1. mobile station apparatus, comprising:

  • Receiving element, receives the OFDM symbol sent from base station;

    Cyclic Prefix removing unit, removes the Cyclic Prefix be attached in the described OFDM symbol received;

    Fast Fourier transform unit, carry out fast Fourier transform for the described OFDM symbol being removed described Cyclic Prefix, output packet is containing the signal distributing to the assignment information of or the multiple control channel unit of sequence number continuous print, search volume information and downlink data;

    Separative element, comprises the broadcast message of search volume information from exported described Signal separator;

    Broadcast message decoding unit, decodes to isolated described broadcast message, to obtain described search volume information;

    Extraction unit, according to control channel unit polymerization size and described search volume information, extracts described assignment information, and this control channel unit polymerization size is the quantity of described or the multiple control channel unit of sequence number continuous print being assigned with described assignment information;

    Demodulating unit, carries out demodulation to the described assignment information extracted;

    Decoding unit, according to described control channel unit polymerization size, search volume is used to decode to the described assignment information after demodulation, the search volume of described search volume for being defined by control channel unit number and control channel unit number, this control channel unit number is corresponding by described control channel unit polymerization size, the starting position of search volume, and this control channel unit number is search volume length;

    AndIdentifying unit, judges decoded described assignment information whether as the assignment information mailing to this device.
