    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.

    Abstract: An encoding method, a decoding method, and a communication apparatus. The communication apparatus obtains an information bit sequence with a length K. A length K1 of a first sequence based on K or M is determined, where M is a quantity of modulation symbols. A first vector is obtained based on K, K1, and a predefined sequence. A length of the first vector is 2JM, J is a modulation order, the first vector indicates J coding sub-blocks, the J coding sub-blocks separately belong to a first-type sub-block including at least one coding sub-block or a second-type sub-block including at least one coding sub-block. The communication apparatus determines frozen bit locations in the first-type sub-block and information bit locations in the second-type sub-block and encodes the information bit sequence based on the frozen bit locations in the first-type sub-block, the information bit locations in the second-type sub-block, and the first vector.

    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.
