Abstract: Embodiments of the present invention disclose a polar code processing method and communications device. The method includes: obtaining, based on a target coded bit quantity M and preset first mapping relationship information, a first sequence number set of M uncoded bits that is corresponding to the target coded bit quantity M, the first mapping relationship information is used to indicate a one-to-one correspondence between a plurality of coded bit quantities and a plurality of uncoded bit sequence number sets, the M uncoded bits include K information bits, and M target coded bits are obtained after polar encoding is performed on the M uncoded bits; and selecting, from the first sequence number set of the M uncoded bits according to a preset first selection rule, K sequence numbers as a sequence number set of the K information bits.

Abstract: Embodiments of this application disclose provides a low density parity check (LDPC) channel encoding method for use in a wireless communications system. A communication device encodes an input bit sequence by using a LDPC matrix, to obtain an encoded bit sequence for transmission. The LDPC matrix is obtained based on a lifting factor Z and a base matrix. Embodiments of the application provide eight particular designs of the base matrix. The encoding method provided in the embodiments of the application can be used in various communications systems including the fifth generation (5G) telecommunication systems, and can support various encoding requirements for information bit sequences with different code lengths.
