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 sequence allocating method and a sequence allocating 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. According to these method and apparatus, 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： Disclosed is a radio transmission device for lightening the waveform distortion of a received signal in a single-carrier transmission irrespective of a fading state. In this device, an FFT unit (103) converts a modulation signal outputted from a modulation unit (102), into a signal of a frequency range, and a repetition unit (104) repeats the frequency range signal outputted from the FFT unit (103), and arranges a plurality of frequency range signals adjacent to each other on a frequency axis. A tooth-shaped waveform forming unit (105) shapes the waveform of the frequency range signals outputted from the repetition unit (104), into a tooth-shaped waveform, and an IFFT unit (106) converts the frequency range signal outputted from the tooth-shaped waveform forming unit (105), into a signal of a time range.

摘要： Disclosed are a radio communication system, a radio transmission device, a RACH transmission method capable of reducing the important information conflict probability and improve the communication system throughput in a channel transmitted at a random timing such as RACH. In a frame configuration used by the communication system, the number of slots of RACH is reduced by one and the resource for the slot is equally allocated as a resource for a pilot/UE-ID of other slot. This increases the resource amount of the pilot/UE-ID. Furthermore, the resource of the pilot/UE-ID is divided into a plurality of sub slots, which are allocated as resource blocks for respective mobile stations.
