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.

Abstract: The present application provides a method for allocating resources in a wireless communication system using multiple antennas. The method for allocating resources comprising: transmitting a reference signal to first-type terminals based on type information of a plurality of terminals; receiving channel estimation information from the first-type terminals that have received the reference signal; generating beams based on the received channel estimation information; and allocating resources for the generated beams. First-type beams for the first-type terminals are primarily generated and allocated, and on the basis of the generated first-type beams, second-type beams for second-type terminals may be non-orthogonally generated and allocated when the resources for the beams are allocated.

Abstract: The present invention relates to a method of transmitting and receiving a signal in a wireless communication system. In particular, in a time division multi-cell cooperative communication system, a base station may receive a reference signal, estimate a channel of each user terminal based on the reference signal, and determine a transmission and reception filter based on estimated channel information. The base station and a cooperative base station that cooperates with the base station may mutually exchange the reference signal and average signal power information on a terminal and determine the transmission and reception filter based on exchanged information.

Abstract: The present invention relates to a method for transmitting and receiving signals in a wireless communication system. Specifically, in a multi-cell cooperative communication system, a base station can form cooperative detection user set information by detecting a terminal within a cell and form cooperative processing user set by receiving the cooperative detection user set information of a neighboring base station. At this time, the base station acquires information about a base station adjacent to the neighboring base station and designs an efficient filter in transmitting and receiving signals of terminals between the base stations, thereby being capable of removing inter-cell interference signals.
