8th Training School

COST CA20120 – INTERACT 8th Training School: Decision Making Systems in Wireless Communications: from Theory to Practice

17-19 September 2025

Instituto de Telecomunicações and Escola Superior de Tecnologia e Gestão, Instituto Politécnico de Leiria, Portugal

Scope

Decision-Making via Lossy Wireless Communications assumes that observations from multiple terminals are sent to a fusion centre, where the original observations may not be losslessly constructed at the receiver side. This is particularly useful in IoT, Sensor Networks, and Cloud Radio Access Networks (C-RAN), where the goal is not to reproduce information losslessly but to make correct decisions based on the distorted data sequences collected.

The Summer School covers decision making through end-to-end lossy distributed wireless cooperative networks, distributed multi-sensor-based geolocation-and-tracking techniques, 5G private network for industrial applications, goal-oriented sensing and wireless networks, binary DHT using linear binary codes, integrated sensing and communications, drone/UAV applications, vehicle-to-everything communications, and practical sessions on cooperative, connected, and automated mobility.

This 18 hour training combines lectures, exercises, field tests, and practical computer-based sessions along with a social event.

Targeted Audience

The course is primarily targeted at PhD students but is open to researchers with an interest in these topics, from industry or academia.

The prerequisites are: basic knowledge of wireless communications, along with some knowledge of stochastic processes and appropriate engineering mathematics.

Supporting Texts

  • Prof. Tad Matsumoto will cover topics such as Decision-Making via End-to-End Lossy Wireless Communications Network. The broad aim is to combine knowledge from Network Information Theory and Distributed Hypothesis Testing for Decision Making as a Statistical Inference. Since in Beyond 5G and 6G wireless networks, the network throughput efficiency is expected to be very high, the covered topics will exploit the sources information correlation for the Decision-Making. The lecture includes the topics related to Decision Making via End-to-End Lossy Distributed Wireless Cooperative Networks: From Turbo Equalization to Distributed Hypothesis Testing, Machine Learning and Semantic Communications – with the special emphasis on how they are connected?  Age-of-Information (AoI) is also covered in the lecture, representing the average probability that the decision centre cannot make decisions due to the network delay.  The lecture will provide mathematical and information theoretic backgrounds, analytical methods, and numerical calculations for evaluating their performances.

Distributed Hypothesis Testing using Linear Binary Codes, by Ismaila Salihou Adamou, Telecom-Paris

In distributed hypothesis testing (DHT), the goal is to compress observed data so that a decision (e.g., classification or detection) can be reliably made at a remote decoder. This talk explores how DHT formalizes decision-making over coded data from an information-theoretic perspective. The first part of the lecture discusses the fundamental limits of DHT, including error exponents and rate constraints. The second part presents practical coding schemes based on linear block codes, demonstrating how short-length codes can be effectively used for decision tasks under communication constraints.

  • Doctor Ismaila SALIHOU ADAMOU is a postdoctoral fellow at Télécom Paris, within the Comunications and Electronics (COMELEC) Department. His research focuses on information theory, coding, goal-oriented communication, and the use of machine learning techniques for information-theoretic and coding problems. Prior to joining Télécom Paris, Dr. SALIHOU ADAMOU earned a Ph.D. in information theory, with an emphasis on practical short-length code design for goal-oriented tasks such as decision-making. He also holds an M.Sc. in Signal, Information, and Communication from Cergy Paris University, and a B.Sc. in Networks and Telecommunications from Djillali Liabès University. 
  • Doctor João Almeida will provide a conceptual talk on Vehicle-to-Everything (V2X) Communications for Maneuver Coordination of Autonomous Vehicles, and a Practical Session on Cooperative, Connected and Automated Mobility (CCAM) Applications. V2X communications enable Cooperative, Connected and Automated Vehicles (CCAVs) to achieve comprehensive environmental awareness and well-informed decision-making. This technological advancement is crucial for minimizing road accidents caused by poor perception or inadequate communication. With the growing importance of vehicle collaboration, new standardized messages and services for V2X communications have been introduced to enhance the coordination of CCAVs’ actions. This way, and together with the utilization of consensus algorithms and trust assessment mechanisms, CCAVs will be able to rely on each other for the execution of cooperative traffic maneuvers.

  • Title: Integrated Sensing and Communications: Signalling, Network Design and Security

     

    Abstract: The future global cellular infrastructure will underpin a variety of applications, such as smart city solutions, urban security, infrastructure monitoring, and smart mobility, among others. These emerging applications require new network functionalities that go beyond traditional communication. Key network KPIs for 6G include Gb/s data rates, cm-level localization, μs-level latency, and Tb/Joule energy efficiency. Additionally, future networks must support the UN’s Sustainable Development Goals to ensure sustainability, net-zero emissions, resilience, and inclusivity.

     

    The multifunctionality and net-zero emissions agenda call for a redesign of multi-access technologies for 6G and beyond. In this talk, I focus on enabling multifunctionality in signals and wireless transmissions as a means of reducing hardware redundancy and minimizing carbon footprint. We will explore the emerging field of integrated sensing and communications (ISAC), which represents a paradigm shift towards combining sensing and communication functionalities within a single transmission, utilizing a single spectrum and ultimately sharing a common infrastructure. In this talk I briefly present the opportunities of ISAC as a natural evolution of the two technologies, with obvious gains in energy-, hardware- and cost- efficiency through the use of dual-functional hardware. I further explain that their co-design also offers opportunities in flexible trade-offs and new synergies between sensing and communication. I then discuss unprecedented security vulnerabilities that ISAC brings about, that need to be urgently addressed before its large scale deployment. I present some results from my team’s work in the area, that underline the benefits of the co-design in offering a graceful trade-off between the communications, sensing and security, and some prototyping results. I conclude with some thoughts on research opportunities and the road ahead.
