Joint CSI and CLI Reporting Configuration in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in reporting channel state information (CSI) and cross-link interference (CLI) due to separate configurations and measurements, leading to increased overhead and resource utilization.
Innovation Solution
Implementing a joint configuration and reporting method for CSI and CLI, where a network entity transmits a single configuration indicating resources for both CSI and CLI measurements, allowing user equipment (UE) to generate and report both types of information jointly, using shared or distinct resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate configurations and measurements are used for CSI and CLI reporting, then measurement precision and reliability are maintained, but overhead and resource utilization increase
Solution Approach 1:
The patent combines separate CSI and CLI reporting configurations into a unified joint configuration. The network entity transmits a single joint configuration message that includes both CSI resource settings (for channel state information) and CLI resource settings (for cross-link interference measurement), enabling the UE to perform both measurements and report both types of information through a unified reporting mechanism, thereby reducing signaling overhead and resource utilization while maintaining measurement reliability
Solution Approach 2:
The joint configuration structure serves multiple functions simultaneously: it configures both CSI and CLI measurements, defines resource allocation for both measurement types, and establishes reporting parameters for both information types. This multi-functional configuration approach eliminates the need for separate configuration messages and reduces the overall quantity of configuration data transmitted
2Loss of information
If separate reporting mechanisms are used for CSI and CLI, then information completeness is ensured, but device complexity and processing overhead increase
Solution Approach 1:
The patent merges separate CSI reporting and CLI reporting mechanisms into a single joint reporting structure. The UE processes one unified configuration and generates a combined report that includes both CSI metrics (such as CQI, PMI, RI) and CLI metrics (such as RSRP, RSSI, SINR), reducing the complexity of maintaining separate reporting logic while ensuring all necessary information is captured
3Quantity of substance
If joint configuration is implemented for CSI and CLI, then overhead and resource utilization are reduced, but configuration complexity increases
Solution Approach 1:
The joint configuration is segmented into distinct functional components: CSI resource settings (including CSI-RS resources, interference measurement resources) and CLI resource settings (including SRS resources for CLI measurement). Each segment maintains its own parameter structure and measurement requirements, allowing the UE to process them independently while benefiting from the unified configuration approach that reduces overall overhead

AI summary
Methods, systems, and devices for wireless communication are described. Generally, the techniques described herein may enable joint reporting of channel state information (CSI) and cross-link interference (CLI). For example, a network entity may transmit, to a user equipment (UE), a joint configuration indicative of a first set of resources associated with generation of one or more CSI metrics and a second set of resources associated with generation of one or more CLI metrics. As such, the UE may generate the one or more CSI metrics and one or more CLI metrics in accordance with the joint configuration and transmit a joint report indicative of the one or more CSI metrics and the one or more CLI metrics.
