CONSTELLATION SHAPING CONFIGURATION AND FEEDBACK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18245144 titled 'CONSTELLATION SHAPING CONFIGURATION AND FEEDBACK

Simplified Explanation

- The patent application describes methods, systems, and devices for wireless communications. - A user equipment (UE) receives a configuration from a base station indicating a set of encoding parameters for a constellation shaping encoding process. - The UE calculates the number of bits in a first subset of a source bit stream, which is the input to a distribution matcher. - The UE applies a distribution matcher parameter to the first subset based on the set of encoding parameters. - The UE also calculates the number of bits in a second subset of the source bit stream, which is concatenated with the output of the distribution matcher and used as input to a channel encoder. - The UE signals the source bit stream back to the base station.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration indicating a set of encoding parameters corresponding to a constellation shaping encoding process. The UE may calculate a number of bits of a first subset of a source bit stream, and the first subset of the source bit stream may include or encompass an input to a distribution matcher. The UE may apply, to the first subset, a distribution matcher parameter based on the set of encoding parameters. The UE may calculate a number of bits of a second subset of the source bit stream, and the second subset of the source bit stream may be concatenated with an output bit stream of the distribution matcher as an input to a channel encoder. The UE may signal the source bit stream to the base station.
