Port-wise Interference Measurement Resource for Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently measuring interference, particularly in multi-user scenarios where configuring interference measurement resources is complex due to the need to consider multiple interference hypotheses, leading to resource overhead and accuracy issues.
Innovation Solution
The implementation of a port-wise interference measurement resource (PIMR) method, where each port in the PIMR has a distinct interference hypothesis, allowing the user equipment (UE) to independently measure and report interference, reducing resource usage and improving accuracy by emulating interference for each port and calculating Channel Quality Indicators (CQI) based on these measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional interference measurement resources are configured to cover multiple interference hypotheses, then measurement coverage is improved, but resource overhead increases and measurement precision deteriorates
Solution Approach 1:
The patent segments interference measurement by creating separate port-wise interference measurement resources (PIMR) for each antenna port. Each PIMR is configured independently with its own interference measurement hypothesis, allowing precise measurement per port rather than using a single shared resource that must cover all hypotheses, thereby reducing overall resource overhead while maintaining comprehensive measurement coverage.
Solution Approach 2:
The patent applies local quality by configuring interference measurement resources with port-specific characteristics. Each antenna port receives tailored interference measurement configuration including port-specific reference signal resources and interference hypotheses, enabling localized optimization of measurement accuracy for each port's specific interference environment rather than using a uniform approach.
2Adaptability or versatility
If traditional interference measurement resources are configured to cover multiple interference hypotheses, then measurement coverage is improved, but measurement precision deteriorates
Solution Approach 1:
By segmenting interference measurement into port-specific PIMR configurations, each port can have its own dedicated interference hypothesis and measurement resource. This segmentation eliminates the compromise required when sharing resources across multiple hypotheses, allowing each port to achieve optimal measurement precision for its specific interference scenario while collectively covering all necessary interference types.
Solution Approach 2:
The patent implements local quality through port-specific interference measurement configuration where each antenna port is assigned customized interference measurement resources and hypotheses matched to its local interference environment. This localized approach ensures that each measurement is optimized for its specific context, dramatically improving measurement precision compared to a generic shared resource approach.
3Measurement precision
If port-wise interference measurement resource is implemented with independent interference hypothesis for each port, then interference measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a standardized PIMR configuration framework that can be systematically applied to each antenna port. The configuration structure includes reusable elements such as standard reference signal resource definitions, template-based interference hypothesis settings, and uniform reporting formats, which reduce the actual implementation complexity despite the increased number of ports being measured.
4Measurement precision
If port-wise interference measurement resource is implemented with independent interference hypothesis for each port, then channel quality assessment is improved, but resource configuration complexity increases
Solution Approach 1:
The patent implements universality through a standardized PIMR configuration framework that provides multi-functional capability. The same configuration structure serves multiple ports simultaneously, with reusable reference signal resource definitions and template-based interference hypotheses that can be instantiated for each port, thereby reducing configuration complexity while maintaining precise channel quality assessment for all ports.
