1. A method of operating a receiving user equipment (Rx UE) performing sidelink communication in a wireless communication system, the method comprising:
receiving, by the Rx UE, sidelink control information (SCI);
receiving, by the Rx UE, data related to the SCI and generating a hybrid automatic repeat request (HARQ) acknowledgment (ACK) based on a part of a destination identifier (DST ID) of the SCI being identical to a part of ID of the RX UE; and
transmitting, by the RX UE, the HARQ ACK based on full bits of a DST ID of a medium access control (MAC) header of the data being identical to a full bits of ID of the RX UE and a full bits of a source ID (SRC ID) of a TX UE being identical to a full bits of ID of TX UE,
wherein, based on full bits of a SRC ID of the MAC header of the data being not identical to a full bits of ID of the TX UE, the RX UE skips a HARQ ACK transmission for unicast communication.
