摘要： A base station device is provided with features in which multicast data can be prevented from deterioration in the accuracy of channel estimation due to interference of a unicast data pilot signal when multicast data and unicast data are multiplexed for transmission. In this device, a unicast pilot signal generating unit (105-1) generates a unicast data pilot signal, a multicast pilot signal generating unit (105-2) generates a multicast data pilot signal, a disposing unit (106) disposes a unicast data symbol, a multicast data symbol, the unicast data pilot signal, and the multicast pilot signal at either position on a two-dimensional plane comprised of a frequency axis and a time axis to output them to an IFFT unit (107). In this case, the disposing unit (106) disposes the multicast data pilot signal at a position on the two-dimensional plane comprised of the frequency axis and the time axis where the unicast data pilot signal does not interfere with it.
