<p>A pilot signal transmitting method, which achieves an appropriate cell search without increasing in scale or complicating the mobile station structure, is provided along with a base station, a mobile station and a cellular system to which that method is applied. In a cell-specific pilot signal transmitting method for use in a mobile communication system that comprises a base station and a mobile station wireless communicating with the base station in the cell of a wireless communication area formed by the base station and that can mix and then transmit unicast data and broadcast/multicast data as downstream data from the base station to the mobile station, the difference between the start phase of a cell-specific pilot signal transmitted in a subframe in which the base station transmits the unicast data and the start phase of a cell-specific pilot signal transmitted in the next subframe is equal to the difference between the start phase of a cell-specific pilot signal transmitted in a subframe in which the base station transmits the broadcast/multicast data and the start phase of a cell-specific pilot signal transmitted in the next subframe.</p> |
