Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-terrestrial networks (NTNs), terminal devices face challenges in discovering terrestrial network (TN) cells in a timely manner due to excessively long or short measurement intervals, leading to poor communication performance.
Innovation Solution
A measurement method where a terminal device selects a first measurement parameter from a set of parameters configured by a network device to perform measurements on a TN cell, optimizing the measurement interval to prevent missed detections or excessive frequency of measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the measurement interval is excessively long, then the terminal device may not discover the TN cell in time, but if the measurement interval is excessively short, then the terminal device performs measurements frequently resulting in low transmission performance
Solution Approach 1:
The patent applies dynamics by making the measurement interval adjustable rather than fixed. The network device configures multiple measurement intervals (first measurement interval and second measurement interval) and the terminal device dynamically switches between them based on whether a TN cell is detected. This dynamic adjustment resolves the contradiction by adapting the measurement frequency to actual network conditions, ensuring reliable TN cell discovery while avoiding excessive measurements that would degrade transmission performance.
Solution Approach 2:
The patent implements parameter changes by modifying the measurement interval parameter based on detection results. When no TN cell is detected, a first (longer) measurement interval is used to maintain transmission performance. When a TN cell is detected, a second (shorter) measurement interval is applied to ensure timely discovery and handover. This parameter adaptation resolves the technical contradiction by optimizing the measurement interval according to real-time network status.
2Reliability
If the terminal device performs frequent measurements to ensure timely TN cell discovery, then detection reliability improves, but transmission performance deteriorates due to excessive measurements
Solution Approach 1:
The patent uses dynamics to switch measurement frequencies based on detection state. The terminal device maintains low measurement frequency (first measurement interval) during normal operation to preserve transmission performance, and switches to high measurement frequency (second measurement interval) only when TN cell detection is required. This dynamic behavior ensures timely detection when needed while minimizing energy loss during normal transmission.
Solution Approach 2:
The patent changes the measurement interval parameter from a fixed value to a conditional value. The network device configures two different measurement interval parameters, and the terminal device selects appropriate parameters based on whether TN cell detection is triggered. This parameter change strategy resolves the contradiction by ensuring detection reliability only when necessary, thereby avoiding unnecessary energy loss.
3Productivity
If the measurement interval is extended to improve transmission performance, then energy efficiency improves, but TN cell discovery reliability deteriorates
Solution Approach 1:
The patent applies dynamics by implementing a dual measurement interval mechanism. The terminal device uses a first measurement interval (longer duration) for normal operation to maintain transmission performance, and switches to a second measurement interval (shorter duration) when TN cell discovery is needed. This dynamic switching resolves the contradiction by extending the measurement interval only when transmission performance is the priority, while maintaining short intervals when discovery reliability is critical.
4Device complexity
If the terminal device uses a fixed measurement interval, then device complexity is reduced, but adaptability to different network conditions deteriorates
Solution Approach 1:
The patent implements dynamics by enabling the terminal device to adaptively switch between different measurement intervals based on network conditions. The device receives configuration information from the network device that includes multiple measurement interval options and selection criteria. This dynamic adaptation resolves the contradiction by allowing the system to adjust measurement behavior to match actual network scenarios while maintaining relatively simple device architecture.
