摘要： A terminal and a communication method thereof whereby, even in a case of employing the asymmetric carrier aggregation system and further employing the MIMO transmission method for upstream channels, the error characteristic of control information can be prevented from being degraded. In the terminal (200), a transport signal forming unit (212) forms transport signals by arranging, based on a arrangement rule, ACK/NACK and CQI in a plurality of layers. According to the arrangement rule, an error detection result is arranged, on a priority basis, in a layer that is different from a layer in which the channel quality information is arranged. In this way, the puncturing of CQI using ACK/NACK can be minimized, with the result that the error characteristic of control information can be prevented from being degraded.

摘要： Disclosed is a wireless communication apparatus and wireless communication method wherein flexible frequency scheduling is performed without increasing the scale of the DFT (Discrete Fourier Transform) circuitry. For example, when resource allocation information is reported indicating whether or not a resource has been allocated to each of a plurality of RBGs (RB groups) into which the system bandwidth is divided, as in Type 0 allocation, if the number of reported RBs reported by the resource allocation information cannot be expressed as “2^n×3^m×5^l”, an allocated RB number setting section (208) sets the number of allocated resource blocks used in the actual transmission band, corresponding to the reported RB number, to the number of resource blocks that can be represented by any of “2^n×3^m×5^l”, and an allocated RB selection section (209); selects the allocated RB employed in the actual transmission band from the resource allocation information and allocated RB number.

摘要： The present invention makes it possible to obtain the transmission diversity effect by applying a CDD while reducing the inter-code interference when performing a code multiplexing. When an Ack/Nack signal is transmitted from a user terminal to a base station in an upstream control channel by using an Ack/Nack resource, the signal is code-multiplexed by using a code sequence containing an orthogonal sequence and a cyclic-shifted sequence and transmitted from a plurality of user terminals to the base station. Upon using an aggregation size indicating the number of control signals of the downstream control channel, if the aggregation size is greater than one, it is determined that no resource located at the right of the axis of the cyclic-shifted amount of the cyclic-shifted sequence in the same orthogonal code of the orthogonal sequence is used, and the Ack/Nack signal to which CDD is applied from a plurality of antennas is transmitted by using a resource ACK #0 allocated to the own device and an unused resource ACK #1, which have the same orthogonal code, but have different cyclic-shifted amounts.

摘要： A radio transmission apparatus and a radio transmission method suppress lowering of the throughput caused by switching between the single carrier communication method and the multi-carrier communication method while suppressing increase in the signaling amount. A PHR threshold value setter sets a threshold value at a position greater by a predetermined value than the PHR at which the throughput performance of the SC-FDMA coincides with that of the OFDMA. A trigger signal transmission judger judges that a mobile station transmits a trigger signal for switching from the OFDMA to the SC-FDMA if the PHR in the OFDMA communication method is lower than the threshold value.

摘要： Provided are a wireless transmission device, a wireless reception device, and a bandwidth allocation method for, when non-contiguous bands allocation is performed, improving the frequency resource use efficiency of a system and thereby improving the system performance. RIV decoding unit (106) decodes start RBG# and end RBG# that are indicated by each RIV output from scheduling information decoding unit (104). Allocation boundary setting unit (107) previously adds a predetermined predetermined offset to the boundary of each RIV so that the boundaries of the allocations of respective RIVs are different from each other. Based on the start RBG# and end RBG# output from RIV decoding unit (106) and the boundaries of the allocations of respective RIVs output from allocation boundary setting unit (107), transmission bandwidth determination unit (108) determines, as allocated bandwidths, the bandwidths that are indicated by a plurality of RIVs and are not overlapped with each other.

摘要： Disclosed is a base station capable of minimizing in Type 0 assignment the number of resource block groups occupied by a terminal that performs frequency hopping, and thereby flexibly assigning resources in the Type 0 assignment. The base station (100) is used in a radio communication system in which a plurality of resource blocks constituting the system band thereof are grouped into resource block groups each consisting of P resource blocks, and the band that is not a PUCCH-assignable band to which PUCCHs assigned to both ends of the system band can be assigned is divided into a plurality of sub-bands. The base station (100) comprises an assignment unit (1102) and a demapping unit (112). The assignment unit (1102) assigns a plurality of resource blocks in units of resource block groups to terminal apparatuses to be subjected to noncontiguous-band assignment. The demapping unit (112) extracts, from a plurality of resource blocks in a second band, data signals for which frequencies are hopped by a frequency-hopping terminal apparatus from one to another of the plurality of sub-bands. Here, the bandwidth of each of the plurality of sub-bands is a natural-number multiple of P.
