Abstract: Embodiment techniques map parity bits to sub-channels based on their row weights. The row weight for a sub-channel may be viewed as the number of “ones” in the corresponding row of the Kronecker matrix or as a power of 2 with the exponent (i.e. the hamming weight) being the number of “ones” in the binary representation of the sub-channel index (further described below). In one embodiment, candidate sub-channels that have certain row weight values are reserved for parity bit(s). Thereafter, K information bits may be mapped to the K most reliable remaining sub-channels, and a number of frozen bits (e.g. N−K) may be mapped to the least reliable remaining sub-channels. Parity bits may then mapped to the candidate sub-channels, and parity bit values are determined based on a function of the information bits.

Abstract: A communication method and a communication apparatus are provided. The method includes: a first device first checks a first bit sequence based on a cyclic redundancy check (CRC) code, to obtain a second bit sequence; then divides the second bit sequence into P bit sequences; and generates Q codewords based on the P bit sequences, and sends the Q codewords to a second device through P transport layers. P represents a quantity of transport layers of the first device, P is greater than or equal to 2, and Q is an integer greater than or equal to 2. The first device first checks the first bit sequence based on the CRC code, and then divides the second bit sequence into the P bit sequences, that is, performs code rate allocation.
