Abstract: ABSTRACT OF THE DISCLOSURE BOUNDARY IDENTIFICATION FOR PROBABILISTIC AMPLITUDE SHAPING This disclosure provides methods, devices and systems for amplitude shaping encoding, and specifically, for indicating boundaries in bitstreams encoded using amplitude shaping encoding. In some aspects, a transmitting device may insert, into an bitstream to indicate a boundary, a sequence of amplitude bits not associated with any patterns of bit values in a lookup table used for the encoding. In some other aspects, a transmitting device may monitor a length of the amplitude bits in a bitstream during the encoding and stop the encoding on information bits at an end of a current data unit responsive to the length reaching a threshold. In some other aspects, a transmitting device may monitor the length of the information bits and, for each data unit, determine whether a boundary is or would be reached. Responsive to determining that a boundary is or would be reached, the transmitting device may not include, before the boundary, any amplitude bits generated based on the information bits in the data unit, and instead add padding bits after a last amplitude bit before the boundary.
