Abstract
The present disclosure is for performing retransmission in a wireless communication system, and a method by which a first device operates in a wireless communication system comprises the steps of: receiving, from a second device, a first signal comprising outer- and inner-coded data; detecting information-bit-based first-type inner code blocks and parity-bit-based second-type inner code blocks by inner decoding the data in correspondence to the inner coding; confirming the location and the number of at least one bit with a possibility of error, among outer block codes, on the basis of the location of inner code blocks for which decoding has failed; deciding to request retransmission on the basis of the location and the number of the at least one bit; and requesting, to the second device, on the basis of the location and the number of the at least one bit, retransmission of at least one of an information portion or a parity portion of outer code blocks.
