Abstract
Provided is a base station device capable of suppressing power consumption of a radio communication device and transmitting a pilot signal for measuring an uplink channel quality in a high frequency use efficiency. The base station device (2) includes: a resource block size decision unit (54) which decides the number of subcarriers to be allocated for the radio communication device (1); and a cyclic shift delay amount decision unit (55) which sets a cyclic shift delay amount used when performing cyclic shift delay diversity transmission according to the number of subcarriers decided by the resource block size decision unit (54). By using the cyclic shift delay amount set by the cyclic shift delay amount decision unit (55), the radio communication device (1) cyclic shift delay diversity transmission of the channel quality measuring signal.
