“The 6G Architecture Landscape – European perspective” – by Bahare, Massod Khorsandi; Gavras, Anastasius; Gramaglia, Marco; Cosmas, John; Li, Xi; Bulakci, Ömer; Rahman, Arifur; Kostopoulos, Alexandros; Mesodiakaki, Agapi; Tsolkas, Dimitris; Ericson, Mårten; Boldi, Mauro; Uusitalo, Mikko; Ghoraishi, Mir; Rugeland, Patrik
This white paper summarizes the main findings from the European research landscape on the vision of the 6G architecture. Such a design vision is derived from around 45 projects starting from October 2020 in all relevant areas of 5G while paving the way towards 6G, within the 5G Public Private-Partnership (5G PPP) in the scope of the European Framework for Research and Innovation (the list of contributing projects can be obtained from the 5G PPP website.). At present, the European networking research community has started a new program along with 33 projects on the Smart Networks and Service (SNS) programme that will focus on 5G advanced and 6G. The 5G/B5G Architecture Working Group (WG), as part of the 5G PPP Initiative, is identifying and capturing novel trends and key technological enablers for the realization of the 5G and 6G architecture. The main findings and results of the Architecture WG are now captured in this white paper, which presents a consolidated view from European perspective on the technical directions for the architecture design in the 6G era.

D1.1 “Use case-driven specifications and technical requirements and initial channel model”
D1.1 provides an inventory of interactive use case specifications, representative deployment scenarios, technical requirements and KPIs for the four focus domains. D1.1 includes the initial channel model based on existing measurements and models. It reports on the particular investigation of the origin of latency in wireless applications.
D2.1 “Initial assessment of architectures and hardware resources for a RadioWeaves infrastructure”
D2.1 provides an initial assessment of the RadioWeaves infrastructure, developed in WP2 of REINDEER. Taking the description of RadioWeaves in D1.1 and the use cases and KPIs defined therein, as a starting point, a first version of the building blocks of the infrastructure are presented, together with new terminology. Architecture and topology are introduced together with a quantitative and qualitative analysis of high-level requirements on a RadioWeaves infrastructure, setting the scope for more detailed investigations and design.
D3.1 “Analytical Performance Metrics and Physical-Layer Solutions”
D3.1 develops a framework for physical-layer performance evaluation of RadioWeaves. Specifically, an effective-SINR abstraction model is developed and shown to be accurate and highly efficient in terms of computational complexity. Furthermore, this document evaluates complexity of existing algorithms in terms of computational load and front-haul signaling for different cell-free topologies considered in the literature. It also proposes efficient algorithms for distributed MIMO processing of RadioWeaves with centralized and decentralized approaches.
D6.1 “Internal and external IT communication infrastructure and project website”
This deliverable presents the REINDEER communication kit, including the project’s visual identity as well as communication and dissemination materials, which are used within the project.

This report constitutes an updated plan and initial report on the partners` dissemination and communication activities of the first 12 months. It also includes an overview of the advancements in terms of spectrum harmonization that took place in different radio regulatory bodies (e.g. as the ITU), and a short forecast on how current advancements may shape 6G in terms of, e.g. overall requirements, allocated spectrum parts, etc.
D7.1 “Project Quality Plan”
This Project Quality Plan constitutes a set of project templates and explanations on the project management process, review process, quality checks and meeting organisation, which are communicated to all partners.
