Classification: CPC H | IPC H

Claim 10:
11. A polar code encoding apparatus, comprising:
at least one processor; and
at least one non-transitory memory coupled to the at least one processor and storing program instructions, wherein the at least one processor is configured to execute the program instructions to cause the polar code encoding apparatus to:
obtain K information bits to be encoded, wherein K is a positive integer;
determine K information bit positions;
map the K information bits to be encoded to the K information bit positions to obtain a first bit sequence, wherein a length of the first bit sequence is N, N is a positive integer power of 2, and the first bit sequence comprises fixed bits and the K information bits to be encoded;
determine a second bit sequence based on the first bit sequence and an upper triangular matrix, wherein the upper triangular matrix is a matrix having N rows and N columns; perform polar code encoding on the second bit sequence to obtain an encoded sequence; and
transmit the encoded sequence to a device to be decoded.
