Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing D2D/V2X technologies fail to guarantee adaptability between data and transmission resources due to inadequate selection methods.
Innovation Solution
A method for selecting transmission resources and data based on attribute configurations, including Hybrid Automatic Repeat reQuest (HARQ) and association relationships, to ensure compatibility and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal selects transmission resources randomly from a resource pool, then the resource selection process is simple, but the adaptability between data and transmission resource cannot be guaranteed
Solution Approach 1:
The patent divides the resource pool into multiple resource sets, where each resource set is associated with specific data characteristics (such as QoS requirements, data priority, or data type). The terminal selects resources from a specific resource set based on the characteristics of the data to be transmitted, rather than randomly selecting from the entire resource pool. This local differentiation ensures that the selected resources are adapted to the specific data requirements while maintaining a manageable selection process.
Solution Approach 2:
The patent enables dynamic resource set association, where the mapping between data characteristics and resource sets can be flexibly configured and adjusted. The terminal dynamically selects which resource set to use based on the current data transmission requirements, allowing the system to adapt to varying data characteristics without requiring a complete redesign of the resource selection mechanism.
2Adaptability or versatility
If transmission resources are allocated by base station, then resource allocation is centralized and controlled, but the system flexibility and terminal autonomy are reduced
Solution Approach 1:
The patent enables terminals to autonomously select transmission resources from pre-configured resource sets based on their own data characteristics and transmission requirements. The base station provides the resource pool configuration and associations, but the actual resource selection is performed independently by each terminal according to its specific needs, enhancing terminal autonomy and system flexibility while maintaining operational simplicity through pre-established resource set associations.
