Abstract: PURPOSE: An apparatus and a method for eliminating inter-cell interference in a multiple input multiple output wireless communication system are provided to select a PMI(Precoding Matrix Index) according to a priority set by a priority index, thereby efficiently eliminating inter-cell interference. CONSTITUTION: The channel quality about a serving base station is measured(201). If the channel quality is lower than a threshold value, interference power received from neighboring base stations is measured(203). PMIs and priority indexes about each neighboring base station are calculated(205). At least one of the PMI, PMI type indicator, the priority indexes and the channel quality is fed back to the serving base station(207).

Abstract: A codebook generation method for a multi-polarized MIMO(Multi Input Multi Output) system and a device therefore are provided to reconfigure a precoding matrix according to transmission ranks, thereby more efficiently offering a codebook. A single-polarized precoding matrix is allocated to diagonal blocks(S210). A zero matrix is allocated to the rest of blocks except the diagonal blocks(S220). A precoding matrix is generated by combining the single-polarized precoding matrix with the zero matrix(S230). The precoding matrix is reconfigured by selecting at least one column vector(S240). A rotation precoding matrix is generated(S250). Phases of each element included in the realigned matrix are controlled by using a diagonal matrix(S260).

Abstract: A codebook generation method for a multi-polarized MIMO(Multi Input Multi Output) system and a device therefore are provided to generate a rotation matrix if polarized directions of transmission antennas are rotated, thereby more flexibly coping with changes of the polarized directions of the transmission antennas. A single-polarized precoding matrix allocator(510) allocates a single-polarized precoding matrix to diagonal blocks of plural blocks divided according to the number of polarized directions of transmission antennas. A zero matrix allocator(520) allocates a zero matrix to the rest of the blocks except the diagonal blocks. A precoding matrix generator(530) generates a precoding matrix by combining the zero matrix with the single-polarized precoding matrix.
