    摘要： Provided is a mobile station capable of effectively reporting control information in RACH. In the mobile station, a signature selection unit (111) selects one of different code sequences as a signature according to inputted control information and a modulation unit (112) modulates a signature (code sequence). In a table provided in the signature selection unit (111), for control information ‘000’, CAZAC sequence #1 as a basic code sequence and a derived code sequence of shifts 0 to 7 derived from the CAZAC sequence #1 are set while being correlated to each other. The derived code sequence of shifts 0 to 7 of the CAZAC sequence #1 respectively correspond to signatures #1 to #8. Moreover, for control information ‘001’, CAZAC sequence #2 as a basic code sequence and a derived code sequence of shifts 0 to 7 derived from CAZAC sequence #2 are set while being correlated to each other. The derived code sequence of shifts 0 to 7 of the CAZAC sequence #2 respectively correspond to the signatures #9 to #16.

    摘要： A wireless communication terminal apparatus wherein the occurrences of inter-sequence interferences between cells can be reduced. In this apparatus, a sequence number deciding part (105) has a table in which the sequence numbers of a plurality of Zadoff-Chu sequences having different sequence lengths are associated with the sequence group numbers of a plurality of sequence groups into which the Zadoff-Chu sequences are grouped and with the transmission bandwidths of reference signals. In accordance with a sequence group number and a transmission bandwidth both received from a decoding part (104), the sequence number deciding part (105) refers to the table to decide the sequence number of a Zadoff-Chu sequence. In the table of the sequence number deciding part (105), different sequence-number start-positions are established for the Zadoff-Chu sequences having the different sequence lengths.

    摘要： Provided are a radio transmission device and a radio transmission method, which prevent the deterioration of a preamble detecting performance while reducing the collision probability of a RACH. In this radio transmission device, a Signature table storage unit (103) divides the magnitudes of transmission loss levels into individual levels corresponding to the distances from a base station, to cause CAZAC series and circulation shift quantities to correspond to each other at the individual levels, and is provided with a table containing a plurality of Signatures created from the CAZAC series and the circulation shift quantities caused to correspond to each other. A Signature selecting unit (104) selects one of the corresponding Signatures at random from the Signature table storage unit (103), on the basis of the magnitude of the transmission loss level outputted from a transmission loss level deciding unit (102). A RACH signal generating unit (105) generates the RACH signal with the Signature selected.

    摘要： It is possible to provide a radio transmission device and a radio transmission method capable of improving resource use efficiency without increasing or decreasing the number of Signatures. The device and the method use a Signature table having Access types, DL CQI, and Signatures uniquely correlated to one another. In this Signature table, the DL CQI level is set for each Access type in accordance with the data amount transmitted/received before a data communication start after a transmission of RACH. When the Access type is IDLE, the data amount is greater as compared to other Access types and the DL CQI is set to level 1 to 6. When the Access type is ACTIVE, the data amount is smaller as compared to other Access types and the DL CQI is set to smaller than level 3 and greater than level 4. Furthermore, when the Access type is Handover, the data amount is middling as compared to other Access types and the DL CQI is set to level 1 to 3 or above.
