<P>PROBLEM TO BE SOLVED: To suppress interference affecting a peripheral base station device while assuring a predetermined resource, and to prevent degradation in quality of control data of a control channel of the peripheral base station device. <P>SOLUTION: An IFFT part 105 generates an OFDM signal which contains control data assigned to an N (N is an arbitrary positive integer)OFDM symbol starting from a top of a subframe and PDSCH data assigned to an OFDM symbol behind the NOFDM symbol starting from the top, for each subframe, by subjecting the control data and the PDSCH data to an orthogonal frequency division multiplex processing. A transmission power control part 106, in the OFDM signal, controls to reduce transmission power of the PDSCH data whose transmission timing overlaps with a transmission timing of the control data of a peripheral base station device to be less than the transmission power of the PDSCH data whose transmission timing does not overlap with the transmission timing of the control data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
