Abstract: Methods, apparatus, and systems that relate to rate matching scheme design for polar coding, PAC coding, or other pre-transformed polar coding 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, wherein the output bit sequence is determined by performing a polar transform with H components and a pre-transform; wherein the polar transform is based on H polar matrices G(N0), G(N1), . . . , G(NH−0), wherein E, K, H are integers greater than 1, wherein a polar matrix G(N0) is of size Ni. The method also includes transmitting, by the first node, a signal including the output bit sequence to a second node.
