Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IoV systems lack a method for terminal-to-terminal data transmission using multiple carriers, which is essential for enhancing spectral efficiency and reducing transmission delay in direct communication modes.
Innovation Solution
A terminal determines and sends first service data on multiple carriers to a network device, allowing the network device to allocate transmission resources based on the data volume, enabling terminal-to-terminal data transmission in IoV systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminal-to-terminal data transmission is implemented in an IoV system, then spectral efficiency is improved and transmission delay is reduced, but the method for performing such transmission on multiple carriers is not established
Solution Approach 1:
The patent segments the data transmission process into distinct phases: determining carriers to be used, determining data volumes on each carrier, and reporting this information to the network device. This segmentation allows the complex multi-carrier transmission to be managed through systematic, step-by-step procedures defined in the standard
Solution Approach 2:
The patent applies preliminary action by requiring the terminal to determine and report carrier selections and data volumes before actual data transmission occurs. The network device uses this advance information to allocate resources appropriately, enabling efficient multi-carrier transmission without ad-hoc decision-making during transmission
2Loss of time
If terminal-to-terminal data transmission is implemented in an IoV system, then transmission delay is reduced, but the mechanism for resource allocation on multiple carriers is not defined
Solution Approach 1:
The patent implements feedback by having the terminal report carrier determination results and data volume information to the network device. This feedback loop enables the network device to make informed resource allocation decisions, balancing the need for low latency with the complexity of managing multiple carriers
Solution Approach 2:
The network device acts as an intermediary that receives carrier and data volume information from the terminal, processes this information, and allocates resources accordingly. This intermediary role simplifies the overall system by centralizing the complex resource allocation logic in the network device rather than requiring complex distributed decision-making
