| How does dynamic spectrum sharing contribute to improving network performance in 6G access networks compared to traditional spectrum allocation methods? |
Dynamic spectrum sharing helps to improve the performance of 6G access networks compared with traditional methods, as it enables more efficient, flexible and reactive use of frequency resources, which is essential to meet the growing demands of 6G networks.
It also improves network capacity by increasing the number of users, reducing access failure rates and optimizing resource utilization.

| How does cognitive radio technology adapt to the evolution of spectrum availability and user requirements in the proposed 6G network architecture? |
By
- Spectrum Detection (Identification of Frequency “Holes”) : CR systems are able to detect unoccupied areas of the spectrum, allowing secondary users (SU) to access these resources without interfering with primary users (PU).
- Continuous monitoring: CR performs real-time monitoring to assess spectrum availability, ensuring that users can always find available channels.
- Dynamic Spectrum Management (Real-Time Adjustment): CR allows users to change frequency according to spectrum availability, adapting to fluctuations in demand and network conditions.
- Resource Prioritization: Spectrum management algorithms assess user needs and prioritize access to resources according to the required quality of service.
- Analysis and Decision (Spectrum Quality Assessment): Spectrum detection results are analyzed to estimate the quality of available channels, enabling CR systems to select the best options for communication.

| Please elaborate the technique features of the proposed method in detail. |
The proposed method for dynamic spectrum sharing in 6G networks is based on several technical features described as follows:
-Primary and Secondary Base Stations** : The architecture comprises primary base stations (PUs) operating on licensed frequencies, and secondary base stations (SUs) opportunistically exploiting the frequency “holes” left by the PUs.
- Multi-user configuration: The method allows several SUs to share frequency resources, thus increasing network capacity.
- Advanced Detection Systems: Use of sophisticated detection techniques to identify available channels - Real-Time Monitoring: Implementation of continuous monitoring mechanisms to assess spectrum availability and detect changes in frequency usage.
- Adaptive Allocation: Frequency resources are dynamically allocated according to user demand and spectrum availability, enabling optimal use.
- Self-coexistence: The method ensures that SUs can coexist without interference by monitoring channel usage and avoiding conflicts.
- Transmission synchronization: SUs are synchronized to avoid simultaneous transmissions on the same channel, thus minimizing interference.
- Interference management: Protocols designed to minimize interference between PUs and SUs
