V2X Resource Selection via Sensing-Permitted Random Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Vehicle to Everything (V2X) systems, the processing time required for sensing available resources can lead to terminals selecting transmission resources from an exceptional resource pool, increasing spectrum fragments and reducing the overall amount of available resources.
Innovation Solution
A method and terminal that sense available resources in a current resource pool and determine if random selection of a transmission resource is permitted before acquiring a sensing result, allowing for random selection from the current pool without configuring an additional exceptional resource pool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If terminals randomly select transmission resources from a pre-configured exceptional resource pool when sensing is not finished, then data transmission can proceed before sensing completion, but spectrum fragments increase and the overall amount of available resources decreases
Solution Approach 1:
The patent merges the exceptional resource pool with the current resource pool, allowing terminals to select resources from the same pool regardless of sensing completion status. This eliminates the need for separate exceptional resources and prevents spectrum fragmentation, resolving the contradiction between fast data transmission and maintaining sufficient available resources.
2Adaptability or versatility
If an additional exceptional resource pool is configured for urgent data transmission, then terminals can transmit data before sensing completion, but device complexity increases and resource utilization decreases
Solution Approach 1:
The patent makes the current resource pool universal by allowing both sensing-based selection and random selection from the same pool. This eliminates the need for separate exceptional resource pool configuration, reducing system complexity while maintaining transmission flexibility through the same resource pool.

AI summary
A method and a terminal for acquiring a transmission resource in vehicle to everything are provided. In the implementations of the present disclosure, available resources in a current resource pool are sensed, and if the terminal needs to send data before a sensing result is acquired, whether the current resource pool permits random selection of a transmission resource is determined, if the current resource pool permits the random selection of a transmission resources, a transmission resource is randomly selected from the current resource pool.
