Abstract: A method and an apparatus for encoding a polar code concatenated with a cyclic redundancy check (CRC), where M bits are selected from K bits in the sequence to perform CRC encoding. The M bits are determined based on reliability of K polarized subchannels on which the K bits are placed and/or row weights of K rows, in a first matrix, corresponding to the K polarized subchannels on which the K bits are placed. The first matrix is an encoding matrix of polar encoding. Polar encoding is performed on the K bits and obtained CRC check bits. An encoded codeword is output.

Abstract: The disclosure provides image encoding methods and apparatuses. One example encoding method includes: obtaining a one-dimensional sequence of quantized coefficients of an image; obtaining a run-length value sequence and a level value sequence based on the one-dimensional sequence of the quantized coefficients; obtaining an updated second distribution probability of each level value in the level value sequence based on the m first distribution probabilities, the n second distribution probabilities, and a preset mapping rule; and performing encoding based on the level value sequence and the updated second distribution probability of each level value in the level value sequence to obtain and output encoded image data.

Abstract: Embodiments of the present disclosure disclose obtaining to-be-encoded first information that includes first and second information bit sets. The bits included in the first information bit set are obtained through decoding by a plurality of terminal devices. The bits included in the second information bit set are able to be obtained through decoding by some of the plurality of terminal devices. Polar encoding is first performed on the first information bit set to obtain first encoded information. Polar encoding is then performed on the second information bit set based on the first encoded information to obtain second encoded information.

Abstract: A method and an apparatus for encoding and for decoding a polar code to reduce complexity and improve speed. For encoding, information bits are obtained, an original kernel matrix is adjusted to construct one or more kernel matrices, an appropriate target kernel matrix is selected from the one or more kernel matrices, and polar encoding is performed on the information bits based on the target kernel matrix. For decoding, a to-be-decoded sequence is obtained, and the to-be-decoded sequence is decoded based on a plurality of trellises, where intermediate results obtained in different decoding stages may be reused. For example, in a (t+i)th stage of decoding, an intermediate result obtained in a tth stage of decoding is reused.

Abstract: This application provides an information transmission method and an apparatus. In the method, a sending device sends a first bit sequence to a receiving device. Optionally, the first bit sequence is an information bit sequence, or the first bit sequence is an information bit sequence obtained through first encoding. The sending device receives a second bit sequence from the receiving device. The sending device sends a first code block to the receiving device, where the first code block is obtained based on a first error pattern and a first check matrix. The first error pattern is determined based on the second bit sequence and the first bit sequence.
