Wireless Link Management Using Selective Candidate Cell Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) in wireless communications consumes significant power when performing link management (LM) operations on multiple cells or cell groups, leading to increased power consumption.
Innovation Solution
The UE selectively performs LM operations on a subset of cells or cell groups, reducing power consumption by optimizing link management operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs link management operations on multiple cells or cell groups, then the service quality and system capacity are improved, but the power consumption increases significantly
Solution Approach 1:
The patent segments the set of multiple cells or cell groups into a subset that the UE will actively manage through link management operations. Instead of treating all cells uniformly, the system divides them into groups where only certain cells require full LM processing, thereby reducing the overall computational and power burden while maintaining service quality on critical cells.
Solution Approach 2:
The patent applies partial action by performing link management operations on only a subset of cells rather than all configured cells. This selective approach allows the UE to maintain adequate service quality on essential cells while avoiding the excessive power consumption that would result from managing all cells with equal intensity.
2Productivity
If the UE performs link management operations on multiple cells or cell groups, then the mobility performance is improved, but the power consumption increases
Solution Approach 1:
The patent segments cells into subsets based on mobility requirements, applying full link management operations only to cells that are critical for mobility performance. This segmentation allows the system to maintain good mobility performance on essential cells while reducing power consumption by limiting intensive LM operations to a manageable subset.
Solution Approach 2:
The patent applies local quality by differentiating the level of link management effort applied to different cells based on their specific roles and importance for mobility. Critical cells receive full LM attention to maintain mobility performance, while less critical cells receive reduced or no LM operations, optimizing the balance between mobility and power consumption.
