Early Measurement Reporting Using Cell Reselection Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, user equipment (UE) currently performs early measurement reporting (EMR) measurements continuously, consuming battery power and resources, even when not required, which can lead to unnecessary power consumption and unreliable measurement results, especially when transitioning between RRC states.
Innovation Solution
The implementation of an enhanced early measurement reporting (EMR) procedure where the UE determines its configuration for EMR and initiates measurements only when necessary, using cell reselection measurements as EMR measurements, and saving configurations to perform measurements after transitioning to an RRC_IDLE or RRC_INACTIVE state, allowing for efficient power conservation and reliable reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment performs early measurement reporting measurements continuously, then measurement availability is improved, but battery power consumption increases
Solution Approach 1:
The patent applies dynamics by transitioning from continuous static measurement to conditional dynamic measurement. The UE determines whether to perform EMR measurements based on current RRC state and network configuration, adjusting measurement behavior dynamically rather than continuously operating.
Solution Approach 2:
The patent implements periodic measurement reporting where the UE reports measurements at specific intervals or trigger events rather than continuously. Measurements are performed periodically based on RRC state transitions and network indications, consuming power only when needed.
2Reliability
If user equipment performs early measurement reporting measurements continuously, then measurement reliability is improved, but measurement accuracy deteriorates due to unnecessary measurements
Solution Approach 1:
The patent employs feedback mechanisms where the network provides indications to the UE about whether EMR measurements are required. The UE uses this feedback information to determine when to perform measurements, ensuring measurements are conducted only when necessary for accurate reporting.
Solution Approach 2:
The patent applies preliminary action by having the UE determine configuration status before performing measurements. The UE checks whether it is configured for EMR and whether measurements are needed based on current state, avoiding unnecessary measurements that would reduce accuracy.
3Use of energy by moving object
If user equipment saves configuration for later measurements, then power consumption is reduced, but measurement timing flexibility is limited
Solution Approach 1:
The patent resolves this contradiction through dynamic measurement execution. While configurations are saved to reduce power consumption, the UE can still perform measurements dynamically when triggered by RRC state transitions or network indications, maintaining timing flexibility.
Solution Approach 2:
The patent applies self-service by having the UE autonomously determine when to execute saved measurements based on its own state and received indications. The UE manages its own measurement timing without external control, balancing power savings with operational flexibility.

AI summary
A method, apparatus, and a computer-readable storage medium are provided for using\ regular measurements for early measurement reporting. In an example implementation, the method may include a user equipment determining that the user equipment is configured for enhanced early measurement reporting, performing cell reselection measurements based at least on a cell reselection configuration, and using the reselection measurements for early measurement reporting when the user equipment is configured for enhanced early measurement reporting.
