T4: Data-Driven Modelling and Optimization of Green Future Mobile Networks: From Machine Learning to Generative AI

Sunday, May 5, 9:00-12:30
Room: To be announced
Speaker Name: Nicola Piovesan; Antonio De Domenico; David López-Pérez

Abstract:

The fifth generation (5G) of radio technology is revolutionizing our everyday lives, by enabling a high degree of automation, through its larger capacity, massive connectivity, and ultra-reliable low-latency communications. Moreover, 5G technology is allowing for the first time to expand cellular systems into new ecosystems, thus impacting every industry. Despite its unprecedented capabilities, however, 5G networks can —and must— further improve in certain key technology areas, such as that of energy efficiency. While current third generation partnership project (3GPP) new radio (NR) deployments provide an improved energy efficiency of around 4x w.r.t. 3GPP long term evolution (LTE) ones, they still consume up to 3x more energy. This is mostly due to the more processing required to handle the wider bandwidth and the more antennas, and is resulting in increased carbon emissions and electricity bills for operators. Even if the 3GPP NR specification provides a rich set of tools to meet IMT-2020 energy efficiency requirements, such as carrier, channel, and symbol shutdown, among others, it is important to note that one of the main energy consumption challenges of 5G networks is the complexity of their optimization in wide-area deployments: A large-scale, stochastic, non-convex and non-linear optimization problem. In light of the increasing interest in this field, this one-of-a-kind tutorial shares the author's industrial and academic views on this 5G energy efficiency problem. In more details, the tutorial provides a fresh look at energy efficiency enabling technologies in 3GPP NR, in particular, massive MIMO, carrier aggregation, the lean carrier design and different shutdown methods. By leveraging on the concepts of big data and machine learning, the tutorial presents practical scenarios in which data collected from thousands of base stations can be successfully used to derive accurate machine learning models for the main building blocks of the energy efficiency optimization problem. Furthermore, it explores the possibility of a future where generative AI plays a central role in autonomously generating explainable models, thus advancing the quest for energy-efficient networks. In this context, the tutorial delves into the adoption of large language models (LLMs) in the industry and the need for foundational telecom models and specific evaluation frameworks for generative AI.

T5: Bridging the Gap: Machine Learning and Wireless Innovation

Sunday, May 5, 9:00-12:30
Room: To be announced
Speaker Name: Hina Tabassum; Aryan Kaushik

Abstract:

The neXt generation (XG) of wireless networks is anticipated to be more complex and heterogeneous due to higher transmission frequencies, massive internet-of-things (IoT) devices in air-space-ground networks, and ultra-dense access points. Subsequently, the wireless channel coherence time is reducing, and faster online decision making is becoming critical than ever before. This tutorial will provide a holistic view of how artificial intelligence (AI) can support future wireless networks. In the first module, starting from the basics of deep unsupervised learning (DUL), we will present how DUL enables faster radio resource management (RRM) without high-quality training labels. Nevertheless, incorporating and satisfying convex/non-convex constraints with zero constraint violation is a fundamental challenge. Differentiable projection-based approaches will be discussed in this regard. The second part of the tutorial will focus on the applications of deep reinforcement learning (DRL) in vehicular networks and non-terrestrial networks (NTN). Vehicle-to-Infrastructure (V2I) communication is becoming critical for the enhanced reliability of autonomous vehicles (AVs). However, the uncertainties in the road-traffic and AVs' wireless connections can severely impair timely decision-making. It is thus critical to develop resilient and rapid decision-making algorithms to optimize the AVs' network selection and driving policies in order to minimize road collisions while maximizing the communication data rates. Thus, this tutorial will present a multi-objective DRL framework to characterize efficient network selection and autonomous driving policies. Finally, the tutorial will cover the applications of DRL in edge and cloud computing-based NTN-IoT networks and the use of AI solutions for energy efficient NTN-IoT. The tutorial will also touch upon the key usage scenarios in IMT-2030/6G framework and how intelligent multi-function approaches can be exploited to 6G networks. The tutorial will conclude by pointing out game-changing solutions such as generative AI and quantum-inspired AI solutions for further research.

T6: Semantic and Goal-Oriented Communications for Edge AI: Enabling Technologies and Challenges

Sunday, May 5, 14:00-17:30
Room: To be announced
Speaker Name: Emilio Calvanese Strinati; Mohamed Sana; Mattia Merluzzi

Abstract:

Today, as part of the race to 6G, Artificial Intelligence (AI), Machine Learning (ML), and wireless communications are converging into a unique system in which data are constantly collected, processed and exchanged among heterogeneous agents. The tremendous overhead and the need of computing resources makes it unfeasible to encode and transmit these data with classical approaches, while chasing challenging sustainability targets without degrading performance. This is due to energy, wireless capacity, and hardware constraints, whose limits are close to be achieved. The goal of this tutorial is to present the new paradigm of semantic and goal-oriented communications to enable edge AI and ML, with a wireless and computing perspective. Starting from the challenges of 6G in terms of use cases, key performance and value indicators, the tutorial will first focus on the communication perspective, with semantic extraction as a way of reducing communication overhead while correctly conveying desired messages and achieving target goals. Then, due to the involvement of computing resources in such future services, the focus will shift to goal-oriented connect-compute resource orchestration, to enable edge AI with target energy, latency, and accuracy. Overall, the tutorial brings together notions from communication theory, AI, ML and signal processing, to provide the learners with some of the useful tools to contribute to the emerging field of edge intelligence.

T8: Differentiable Ray Tracing for Radio Propagation Modeling

Sunday, May 5, 14:00-17:30
Room: To be announced
Speaker Name: Jakob Hoydis; Fayçal Ait Aoudia; Sebastian Cammerer

Abstract:

Digital Twin Networks (DTNs) are an emerging technology that will allow for the artificial intelligence (AI) and machine learning (ML)-based design, simulation, optimization, and control of 6G systems. Thanks to the recent progress of computer graphics, such as neural radiance fields (NeRFs), and other enabling technologies like LIDAR, scene geometries can be obtained with unprecedented accuracy in an automated fashion. However, the simulation of radio wave propagation via ray tracing does not only require accurate scene geometries but also the electromagnetic material properties of all scene objects. Obtaining the latter is a delicate task for which no mainstream solutions exist. In this tutorial, we will introduce a potential solution to this problem, called differentiable ray tracing for modeling of radio propagation, which is inspired by the recently developed inverse rendering techniques in computer graphics. The core idea is to treat the radio propagation simulation as a differentiable function with trainable parameters. This allows for gradient descent-based optimization of various parameters, ranging from permeability and conductivity over antenna and scattering patterns to the orientation and even position of objects. Apart from providing a solid theoretical introduction to (differentiable) ray tracing, we will explain different approaches to the creation of scenes and discuss several concrete applications of this novel technology which opens many exciting directions for future research. Of particular interest are learning-based approaches to aligning ray tracing algorithms and scene descriptions to measurements. All examples shown in the tutorial can be reproduced with the freely available open-source link-level simulator Sionna that is developed and maintained by the instructors.

T9: Generative and Discriminative AI Models for Physical Layer Communication Challenges

Sunday, May 5, 14:00-17:30
Room: To be announced
Speaker Name: Andrea M Tonello

Abstract:

Machine learning (ML) for communications is gaining significant interest although it is not fully clear whether ML can bring disruptive innovation and offer improved solutions w.r.t. to well established model-based approaches. This tutorial has three distinctive elements: firstly, it focuses on a timely topic, i.e., generative and discriminative AI and ML models for signal analysis (learning) and synthesis (generation); secondly, it highlights the pivotal role played by the estimation of the channel input/output mutual information; thirdly, it considers some relevant problems in physical layer communications: a) optimal detection/decoding, b) joint design of coding/decoding, c) channel capacity estimation in unknown channels). Finally, it illustrates neural architectures derived from a mathematical formulation of optimality criterions.

T10: Graph-Based Machine Learning for Wireless Communications

Sunday, May 5, 14:00-17:30
Room: To be announced
Speaker Name: Santiago Segarra; Ananthram Swami; Zhongyuan Zhao

Abstract:

As communication networks continue to grow in scale and complexity, traditional approaches to network design and operation are becoming inadequate. Machine learning (ML) has garnered significant attention in the communications and signal processing communities for its potential to complement conventional mathematical models in the capabilities of describing complex wireless systems and deriving computationally efficient solutions. However, standard ML methods, such as multi-layer perceptrons (MLPs) and convolutional neural networks (CNNs), struggle to effectively leverage the underlying topology of communication networks, causing significant performance degradation as network size increases. Graph neural networks (GNNs) emerge as a promising ML approach that has gained surging interest within the ML community. GNNs excel when dealing with large network scales and complex topologies, outperforming MLPs and CNNs in such scenarios. This timely tutorial provides a gentle introduction to GNNs and explores recent approaches for applying them to solve classical problems in wireless communications and networking, including power allocation, link scheduling, and routing. The emphasis will be on how GNNs can augment, rather than replace, existing solutions to these challenges. The goal of the tutorial is to foster further research and exchange between the communications and ML communities and to serve as a mechanism to get a larger number of researchers involved in this nascent area.
