Sidelink IDC Interference Indication via Scheduling Request
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies struggle to effectively indicate In Device Coexistence (IDC) interference on sidelinks, which differs from IDC interference on the Uu interface due to differing usage patterns of uplink carriers for transmission and reception.
Innovation Solution
A communication processing method and device that allow User Equipment (UE) to report IDC interference indication information when interference is detected, specifically indicating affected transmission links that include sidelinks, cellular communication links, or satellite communication links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the uplink carrier is shared between sidelink and Uu interface based on frequency division multiplexing, then resource utilization is improved, but interference management becomes complex and difficult to distinguish
Solution Approach 1:
The patent segments the interference indication by introducing a specific indication bit in the scheduling request message to distinguish sidelink interference from Uu interface interference. This segmentation allows the base station to identify the source of interference and apply appropriate interference management strategies for each link type, resolving the complexity while maintaining resource sharing.
2Adaptability or versatility
If the UE uses the uplink carrier for both transmission and reception on sidelink, then communication flexibility is improved, but interference patterns become unpredictable and difficult to manage
Solution Approach 1:
The patent implements a feedback mechanism where the UE reports sidelink interference status to the base station through scheduling request messages. This feedback loop allows the base station to adapt resource allocation and transmission parameters based on actual interference conditions, maintaining reliability while preserving communication flexibility on the sidelink.
3Loss of information
If IDC interference indication is not specifically provided for sidelink, then signaling overhead is reduced, but interference mitigation effectiveness deteriorates
Solution Approach 1:
The patent applies partial action by adding a specific indication bit in the scheduling request message rather than creating a completely separate reporting mechanism. This minimal addition provides the necessary sidelink interference information to the base station without significantly increasing signaling overhead, thus maintaining interference mitigation effectiveness while keeping overhead low.
