Abstract: Methods, apparatus, and systems that relate to rate matching scheme design for polar coding, PAC coding, or other pre-transformed polar coding are described. One example method includes determining, by a first node, an output bit sequence having E bits based on an input bit sequence having K bits, wherein the output bit sequence is determined by 1) performing a polar transform with H components and 2) performing either no pre-transform or at least two pre-transform operations; wherein the polar transform is based on H polar matrices G(N0), G(N1), . . . , G(NH−1), wherein H, K and E are integers greater than 1, wherein a polar matrix G(Ni) is of size Ni. The method also includes transmitting, by the first node, a signal including the output bit sequence to a second node.

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
