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： 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.

摘要： A mobile station apparatus includes a receiving unit configured to receive control information; a selecting unit configured to randomly select a sequence from a plurality of sequences contained in one group of a plurality of groups, into which a predetermined number of sequences generated from a plurality of base sequences are grouped and which are respectively associated with different amounts of data or reception qualities; and a transmitting unit for transmitting the selected sequence. The predetermined number of sequences are grouped by partitioning the predetermined number of sequences, in which sequences generated from the same base sequence and having different cyclic shifts are arranged in an increasing order of the cyclic shifts. A position at which the predetermined number of sequences are partitioned is determined based on the control information, and a number of sequences contained in each of the plurality of groups varies in accordance with the control information.

摘要： Provided is a radio communication base station device capable of obtaining a large multi-user diversity effect while suppressing increase of overhead of a communication signal. The radio communication base station device includes a scheduler (101) which performs scheduling for allocating RB (Resource Block) to terminals belonging to a first group by FSA (Frequency Scheduled Allocation) in accordance with line quality of each terminal and each RB and allocating remaining RB other than the RB allocated to the terminals belonging to the first group, to terminals belonging to a second group according to a predetermined allocation rule. That is, the scheduler (101) performs RB allocation to the terminals belonging to the first group with a higher priority than RB allocation to the terminals belonging to the second group. Each time the scheduler (101) performs FSA, it outputs the result of the FSA to the terminals belonging to the first group to an encoding unit (102) and an extraction unit (111) and does not output any scheduling result to the terminals belonging to the second group.

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.
