1. A method of transmitting, by a first device to a second device, a signal based on polar coding, the method comprising:
encoding a first bit sequence having a length of K and 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 with a size of N;
transmitting a first signal based on the encoded first bit sequence;
receiving first hybrid automatic repeat request acknowledgement/negative-acknowledgement (HARQ ACK/NACK) information for the first bit sequence;
based on that the first HARQ ACK/NACK information includes information indicating failure in transmission of the second information block, segmenting the second information block into a first information sub-block and a second information sub-block and generating a third CRC for the first information sub-block;
encoding a second bit sequence having a length of L and including the third CRC based on the polar code; and
transmitting a second signal based on the encoded second bit sequence.
