Optimizing Base Station (BS) spectrum access is a critical requirement for next-generation 5G and 5G-Advanced networks to maximize data throughput, eliminate signal interference, and lower massive operational energy costs. Next-generation 5G base stations must dynamically handle multi-band environments spanning sub-GHz, mid-band (1 to 6 GHz), and millimeter-wave (mmWave) frequencies. Core Optimization Challenges
Next-generation 5G spectrum access faces unique physical and structural bottlenecks:
Mixed-Numerology Interference: Serving high-bandwidth applications simultaneously with ultra-low latency connections causes severe inter-cell interference.
The mmWave Dilemma: Higher millimeter-wave frequencies provide massive data capacity but suffer from incredibly short range and blockages from physical structures.
Massive Dimension Action Space: Controlling thousands of active antenna arrays simultaneously creates a “curse of dimensionality” for standard computing systems. Advanced Optimization Techniques
