Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in reducing energy consumption, particularly in 5G networks where high data transfer rates and extensive IoT applications lead to increased energy demands, necessitating efficient methods to minimize terminal energy usage.
Innovation Solution
A terminal adjusts the bit resolution of its analog-to-digital converter (ADC) to reduce energy consumption, determining an optimal bit resolution value based on energy consumption parameters and reporting this to the base station, which then limits the modulation and coding scheme (MCS) and channel quality indicator (CQI) values to ensure efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal uses high bit resolution ADC to maintain high data transfer rates, then data transmission quality is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of ADC bit resolution based on current channel conditions and traffic requirements. The terminal can switch between different bit resolution modes (e.g., 6-bit, 8-bit, 10-bit) according to real-time network conditions, making the system adaptive rather than static. This resolves the contradiction by allowing high precision when needed and low power mode when acceptable
Solution Approach 2:
The patent changes the physical parameter of ADC bit resolution to balance performance and power consumption. By adjusting this key parameter dynamically, the system can operate at high precision (e.g., 10-bit) for critical data transmission or switch to lower precision (e.g., 6-bit) for less demanding scenarios, directly addressing the energy-quality tradeoff
2Use of energy by moving object
If the terminal uses low bit resolution ADC to reduce energy consumption, then energy efficiency is improved, but data transmission quality deteriorates
Solution Approach 1:
The system dynamically adapts ADC bit resolution based on channel quality indicators and traffic patterns. When channel conditions are good and traffic requirements are moderate, the terminal can use lower bit resolution (e.g., 6-bit) to save energy. When conditions deteriorate or high-quality transmission is required, the system automatically switches to higher bit resolution (e.g., 10-bit) to maintain quality
Solution Approach 2:
The patent implements feedback mechanisms where the terminal monitors channel quality, transmission performance, and power consumption levels. Based on this feedback, the system adjusts ADC bit resolution to achieve optimal balance. The base station also provides feedback on received signal quality, enabling closed-loop optimization of the power-quality tradeoff
3Use of energy by moving object
If the terminal adjusts ADC bit resolution dynamically, then energy consumption is reduced, but device complexity increases
Solution Approach 1:
The patent implements dynamic ADC bit resolution switching with pre-configured resolution levels and decision thresholds. The terminal maintains a set of predefined bit resolution modes (e.g., 6-bit, 8-bit, 10-bit) with associated power consumption characteristics. Switching between these predefined modes reduces the complexity of real-time optimization while still achieving significant energy savings compared to fixed high-resolution operation
