V2X Terminal Carrier Reselection for Multi-Process Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing V2X system's carrier selection method is not adapted to scenarios where a terminal selects a carrier from multiple carriers, leading to inefficiencies and resource conflicts, particularly in scenarios requiring resource reselection.
Innovation Solution
A method and terminal device that allow for independent carrier reselection for each process running on multiple carriers, using various triggering manners such as resource reselection timers, pool configuration, data size considerations, and priority-based selection to optimize carrier usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal adopts a semi-persistent transmission manner on a single carrier, then resource reselection probability and resource conflict are reduced, but adaptability to multiple application scenarios and multi-carrier scenarios is insufficient
Solution Approach 1:
The patent divides the single carrier selection into multiple independent carrier selections, one for each process. Each process can independently select and reselect carriers based on its own needs, enabling multi-carrier operation while maintaining the benefits of semi-persistent transmission within each process
Solution Approach 2:
The patent introduces dynamic carrier reselection mechanisms where carriers can be reselected based on triggering conditions such as resource reselection timers, pool configuration changes, data size requirements, and priority levels. This dynamic approach allows the system to adapt to changing conditions while maintaining stable operation during normal periods
2Ease of operation
If a terminal randomly selects a resource from an available transmission resource set, then resource allocation is simple, but resource conflicts occur frequently in multi-carrier scenarios
Solution Approach 1:
The patent segments the resource selection process by process, where each process independently selects carriers and resources. This segmentation reduces conflicts by distributing resource usage across multiple carriers and processes, while each individual selection remains relatively simple
Solution Approach 2:
The patent changes the selection parameters by introducing carrier-specific criteria including resource reselection timers, pool configuration parameters, data size thresholds, and priority levels. These parameter changes enable more informed resource selection that reduces conflicts while maintaining operational simplicity through standardized evaluation criteria
3Loss of time
If a terminal uses the same transmission resource in multiple transmission cycles, then resource reselection probability is reduced, but the system cannot adapt to changing channel conditions and different process requirements
Solution Approach 1:
The patent introduces dynamic carrier reselection capabilities where each process can reselect carriers based on triggering conditions such as resource reselection timers, pool configuration changes, data size requirements, and priority levels. This allows the system to maintain stable resource usage during normal operation while adapting to changing conditions when necessary
Solution Approach 2:
The patent establishes preliminary carrier selections for each process that can be maintained over multiple transmission cycles, reducing the frequency of reselection operations. Triggering conditions are pre-defined to determine when reselection should occur, allowing the system to operate efficiently with minimal reselection while remaining adaptable to changes

AI summary
Disclosed is a carrier selection method, a terminal device and a computer storage medium. The method comprises: running at least one process on at least one initial carrier, wherein different processes are run on the same or different initial carriers; selecting a first carrier for a target process in the at least one process, wherein the first carrier is the same as or different from the initial carrier; and bearing at least a part of data of the target process on the first carrier.
