Neighboring Cell Measurement Thresholds for Lower Terminal Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LTE systems cause terminals to perform excessive neighboring cell measurements, which consume power unnecessarily.
Innovation Solution
Implementing a measurement method where terminals receive configured thresholds from the network device to determine when to measure and track neighboring cells based on specific conditions, using multi-level thresholds to reduce unnecessary measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal performs neighboring cell measurement whenever the measurement result does not meet criterion S for multiple consecutive times, then the terminal ensures reliable cell selection and handover, but the terminal consumes excessive power due to repeated measurements
Solution Approach 1:
The patent introduces multiple threshold levels (first threshold and second threshold) for measurement quantity values, changing the parameter structure from a single threshold to a multi-level threshold system. This allows the terminal to adjust measurement behavior based on the current measurement value relative to different thresholds, reducing unnecessary measurements while maintaining reliable cell selection and handover decisions.
2Ease of operation
If the network side configures neighboring cell measurement thresholds, then the terminal can optimize measurement timing, but the terminal still performs excessive measurements when thresholds are not configured or when measurement results frequently fail to meet criterion S
Solution Approach 1:
The patent makes the measurement triggering mechanism dynamic by introducing multiple threshold levels and different triggering conditions. Instead of a static single-threshold system, the terminal dynamically adjusts its measurement behavior based on whether measurement values fall above or below the first threshold, between thresholds, or below the second threshold, thereby optimizing measurement timing and reducing power consumption.
3Reliability
If the terminal measures and tracks neighboring cells multiple times according to protocol requirements, then the terminal ensures network coverage and signal quality, but the measurement frequency is excessive and wastes terminal resources
Solution Approach 1:
The patent applies local quality by differentiating measurement triggering conditions based on the specific range of measurement quantity values. Different local conditions (above first threshold, between thresholds, below second threshold) trigger different measurement behaviors, allowing the terminal to perform measurements only when locally appropriate rather than uniformly across all scenarios, thus improving measurement efficiency while ensuring coverage.
