V2X Terminal Resource Conflict Resolution via Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of resource conflicts arising from overlapping transmission resources on different communications links in complex data transmission scenarios, such as those involving cellular and sidelink communications, is not adequately addressed by existing technologies.
Innovation Solution
A communication method where a terminal apparatus prioritizes transmission or reception on a higher-priority link by canceling conflicting lower-priority operations on overlapping resources, ensuring that critical data is transmitted or received without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal apparatus receives/transmits data on multiple communications links simultaneously, then the communication capability and data transmission flexibility are improved, but resource conflicts occur when transmission resources overlap
Solution Approach 1:
The patent changes the parameter of resource allocation by introducing priority levels for different communications links. The network device configures priority information for each link, and the terminal apparatus uses these priority parameters to resolve resource conflicts by selecting higher-priority links when resource overlaps occur, thereby maintaining reliable communication without sacrificing multi-link capability
Solution Approach 2:
The patent implements dynamic resource allocation by allowing the terminal apparatus to adaptively select which link to use based on real-time priority comparisons. When resource conflicts are detected, the system dynamically adjusts resource usage by canceling lower-priority transmissions and maintaining higher-priority ones, enabling flexible response to changing communication conditions
2Reliability
If the terminal apparatus prioritizes higher-priority data transmission by canceling lower-priority operations, then resource conflict is resolved and transmission reliability is improved, but some data transmission may be lost or delayed
Solution Approach 1:
The patent changes the parameter of resource allocation by introducing priority levels for different communications links. The network device configures priority information for each link, and the terminal apparatus uses these priority parameters to resolve resource conflicts by selecting higher-priority links when resource overlaps occur
Solution Approach 2:
The patent implements dynamic resource allocation by allowing the terminal apparatus to adaptively select which link to use based on real-time priority comparisons. When resource conflicts are detected, the system dynamically adjusts resource usage by canceling lower-priority transmissions and maintaining higher-priority ones

AI summary
The present invention provides a communication method and an apparatus, applied to the internet of vehicles, for example, V2X or LTE-V. A terminal apparatus obtains first indication information, where the first indication information is used to indicate a first time domain resource to be used by the terminal apparatus to send or receive first information on a first link. The terminal apparatus obtains second indication information, where the second indication information is used to indicate a second time domain resource to be used by the terminal apparatus to send or receive second information on a second link. When the first time domain resource overlaps with the second time domain resource, the terminal apparatus sends or receives the first information on the first time domain resource, and/or cancels receiving or sending of the second information on the second time domain resource. Alternatively, when the first time domain resource overlaps with a third time domain resource, the terminal apparatus sends or receives the first information on the first time domain resource, and/or cancels receiving or sending of the second information on the second time domain resource, where an end time point of the third time domain resource is a start time point of the second time domain resource.
