The project will develop LTE self-organizing networks (SON) and interference coordination technologies for LTE small cells in order to address the demand on deploying small cells in 4G networks. A LTE heterogeneous network in which the macro cells coverage area overlays with small cells, provides an efficient way to offload data traffic from macro cells to small cells to improve system capacity. The technologies enhance our current LTE small cell baseband core technologies in managing inter-cell interference with intelligent multi-cells coordination, self-configuration and optimization. The project deliverables include (1) enhanced baseband core and protocol stack technologies for SON and interference coordination; and (2) LTE SON small cell reference design including L1 link level and system level simulation platforms, enhanced baseband (L1) and SON-enabled protocol stack modules, Radio Resource Management (RRM) and Medium Access Control (MAC) in L2/L3 supporting SON and interference coordination, and a complete test infrastructure. ASTRI is a leading solution provider of LTE small cell technologies. This project will extend our leadership in baseband technologies for network planning and deployment. This project will provide a competitive edge in LTE market to local/regional silicon supplier, equipment manufacturers, and local operators. A number of companies have shown strong interests in collaborating with ASTRI and adopting our technologies to be developed from this project. Sunnada and Freescale have already decided to contribute to this project. Many other companies such as Haihua, Rohde & Schwarz, 21 Vianet, and Hutchison have also been in contact with ASTRI for possible technology transfer and/or leverage the know-how from this project.
