    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.

    摘要： In DFT-s-OFDM, disclosed are a wireless transmission apparatus and wireless transmission method whereby freedom of allocation of frequencies is secured, while increases of CM are avoided. An SD number determination unit (152) determines an SD number based on the channel quality information of a mobile station and a threshold value that is set by a threshold value setting unit (151). A transmission bandwidth determination unit (153) determines the transmission bandwidth necessary for transmission of the transmission data. An allocation commencement position determination unit (154) determines the position for commencement of allocation of transmission data. If the SD number is equal to or more than the threshold value, a divided bandwidth determination unit (155) sets all the divided bandwidths to equal values and a frequency interval determination unit (156) sets all the frequency intervals to equal values.

    摘要： A radio transmitting apparatus and a radio transmitting method wherein the increase of the guard time in a random access region is reduced to secure the data transmitting region of an upstream line. In this apparatus, when a received signal power estimated by a received signal power estimating part (205) is the higher, a RACH format selecting part (206) selects a RACH format having the longer frame length. Contrarily, when a received signal power estimated by the received signal power estimating part (205) is the lower, the RACH format selecting part (206) selects a RACH format having the shorter frame length. A RACH data part arranging part (207) appropriately selects, in accordance with the selected RACH format, top-priority information, such as terminal identifiers, priority information, such as connection request information or band assignment request information, and non-priority information and arranges RACH data parts.

    摘要： A radio transmission device and a radio communication method employ sequence length decision units which hold a correspondence in which one basic sequence length is set for a plurality of transmission bandwidths. The sequence length decision units acquire transmission bandwidth information and decide a sequence length corresponding to the acquired transmission bandwidth information. A decision is made as to which of the cyclic extension process or the truncation process is to be executed on a Zadoff-Chu sequence according to the sizes of the acquired transmission bandwidth information and the basic sequence length. Then, a difference between the transmission bandwidth and the basic sequence length, i.e., the number of possible cyclic extension/truncation symbols, is obtained.

    摘要： Provided is a sequence allocation method capable of reducing inter-cell interference of a reference signal when a ZC sequence is used as the reference signal in a mobile communication system. In the sequence allocation method divides R×M sequences specified by a ZC sequence number r (r=1 to R) and a cyclic shift sequence number m (m=1 to M) into a plurality of sequence groups X (X=1 to R) in accordance with the transmission band width of the reference signal, so that the ZC sequence is allocated to each cell in each sequence group unit. When it is assumed that R=9 and M=6, the number of sequence is 54. Each of the sequence groups is formed by two sequences. Accordingly, the number of sequence groups is 27. The 27 types of sequence groups are allocated to each cell.
