Abstract: A method for reducing inter-cell interference and a method for transmitting a signal by a collaborative MIMO scheme, in a communication system having a multi-cell environment are disclosed. An example of a method for transmitting, by a mobile station, precoding information in a collaborative MIMO communication system includes determining a precoding matrix set including precoding matrices of one more base stations including a serving base station, based on signal strength of the serving base station, and transmitting information about the precoding matrix set to the serving base station. A mobile station in an edge of a cell performs a collaborative MIMO mode or inter-cell interference mitigation mode using the information about the precoding matrix set collaboratively with neighboring base stations.

Abstract: A method for avoiding an inter-cell interference (ICI) in a multi-cell environment is disclosed. The method includes restricting the use of a PMI in an interfering cell so as to improve a reception performance of a mobile station located at an interfered cell edge. The mobile station measures a restricted-PMI of the interfering cell, which is prohibited from use in the interfering cell, and transmits the measured restricted PMI to the interfering cell. The use of the restricted PMI is prohibited from use in a mobile station in the interfering cell.

Abstract: A method for transmitting a precoded signal in a collaborative multiple-input multiple-output (MIMO) communication system is described. A method for receiving a precoded signal in a MIMO communication system includes estimating, by a mobile station, channels for one or more base stations through signals received from the one or more base stations including a serving base station, transmitting precoding matrix indexes of the one or more base stations determined based on the estimated channels to the serving base station, and receiving signals precoded by the one or more base stations based on the precoding matrix index.
