TeamUp5G is a European Training Network (ETN) in the frame of the Marie Skłodowska-Curie Innovative Training Networks (MSCA ITN) of the European Commission’s Horizon 2020 framework. ETNs are multi-partner research training networks whose beneficiaries will be drawn from the academic and non-academic sectors to form a structured, international, intersectoral, and interdisciplinary research and training environment for PhD students (read more on MSCA ITN ETNs).
TeamUp5G’s EU funding adds up to 3.72 million Euro between 2019 and 2022.
With the continuous increase of data rates and the number of people using mobile communications, wireless connections are evolving towards 5G. To fulfil the user satisfaction and a plethora of challenging requirements, pivotal to the evolution towards 5G are the ultra-dense networks (UDN) with small-cells (SCs). Nowadays, although there is a worldwide market of SCs, the network solutions have inherent technical limitations, e.g., limited available spectrum, the need to coexist within complex environments of multiple heterogeneous technologies and users. Possibly the most important challenge is the demand of increasing data rates per km2. Indeed, nowadays SCs are mostly plug-and-play devices that are connected to the core network through an existing DSL line that forms the backhaul. For this reason, femto-cells (FCs), very small cells that are installed today, have very-limited cooperation, as communication between them is imperfect, if feasible at all. The “New RAN TEchniques for 5G UltrA-dense Mobile networks” (TeamUp5G) consortium strongly believes that it is possible to leverage the backhaul, enhancing the overall network performance.
The research objectives of TeamUp5G are focused on solving the following three problems:
Interference Management, waveforms and Massive MIMO (mMIMO)
Dynamic Spectrum Management and Optimisation
Energy Consumption Reduction
We will propose metrics and develop energy-aware algorithms and protocols to enhance Small Cells in ultra-dense deployments, making use of massive antenna solutions (mMIMO), millimeter wave (mmW) bands and visual light communications (VLC), in relevant scenarios, through a combination of analytical work, simulation and prototyping.
