CSI Reporting Updates for Dynamic Antenna Configuration Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current communication systems, during periods of low network load or when only a small number of users are active, the Channel State Information (CSI) configuration is not updated, leading to unnecessary measurements and inaccurate CSI reporting, which hinders efficient scheduling.
Innovation Solution
A method and apparatus for channel state information reporting and processing, where a terminal receives indication information from a network side device to adjust CSI reporting configuration, allowing for accurate CSI reporting based on the indicated changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the network disables certain antenna units to conserve energy during low network load, then energy consumption is reduced, but the CSI configuration is not updated and leads to inaccurate CSI reporting
Solution Approach 1:
The patent implements a feedback mechanism where the terminal receives indication information from the network side device about antenna unit status changes. The terminal then adjusts its CSI measurement and reporting accordingly, ensuring that CSI accuracy is maintained even when antenna units are disabled for energy saving. This feedback loop resolves the contradiction by allowing the system to adapt to changing network conditions.
Solution Approach 2:
The patent introduces dynamic adjustment of CSI configuration based on real-time network conditions. When antenna units are disabled or enabled, the system dynamically updates the CSI measurement and reporting parameters to match the current active antenna configuration. This dynamic approach ensures that energy saving measures do not compromise CSI accuracy.
2Duration of action of stationary object
If the terminal continues to perform measurements based on outdated configuration, then measurement continuity is maintained, but the reported CSI becomes inaccurate and hinders efficient scheduling
Solution Approach 1:
The patent applies preliminary action by having the terminal receive and process indication information about configuration changes before performing the next measurement cycle. The terminal prepares to adjust its measurement parameters in advance based on the indication information, ensuring that when measurements are performed, they are both continuous and accurate, thereby maintaining scheduling efficiency.
