Abstract: A communication method and a communication apparatus. In the method, a transmit end obtains to-be-encoded information, where the to-be-encoded information includes k bits, and k is a positive integer; the transmit end determines that a quantity of code blocks is C, and C is a positive integer; the transmit end performs polar encoding on the to-be-encoded information based on C, to obtain C encoded code blocks; and the transmit end sends the C encoded code blocks. In some implementations, the transmit end determines, based on k and a target bit rate, that the quantity of code blocks is C. In some implementations, the transmit end obtains the C encoded code blocks in a code block coupling manner.

Abstract: Embodiments of this application provide an information transmission method and an apparatus. The transmit end sends a first coded bit sequence based on a to-be-transmitted coded bit sequence. The receive end receives and decodes a first to-be-decoded sequence, and sends first indication information if the decoding fails, where the first indication information includes information about a location, in the to-be-transmitted coded bit sequence, of at least one sent coded bit in the to-be-transmitted coded bit sequence. The transmit end receives the first indication information, and sends a second coded bit sequence based on the first indication information, where the second coded bit sequence includes the at least one sent coded bit in the to-be-transmitted coded bit sequence and/or at least one unsent coded bit in the to-be-transmitted coded bit sequence.

Abstract: A method comprises: obtaining a coded bit sequence by performing PC-polar coding on information bits based on first constructor parameters; and sending the coded bit sequence. A check equation of the first constructor parameters includes a first element representing a check-required information bit position and a second element representing a check bit position, the first element corresponds to a first vector (V1) in a generator matrix for PC-polar codes, the second element corresponds to a second vector (V2) in the generator matrix, and if a first Hamming weight (HW1) of V1 is the same as a second Hamming weight (HW2) of V2, then a third Hamming weight (HW3) of an addition modulo 2 vector is greater than HW1 and greater than HW2, or if HW1 is different from HW2, then HW3 is greater than a smaller one of the HW1 and HW2.

Abstract: A decoding method includes: decoding first to-be-decoded information based on a first decoder to obtain a first decoding result that includes first soft information or a first hard output; and correcting the first decoding result based on a first correction model to obtain a corrected first decoding result of the first to-be-decoded information. The first correction model is obtained through training based on training data that includes a training decoding result and a corrected training decoding result. The training decoding result is a decoding result obtained after the first decoder decodes training to-be-decoded information, and the corrected training decoding result is a corrected decoding result corresponding to the training decoding result. In this way, after a decoder performs decoding, a decoding result can be corrected based on a correction model.
