Systems and methods for variable code-rate coding

A wireless communication device, comprising:

• a processing system that includes one or more processors and one or more memories that store code and are coupled with the one or more processors, the processing system configured to cause the wireless communication device to:
• obtain a message vector including multiple bits;
• generate multiple input tokens in accordance with the message vector;
• generate, in accordance with the multiple input tokens and using an artificial neural network, multiple output tokens;
• modify the multiple output tokens to include a total number of symbols that is the same as a total number of symbols of a codeword vector, wherein the modified multiple output tokens are permutation equivariant relative to the multiple input tokens;
• generate the codeword vector in accordance with the modified multiple output tokens;
• and
• transmit the codeword vector.

A method of wireless communication by a wireless communication device, comprising:

• obtaining a message vector including multiple bits;
• generating multiple input tokens in accordance with the message vector, wherein each of one or more input token of the multiple input tokens includes at least one respective bit of the multiple bits;
• generating, in accordance with the multiple input tokens and using an artificial neural network, multiple output tokens;
• modifying the multiple output tokens to include a total number of symbols that is the same number as a total number of symbols of a codeword vector, wherein the modified multiple output tokens are permutation equivariant relative to the multiple input tokens;
• generating the codeword vector in accordance with the modified multiple output tokens;
• and
• transmitting the codeword vector.
