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 wherein when both a first data and a second data, which has a greater importance than the first data, are placed in a single block, the BER characteristic of the second data can be well maintained. In this apparatus, a modulating part (101-1) modulates a first data sequence to generate a first data symbol, while a modulating part (101-2) modulates a second data sequence to generate a second data symbol. A placing part (102) places both the first data symbol and the second data sequence in each of blocks constituting a single carrier signal. At this moment, the placing part (102) places, in the single block, the first data at both ends of the block, while placing the second data, which has the greater importance than the first data, at the center of the block. A CP adding part (103) adds, to the head of the block in which the first and second data symbols are placed, a rear end portion of that block as CP.

摘要： Disclosed is a radio communication device that, even when a terminal erroneously receives a retransmission grant or a response signal from a base station, can reduce the number of other terminals in which the terminal interferes at a retransmission. In this device, a determination unit (205) determines a bandwidth between the two ends of a transmission band allocated to a transmitted signal at the retransmission of the transmitted signal. An allocation unit (209) allocates the transmitted signal to a frequency resource based on the bandwidth that is input from the determination unit (205). The determination unit (205) increases at the retransmission the amount of decrease in the bandwidth from the previous transmission, as the consecutiveness of the transmitted signal in the frequency region decreases.

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： A transmission/reception apparatus capable of preventing degradation in system capacity, improving system throughput, and minimizing power consumption of an apparatus is disclosed. In this apparatus, a propagation path determining section (131) determines a propagation path state in all the regions in the used frequency band of a received multicarrier signal based on propagation path estimation information such as a channel estimation value and the like calculated in a propagation path estimating section (126), and specifies a frequency region having a good propagation path state from the used frequency band of OFDM. More specifically, the used frequency band is divided into a plurality of frequency bands (subbands), each comprised of smaller predetermined bandwidth, and by selecting a subband having a good propagation path state in the propagation path determining section (131), a frequency region having the good propagation path state is specified. A transmitting section (110) reports the subband information to a base station.

摘要： Disclosed is an interleave pattern control device which can reduce a reception error percentage when an interleave pattern of a repetition symbol is controlled. In an interleave selecting unit (106) as the interleave pattern control device, calculation units (123-1 to 123-N) individually calculate the signal quality of the repetition synthesization result of pilot signals deinterleaved according to the candidates of interleave patterns. A pattern determining unit (124) determines the interleave pattern on the basis of the signal quality calculated.

摘要： A mobile station capable of reducing the probability of collision of RACH data in a random access. In this mobile station, a moving speed determining part (106) determines a moving speed of the mobile station (100). A frame selecting part (105) selects, based on both an arrangement pattern indicated by arrangement pattern information and the moving speed, one of frames to be used for transmission of RACH data. In accordance with a result of the selection, the frame selecting part (105) outputs the number of symbols per block to a block dividing part (113), and also outputs the number of duplications of each of blocks to a duplicating part (114). The block dividing part (113) divides the RACH data symbols, which are sequentially received from a modulating part (112), into blocks in accordance with the number of symbols per block received from the frame selecting part (105), thereby generating RACH data blocks. The duplicating part (114) duplicates the RACH data blocks in accordance with the number of duplications received from the frame selecting part (105).

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.
