The three EU funded project DESIRE6G, PREDICT6G, and DETERMINISTIC6G are developing new technologies to tackle determinism at a global scale in the yet to be defined 6G architecture. A joint workshop titled "Future deterministic programmable networks for 6G" is organized by these projects at the European Conference on Networks and Communications (EuCNC), 2023. EuCNC focuses on telecommunications aspects ranging from 5G deployment to 6G exploration and future communications systems and networks. The aim of this workshop is to open a space for discussion of the different approaches to determinism that these projects are choosing while discussing open points and possible collaboration topics. The workshop takes place on Tuesday, 6 June 2023, 14:00-17:30 where Dr. Afif Osseiran, vice-chair 5G-ACIA gives a Keynote on the “learnings on 5G for industries”. Members of the three projects will present key research topics being investigated under these projects. A panel discussion will wrap up the workshop enlightening how the future deterministic 6G networks will be realized.
