Abstract: A method for receiving signals by a first terminal in a wireless communication system supporting non-orthogonal multiple access (NOMA), according to one embodiment of the present invention, comprises the steps of: obtaining downlink control information with respect to a second terminal which is NOMA-paired with the first terminal; receiving NOMA signals in which a first physical downlink shared channel (PDSCH) with respect to the first terminal and a second PDSCH with respect to the second terminal are multiplexed by different transmission power values; and removing interference by the second PDSCH from the NOMA signals on the basis of the downlink control information with respect to the second terminal. In the step of removing the interference by the second PDSCH, if the second PDSCH is re-transmitted to the second terminal by an HARQ process, the interference by the second PDSCH can be removed by reusing predetermined information obtained by the first terminal at the time of initial transmission with respect to the HARQ process.

Abstract: The present specification proposes a method of reporting channel quality information (CQI) by a user equipment (UE) to a base station (BS) in a wireless communication system. Specifically, the method includes the step of receiving a cell specific reference signal from the BS; calculating the CQI using the cell specific reference signal on the assumption that a specific number of resource elements (REs) for a demodulation-reference signal (DM-RS) exists; and reporting the CQI to the BS. Especially, if a most recent reported rank is 3 or 4, the specific number of REs for the DM-RS is assumed as a specific value, which is different from a minimum number of REs for the DM-RS or a maximum number of REs for the DM-RS.
