Sidelink SCI Format 2-C Resource Indication for Inter-UE Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently determining and indicating resources for inter-user equipment (UE) coordination in sidelink communication, particularly in configuring and managing resource allocation between UEs.
Innovation Solution
A method is provided where user equipment (UE) receives first coordination information, which includes a starting slot and multiple resource indication combinations, allowing flexible indication of a resource location within a coordination resource window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional resource indication methods are used in sidelink communication, then the coordination between UEs can be maintained, but the resource indication efficiency is low and cannot flexibly indicate resources in any slot
Solution Approach 1:
The patent applies dynamics by making the resource indication method adjustable and flexible through multiple indication modes (direct indication, offset indication, combination indication). The system can dynamically select different indication methods based on the coordination resource window size and resource distribution patterns, transforming a static indication approach into a dynamic one that adapts to different scenarios.
Solution Approach 2:
The patent changes parameters by introducing configurable indication parameters such as offset values, resource indication combinations (RIC), and reference slot configurations. These parameters can be adjusted according to the specific coordination requirements and resource pool characteristics, enabling flexible indication of resources across different slots while maintaining efficient signaling.
2Productivity
If resource allocation coordination is implemented between multiple UEs, then resource allocation efficiency improves, but the complexity of determining and managing coordination resources increases
Solution Approach 1:
The patent uses an intermediary approach by introducing a standardized coordination information structure that includes reference slot configurations and offset parameters. This intermediary framework mediates between multiple UEs, providing a common language and methodology for resource indication that simplifies the coordination process while maintaining allocation efficiency.
Solution Approach 2:
The patent applies segmentation by dividing the resource indication process into distinct components: reference slot identification, offset calculation, and resource determination. This segmentation allows each component to be handled independently with specific algorithms, reducing the overall complexity of coordination resource management while improving efficiency.
