INTERFERENCE ALIGNMENT METHOD AND DEVICE IN CELLULAR NETWORK

摘要

According to one aspect of the present invention, the present invention provides a method for allowing a base station, which receives signals from one or more terminals, to align receiving signals and interference signals in a wireless access system. Said method comprises the steps of: receiving the receiving signals and the interference signals, wherein said receiving signals are signals which are received from terminals that belong to a serving cell of said base station, and said interference signals are signals which are received from terminals that belong to neighbor cells of said base station; dividing a signal space for receiving said receiving signals and said interference signals into one or more signal spaces of size N; and arranging K receiving signals of said receiving signals in each of said divided signal spaces, wherein said K receiving signals arranged in each of said divided signal spaces are orthogonal to each other.
