Encoding schemes for wire-less communications systems that support constellation shaping

An apparatus for wireless communication at a wireless device, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive at least one control message indicating a resource allocation and an offset that identifies a first resource mapping within the resource allocation for a first set of coded bits and a second resource mapping within the resource allocation for a second set of coded bits, the offset corresponding to a first coding rate associated with the first set of coded bits and a second coding rate associated with the second set of coded bits;
• receive, via the resource allocation, the first set of coded bits in accordance with the first resource mapping and the second set of coded bits in accordance with the second resource mapping based at least in part on the at least one control message;
• perform, based at least in part on the first set of coded bits, a first error correction decoding operation to generate a set of shaping bits;
• perform, based at least in part on the second set of coded bits, a second error correction decoding operation to generate a set of decoded bits;
• and
• generate, based at least in part on the set of decoded bits and the set of shaping bits and using a constellation deshaping operation, a set of information bits.

A method for wireless communication at a wireless device, comprising:

• generating a set of shaping bits based at least in part on performing a constellation shaping operation on a set of information bits;
• performing, based at least in part on the set of shaping bits, a first error correction encoding operation according to a first coding rate to generate a first set of coded bits;
• performing, based at least in part on the set of information bits, a second error correction encoding operation according to a second coding rate to generate a second set of coded bits;
• transmitting at least one control message indicating a resource allocation and an offset that identifies a first resource mapping within the resource allocation for the first set of coded bits and a second resource mapping within the resource allocation for the second set of coded bits, the offset corresponding to the first coding rate and the second coding rate;
• and
• transmitting, via the resource allocation, the first set of coded bits in accordance with the first resource mapping and the second set of coded bits in accordance with the second resource mapping based at least in part on the at least one control message.
