Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular network technologies face inefficiencies in channel state information (CSI) reporting, particularly with the extensive overhead and complexity of CSI Type II configurations, which can lead to suboptimal resource allocation and performance in varying network conditions.
Innovation Solution
A hybrid CSI reporting system dynamically selects between CSI Type I and Type II configurations based on factors such as throughput capacity, Doppler metric, reference signal measurement, and UE resource limitations, using AI-ML models to optimize CSI reporting for improved efficiency and reduced latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CSI Type II configuration is used for CSI reporting, then measurement precision and throughput capacity are improved, but device complexity and overhead increase significantly
Solution Approach 1:
The system dynamically selects between CSI Type I and Type II configurations based on current network conditions, UE capabilities, and channel characteristics. This dynamic adaptation allows the system to use the more precise Type II configuration when conditions permit, while falling back to the simpler Type I configuration when complexity or overhead becomes prohibitive, thus resolving the contradiction between precision and complexity
Solution Approach 2:
The invention changes the parameter of CSI configuration type based on varying conditions such as channel state, UE mobility, and network load. By adjusting this parameter dynamically, the system optimizes the balance between measurement precision and device complexity, using Type II only when its additional precision is actually needed
2Productivity
If CSI Type II configuration is used for CSI reporting, then throughput capacity is improved, but overhead increases significantly
Solution Approach 1:
The system dynamically adjusts the CSI reporting configuration based on actual throughput requirements and channel conditions. When high throughput is needed and channel conditions are stable, Type II is selected. When conditions change or throughput requirements are met with Type I, the system switches to reduce overhead, thus dynamically balancing throughput capacity and reporting overhead
Solution Approach 2:
Instead of always using the more comprehensive Type II configuration, the system applies partial action by selectively using Type I configuration when full Type II precision is not needed. This partial approach reduces overhead while maintaining sufficient throughput capacity for many practical scenarios
3Adaptability or versatility
If dynamic selection between CSI Type I and Type II is implemented, then adaptability to varying network conditions is improved, but device complexity increases
Solution Approach 1:
The invention segments the CSI configuration space into distinct Type I and Type II options with clearly defined selection criteria. By segmenting the decision space and providing structured guidance for selection, the system improves adaptability while managing device complexity through organized, rule-based or AI-assisted decision-making rather than unstructured complexity

AI summary
The present application relates to channel state information (CSI) signaling and computing. In an example, a network configures a user equipment (UE) with multiple CSI configurations including a CSI Type I configuration and a CSI Type II configuration. Based on a set of factors, the network and/or the UE can dynamically determine the CSI configuration from among the multiple CSI configurations that is most suitable to use. When generating a CSI report, this CSI configuration is used. Further, in the case of the CSI Type II configuration being used for the CSI report, the UE can use information derived from using the CSI Type I configuration to reduce the complexity of the CSI Type II computations.
