EMR Measurement Validity for Reliable CA/DC Re-Establishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) technologies, when a terminal device transitions from a connected state to an idle state, the Early Measurement Report (EMR) measurement results become invalid or unreliable due to the expiration of timer T331, leading to inefficiencies in re-establishing Carrier Aggregation (CA) or Dual Connection (DC).
Innovation Solution
Implementing a validity condition for EMR measurement results by using network configuration or specification, ensuring that the terminal device performs re-measurement when the validity condition is not met, thereby maintaining the reliability of reported measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If Early Measurement Report (EMR) measurement is performed to speed up CA/DC addition procedure, then connection establishment speed is improved, but measurement result reliability deteriorates due to timer T331 expiration
Solution Approach 1:
The patent applies preliminary action by introducing a validity condition check before using EMR measurement results. The terminal device checks whether the EMR measurement result is valid according to the validity condition (which is determined by timer T331 expiration status) before proceeding with CA/DC addition. This preliminary verification ensures that only reliable measurement results are used, preventing connection establishment based on expired or invalid measurements.
2Productivity
If EMR measurement result is used without validity check, then procedure efficiency is improved, but measurement validity deteriorates
Solution Approach 1:
The patent implements feedback by introducing a validity condition mechanism that provides feedback on whether the EMR measurement result is still valid. The validity condition is based on the expiration status of timer T331, which feedbacks to the terminal device whether the measurement result can be trusted. This feedback loop allows the system to maintain efficiency by using valid EMR results while preventing misuse of expired results, thus balancing productivity with reliability.
