This application provides coding/decoding methods and communications apparatuses thereof. In an implementation, a coding method includes: obtaining a first information bit sequence; determining a first frozen bit sequence based on a probability distribution value Pof the first information bit sequence, determining a check bit sequence based on a second information bit sequence, where the second information bit sequence is the first information bit sequence or a sequence obtained after a pre-transformation operation is performed on the first information bit sequence, obtaining a first bit sequence based on the second information bit sequence, the check bit sequence, and the first frozen bit sequence, where the first bit sequence includes bits in the second information bit sequence.

Coding method, decoding method, and communications apparatus

This application discloses a communication method that comprises obtaining first data, where the length of the first data is A; compressing the first data into second data, where the length of the second data is C; and generating third data based on the second data, where the third data includes the second data and (T−C+p) alignment bits. T is a threshold in the J thresholds that is greater than or equal to C and the closest to C. The J thresholds correspond to A and are greater than 0, with J being a positive integer greater than or equal to 2. p is a quantity of auxiliary check bits and is an integer greater than or equal to 0. The communication method further comprises performing channel encoding on the third data to obtain fourth data and sending the fourth data.
