DSS 2.0
AI-Driven Real-Time Dynamic Spectrum Sharing
Machine learning spectrum sharing that allocates individual subcarriers and time slots between legacy 5G and 6G users in sub-milliseconds without static partitioning.
Technical Explanation
While 5G Dynamic Spectrum Sharing (DSS) used static rate allocations that caused performance penalties for both 4G and 5G users, DSS 2.0 employs deep reinforcement learning. Operating at sub-millisecond slot levels, DSS 2.0 monitors instantaneous buffer queues and channel conditions across both 5G and 6G devices, dynamically assigning individual resource blocks to whichever device derives the highest utility with zero guard-band waste.
Key Functions
- Sub-millisecond dynamic spectrum allocation between 5G NR and 6G air interfaces
- Zero static spectrum reservation or wasted guard-band frequency buffers
- Deep reinforcement learning optimizing network sum-rate capacity across generations
- Accelerating commercial 6G deployment by repurposing existing 5G mid-band spectrum
- Harmonious coexistence between legacy mobile users and next-gen holographic streams
