Abstract
Embodiments of the disclosure provide a device in a communication system or a broadcasting system that may comprise: a memory, at least one transceiver and at least one processor comprising processing circuitry. At least one processor, individually and/or collectively, may be configured to: receive a signal including bits encoded based on polar codes; identify a polar code configuration for at least one information bit and at least one frozen bit of the signal; and decode the signal based on the configuration of the polar codes.
Claims20
A method performed by a device in a communication system or a broadcasting system, comprising:
- receiving a signal including bits encoded based on polar codes;
- identifying a polar code configuration for at least one information bit and at least one frozen bit of the signal;
- and
- decoding of the signal, based on the polar code configuration,
- wherein decoding of information bit among the at least one information bit is performed based on at least one value of at least one constraint bit, and
- wherein the at least one constraint bit includes at least one of a parity bit or a frozen bit after the information bit in a decoding order.
An apparatus in a communication system or a broadcasting system, comprising:
- memory storing instructions;
- at least one transceiver;
- and
- at least one processor, comprising processing circuitry,
- wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the apparatus to:
- receive a signal including bits encoded based on polar codes;
- identify a polar code configuration for at least one information bit and at least one frozen bit of the signal;
- and
- decode the signal, based on the polar code configuration;
- wherein decoding of an information bit among the at least one information bit is performed based on at least one value of at least one constraint bit;
- and
- wherein the at least one constraint bit includes at least one of a parity bit or a frozen bit after the information bit in the decoding order.
