    摘要: A method of controlling interference in a wireless communication system is disclosed. A method for controlling interference by a transmitter of a wireless communication system with multiple antennas comprises generating a base codebook subset including at least one precoding matrix selected from a base codebook; transmitting a base codebook subset indication, which represents the at least one precoding matrix included in the base codebook subset, to a receiver; and precoding data using the base codebook subset or the base codebook.

    摘要: 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.

    摘要: 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.
