Enhancing 5G Data Transmission Through Sub-Carrier Spacing Optimization
Keywords:
5G, Subcarrier Spacing, Numerology, Throughput, Delay, JitterAbstract
5G networks can support various UDP and TCP applications. Efficient and reliable 5G network performance offers faster speeds, improved connectivity, and the capability to manage multiple applications across different locations. This study comprehensively analyses the effect of various subcarrier spacing (SCS) scenarios of 5G networks on the performance of smartphones, cameras, and sensors. The analysis shows that higher SCS values are associated with increased average throughput. It indicates that higher subcarrier spacing values enable more efficient data transmission. Smartphones have low and symmetrical jitter with numerology values of 3 and 2, making them well-suited for bidirectional communication. In comparison, cameras are more efficient than sensors at delivering data with a lower delay at all SCS values, which is crucial for applications requiring fast response times. We propose an adaptive Q-learning-based algorithm that automatically adjusts (SCS) configurations based on real-time network conditions and application needs. This approach significantly enhances network performance across various scenarios. The findings of this study have significant implications for the design and implementation of 5 G networks, as they provide insights into the optimal SCS settings for applications with specific requirements and priorities, thereby guiding network engineers and professionals in their decision-making process.
