Provided is a base station device which communicates to/from a mobile station device supporting a MIMO scheme. A base station device (100) includes: a number-of-spatial-streams identification section (126) for identifying the number of spatial streams to be formed between the base station device and a mobile station device (200); a PRU-to-be-allocated identification section (128) for identifying at least part of a plurality of radio channels (PRUs), as a PRU to be allocated for forming the spatial streams whose number is identified by the number-of-spatial-streams identification section (126); and a message generating section (130) for transmitting, to the mobile station device (200), a single piece of control information which includes information indicating the number of the spatial streams, and information indicating the PRU to be allocated. |
