Abstract: Methods, systems, and devices for wireless communication are described to support replacing values of one or more information bit vectors with one or more corresponding sets of parity bits. A first wireless device may replace an information bit vector with a parity bit vector, using a set of information bits of the information bit vector and based on a parity check matrix, which may result in generating the set of information bits at an information bit vector corresponding to a parity bit column of the parity check matrix, during encoding. The first wireless device may perform a transmission to a second wireless device, which may receive the transmission, decode the set of information bits to the information bit vector corresponding to the parity bit column. The second wireless device may replace other bit estimates of a vector corresponding to an information bit column with the set of information bits.

Abstract: Methods, systems, and devices for scrambling for probabilistic constellation schemes (PCSs) in wireless communications are described. In some examples, a first wireless device may scramble a set of amplitude information bits associated with a transport block for transmission to a second wireless device. In such examples, the first wireless device may perform a distribution matching procedure on the scrambled set of amplitude information bits. The first wireless device may encode the set of distributed amplitude bits and, in some cases, may perform a modulation procedure on the encoded set of distributed amplitude bits in accordance with a PCS scheme to obtain a codeword associated with the transport block. In some examples, the first wireless device may transmit the codeword to the second wireless device.
