ABSTRACT:
A transmission method includes transmitting a signal using an orthogonal frequency division multiplexing, receiving the transmitted signal at a plurality of reception devices, and controlling a transmission power for first signals transmitted to the plurality of reception devices in an area formed by the transmitter to be greater than a transmission power for second signals transmitted to a specific device in the area, wherein said first signals and said second signals are time division multiplexed.
