Solution Overview
Problem
Existing communication standards, such as Rel-17, fail to address measurement collisions that occur when multiple types of measurement gaps are used simultaneously, leading to inefficiencies and incomplete cell measurements due to dropped gaps.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple types of measurement gaps are used simultaneously, then measurement coverage and system performance are improved, but measurement collisions occur causing gaps to be dropped and measurement completeness to deteriorate
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the priority levels of different measurement gaps based on their types and current system state. The network device configures priority information for each measurement gap, allowing the system to change the operational parameters of gap management to resolve collisions while maintaining measurement coverage.
Solution Approach 2:
The patent introduces priority information as an intermediary mechanism that mediates between conflicting measurement gaps. This intermediary parameter enables the system to determine which gaps to maintain and which to drop when collisions occur, ensuring measurement completeness is preserved while allowing multiple gap types to coexist.
2Adaptability or versatility
If multiple types of measurement gaps are used jointly, then system versatility is improved, but collision resolution complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring priority information for each measurement gap type before collisions occur. The network device provides priority configurations in advance, allowing the UE to automatically resolve collisions using these pre-established rules without requiring complex real-time decision-making algorithms.
Solution Approach 2:
The patent segments the measurement gap management by dividing different gap types (positioning gaps, mobility gaps, inter-RAT gaps) with distinct priority levels. This segmentation allows each gap type to be managed independently with specific priority rules, reducing overall system complexity while maintaining versatility.
3Device complexity
If measurement gaps are dropped to resolve collisions, then collision resolution is simplified, but measurement precision and completeness deteriorate
Solution Approach 1:
The patent changes the parameter of gap priority dynamically based on measurement requirements. By adjusting priority levels, the system ensures that critical measurement gaps are maintained while less critical gaps are dropped, preserving measurement precision without requiring complex real-time analysis.
Solution Approach 2:
The priority information acts as an intermediary that guides which gaps to maintain during collisions. This intermediary mechanism ensures measurement completeness is preserved by using priority-based decision rules that protect critical measurements while simplifying the overall resolution process.
