US 2025/0211385 A1 · HYBRID AUTOMATIC REPEAT REQUEST (HARQ) DESIGNS FOR PROBABILISTIC AMPLITUDE SHAPING

Abstract

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for hybrid automatic repeat request (HARQ) designs for probabilistic amplitude shaping (PAS). In some aspects, a device may construct a first buffer including a set of shaped bits and a second buffer including a set of non-shaped bits, the first buffer including a first set of shaped information bits and the second buffer including a second set of non-shaped information bits and a set of non-shaped parity bits. The device may transmit a first instance of a data message using a complete set bits from the first buffer and a first subset of bits from the second buffer. The device may transmit a second instance of the data message using at least one of a subset of bits from the first buffer or a second subset of bits from the second buffer.

Dependent claims

An apparatus for wireless communication, comprising:

an interface configured to:
output a first instance of a data message, wherein the first instance of the data message is associated with a first set of shaped bits and a first set of non-shaped bits;
and
output a second instance of the data message as a retransmission of the data message, wherein the second instance of the data message is associated with at least one of a second set of shaped bits or a second set of non-shaped bits, and wherein the second set of shaped bits and the second set of non-shaped bits are different from the first set of shaped bits and the first set of non-shaped bits, respectively.
