Channel State Information Vector Coefficient Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-antenna wireless communication technologies, the existing method of reporting precoding coefficients for channel state information (CSI) consumes excessive resources and reduces accuracy due to the need to report all coefficients each time, leading to a low resource utilization rate and increased energy consumption.
Innovation Solution
A method where the terminal reports channel state information by determining a reference vector coefficient and its variation, allowing separate reporting of the reference vector coefficient and vector coefficient variation, thereby reducing redundant reporting and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all precoding coefficients are reported each time, then channel state information accuracy is maintained, but resource utilization rate decreases and energy consumption increases
Solution Approach 1:
The patent extracts only the necessary coefficient information for reporting. Instead of transmitting all precoding coefficients, the system identifies and reports only the coefficient variations that have changed from the reference state, thereby reducing reporting overhead while maintaining CSI accuracy.
Solution Approach 2:
The patent changes the reporting parameter from absolute coefficient values to coefficient variations relative to a reference. By reporting only the variations (delta values) rather than complete coefficients, the system reduces the amount of data transmitted while preserving the essential channel state information.
2Reliability
If all precoding coefficients are reported each time, then channel state information completeness is ensured, but reporting resource consumption increases
Solution Approach 1:
The patent extracts only the necessary coefficient information for reporting. Instead of transmitting all precoding coefficients, the system identifies and reports only the coefficient variations that have changed from the reference state, thereby reducing reporting overhead while maintaining CSI accuracy.
Solution Approach 2:
The patent segments the precoding coefficients into reference coefficients and variation coefficients. By dividing the complete coefficient set into a reference portion (transmitted once) and a variation portion (transmitted only when changed), the system reduces redundant reporting while ensuring information completeness.
