Idle-State IDC Reporting for Base-Station Interference Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminals experience in-device coexistence interference (IDC) that current solutions fail to address when they are in an idle or inactive state, leading to communication disruptions.
Innovation Solution
The method involves determining IDC in idle or inactive states and sending IDC indication information to the base station, allowing the base station to identify interfering carrier frequencies and provide solutions to ensure communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal only sends IDC indication information to the base station when in connected state, then the device complexity is reduced, but the reliability of communication is worsened because terminals in idle or inactive states cannot report IDC
Solution Approach 1:
The patent enables terminals to send IDC indication information to the base station across all operational states (connected, inactive, and idle states), transforming the IDC reporting mechanism from a state-specific function to a universal capability. This multi-state reporting ensures comprehensive interference detection regardless of terminal state, resolving the contradiction between communication reliability and device complexity.
2Reliability
If the terminal sends IDC indication information in idle or inactive state, then the communication quality is improved, but the loss of time increases due to state transitions required for reporting
Solution Approach 1:
The patent allows terminals to perform IDC detection and send indication information while in idle or inactive states, before transitioning to connected state for data transmission. This preliminary action enables the base station to pre-identify and resolve potential interference issues, avoiding time loss that would occur if state transitions were required solely for IDC reporting.
3Productivity
If the terminal performs IDC detection in idle or inactive state, then the productivity is improved by avoiding communication disruptions, but the use of energy increases due to continuous monitoring
Solution Approach 1:
The patent enables terminals to autonomously perform IDC detection and self-diagnosis in idle or inactive states, identifying interference conditions without requiring base station intervention or additional signaling resources. This self-service approach improves communication efficiency by preventing disruptions while managing energy consumption through intelligent, state-aware monitoring rather than continuous active detection.
