Engineering Contradiction Analysis
1Productivity
If high data rates are used in 5G wireless communication systems, then data transmission performance is improved, but power consumption increases significantly
Solution Approach 1:
The system dynamically adjusts power consumption parameters based on real-time energy efficiency measurements. The UE determines energy efficiency indicators and provides feedback to the network, which then adapts configuration parameters such as DRX cycles, carrier aggregation settings, and bandwidth part allocations to optimize the balance between data transmission rate and power consumption.
Solution Approach 2:
The patent implements a feedback mechanism where the UE measures energy efficiency, determines an energy efficiency indicator, and reports this indicator to the network. The network uses this feedback to adjust communication parameters, creating a closed-loop system that continuously optimizes power consumption relative to data transmission performance.
2Productivity
If high data rates are used in 5G wireless communication systems, then data transmission performance is improved, but device overheating increases
Solution Approach 1:
The system dynamically adjusts operational parameters to manage thermal conditions. By continuously measuring energy efficiency and adapting configuration parameters such as transmission power, bandwidth allocation, and processing intensity, the system reduces heat generation while maintaining acceptable data transmission rates.
Solution Approach 2:
The energy efficiency indicator serves as a feedback signal that reflects thermal stress conditions. When the indicator shows deteriorating energy efficiency, the network adjusts parameters to reduce power consumption, thereby reducing heat generation and preventing overheating while maintaining data transmission functionality.
3Use of energy by moving object
If energy efficiency is optimized by reducing power consumption, then power usage is improved, but data transmission rate may decrease
Solution Approach 1:
The system dynamically balances power consumption and data transmission rate by adjusting configuration parameters such as DRX cycle lengths, carrier aggregation activation, and bandwidth part allocations. These adjustments are made based on real-time energy efficiency measurements to achieve the optimal trade-off between power savings and maintained data rates.
Solution Approach 2:
The patent changes multiple communication parameters simultaneously to optimize energy efficiency while maintaining data transmission performance. This includes adjusting time-domain parameters (DRX cycles), frequency-domain parameters (bandwidth parts, carrier aggregation), and power parameters, creating a multi-dimensional optimization approach.
