Abstract:
1. A method of operating a Mobile Station (MS) capable of selecting a precoding matrix in a multi-antenna wireless communication system, the method comprising: receiving, from a serving Base Station (BS), information on a precoding matrix of which use is prohibited and a precoding matrix to be used by a neighbor BS; estimating, from a pilot signal, an interference signal for the precoding matrix to be used by the neighbor BS; and selecting the precoding matrix to be used by the serving BS by considering the estimated interference signal from the remaining precoding matrices except for the precoding matrix of which use is prohibited among precoding matrices used by the serving BS and by selecting a precoding matrix having a maximum post-processing Signal to Interference plus Noise Ratio (SINR) after canceling influence of the estimated interference signal from the remaining precoding matrices.
