V2X Resource Sensing Reports with No-Traffic State Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of vehicle-to-everything (V2X) wireless communication, overlapping resource pools from dynamically scheduled and autonomously selected resources can cause collisions, leading to incorrect determination of UE states by base stations.
Innovation Solution
UEs determine whether a service is in progress and add specified identifiers to resource sensing messages when no service is ongoing, indicating this state, to prevent incorrect base station determinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resource pools of dynamically scheduled and autonomously selected schemes are overlapped, then resource utilization flexibility is improved, but collision between resources occurs leading to incorrect UE state determination
Solution Approach 1:
A specific identifier (value 1) is introduced as an intermediary element in the resource sensing message to clearly distinguish between different resource allocation states. This identifier acts as a mediator that helps the base station correctly interpret the UE's resource usage status, preventing misjudgment caused by overlapping resource pools while maintaining the flexibility of both dynamic scheduling and autonomous selection schemes.
2Productivity
If UE autonomously selects resources from resource pool, then scheduling efficiency is improved, but collision with dynamically scheduled resources occurs
Solution Approach 1:
The UE provides feedback to the base station by including a specific identifier (value 1) in the resource sensing message when no service is currently in progress. This feedback mechanism enables the base station to understand the UE's resource availability status, allowing the base station to make informed scheduling decisions that avoid collisions while maintaining high scheduling efficiency through autonomous resource selection.

AI summary
Provided is a method for reporting a resource sensing result that can include determining whether a traffic is currently in progress in response to detecting that a resource sensing result needs to be reported to a base station, and adding a specified identifier to a resource sensing message in response to determining that no traffic is currently in progress. The specified identifier being intended to indicate that no traffic is currently in progress. The method can further include reporting the resource sensing message to the base station.
