1. A method for transmitting a transport block (TB) by a transmission device in a wireless communication system, the method comprising:
performing Listen Before Talk (LBT) for a plurality of subbands in a frequency domain to determine whether at least one idle subband among the plurality of subbands is idle; and
based on a determination that M subbands are idle among the plurality of subbands, performing N repeated transmissions for the TB in the M subbands, where N>1,
wherein, based on N≥M and M>1, the N repeated transmissions for the TB include M repeated transmissions performed respectively in the M subbands.
