Livrables

Websites, patent fillings, videos etc. (1)

Webpage of the project

D1.2 will provide the website of the project in a public domain and online available.

Documents, reports (8)

State-of-the-art on PHY mechanisms energy consumption and specification of efficiency enhancement solutions

D3.1 provides a SoTA analysis of the different energy efficiency improvement strategies related to the developments in all WP3 tasks. Architecture of the RU offloading engine and O-RAN AAL in CU-UP are analysed and reported.

Use case identification and demonstration plan

D5.1 will collate and agree the use cases that are proposed by partners working on different WPs for inclusion in the final demonstrators and testbeds. The testbed requirements for each of the use cases will be defined. The KPIs that will be measured as part of the demonstrator activity will be defined with reference to the work in T2.1, in addition to the measurements that will be required to create the KPIs.

D1.1 Management handbook and quality plan

D1.1 contains information about the internal coordination of the consortium and the work procedures. It contains instructions on the collaboration tools as well as management responsibilities.

Data management plan

D1.3 will provide the status and strategy of the project regarding the data management and GDPR and ways to maximise access to and re-use of research data generated by actions with special emphasis in publishing Open Access (OA). This deliverable will evolve during the lifetime of the project.

BeGREEN reference architecture

D2.1 will contain a survey in current state of the art energy efficiency methodologies and achievable results in RAN in order to serve as input for T2.2. The deliverable will focus on different network architectures, energy aware control mechanisms and AI/ML enhanced mechanisms.

State-of-the-art review and initial definition of BeGREEN O-RAN intelligent plane, and AI/ML algorithms for NFV user-plane and edge service control energy efficiency optimization

D4.1 reports the outcomes of T4.1, T4.2 and T4.3 on the SotA review, and will establish the design principles of the BeGREEN intelligent plane and the AI/ML-assisted procedures to enhance energy efficiency of the network user plane functions and the edge assisted service control. An initial design of the BeGREEN intelligent plane developed in T4.1 and the AI/ML algorithms developed in T4.2 and T4.3 will also be included in this deliverable.

Interim project report

D1.4 will provide a summary of the progress of work and management aspects of period M1-M12, and M13-M25 for the Commission officer.

D6.1 Plan for exploitation and dissemination of the results

D6.1 provides the project plan on dissemination actions, the individual and joint exploitation activities, and the standardization contribution plan.
