Electronic device and method to perform universal learning-based channel state information compression

An electronic device, comprising:

• a memory device, and
• a processor configured to execute instructions stored on the memory device, wherein the instructions cause the processor to:
• partition channel state information (CSI) into one or more discrete elements based on a predetermined dimension;
• categorize the partitioned CSI into one or more bins having an equal length;
• extract, using a universal encoding block, CSI features of a maximum latent vector size;
• generate a masking layer having first elements set to one and remaining elements set to zero, wherein a number of the first elements is less than or equal to the maximum latent vector size;
• apply the masking layer to an output of the universal encoding block;
• and
• encode the categorized partitioned CSI to obtain encoded data having a length corresponding to the number of first elements.

A method performed by an electronic device, comprising:

• obtaining a universal encoding block;
• determining at least one characteristic of channel state information (CSI) included in the universal encoding block corresponding to a maximum latent vector size;
• generating a masking layer having first elements set to one and remaining elements set to zero, wherein a number of the first elements is less than or equal to the maximum latent vector size;
• applying the masking layer to an output of the universal encoding block;
• and
• encoding the CSI based on the masking layer to obtain encoded data having a length corresponding to the number of first elements.
