The post “5G TSN deployment model and time synchronization aspects” Webinar appeared first on Affordable5G project.

Affordable5G’s first year publications can be generally classified into three major categories:

• Presentation of the architectural approach and innovations of Affordable5G
• AI/ML algorithms for network optimization (mainly regarding the RAN part)
• Performance evaluation of massive MIMO configurations in order to support the vision of ultra-dense networking.

In the context of the first category, our main goal was to present the novel approach of the architectural design of Affordable5G, that combines the following key aspects, crucial for a successful and cost-effective deployment of private 5G networks: dis-aggregated multi-vendor 5G RAN with open interfaces; full-fledged 5G Standalone core; data analytics and AI/ML-based network optimization; network slicing; RAN sharing and neutral hosting; resource and service orchestration over heterogeneous infrastructures; network monitoring and telemetry that spans all architectural layers and efficient 5G transport network with support for TSN. A similar approach combining all the aforementioned key enablers for 5G private networks did not occur in international literature, thus motivating us to the aforementioned design and implementation.

In the context of the second category, we have been motivated by the deployment of AI/ML algorithms in 5G and B5G networks, in an effort to proactively manage all network resources and provide high data rate services with improved bandwidth efficiency and minimum latency. Towards this direction, AI/ML techniques are of utmost importance for the deployment of an intelligent, cognitive, and flexible 5G system, primarily due to the memorization and accurate decision-making capabilities. To this end, we were mainly interested in the Deep Reinforcement Learning (DRL) approach, since it has the potential to high-dimensional decision making problems.

In the third category, the promising research field of massive MIMO technology is considered, deployed either in a centralized or in a distributed way, operating in the millimeter wave (mmWave) frequency band. The small size of mmWave antenna configurations provides the unique opportunity to have a multitude of flexible BS deployments for the support of mutable traffic and overall throughput improvement.

The entire list and links to the publications has been updated and it’s available to the public on the dedicated section of the project’s website: be our guest and catch up with the project’s work so far! http://affordable5g.eu/publications/

The post Affordable5G’s first year scientific publications output appeared first on Affordable5G project.

From the abstract of D1.2 (“Affordable5G building blocks fitting in 5G system architecture”):

“The goal of this deliverable is to analytically present the architectural components that will be implemented and integrated during the Affordable5G project. Following the analysis of D1.1 “State of the art, technical system requirements analysis and pilot element descriptions”, the system requirements are mapped to architectural building blocks that can accommodate the functionalities needed for the cost-efficient deployment of private and enterprise 5G networks. To this end, the main enablers driving the Affordable5G architecture are identified, and a comprehensive review of the underlying technologies is provided. The Affordable5G system architecture, leveraging disaggregated multi-vendor RAN with open interfaces (O-RAN), 5G Standalone Core, data analytics and AI/ML-based network optimization, service orchestration and network slicing, RAN sharing and neutral hosting, as well as 5G RAN transport with Time Sensitive Networking (TSN) support, is presented and detailed interactions between the components are described. The deliverable also includes example instantiations of the proposed architecture for the realization of the two project pilots, aiming to demonstrate efficient system support of the Mission Critical Service (MCS) and the Computer Vision Analytics for Emergencies (CVAE) services.”

The deliverable will be available to the public, in the dedicated section of this website, as soon as publication is allowed.
