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 radio communication system, a radio transmission device, and a Random Access Channel (RACH) transmission method capable of reducing the important information conflict probability and improving 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/User Equipment-Identification (UE-ID) of other slots. 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.

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 are a radio sending device and a radio sending method for improving a throughput while keeping a receiving quality. In this radio sending device, an MCS switching control unit (102) applies an MCS parameter having a lower quality required than that of the MCS parameter to be applied to send data arranged at other than the two end portions of a block, to send data arranged at the two end portions of the block, and a CP adding unit (105) adds such a CP to the leading end of the block as is created by copying the trailing end portion of the block composed of the send data, to which the MCS parameter is applied by the MCS switching control unit (102), with a length less than the delay time of the maximum delay wave. A send RF unit (106) sends the send data, in which the CP is added to the leading end of the block, from an antenna (107).

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 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.
