    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 terminal apparatus is disclosed wherein even in a case of applying SU-MIMO and MU-MIMO at the same time, the inter-sequence interference in a plurality of pilot signals used by the same terminal can be suppressed to a low value, while the inter-sequence interference in pilot signal between terminals can be reduced. In this terminal apparatus (200): a pilot information deciding unit (204) decides, based on allocation control information, Walsh sequences of the respective ones of first and second stream groups at least one of which includes a plurality of streams; and a pilot signal generating unit (205) forms a transport signal by using the decided Walsh sequences to spread the streams included in the first and second stream groups. During this, Walsh sequences orthogonal to each other are established in the first and second stream groups, and users are allocated on a stream group-by-stream group basis.

In a terminal (200), a PDSCH receiving unit (208) receives first and second code words, which comprise code word block (CWB) groups to be mapped to the respective ones of a plurality of downstream unit bands, and detects errors of the CWBs; and an A/N bundling unit (216) transmits, based on a bundling rule in which each CWB is associated with any one of first and second bundling groups, a single bundle of response signals into which the error detection results are bundled for each bundling group. According to the bundling rule, at least one of the first and second bundling groups includes both the CWB belonging to the first code words and the CWB belonging to the second code words.

    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： Provided are a wireless communication terminal apparatus, a radio communication base station apparatus and a wireless communication method whereby the increase in the number of signaling bits can be suppressed, while the SRS capacity can be improved. RS type determining unit (105) determines, based on scheduling information, that the signal is an SRS signal accompanied by no data or a DMRS signal accompanied by data. CS amount deciding unit (106) holds a CS amount for DMRS and a CS amount for SRS that are defined such that the CS amount for SRS includes a CS amount not included in the CS amount for DMRS. The CS amount deciding unit (106) uses CS amount notification information, which is included in the scheduling information, and the CS amount definition to derive a CS amount in accordance with the RS type outputted from the RS type determining unit (105).

    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.
