Patent ID: 8320356

Claim:
A wireless communication apparatus dividing a plurality of subcarriers forming a multicarrier signal into a plurality of subchannels and performing adaptive control per subchannel, the wireless communication apparatus comprising: a timing setter configured to set different transmission timings for the plurality of subchannels in accordance with a subchannel-specific timing offset which varies between cells; and a transmitter configured to transmit the multicarrier signal including the plurality of subchannels after the transmission timing setting, wherein the timing setter, in order to set the different transmission timings from transmission timings set by a wireless communication apparatus in a neighboring cell, sets a timing offset corresponding to at least a first subchannel of the plurality of subchannels to be longer than a timing offset of at least a first corresponding subchannel in the neighboring cell and sets a timing offset corresponding to a second subchannel of the plurality of subchannels which is different from the first subchannel to be shorter than a timing offset of a second corresponding subchannel in the neighboring cell.
