Classification: CPC H | IPC H

Claim 0:
1. An apparatus for wireless communication at a user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory and configured to:
encode a plurality of bits associated with quadrature amplitude modulation (QAM), the plurality of bits corresponding to a circular buffer associated with at least one redundancy version (RV), the plurality of bits including a plurality of systematic bits, wherein the plurality of systematic bits are grouped into clusters of systematic bits corresponding to constellation shaping of the QAM;
transfer the plurality of bits from the circular buffer associated with the at least one RV to an amplitude bit buffer and a sign bit buffer for the QAM, wherein one or more of the clusters of systematic bits are transferred to the amplitude bit buffer to preserve the constellation shaping; and
map the plurality of bits from the amplitude bit buffer and the sign bit buffer to a plurality of modulation symbols.
