Abstract:
1. A radio communication base station apparatus that transmits a multicarrier signal comprised of a plurality of subcarriers and that communicates with a plurality of radio communication mobile station apparatuses, which have respectively different capabilities for performing communication in different bandwidths, the radio communication base station apparatus comprising: a setting section that sets a transmission band for a broadcast channel signal, which is addressed to all of the plurality of radio communication mobile station apparatuses, to one of a plurality of first frequency bands in a second frequency band, the second frequency band being divided into the plurality of first frequency bands, each of the first frequency bands having a minimum bandwidth of the different bandwidths; a generating section that generates the multicarrier signal by mapping the broadcast channel signal on a subcarrier in the transmission band set by the setting section out of the plurality of subcarriers; and a transmitting section that transmits the multicarrier signal to the radio communication mobile station apparatuses, wherein the setting section changes over time the first frequency band which is set as the transmission band in the second frequency band.
