CSI-IM Resource Segmentation for Full-Duplex Interference Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a mechanism to configure user equipment (UE) for separate interference measurements between full-duplex (FD) and half-duplex (HD) sets of symbols, leading to inadequate interference assessment due to differing interference patterns between these symbol types.
Innovation Solution
Configuring channel state information (CSI) interference measurement resources (CSI-IM resources) to enable UE to perform separate interference measurements for FD and HD sets of symbols, allowing for flexible reporting of interference metrics that are not constrained by channel measurement configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate CSI-IM resources are configured for FD and HD symbol sets, then interference measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the interference measurement resources into separate CSI-IM resource sets for FD symbol sets and HD symbol sets. This segmentation allows the UE to perform interference measurements specifically tailored to each symbol type, improving measurement precision by accounting for different interference patterns in FD versus HD operations.
Solution Approach 2:
The patent applies local quality by configuring different interference measurement resources for different symbol types (FD vs HD). Each resource set is optimized for its specific symbol type, with FD resources handling cross-link interference and HD resources handling traditional interference, thereby improving overall measurement accuracy through localized optimization.
2Reliability
If separate interference measurements are performed for FD and HD symbols, then communication reliability is improved, but power consumption increases
Solution Approach 1:
By segmenting interference measurements into separate FD and HD resource sets, the UE can selectively perform measurements based on the current symbol type. This segmentation improves reliability by ensuring appropriate interference assessment for each symbol type while potentially reducing power consumption by avoiding unnecessary measurements.
Solution Approach 2:
The patent changes the measurement parameters dynamically based on symbol type. The network configures different CSI-IM resource sets with parameters optimized for FD or HD operations, allowing the UE to adjust its measurement behavior accordingly. This improves reliability through accurate interference assessment while managing power consumption through parameter optimization.
3Adaptability or versatility
If flexible CSI report configurations are implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal CSI report configuration framework that can handle both FD and HD interference measurements. The same reporting mechanism is used for both resource sets, providing versatility in handling different symbol types while maintaining a unified configuration approach that reduces overall system complexity.
Solution Approach 2:
The patent introduces dynamic adaptability by allowing the network to flexibly configure and switch between different CSI-IM resource sets based on traffic requirements and symbol types. This dynamic configuration capability improves system adaptability while the standardized configuration procedures help manage complexity.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating one or more channel state information (CSI) report configurations that configure one or more CSI interference measurement (CSI-IM) resources, including a CSI-IM resource associated with a full-duplex (FD) set of symbols and a CSI-IM resource associated with a half-duplex (HD) set of symbols. The UE may perform interference measurements associated with at least one of the FD set of symbols, using the CSI-IM resource associated with the FD set of symbols, or the HD set of symbols, using the CSI-IM resource associated with the HD set of symbols. The UE may transmit one or more CSI reports reporting the interference measurements associated with the at least one of the FD set of symbols or the HD set of symbols. Numerous other aspects are described.
