    摘要: A collaborative MIMO method using a sounding channel in a multi-cell environment is disclosed. The method includes acquiring, by a first base station providing a service for a first cell, first CSI of a first downlink channel between the first base station and a mobile station, transmitting, to a second base station, a signal including information requesting that the second base station providing a service for a second cell acquire second CSI of a second downlink channel between the second base station and the mobile station, and acquiring, by the second base station, the second CSI. The mobile station is served by the first base station.

    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.
