Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. An apparatus for encoding a polar code, the apparatus comprising:
a transceiver; and
at least one processor, wherein the at least one processor is configured to:
obtain state-indicator information indicating a state of each of bits included in the polar code based on an index set of the bits,
identify a weak-bit or a second weak-bit corresponding to a parity bit candidate position preset according to an interconnection within a parity-check (PC)-chain of the polar code and between PC-chains of the polar code, based on a number of weak-bits determined according to the state-indicator information and a number of bits to be used as parity bits,
when a number of the parity bits identified according to the interconnection within the PC-chain of the polar code and between the PC-chains of the polar code corresponds to the number of bits to be used as the parity bits, terminate identification of the weak-bit or the second weak-bit as the parity bit,
obtain a polar code including the identified parity bit, and
transmit, via the transceiver, a signal comprising the polar code to an apparatus comprising a decoder for decoding the polar code.
