Description:

This project investigates Opportunistic Spectrum Sharing (OSS) technologies for emerging cellular systems. Traditional cellular systems can only utilize exclusive licensed cellular spectrum which is limited and expensive. The OSS technologies overcome this limitation by allowing the cellular systems to access free unlicensed spectrum and non-fully utilized licensed spectrum. This significantly reduces the licensing cost and increase the system bandwidth for cellular systems. This project will investigate the technique to enable the related OSS technologies in upcoming LTE standard. LTE Wi-Fi Link Aggregation (LWA) and License Assisted Access (LAA) are designed for LTE systems to access the unlicensed spectrum. These technologies attract significant interest from cellular operators as the technique provides free spectrum for their systems. Special radio access technique is required to handle the unpredictable channel conditional introduced by uncoordinated sharing devices. Techniques for maintaining the LTE system link robustness and usage fairness when sharing the spectrum with existing standards, such as Wi-Fi, to be investigated. LTE Licensed Shared Access (LSA) is a complementary spectrum licensing technique which allows dynamic use of spectrum whenever and wherever it is not occupied by incumbent users for the licensed spectrum, such as TV station, government or military units. This effectively increases the amount of available spectrum for cellular systems by sub-licensing related spectrum. Also, the primary spectrum license holder or regulatory bodies can generate additional profile by sub-licensing the spectrum for LSA users. This project will design innovative algorithms and develop the simulation platforms for these technologies. The project will also investigate the possible further enhancement for opportunistic spectrum sharing technique for 5G cellular systems. ASTRI is a leading solution provider of LTE small cell technologies. Through this project, ASTRI can generate patents, algorithms, and architectures towards R&D in opportunistic spectrum sharing. Leveraging the project results, ASTRI can benefit Hong Kong and region wireless technology vendors by collaboratively developing more efficient solution for enhancing the spectrum utilization.
