Interference Measurement Resources With Additional PCI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in efficiently configuring channel measurement resources (CMRs) and interference measurement resources (IMRs) across different cells, which affects transmission complexity and performance.
Innovation Solution
The method involves determining whether CMRs and IMRs correspond to a single serving cell or multiple cells, and whether they correspond to a single physical cell identification (PCI) or multiple PCIs. Based on these determinations, the IMRs are configured with additional PCIs or cell IDs, and these resources are transmitted to user equipment (UE) for measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CMRs and IMRs are configured for multiple serving cells and multiple PCIs, then measurement accuracy and interference detection capability are improved, but device complexity and configuration overhead increase
Solution Approach 1:
The patent segments the configuration by introducing separate indication fields for serving cell ID and PCI, allowing independent configuration of these parameters. This enables the system to handle multiple serving cells and PCIs separately rather than as a monolithic configuration, reducing the complexity of managing multi-cell measurements while maintaining measurement accuracy across different cells and physical cell identities
Solution Approach 2:
The patent adds a new dimension to the resource configuration by introducing the serving cell ID as an additional configuration parameter alongside PCI. This dimensional expansion allows the system to distinguish between measurements from different serving cells, enabling more precise interference measurement and channel quality indicator reporting without conflating measurements from different cells
2Adaptability or versatility
If additional PCI or cell ID information is configured in IMRs, then adaptability to multi-cell scenarios is improved, but transmission overhead and signaling complexity increase
Solution Approach 1:
The patent creates a universal configuration framework where the same IMR resources can serve multiple functions across different serving cells and PCIs. By configuring IMRs with associations to multiple serving cell IDs and PCIs, the system enables a single set of measurement resources to be universally applied across multiple cells, reducing the need for separate dedicated resources for each cell and thereby reducing overall signaling overhead
Solution Approach 2:
The patent changes the configuration parameters by introducing serving cell ID as a configurable parameter in IMR settings. This parameter change enables dynamic adaptation to different multi-cell scenarios, allowing the network to flexibly assign IMRs to appropriate serving cells based on measurement needs, thereby improving adaptability without requiring fixed dedicated configurations for each cell
3Manufacturing precision
If separate indication fields for serving cell ID and PCI are introduced, then measurement configuration precision is improved, but message size and processing overhead increase
Solution Approach 1:
The patent segments the configuration information into distinct fields: one field for serving cell ID and another for PCI. This segmentation allows each parameter to be independently configured and processed, improving configuration precision by ensuring that measurements are correctly associated with specific serving cells and physical cell identities. The segmented approach also enables selective updating and processing of individual parameters, reducing unnecessary data transmission
