5G Radio Support
The 5G environment includes the development of a new radio network including spectrum allocation, spectral efficiency, physical transmission and radio resource scheduling, which represents a research domain of its own. Additionally, due to delay, efficiency and flexibility requirements, the functionality, now located in the core and backhaul network, will be partially passed to the radio.
In order to bring together the radio and the core network research, we are able to provide know-how and practical implementation of the network support including management and subscriber oriented signaling, dynamic data paths establishment, forwarding and policy based resources allocation, etc. The concepts currently considered are:
- Development of a signaling protocol stack appropriate for the 5G heterogeneity and dynamicity;
- Separation of radio and network management from subscriber mobility and session control;
- Support a new interface to the network, adapted to the radio characteristics – evolution of the S1 interface;
- Architecture design and specification for heterogeneous radio concepts – HetNets, integration of small cells, Licensed Shared Access, Carrier Aggregation, etc.;
- Management and subscriber control for self-backhauling, integrating dynamic front- and back- hauling on top of mobile and fixed networks;
- Support for self-docking of parts of the network to different network areas enabling a harmonized 5G ecosystem, on top;
- Authentication and authorization, resource and mobility control for D2D communication;
- Dynamic spectrum management and base station selection mechanisms.
