V2X Link Scheduling by UL-SL Priority Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X communication mechanisms fail to balance data transmission requirements such as latency and reliability on both SL and UL, and do not resolve transmission conflicts between services on different links.
Innovation Solution
A communication method that prioritizes UL or SL transmission based on parameter values such as PPPP or priority levels, allowing for accurate determination of transmission priorities by comparing parameter values to determine whether UL or SL MAC PDUs are preferentially transmitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If device-side autonomous actions are introduced to improve responsiveness, then user experience is improved, but device complexity increases
Solution Approach 1:
The patent segments autonomous actions into distinct types (initiated vs. triggered) with different authorization requirements. Initiated actions require explicit user authorization, while triggered actions operate with implicit authorization based on predefined conditions. This segmentation allows the system to implement autonomous functionality without requiring complex authorization logic for every action.
Solution Approach 2:
The system performs preliminary authorization setup by defining authorized triggered actions and their conditions in advance. Users configure which actions should be automatically triggered and under what conditions, rather than authorizing each action in real-time. This preliminary configuration reduces runtime complexity while maintaining user control.
2Speed
If autonomous actions are executed without confirmation, then responsiveness is improved, but user control is reduced
Solution Approach 1:
The patent implements dynamic authorization where the system adapts its confirmation requirements based on the action type and context. High-risk actions require explicit user confirmation, while routine actions can execute automatically based on predefined conditions. This dynamic approach allows responsiveness to be optimized for appropriate actions while maintaining user control for critical operations.
Solution Approach 2:
The system provides feedback mechanisms that inform users about triggered actions and their outcomes. Users can review logs of automatic actions and adjust their authorization preferences based on observed system behavior. This feedback loop maintains user control while enabling autonomous execution for appropriate actions.

AI summary
This application provides a communication method and a related device that are related to data transmission in vehicle-to-everything. The method includes: A terminal device obtains a first parameter value of an uplink and a second parameter value of a sidelink; and the terminal device determines, based on a comparison between the first parameter value and the second parameter value, to transmit to-be-transmitted uplink data or to-be-transmitted sidelink data. Through implementation of this method, a vehicle-mounted terminal device in the vehicle-to-everything can better satisfy uplink and sidelink transmission requirements.
