Abstract
An encoding method for encoding input information bits using an encoder implemented with concatenation of a CRC-α coder and a polar coder is provided. The method includes performing Cyclic Redundancy Check (CRC) coding on as many information bits as a determined number of CRC coding bits among input information bits and performing polar coding on the CRC-coded information bits and other information bits than the CRC-coded information bits.
Claims20
A method performed by an apparatus in a wireless communication system, the method comprising:
- identifying information bits;
- determining a subset of the information bits to be applied as an error check code among the identified information bits, based on an information set of an error correction code;
- performing an error check coding based on the determined subset of the information bits;
- performing an error correction coding based on the information set of the error correction code, the error check coded subset of the information bits and one or more bits of the identified information bits;
- and
- transmitting the error correction coded information bits.
An apparatus in a wireless communication system, the apparatus comprising:
- a controller configured to:
- identify information bits,
- determine a subset of the information bits to be applied as an error check code among the identified information bits, based on an information set of an error correction code,
- perform an error check coding based on the determined subset of the information bits,
- perform an error correction coding based on the information set of the error correction code, the error check coded subset of the information bits and one or more bits of the identified information bits, and
- transmit the error correction coded information bits.
