Abstract: A method for transmitting data on the basis of polar coding in a wireless communication system, according to the present disclosure may comprise the steps of: transmitting data including a plurality of information blocks, each of which contains a corresponding cyclic redundancy check (CRC); receiving a hybrid automatic repeat request acknowledgement/negative acknowledgement (HARQ ACK/NACK) of the transmitted data; performing learning in order to retransmit the plurality of information blocks; and retransmitting the plurality of information blocks on the basis of the HARQ ACK/NACK, wherein the step of performing learning comprises the steps of: obtaining current state sn; obtaining actions to be applied to current state sn; and selecting, from the actions, an action maximizing expected reward value Qn+1, wherein expected reward value Qn+1 is obtained on the basis of rewards R1, R2, . . . , Rn corresponding to states s1, s2, . . . , sn, and the plurality of information blocks is retransmitted on the basis of the selected action.
