CLI Reporting by Serving Cell for Wireless Interference Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face challenges with cross-link interference (CLI) and self-interference (SI) that degrade performance, particularly as demand for mobile broadband access increases and more devices access long-range and short-range systems, leading to network congestion.
Innovation Solution
Enhanced reporting mechanisms for CLI and SI are implemented, including the generation and transmission of CLI and SI reports with type indications for actual or estimated interference information, enabling remediation actions to reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If enhanced reporting mechanisms with multiple CLI reports and type indications are implemented, then interference mitigation capability is improved, but device complexity and signaling overhead increase
Solution Approach 1:
The CLI report information is segmented into multiple independent CLI reports, each corresponding to a specific serving cell. Each report contains only the relevant CLI information for that cell, allowing the system to handle interference on a per-cell basis rather than processing all interference data centrally, thus reducing overall complexity while maintaining comprehensive interference mitigation capability.
Solution Approach 2:
Each CLI report is tailored with specific type indications (actual CLI information, estimated CLI information, or both) based on the particular needs and characteristics of each serving cell. This allows different reporting granularities and information types to be applied locally to each cell rather than using a uniform reporting structure across all cells, optimizing the balance between detail and complexity for each specific interference scenario.
2Measurement precision
If detailed CLI information reporting for multiple cells is implemented, then network performance monitoring is improved, but signaling overhead and loss of information increase
Solution Approach 1:
The system implements partial reporting by including only the necessary CLI information types for each serving cell based on specific conditions. The type indication field allows selective reporting of actual CLI information, estimated CLI information, or both, depending on what is needed for effective interference mitigation in each specific scenario, avoiding the transmission of redundant information and reducing signaling overhead while maintaining measurement precision where required.

AI summary
This disclosure provides systems, methods, and devices for wireless communication that support enhanced cross-link interference (CLI) and self-interference (SI) reporting. In a first aspect, an apparatus for wireless communication includes at least one processor; and a memory coupled to the at least one processor. The at least one processor is configured to: generate cross-link interference (CLI) information corresponding to cross-link interference; and transmit CLI report information including one or more CLI reports. Each CLI report corresponds to a respective serving cell of one or more serving cells, and each CLI report includes respective CLI information. Each CLI report of the one or more CLI reports includes a respective report type indication, and each respective report type indication is indicative of whether the CLI information includes actual CLI information or estimated CLI information. Other aspects and features are also claimed and described.
