UE IDC Reporting With Clean and Non-Clean Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in managing in-device coexistence conflicts between multiple wireless technologies within a single device, leading to inefficiencies and interference.
Innovation Solution
User equipment (UE) and network nodes implement enhanced in-device coexistence (IDC) reporting by exchanging uplink assistance information (UAI) to manage resource allocation and conflicts, including configuring clean and non-clean resources, and utilizing IDC reporting prohibit timers to optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless technologies operate simultaneously in a single device, then device functionality and versatility are improved, but in-device coexistence conflicts and interference increase
Solution Approach 1:
The patent segments radio resources into clean resources and non-clean resources based on IDC conflict identification. The network node receives IDC indication information from the UE, determines which resources are affected by coexistence conflicts, and separately manages these segmented resource sets to avoid interference while maintaining multi-technology functionality.
Solution Approach 2:
The patent introduces an intermediary mechanism where the UE sends IDC indication information to the network node, which then acts as a mediator to adjust resource allocation. The network node uses this information to identify non-clean resources and reconfigure them, mediating between the competing wireless technologies to resolve conflicts.
2Reliability
If traditional IDC reporting methods are used, then basic conflict identification is achieved, but resource management efficiency and system performance are insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the UE continuously monitors for IDC conflicts and sends indication information to the network node. The network node processes this feedback, identifies non-clean resources, and adjusts resource allocation accordingly, creating a closed-loop system that improves resource management efficiency through continuous optimization.
Solution Approach 2:
The patent applies preliminary action by having the network node pre-identify and mark non-clean resources based on UE feedback before conflicts actually occur. The network node determines which resources may be affected by IDC conflicts and proactively manages their allocation, preventing interference before it impacts system performance.

AI summary
A user equipment (UE) may establish a radio resource control (RRC) connection with a network node and receive a RRC reconfiguration message from the network node. The UE may determine, based on the RRC reconfiguration message, at least one of one or more clean resources or one or more non-clean resources, wherein the one or more non-clean resources may correspond to at least one in-device coexistence (IDC) conflict. The UE may transmit uplink assistance information (UAI) to the network node and the UAI may include information corresponding to one or more starting points and one or more ending points of at least one of the one or more clean resources or one or more non-clean resources.
