Abstract: A method for transceiving, by a network, a signal through at least two streams in a wireless communication system, includes measuring a channel state for the at least two streams by using a reference signal, determining at least one stream pair including a transmission stream and a reception stream based on the measured channel state, initiating a direction of one or more streams of the at least one stream pair, and transceiving the signal based on the one or more streams of the at least one stream pair.

Abstract: A method is provided for determining, by a base station, a Virtual-Multiple-Input Multiple-Output (V-MIMO) cluster in a wireless communication system. The base station determines a transmission efficiency of a temporary cluster and selects one or more entry candidate nodes contained in the temporary cluster. The base station determines an entry transmission efficiency. The entry transmission efficiency is a transmission efficiency when the entry candidate node enters a V-MIMO unit cluster. The base station determines whether to make the entry candidate node enter the V-MIMO unit cluster by comparing the entry transmission efficiency with the transmission efficiency of the temporary cluster.

Abstract: A method is provided for transceiving a signal through at least two data streams in a wireless communication system. A first base station measures a wireless channel state for a link with a second base station by using an orthogonal pilot signal. The first base station receives channel status information related to a link of a first mobile station from the first mobile station, channel status information related to a link of a second mobile station from the second mobile station, and channel status information related to a device-to-device (D2D) link from the second mobile station. The D2D link is a channel link between the mobile stations. The first base station exchanges the received channel status information with the second base station, the first mobile station and the second mobile station using a broadcast signal, and determines data stream directions of the first base station and the second base station.
