Abstract

In a communication system provided with a plurality of base stations, first and second known signals are defined as known signals to be transmitted by the communication terminal. A plurality of carriers for use in transmission of the first known signal and a plurality of carriers for use in transmission of the second known signal are alternately arranged in a frequency direction in the first and second known signals in the same transmission frequency band. In each base station, at the time of transmitting a signal to a communication terminal that transmits the first known signal, the communication unit which transmits the communication terminal by use of a plurality of antennas performs null-steering in relation to transmission directivity at the plurality of antennas based on the first known signal from the communication terminal.
