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： 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.

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.
