Ericsson has joined forces with KTH Royal Institute of Technology in Sweden and eight other partners to solve one of the key challenges of new 6G networks, predictable end-to-end connections between users, processes, and digital representations in the cyber world.
While 5G networks are currently being rolled out commercially, researchers are working on the next generation of mobile networks, commonly referred to as “6G.” DETERMINISTIC6G, a 5.7 million euro research and innovation consortium coordinated by Ericsson and KTH, has been launched in January 2023 to ensure networks can accommodate new applications within industrial automation, manufacturing, transport, medicine, and entertainment.
Central to the project is the concept of deterministic communication, which has the property of guaranteeing communication latency and reliability. In total, the consortium consists of ten partners that combine mobile network leadership (Ericsson, Orange) with visionary applications and vertical ecosystem insights (B&R, IUVO, and SSSA), paired with leading research institutes (KTH, University of Stuttgart, and Silicon Austria Labs) and two highly innovative SMEs (Cumucore and Montimage).
Making sure end-to-end communication is sufficiently reliable remains a challenge for cellular networks in an industrial context. The new project will develop the technology enablers that are essential for building the so-called time-sensitive communication technology needed for 6G. This will ensure that it can be used in the most advanced ways possible, such as industrial automation.
Magnus Frodigh, vice president and head of research at Ericsson Research, says: “I have high expectations for DETERMINISTIC6G, a 6G technology enabler project focused on deterministic communication. “With a unique consortium combining expertise from both the wired and wireless domains, DETERMINISTIC6G has the potential to shape the foundations of 6G systems with respect to time-critical applications.”
James Gross, a professor with the Electrical Engineering and Computer Science School at KTH and the project’s technical manager, adds: “This project can shape the technological foundations of future 6G systems.”
A central focus of the project will be the interplay between future 6G networks and highly time-synchronized networks called Time Sensitive Networking (TSN). The challenge in these settings is that wireless systems like 6G can be subject to strong random variations, which are incompatible with technologies like TSN. How to overcome these challenges is an open research problem. DETERMINISTIC6G will tackle this problem through a combination of new wireless transmission design and advanced machine learning algorithms, leading to 6G wireless transmission with deterministic latency behavior.
In addition to this, the project will also consider consequences and novel approaches for time synchronization, network security, and the integration of computational nodes into 6G systems. A final point on the research agenda is how to make future networks aware of subsequent, upcoming changes that are important for the running of applications. Networks like 6G will have additional means to acquire fine-grained information about such changes in comparison to the networks of today.
Altogether, these developments will lay the foundation of the 6G vision to cater for stringent application requirements needed to work under complex scenarios.
