NOMA-6G

Technical Explanation

While Orthogonal Multiple Access (OMA) allocates separate time slots or frequencies to each user to avoid interference, Power-Domain NOMA deliberately overlaps users on the same frequency. The transmitter allocates higher power to users with poor channel conditions and lower power to users with strong channels. The strong user uses Successive Interference Cancellation (SIC) to decode and subtract the weak user's signal before decoding its own, achieving higher sum-rate capacity.

Key Functions

• Overlapping multiple user transmissions simultaneously on identical time-frequency resources
• Exploiting diverse channel power disparities to boost total network sum-rate capacity
• Successive Interference Cancellation (SIC) isolating overlapping user signals cleanly
• Enhanced fairness delivering high data rates to cell-edge users in deep shadow
• Combined with Massive MIMO spatial beamforming for multi-dimensional multi-user multiplexing
