The SNS JU Working Groups (WGs) facilitate cross-project collaboration among representatives of ongoing SNS JU projects, aiming to create synergies and consolidate efforts. These groups regularly publish their findings in white papers and other forums. Projects can join an SNS JU WG by contacting the respective WG Chairperson. The WGs include the 6G Architecture WG, Reliable Software Network WG, Test, Measurement, and KPIs Validation WG, and Hardware Technologies WG. They serve as platforms for exchanging ideas, addressing technological challenges, and shaping a unified European perspective on 6G development.

Each WG focuses on specific domains. The Architecture WG consolidates architectural concepts for 6G, promoting discussions and dissemination of results. The Reliable Software Network WG addresses software networking trends, cloud-native designs, and AI/ML integration. The Test, Measurement, and Validation WG standardizes methodologies for KPI/KVI testing and lifecycle management, supporting 6G trials. Lastly, the Hardware Technologies WG explores advanced components, materials, and chipsets critical for 6G adoption, fostering collaboration across SNS and global initiatives to build a robust 6G hardware roadmap.
