Abstract: An operating method of a receiving device may include receiving data from a target transmitting device of at least one 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 a hybrid automatic repeat request (HARQ) process on the 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.
