Abstract
A method and an apparatus for transmitting and receiving a signal using interference alignment in a multi-cellular network are provided. The method includes determining a total number Sof effective Inter-Cell Interference (ICI) channels of a j-th cell, determining a number tof effective ICI channels caused by each of other Base Stations (BSs) and a number nof ICI channels aligned to each effective ICI channel, acquiring information about a channel matrix between users of the j-th cell and each BS, determining effective ICI channels reaching from the other BSs to users of the j-th cell and a receive beamforming matrix by reference to t, nand information about the channel matrix, transmitting feedback information indicating the channel matrix and the receive beamforming matrix to the BS of the j-th cell, and receiving a signal from the BS of the j-th cell using the determined receive beamforming matrix.
