To meet the exponentially increased system throughput in next generation wireless communications, future cellular networks will need to be highly densified and multi-layered. Ultra-Dense Network (UDN) technologies significantly increase the overall system capacity by extensive frequency reuse across massive number of densified small cells. In highly densified cellular systems, the highly overlapped small cells magnified the Inter-Cell Interference (ICI) and problem of frequent handover at terminals. Based on the new technologies in 5G cellular networks, this project investigates new base station procedure to mitigate above issues. This includes 5G MIMO beam management procedure which provides precise beam control to target User Equipments (UEs) in 3D space. This reduces transmission power and allows the base station to avoid harmful interference to adjacent cells. The 5G virtual cells architecture further reduces ICI by unifying a set of small cells into a large virtualized cell. Intelligent base station (BS) procedure jointly schedule the frequency allocation across these transmit/receive points (TRPs) to avoid the ICI. Frequent handover problem in UDN can also be resolved as no handover is required across neighbouring TRPs anymore. This project will develop the required and procedure for the 5G MIMO and virtual cell architecture. The tidy cell size in 5G UDN systems also increase the concern on data link robustness due to the lack of coverage. In this program, ASTRI will develop the LTE-NR tight interworking procedure introduced in 5G standard. Through the Dual-Connectivity (DC) architecture, 5G users can access both 4G and 5G networks simultaneously. The mature 4G network can guarantee the data link robustness for the 5G users. This allows progressive 5G deployment to reduce the initial investment of the operators. ASTRI is a leading solution provider of 4G technologies and aims to build up solid technical foundation for the 5G UDN systems. A number of companies have shown strong interests in collaborating with ASTRI and adopting our technologies to be developed from this project. Through this project, ASTRI can generate patents, algorithms, and architectures towards R&D in 5G UDN procedures. The project team is having commercial discussions with some initially engaged customers including HBFEC, NXP. Other customers such as Intel, TCL, Foxconn, Spreadtrum, ELTA have approached us for potential technologies licensing from this project.
