Apple patents AI method for improving wireless signal feedback
Apple describes a system where a phone sends data to a network to help train an AI model. This model learns to interpret complex radio signals, known as channel state information, more accurately. The network uses this training to better understand how the phone receives data.
In the filing’s own words
Methods and apparatus are provided for Type 3 training for artificial intelligence (AI) enabled channel state information (CSI) feedback. A user equipment (UE) obtains a decoder model-ID from a network for the CSI feedback, determines an encoder model according to the decoder model-ID or including the decoder model-ID as an input to the AI encoder, and feeds a latent space representation for CSI feedback.
What exactly they claim (claim 1)
1. A method for a network node, the method comprising: receiving a training dataset from a user equipment (UE), the training dataset comprising a set of inputs for an encoder for channel state information (CSI) feedback, a corresponding set of latent space representations, and a reference to a source of the training dataset; parsing the training dataset to determine the set of inputs, the set of latent space representations, and the reference to the source; inputting the set of latent space representations and the reference to the source into an artificial intelligence (AI) decoder for CSI feedback, and training a decoder model for the AI decoder to output a target CSI that matches the set of inputs, wherein the decoder model is associated with the reference to the source of the training dataset.
