| Outline of Final Research Achievements |
With the tremendous growth of mobile applications and devices in recent years, there is a common belief that we are facing a severe shortage of radio spectrum in the near future. Currently, the spectrum resources under 6GHz is allocated to the primary user in a static and exclusive way, which is highly inefficient.
To improve the spectrum utilization efficiency, we proposed a novel negotiated spectrum access (NSA) approach, whereby PUs proactively and explicitly negotiate with SUs. The evaluation results show that the proposed framework could improve the spectrum utilization efficiency and the QoS of individual users simultaneously.
