Terminal CSI Report Segmentation for Mid-Speed Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems, such as NR, face challenges in accurately reporting channel state information (CSI) for user terminals moving at middle speeds, leading to potential deterioration in communication throughput and quality due to insufficient measurement and reporting methods for movement-related influences.
Innovation Solution
A terminal equipped with a control section that determines multiple parts of CSI reports, each corresponding to different time occasions, and a transmitting section that transmits these parts to enhance measurement and reporting, particularly for middle-speed movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement and reporting methods are not optimized for moving terminals, then communication throughput and quality deteriorate, but implementing optimized methods increases system complexity
Solution Approach 1:
The CSI report is divided into multiple parts, each corresponding to different time occasions. The control section determines multiple parts of CSI reports including multiple pieces of CSI respectively corresponding to multiple time occasions, and the transmitting section transmits these parts separately. This segmentation allows the system to handle movement-related channel changes more effectively without overwhelming the reporting mechanism.
Solution Approach 2:
The patent implements dynamic CSI reporting by capturing channel state information at multiple different time occasions. The control section adapts the reporting to reflect temporal variations in channel conditions, allowing the system to respond dynamically to terminal movement and maintain reliable communication quality.
2Measurement precision
If CSI reporting captures temporal variations for moving terminals, then measurement precision improves, but information processing complexity increases
Solution Approach 1:
By segmenting the CSI report into multiple parts corresponding to different time occasions, the patent captures temporal variations in channel state without requiring a single overwhelming report. Each part contains CSI for a specific time occasion, making the information more manageable and precise for moving terminals.
Solution Approach 2:
The control section determines multiple parts of CSI reports in advance, preparing the information structure before transmission. This preliminary organization of CSI data for multiple time occasions reduces processing complexity during actual transmission and reception.
