Abstract (en)
[origin: WO2021105548A1] A method, an apparatus and a computer program relating to a design of fixed length coding scheme for probabilistic shaping applied to new radio (NR) physical layer are disclosed, wherein an initialization of a lookup table with inconstancies is generated by assigning a plurality of index labels, the index labels representing an input to a distribution matcher, to a plurality of output labels of the distribution matcher, the output labels comprising a plurality of output symbols; wherein each of the plurality of output labels are capable of being assigned to two or more of the index labels, to merge the two or more index labels together, and further to shape an output probability distribution of the plurality of output symbols to be closer to a channel probability distribution associated with an error of a channel used for transmission or reception; wherein at least one of an encoding or decoding operation is performed using the lookup table with inconstancies to encode the input to the distribution matcher or to decode the plurality of output symbols.
