Samsung patents method to compress wireless signal data using AI
Samsung has been granted a patent for a method to compress channel state information, which describes how strong a wireless signal is between a device and a base station. The system breaks the data into small pieces, groups them into categories, and uses a universal encoding block with a masking layer to reduce the amount of data that needs to be sent.
In the filing’s own words
A system and a method are disclosed. The method includes partitioning channel state information (CSI) into one or more discrete elements based on a predetermined dimension; categorizing the partitioned CSI into one or more bins having an equal length; and encoding the categorized partitioned CSI.
What exactly they claim (claim 1)
1. A method performed by an electronic device, comprising: partitioning channel state information (CSI) into one or more discrete elements based on a predetermined dimension; categorizing the partitioned CSI into one or more bins having an equal length; extracting, using a universal encoding block, CSI features of 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 categorized partitioned CSI to obtain encoded data having a length corresponding to the number of first elements.
