Abstract: Disclosed is a method for ergodic interference alignment with delayed feedback. A method for ergodic interference alignment with delayed feedback on a wireless network including a plurality of transmitters and a plurality of receivers comprises the steps of allowing the transmitters to operate in a first transmission mode of transmitting data to the receivers in a first transfer phase; allowing the transmitters to receive delayed channel state information as feedback from the receivers; allowing the transmitters to determine whether a channel matrix satisfies a predefined channel pattern using the delayed channel state information; and allowing the transmitters to operate in a second transmission mode of transmitting, to the receivers, secondary data required to remove interference in a second transfer phase, when the channel matrix satisfies the predefined channel pattern.

Abstract: PURPOSE: An apparatus and a method for in a mobile communication system including distributed small-sized stations are provided to effectively control inter-cell interference while letting base stations partly cooperate with each other by exchanging a little information. CONSTITUTION: Distributed small-size stations (100,200,300) consist of one super node and at least two normal nodes. Each of the normal nodes processes first data and transmits the first data, Each of the normal nodes outputs second data that is independent from the first data to the super node. The super node receives the second data from each of the normal nodes and processes third data and transmits the third data.
