description An operation method of a transmitting apparatus in a wireless communication system includes transmitting, to a receiving apparatus, reverse mapping flag information indicating a direction of mapping data symbols to one or more subcarriers included in a resource block allocated to the receiving apparatus; mapping the data symbols to the one or more subcarriers of the resource block based on the reverse mapping flag information; and transmitting the resource block to the receiving apparatus. According to the embodiments of the present disclosure, the amount of subcarrier phase shift noises due to an SFO occurring in proportion to synchronization impairment and subcarrier index can be reduced in a multi-carrier communication system, thereby increasing data retransmission efficiency.
