ABSTRACT:
Of any one of transmission method X of transmitting modulated signal A and modulated signal B including the same data from a plurality of antennas and transmission method Y of transmitting modulated signal A and modulated signal B having different data from the plurality of antennas, base station apparatus201does not change the transmission method during data transmission and changes only the modulation scheme. Base station apparatus201transmits modulated signal A and modulated signal B to communication terminal apparatus251using the determined transmission method and modulation scheme. In this way, it is possible to improve data transmission efficiency when transmitting data using the plurality of antennas.
