Abstract: The present application provides a method for a multi-user multi-stream supporting base station transmitting a signal to a terminal. The method comprising: estimating channel information of a first terminal by receiving a reference signal from the first terminal; and by using the estimated channel information, transmitting a plurality of beams to the first terminal based on a non-orthogonal multiple access scheme. When transmitting the plurality of beams to the first terminal based on the non-orthogonal multiple access scheme, a plurality of virtual terminals of the first terminal are generated, and a signal for a first virtual terminal among the plurality of virtual terminals are allocated to a first beam and transmitted, and a signal for a second virtual terminal among the plurality of virtual terminals are allocated to a second beam and transmitted.
