Title: METHOD FOR TRANSMITTING OR RECEIVING DOWNLINK SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Abstract:
The method, according to one embodiment of the present invention, by which in a wireless communication system a base station transmits signals to a plurality of terminals on the basis of non-orthogonal multiple access (NOMA), comprises the steps of: mapping first information bits for a first terminal and second information bits for a second terminal onto a first layer for the NOMA; modulating the first information bits and the second information bits which have been mapped on the first layer; and transmitting modulation symbols, which have been generated as a result of the modulation, to the first terminal and the second terminal, wherein the base station may map the first information bits and the second information bits onto the first layer, at a bit level before the modulation symbols have been generated.
