Wireless Node Indexing for Unicast V2X Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE V2X systems are limited to broadcast transmission, which results in low resource utilization and unreliable data transmission, especially for big-packet services, necessitating the introduction of unicast transmission to enhance spectrum efficiency and transmission performance in Vehicle-to-Everything (V2X) communications.
Innovation Solution
A method for wireless communication that includes transmitting a target radio signal with Q index groups and first signaling, where the first signaling configures a first radio signal using a unique second-type index, allowing for unicast transmission by uniquely identifying terminals and improving data channel reception complexity and spectrum efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If broadcast transmission is used in LTE V2X systems, then system simplicity is maintained, but resource utilization is low and transmission reliability is poor
Solution Approach 1:
The patent segments the broadcast transmission approach into multiple unicast transmission streams, where each stream is dedicated to a specific terminal. This segmentation allows the system to maintain reliability through targeted transmissions while managing complexity through structured resource allocation and indexing mechanisms.
Solution Approach 2:
The patent changes the transmission parameter from broadcast mode to unicast mode, fundamentally altering how data is transmitted. By introducing configurable parameters such as Q index groups, first-type indexes, and second-type indexes, the system can dynamically adjust transmission characteristics to achieve both high reliability and controlled complexity.
2Productivity
If unicast transmission is introduced to improve resource utilization, then spectrum efficiency improves, but system complexity increases
Solution Approach 1:
The patent creates a universal indexing mechanism that can handle multiple terminals through a standardized structure. The Q index groups, first-type indexes, and second-type indexes form a multi-functional framework that can accommodate any number of unicast transmissions using the same systematic approach, thereby improving spectrum efficiency without proportionally increasing complexity.
Solution Approach 2:
The patent introduces index structures as intermediaries between the transmitter and multiple receivers. These indexes act as mediators that organize and identify different unicast streams, allowing the system to manage multiple simultaneous transmissions efficiently. The indexing mechanism simplifies the complexity by providing a structured way to handle what would otherwise be chaotic multi-terminal communications.
3Reliability
If broadcast transmission is used, then system operation is simple, but data transmission reliability for specific terminals cannot be guaranteed
Solution Approach 1:
The patent introduces dynamic terminal identification through indexing mechanisms. Instead of static broadcast transmission, the system dynamically assigns and identifies terminals using Q index groups, first-type indexes, and second-type indexes. This dynamic approach ensures reliable delivery to specific terminals while maintaining operational simplicity through automated index management.
4Measurement precision
If multiple terminals are supported with unique identification, then reception performance improves, but signaling overhead increases
Solution Approach 1:
The patent employs a nested indexing structure where Q index groups contain multiple first-type indexes, and each first-type index is associated with second-type indexes. This nested organization allows precise terminal identification through hierarchical indexing, reducing the overall signaling overhead by efficiently packing identification information in a structured manner rather than using separate explicit identifiers for each terminal.
