1. A method for transmitting and receiving, by a first user equipment (UE), data using a non-orthogonal multiple access (NOMA) in a wireless communication system, the method comprising:receiving, from a base station, first downlink control information (DCI) including information related to physical downlink shared channel (PDSCH) scheduling of the first UE;
receiving, from the base station, second DCI including information related to PDSCH cancellation of a second UE;
receiving, from the base station, a superposition signal including a PDSCH of the first UE and a PDSCH of the second UE; and
decoding the PDSCH of the first UE by cancelling the PDSCH of the second UE from the superposition signal based on the received second DCI,
wherein the first DCI and the second DCI are distinguished through a specific indicator, and
wherein each of the first DCI and the second DCI includes a field for the specific indicator.
