Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing measurement methods are used, then measurement simplicity is maintained, but interference caused by wireless auxiliary devices cannot be measured, leading to unstable communication quality
Solution Approach 1:
The patent segments the interference measurement process into distinct components: separating the measurement of interference from neighboring cells versus interference from wireless auxiliary devices. The base station configures different measurement objects (neighboring cell reference signals and auxiliary device reference signals) that can be measured independently, allowing precise identification of each interference source while maintaining manageable system complexity.
Solution Approach 2:
The patent introduces an intermediary measurement mechanism where the base station configures measurement parameters and receives measurement reports from terminals. This intermediary process enables the system to indirectly measure and assess interference from wireless auxiliary devices through configured reference signals, without requiring direct interaction between the auxiliary device and measurement system.
2Reliability
If wireless auxiliary devices are deployed to improve communication quality, then signal forwarding capability is enhanced, but interference to neighboring cells increases and cannot be effectively measured
Solution Approach 1:
The patent implements a feedback mechanism where terminals measure reference signals from both neighboring cells and wireless auxiliary devices, then report measurement results to the base station. The base station uses this feedback to assess interference levels and adjust transmission parameters, enabling dynamic optimization of communication quality while controlling interference to neighboring cells.
Solution Approach 2:
The patent enables parameter changes in the measurement process by configuring different measurement objects, measurement frequencies, and reporting thresholds. The base station can adjust measurement parameters based on traffic conditions, channel characteristics, and interference levels, allowing flexible optimization of communication reliability while managing interference impacts.
3Measurement precision
If interference measurement is expanded to include wireless auxiliary devices, then interference assessment accuracy is improved, but signaling load and measurement complexity increase
Solution Approach 1:
The patent applies partial action by configuring measurements only for specific reference signals that are most relevant to interference assessment. Instead of measuring all possible signals, the base station selectively configures measurement objects for neighboring cell reference signals and auxiliary device reference signals, reducing unnecessary signaling while maintaining accurate interference assessment.
