Cell Measurement Policy for NTN Frequency Selection and Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) in non-territorial networks (NTN) experiences unnecessary power consumption due to measuring frequencies with high priority, despite NTN's large coverage, leading to inefficient frequency selection and increased power loss.
Innovation Solution
A cell measurement processing method and device that involves sending a measurement policy parameter from a base station to UE, indicating target frequencies and their priorities, regions, and measurement sequences, enabling targeted frequency measurement and reducing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE measures all high priority frequencies in NTN, then frequency selection reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by differentiating measurement requirements based on geographic location. The network configures different measurement policies for terrestrial regions versus non-terrestrial regions, allowing UE to apply appropriate measurement strategies locally rather than uniformly across all regions, thus reducing unnecessary power consumption in NTN while maintaining reliability where needed
Solution Approach 2:
The patent implements dynamics by making the measurement policy configurable and adaptable. The network can dynamically adjust measurement parameters such as measurement bandwidth, frequency lists, and measurement triggers based on current network conditions and UE location, allowing the system to optimize between reliability and power consumption in real-time
2Measurement precision
If UE performs comprehensive frequency measurement in NTN, then measurement precision is improved, but measurement time increases
Solution Approach 1:
The patent extracts unnecessary measurement activities by identifying and removing non-essential frequency measurements in NTN scenarios. By configuring specific frequency lists and measurement conditions that exclude redundant measurements, the system maintains measurement precision for relevant frequencies while reducing overall measurement time and complexity
Solution Approach 2:
The patent applies partial action by performing measurements only on a subset of frequencies that are most relevant to the current situation. Instead of measuring all high priority frequencies universally, the network configures UE to measure only specific frequencies in NTN, achieving sufficient measurement precision for the context without the overhead of comprehensive measurement

AI summary
A cell measurement processing method, applied to a base station, includes sending a measurement policy parameter to a user equipment (UE). The measurement policy parameter is configured to indicate a measurement parameter of at least one target frequency of the UE in a target region.
