A first device may encode a first bit sequence of length K including a first information block, a second information block, a first cyclic redundancy check (CRC) for the first information block, and a second CRC for the second information block, based on a polar code of size; transmit a first signal based on the encoded first bit sequence; receive first hybrid automatic repeat request acknowledgement/negative-acknowledgement (HARQ ACK/NACK) information for the first bit sequence; divide the second information block into a first sub information block and a second sub information block and generate a third CRC for the first sub information block based on the first HARQ ACK/NACK information including information indicating failure of the transmission of the second information block; encode a second bit sequence including the third CRC based on the polar code; and transmit a second signal based on the encoded second bit sequence.
