Welcome to IEEE WCNC 2024 Workshop on Modern Random Access for Massive Connectivity in 6G
The ability to provide connectivity to a massive number of low-power, low-complexity devices will play a pivotal role in the definition of next generation 6G systems, targeting a variety of diverse internet-of-things verticals enriched by the non-terrestrial segment. In this context, grant-free multiple-access protocols are a fundamental enabler in serving a dynamic population of devices that share the same communication medium to transmit in sporadic and unpredictable patterns. While traditional random-access protocols often treat collisions as wasteful, recent years have seen ground-breaking developments in the vision of beyond-5G and 6G communications. These new approaches, often categorized under the broad name of unsourced massive access, offer an entirely different perspective on grant-free protocols by constructively embracing interference, and have triggered a large amount of research in the past few years. Research in the field is further buttressed by clearly defined market-driven goals from the industry, in the quest for highly reliable, highly efficient, low-complexity access solutions for a massive number of devices. The road towards 6G and more generally IoT communications represent only some relevant application examples where upcoming research has the potential to leave a fundamental mark.
The goal of this workshop is to stimulate new contributions to the topic, with an emphasis on cross-layer interactions between the MAC and PHY layers of the protocol stack, as well as on the connections to coding theory. Additionally, we seek to explore the integration of machine learning techniques in the design and optimization of these protocols, unlocking innovative approaches to further enhance network efficiency and adaptability in the rapidly evolving landscape of 6G and IoT communications.
The workshop is supported by the 6G Research and Innovation Cluster (6G-RIC), an interdisciplinary collaboration linking a total of 32 research groups from 20 universities and research institutions supported by over 60 associate partners from science, industry and the public sector in Germany, designed to lay the scientific and technical foundations for the next generation of mobile communications.
