<p>The objective of the present invention is for a base station device to efficiently control transmission of an uplink signal with respect to a mobile station device. The invention has: a transmit power setting unit for setting a transmit power for a physical uplink shared channel using any one of path losses among a plurality of calculated path losses; and a power headroom generation unit which generates a first power headroom, which is information related to allowance of the transmit power, using a bandwidth of resources that have been assigned for the physical uplink shared channel, and the path loss used for setting the transmit power of the physical uplink shared channel, and which generates a second power headroom, which is information related to the allowance of the transmit power, without depending on the bandwidth of the resources that have been assigned for the physical uplink shared channel, using, among the calculated plurality of the path losses, the path loss that has not been used for setting the transmit power of the physical uplink shared channel.</p> |
