Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power regulation techniques are used, then power levels can be regulated, but uplink transmission performance is degraded and data rates are reduced
Solution Approach 1:
The patent implements dynamic power regulation by calculating a maximum power reduction backoff value based on the aggregate bandwidth configuration. Instead of using static power levels, the system dynamically adjusts the transmit power according to the actual bandwidth usage in both downlink and uplink, allowing optimal power levels to be maintained while preventing performance degradation.
Solution Approach 2:
The system changes the power parameter dynamically by computing the maximum power reduction backoff value as a function of bandwidth configuration. This involves adjusting the power level based on the aggregate bandwidth to ensure that power is allocated efficiently, improving both transmission reliability and data rates simultaneously.
2Productivity
If transmission power is increased to improve data rates, then productivity increases, but power consumption and interference increase
Solution Approach 1:
The system optimizes the power parameter by calculating it based on the aggregate bandwidth configuration. This ensures that power consumption is directly tied to the actual transmission needs, allowing data rates to be maximized without unnecessarily increasing power consumption beyond what is required for the given bandwidth utilization.
Solution Approach 2:
The patent employs a feedback mechanism where the maximum power reduction backoff value is calculated based on the configured bandwidth and actual usage patterns. This feedback loop allows the system to adjust power levels in response to changing conditions, ensuring that power consumption is optimized while maintaining high data rates when bandwidth is actively used.
3Productivity
If transmission power is increased to improve data rates, then productivity increases, but interference to other users increases
Solution Approach 1:
The system adjusts the power parameter dynamically based on the aggregate bandwidth configuration, ensuring that interference is minimized while maintaining high data rates. By tying power levels to actual bandwidth usage, the system avoids generating excessive interference when full bandwidth is not being utilized.
4Measurement precision
If aggregate bandwidth configuration is used for power calculation, then power regulation accuracy improves, but device complexity increases
Solution Approach 1:
The patent implements a universal power calculation approach where the maximum power reduction backoff value is derived from the aggregate bandwidth configuration that already exists for resource management. This multi-functional use of the bandwidth configuration data allows accurate power regulation without requiring separate complex measurement and calculation systems.
Solution Approach 2:
The system uses its own existing bandwidth configuration data to calculate the power backoff value, eliminating the need for external or additional complex measurement systems. The bandwidth configuration that is already being used for resource allocation serves dual purposes by also enabling accurate power regulation.
