Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in configuring Discontinuous Reception (DRX) cycles for Low-Earth Orbit (LEO) cells, leading to power consumption issues and measurement inefficiencies due to varying cell mobility and movement.
Innovation Solution
Introduce a DRX cycle threshold as the highest value that can support LEO cell measurement, allowing UEs to determine or receive an appropriate DRX cycle for LEO cell measurement, thereby optimizing power consumption and measurement efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If DRX cycle is extended to reduce power consumption, then power saving is improved, but LEO cell measurement capability deteriorates
Solution Approach 1:
The patent introduces a DRX cycle threshold parameter that changes the operational parameters of the UE based on the type of cell being measured. When measuring LEO cells, the UE is configured with a specific DRX cycle threshold that allows extended DRX cycles for power saving while ensuring measurement capability is maintained through this parameter-based control mechanism
Solution Approach 2:
The patent implements dynamic DRX cycle configuration where the UE can adapt its DRX cycle based on the detected cell type. The system dynamically adjusts the DRX cycle length - using longer cycles for power saving in LEO cell measurements while falling back to shorter cycles when measurement capabilities are compromised, creating a dynamic balance between power consumption and measurement accuracy
2Measurement precision
If DRX cycle is shortened to improve measurement accuracy, then measurement capability is improved, but power consumption increases
Solution Approach 1:
The patent uses parameter changes by introducing a DRX cycle threshold that allows the system to select appropriate DRX cycle lengths based on measurement requirements. This parameter mechanism enables the UE to use shorter DRX cycles when measurement accuracy is critical and longer cycles when power saving is the priority, optimizing the trade-off dynamically
3Use of energy by moving object
If UE determines DRX cycle based on DRX cycle threshold, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the UE to autonomously determine its own DRX cycle based on the DRX cycle threshold and detected cell type. The UE independently makes decisions about DRX configuration without requiring complex network coordination or manual configuration, reducing the operational complexity burden on the network side while maintaining power efficiency
Solution Approach 2:
The patent applies segmentation by dividing the DRX cycle determination process into distinct logical steps: detecting cell type, comparing against DRX cycle threshold, and selecting appropriate cycle length. This segmented approach simplifies the overall complexity by breaking down the decision-making process into manageable, sequential operations rather than a single complex algorithm
