The Hexa-X-II Project’s Work Package 4 (WP4) has released its latest deliverable, D4.3, which offers preliminary results on the 6G radio key enablers presented in D4.2. This deliverable provides a comprehensive overview of the holistic radio design framework, accompanied by technical studies and analysis of various enablers.
Holistic Radio Design Approach
The deliverable introduces a holistic design process that considers use cases and technical requirements and emphasizes key values for environmental, economical, and social sustainability. It covers a wide range of technical enablers across various radio design aspects, highlighting their role in balancing performance with value-based requirements. Additionally, D4.3 proposes a radio design framework for the selection and integration of these enablers, considering their dependencies and interactions to optimize the end-to-end radio system. This framework also provides interfaces to other components of the 6G system blueprint.
Spotlight on Key Enablers for Radio Design and Verification
This deliverable explores various enablers for architecture and transmission schemes across a broad spectrum range, including existing frequencies (sub-6 GHz, mmWave) and new spectrums (in cmWave frequencies, as well as (sub)-THz). It covers distributed MIMO, massive MIMO, multiuser MIMO, and reconfigurable intelligent surfaces (RIS)-assisted transmission, alongside advanced waveform and modulation schemes. The document presents solutions for spectrum access and sharing, with a focus on the integration of terrestrial and non-terrestrial networks (TN-NTN). It also introduces physical layer approaches to improve trustworthiness. Additionally, the deliverable emphasizes joint communication and sensing (JCAS) and intelligent air interface as pivotal innovations for 6G.
Initial Evaluation Results Towards Optimized 6G Radio System
This deliverable provides technical studies and presents intermediated results for the covered enablers by detailing their scope and methodology, and demonstrating initial simulation and/or experimental findings. The outcomes of these studies enhance the understanding of the potential roles of such enablers and their interactions withing the radio system. This comprehensive groundwork is essential for advancing into the selection and integration phase, which will be reported in D4.5. Moreover, the report outlines progress in developing supporting design and verification tools for channel modelling, particularly in unexplored (sub-)THz spectrums. It also describes simulation frameworks that accounts for multiple aspects, and proof-of-concept (PoC) platforms for assessment under realistic conditions.
