Multi-Task CSI Autoencoder for Multi-Vendor Model Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-vendor setups, switching between different encoder and decoder modules for Channel State Information (CSI) in wireless communication requires significant time and memory resources, leading to inefficiencies and increased costs.
Innovation Solution
Implementing multi-task learning for autoencoders that combine reconstruction and classification tasks, allowing the encoder and decoder modules to adapt to specific vendor identities without the need for multiple pairs, using shared parameters and a combined loss function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pairs of encoder and decoder modules are provided for different vendors, then adaptability to different vendors is improved, but device complexity and memory requirements increase
Solution Approach 1:
The patent implements a universal encoder module that can process CSI data from multiple different vendors using a single module. The encoder is designed with vendor-agnostic architecture that adapts to different vendors through configuration parameters rather than requiring separate hardware modules, thereby achieving multi-vendor support without increasing device complexity
Solution Approach 2:
The patent merges multiple vendor-specific encoder and decoder modules into single universal modules. By combining the functionality of what would traditionally require separate vendor-specific modules into unified structures, the system reduces the total number of modules needed while maintaining support for multiple vendors through software configuration
2Adaptability or versatility
If multiple pairs of encoder and decoder modules are switched between vendors, then adaptability is improved, but switching time increases
Solution Approach 1:
The patent implements dynamic vendor adaptation where the encoder and decoder modules can change their operational characteristics on-the-fly based on the active vendor. Rather than physically switching between static modules, the system dynamically adjusts parameters and configurations of universal modules to match the current vendor requirements, enabling rapid vendor transitions without copying and switching overhead
Solution Approach 2:
The patent pre-configures universal encoder and decoder modules to support multiple vendors within a single module structure. By preparing the module to handle multiple vendor formats in advance through software configuration rather than physical switching, the system eliminates the time-consuming module copying and switching process that would otherwise be required when vendor changes occur
3Adaptability or versatility
If more memory is allocated to store all encoder/decoder pairs, then adaptability is improved, but device cost increases
Solution Approach 1:
The patent employs universal encoder and decoder modules that can serve multiple vendors through software configuration rather than requiring separate dedicated modules for each vendor. This universal approach dramatically reduces the memory required to store encoder/decoder pairs, as a single module can be reconfigured to handle different vendors' CSI data formats and requirements
Solution Approach 2:
The patent utilizes parameter-based configuration to adapt universal encoder and decoder modules to different vendors. By changing software parameters and configuration settings rather than loading different module implementations, the system achieves vendor-specific functionality without the memory overhead of storing multiple complete module sets, reducing memory requirements from O(n) to O(1) where n is the number of vendors

AI summary
Embodiments described herein relate to methods and apparatuses for training a first machine learning, ML, model and a second ML model. A computer-implemented method of training a first ML model comprises: receiving a first latent space representation of a first channel state information, CSI, training data set, H1, from a first wireless device; decoding, using first parameters of the first ML model, the first latent space representation to determine a first reconstructed CSI data set; classifying, using second parameters of the first ML model, the first latent space representation to estimate an estimated classification; determining a first loss based on the estimated classification and a true classification; and updating the first parameters and the second parameters based on the determined first loss.
