Welcome to the GLOBECOM Workshop on
Wireless Communications for Distributed Intelligence
December 7-11, 2021 — Madrid, Spain
SCOPE AND TOPICS:
Sixth-generation (6G) mobile communications will feature emerging new PHY- and MAC-layer technology, especially ultra-large arrays, cell-free Massive MIMO, RadioWeaves, reconfigurable intelligent surfaces, TeraHertz, and machine-learning-optimized networking solutions. 6G will address connectivity scenarios that 5G never solved -- especially massive access with imperceptible latency and ultra-reliability. More significantly, it is envisioned that 6G will support entirely new use cases, including augmented/virtual reality, and providing a connectivity backbone for decentralized Artificial Intelligence (AI) applications, including distributed sensing, information processing, automatic controls, learning, and inference.
Due to the distributed nature of the data sets and computational units in wireless networks, state-of-the-art distributed intelligent (DI) services are heavily dependent on the underlying wireless communication protocols. The result is that current and upcoming wireless networks may be greatly stressed when trying to support state-of-the-art DI algorithms. Data or computation information for DI tasks such as distributed automatic controls, training, and inference, especially in a dynamic set-up where these computations have to be re-executed frequently, do not need to be transmitted according to the traditional wireless protocols built upon the principle of error-free communication. In such distributed systems, the communication design should be coupled with the eventual tasks performed by machines. This suggests that we need to reinvestigate fundamentally new wireless communication protocols (e.g., signal processing methods for physical layer and medium access controls) capable to achieve efficient and reliable DI task-oriented wireless connectivity.
The proposed workshop aims at covering both theoretical and practical perspectives of wireless communications for distributed intelligence in mobile networks, including network architecture design for AI-included 6G, emerging wireless technologies for data aggregation in distributed systems, and communication protocol design for large-scale ML, etc. We invite submissions of original and unpublished works on the related topics, which include but are not limited to the following:
