Abstract: The present specification provides an operation method of a base station for transmitting and receiving a signal using non-orthogonal multiple access (NOMA) in a wireless communication system. The method comprises the steps of: setting a first modulation scheme and a first transmission power for a first signal to be transmitted to a first user equipment; setting a second modulation scheme and a second transmission power for a second signal to be transmitted to a second user equipment; overlapping the first signal and the second signal; and transmitting a signal obtained by overlapping, wherein the transmission of the overlapped signal uses an overlapping constellation defined in advance or configured by a predetermined notation.

Abstract: A method of receiving a downlink channel, which is received by a user equipment from an eNB in a wireless communication system, is disclosed in the present specification. Specifically, the method includes the steps of receiving a downlink control channel for receiving a DM-RS (demodulation reference signal) based downlink data channel from the eNB, and receiving the DM-RS based downlink data channel using DM-RS configuration information included in the downlink control channel. In this case, if single-codeword transmission via the DM-RS based downlink data channel is indicated by the downlink control channel, the DM-RS based downlink data channel is received using a transmission diversity scheme. If two-codewords transmission via the DM-RS based downlink data channel is indicated by the downlink control channel, the DM-RS based downlink data channel is received using a spatial multiplexing scheme.
