Sidelink Inter-UE Coordination Using Designated Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently coordinating sidelink inter-user equipment (UE) communications due to the lack of designated resources, leading to increased latency and resource conflicts.
Innovation Solution
The method involves identifying and designating specific resources within a sidelink resource pool configuration for sidelink inter-UE coordination information, allowing for direct communication between UEs without relying on base station intermediaries, thereby reducing latency and resource conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If designated resources are allocated for sidelink inter-UE coordination information, then communication efficiency is improved and latency is reduced, but resource pool complexity increases
Solution Approach 1:
The resource pool is segmented into specific designated resources for inter-UE coordination information, separating coordination traffic from regular data traffic. This segmentation allows efficient coordination communication while maintaining organized resource management through clear resource allocation patterns defined in the resource pool configuration.
2Loss of time
If direct UE-to-UE communication is enabled without base station intermediaries, then latency is reduced and autonomy is improved, but resource conflict probability increases
Solution Approach 1:
Resources for inter-UE coordination are pre-configured and designated in advance through resource pool configuration. This preliminary allocation of specific time-frequency resources for coordination information ensures that UEs have predetermined conflict-free resources available, eliminating the need for dynamic resource negotiation and reducing resource conflicts while enabling direct communication.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a set of resources that are designated for sidelink inter-UE coordination information based at least in part on a sidelink resource pool configuration. The UE may transmit or monitor for a communication that includes inter-UE coordination information in a resource of the set of resources. Numerous other aspects are described.
