摘要： Disclosed are a radio transmission device and a radio transmission method which reduce the RACH conflict ratio and improve the RACH detection characteristic. When the device and the method are used: as the number of signature numbers allocated for UE by the network side increases, the condition for allocating a signature by UE itself is mitigated and an expectation value which is a statistic average value of the RA quantity using the signature allocated by UE for itself is decreased; and as the number of signature numbers allocated for UE by the network side decreases, the condition for allocating a signature by UE itself is limited and an expectation value of the RA quantity using the signature allocated by UE for itself is increased.

摘要： Provided is a communication device, which is enabled to improve the throughput of a communication system by reducing the difference of a transmission power between an SCCH and an SDCH thereby to satisfy the required quality of a PAPR. In this device, an MCS selection unit (111) of a transmission unit (110) decides, with reference to a CQI lookup table, an MCS pattern (MCS1) of the SDCH, an MCS pattern (MCS2) of the SCCH and information (multiplex information) on multiplex positions on the time axes of those two channels, on the basis of the CQI information. On the basis of the MCS2 and the MCS1, encoding modulation units (112 and 113) perform encoding and modulating operations. According to the multiplex information, a channel multiplexing unit (114) time-division multiplexes the SCCH and the SDCH thereby to generate a transmission signal.

摘要： Disclosed are a sequence report method and a sequence report device for reducing a signaling amount for reporting a Zadoff-Chu sequence or a GCL sequence allocated for a cell. Indexes starting at 1 are correlated to different ZC sequences and are allocated for cells so that the indexes are continuous. When such ZC sequences are reported from BS to UE, a start index indicating the start of the continuous indexes is combined with the number of allocated sequences and they are reported as allocation sequence information by a report channel. The UE and the BS share the correlation between the ZC sequences and the indexes and the UE identifies a usable sequence number according to the correlation and the allocation sequence information reported from the BS.

摘要： It is possible to provide a radio transmission device and a radio transmission method which can avoid degradation of a channel estimation accuracy using a reference signal formed by a ZC sequence even when the RS transmission band of a local cell is different from that of an adjacent cell. A mobile station decides a cyclic shift sequence corresponding to RB allocation information from an RS table which correlates different frequency bandwidths from a reference point of respective transmission bands to a spectrum start number of the cyclic shift sequence so as to satisfy a particular relationship based on the sequence length and transmits the decided cyclic shift sequence as RS to a base station. The base station uses the same RS table as the RS table of the mobile station and performs correlation calculation of the RS transmitted from the mobile station, thereby performing channel estimation.

摘要： Provided is a radio transmission device, which is enabled to improve a reception quality by improving the channel estimation precision of specific data such as control data. In this device, a mapping control unit (109) acquires pilot position information (at ST1010), and determines a resource block or a candidate for the mapping position of control channel data (at ST1020). The mapping control unit (109) also determines a resource block other than that candidate as the mapping position of other data (at ST1030). Moreover, the mapping control unit (109) generates a mapping control signal for instructing a mapping unit (104) the candidate of the mapping position of the control data and the mapping position of other data, that is, a mapping method, and outputs the generated mapping control signal to the mapping unit (104).

摘要： A sequence allocating method and apparatus wherein in a system where a plurality of different Zadoff-Chu sequences or GCL sequences are allocated to a single cell, the arithmetic amount and circuit scale of a correlating circuit at a receiving end can be reduced. In ST201, a counter (a) and a number (p) of current sequence allocations are initialized, and in ST202, it is determined whether the number (p) of current sequence allocations is coincident with a number (K) of allocations to one cell. In ST203, it is determined whether the number (K) of allocations to the one cell is odd or even. If K is even, in ST204-ST206, sequence numbers (r=a and r=N−a), which are not currently allocated, are combined and then allocated. If K is odd, in ST207-ST212, for sequences that cannot be paired, one of sequence numbers (r=a and r=N−a), which are not currently allocated, is allocated.

摘要： A radio transmitting apparatus and a radio transmitting method wherein the throughput is improved and a fast initial access processing including an RA burst is accomplished. According to these apparatus and method, a signature table storing part (101) has a plurality of signature groups generated from a plurality of different Zadoff-Chu sequences with a set of signatures generated from one Zadoff-Chu sequence being one signature group. A signature sequence assignment control part (102) switches signature groups to be assigned to a UE for each of paging transmissions, thereby assigning a signature sequence, which is to be used for an initial RA, from the same signature group. A paging information generating part (104) causes the ID of the assigned signature sequence to be included into paging information, which is then transmitted to the UE.
