Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inter-UE coordination mechanisms in wireless communication systems face accuracy issues due to uniform RSRP threshold settings and UE capability considerations, leading to reduced availability of resources and inaccurate resource conflict determination.
Innovation Solution
A method for determining inter-UE coordination information based on customized configuration conditions for each UE, including specific RSRP thresholds and resource exclusion criteria, to enhance the accuracy of preferred resource selection and conflict detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a specific resource is excluded from the preferred resource based on UE capability (e.g., half duplex) at one time in determining the preferred resource, then the resource selection process is simplified, but available resources become short and the accuracy of inter-UE coordination information is lowered
Solution Approach 1:
The patent divides the resource exclusion process into multiple stages: first excluding resources based on half-duplex constraints, then separately excluding resources based on resource collision information from other UEs. This segmented approach prevents premature over-exclusion while maintaining process simplicity, thereby preserving both available resources and coordination accuracy.
Solution Approach 2:
The patent implements dynamic resource exclusion by adjusting the exclusion criteria based on current system conditions. The UE dynamically determines which resources to exclude based on real-time resource collision information and coordination messages from other UEs, rather than applying static exclusion rules that would overly restrict available resources.
2Ease of operation
If one value unified at one time is used as an RSRP threshold for determining the conflict of the reserved resource without a detailed configuration for each UE, then the system operation is simplified, but the RSRP measurement capability of the UE which generates the inter-UE coordination information is not sufficiently considered and the accuracy is lowered
Solution Approach 1:
The patent applies local quality by allowing each UE to use its own RSRP measurement capability characteristics when determining resource conflicts. Instead of a uniform threshold for all UEs, each UE applies the RSRP threshold according to its specific measurement capabilities, thereby achieving accurate resource conflict determination tailored to individual UE performance.
Solution Approach 2:
The patent changes the RSRP threshold parameter based on UE-specific measurement capabilities. The system configures different RSRP thresholds for different UEs according to their measurement capabilities, allowing the parameter to adapt to individual UE characteristics while maintaining systematic operation.
3Ease of manufacture
If uniform resource exclusion criteria are applied to all UEs in inter-UE coordination, then the coordination mechanism is easier to implement, but the accuracy of coordination information varies across different UE capabilities and scenarios
Solution Approach 1:
The patent modifies the resource exclusion parameters based on UE-specific capabilities and conditions. Each UE determines its resource exclusion criteria by considering its own half-duplex status, resource collision information, and RSRP measurement capabilities, thereby achieving reliable coordination information adapted to individual UE characteristics while maintaining a systematic implementation framework.

AI summary
According to an embodiment of the present disclosure, a method of a first User Equipment (UE) for transmitting information related to an Inter-UE Coordination in a wireless communication system includes: determining information related to an Inter-UE Coordination based on configuration information, and transmitting, to a second UE, the information related to the Inter-UE Coordination. The information related to the Inter-UE Coordination is based on information representing a preferred resource or information representing a conflict of a reserved resource. Based on information for a first condition included in the configuration information, the preferred resource is determined among the resources related to the transmission of the second UE. Based on the information for the second condition included in the configuration information, an RSRP threshold related to the RSRP measured by the first UE is determined.
