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.

Abstract: Provided are a data transmission method and device and a storage medium. The method includes selecting a first number of bits from a to-be-transmitted information bit sequence to form a to-be-coded bit sequence of a retransmitted data block; polar-coding the to-be-coded bit sequence of the retransmitted data block to obtain a coded bit sequence; combining the coded bit sequence with a coded first-transmission data block to obtain the current to-be-transmitted data block; and performing digital baseband modulation on the current to-be-transmitted data block and then sending the modulated current to-be-transmitted data block to a second communication node.

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 c having K bits, wherein the output bit sequence is determined based on an output of a polar transform and an output of a repetition operation, and wherein the input of the repetition operation is a portion of a bit sequence before the polar transform. 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

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.
