The second plenary meeting of AROMA3D-Earth (NextGenerationEU [UNICO-5G I+D/AROMA3D-EARTH (TSI-063000-2021-69)) was held last Wednesday, October, 2nd, at the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC). The partners have the opportunity to discuss the latest advances in the consortium (CTTC, Celestia-TTI, Fivecomm) for:
* Exploring the wireless communications in the near-field (XL-MIMO) with multiple polarizations,
* Challenges to build antenna panels with 3 polarizations,
* Benefits of using machine learning (ML) :
- To adjust the power level in the UL of cell-free based system
- Beamforming design for rate splitting multiple access system
* Exploring possible protocols for IoT with the objective of coordinating the transmissions of different IoT devices for an efficient use of resources.
