<p>There are provided a base station device transmitting a frame capable of performing cell search without being affected by arrangement of a pilot channel and a mobile station device performing cell search by using the frame. In the base station device (100), a frame formation unit (120) forms a frame by arranging a P-SCH sequence used for synchronization of a frame timing on some symbols of multi-carrier symbols at a predetermined position from the frame head in the frequency direction and arranging an S-SCH sequence corresponding to a base station scrambling code so that it is not overlapped on some of the multi-carrier symbols at a predetermined position from the frame head with the same symbol as the frame synchronization sequence. The frame is received by the mobile station device (200) and the S-SCH is demodulated. Thus, it is possible to directly identify the base station scrambling code without using a pilot channel.</p>
