Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sidelink communication systems in 3GPP 5G networks lack efficient mechanisms for power management, particularly for power-constrained user equipment (UEs) that need to monitor resources for multiple types of periodic traffic, leading to increased power consumption and potential collisions due to the use of a single Y value for different sensing windows.
Innovation Solution
The implementation of multiple Y values and K values for different types of periodic traffic and transmission types within a resource pool, allowing UEs to configure specific sensing occasions and resource selection based on varying traffic periods and types, thereby optimizing power usage and reducing collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single Y value is used for sensing window configuration in sidelink communication, then the system complexity is reduced and configuration is simplified, but power consumption increases for power-constrained UEs monitoring multiple types of periodic traffic
Solution Approach 1:
The patent segments the sensing window configuration by introducing multiple Y values (Y1, Y2, etc.) corresponding to different traffic types or transmission types. Each Y value configures a specific sensing window size for particular traffic patterns, allowing UEs to selectively monitor only relevant resources for their specific traffic requirements rather than monitoring all resources, thereby reducing power consumption while maintaining manageable system complexity through structured configuration.
Solution Approach 2:
The patent enables dynamic sensing window adaptation by configuring different Y values for different traffic types. UEs can dynamically adjust their sensing window size based on the specific traffic type being monitored, allowing the system to optimize power consumption for each traffic pattern while maintaining flexibility in resource allocation and collision avoidance strategies.
2Device complexity
If a single Y value is used for all periodic traffic types, then resource pool management is simplified, but resource selection accuracy decreases leading to potential collisions
Solution Approach 1:
The patent applies local quality by configuring specific Y values for specific traffic types or transmission types within the resource pool. Each traffic type receives a tailored sensing window size optimized for its characteristics, improving resource selection accuracy for each local context while maintaining overall resource pool management through centralized configuration of multiple Y values.
Solution Approach 2:
The patent changes the sensing window parameter (Y value) based on traffic type and transmission type. By adjusting the Y parameter dynamically according to specific traffic requirements, the system achieves higher resource selection accuracy for mixed traffic patterns while managing complexity through parameter-based configuration rather than structural changes.
3Use of energy by moving object
If multiple Y values are configured for different traffic types, then power efficiency is improved and resource selection accuracy is enhanced, but configuration complexity increases
Solution Approach 1:
The patent achieves universality by designing a multi-functional Y value configuration system where multiple Y values serve different traffic types and transmission types within a unified resource pool framework. This universal approach allows a single configuration mechanism to handle diverse traffic patterns efficiently, improving power efficiency and resource selection accuracy while managing complexity through standardized multi-functional configuration procedures.
