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： 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.

摘要： A radio transmitting apparatus and a radio transmitting method wherein the increase of the guard time in a random access region is reduced to secure the data transmitting region of an upstream line. In this apparatus, when a received signal power estimated by a received signal power estimating part (205) is the higher, a RACH format selecting part (206) selects a RACH format having the longer frame length. Contrarily, when a received signal power estimated by the received signal power estimating part (205) is the lower, the RACH format selecting part (206) selects a RACH format having the shorter frame length. A RACH data part arranging part (207) appropriately selects, in accordance with the selected RACH format, top-priority information, such as terminal identifiers, priority information, such as connection request information or band assignment request information, and non-priority information and arranges RACH data parts.

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： 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： 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.
