PROBLEM TO BE SOLVED: To provide a technique for enhancing the throughput of a second system, by reducing interference between base stations of the second system.SOLUTION: A wireless communication system in which a plurality of base stations use the same frequency includes measurement means for measuring the channel estimate between a first base station on the interfered side and a second base station on the interfering side, in the first base station, multiplication means for multiplying a down-link transmission signal by a transmission weight depending on the channel estimate thus measured, and transmission means for transmitting the transmission signal thus multiplied from the second base station. |
