Terminal Frequency Measurement Gating for NTN Cell Reselection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a terminal is located in a non-terrestrial network, cell reselection to a terrestrial network can be problematic, leading to unnecessary measurements and increased power consumption.
Innovation Solution
A method and apparatus for measurement determination that allows a terminal to determine whether to measure a frequency based on area information configured by a network device, optimizing frequency measurements to save power and ensure timely reselection to cells with higher priority or better communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal performs cell reselection measurement on all frequencies in non-terrestrial network, then the terminal can ensure timely reselection to terrestrial network cells, but the terminal consumes excessive power due to unnecessary measurements
Solution Approach 1:
The patent applies local quality by configuring different measurement requirements for different geographic areas. Area information is associated with specific frequencies, and the terminal only measures frequencies that are relevant to its current location. This resolves the contradiction by making measurements locally relevant rather than universally applied, ensuring reliable reselection where needed while avoiding unnecessary measurements elsewhere.
Solution Approach 2:
The patent applies preliminary action by pre-configuring area information and frequency associations through network signaling before the terminal needs to make reselection decisions. The network device provides area information in advance, allowing the terminal to determine measurement requirements ahead of time rather than continuously monitoring all frequencies, thus reducing power consumption while maintaining reselection reliability.
2Measurement precision
If the terminal continuously measures all frequencies to ensure timely reselection, then the measurement accuracy is maintained, but the measurement complexity and processing overhead increase
Solution Approach 1:
The patent applies the taking out principle by extracting only the relevant frequencies for measurement based on area information. Instead of processing all frequencies, the terminal extracts and measures only those frequencies associated with the current area, reducing measurement complexity and processing overhead while maintaining measurement precision for the relevant frequencies.
Solution Approach 2:
The patent applies segmentation by dividing the frequency measurement task into area-specific segments. Each area has its own associated frequencies, and the terminal processes measurements separately for each area-frequency combination rather than as a single monolithic process, reducing overall complexity while maintaining accuracy.

AI summary
The present disclosure relates to the technical field of communications, and specifically relates to a measurement determination method and apparatus, and a communication device and a storage medium. The measurement determination method comprises: according to whether a network device is configured with area information associated with a first frequency, determining whether to measure the first frequency. According to the present disclosure, a terminal may determine, according to whether a network device of a cell where the terminal is located is configured with area information associated with a first frequency, whether to measure the first frequency. When it is difficult for the terminal to re-select a cell corresponding to the first frequency, the terminal may determine to not measure the first frequency, thereby avoiding unnecessary measurement, and thus reducing the power consumption of the terminal.
