Abstract:
1. A base station for transmitting common information which is used in common by plural mobile stations operating at different frequencies, comprising: a common information generating unit configured to generate the common information including common control information and information indicating that the common control information is changed; a lower-layer control information generating unit configured to generate lower-layer control information indicating a radio resource where the common information is to be placed; a multiplexing unit configured to multiplex the lower-layer control information into each of a plurality of frequency blocks included within a system bandwidth and multiplex the common information into one or more frequency blocks, the system bandwidth being divided into the plurality of frequency blocks each corresponding to a minimum value of maximum transmission and reception bandwidths used by the plural mobile stations, and the number of the one or more frequency blocks being smaller than the number of frequency blocks including the lower-layer control information; and a transmitting unit configured to transmit the multiplexed lower-layer control information and common information at said different frequencies.
