5G will constitute the next major breakthrough into mobile telecommunications standards. Preliminary research on the main features of future wireless networks has proposed capabilities that are substantially beyond those defined in the current mobile technologies. Future wireless networks intend to offer solutions addressing to the explosive growth in video traffic, the acute shortage of spectrum, the growing need to minimize the energy requirements of mobile devices and network infrastructure and to cater to the insatiable desire for higher data rates.

RU6 is following the latest developments in the fields of mobile telecommunications and continues its current research with main target to contribute to future mobile systems. Specifically, the research work and the experience of RU6 team on radio resource management, multicast/broadcast services and small cells could contribute to both the standardization and development phase of future mobile networks. More specifically, it will include the following directions:

  • Network architectures and advanced low-cost wireless solutions including ultra-dense small cell deployment that span at a room-level, facilitate D2D communication, and achieve ultra-high bandwidth and minimum delay while at the same time they increase the radio access network capacity achieving at least a ten times increase in frequency reuse
  • Heterogeneous multi-tier networks that combine macrocellular infrastructure with small cells and Wi-Fi deployments as well as advanced interference mitigation techniques, efficient spectrum sharing, energy efficient access and smart distributed mobility management that also considers the network heterogeneity, e.g., the existence of small cells or Wi-Fi access points
  • Multi-hop routing through relay nodes in an opportunistic manner as well as location-independent access through small cell deployment in planes, high-speed trains and ships
  • Optimization of small cells performance and connectivity through efficient backhaul integration and multi-cell OAM functions
  • Combination of small cells and relay nodes under Self Organizing Networks (SON) concept, utilizing innovative schemes to solve deployment in heterogeneous networks
  • Massive distributed high-order spatial multiplexing (MIMO) also for small cells, achieving multi Giga-bps data rates towards the support of an anticipated mobile traffic increase
  • Techno-economic analysis and proposal of business-models for heterogeneous networking
  • Efficient mobile TV, video and radio services provision over mobile networks broadcasting and multicasting solutions with content caching and features approximating DVB
  • Extension of existing system level and link level simulation software to experiment and evaluate the above technologies also with propagation and mobility models adapted to Internet-of-Things

Focusing on the above directions, RU6 is interested in establishing collaboration with pertinent organizations in the frame of the forthcoming calls of H2020.
