Solution Overview

Problem

In New Radio (NR) systems, the large coverage area of satellites results in significant differences in signal transmission delays between terminal devices and satellite base stations, making traditional neighboring cell measurement methods ineffective, leading to data transmission interruptions and poor user experience.

Innovation Solution

Configuring at least two sets of measurement gap configurations for terminal devices, each tailored to different signal transmission delay ranges, allowing for efficient neighboring cell measurement without prolonging data transmission interruptions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single measurement gap configuration is used for satellite communication, then the measurement can cover all neighboring cells, but the data transmission time is continuously interrupted for the entire measurement duration

Engineering Contradiction:
Improveneighboring cell measurement coverageVSAvoiddata transmission interruption duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent divides the measurement gap configuration into multiple sets, where each set corresponds to different signal transmission delay ranges. The terminal device selects and applies only the relevant measurement gap configuration set for the current measurement scenario, thereby segmenting the measurement process to minimize data transmission interruption while ensuring comprehensive coverage of neighboring cells with varying delay characteristics

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic selection of measurement gap configuration sets based on the terminal device's current state and the neighboring cell's signal transmission delay characteristics. The network device dynamically determines which configuration set to apply, allowing the measurement gap duration to be adjusted according to actual measurement needs, thus reducing unnecessary data transmission interruptions

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the measurement gap duration is prolonged to cover satellite neighboring cells with large transmission delay differences, then all neighboring cells can be measured, but the serving cell's data transmission is interrupted for longer periods

Engineering Contradiction:
Improvemeasurement coverage for different transmission delay rangesVSAvoiddata transmission efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the measurement gap configurations into multiple sets, each tailored for specific signal transmission delay ranges. The terminal device and network device work together to select the appropriate configuration set based on the actual measurement scenario, ensuring that only the necessary measurement duration is applied, thereby maintaining data transmission efficiency while covering diverse neighboring cells

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by customizing measurement gap configuration parameters (such as duration and timing) according to the specific characteristics of different neighboring cells and their transmission delay ranges. This localized optimization ensures that each measurement scenario receives the precise configuration needed, avoiding excessive measurement gaps that would disrupt data transmission

Inventive Principle:
Principle #3Local quality
