摘要： There are disclosed a wireless communication apparatus and a wireless communication method whereby a flexible frequency scheduling can be performed without increasing the circuit scale of DFT (Discrete Fourier Transform). In a terminal (200), a number-of-allocated-RBs setting unit (209) sets a number of allocated RBs, which is to be used for an actual transmission band corresponding to the number of notified RBs, to a number of resource blocks that can be expressed by one of “2n×3m×5l”. The allocated RB selecting unit (210) selects, based on the resource allocation information and the number of allocated RBs, either an unused one of the notified RBs that is not used as the transmission band or an additional RB that is added to the notified RBs and used as the transmission band.

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： Disclosed are a wireless communication method, a wireless communication base station device, and a wireless communication terminal device that dynamically switch the transmission slot of an SRS of each terminal within a cell while suppressing an increase in the number of signaling bits. A terminal (100) and a base station (200) are each provided with a table wherein FH flags for SRS and transmission power data of each slot are mapped to two-bit notification bits. In this table, transmission power data indicating SRS transmission by slot 1 and slot 2 and FH flags are mapped, and an FH flag is not mapped to transmission power data indicating SRS transmission by slot 1 or slot 2. The base station (200) notifies the terminal (100) of the FH flag data and the SRS transmission power data by means of transmitting scheduling data containing the notification bits to the terminal (100).

A bundling determination unit (132) of a terminal (100) determines parameters that denote the allocated resource quantities that are allocated thereto from a base station (200), or in other words, a downstream band that is included in a bundling group and a downstream band that is not included in the bundling group, from among a plurality of downstream bands on the basis of base station transmission parameters. Specifically, a degree of resource share (Xn) that is allocated from each respective downstream band to the terminal (100) is employed in the base station transmission parameters.
