CSI Reporting Priority for L1-CLI Interference Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no specific implementation method for Layer 1 (L1)-Cross-link interference (CLI) reporting in existing communication technologies, particularly in determining Channel State Information (CSI) reports.
Innovation Solution
The method and apparatus provide a solution for determining the priority value, report content, and calculation delay of L1-CSI reports by incorporating L1-CLI measurement information, using formulas based on network device configuration or terminal capability, and specifying types of measurement information such as RSSI and RSRP to optimize reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If L1-CLI measurement information is incorporated into CSI reports, then measurement precision of cross-link interference is improved, but device complexity increases due to additional reporting parameters and calculation requirements
Solution Approach 1:
The patent combines L1-CLI measurement information with existing CSI reporting mechanisms by introducing a new CSI report type (first CSI report) that carries both traditional CSI parameters and L1-CLI measurement results. This merging approach allows the system to achieve improved measurement precision while reusing existing reporting infrastructure, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent changes the parameter set of CSI reports by adding L1-CLI specific parameters (such as RSSI or RSRP measurements on specific resources) to the existing CSI framework. This parameter extension enables precise L1-CLI measurement reporting while maintaining compatibility with existing CSI processing chains, balancing measurement precision improvement with controlled complexity increase.
2Adaptability or versatility
If multiple CSI report types are introduced with different priorities, then adaptability of the reporting system is improved, but device complexity increases due to priority management and report scheduling
Solution Approach 1:
The patent segments the CSI reporting system into multiple report types with different priorities: first CSI reports for L1-CLI measurements, second CSI reports for L1-RSRP/L1-SINR, and third CSI reports for other purposes. Each report type has assigned priority levels that simplify the scheduling decision process, making the system adaptable to different scenarios while keeping the priority management mechanism relatively simple through clear segmentation.
Solution Approach 2:
The patent introduces dynamic priority management where the priority of CSI reports can be adjusted based on configuration information from the network device and terminal capability. This dynamic adjustment allows the reporting system to adapt to different operational conditions while providing clear rules for priority determination, balancing versatility with manageable complexity.
3Reliability
If L1-CLI configuration information is provided through higher-layer signaling, then reliability of configuration is improved, but loss of time increases due to signaling overhead and processing delay
Solution Approach 1:
The patent uses higher-layer signaling to provide L1-CLI configuration information (such as measurement resource configurations and reporting parameters) in advance before actual L1-CLI measurements are performed. This preliminary configuration ensures reliable and complete measurement parameters are available, improving configuration reliability while allowing the actual measurement and reporting process to proceed efficiently without repeated signaling delays.
