Strong SPEED-5G presence at EuCNC 2017 in Oulu
About 600 participants from 32 countries attended the 26th edition of the European Conference on Networks and Communications – EuCNC 2017, which took place in Oulu, Finland, on 12 to 15 June 2017. In the exhibition they had the choice between 40 booths. One of them was the SPEED-5G booth, which attracted considerable interest.
The SPEED-5G booth had the title “Quality of Service Provision and Capacity Expansion through Extended-DSA for 5G” and included two demos.
Demo 1: Dense, unplanned, small-cell deployment, multiple mobile users
For a very large deployment of small cells, with randomly placed cells and UEs, and in the interference-limited case, we have an exact theoretical formula for the distribution of Shannon capacity across users. We propose to take this as a benchmark for achievable system performance in the un-optimized situation, and demonstrate the improvements possible with the SPEED-5G cRRM architecture and its optimization algorithms. The demo will consider the whole distribution of bitrate, not just the average or maximum.
The demo software uses an accurate radio model, allowing estimation of SIR at UEs, which is then mapped onto a bitrate depending on the technology. Our propagation modelling takes into account the effects of different frequencies. We can thus show the benefits of multiple RATs, each with its specific parameters such as bandwidth and range of modulation schemes.
Demo 2: Hierarchical management for RAT/spectrum/channel selection
This demo shows the impact of a proposed algorithm which has been designed and developed in the context of Speed-5G for radio resource management (RRM) to cells in order to serve UEs in (un-)licensed and light-licensed (3.5GHz) bands. For the 3.5 GHz band the SAS (Spectrum Access System) model is considered which takes into account incumbents, primary access and general access users.
In addition, SPEED-5G was also very active in the conference part via a special session and two workshops.
In a special session on “Trends and Challenges for Autonomic RRM and MAC Functionality for QoS Provision and Capacity Expansions in the Context of 5G Beyond 6GHz”, Andreas Georgakopoulos from WINGS ICT Solutions presented the main SPEED-5G innovations on MAC and RRM, including the adoption of the eDSA. Particularly, the innovations he presented consist of enhanced resource management techniques with three degrees of freedom: densification, rationalized traffic allocation over heterogeneous wireless technologies, and better load balancing across the available spectrum for next generation networks in below and above 6GHz bands.
In addition, SPEED-5G was the co-organizer of two workshops, which took place on Monday, 12 June 2017.
The “2nd edition of the 5G PPP Workshop on 5G PHY/ MAC Layers Design and Hardware Aspects Below and Above 6 GHz” (Workshop 3) presented major conclusions and results of the FANTASTIC-5G, SPEED-5G and Flex5GWare projects on the design of the new 5G air interface. This specifically included the findings regarding 5G new waveforms, flexible air interface for the 5G vertical market, coexistence issues, flexible and adaptive novel MAC design, and a much more dynamic management of the available spectrum resources and advanced sensing techniques. The workshop was organised together with FANTASTIC-5G and Flex5GWare.
The other workshop was dedicated to “Business models and techno-economic studies for 5G networks” (Workshop 6). This workshop focused on relevant business- and techno-economic-aspects of future 5G networks. It provided insight on the business impacts and opportunities from the deployment of 5G networks for all actors in the telecommunications ecosystem such as verticals, incumbent and new operators, service providers, application developers, content providers, regulators, and equipment manufacturers. The participants discussed the potential for new roles such as brokers, aggregators and marketplaces. The workshop was organised together with CHARISMA, SESAME, COHERENT, VirtuWind, NORMA, 5GEx, mmMAGIC, and SELFNET.
