Sidelink Resource Reallocation for IDC Interference Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face the challenge of In Device Coexistence (IDC) interference in sidelink communication modes where UEs autonomously select resources, with no effective solutions currently available to address this issue.
Innovation Solution
A communication processing method where UEs or base stations exchange IDC interference indication information to re-determine or re-allocate transmitting resources, utilizing TDM and FDM auxiliary information to mitigate interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a UE autonomously selects resources for sidelink transmission, then resource allocation flexibility is improved, but IDC interference cannot be resolved
Solution Approach 1:
The patent implements a feedback mechanism where the first UE reports IDC interference indication information to the second UE or base station, and the second UE or base station responds by re-determining transmitting resources. This closed-loop feedback system enables dynamic adaptation to IDC interference while preserving autonomous resource selection flexibility.
Solution Approach 2:
The patent introduces an intermediary mechanism where IDC interference indication information serves as a mediator between the first UE and the second UE/base station. This intermediary information enables coordination and resource re-allocation without requiring direct intervention in the autonomous resource selection process.
2Ease of manufacture
If transmitting resource pools are pre-configured for autonomous sidelink communication, then setup simplicity is improved, but interference resolution capability deteriorates
Solution Approach 1:
The patent transforms the static pre-configured resource pool into a dynamic system by introducing real-time IDC interference indication reporting and resource re-determination. The resource allocation remains simple to set up but becomes adaptable through dynamic adjustments based on interference conditions.
Solution Approach 2:
The patent changes the parameter state of resource allocation from fixed pre-configured values to dynamically adjustable values based on IDC interference indication information. This allows the system to maintain simple setup while adapting resource parameters in response to interference conditions.
3Device complexity
If no IDC interference solution is implemented, then device complexity is reduced, but communication reliability deteriorates
Solution Approach 1:
The patent implements a self-service mechanism where the first UE autonomously detects and reports IDC interference conditions, and the second UE or base station autonomously determines appropriate resource re-allocations. This self-service approach improves communication reliability without requiring complex external interference resolution systems.
