a higher accuracy or resolution, and the clarification of ambiguities that may arise, among others, due to the special array design.

Project period: 2014 - 2017
More about Medici Polaris
Due to decades of guerrilla warfare in Colombia, the country is littered with landmines. The project aims to support mine clearance.
The main objective of MEDICI-POLARIS is to investigate a method, which is able to improve the signal-to-clutter ratio (SCR) for GPR operation. In order to increase the SCR, and to eliminate the overlaying surface reflection, an adaptive radar system, which performs an automatic re-arrangement of the wave radiation direction to an optimal incident angle, is investigated. Since the knowledge of the effective soil permittivity is inevitable, contact free soil permittivity estimation methods will be also investigated. This project is supported by the DFG and Colciencias.

Project title: Cooperative perception and situation recognition in mobility and logistics using passive radar - KoSiMolo
Project period: 2017 - 2019
The public mobile communications networks of the 5th generation (5G) will play a key role in the digitization of data processes in mobility and logistics as well as for future intelligent transportation systems. The course for this is currently being set at full speed in international standardization bodies. While previous mobile networks (GSM, UMTS, LTE) were trimmed to maximum capacity and data rate for fast Internet access, one of the most serious innovations (perhaps even the most decisive) of 5G will be the introduction of data services that allow real-time control and regulation of a wide range of processes in industry, traffic and daily life. This will shift the focus of network use away from simple end-to-end communication or data transfer to cooperation between participants. The interdisciplinary KoSiMolo research group is dedicated to this topic and is thus making a significant contribution to the development of innovative technologies for the key objective of "sustainable and intelligent mobility and logistics" in Thuringia.

Project title: Huawei Thz
Project period: January 2022 - December 2024
The aim of the project is to carry out channel measurements for the characterization of near- and mid-range mobile wireless communication channels in the sub-THz frequency range (100 – 300 GHz), with a special focus on industrial and commercial scenarios. Since future mobile communication systems will profit from the presence of multiple available frequency bands (sub-6, millimeter-wave, and sub-THz), multi-band measurements will be performed, which is an essential step for evaluating of prospective use cases.
For the envisaged coexistence of sensing and communications in future mobile communication systems, an additional focus for possible future concurrent sensing applications (e.g. indoor localization) will be considered for the planning of the proposed measurement campaigns. For this, basic investigations of possible propagation measurement techniques which can be used for channel modeling for concurrent communication and sensing applications, will be undertaken and implemented in the measurements.
