UE Measurement Gap Logic for Inter-Frequency and Inter-RAT Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack a clear method to integrate the behavior of UE for intra-frequency, inter-frequency, and inter-Radio Access Technology (inter-RAT) measurements, leading to configuration conflicts and behavior confusion due to differing capabilities and judgment systems for measurement gaps.
Innovation Solution
A method for UE to determine the need for a measurement gap based on measurement gap configuration information, UE capabilities, and time-frequency position conditions, with network devices providing measurement gap configuration information to indicate the necessity of gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple judgment systems are used for measurement gap determination, then measurement accuracy is improved, but configuration complexity and behavior confusion increase
Solution Approach 1:
The patent segments the measurement gap determination into distinct judgment systems: a first judgment system for intra-frequency measurements and a second judgment system for inter-frequency and inter-RAT measurements. Each system operates independently with its own criteria, eliminating the confusion that would arise from applying a single unified system to all measurement scenarios.
Solution Approach 2:
Different judgment criteria are applied to different measurement types based on their specific requirements. The first judgment system uses criteria appropriate for intra-frequency measurements, while the second judgment system uses criteria tailored for inter-frequency and inter-RAT measurements, ensuring optimal accuracy for each local measurement context.
2Adaptability or versatility
If different support capabilities are used for intra-frequency and inter-frequency measurements, then measurement capability is improved, but compatibility problems arise
Solution Approach 1:
The patent introduces dynamic capability indication through the second judgment system, which allows the UE to signal its specific capabilities for inter-frequency and inter-RAT measurements. This enables the network to adapt the measurement configuration dynamically based on the UE's actual capabilities, ensuring both versatility and reliable operation.
Solution Approach 2:
The patent changes the parameter of measurement capability indication by introducing capability signaling in the second judgment system. This allows the system to adapt to different UE capabilities for inter-frequency and inter-RAT measurements while maintaining compatibility through standardized capability reporting mechanisms.
3Reliability
If additional indication information is added to resolve compatibility issues, then compatibility is improved, but signaling overhead increases
Solution Approach 1:
The patent applies partial action by introducing capability indication only where needed - specifically in the second judgment system for inter-frequency and inter-RAT measurements - rather than adding comprehensive signaling across all measurement types. This minimizes overhead while ensuring compatibility where capability differences matter.

AI summary
A measurement method for user equipment (UE), a terminal device, and a network device are provided. Said method comprises: UE determining, according to at least one of need for gap information, no-gap measurement capability, and time-frequency location condition, a measurement gap that needs to be configured for a measurement corresponding to a frequency point or a cell in a specified list; and the UE performing measurement according to the measurement gap.
