Reconfigurable DSA's on Fixed Hardware for 6G Radio

Abstract: Coarse and fine grained Reconfigurable Domain Specific Accelerators (DSA's) realized on fixed hardware have the potential to disrupt 5G/6G research and solutioning. A many-core runtime reconfigurable processor based on a Dataflow Model of Execution supports SIMD and MIMD workloads on same processor fabric  - capable of realizing diverse and elastic 5G/6G AI-ML, DSP, and HPC (Digital Twins/Metaverse) like workloads. This enables an integrated approach for transitioning from research to production solutioning due to seamless scalability and ability to implement in any Distributed Unit (DU) that supports O-RAN AAL. In addition to the scalability, flexibility, and post silicon reconfiguration functionality enabled by Reconfigurable Dataflow Architecture -  class leading Power, Performance, and cost-effective implementations can be realized for next generation 5G/6G infrastructure setups.

The role of Open Smart Networks beyond 5G

Abstract: 5G is essential to enable virtually competitiveness in all sectors. As 5G deployments grow across Europe, current networks will not require only reliability, speed, mobility and security as main key driving factors but also others like capacity, ultra-low latency, machine connectivity and network slicing. Besides, current geopolitical situation has leaded to even give higher priority to energy efficiency, the networks need to run efficiently.

The evolution of the future networks beyond 5G will require fully interoperable networks across main domains. The Open Smart Network and Services working group under the 6G-IA works not only on defining a number of requirements where research and development in EU needs to take a leading role catalysed by all the industry players but also the status and challenges of current open networks.

Network AI: Enabling 6G Pervasive Intelligence

Abstract: Mobile communication standards were developed for enhancing transmission and network performance by using more radio resources and improving spectrum and energy efficiency. How to effectively address diverse user requirements and guarantee everyone's Quality of Experience (QoE) remains an open problem. The Sixth Generation (6G) mobile systems will solve this problem by utilizing heterogenous network resources and pervasive intelligence to support everyone-centric customized services anywhere and anytime. In this talk, we first coin the concept of Service Requirement Zone (SRZ) on the user side to characterize and visualize the integrated service requirements and preferences of specific tasks of individual users. On the system side, we further introduce the concept of User Satisfaction Ratio (USR) to evaluate the system’s overall service ability of satisfying a variety of tasks with different SRZs. Then, we propose a network Artificial Intelligence (AI) architecture with integrated network resources and pervasive AI capabilities for supporting customized services with guaranteed QoEs. Finally, extensive simulations show that the proposed network AI architecture can consistently offer a higher USR performance than the cloud AI and edge AI architectures with respect to different task scheduling algorithms, random service requirements, and dynamic network conditions.

What We Can Anticipate Today for 6G AI/ML for Open RAN

Mr. Douglas Knisely, Qualcomm, USA


6G in Europe: Status and perspective

Abstract: R&I initiatives on 6G technologies are now starting in leading regions world-wide, with the first products and infrastructures expected by the end of this decade. In Europe, exploratory work on 6G started in 2020 with the Hexa-X flagship system project. The Smart Networks and Services (6G) initiative was also launched with the support of stakeholders and recently delivered a first batch of 35 exploratory projects aimed at preparing Europe for the 6G standardisation period expected to start mid of the decade. Those are aligned with a 6G vision targeting a step change in our ability to interact with the physical and human world, using massively digital representations and “twins” of the real world to intelligently sense and interact with it. It calls upon new technologies and architectures where native AI has a central role, whilst full programmability, real time data analytics, Terabit capacities and sub-millisecond response times, end to end security are needed to enable new critical and highly immersive applications . Moreover, new smart network technologies and architectures will need to drastically enhance sustainability of connectivity infrastructures to manage major traffic growth while keeping electromagnetic fields (EMF) under strict safety limits. These technologies will form the basis for a human- centric Next-Generation Internet (NGI) and address Sustainable Development Goals (SDGs) such as accessibility, limitless access and affordability of technology. At the same time, multiple developments in the , economic and industrial landscape are taking place, which are likely to have an impact on how 6G gets developed globally. Against this background, the presentation will outline how Europe is progressing towards 6G, with a focus on the technological, industrial, standardisation and international cooperation challenges to address.
