CSI Reporting Mode Feedback for UE-Network Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular mobile communication systems face challenges in accurately determining and efficiently managing Channel State Information (CSI) reporting modes due to unilateral configuration by the network, leading to inefficiencies and reduced spectrum efficiency.
Innovation Solution
User Equipment (UE) sends an update request to indicate the applicability of the currently configured CSI reporting mode, allowing the network to adjust and align the CSI reporting mode with the UE's capabilities and conditions, using AI-based CSI compression to enhance accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network unilaterally configures CSI reporting mode, then the network can control the reporting process, but the accuracy of CSI reporting decreases due to mismatches with UE capabilities
Solution Approach 1:
The patent implements a feedback mechanism where the UE sends an update request to the network side device to indicate whether the currently configured CSI reporting mode is applicable. This feedback loop allows the network to adjust the configuration based on actual UE capabilities and conditions, resolving the contradiction between network control and reporting accuracy.
Solution Approach 2:
The patent introduces dynamic adjustment of CSI reporting modes based on real-time UE feedback. Instead of static unilateral configuration, the system evolves into a dynamic negotiation process where the reporting mode can be adjusted according to changing UE capabilities and network conditions, improving accuracy while maintaining manageable complexity.
2Measurement precision
If AI-based CSI compression is used, then the accuracy and efficiency of CSI reporting improve, but the signaling overhead increases
Solution Approach 1:
The patent utilizes AI-based compression algorithms that transform and encode CSI parameters efficiently. By changing the representation parameters of CSI data through AI compression, the system achieves higher measurement precision while controlling the quantity of transmitted signaling data, effectively managing the trade-off between accuracy and overhead.
