Measurement Gap Configuration via Selective Capability Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE-A networks with Carrier Aggregation technology, the existing method of reporting measurement capability information once for all scenes results in significant signaling overhead and waste, especially when the terminal's configuration changes.
Innovation Solution
The method involves determining the current and future aggregation states of component carriers, and sending measurement capability information only for the relevant configurations, reducing unnecessary signaling and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal sends measurement capability information for all scenes once, then the base station can configure measurement gaps for all possible frequency points, but the signaling overhead becomes large and signaling is wasted
Solution Approach 1:
The patent segments the measurement capability information reporting by dividing all possible frequency points into multiple groups or scenes. Instead of reporting all capability information at once, the terminal reports measurement capability information selectively for each scene or group of frequency points based on current configuration states, thereby reducing the总量 of signaling overhead while maintaining complete measurement capability coverage across all scenes
Solution Approach 2:
The patent implements dynamic reporting of measurement capability information based on the terminal's current configuration state and the aggregation configuration state of carriers. The terminal adaptively determines which measurement capability information to report in each scene, changing the reporting behavior dynamically rather than using a static one-time report for all scenes, thus optimizing signaling efficiency
2Adaptability or versatility
If the terminal reports measurement capability information for all frequency points, then all measurement scenarios are covered, but resource efficiency decreases due to unnecessary signaling
Solution Approach 1:
The patent applies local quality by making the measurement capability information reporting tailored to specific local scenes or frequency point groups rather than uniformly reporting for all frequency points. The terminal reports measurement capability information selectively for each local scene based on current configuration, ensuring adequate measurement coverage for active frequency points while avoiding unnecessary signaling for inactive or future frequency points
