UE Measurement Configuration via Priority Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Carrier Aggregation scenarios of LTE and NR systems, User Equipment (UE) in a non-connected state performs unnecessary measurements on multiple frequencies of cells in different systems, leading to resource waste.
Innovation Solution
A measurement configuration method where UE obtains priorities for measurement indication information and measures specific frequencies based on these priorities, reducing unnecessary measurements by focusing on target measurement indication information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UE measures multiple frequencies of LTE cell and NR cell in non-connected state, then measurement coverage is improved, but resource waste occurs due to unnecessary measurements
Solution Approach 1:
The patent applies parameter changes by introducing priority levels for different measurement indication information. The network configures priorities for measurement objects, and the UE uses these priority parameters to determine which frequencies to measure first or whether to measure them at all, thereby optimizing resource usage while maintaining measurement coverage.
2Measurement precision
If UE measures all configured frequencies in non-connected state, then measurement completeness is improved, but measurement efficiency deteriorates due to unnecessary measurements
Solution Approach 1:
The patent introduces priority parameters for measurement indication information, allowing the UE to efficiently select which measurements to perform based on network-configured priorities, thereby improving measurement efficiency without sacrificing completeness of necessary measurements.
3Reliability
If network configures measurement information for all cells, then measurement reliability is improved, but device complexity increases due to handling multiple measurement configurations
Solution Approach 1:
The patent simplifies device complexity by introducing priority parameters that enable the UE to automatically filter and prioritize measurement tasks. This reduces the burden of handling multiple measurement configurations while maintaining reliable measurements through priority-based selection.

AI summary
A network side device, and a non-transitory computer-readable storage medium directed to the network side device, and a non-transitory computer-readable storage medium directed to User Equipment (UE) are provided. The network side device includes: a processor, a memory, and a computer program that is stored in the memory and that is executable on the processor. The computer program, when executed by the processor, causes the processor to: send measurement configuration information and first indication information to the UE. The measurement configuration information is configured to indicate priorities of M pieces of measurement indication information, the first indication information is configured to indicate which Radio Access Technology (RAT) type of cell or frequency the UE performs measurements on. The measurement configuration information, used by the UE, is configured to measure a to-be-measured frequency corresponding to target measurement indication information, and M is an integer greater than or equal to 1.
