Wireless Terminal Measurement Reporting for Driving Test Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in managing driving test (DT) overhead, particularly in scenarios where terminals are in special states such as overheating or power saving, leading to inefficiencies in measurement reporting and processing.
Innovation Solution
The proposed solution involves configuring terminals and network nodes to minimize driving test overhead by determining terminal states and adjusting measurement reporting accordingly, including the use of special status indicators and configured intervals for out-of-coverage measurements, allowing for reduced measurement performance and recording during inactive states and special conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If terminals perform measurements and transmit measurement reports in all states including special states (overheating, power saving), then measurement data completeness is improved, but terminal energy consumption and processing overhead increase
Solution Approach 1:
The patent implements dynamic measurement reporting behavior where terminals adapt their measurement and reporting actions based on their current operational state. In normal states, terminals perform measurements and report data; in special states (overheating, power saving), terminals modify or suspend measurement activities. This dynamic adjustment resolves the contradiction by making measurement completeness contingent on terminal energy status.
Solution Approach 2:
The patent changes the operational parameters of measurement reporting based on terminal state. When terminals enter special states, they alter measurement reporting parameters (suspending measurements, reducing reporting frequency, or marking data with state indicators). This parameter change allows the system to balance data completeness with energy conservation.
2Measurement precision
If terminals transmit measurement reports with state information indicators, then network processing accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential state information from terminal measurements and transmits only this critical metadata to the network. Instead of transmitting complete measurement datasets from terminals in special states, the system extracts and transmits only the state indicator (e.g., overheating, power saving). This extraction approach improves network processing accuracy by providing context while minimizing signaling overhead.
Solution Approach 2:
The patent introduces state information indicators as an intermediary element between terminal measurements and network processing. These indicators serve as mediators that provide contextual information about terminal conditions without requiring transmission of complete measurement datasets. The intermediary state indicators enable accurate network processing decisions while keeping signaling overhead low.
3Loss of information
If terminals record measurements in idle or inactive states, then measurement coverage is improved, but device complexity and processing burden increase
Solution Approach 1:
The patent implements partial measurement recording in idle or inactive states. Terminals perform and record only essential measurements during idle/inactive states rather than comprehensive measurement sets. This partial action approach improves measurement coverage for critical data while reducing the processing burden and device complexity compared to full measurement recording.
