Sidelink Resource Coordination via Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sidelink communication, especially in scenarios like autonomous vehicles, there is a risk of radio resource conflicts due to congestion, particularly when the base station does not explicitly schedule radio resources, leading to inefficiencies in high-rate and large-capacity data processing requirements.
Innovation Solution
A method for UE to perform sidelink communication by transmitting and receiving sidelink control information that includes request information for coordination and indication of resource types, using this information to determine suitable resources for communication based on coordination information and resource sensing data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If UEs autonomously select radio resources for sidelink communication without base station scheduling, then communication flexibility and autonomy are improved, but resource conflicts and congestion increase
Solution Approach 1:
The patent implements a feedback mechanism where UEs exchange coordination information including resource sensing results and selected resource indicators. This feedback loop allows UEs to adjust their resource selections based on actual channel conditions and other UEs' selections, reducing conflicts while maintaining autonomous operation. The coordination information acts as feedback that refines resource allocation decisions.
Solution Approach 2:
The patent introduces coordination information as an intermediary mechanism between UEs. This intermediary contains resource sensing results, selected resource indicators, and other relevant data that mediate the resource selection process. Instead of direct conflict between autonomous UEs, the coordination information serves as a mediator that facilitates coordinated resource selection and reduces conflicts.
2Reliability
If coordination information is exchanged between UEs to reduce resource conflicts, then resource allocation reliability is improved, but communication overhead and complexity increase
Solution Approach 1:
The patent segments the coordination information into distinct components: resource sensing results, selected resource indicators, and other relevant parameters. This segmentation allows each component to be processed independently and simplifies the overall coordination protocol. UEs can selectively exchange only the necessary segments based on their specific needs, reducing overall complexity.
Solution Approach 2:
The patent enables UEs to self-configure their resource selections based on the received coordination information without requiring complex centralized control. Each UE autonomously processes the coordination information and makes its own resource selection decisions, reducing the complexity of inter-UE coordination while maintaining high reliability through distributed intelligence.
