Terminal Device Measurement Configuration Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the New Radio (NR) communication system, the transition from an inactive state to other states (idle or connected) is not clearly specified for terminal devices, leading to unclear processing of measurement configuration information and potential delays in Carrier Aggregation (CA) and Multi-RAT Dual Connectivity (MR-DC) configurations.
Innovation Solution
A method for wireless communication where a terminal device effectively maintains or obtains measurement configuration information when transitioning between states, ensuring the validity of the configuration and reducing the time delay in CA and MR-DC configurations by releasing, reserving, or updating measurement configuration information based on network instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device transitions from inactive state to idle or connected state without clear measurement configuration processing rules, then state transition flexibility is improved, but configuration delay increases and measurement reliability deteriorates
Solution Approach 1:
The terminal device performs measurement configuration processing in advance during state transitions. When transitioning from inactive state to idle or connected state, the device proactively releases, reserves, or updates measurement configuration information based on predefined rules, ensuring measurement readiness before actual data transmission begins, thus reducing configuration delay
Solution Approach 2:
The patent implements dynamic measurement configuration management that adapts to different state transitions. The terminal device dynamically adjusts measurement configuration based on whether it's transitioning to idle or connected state, and based on whether first measurement configuration information is stored, optimizing the balance between flexibility and configuration speed
2Productivity
If the terminal device releases measurement configuration information when transitioning from inactive state, then memory resources are freed, but measurement reliability deteriorates
Solution Approach 1:
The terminal device applies different quality treatments to measurement configuration information based on local conditions. When transitioning from inactive state, the device selectively releases configuration information only when appropriate (e.g., when transitioning to idle state or when new configuration is obtained), while preserving it when needed (e.g., when transitioning to connected state), ensuring measurement reliability where required while maintaining resource efficiency
3Measurement precision
If the terminal device obtains second measurement configuration information after state transition, then measurement accuracy is improved, but configuration complexity increases
Solution Approach 1:
The terminal device autonomously manages measurement configuration information without requiring complex network intervention. The device independently determines whether to release, reserve, or update measurement configuration based on its current state and stored information, and autonomously obtains second measurement configuration information when needed, reducing overall system complexity while maintaining measurement accuracy

AI summary
A method for wireless communication includes: entering, by a terminal device, a second state from a first state; when the terminal device stores first measurement configuration information used by the terminal device in the first state, releasing, reserving or updating, by the terminal device, the first measurement configuration information; and/or when the terminal device does not store the first measurement configuration information, obtaining, by the terminal device, second measurement configuration information used by the terminal device in the second state, wherein the first state is an idle state or an inactive state, the second state is any one of an idle state, an inactive state or a connected state, and the measurement configuration information is used by the terminal device to obtain a measurement result.
