Abstract: This application provides a data processing method, an apparatus, and a device, to implement an encoding method supporting blind decoding. When a quantity of information bits is large, the information bits need to be carried in a plurality of to-be-encoded blocks. In this case, during to-be-encoded block division (that is, code block division), a part of information bits in a subsequent code block may be moved to a previous code block.

Abstract: A polar code construction method and an apparatus. A communication apparatus obtains a reliability weight sequence, and determines a first threshold that indicates a weight of lowest reliability of a subchannel corresponding to an information bit. The communication apparatus determines a non-pre-frozen subchannel corresponding to a content value greater than or equal to the first threshold in the reliability weight sequence as the subchannel corresponding to the information bit based on the first threshold, and performs polar coding on the information bit based on the subchannel corresponding to the information bit.

Abstract: This application provides a channel encoding method, an encoding apparatus, and a system. A bit sequence X1N is output by using X1N=D1N FN, where D1N is a bit sequence obtained after an input bit sequence u1N is encoded based on locations of K to-be-encoded information bits in an encoding diagram that has a mother code length of N, u1N is a bit sequence obtained based on the K to-be-encoded information bits, and FN is a Kronecker product of log2 N matrices F2. In the foregoing technical solution, in particular, a design considers that the locations of the K to-be-encoded information bits in the encoding diagram that has a mother code length of N include a row location index set H of the information bits in the encoding diagram and a layer location index set M of the information bits in the encoding diagram, where 0≤H≤N, and 0

Abstract: This application provides a polar encoding method and apparatus. The method can include obtaining a basic sequence, where the basic sequence includes N0 subchannel numbers. The method can also include sequentially reading first subchannel numbers from the basic sequence, and sequentially reading 2m second subchannel numbers from the basic sequence starting from an Mth subchannel number based on the first subchannel number read each time; and adding q*N0 to each of the 2m second subchannel numbers to obtain 2m third subchannel numbers. Furthermore, the method can include constructing a polar code by using subchannels corresponding to the 2m third subchannel numbers as information bits. A polar code with another code length is constructed based on a sequence with a length of N0. A length of a polar code that needs to be stored is therefore reduced, which reduces complexity and is also easy to implement.
