1Productivity
If a single communication configuration is used for the entire bandwidth, then device complexity is reduced, but communication performance deteriorates because the configuration cannot be optimized for specific bandwidth regions with different noise levels
Solution Approach 1:
The bandwidth is divided into multiple bandwidth regions (e.g., first bandwidth region, second bandwidth region) with different noise characteristics. Each region is configured with its own communication parameters including modulation order and coding scheme, allowing optimized performance for each region while managing complexity through structured segmentation.
Solution Approach 2:
Different communication configurations are applied to different bandwidth regions based on their specific noise levels. The first bandwidth region with lower noise uses higher modulation orders (e.g., 64QAM), while the second bandwidth region with higher noise uses more robust modulation (e.g., QPSK), ensuring each region receives tailored optimization.
2Measurement precision
If noise information is reported with fine granularity across multiple bandwidth regions, then measurement precision of channel conditions is improved, but loss of time increases due to more frequent or complex reporting requirements
Solution Approach 1:
The bandwidth is segmented into multiple regions, and noise information is reported separately for each region. This allows precise characterization of noise conditions in each segment without requiring continuous reporting across the entire bandwidth, optimizing the balance between precision and time.
Solution Approach 2:
The system performs preliminary configuration setup where bandwidth regions are predefined and associated with specific reporting requirements. This allows efficient noise measurement and reporting without requiring real-time analysis of the entire bandwidth, reducing time loss while maintaining precision.
3Productivity
If adaptive modulation and coding schemes are implemented for different bandwidth regions, then productivity of data transmission is improved, but device complexity increases due to multiple configuration management requirements
Solution Approach 1:
The transmission system is segmented into multiple bandwidth regions, each with its own modulation and coding scheme (MCS) configuration. This allows independent optimization of data transmission rates for each region while managing complexity through standardized segmentation frameworks.
Solution Approach 2:
The system dynamically selects and switches between different modulation orders and coding schemes based on the noise characteristics of each bandwidth region. The modulation order can be adjusted (e.g., using 64QAM in low-noise regions, QPSK in high-noise regions) to optimize transmission performance while maintaining manageable complexity through dynamic adaptation.
