Ubiquitous space air ground integrated communication (USGIC) is emerging as a vital aspect of the sixth generation (6G) wireless communications. Due to the long transmission distance and complex communication environments, reliable communication become a challenging issue for 6G USGIC. Some new fundamental information theory and signal processing methods that can adaptively match the channel changes are needed. On the other hand, a comprehensive scope from the networking and the communication aspects are required. The goal of this workshop is to invite researchers from both academia, industry and other related areas to publish their latest efforts, to identify and discuss technical challenges, solutions of 6G-USGIC.Authors are invited to submit original and unpublished papers in any of, but not limited to, the following topics:

Information theory and performance analysis for 6G-USGIC

Fundamental information theory
Quantum information theory
Channel estimation and modeling
Space to ground signal propagation analysis

Signal processing technologies for 6G-USGIC

Quantum signal processing technologies
Orthogonal/non-orthogonal access technologies
Spatial, time, and spectrum diversity technologies
Source and channel coding technologies

Networking technologies for 6G-USGIC

Heterogeneous networks (HetNets) networking technologies
Queuing theory and optimization algorithms
Network protocol and routing technologies
Time sensitive networking technologies

Keynote 1: Low-Earth Orbit Satellite Constellations – A game-changer for global connectivity?

Björn Ottersten – Professor, University of Luxembourg

Abstract: The satellite communications sector is experiencing an unprecedented revolution pushed by the popularity of low-Earth orbit (LEO) satellite constellations for satellite Internet access. Satellite communication networks are evolving to become an integral part of terrestrial networks. With this integration comes the promise of wireless services to remote underserved areas and also backup connectivity in the presence of network failures or disaster events. We discuss broad trends that are changing the design of satellite communication networks fundamentally. Specifically, signal processing advances will be addressed with focus on multi-antenna transmit precoding techniques to improve coverage and spectral/energy efficiency, as well as link reliability and security. Recent advances validating these technologies over satellite and bringing them closer exploitation will also be presented.

He has received the IEEE Signal Processing Society Technical Achievement Award, the IEEE Communications Society Satellite Communications Distinguished Service Award, the EURASIP Group Technical Achievement Award, and is a two-time recipient of the European Research Council advanced research grant. His research interests include signal processing, wireless communications, and radar systems.

Keynote 2: From age of information to data importance and relevance

Nikolaos Pappas, Linköping University

Abstract: Wireless networks are evolving to cater to emerging cyber-physical and mission-critical interactive systems, such as swarm robotics, self-driving cars, and the intelligent Internet of Things. A fundamental shift in thinking is necessary to satisfy the requirements for real-time communication, autonomous decision-making, and efficient distributed processing. In this talk, we will focus on the freshness and value of information and present some initial results and ongoing works on semantics-aware goal-oriented communication. In addition, we will discuss potential research directions for satellite communication networks and how the incorporation of semantics can enhance their performance.

Bio: Nikolaos Pappas received the B.Sc. degree in computer science, the B.Sc. degree in mathematics, the M.Sc. degree in computer science, and the Ph.D. degree in computer science from the University of Crete, Greece, in 2005, 2012, 2007, and 2012, respectively. From 2005 to 2012, he was a Graduate Research Assistant with the Telecommunications and Networks Laboratory, Institute of Computer Science, FORTH, Heraklion, Greece, and a Visiting Scholar with the Institute of Systems Research, University of Maryland at College Park, College Park, MD, USA. From 2012 to 2014, he was a postdoctoral Researcher with the Department of Telecommunications, CentraleSupelec, Gif-sur-Yvette, France. He is currently an Associate Professor with the Department of Computer and Information Science, Linköping University, Linkoping, Sweden. His main research interests include the field of wireless communication networks with an emphasis on semantics-aware communications, energy harvesting networks, network-level cooperation, age of information, and stochastic geometry.
