Inter-UE Coordination for Non-Preferred Resource Pool Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing resource conflicts and optimizing resource allocation for reference signals and control information in high-density and high-frequency environments, such as those anticipated in 6G networks, which can lead to interference and reduced performance.
Innovation Solution
A method and device for performing wireless communication that involves identifying and managing resource conflicts by creating non-preferred resource sets within dedicated and shared resource pools, and transmitting coordination messages to user equipment (UE) to optimize resource usage, utilizing a one-to-one correspondence between resource pools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resource pools are shared between control information and reference signals, then resource utilization efficiency is improved, but resource conflicts and interference increase
Solution Approach 1:
The resource pool is segmented into preferred and non-preferred resource sets for both control information and reference signals. This segmentation allows the system to identify and separate conflicting resources while maintaining overall resource sharing, thus improving utilization efficiency while reducing interference through structured resource allocation.
Solution Approach 2:
The patent introduces coordination messages as an intermediary mechanism between UEs. These messages convey information about non-preferred resource sets, allowing UEs to adjust their resource selection and avoid conflicts without direct interference, thus resolving the contradiction between resource sharing and interference reduction.
2Quantity of substance
If resource allocation is optimized for high-density networks, then system capacity is improved, but resource conflict management complexity increases
Solution Approach 1:
The patent performs preliminary identification and classification of non-preferred resources before actual transmission. By pre-defining non-preferred resource sets and sharing this information through coordination messages, the system simplifies real-time conflict management while supporting high-density network operations, thus increasing capacity without proportionally increasing management complexity.
Solution Approach 2:
Each UE autonomously determines and manages its own non-preferred resource sets based on local measurements and coordination messages from other UEs. This self-service approach allows the system to scale to high density without requiring centralized control, thereby increasing system capacity while keeping individual device complexity manageable.

AI summary
An operation method of a first device 100 in wireless communication system is proposed. The method may comprise: including at least one second resource in a second resource pool, corresponding to at least one first resource in which a conflict in a first resource pool is expected, into a first non-preferred resource set for a first reference signal; including at least one fourth resource in the first resource pool, corresponding to at least one third resource in which a conflict in the second resource pool is expected, into a second non-preferred resource set for first control information; and transmitting on the first resource pool, to a second device 200, an inter UE coordination message, including information for the first non-preferred resource set and information for the second non-preferred resource set.
