Radio Resource Management:
- Radio resource management with a special focus on URLLC applications, for the selection of multi numerology, mini-slots, radio resources, MCS mapping etc.
- The hierarchical radio resource allocation, i.e. D2D (Device-to-device) sub-granting scheme, is seen as a solution to overcome the incurred inefficient radio resource utilization in overlay D2D communications.
- D2D Reuse SON solution that minimizes the impact of URLLC applications on network capacity is based on allowing the sharing of the cellular network’s radio resources with multiple device-to-device (D2D) users.
- Autonomous D2D resource selection protocols for reduced latency and increased spectral efficiency in an out-of-coverage scenario
- Slice management and packet scheduling based on machine learning and other optimization solutions
