MWC Barcelona is a key networking opportunity for the mobile and tech industries, attracting some of the most influential decision-makers. Over 2.000 leading companies will attend and share their insights on future connectivity trends.

Meet the Affordable5G partners

The Affordable5G consortium could not miss this opportunity! Come to meet the Affordable5G partners at the MWC 2022 and receive first-hand insights on the project results and next steps.

In hall 2, stand 2C32, Atos (the project coordinator) will host a demo of Affordable5G AI-control loop for radio parameters optimisation, declared as a xApp in RT-RIC according to O-RAN disaggregation scheme.

Moreover, for the entire duration of MWC 2022, you can ask further questions to our partners present as exhibitors on the showfloor: RunEL (hall 6 – 4YFN, stand 6C8.3), Nearby Computing (hall 4, stand 4B150, together with Cellnex), and Accelleran (hall 7, stand 7G51).

Project partner Athonet will be presenting demos in some of their clients’ booths: Parallel Wireless (hall 5, booth 5C61), Vodafone (hall 3, booth 3E11), and Amazon Web Services (hall Conference Center CC1).

Affordable5G is looking forward to meeting you all!

The implementation gave us the opportunity to set and simulate a realistic operation of the Near-RT towards the achievement of an ML-assisted optimization objective. The algorithm is based on a Deep Reinforcement Learning (DRL) based approach, according to which the O-RAN is optimized in terms of the experienced throughput. Specifically, given the UE measurement reports (collected from the O-RAN), the algorithm aims to maximize the network throughput by providing a power allocation scheme for all Physical Resource Blocks (PRBs) of all active RUs. To that end, a DRL agent (xAPP2) is trained on simulated network measurements obtained from mobile users inside a three-cell area (provided by xAPP1).

The implementation framework starts with a simulation environment in order to (i) train the DRL agent in realistic and 5G-compliant network conditions and (ii) test and validate the deployed algorithm by using the simulated data for model inference purposes. To concretely describe the architecture of this scenario, Fig. 1 illustrates the dRAX (Accelleran’s Near-RT RIC) building blocks, especially focused on the support of xAPPs. The algorithm supports time-varying numbers of users, given that UEs may enter or exit the network area, according to their trajectories. In addition, the network simulator is aware of possible handovers, since a UE may be served from different RUs depending on which is the best server for a given time point. The key functionality of the simulator includes the interference calculations for each UE by not only considering the channel losses but also the accumulated interference caused by other radios. At each time point, a UE measurement report vector is published in the dRAX RIC Databus through the Databus publisher. This vector is then available to the Databus listener of the xAPP2 for model inference purposes.

Overall, this implementation brought together the National and Kapodistrian University of Athens (ML deployment) and Accelleran (dRAX integration), allowing the realization of a practical intelligence scenario in the O-RAN environment.

The post Affordable5G’s xAPP integration appeared first on Affordable5G project.

It includes cell densification, Remote Units/Distributed Units/Central Units RU/DU/CU split, hardware acceleration, edge computing and core network virtualization, seamlessly combined with the adoption of open solutions, such as O-RAN (Radio Access Network), MEC (Mobile Edge Computing) and open source MANO (Management and Orchestration) solutions, for cloud-native, micro-service deployments. The solution will be evaluated and validated in two vertical pilots related to emergency communications and smart cities.

Affordable5G gathers 17 partners from 10 European countries (Spain, Greece, Belgium, Italy, Portugal, Switzerland, Luxemburg, Cyprus, and France) and Israel who will work together for 2 years.

The Affordable5G consortium is a truly, multidisciplinary consortium, encompassing major industrial companies, SMEs and Research Institutions and Universities.
It brings together two large industrial service provider Partners: Atos, Cellnex and one big vendor: ADVA. They will transfer the Affordable5G results into provisioned services and products.

Part of the consortium are also 10 innovative SMEs: Martel, Accelleran, Athonet, Think Silicon, Ubiwhere, RunEL, Nemergent, 8bells, InCites and Nearby Computing; 4 Research Institutes and Universities: Malaga University, National & Kapodistrian University Of Athens, Fundació I2cat and Eurecom.
