Abstract:
A base station apparatus in a radio communications system is disclosed. The base station apparatus communicates with a mobile station using an OFDM scheme in downlink. The base station apparatus includes a sync signal generating unit which generates a secondary sync channel; a multiplying unit which multiplies a scramble code with the secondary sync channel; and a transmitting unit which transmits the secondary sync channel with which the scramble code is multiplied. Cell-specific information is detected by the secondary sync channel.
