UE Energy Partitioning Feedback for Battery-Aware Wireless Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems do not effectively manage energy usage in user equipment (UE) devices, leading to inefficient energy consumption and reduced battery life due to changes in communication schemes without considering the impact on UE energy efficiency.
Innovation Solution
The UE determines a preferred partitioning of energy consumption between baseband and radio interface signal processing and communicates this to the base station, allowing the base station to adjust communication schemes and parameters to optimize energy usage and extend battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station adjusts communication schemes to improve spectral efficiency, then data transfer efficiency is improved, but UE energy consumption increases adversely
Solution Approach 1:
The UE measures its own energy consumption for baseband and radio interface signal processing, then feeds back this information to the base station. The base station uses this feedback to adjust communication schemes that optimize both data transfer efficiency and UE energy consumption, rather than unilaterally adjusting parameters without considering UE energy impact.
Solution Approach 2:
The system dynamically changes communication parameters (such as baseband processing complexity, radio interface configurations) based on the UE's measured energy consumption characteristics. By adjusting these parameters according to actual UE energy usage, the system achieves optimal balance between spectral efficiency and energy consumption.
2Productivity
If the base station changes communication parameters to achieve greater spectral efficiency, then network performance is improved, but battery life of the UE deteriorates
Solution Approach 1:
The UE provides feedback about its energy consumption measurements to the base station, enabling the base station to select communication parameters that maintain spectral efficiency while preserving UE battery life. This feedback loop prevents the base station from imposing overly demanding parameters that would unnecessarily drain UE battery.
Solution Approach 2:
Communication parameters are dynamically adjusted based on the UE's energy consumption profile. When the UE indicates higher energy consumption for certain processing tasks, the base station modifies parameters to reduce the burden, thereby extending battery life while maintaining acceptable network performance.
3Use of energy by moving object
If the UE performs more baseband signal processing to improve data compression efficiency, then energy usage efficiency improves, but the complexity of processing increases
Solution Approach 1:
The UE measures and reports its energy consumption for different levels of baseband signal processing to the base station. This feedback enables the base station to understand the trade-off between processing complexity and energy efficiency, allowing it to select appropriate processing levels that balance these factors.

AI summary
Techniques for improving, for a set of conditions at a UE, the usage of energy stored at a UE include determining a preferred or requested partitioning of the UE's stored energy usage during wireless data transfer between the UE and the base station (e.g., an amount or percentage of stored energy utilized by the UE for baseband signal processing with respect to the amount or percentage of energy utilized by the UE for radio interface signal processing tasks), and indicating the preferred partitioning to the base station or network. Based on the indication, the base station/network may modify the baseband communication scheme, parameters, and/or values, and/or the radio interface communication scheme, parameters, and/or values utilized for the wireless transfers of data between the base station and the UE, thereby better managing (and in some cases, optimizing) the UE's stored energy usage and increasing battery life at the UE.
