Patent ID: 8401100

Claim:
A transmission apparatus for transmitting a transmission signal to a reception apparatus using a plurality of subcarriers, the transmission apparatus comprising: a modulator that modulates a bit to generate a symbol; a repetition unit that duplicates the generated symbol to generate a plurality of same symbols; and a mapper that maps each of the plurality of same symbols onto the plurality of subcarriers in at least one of a frequency domain and a time domain, to generate the transmission signal, wherein: a position of each of the plurality of subcarriers onto which the plurality of same symbols are mapped is common between the transmission apparatus belonging to a first cell or a first sector and another transmission apparatus belonging to a second cell which is a neighbor cell of the first cell or a second sector which is a neighbor sector of the first sector, and wherein when a repetition factor in the transmission apparatus is different from a repetition factor in the other transmission apparatus, at least two symbols among the plurality of same symbols are mapped onto at least two subcarriers, positions of the at least two subcarriers being common between the transmission apparatus and the other transmission apparatus.
