The infrastructures are divided between the North and South Node. There are also some themes that are relevant to both nodes, such as ArtificiaI intelligence. In addition, 6G-XR has identified some verticals that are considered complimentary to the internally developed Use Cases and can serve as examples of verticals that are welcome to this Open Call within the South Node:

• 6G-XR-OC3-TOP1.1: Full-fledged multimedia platforms / services providing new encoding and streaming solutions for Holographic Communications [Mentor: VICOM, i2CAT]
• 6G-XR-OC3-TOP1.2: Training and education, by using immersive platforms that support rich interaction and collaboration between distributed users [Mentor: i2CAT]
• 6G-XR-OC3-TOP1.3: Culture visits and events, by using immersive platforms that support real-time tele-portation to a virtual place or an event, and rich interaction therein. [Mentor: i2CAT]
• 6G-XR-OC3-TOP1.4: Smart Industry / Spaces, by using immersive platforms that support rich data sharing, manipulation of digital twins, and/or remote collaboration. [Mentor: i2CAT]
• 6G-XR-OC3-TOP1.5: Interactive multiuser multi-sensory experiences, by integrating multiple data modalities beyond audio and video. [Mentor: i2CAT]
• 6G-XR-OC3-TOP1.6: Energy immersive platforms for virtual testing and evaluation [Mentor: CGE]
• 6G-XR-OC3-TOP1.7: Cooperative, Connected and Automated Mobility (CCAM) in micro-mobility scenarios. [Mentor: i2CAT]

For the purpose of this 3rd Open Call, 6G-XR has identified some verticals that are considered complimentary to the internally developed Use Case 4: Collaborative 3D Digital Twin-like Environment within the North Node:

• 6G-XR-OC3-TOP2.1: Simulation and prediction; Prototyping simulation, Predictive maintenance in Industry. [Mentor: UOULU]
• 6G-XR-OC3-TOP2.2: Training and Education; Operational training, remote collaborative operations in education, medicals. [Mentor: UOULU]
• 6G-XR-OC3-TOP2.3: Visualization and data sharing; visualization of complex system and environment, real-time data dashboard in smart media, smart city, smart agriculture. [Mentor: UOULU]

For the purpose of this 3rd Open Call, 6G-XR has identified some verticals that are considered complimentary to the internally developed Use Case 5: Energy Measurement Framework for Energy Sustainability within the North Node:

• 6G-XR-OC3-TOP3.1: Utilization of open data in the optimization of RAN energy usage [Mentor: UOULU, VTT]
• 6G-XR-OC3-TOP3.2: End-to-end energy budgeting for the sustainable mobile network infrastructure [Mentor: UOULU, VTT]
• 6G-XR-OC3-TOP3.3: Visualization of mobile network measurement data [Mentor: UOULU, VTT]
• 6G-XR-OC3-TOP3.4: Calibrations, validations, and verification of energy measurement data [Mentor: VTT]

In addition to the previous complementary verticals directly related to the 5 internal Use Cases, 6G-XR has identified an cross-cutting theme that extends beyond the internally developed use cases: Artificial Intelligence. Applicants are welcome to submit proposals for both the South and North nodes.

• 6G-XR-OC3-TOP4.1: AI supervised manufacturing (UOULU Mentor UOULU, VTT, CGE, I2CAT)
• 6G-XR-OC3-TOP4.2: Distributed AI for Energy [Mentor: CGE]

However, this third and final Open Call welcomes any other vertical or different Use Cases under any other relevant vertical under the topic: 6G-XR-OC3-TOP5.1: Open vertical replicability [Mentor: Based on the selected infrastructure]

Please note that a minimum of one and a maximum of four proposals will be funded per infrastructure. The use of an alternative infrastructure may be negotiated if the chosen infrastructure is unavailable/unbalanced in terms of available resources.

A more detailed description of the topics can be found in the 6G-XR Open Call 3 Information Document.

Deadline dates:

• 10 January 2025 23:00 (Brussels time)
