A coding method may include obtaining, based on a sequence whose length is 2n′, a mother code sequence used for coding, where the sequence whose length is 2n′ includes 2n′ sequence numbers, a length of the mother code sequence is 2n, the mother code sequence includes 2n sequence numbers, the 2n sequence numbers are some or all of the 2n′ sequence numbers, n′ is a natural number, and n is a natural number less than or equal to n′. The method may also include coding an input to-be-coded bit by using the mother code sequence. According to this method, a system may store one or more long sequences, and then obtain a required mother code sequence from one of the long sequences according to a coding requirement, thereby reducing storage overheads of the system.

Abstract: This application provides a polar code transmission method and apparatus. The method includes: transforming a to-be-processed bit sequence at two or more different granularities, where each specific manner at a first granularity is used to implicitly indicate one value in one level of time sequence information, and each specific manner at a second granularity is used to implicitly indicate one value in another level of time sequence information; and sending the transformed (processed) bit sequence, so that different encoded bit sequences can be obtained, and more versions of time sequence information can be implemented, thereby meeting a requirement of transmission in a plurality of levels of time sequences.
