Method and apparatus for transmitting data on basis of polar coding in wireless communication system

An apparatus for transmit data based on polar coding in a wireless communication system, the apparatus comprising:

• a transceiver;
• a memory;
• and
• at least one processor connected to the transceiver and the memory,
• wherein the memory is configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• transmitting first data including a plurality of information blocks, wherein each of the plurality of information blocks includes a corresponding cyclic redundancy check (CRC);
• receiving a hybrid automatic repeat request acknowledgement/negative acknowledgement (HARQ ACK/NACK) for the transmitted data;
• learning to retransmit the plurality of information blocks;
• and
• transmitting second data including the plurality of information blocks based on the HARQ ACK/NACK,
• wherein the learning comprises:
• obtaining a current state sn;
• obtaining actions to be applied to the current state sn;
• and
• selecting an action for maximizing an expected reward value Qn+1 from among the actions, wherein the expected reward value Qn+1 is obtained based on rewards R1, R2, . . . , Rn respectively corresponding to states s1, s2, . . . , sn.
