Abstract
Certain aspects of the present disclosure provide techniques for a probabilistic constellation shaping (PCS) scheme for multiple layer transmissions. An example method includes obtaining a configuration for performing a PCS modulation scheme, identifying a set of bits corresponding to a transport block for communication via the multi-layer transmission, performing distribution matching on the set of bits using a set of parameters indicated in the configuration to obtain a set of distributed symbols, converting the set of distributed symbols into a set of distributed bits, encoding the set of distributed bits to obtain an encoded set of distributed bits, performing a modulation procedure on the encoded set of distributed bits in accordance with the PCS modulation scheme to obtain a set of modulation symbols corresponding to a codeword associated with the transport block, and transmitting, to a receiving device, the codeword, including the set of modulation symbols, via the multi-layer transmission.
