Polar code encoding method and device

A method for Polar code encoding, comprising:

• representing each Polar code group in m Polar code groups by a common Frozen bit set, wherein Polar codes in each Polar code group have a same code length and different code rates, and m is greater than or equal to 2;
• obtaining a Frozen bit set corresponding to each Polar code in the Polar code group based on the common Frozen bit set corresponding to the Polar code group;
• and
• performing Polar code encoding on information to be encoded based on the Frozen bit set corresponding to each Polar code in the Polar code group.

An apparatus for Polar code encoding, comprising a process and a storage having processor-executable instructions stored thereon that, when executed by the processor, cause the apparatus to:

• represent each Polar code group in m Polar code groups by a common information bit set, wherein Polar codes in each Polar code group have a same code length and different code rates, and m is greater than or equal to 2;
• obtain an information bit set corresponding to each Polar code in the Polar code group based on the common information bit set corresponding to the Polar code group;
• and
• perform Polar code encoding on information to be encoded based on the information bit set corresponding to each Polar code in the Polar code group.
