Terminal Device CSI Report Priority and Power Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently configuring and reporting channel state information (CSI) for terminal devices with multiple antenna elements, particularly in supporting panel-related CSI reports and managing priority and transmission power effectively.
Innovation Solution
The proposed solution involves methods for determining priority values for CSI reports based on their association with sets of capability parameters, processing multiple CSI reports by selecting, dropping, or combining them, and allocating transmission power based on the association relationship and time-domain behavior of CSI reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple CSI reports are generated for different antenna panels, then the completeness of channel state information is improved, but the complexity of processing and managing multiple reports increases
Solution Approach 1:
The patent segments the channel state information reporting by creating separate CSI reports for different antenna panels. Each panel's capability parameters are independently evaluated and reported, allowing the system to manage complex multi-panel configurations through structured division of reporting tasks.
Solution Approach 2:
The patent introduces priority values as a new parameter to differentiate and manage multiple CSI reports. By assigning priority levels based on panel importance or configuration, the system can systematically handle multiple reports without overwhelming processing complexity.
2Productivity
If priority values are assigned to CSI reports based on capability parameters, then the efficiency of report transmission is improved, but the complexity of determining and managing priority relationships increases
Solution Approach 1:
The patent assigns priority values to CSI reports based on their association with capability parameters. This parameter-based priority system allows the terminal to efficiently determine transmission order and resource allocation, improving reporting efficiency while maintaining manageable complexity through systematic rules.
3Reliability
If transmission power is allocated based on association relationship and time-domain behavior, then the optimization of reporting performance is improved, but the complexity of power management increases
Solution Approach 1:
The patent applies differentiated power allocation strategies based on local characteristics of each CSI report, including its association relationship with capability parameters and time-domain behavior. This allows optimized power distribution tailored to specific reporting requirements while maintaining systematic power management.

AI summary
Example embodiments of the present disclosure relate to an effective mechanism for processing the CSI reports. In this solution, the terminal device determines a first priority value for a first channel state information (CSI) report at least in part based on an association relationship between the first CSI report and a set of capability parameters and further transmits the CSI report to a network device based on the determined priority value. In this way, a feasibly solution for calculating priority value is achieved, which may be satisfy requirements of different scenarios.
