Polar code encoding method and apparatus

A polar code encoding apparatus, comprising:

• an obtaining unit, configured to obtain a basic sequence, wherein the basic sequence is a sequence obtained by sorting sequence numbers of polarized channels in descending order or ascending order of reliability, and a length of the basic sequence is L1;
• and
• a processing unit, wherein the processing unit is configured to:
• determine, based on the basic sequence and a maximum encoding length L2 supported by a receiving device, M segments of an information bit sequence, wherein the M segments of an information bit sequence comprises N bits, wherein the information bit sequence before encoding comprises K bits;
• separately encode the M segments by using a first encoding scheme, to obtain the M encoded segments;
• and
• perform polar code encoding on the M encoded segments.

A non-transitory computer-readable storage medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:

• obtaining a basic sequence, wherein the basic sequence is a sequence obtained by sorting sequence numbers of polarized channels in descending order or ascending order of reliability, and a length of the basic sequence is L1;
• determining, based on the basic sequence and a maximum encoding length L2 supported, M segments of an information bit sequence, wherein the M segments of an information bit sequence comprises N bits, wherein the information bit sequence before encoding comprises K bits;
• separately encoding the M segments by using a first encoding scheme, to obtain the M encoded segments;
• and
• polar encoding on the M encoded segments.
