Polar coding method, apparatus, and device

A polar coding apparatus, wherein the apparatus comprises:

• at least one memory storing instructions;
• and
• at least one processor in communication with the at least one memory, wherein the instructions are for execution by the at least one processor to perform operations comprising:
• determining a length L of a second sequence;
• obtaining the second sequence that is used as a mother code sequence when coding into a target polar code is performed, wherein the second sequence comprises L sequence numbers from 0 to L−1, wherein an order of the L sequence numbers in the second sequence is the same as an order of the L sequence numbers in a maximum mother code sequence, wherein L is less than or equal to N, wherein L and N are positive integers, wherein N is a length of the maximum mother code sequence, and wherein the maximum mother code sequence is stored in a first manner or a second manner;
• and
• performing polar coding on to-be-coded bits based on the second sequence.

A non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores computer executable program code, and the program code comprises an instruction for performing operations comprising:

• determining a length L of a second sequence;
• obtaining the second sequence that is used as a mother code sequence when coding into a target polar code is performed, wherein the second sequence comprises L sequence numbers from 0 to L−1, wherein an order of the L sequence numbers in the second sequence is the same as an order of the L sequence numbers in a maximum mother code sequence, wherein L is less than or equal to N, wherein L and N are positive integers, wherein N is a length of the maximum mother code sequence, and wherein the maximum mother code sequence is stored in a first manner or a second manner;
• and
• performing polar coding on to-be-coded bits based on the second sequence.
