1. An operating method of a receiving device configured to perform a hybrid automatic repeat and request (HARQ) process, the operating method comprising:
receiving data from a target transmitting device via a sidelink channel;
determining whether to request transmission of replacement data for the data from the target transmitting device according to a performance result of the HARQ process on the received data; and when transmission of the replacement data is requested, transmitting to the target transmitting device a replacement data request signal distinct from an acknowledge (ACK) signal and a negative-ACK (NACK) signal,
wherein the replacement data has a second coding rate lower than a first coding rate of data transmitted in response to the NACK signal.
