SUBBAND LEVEL CONSTELLATION SHAPING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18044973 titled 'SUBBAND LEVEL CONSTELLATION SHAPING
Simplified Explanation
Methods, systems, and devices for wireless communication at a user equipment (UE) are described in this patent application. The UE receives a configuration that specifies how to map multiple subband indices to multiple encoding parameter sets. The UE then applies a specific encoding parameter set to a subset of a bit stream using a distribution matcher. This process is repeated for another subset of the bit stream using a different encoding parameter set. The first encoding parameter set is associated with a first subband index, while the second encoding parameter set is associated with a second subband index. Finally, the UE transmits the modulated bit streams on their respective subbands.
- User equipment (UE) receives a configuration indicating the mapping between subband indices and encoding parameter sets.

Original Abstract Submitted
Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A user equipment (UE) may receive a configuration indicating a mapping between a set of multiple subband indices and a set of multiple encoding parameter sets. The UE may apply, at a first distribution matcher, a first encoding parameter set to a first subset of a bit stream. The UE may also apply, at a second distribution matcher, a second encoding parameter set to a second subset of the bit stream. The a first encoding parameter set may be associated with a first subband index and the second encoding parameter set may be associated with a second subband index. The UE may then transmit a first modulated bit stream on a first subband, and a second modulated bit stream on a second subband.
