Inter-Frequency Measurement Prioritization for Flexible Frame Structure 3
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) configured with measurement gaps for performing inter-frequency License Assisted Access (LAA) measurements may not meet the specified requirements, particularly when measurement gaps overlap with Discovery Measurement Timing Configuration (DMTC) occasions on secondary component carriers (SCCs).
Innovation Solution
The UE determines the overlap between timing resources for intra-frequency and inter-frequency measurements and prioritizes them based on the amount of overlap, allowing it to perform measurements according to specified time requirements while relaxing requirements for lower-priority measurements during overlaps, using flexible frame structure type 3 (FS3) operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are configured for inter-frequency LAA measurements, then measurement capability is improved, but timing requirements cannot be met when gaps overlap with DMTC occasions on SCCs
Solution Approach 1:
The patent implements dynamic prioritization of measurement tasks based on timing overlap detection. When measurement gaps overlap with DMTC occasions, the system dynamically adjusts measurement priorities and relaxes timing requirements for lower-priority measurements, allowing the UE to adaptively manage conflicting measurement schedules while maintaining overall measurement capability
Solution Approach 2:
The patent applies partial action by selectively relaxing timing requirements only for lower-priority measurements during overlap periods, while maintaining strict timing compliance for higher-priority measurements. This partial relaxation approach allows the system to meet critical timing requirements while still performing measurements during overlap conditions
2Productivity
If measurement gaps overlap with DMTC occasions on SCCs, then more measurement opportunities are available, but measurement timing requirements cannot be satisfied
Solution Approach 1:
The system performs partial measurement relaxation by identifying lower-priority measurements during overlap periods and applying relaxed timing requirements only to those specific measurements, while maintaining full timing compliance for higher-priority measurements. This allows the UE to utilize overlap periods for additional measurements without compromising critical timing requirements
3Measurement precision
If the UE prioritizes intra-frequency measurements, then intra-frequency measurement accuracy is improved, but inter-frequency measurement timing requirements may not be met
Solution Approach 1:
The patent implements dynamic priority adjustment based on measurement type and timing conditions. The system evaluates both intra-frequency and inter-frequency measurement requirements, and dynamically adjusts priorities to ensure inter-frequency measurement timing compliance is maintained while still performing intra-frequency measurements with high accuracy
