Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple CSI report configurations are used to support beam information measurement at multiple moments, then measurement capability is improved, but configuration overhead increases
Solution Approach 1:
The patent merges multiple CSI report configurations into a single unified CSI report configuration. The network device configures one CSI report configuration that includes multiple CSI resource configurations, each corresponding to different time moments. The terminal uses this single configuration to measure and report beam information at multiple time points, eliminating the need for separate configurations and reducing configuration overhead while maintaining comprehensive measurement capability.
Solution Approach 2:
The unified CSI report configuration serves multiple functions simultaneously. It configures CSI resource configurations for channel measurement, CSI interference measurement, and beam information measurement at different time moments. This multi-functional configuration structure allows the terminal to perform diverse measurements using a single configuration, reducing the number of configuration messages needed.
2Measurement precision
If multiple CSI report configurations are used to support beam information measurement at multiple moments, then measurement capability is improved, but uplink channel overhead increases
Solution Approach 1:
The patent combines multiple CSI reports into a single unified CSI report. Instead of the terminal sending separate CSI reports for each time moment, the unified configuration enables the terminal to aggregate beam information measurements from multiple time points into one report. This reduces the number of uplink transmissions and decreases uplink channel overhead while preserving comprehensive measurement data.
3Loss of information
If a single CSI report configuration is used to measure multiple beam information at multiple moments, then configuration overhead is reduced, but measurement complexity increases
Solution Approach 1:
The patent segments the unified CSI report configuration into multiple CSI resource configurations, where each resource configuration corresponds to a specific time moment or beam. This segmentation allows the terminal to process measurements in an organized manner, associating each measurement with its corresponding time point and beam, thereby managing complexity through structured organization rather than overwhelming monolithic processing.
Solution Approach 2:
The network device performs preliminary configuration by pre-defining the unified CSI report configuration with all necessary CSI resource configurations for multiple time moments. This preliminary setup provides the terminal with a clear measurement framework beforehand, reducing the complexity of real-time measurement and reporting decisions. The terminal simply follows the pre-established configuration structure during actual measurements.
