摘要： Provided are a mobile station that may determine a Precoding Matrix Index (PMI) of a serving channel, generate Channel State Information (CSI) based on only interference channels, and feed back the PMI and the CSI to a serving base station, a base station that may design a precoding vector based on the PMI and the CSI, and an operation of the mobile station. Also, provided are a mobile station that may determine a PMI based on only interference channels, generate CSI of a serving channel, and feed back the PMI and the CSI to a serving base station, a base station that may design a precoding vector based on the PMI and the CSI, and an operation method of the mobile station.

摘要： The invention relates to a base station in a wireless communication system comprising a mobile station and the base station. The base station comprises a CSI receiving unit configured to receive Channel State Information (CSI) of a first channel between the base station and a first mobile station from the first mobile station, the first mobile station being located in a cell where the base station belongs, a PMI receiving unit configured to receive a Precoding Matrix Index (PMI) which is determined by a second mobile station based on a second channel between the base station and the second mobile station, the second mobile station being located in an adjacent cell and a precoder configured to design a precoding vector based on the CSI and the PMI.
