Abstract
A wireless communication method of a base station that transmits a modulation signal based on an orthogonal frequency division multiplexing scheme to a plurality of terminals. The method includes determining, for each terminal of the plurality of terminals, which subcarrier group or how many symbols along a time axis are to be allocated in a transmission frame, the transmission frame including a first period in which first transmission symbols are arranged and a second period in which second transmission symbols which are different from the first transmission symbols are arranged. The method also includes forming the transmission frame according to a determined allocation, wherein a plurality of symbols on a frequency axis for transmitting N bits (N is a natural number) are arranged within a part of the first period, by using a modulation scheme whereby N bits can be transmitted using one symbol. The method further includes transmitting the modulation signal using the transmission frame.
