Neural Network Layer Configuration Indicator for CSI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in processing and maintaining channel state information (CSI) due to the need for repeated training of neural networks for each signal or channel, leading to increased processing power and latency.
Innovation Solution
The method involves training a set of neural network layers using channel estimates and generating weights for these layers, which are then used to process other signals by reusing the trained layers based on an association indicator, thereby avoiding the need for cold-start training and reducing processing power and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If neural networks are trained separately for each signal or channel, then processing accuracy is improved, but processing power consumption and latency increase
Solution Approach 1:
The patent applies universality by training a single neural network model that can process multiple different signals and channels (CSI, beam management, positioning, etc.) rather than training separate models for each. The neural network is configured with multiple output heads or processing paths that can handle different signal types, making one model serve multiple functions and reducing overall training requirements.
Solution Approach 2:
The patent merges the processing of multiple signals and channels into a unified neural network architecture. Instead of having separate neural networks for CSI processing, beam management, and positioning, the invention combines these functionalities into one integrated model that shares common layers and parameters, thereby reducing total training power and enabling cross-signal knowledge transfer.

Solution Approach 1:
The patent applies universality by training a single neural network model that can process multiple different signals and channels (CSI, beam management, positioning, etc.) rather than training separate models for each. The neural network is configured with multiple output heads or processing paths that can handle different signal types, making one model serve multiple functions and reducing overall training requirements.
Solution Approach 2:
The patent applies preliminary action by performing a single comprehensive training of the unified neural network model in advance, rather than repeatedly training separate models for each signal type. This preliminary training establishes a foundation model that can be quickly adapted or directly applied to various signals, eliminating the need for repeated training processes and reducing latency.
3Reliability
If separate neural networks are trained for different signals, then signal-specific performance is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by training a single neural network model that can process multiple different signals and channels (CSI, beam management, positioning, etc.) rather than training separate models for each. The neural network is configured with multiple output heads or processing paths that can handle different signal types, making one model serve multiple functions and reducing overall training requirements.
Solution Approach 2:
The patent applies segmentation by dividing the unified neural network into distinct processing paths or output heads for different signal types (CSI processing, beam management, positioning). This segmentation allows the model to maintain signal-specific performance while being managed as a single integrated entity, reducing the complexity of managing multiple separate models.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may train a first set of layers of a neural network based on channel estimates using a set of resources. The UE may generate a set of weights for the first set of layers of the neural network based on the training. The UE may receive, from a first network entity, an indication of an association between a first set of signaling and a second set of signaling based on the first set of layers of the neural network. The UE may receive the second set of signaling from a second network entity and process the second set of signaling using the set of weights for the first set of layers based on the association between the first set of signaling and the second set of signaling.
