A transmitting method, comprising: configuring a frame using a plurality of orthogonal frequency-division multiplexing, OFDM, symbols, by allocating time resources and frequency resources to a plurality of transmission data; and transmitting the frame, characterized in that the frame includes a first period in which a preamble (201, 202) which includes information on a frame configuration of the frame is transmitted, and a second period in which the plurality of transmission data are transmitted by using respective one of a plurality of time-frequency regions, the time-frequency region is identified by at least one time resource and at least one frequency resource, for each of the plurality of time-frequency regions, a number, V, of data symbols generated from the transmission data are mapped onto a part of the time-frequency region ($10001-$13995), and U-V dummy symbols are mapped onto the time frequency region ($13995-$14000), wherein U is a number of symbols included in the time-frequency region, the V data symbols are mapped onto time resources identifying the time-frequency region that have a time index smaller than or equal to a first certain value, that data symbols of the V data symbols that are mapped onto time resources identifying the time-frequency region that have a time index equal to the first certain value are mapped onto frequency resources identifying the time-frequency region that have a frequency index smaller than or equal to a second certain value, the U-V dummy symbols are mapped onto time resources identifying the time-frequency region that have a time index greater than or equal to the first certain value, and that dummy symbols of the U-V dummy symbols that are mapped onto time resources identifying the time-frequency region that have a time index equal to the first certain value are mapped onto frequency resources identifying the time-frequency region that have a frequency index greater than the second certain value, quadrature components of the dummy symbols have zero amplitudes, in-phase components of the dummy symbols are set to +1 or -1 according to a pseudo-random sequence, and among the plurality of OFDM symbols, OFDM symbols included in the second period include pilot symbols arranged along a time axis with a predetermined spacing therebetween, the data symbols, and the dummy symbols. configuring a frame using a plurality of orthogonal frequency-division multiplexing, OFDM, symbols, by allocating time resources and frequency resources to a plurality of transmission data;
