Abstract
A transmission method simultaneously transmitting a first modulated signal and a second modulated signal at a common frequency performs precoding on both signals using a fixed precoding matrix and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.
Claims2
A communication method performed by a mobile terminal configured to switch between a first communication mode and a second communication mode, the communication method comprising:
- in the first communication mode, receiving first data and second data from a first transceiver and a second transceiver in a first frequency band and a second frequency band, respectively, at an identical time, the first data being identical to the second data, and the first frequency band being identical to the second frequency band, and
- in the second communication mode, receiving third data from the first transceiver in a third frequency band or fourth data from the second transceiver in a fourth frequency band, the third data being different from the fourth data, and the third frequency band being different from the fourth frequency band.
