Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A first device configured to transmit, to a second device, a signal based on polar coding, the first device 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 by the at least one processor, cause the at least one processor to perform operations 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.
