Solution Overview

Problem

Current wireless communication systems face challenges in efficiently managing power consumption, particularly in adapting encoding algorithms to optimize battery life and network performance, as they often rely on single-level encoding schemes that may not dynamically adjust to varying channel conditions.

Innovation Solution

Implementing a multi-level coding scheme that specifies a first encoding algorithm for level 1 coding and a second encoding algorithm for level 2 coding based on power management, allowing network entities and user equipment to dynamically switch between these algorithms to reduce power consumption while maintaining commensurate performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If single-level encoding schemes are used, then device complexity is reduced, but power consumption efficiency deteriorates

Engineering Contradiction:
Improvepower consumption efficiencyVSAvoidencoding scheme complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The encoding scheme is divided into multiple levels (first level encoding algorithm and second level encoding algorithm), where each level handles different aspects of error protection. This segmentation allows the system to selectively apply appropriate encoding complexity based on channel conditions, improving power consumption efficiency by avoiding unnecessary complex encoding when channel conditions are good.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically switches between different encoding algorithms based on channel conditions and power management requirements. The network entity can indicate to the UE whether to use the first encoding algorithm or the second encoding algorithm, allowing adaptive adjustment of encoding complexity to optimize power consumption efficiency under varying operational conditions.

Inventive Principle:
Principle #15Dynamics

2Reliability

If complex encoding algorithms are used, then reliability is improved, but power consumption increases

Engineering Contradiction:
Improveprotection against bit errorsVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system changes encoding parameters (algorithm selection) based on channel conditions and power management state. When channel conditions are poor, the system uses more complex encoding algorithms to provide stronger error protection. When channel conditions are good or power saving is prioritized, the system uses simpler encoding algorithms, thus adapting the reliability level to actual needs and reducing unnecessary power consumption.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The network entity receives feedback about channel conditions and power management state, then adjusts the encoding algorithm selection accordingly. This feedback mechanism ensures that complex encoding algorithms are only used when actually needed for reliability, rather than being applied continuously, thereby reducing overall power consumption while maintaining necessary protection against bit errors.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If adaptive encoding is implemented, then adaptability to channel conditions is improved, but device complexity increases

Engineering Contradiction:
Improveadaptation to channel conditionsVSAvoidencoding scheme structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements a universal multi-level encoding framework that can handle multiple channel conditions and power management scenarios. The same encoding structure (with first and second level algorithms) serves multiple functions: providing different levels of error protection, adapting to varying channel conditions, and supporting power management requirements. This multi-functionality achieves adaptability without requiring entirely separate encoding systems for each scenario.

Inventive Principle:
Principle #6Universality (Multi-functionality)
