Abstract: Methods, apparatus, and systems that relate to Polarization-Adjusted Convolutional (PAC) coding with variable lengths are disclosed. In one example aspect, a method for digital communication includes determining, by a first node, an output bit sequence having E bits based on an input bit sequence having K bits. The output bit sequence is determined based on a transform that is applied prior to applying a Polar transform having a size of N. The transform is based on at least one index set that is a subset of a set of bit indices. The set of bit indices comprises all non-negative integers that are less than N and wherein K
