Abstract
A coding method, a decoding method, an apparatus, and a device are provided. The method includes: coding, by a sending device, an information bit sequence to obtain a coded bit sequence, where the coded bit sequence includes an information bit, a frozen bit, a CRC check bit, and a frozen check bit; and a value of the frozen check bit and a value of the CRC check bit are obtained by using a same cyclic shift register; performing, by the sending device, polar coding and rate matching on the coded bit sequence to obtain a to-be-sent rate-matched sequence; and sending, by the sending device, the rate-matched sequence. According to the method, time and space for coding calculation and decoding calculation can be effectively reduced, and calculation complexity is reduced.
